2016 Hyundai Sonata complaints

The engine stopped as I was driving on the road.

My dad gave me his car a little bit ago, and I just learned there is a cap and sensor part in the engine that fills with oil which triggers the check engine light. I nearly got hit because I didn't know the car couldn't accelerate properly when this happens. My neighborhood exits onto the main road at an incline and my car wouldn't move faster than 10 mph while cars were coming behind me at 45. I was terrified. My dad told me had the same problem. He took it to the dealership to be repaired when it happened to him and they said it was fixed, so apparently it is a reoccurring problem.

I am reporting a serious safety concern involving my 2016 Hyundai Sonata Hybrid, which has experienced multiple hybrid system shutdowns while driving. This includes repeated complete power loss incident on I-90 beginning in June 2022, when my daughter was driving home after her hospital shift. The vehicle displayed a “Hybrid System Warning – Turn Off Engine” message and had to be pushed off the highway and towed. This was the first of several hybrid-related failures that culminated in a full engine replacement under warranty at 82,015 miles — and now, the same hybrid system warning has returned at 127,592 miles, well within Hyundai’s 150,000-mile hybrid warranty. Hyundai is currently denying coverage. I am requesting that NHTSA investigate repeated hybrid system faults and warranty denial patterns in Korean-manufactured Sonata Hybrids.

The contact owns a 2016 Hyundai Sonata. The contact received notification of NHTSA Campaign Number: 21V749000 ( EXTERIOR LIGHTING, ELECTRICAL SYSTEM); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Engine its completely shot won't go past 55 mph showing code p1326 knock senor bull crap. Which is the same reason and shows same symptoms as all the other recall 198 engines but hyundai won't cover my model vehicle because its not "part of the recall" when it should be I still owe 10k on my vehicle hyundai quoted me 10k to replace the engine i shouldn't be paying anything due to the fact that yall consistently have to same problems on all your vehicles.

I am writing to formally request reconsideration of a denied warranty claim regarding my [XXX] son's 2016 Hyundai Sonata, which recently suffered complete engine failure and Hyundai has denied. The vehicle is equipped with the Theta II engine, which is widely known to be associated with engine failure risks and is covered under Hyundai’s extended warranty program. Despite this, my warranty claim was denied due to the fact that two recall-related services were not completed. I would like to respectfully challenge this decision for the following reasons: The engine failure is consistent with the known defects in the Theta II engine, which Hyundai has acknowledged through its extended warranty program and recall campaigns. I was not properly informed of the outstanding recalls or their impact on warranty eligibility. We purchased the vehicle in November 2024 and had not received any notifications of these recalls. Had I been made aware of these recalls I would have taken immediate action but again, I was not ever notified. The failure of the engine is unrelated to any owner negligence and should be covered regardless of recall status, especially under a defect-related extended warranty program. The failure has left my son without a functioning vehicle and facing a costly engine replacement for an issue Hyundai has accepted responsibility for in thousands of similar cases. He started working at [XXX] to begin saving for his first vehicle. He spent $8,000 of his own money and is n

Engine failure

While driving my 2016 Hyundai Sonata Hybrid SE (89,000 miles), a “Check Hybrid System” warning appeared on the dashboard, followed by a sudden loss of power. Shortly after, the engine began knocking loudly. A local mechanic scanned the codes and saw engine misfire and hybrid system faults. After clearing the codes, the engine ran worse and the knocking increased significantly. I had to tow the car over 700 miles from Whitehorse, Yukon, to the Anchorage Hyundai dealership in Alaska, which cost me over $5,000. The dealership said they hear engine knocking but refuse further diagnosis unless Hyundai initiates a goodwill assistance case. My car has a rebuilt title, but this issue appears to be similar to other known failures and recalls, such as Campaign 198 / NHTSA 20V746000. It is a serious safety issue — I was stranded in the middle of a remote highway. This appears to be a major defect, and Hyundai needs to investigate and support affected customers.

Steering sticks and releases under pressure at 60/65+ mph on interstate. Very difficult to keep vehicle in lane consistently. Constantly correcting both right & left to maintain straight line is extremely fatiguing especially on long trips. Safe driving at highway speeds is compromised and presents safety concerns for occupants as well as motorists nearby in addition to the apprehension it creates wondering if you're able to correct the steering drift before having an accident. There aren't any dashboard warning indicators when this happens Reported to dealer in central Florida on March 22, 2024 and dealer ordered parts Ref TSB 23-ST-003H. Hyundai Extended warranty TXXO. Factory has sent some parts to dealer twice that I know of and each time vehicle has been taken to dealer I've been told they were not what was needed. On most recent appointment of 12/19/24 I was told the needed parts were unattainable from Hyundai. On 3/20/2025 the dealer has offered to put in some of the parts they have as a possible solution but repair has not been scheduled. Dealer said they had another vehicle that took over a year to repair. This has been 14 months. We're only using this vehicle at slow speeds locally, anticipating complete failure, as we don't trust it for highway use.

