2020 Hyundai Tucson complaints

MOTOR IS CONSUMING A LOT OF OIL. I need to CHANGE EVERY month, which IS VERY EXPENSIVE

When driving my check engine light started to blink and my car would not accelerate. I made it home and plugged in a diagnostic reader and got the code P1326 glow relay short circuit. My car along with my friends 2021 Hyundai Tucson both have this same issue. There needs to be a recall for these years. There is a recall out for this specific problem in sonatas and Tucsons and need to cover these years as well.

Excessive oil consumption. Confirmed by Strickland service centers on last 2 oil changes. Engine is at risk of failure if oil level drops.

Car is burning through oil at a rate of 5L per week.

Car broke down first time about 2.5 months ago. It was towed to Fred Beans Hyundai of Doylestown PA and they did oil testing on it and I was told that the car was burning oil too fast. They told me under warranty they needed to do a carbon combustion cleaning. So that was down, and less than 24 hours of having the car back, the check engine light came back on, the car wouldn’t drive above 50 miles per hour, and was jumping forward (the same thing that happened the first time) I had the car towed back to the dealership and they told me there was still leftover carbon and it needed to cleaned out again. The car was fine for about 2 months, however just today it broke down again. Same problem, check engine light came on and started flashing, the car will not go above 50 MPH and it jumps forward. I have now been given back a car that is unsafe to drive and put my family and 2 times. Clearly the dealership is not fixing the actual problem at hand and continues to put my family and i’s safety at risk. Each time the car has broken down I have been on the pa turnpike and been put in an extremely dangerous situation.

The contact owns a 2020 Hyundai Tucson. The contact stated that the "Check Brake Light" message was displayed on the instrument panel, and the screen indicated that the rear brake light bulb was defective. The vehicle was initially taken to an independent mechanic where the brake light bulb was replaced; however, the failure recurred. The vehicle was then taken to a dealer where the contact was informed that the brake light bulb had failed because the bulb was an aftermarket part. The contact had the brake light bulb replaced with an authorized Hyundai part; however, that part also failed soon after the bulb was replaced. The manufacturer was notified of the failure and referred the contact back to the dealer for assistance. The vehicle was taken back to the dealer but was not yet repaired. The failure mileage was approximately 40,000.

The contact owns a 2020 Hyundai Tucson. While the contact’s daughter was driving at an undisclosed speed, there was an abnormally loud knocking sound coming from the vehicle before the engine seized. The vehicle was towed to the dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 83,500.

High oil consumption. Car shaking , sputtering, Shutting off in traffic. Replaced spark plugs 3 times in a year. Having to top oil off every other week because there will not be any oil in engine. Stopped in traffic.

Engine is consuming 3+ quarts per 1000 miles. There is no low oil warning light or notification, just a low oil pressure light which could be caused by many things that would not cause a vehicle fire like low oil would. Hyundai was contacted and we were told that all we need to do was get our oil changed with them, come back in 1000 miles to check the level, if it was consuming greater than 1 quart per thousand miles we would be scheduled for a combustion chamber cleaning (service tech said this would do nothing to solve the issue), drive 1000 more miles and check level again, and if it was greater than 1 quart per thousand we would be scheduled for a new engine. They were informed that we were the second owner and we were told that shouldn’t be an issue. After completing the oil change and going in after 1000 miles we were told that the engine consumed approximately 3 quarts of oil. That information was apparently submitted to Hyundai and they said we were not approved for the combustion cleaning because we were the second owner. The safety of the vehicle was not taken into account at all and Hyundai did not show any concern of vechile fires even though low oil is a contributing factor to many scenarios that can cause injury or death.

The contact owns a 2020 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The contact stated that several unknown warning lights were illuminated. The contact was able to pull to the side of the road. The contact called a towing service to jumpstart the vehicle. The vehicle failed to restart. The vehicle was towed to the dealer where it was diagnosed that the crankshaft bearing failed due to foreign material in the engine and oil consumption. The contact was informed that the engine needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was not made aware of the failure. The failure mileage was approximately 122,000.

Excessive oil consumption in the engine. 1 Qt every 900 to 1000 miles. This has been going on a while.

Car had check engine light come on and found out that it had been using oil. Engine started using more than 1 quart of oil every 1000 miles. Catalytic converter had to be replaced because it was plugged. Car had less than 80,000 miles on it when this started happening.

