2023 Hyundai Santa FE Hybrid

Defect. Hyundai Motor America (Hyundai) is recalling certain 2019-2023 Santa Fe, 2021-2023 Santa Fe HEV, 2022-2023 Santa Fe Plug-in HEV and Santa Cruz vehicles potentially equipped with a tow hitch harness installed as original equipment, or purchased as an accessory through a Hyundai dealership. Water accumulation on the tow hitch harness module printed circuit board (PCB) may cause an electrical short, which can result in a fire.

Risk. A fire while parked or driving can increase the risk of injury.

Remedy. Owners are advised to park their vehicles outside and away from structures until the remedy is completed. Dealers will install a new fuse and wire extension kit as necessary, free of charge. Owner notification letters were mailed starting May 16, 2023. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 244. This recall is an expansion of previous recall number 22V-633.

The vehicle came to a complete stop filling cabin with smoke and wouldnt start in a bend on road blocking entrance ramp. Its available for inspection but at dealership. My safety was put at risk for collision as well as health with cabin filling with smoke. The dealer still has vehicle going on 3rd day without answers. The vehicle had warning come on for hybrid system failure appearing shortly before dying completely with smoke filling cabin.

I am submitting this formal safety complaint regarding a structural defect in my 2023 Hyundai Santa Fe Hybrid that I believe poses a safety concern and warrants federal investigation under the National Traffic and Motor Vehicle Safety Act (49 U.S.C. § 30101 et seq.). The vehicle exhibits a persistent and recurring structural creak originating from the pinch weld area adjacent to the hybrid battery storage compartment — specifically at a metal-on-metal contact point above the rear driver-side wheel well. The noise presents most prominently at low speeds over uneven surfaces, driveway transitions, and speed bumps. The root cause, as identified by service documentation and owner community reports, is a manufacturing defect in the pinch weld construction where two metal body components make contact due to insufficient clearance tolerances. This affects the structural integrity of the body-in-white in proximity to the hybrid high-voltage battery system. III. SAFETY SIGNIFICANCE I am reporting this as a safety concern for the following reasons: •The defect involves structural body components adjacent to the high-voltage hybrid battery storage compartment. Any degradation of body structure in this area presents a potential risk of battery exposure, puncture, or damage in collision scenarios; •The metal-on-metal contact at the pinch weld constitutes an ongoing structural stress point that may accelerate fatigue and cracking of load-bearing body components over time; •The defect is pr

Own a 2023 Hyundai Santa Fe Hybrid and have experienced the following issues over the past year and a half. Beginning after maybe 40,000 miles we pulled out onto a roadway and the engine immediately lost power and started flashing a glaring red warning that the hybrid system was failing and to pull over. We luckily were able to and turned the car off and waited. I tried to turn it on and it came back to life as if there was never an issue? We drove off. it left no warning code or did not update my Bluelink App. I took it to the dealership and they could not find any issues. Fast forward another 5 or 6 months and it happens again. Take it to the dealer and they keep it a week to go over it but still nothing. Within a week of getting it back it happens again and this time I am videoing it happening to me. Back to the dealer and provide the video because again the car did not log the event nor did it update my app. They hold it again for a week and try different things. They still cannot figure it out and I get it back.... it happens again.... This time the dealership was able to come up with an answer and that the oil level was too high. I got the car back and it seemed to work. Probably now 6 months go by and then this week I drive over to Jacksonville (5 hr drive) and visit. Again the car scares us on the highway and I have to pull over. Havea friend meet us with tools and we jack up the car and let out enough engine oil to insure we can read between the two marks on the dips

One two separate occasions while driving the car has lost the ability to accelerate. There is no acceleration power even when completely flooring the gas pedal. The dash displays a red circle warming that states "Check Hybrid system. Stop Safely". I have had to coast to the side of the road and then the car shuts off. It has taken several minutes before it can start again, and then displays a warning "Park with engine On to charge battery" before being able to shift the car into drive. I immediately took the vehicle to the dealership at which I had purchased the car. They have run a diagnostic on it and did not find any error codes stored in the computer. I picked up the vehicle from them and immediately upon pulling out of their lot it happened again. After losing power, coasting to the side of the road, and waiting for the engine to be able to restart I took it immediately back to the dealership. They have had my car for 5 weeks and cannot diagnose the problem or offer any recommendations for repairs.