See attached document for complaint.

I had engine issues back in 2021. I had to pay $600 for a part to be installed to fix the problem . The engine failed, the idle was violently lurching forward and would randomly Shut down. Recently the car shut down without warning again. Its scary.

Recall on paint quartz pearl white my car is peeling and chipping I notified hyundai because I know many customers also are having this issue and they will not resolve this issue.

My car on the freeway started knocking. The check engine light came on. The car immediately caught fire. It is at the tow yard now. We just went through the oil consumption testing and the cleaning. I filed a report in November it failed for misfire and we paid to have the top rebuild. The car failed the oil consumption 1000 miles after the cleaning. We were told to continue to drive. We had 4 people in the car. I have the dash cam with the rod knock. The car has a check engine code. Hyundai needs to be held accountable.

Oil consumption issues burning oil no leaks.

I just recently purchased about a month and a half ago. I was on my way to work and it was a thudded knocking noise before my car slowed down and shut off on the highway. I had to get it towed to a nearby restaurant I had a mobile mechanic come by he put it on a scanner code p0014 came up with the engine light on.. When he cut the car on and heard the noise he said my engine has failed.. I haven’t had any prior issues with my car before this date.. He mentioned it’s recalls on the engine I have my VIN doesn’t show it’s a recall but it’s the same issues described happened

While accelerating from a red light, the engine suddenly lost power and the car stalled in the left turn lane in the middle of traffic. We had to have the vehicle towed to a repair shop, where I was informed that the engine had seized or locked up. The mechanic mentioned this type of failure can happen if the engine loses oil pressure, but we received no warning lights (oil, check engine, or otherwise) prior to the failure. The vehicle has always been properly maintained, including an oil change just a few months prior, and it had not been driven much since. This vehicle was purchased for my daughter to travel to and from college safely and reliably. We have taken great care of it, so the sudden and catastrophic failure of the engine (without any prior warning) is both unacceptable and devastating to our family and we have no way to get her back to her college. I’ve now learned that this year, make, and model: 2016 Hyundai Sonata has had numerous complaints and issues related to sudden engine failure and oil system issues. To my knowledge, this issue has not been officially recalled, despite a pattern of numerous similar reports. This kind of failure puts drivers and passengers at serious risk, particularly when it occurs during active driving conditions like what happened to us as we were stranded in the road and it almost caused a vehicle to hit us. As a parent, I entrusted Hyundai with my family’s safety. I am extremely disappointed by what appears to be a systemic issue a

Tengo este sonata ya 3 años a solo un mes de haberlo comprado empezó con los problemas de check hybrid system todo el tiempo el mecánico no sabe que pasa con eso además siempre cuando se enciende esa luz no se puede manejar el carro y le dice que tengo que apagarlo

Sometimes I see the engine ligth when I drive to long

My vehicles engine gave out on highway 95 . I towed it to the Hyundai dealership after a mechanic friend informed me of the recall with the Sonata Engines. Hyundai is refusing to assist with my engine failure under the recall or my lifetime warranty. They are stating that the recall is voided due to my dipstick size and that my lifetime warranty on the engine is voided due to another safety software recall not being updated before the engine recall; I was not informed by Hyundai of either recall. I am now without a vehicle

THE ENGINE THEY EVEN HAVE A RECALL ON MY CAR ENGINE THIS HAVE CAUSED NO RISK THIS PROBLEM HAVE BEEN CONFIRMED BY A MECHANIC HAVEN’T BEEN LEGALLY INSPECTED YES THE OIL LIGHT COMES ON OFTEN