This call actively has a recall on engine rods any Hyundai and some Kia models ranging from 2011 all the way until 2022. They are known for having a faulty motor with active oil consumption and are currently facing several lawsuits and my car is one of these cars facing this issue however, the manufacturer doesn’t want to Fully create a recall on the motor claims that are causing this rapid oil consumption issue I would like this to be investigated as well as it be investigative why you don’t already have their current active recall listed on your website . but if your website was correct and listed the engine, Roddery call, and if my engine rod were to blow, then they would actually address this issue however, some people are getting this issue addressed under their manufacturer warranty however it is becoming extremely difficult because they want us to pay out-of-pocket for a pointless test as newer vehicles should not be burning oil with no active problems. Clearly, the states there is a problem which there is as of all the active lawsuits.

At times, this vehicle will refuse to go. You will get an alert in the dash that the emergency braking system has engaged. It may be a door is not completely shut, or sometimes it's just that I don't have my seat belt on. It seems to be inconsistent, because I often times put my seat belt on after I finish backing out, and am ready to go forward. If there is any kind of incident that requires a fast escape, this "feature" could cost somebody their life, or cause them to deal with a carjacking. The car needs to go when I tell it to go.

Excess Oil consumption cause the engine to die and the car to stall out in the middle of the road. Engine needs completely replaced.

This engine been consuming tons of oil in it and I keep having to add more oil to it and it doing same thing with the coolant causing the engine to heat up a lot and smoked too

The contact owns a 2020 Hyundai Tucson. The contact stated while driving at various speeds, the vehicle stalled and failed to accelerate while the accelerator pedal was depressed. No warning light was illuminated. In addition, the contact stated that the A/C was blowing warm air. The contact lives in a hot climate and was concerned for the safety of her 2 minor children. The contact stated that on three separate occasions, three A/C compressors were used to attempt to repair the vehicle at a service center however, the failure persisted. The vehicle was taken to a local dealer where it was diagnosed at the owner’s expense due to the warranty being invalid. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 20V543000 (Service Brakes, Hydraulic). The manufacturer was not made aware of the failure. The failure mileage was approximately 30,000.

The contact owns a 2020 Hyundai Tucson. The contact stated that while reversing, the brake warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the brake light needed to be replaced. The independent mechanic informed the contact that the brake light housing case had melted. The dealer was contacted to purchase a new housing case. The contact purchased the part, and the vehicle was taken to the independent mechanic and the vehicle was repaired; however, the failure persisted. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.

The oil pump failed, causing the car to die while on the interstate. There was no prior signs nor warnings to this issue, and it caused the engine to lock up, meaning that the engine now needs to be replaced. This is not unheard of with Hyundai’s.

2020 Hyundai Tuscon engine continually consumes an excess amount of oil on a weekly basis causing cylinder knocks. This vehicle has been routinely maintainanced and continues to experience this issue which is an issue known by the manufacturer and has yet to be addressed seriously by the manufacturer. The vehicle is just out of warranty; however, the issue stems from known engine faults that are the responsibility of the manufacturer.

The check engine light became flashing and the vehicle went into limp mode while occupied by two adults and one minor child as they were merging to access the freeway

For about three weeks, my airbag warning light appeared intermittently, lasting 1–3 minutes at a time. I have not taken it to the dealership because I was unsure if it was covered by the warranty, and they had no availability. Now the warning light is off, but I am worried that the airbags will not deploy if needed.

Our daughter was notified by another driver at a stoplight that her brake lights were not working. The car's brake sensors indicated the brake lights were not working, while driving the light went off and the lights worked again momentarily. The Hyundai dealership refused to address the problem when it was taken in for maintenance because the light did not appear for them they said it wasn't possible to a fix it. After an online search, there are instructions on what to do if you are a DIY person. They are very basic if you know your way around the electrical system in the auto. Our daughter lives and works in the Phoenix metro area putting her at risk from collision and being in violation of local ordinance regarding vehicle operation. There were no earlier indications of a problem until 5 days ago.