The vehicle will not accelerate and comes to a complete stop while driving. Within days, it displayed ‘Check Hybrid System. Stop safely’ and lost propulsion while driving.

On September 4, 2025 as I pulled on to Interstate I-70 my car suddenly lost power. Gas engine died. Loud attention sound started. Instrument cluster started flashing red with message "EV system failure, stop immediately" EV battery showed full depletion although a moment before it showed about 75% power. There was only enough propulsion to keep moving slowly. Since this was a construction zone the shoulder was blocked off and roadway was reduced to only one lane. I had no where to go. A large truck narrowly avoided rear ending me. I was scared and felt helpless. Eventually I was able to pull off and shut off the car. It was able to be re-started immediately with no warning indicators and EV battery power restored. This loss of power has happened 6 times before during the time I have owned the car. Last time was in March 2025. Each previous time it happened I was traveling at about 35 miles per hour and while annoying I did not fear for my life. On March 6, 2025 I had the dealer, McCarthy Hyundai, check out this problem. There were no detectable problems or problem codes. I was told that it might have been caused by the oil dip stick not being fully seated. It was obvious they had no clue what caused this but that I should come back if it happened again. I have reported this to Hyundai customer service who would not confirm that this was a problem encountered by many others. From looking at reports on the internet, my problem is not unique except for being life thretening. Cus

I am reporting a serious and recurring safety defect with my 2023 Hyundai Santa Fe Hybrid, purchased new in January 2024. The vehicle has suffered from over 30–40 sudden hybrid system failures, including loss of acceleration, “Stop Vehicle” warnings, and check engine lights. These incidents happen without warning, including while driving at legal speeds (40–70 mph), on residential streets and highways. Most recently, the car failed twice in two days, while my teenage son was driving within all road laws, including once with a friend in the car. The vehicle simply stopped accelerating in the middle of traffic, endangering them and everyone around them. These failures have happened at legal speeds ranging from 40–70 mph, on both residential roads and highways. There is no advance warning, just abrupt loss of power and sudden warning messages. We’ve taken the vehicle to the South Charlotte Hyundai dealership multiple times. Each time, they either reset the check engine light or replaced indicators: but never addressed the root hybrid system failure. We filed a lemon law case, and Hyundai responded with only a $2,000 offer including legal fees, requiring us to keep the dangerous vehicle. We rejected the offer. These failures have occurred with children and passengers in the car. We have documented as many incidents as we could, including photos, service records, and communication with Hyundai. The vehicle is available for inspection upon request. I no longer feel safe driving or

We were driving in Montana down [XXX] and heard a very large “pop” sound above us. Our vehicle was traveling alone in the area at the time, no other vehicles were around ours. There was no debris on the road or flying in air at the time, either. At this point the panoramic roof glass was closed but the interior cloth cover was open and there was no evidence of any damage. When we stopped for gas, the front glass panel covering behind the windshield and before the panoramic roof glass, was completely shattered. The weather was the same as it had been, 80F with minimal cloud coverage. There was no sudden change in weather/driving conditions.