I am reporting multiple safety-related problems with my 2016 Hyundai Sonata Sport 2.0 that have become progressively worse and may pose a serious danger. The Electronic Stability Control (ESC) warning light starts blinking during startup, then remains solidly illuminated while driving. This indicates a persistent fault in the stability system. The car also frequently slows down or brakes on its own, without any input from me. This happens especially right after starting the car or while driving in traffic, and has caused multiple near-accidents. These issues first appeared around two years ago, but they used to happen occasionally. Over time, they have become more frequent, and now they occur daily. There is also a grinding or dragging noise when the vehicle starts or moves at low speed, and it often hesitates when trying to accelerate. These symptoms create uncertainty and make the vehicle feel unsafe to operate. Inside the car, the dashboard has severely cracked, with deep, wide splits across the top panel. I’m concerned this could interfere with airbag deployment or reflect light dangerously while driving. On the outside, the paint is peeling off in large chunks, and I’ve noticed the same problem on other Sonatas of this model. This suggests a wider manufacturing issue and raises concerns about long-term durability and corrosion. These problems have not been confirmed by a mechanic yet, but they are consistent, worsening, and clearly pose a safety risk. I have recorded a v

Extremely well maintained car began burning excessive amounts of oil. Called Hyundai corporate and they said that there is an extended 150,000 mile warranty on the engine and set me up with the Metrowest Hyundai dealership in Framingham, MA to begin oil consumption test procedure. Dealership performed test and I burned almost 2 out of 5.1 quarts in 1,000 miles. There is no reason a well maintained engine, with regular oil changes well within the manufacturer recommended interval and using full synthetic oil, coupled with regular engine maintenance and Techron, plus at least 80% highway miles, should be doing this. Dealership then performed combustion chamber clean as step 2 of process and the entire timing system began failing after that (P0010 and P0011). The car is now at the point of almost catastrophic engine failure and it will cost $6,200 to repair (the value of the car itself). Hyundai corporate then told me I'm actually not covered and that the warranty only covers rod bearing failure. So both they and/or the dealership strung me along, and the car is clearly not made well and Hyundai is not addressing these concerns. I know many people have had these issues with these cars. In my case, trying to get them addressed then destroyed my car.

Hello this is my second time filing for a complaint because the first time I did not receive an email confirmation. On Thursday night (April 4th) I was driving back home, I had just existed the highway and was now on a regular big busy street. I was driving approximately no more than 25 MPH. At the traffic light when it turned red I obviously had my foot on the break. When it had turned green and I tried to accelerate the car would just not simply move. As I said I was on a busy street there was many cars, My partner and I had to safety move the car by foot out of the road to let other cars pass, it was very dangerous for us since it was at night. I'd like to add prior to this the only time I ever had a problem was when I would turned on the car and later try to drive it would start shaking for a minute and then suddenly stop when I parked it and turned it off. Also there was never any engine light or any warning lights on the dashboard, To continue I had to call my dad late at night to help me find what was wrong with the car, obviously since it was at night there was not much to do, but to park the car and leave it there overnight. Next morning he goes and try to see if it turned on, It didn't the car was not running anymore, he called a tow truck for them to take it to a mechanic, In where they said it was an engine problem. The mechanic told my dad it would need a new engine which that can cost a lot. I called in the dealership in where i am financing it and told me if it

Car keep stalling misfire just started muffler sound smoke lack of power when driving

Driving back home [about a 20 min ride] car has been driving fine, with no lights on dashboard EVER showing , obviously on a red light i had the break, then when it turn green the car would not accelerate at ALL. Car was still on with light and radio working the car would just not accelerate. I was on a busy street so I had to push the vehicle by foot with my partner to get it out of the way. Oil and battery seemed fine, I had to call my dad for help he as well did not find anything. We had no other choice but to leave the car on that street parked. Next morning my dad went to check it out and the car would not turn on AT ALL. He called a towing truck and took it to a mechanic in where he said that it was in fact the engine. When driving and prior to other cars I've driven the car there was never a warning sign what so ever this came out unexpectedly, putting my partner and I at risk in a busy street having to move the vehicle by foot.

After having the car for about a week the engine light came on at that time I took the car back to Carmax Service Department in Canoga Park. They scanned the car and they told me that it was misfiring. Carmax fixed the car. They had the car for the ten days. The day I received the car back, the engine light came on again. Took the car to my mechanic and he ran the codes again and he told me it was misfiring, again. He cleared the code and I again returned the car to Carmax, and explained to them what happened. I checked on the car couple days later and I was told that they drove the car for 30 miles and the engine light didn't come on. I picked up the car the next day On [XXX], the engine light came on, again. I returned the car back to Carmax, April 1st and talked to the Service Manager. I explained to him everything that happened. In each case, before returning the car or having the inspected, I did notice a difference in the way the car responded. Also, when I filled up with gas, the gas didn't fill up all the way and there was a clicking sound when driving.