I went to Thompson Automotive to finance a vehicle and within a month and half my engine blew. There were no engine lights, no lost of oil, no warning, no signs of any error, before this series of malfunctions took affect. I was on my way to the dealership and my car being slowing down to a complete stop as I was getting off the highway ramp. I was traveling at the speed of 25mph, when the car started to make loud noises that I never heard before that day, and completely shut down in front of a huge tractor trailer in traffic. The dealership has had my car since 6/7/24. Now the car has about 85,000 miles on it. I have to pay another $3,000 for my portion to get a new engine. Which is outrageous considering I just agreed to pay $19,990. I am highly disappointed that I lost my job and everything behind this horrific situation that actually feels like a set from the beginning. Now that I’m reading all the comments and unfortunate but very similar situation everyone is suffering from with the particular car. I can’t fathom why it’s still on the market to be purchase for consumers with these major and potentially deadly problems.

I was driving 45mph on a major road when, the vehicle with out warning lost power, I heard rattling, lost power. I turned it back on by the power button, drove into gas station where the check engine light flashed, oil light flickered and didn't turn back on. Car was rattling, turned it off. Got out, checked engine under hood and components. Dip stick had oil. Car had no signs of anything else. Vehicle would not start, called tow. Waited 5 hours for tow. Did not hear back from Hyundai dealership in a month. Submitted all articles of maintenance. Going on two months and was told to resubmit. Three months prior, engine over heated due to original hose component coupler piece melting.

Check engine light came on and went off again prior to waiting the 2 weeks for service. Infamous code P0420 catalytic converter bank 1 code where manifold, catalytic converter, and O2 sensor were replaced at a measly 37k miles.

This is the second Hyundai Tucson that I have owned and the same thing has happened wih both of them. My daughter also bought her Hyundai Tucson the same day as I got mine in June, 2020, and the same thing is happening to her. It starts with the engine warning light coming on, and then finding that the engine oil is low in between oil changes. There is no visible sign of the oil leak (no drops on the driveway, no oil in the engine compartment, etc.) but now the oil is disappearing at an alarming rate. My daughter has had her car looked at, and it appears that she may have to get a new engine, which is what happened with my previous Tucson (2015). Luckily, Hyundai "good-willed" me the replacement of my previous engine, but now I am at, or close to the limit on my extended warranty (for which the dealership did not give me paperwork), and have an engine that is just disappearing engine oil. Hyundai has to know of the issue, but refuses to make corrections to the problem which sticks people with huge bills to correct a problem they know exists. I have seen MANY complaints about this exact thing, so it's not a secret.

When driving this car it is hard to go to higher speed. Acceleration is a huge problem. Coming on to the highway I have to wait until there's no one approaching due to the fact that it takes about 40 seconds to a minute for the car to accelerate once it comes to a stop. When switching lanes it takes 40 to 60 seconds to accelerate as well. That's not safe. God forbid someone was speeding directly behind me I would absolutely be hit. It takes to long to accelerate and get out of the way. I was nearly hit by a semi truck due to this problem. Thank goodness the truck moved to the other lane because the Tuscon couldn't! Also the car won't allow you to close off the outside air while if the front or rear air function. So if I want to place air on the windshield I have to breathe in the air from the person in front tailpipe. That's crazy. This is the first car I've had that did this. It's disgusting especially living in ny why should I have to breathe in that toxin. Also I can not find the third seat belt for the passengers in the back. The car is suppose to be a five passenger car however only four can safely be seated.

On 8/7/2024 the engine light came on and stayed on. I took the car to my service pro and he did a pcm scan. Error code displayed a catylitic problem on bank 1. This is the secind time this has happened to this vehicle. First time was 2/13/2023, Mileage was 52000 miles. Salem Hyundai replaced the Cat with a new one. On 8/8/2024 I called Salem NH Hyundai to report the issue and have an appt for 8/14/2024. Milage on vehicle is 77181.

While driving the vehicle suddenly started alarming indicating to check "Forward Collision Warning" followed by an alert to check "Lane Keeping Assistant." Immediately pulled off the road shut the vehicle off and checked the perimeter. No issues noted. Issue continues, while waiting for service from local dealers.

Had for a year. 6 months ago, started sputtering, surging, slowing and dying on a regular basis. Have had it shop at Chapman used in Tucson, AZ and Lawley Hyundai in Sierra Vista Arizona 3 times. Chaan couldn't repair, so we went to Lawley. The mechanism there keep saying they cannot reproduce! The engine malfunctions 3-4 time during any drive we do. Has been going on for 6 months.