Between [XXX] am on [XXX]. I powered on my vehicle and the rear trunk door simultaneously opened. As I was driving my son to school that morning, I noticed water dripping onto my foot. I continued to drive but was distracted by beeping and warning messages but because the dashboard display was constantly switching from daytime to night lighting I could not readily see the dashboard. I tried to manually adjust the light by turning the knob off "auto" and also turning lights to "off" but it would immediately switch back. I made it to the first stop light and while stopped I was able to observe water droplets on the front panel of the interior fuse box. I pulled open the panel and water dropped out onto to floor. I replaced the panel. I continued to drive but was panicked and worried that water was in the fuse panel area. I arrived at my son's school and left the car running as he was dropped off. On the drive home, the beeping continued. This time, I saw the warning message about vehicle in my blind spot but I was on the street corner about to make a right turn and there was no vehicle next to me! The lights also kept switching as before. There was rust observed in the fuse panel area. When I got home, I called the dealership to inform them what happened. They refused to give me a loaner. I told them that water intrusion should not have occurred (we had severe weather and heavy rains the day prior) and now my car was having electrical issues and I was concerned for my safety an

I am reporting an URGENT REQUEST IMMEDIATE ACTION REGARDING A SERIOUS UNRESOLVED, RECURRING PUBLIC SAFETY ISSUE WITH MY VEHICLE. IT IS POTENTIALLY THE FAULT OF ALEXANDRIA HYUNDAI'S SERVICE DEPARTMENT (in Alexandria, VA) WHO HAD JUST SERVICED MY VEHICLE FOR WHAT SHOULD HAVE BEEN A ROUTINE SERVICING (on May 7). My car had a catastrophic and complete failure on a high speed highway (the car quickly decelerated) which represented an incredibly danger situation for myself and other drivers on the road. My car was purchased in 2023 and has 15,241 miles. It has been perfectly maintained. On [XXX], I was returning to my home in Virginia from Maryland on an 8 lane highway with a 55mph speed limit when I had a very dangerous complete failure of my car. Simultaneously, the car started bucking back, the speed was decelerating regardless of my pressing the accelerator to keep my speed the same as traffic, and I received a flashing large red message that said "CHECK HYBRID SYSTEM - STOP SAFELY." Fortunately I was in the far right lane and was able to veer it over to a narrow shoulder. It was 8pm and getting dark. After a short while, the car lost all power so I was on a narrow shoulder with no lights flashing anymore. I was in this dark car with a lot of traffic speeding my with my 2 dogs. I became incredibly stressed about how we were going to get home. I contacted AAA, a police officer and Uber Pet who worked together in this unsafe situation on the side of the highway to get myself and

I purchased a 2023 Hyundai Santa Fe Hybrid in November of 2023. Within a couple of months of purchase I had 2 incidents where without warning the car lost power and made a noise sounding like some sort of fan. One of the incidents was on [XXX] in Massachusetts, the heavy traffic cleared, I was in the fast lane, and the car would barely move. It was a safety issue as there was no place to go on the left side of the highway and traffic to my right had already picked up speed. After a minute or so the power again became available. This has happened to me several times but Hyundai has told me there is NO RECORD of this happening with my car model. On occasion I have my grandkids in the car and I am very concerned that Hyundai will not acknowledge this problem. By the way, it happened again this morning as I was pulling away from a Starbucks drive-up window. Can something be done about this? Hyundai should have records of my complaints as I visited the dealership where I bought the care and conversed via email with one of their service representatives that I do have a record of. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owned a 2023 Hyundai Santa Fe. The contact stated that his partner was driving at 50 MPH, a light ahead had just turned red, with two vehicles stopped just a couple of feet ahead of her, the contact stated that his partner had proceeded to frantically attempt to brake, however, the vehicle did not brake in time, and the automatic braking assist did not initiate. The complete front end of the vehicle was destroyed, as the vehicle crashed into the vehicle ahead. There was no property damage. The vehicle came to a stop after the crash. The driver's side air bags were deployed, however, the contact emphasized that it appeared the air bag had not fully deployed. The vehicle was towed to a lot. No warning lights had illuminated. A police report was filed. The vehicle was destroyed. The contact partner was injured, and she was seated in the driver's seat, and a single civilian seated in the driver's seat of the vehicle that was hit from behind was injured. The contact stated that his partner suffered injuries to her chest, and the other individual suffered injuries to the neck. Medical treatment was needed for both individuals. The local dealer was contacted however the vehicle was not diagnosed, as the vehicle was a total loss, and the manufacturer was not notified of the failure. The approximate failure mileage was 23,824.