The contact owns a 2016 Hyundai Sonata. The contact stated while the vehicle was parked, the contact noticed that oil was leaked underneath the vehicle onto the ground. No warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 59,868.

I am reporting multiple serious issues with my 2016 Hyundai Sonata Sport 2.0, which has only 30,000 miles. Despite the low mileage, the vehicle is experiencing major safety and quality problems. The Electronic Stability Control (ESC) light stays on constantly, indicating a system failure. On startup, the car sometimes applies the brakes by itself, and there’s a loud noise like something is stuck or grinding. The traction control light also comes on during this. While driving, the car will suddenly slow down on its own, even when I’m not braking. When I press the gas pedal, it barely responds or takes too long to accelerate. Sometimes, this happens at the same time as the ESC warning, which feels extremely unsafe — especially on highways or in traffic. The push-to-start button often delays before the engine turns over, which is abnormal. The A/C system only blows warm air, regardless of temperature settings, and no cold air comes out. I also have a serious issue with the paint peeling off in large chunks from the body of the car. It’s happening despite proper care, and I’ve seen other Hyundai Sonatas of the same year with the same issue, which suggests a widespread paint defect. These issues have not yet been diagnosed by a dealership, but given the low mileage and frequency, I believe this model may have serious defects in safety systems and paint quality. I’m very concerned for my safety and request a full investigation.

The fuel pump where the fuel line connects to it is cracked and squirting fuel all over that area. Some time ago I started smelling fuel when getting close to the vehicle or when opening windows. Took it to a shop to have it checked out and the technician couldn’t find the problem, since there is no check engine light on or any type of warning. A few days ago I decided to check the bottom part of the fuel tank and noticed that there were traces of leaking fluid. Reached to it and checked it closely and certainly was fuel dripping. Checked the top of the tank where the fuel pump is and found out that the problem was there. Did some research online and found out that that’s a very common fail. I Would like to have it investigated and recall all those failing cars for my safety, my family’s safety and everyone else that trusted this company and is letting us down. First time I noticed this was back in 2022 and is when I took it to the shop.

After driving for a few minutes with the sunroof open the wind deflector pulled and nearly off the car. This had been repaired previously under a recall and the repair was simply to re-glue the wind deflector back in place. This had clearly been done before as the dried glue was still on it. The back end of the sunroof nearly came off during this ordeal while we were traveling at highway speeds and it could have killed someone. We were able to close the sunroof once we had stopped, however it was very difficult to do so and required four of us, each with tools that I happened to have in the car at the time. Had we not been able to get the sunroof back closed it surely would have been ripped from the car. Another recall needs to be put into place and an improved correction needs to be put into place.

What component or system failed or malfunctioned, and is it available for inspection upon request? Engine How was your safety or the safety of others put at risk? I was driving 60 mph down a busy highway when I lost the ability to accelerate—putting myself and others at risk while trying to get off the road to a safe location. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? Yes. A mechanic that has been in our area for decades. Were there any warning lamps, messages, or other symptoms of the problem before the failure, and when did they first appear? No.

The contact owns a 2016 Hyundai Sonata. The contact stated while driving 35 MPH, the accelerator pedal was depressed, and the vehicle failed to respond. The TPMS warning light was illuminated. The contact stated that while driving around a corner, the vehicle started losing motive power. The contact continued depressing the accelerator to the floorboard; however, the vehicle failed to respond. The contact pulled over to the side of the road and the engine seized. The check engine warning light illuminated. The vehicle was towed to an independent mechanic where it was diagnosed with bearing failure. The contact then towed the vehicle to the residence. The dealer was not made aware of the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 144,336.

The engine violently vibrates and no matter how much I get an oil change it burns so fast and I have to keep adding. It's not leaking, just burning. I plugged in a diagnostic tester and it said that the 3rd cylinder was misfiring. I haven't had the car for very long, and this is not normal. I take good care of it.

My vehicle had the following symptoms: 1. Alternating between sluggish acceleration/handling AND rough acceleration with the vehicle lurching forward at times 2. Check engine light with error code P00010 3. Occurred frequently over a one month period (5+ times) This was unsafe as the car could not properly accelerate and would lurch forward at intersections. This could easily have led to a crash. We limited driving. This issue was observed at the dealer where I repaired issue. The issue is exactly the same as the issue described in the recall for Hyundai Sonata 2015 under SB-10058136-4434 and was resolved by replacement of the E-CVVT seal as described. This issue is ridiculous for me to deal with and put my family as risk given it a KNOWN issue for Hyundai in their other vehicles.

The contact owns a 2016 Hyundai Sonata. The contact stated while driving 50 MPH, the check engine warning light illuminated. The contact smelled burning engine oil coming from the engine. The vehicle was taken to the dealer to be diagnosed. The contact stated that a friend arrived at the residence to inspect the vehicle. Upon inspecting the vehicle, the friend became aware that oil was leaking from the head gasket. The contact stated that the friend used an ODB scanner and retrieved DTC: P1326. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 20V746000 (ENGINE); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 135,558.

The contact owns a 2016 Hyundai Sonata. The contact stated while reversing, the vehicle was shaking abnormally. The contact stated that the check engine warning light illuminated, and engine oil was added to the engine. The contact stated that the failure was like NHTSA Campaign Number: 20V746000 (Engine). The vehicle was taken to the local dealer, where an oil consumption test was performed, and it was determined that additional testing was needed and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was unknown.

Car Lost Power going up a hill. Generating codes P1326, P0455 and P0302

I was driving a 2016 Hyundai Sonata on a mountain highway and it started to run rough and lose power dramatically when accelerating. A dangerous situation on a steep curvy highway that has many one lane sections. Shortly thereafter a dash light came on. There was no warnings or dash lights or symptoms prior to this incident. I took the vehicle to a mechanic and ran the code. It said there was a misfire in cylinder 3. Replaced the ignition coil and spark plug for cylinder 3 and it did not fix the problem. The mechanic then pulled the motor to check the valves. Valve 3 was burnt, had a hole and stuck open. The car had approximately 75,180 miles. Well within the warranty time frame of 10yrs or 100,000 miles for an original purchaser. The mechanic had the valve machined, and replaced the head gasket and reassembled the the motor. I picked the car up and drove it home. Within 3 days I noticed an oil leak under neath the car where the engine bay is. I took the car back to the mechanic and he diagnosed a hairline crack in the oil pan. After some research I came across a letter from NHTSA on a defect investigation of Hyundai/Kia oil drain pan assemblies. This is exactly what happened to my car! I have paid 3500.00 to fix a car that has less than 76,000 miles. Hyundai needs to do better.

The contact's daughter owns a 2016 Hyundai Sonata. The contact was informed by her daughter that while driving at various speeds, the vehicle was shuddering significantly. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that there was oil leaking onto the spark plugs and causing the spark plugs to short circuit. The dealer replaced the park plugs several times; however, the failure persisted. Additionally, the contact stated that the vehicle was experiencing excessive oil consumption. The vehicle was taken to the dealer several times, where an oil consumption test was performed, and the dealer confirmed that the vehicle was experiencing excessive oil consumption. The contact stated that her daughter had received an unknown engine recall notice, which the contact related to the failure. The vehicle was not repaired. The contact stated that she was concerned for her family's safety. The manufacturer was notified of the failure and several cases were filed; however, no further assistance was provided. The failure mileage was approximately 88,000.

While driving, the vehicle's engine light will randomly turn on and when it does, the car will lose power; meaning, when this occurs, and I press the accelerator pedal, it does not put out the normal, expected amount of acceleration. This problem will persist until I pull over, turn off the vehicle, and turn it back on. However, this does not always fix the issue. Sometimes, when I turn the car off and turn it back on, the check engine light will still be on and I will still encounter the issue. When I brought my vehicle into my local Hyundai dealership, they had the car for 3 days, and when I called to ask what was wrong with it or what they did to fix it, they told me they could not recreate the problem and therefore, did not do anything to the vehicle. So now, I'm at an impasse where this problem is not able to be recreated, thus, unable to get it fixed, but I don't feel completely safe to drive long distances. I also own a 2013 Hyundai Sonata that experienced the same type of issue, and that engine was recalled.

Been fighting with Hyundai for quite sometime to have engine repaired due to excessive oil consumption and other issues no matter what you take it they state it’s normal for you to apparently run out of oil before oil change is due. These engine are pure junk and they go out with any warning whatsoever forcing customers to foot the bill for a new engine. They absolutely do not care. I highly recommend any does not purchase Hyundai or Kia. Now that my engine finally went out they expect me to pay over 9000 for a new one when I repeatedly told them my concerns ahead of time trying to avoid this.