Santa Fe will randomly experience inability to accelerate. I will hit the gas pedal, the engine will rev all the way up to power, it will slowly crawl forward and than violently accelerate. From the time I hit the gas pedal to the time it actually starts moving takes several seconds. It does this every time I come to a stop once it starts. It has done this 4 occasions now. It puts me at significant danger trying to turn across traffic. In general, it not accelerating as you would expect is a very dangerous situation. Dealer has had the car for over a month and has had the car reproduce the issue. The HEV light and check engine light had come on a couple of the occurrences.

As my wife and I were traveling down the interstate at 45 mph, we heard a loud POP, but we were unable to figure out where it came from. Just a few seconds later, the sunroof exploded into a million tiny pieces of glass that partially rained down on our heads and shoulders. It was quite a startling sound. There was a hole about 8 inches across in the moveable sunroof and more pieces were continuing to fall out. To protect our heads, I closed the shade. There was no evidence of an object striking. Windows were all closed when the incident occurred.

Vehicle has gone into limp mode 2 times in the past week. Power when accelerating would not exceed 30 mph when pushing the gas pedal to the floor. Had to pull over as I was getting onto the highway and stop/ power down the car and restart.

Twice, the car refused to switch from EV mode back to gas mode. This resulted in the hybrid battery dying and the car losing power. The first time, I was merging onto the freeway and the gas pedal was all the way at the floor, but I was only maintaining speed (not accelerating). Both times, the car was driveable for approximately one mile on the hybrid battery alone. However, a warning came on the dash, “Check hybrid system. Stop safely.” The second time, I was able to pull into a parking lot before the hybrid battery died. The next day, I was able to drive the car normally. The dealership is unable to pull any codes or replicate the issue. Unfortunately, it only happens intermittently and we have not identified a common theme for the failure.

I am afraid of getting myself or someone else killed because there is a 1-2 second lag after stepping on the gas pedal after coming to a stop. This is extremely dangerous. My street empties onto a county road with a blind curve. I have had several instances when the delay between the car moving after I’ve stepped on the gas has lead to oncoming cars needing to slam on their brakes to avoid hitting me. I even called the county and asked that they put up a “dangerous curve sign. They put up a squiggly arrow instead which has not helped. My previous gas vehicles made this turn safely for 20 years. My nephew told me it’s a new feature in cars called “stop and gol meant to save gas. I think saving my life is more important than saving a little bit of gas. It happens all the time so I will put todays date in the space below.

I have pinging sound coming from the engine when I accelerate. Transmission seems to skip during acceleration. Took it to the dealership for repair since the car is under warranty. Dealership replaced a bearing in the axle and replaced the turbo. I’m still having the same issues. Dealership had my car for 5 weeks dealing with this issue. I feel they don’t know what’s causing the problem.

The Automatic Emergency Braking System, on multiple occasions now, has slammed on its brakes at highway speed when there are no obstacles, barriers, or even vehicles in sight ahead of my wife. This happened to me the other day also when exiting the highway onto an exit ramp when it "Detected Collision" when *nothing* was around me, no vehicles or barriers within any reasonable distance. It's going to end up causing someone to rear end me or her - absolutely unsafe and 100% putting my wife and child at risk. We're taking it to the dealership on Saturday and have verbally informed them of the issue. No warnings, no messages, no nothing prior to incident - the car is practically brand new.

Three times this has happened. The instances occurred on Highway 680 between Pleasanton and San Jose. I was going the speed limit - 65 miles per hour - as were tons of cars around me. Suddenly the car would brake, startling me because I was nowhere near another car. It frightened me a lot! I think it is the automatic braking system - either the front end collision warning or the blind spot collision warning. It could have easily resulted in an accident. I took it to the Hyundai dealership, and they knew they could not likely duplicate it. They showed me where to turn off the vehicle control (braking) for the front end collision warning and the blind spot collision warning. I have read on the Internet several other parties that have experienced this - car-controlled braking while traveling at high speed with lots of cars around.

See attached document for complaint.

Driving down interstate at 70 mph and car started to brake while foot on gas pedal. Would not go…red brake alert came on. Luckily no other car in left lane and pulled off to side of road. Car would not drive. Called tow truck.

It started in April 2024. After the dealership performed an oil change we heard a strange noise whenever we accelerated. The dealership said it was either the transmission or the hybrid motor and both were on back order (usually an indicator that these parts are in great demand). After several weeks both parts arrived but they only replaced the transmission because that took care of the noise. A few days after we got the car back, we heard a clunking sound whenever we shifted. I tried to take the car to a different dealership but they said we had to return to the place that installed the transmission because bolts were missing. We went back to that dealership and they said no bolts were missing but they did need to be tightened. After that the clunking stopped, however, the next day we started experiencing other problems. The check engine and master system lights came on and the car would hesitate when accelerating. This was extremely dangerous when we were on the freeway and/or trying to accelerate from a traffic signal. Also, it had trouble shifting into reverse. The dealership said the codes were indicating the hybrid system battery needed to be replaced. The car has less than 20k miles.

One of the 2 horns has stopped working. After checking the Hyundai Forum website, I've found that one or both horns has suddenly went dead on not just Santa Fe's, but virtually all Hyundai models across the board. This seems to be a widespread defect. This is very dangerous because the cessation of operation is sudden and without warning (ie, no dashboard warning light). If there is a need for the driver to sound a horn in a time of danger there may be absolutely no way to give a warning.

I was driving 70 MPH on highway and the AEB activated despite no other vehicles in front of me. Thankfully the car behind me was far enough behind that they could swerve out of the way, or it could have been a massive collision. Additionally the person behind me could have swerved into traffic Causing a massive accident. This is happened twice the other time I was going 50 miles an hour. I am afraid to drive this car on the highway now.

When I start driving the car if I come up to a hill when I try to accelerate to move forward the cars engine cuts out almost like it stalls. I have to floor or pump the gas which makes a revving sound and the car will go.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving at approximately 30-35 MPH, the vehicle lost motive power. The contact restarted the vehicle and the vehicle worked as designed for several miles before the failure recurred. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the local dealer, where it was diagnosed and determined that the failure was due to the accelerator switch. The vehicle was repaired, but the failure recurred. The contact stated while driving 10 MPH in the driveway, the vehicle lost motive power. The manufacturer was not contacted. The failure mileage was approximately 6,800.

While driving the blind spot safety system, driver attention warning system, and lane following system malfunction at the same time, and the vehicle loses power steering. The first time this occured was in the parking lot of an elementary school in April 2024. I was driving less than 2mph and the vehicle had less than 8,000 miles on it. The dealer said they would be unable to diagnose unless they witnessed the errors. The second time it occured was in May 2024 while driving on the interstate at around 75mph. The vehicle was driven directly to the dealership who kept it for four weeks. They said the connections to the ECU were severely corroded, sanded them down, and added a water protectant. The third time it occured was a month later. The dealership has had the vehicle for two weeks with no diagnosis. Losing power steering suddenly while driving is incredibly dangerous, especially in a vehicle of this size and weight. It is difficult to control the vehicle without power steering, and in all cases there have been other vehicles/people in the area who could have been injured.

I was driving approximately 55 mph on an interstate with no hazards nearby. The car's Emergency Braking System engaged causing the vehicle to slow down suddenly to about 35 mph. I continued pushing on the accelerator to try to get the vehicle back to the appropriate speed and was able to do so.