My car burns through approximately 1qt of oil every 500 miles or less. There is a known oil consumption issue and I have left multiple messages with Key Hyundai of Milford CT and do not receive a call back. Additionally today I was driving 25mph and my car was reading 4000rpm and then completely locked and shut down I was stuck in the middle of the road.

Hyundai Motor America (HMA) denied my engine replacement claim (PA# [XXX]) under their extended warranty program, specifically campaign TXXI. This claim involves my 2016 Hyundai Sonata SE 2.4 , VIN # [XXX] , which exhibits all the symptoms and engine damage outlined in the campaign, yet my request for a free engine replacement has been unjustly denied. Campaign TXXI, as explained in the Technical Service Bulletin issued by Hyundai, extends the engine warranty applicable to 2015-2019 model year Sonata (LF) vehicles equipped with Theta II 2.0L Turbo and 2.4L GDI engines. This warranty covers engine long block repair or replacement due to engine damage or malfunction from connecting rod bearing wear and extends to a Limited Lifetime Warranty, valid for both original and subsequent owners. o On or about [XXX], my vehicle exhibited a blinking check engine light on the dash, entered into limp mode, and a knocking noise was coming from the engine. o As I was driving the vehicle to the Hyundai of North Miami Service Center on [XXX] (21400 NW 2nd av., Miami, FL 33169) for inspection, the engine locked up and stop, necessitating a call to a towing truck company to complete the trip. o Upon inspection, the service center identified significant engine damage, including, engine mechanical failure unable to turn on, and recommended that the vehicle require a new engine replacement. o These findings align with the engine damage described under campaign TXXI. o Despite meeting the campaign c

Vehicle has been repaired due to broken valve. Vehicle was unsafe to drive. Valve burnt at 70 mph. Car threw misfire code P0303 and started shaking. This issue could have caused an accident. Valves were replaced at Young Hyundai in Ogden Utah. Valves were not covered under the lifetime rod bearing recall. Several people have had this failure on the Engjne issue group page. I have a photo of the valve. It is missing a chunk of the valve head. That piece was not located during the valve rebuild. The vehicle had 116,000 miles at time of failure and is consuming 1 quart of oil every 500 miles.

Wind deflector came loose on highway after recall was performed. The wind deflector was originally reattached in 1996 shortly after purchase. The recall doesn't take into account that the manufacturing issue may of been previously repaired. I believe when the "recall" was performed(2020) the lack of removing the previous adhesive created a weak bond enabling the wind deflector to become detached. Attached is a copy of the recall instructions which contains no step to remove previous adhesives or check for previous repairs; only the use of alcohol to remove dust or particles. Hyundai corporate followed through on an investigation Case Number #[XXX](December 2024) finding that the recall was performed and they had no ability to investigate the proper method for subsequent repairs. Referring the issue back to local dealerships to apply their own judgement. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2016 Hyundai Sonata. The contact stated while starting the vehicle, the driver's seat belt became inoperable. The contact stated that the seat belt failed to properly retract or properly restrain the contact while driving. The vehicle was taken to the dealer where it was diagnosed and determined that the seat belt assembly had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 66,800.

This event took place on or about [XXX]. A month or two prior, my vehicle had just undergone a safety inspection with over $2,000.00 worth of repairs that were performed with great care, due to noticing loss of power upon acceleration. I'm currently living in Wyoming, and the engine blew while driving on the highway in Colorado, causing a mild underbody fire while driving at high rate of speed. At this point, my safety is of great importance and concern, the radiator had internal damage that was not disclosed by the initial dealership, that took possession of my vehicle. So I truly don't know what or who to believe (which parts have been properly repaired on my vehicle or what has not), it took me to personally tow my own vehicle back to the local repair shop here in Wyoming, and the repair shop could not get power to the vehicle. Eventually the repair shop realized that the original "ground" bolt that "was" on my brand new battery was stripped out of place and replaced with a tapping screw, that's why no power was getting to the vehicle as needed to operate properly. The repair shop also noticed internal damage to the radiator (inside bay) with 2 puncture holes (that was not disclosed at any point of interacting with the dealership. Now my safety is an extremely huge concern. Again, I don't know if the vehicle is in worse or better condition with the most recent repairs that have been done to my vehicle. The engine was confirmed to have been damaged internally and externally

The contact owns a 2016 Hyundai Sonata Hybrid. The contact stated that while operating the vehicle, the parking brake light remained illuminated. The vehicle was taken to the local dealer to be diagnosed. The contact was informed that the ABS control module was faulty and needed be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 149,000.