On highway, emergency braking enacted. I pulled to side the of the road to turn engine off and restart car. When I did, I could not put the car in gear. I have had other similar incidents happen with this vehicle. After about an hour of waiting for roadside assistance and having NYS troopers come help, the car dash lit up and I was then able to put car in Drive. When I talked to dealership and said that I got a diagnostic message on my screen to have transmission component checked TODAY ('today' was in all CAPS on the screen), they said they could not get me in. Then when I said, "I'm supposed to just drive around hoping my car doesn't break down again?" She said, "I'll cross my fingers for you." Are you kidding me!? My safety is at risk is this what a major dealership's answer is to the car's issue?

I was driving on the freeway and there were not any cars in front of me or next to me, and my emergency break went on. My car jerked hard and could have caused a very serious accident if there was a car behind me. This happened two times during the same drive. I took it to the dealer and they told me there was nothing they could do since there was no codes shown. I am very nervous to drive this car now.

As I was driving today my Santa Fe Hybrid lost all power while on the road. The hybrid battery gauge went from 3/4th full to empty in 20 second and I could not get the vehicle to move. Thankfully there was no one behind me and I could safely pull off. When I stopped and restarted the car, the system said ready to drive but the car wouldn't move

Occurred on [XXX] while travelling in the middle lane of a 3-lane highway just west of Raleigh, NC and heading west. The Emergency Brake Light came on, the car stopped suddenly and my head shook from side to side. This could have been a major accident if the traffic wasn’t light. I do not tailgate and there were at least 6-8 car lengths between me and the car in front. No cars on either side. There was no beeping warning from the vehicle about being too close to other vehicles before the car stopped. I pressed on the gas pedal and the car moved forward. The weather was about 50-60 degrees, dry road and sunny. Next Step: Called Hyundai Customer Care on [XXX] and was advised to bring the vehicle in for inspection and correction. Took the car into the Hyundai Autonation dealership in Buford, GA, where the vehicle was purchased. They found nothing wrong. Note: Have researched this problem online and found multiple instances of the same occurrence. See the following online: Emergency Braking System Activates Intermittently | Hyundai Santa Fe Forums INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In a parking lot at a church I slowed down, going 1 mile per hour or less. Upon taking my foot off the accelorator to put my foot on the brake pedal, so I could come to a complete stop, the moment my foot came off the accelorator, the engine reved up and lunged forward at about 10 mph. I was suprised and took an extra second to apply the brakes. In the mean time, my car went over the curb, grass and onto the side walk, a good 10 feet. If anyone had been on the side walk, I would have hit them. Additional information: the transmission was in "Snow Mode", it was snowing and cold outside. Attached photo shows tire tracks of the incident.

4 times there has been an error message with a large P symbol and a red triangle on the dash board. The large P is surrounded by a yellow circle and it says below to check P Button. This is an intermittent situation and does not always do it when at the dealer, BUT they have witnessed it. They tried 2 fixes but neither worked. I am concerned since there is a red triangle at the bottom of the dash that this is a serious issue. Hyundai will not expedite this and will not allow me to speak to anyone about it that might be able to explain what might be causing this issue. Customer service just says we couldn not replicate the problem. I told them I understand this. I WISH to know what is causing the computer to send this message and they will not tell me or look into far enough to determine what it is. I am not driving the vehicle until they can tell me if it is a safety issue or not and they will not do that.

I purchased a brand new 2023 Santa Fe hybrid in August 2023. So far, on four separate occasions (Oct ‘23, Dec ‘23, Jan ‘24, Feb ‘24) I have lost accelerator/gas pedal power while driving down the highway. There is no warning, no lights on dash, nothing. I just all of the sudden lose power. On one occasion in particular, [XXX], I was driving on the highway with my 5 year old in the back seat. I suddenly and totally lost all accelerator/gas pedal power while in the passing lane. I rapidly lost speed and was decelerating with a truck directly behind me and another vehicle to my right in the regular lane. I had to quickly turn on my emergency flashers and pray the truck behind me was paying attention and didn’t hit me. I was jamming up traffic until I was able to get pulled over off the road. My vehicle has been into Hyundai’s garage a total of four times now for the same issue. They have yet to find the root of the problem or fix it. I recently picked up my car on [XXX] from the garage and exactly two weeks later it did it again, this time with my husband in the car so it is once again back in the garage. The last trip to the garage they were able to duplicate the issue but can’t find a cause. Twice my check engine light came on after the fact but only two of the four times. I do not feel safe driving this vehicle but corporate Hyundai did an “investigation” into my case and told me today they found I am not eligible for a refund or replacement and to continue to take it to a ce

Coil failure at 7500 Miles

Panoramic sunroof exploded randomly while driving on 2/8/24. Nothing hit the sunroof it just exploded. Vehicle is less than one year old.

The automatic emergency braking system engaged (the red warning flashed on the dashboard and tone beeped) while I while driving on the highway at 65 mph, in clear weather conditions. This engagement caused the steering wheel to jerk violently left and right, almost causing the car to fishtail on the highway. There was a concrete barrier next to the lane I was driving in, and this was a very dangerous situation. Luckily, there was no car in the lane next to me.

The engine/ability to accelerate seemed to fail. It would not accelerate past 45mph and then couldn't even maintain that speed, even with the pedal to the floor. The engine sounded like it was revving at high RPMs and wasn't shifting into gear, even though it had just been in drive and operating normally. Yes, it is available for inspection. My safety was put at risk by not being able to accelerate when merging onto the highway, leading me to be going much slower than the traffic around me. I have not asked the dealer to reproduce the problem. The component has not been inspected. There were no warning signs, messages, or alerts of any kind. There was no information about the status of the car whatsoever.

Bought the car in July 2023. Nov 23: I had a check hybrid system followed by check engine + red battery warning while driving in the interstate. The car lost power abruptly. Coasted out of the interstate, took the exit, and turned it off. Restarted after 15 mins. Only the check engine light came back on. We drove it back home. Just as we were entering the garage, the sequence happened again: Check Hybrid System warning followed by Red battery warning followed by car losing power. We had to push it back into the garage. Started it two days later and the check engine light was on. Check Hybrid System and red battery warnings did not come back on. Nearby Hyundai dealer's service said that they are not certified to work on Hybrid cars. Hyundai roadside assistance refused to tow it to the dealership that I brought from. So, I had to drive it to the next nearby Hyundai dealer service center who is one hour away. There, the technician ran diagnostics for the check engine light and got an error code: P01E0100. He said that Hyundai's website for running error codes is down. He reset the check engine light and no warnings came back upon restarting the car, so he sent me out. Dec 12: While driving in the residential neighborhood near my home, check hybrid system followed by check engine + red battery warnings came on; car sputtered and jerked and lost power; I did the mistake of turning left to try and bring the car back home; car lost power in the middle of the turn. Fortunately, there

Driving down the highway my sunroof shattered without being hit by anything. Local dealership is replacing, but if sunshade was open glass would have rained down on me.

Vehicle fails to accelerate, engine is “sputtering” and making a rattling sound and battery is draining to nothing on the freeway driving at normal speeds. vehicle is lurching and engine does not appear to be shifting as it should - car losing power and failing to accelerate despite being full of gas. transmission doesn’t feel like it is shifting properly. vehicle only has 8000 miles.

This vehicle has only 8,961 miles. When driving a light comes on that states Check Hybrid System. Stop Safely then the vehicle shuts off. I have taken it to Lester Glenn Hyundai Toms River, where I purchased the vehicle and they cannot figure out the issue. This is a safety concern.

While driving at approximately 70 mphs the panoramic sunroof exploded. It sounded like a gunshot in the car. The front windows were slightly cracked and the rear windows were down for my dog. The sunshade was back to let in light and the sunroof was fully closed. Temperature outside was 60 degrees. I had been driving for 5 hours from southern California to the Phoenix area. Glass went every shattering in the car, so much for shatterproof glass. No other cars were in sight on the two lane Carefree Hwy and no objects hit the vehicle. Sunny but cool day in the desert.

We were driving at around 55mph and Panasonic sunroof exploded as is something hit it: however, nothing did. The glass tattered and fell on top of us (driver and passenger). We were unhurt but quite shook up.

Beginning the evening of 8/21/2023, this 2023 Hyundai Santa Fe HEV began displaying warning messages: "Check Blind Spot Safety System" and "Check Rear Cross-Traffic Safety System." Simultaneously, the car would not register a "Ready to Drive" and could not be shifted into Drive or Reverse. The car could be shifted into Neutral. After turning off and restarting the car several times, the warning messages did not recur, and the car could be shifted and driven normally. The problem recurred in the following days. It appeared that the issue was unrelated to cleaning the sensors but may have been related to the car being left in the sun. The car had to be towed to a dealer on 8/23. This dealer claimed to be unable to reproduce the problem. It is believed that the dealer kept the vehicle in a shaded garage during this time. After retrieving the vehicle from the first dealer, the problem recurred the following day, 9/2, again after having been parked in the sun on a warm day. The vehicle had to be towed to another dealer who was able to reproduce, but not diagnose, the issue. As of 9/18, the dealer states that they have identified a connector that appears to be causing the issue, but they say that they don't know what the connector does, because it does not appear in manufacturer wiring diagrams corresponding to the VIN. Because of the dealer's and manufacturer's inability to diagnose the issue, it is unclear if the issue actually implicates the operation of the blind spot and rear

This tire was observed as defective in an inspection at Holler Hyundai in Winter Park FL. It was supposed to be mailed to Continental Tire for inspection, but the dealership failed to do that. I have photos of the defect (wire protruding for inside side wall). Every effort to discover the tire's location has been frustratingly stonewalled by the folks at the dealership. This tire's lot might be dangerous to other drivers and needs visible inspection.

Since I have had the car, five months, there have been THREE INCIDENTS of the car braking to a stop suddenly and unexpectedly while I am driving. At no time were there other cars near me; I was not in danger of hitting anything or anyone as the road was clear. The stops were jarring and upsetting as I could not discern a reason for these sudden stops. I feel it is very dangerous to stop in the middle of the street without warning.

On 8/14/23/ I got the first oil change for my new car at the dealer. On 8/15/23 as I cruised at 65mph on a crowded Detroit expressway, I pushed further on the accelerator to get away from an aggressive driver on my tail. Nothing happened; The car engine shut down. No warning, no lights, no beeping, no alarm, no dash screen message. Dead engine in the middle lane with cars all around. After i miraculously made it to the shoulder of the freeway, The engine light and oil light came on. Not before, only after the car died. The dipstick indicated The car was out of oil. Unbeknownst to me the parts used to change the oil the previous day were defective. The oil had leaked out over the course of the day and over night. (I later discovered my driveway full of oil). THE PROBLEM, additional to the defective parts is the fact that I HAD NO WARNING THAT THE ENGINE SHUT DOWN WAS IMMINENT. I HAD NO WARNING THAT THE CAR HAD NO OIL. I came close to getting killed that day, and still have nightmares. Had i known the car was oil-less, I would not have driven it. This is a car that beeps and pushes and tells one how to drive at every juncture. It tells low gas, low tire pressure, etc. WHY WOULD IT NOT WARN ABOUT THE LOW OIL OR THE IMMINENT ENGINE SHUTDOWN??? I was told the car has a “FAILSAFE” feature for the oil. HOW SAFE IS A FAILSAFE IF THE DRIVER GETS KILLED WHILE THE CAR ENGINE PROTECTS ITSELF???