Electrical rear brake system. My rear driver side brake like sometimes fails to operate properly. Brake warning light on dash comes on. This happens on and off. After researching the issue I found numerous owners are having the same issue. Some replace the bulb multiple times while others have had dealerships replace the harness. Both solutions only temporarily fixed the problem for a short time

The vehicle is a 2020 Hyundai Tucson with AWD. Current mileage of the vehicle is 58,309. In the last 10K miles, there have had 4 separate instances of a sustained flashing check engine light that has put the car into limp mode. Since the first instance, a knock sensor, catalytic converter, and spark plug coil, among other things, have been replaced. However, the issues persist and have yet to be resolved. The engine continues to misfire, resulting in dangerous driving situations. Most recently (XXX) the car went into limp mode on an interstate highway where the vehicle was unable to accelerate and could not exceed 2000 RPMs. The code scanner read P1326 - Glow Relay Short Circuit. This was just a week after the vehicle was towed to McGovern Hyundai in Brockton, due to the car being in limp mode (XXX) and the vehicle was given a clean bill of health. I was told that there was no cause for concern and the code was cleared. I’m extremely concerned about this issue with the vehicle and don’t feel that it is safe to drive, especially when it loses power on the highway. The vehicle is insured, but has not been inspected by an insurer. Nor has the vehicle been inspected by police. The car has been inspected by the dealership, but that have not produced any findings. The car is certainly available for inspection upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2020 Hyundai Tuscon May I have had numerous incidents where my stereo navigation screen goes black, and then instantly comes back. This happens frequently; whether or not my phone is plugged in. I have stopped plugging my phone into the car. May 1, 2024 As I was backing into my garage this afternoon I started the turn to get into my driveway. I turned the steering wheel tight and it seemed to lock up just like the car had turned itself off. My vehicles main screen went blank along with the stereo navigation. May 16 2024 As I backed into my driveway and straightened my steering wheel position to get into the garage the vehicle screen went black along with the navigation stereo screen I felt the steering wheel tug a little bit along with a knocking noise All lighting quickly came back and then the same exact thing happened again. I then finished backing in and turned the car off. May 18 My husband and I went to the market 1 mile away and as he was backing into the driveway at home the steering wheel locked up then the stereo navigation screen went black and we heard bumping sounds same as before. This happened numerous times in a row going in reverse and forward and we were able to get two videos. After we got the car parked in the garage we tried to open the back hatch to get the groceries out and we were unable to do so manually or with the key fob. At that time, we then noticed that the entire electrical system was down. I then sat in the front seat, tried to turn the car on

The contact owns a 2020 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle independently decelerated. In addition, the check engine warning light was illuminated. The vehicle was towed to the dealer where it was diagnosed with a knock sensor failure. The contact was informed that the knock sensor needed to be replaced. The vehicle was repaired. The failure reoccurred. The vehicle was towed to the dealer where it was diagnosed with a failed engine and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 101,196.

I was driving home last week when I came across a large crash on the highway. Traffic was backed up for a mile. I decided to turn around through one of those crossovers and head a different way home. I accelerated to catch up to the oncoming traffic when my car suddenly sounded more loud like it was struggling to accelerate. I got onto the off ramp and my car slowed from 70mph to 40mph and would not go any faster. It began lurching and I decided to try to get off the highway and get as close to home as I could as it was 9pm. My car slowed to a stop and the oil light and engine light and battery light came on. A few moments later the whole dashboard lit up and the car died. I popped the hood and to my horror there was literally no oil in my car. My oil light never came on and my oil change service notice never came on at any point. I took it to a dealership where they told me my engine has blown and needs replacing. This engine experienced the same issues as listed in the lawsuit earlier this year, only my 2.4L was not included as an affected model. This car only has 88,000 miles on it and has had at least 9-12 oil changes. My car was working normally until it shut down, no warning, no lights, and no other issues this entire time I’ve had it. I was broken down on a country road in the middle of the night with no phone service. Hyundai claims my car was not one of the engines affected by the recall or lawsuit, yet my car did exactly what others stated happened to theirs.

In May of 2023, my house burnt down. We were in it at the time when the smoke detector went off. When I opened the door from to kitchen to the garage, I saw flames shooting up at the front of my car. The fire was so intense at that moment, I knew all we could do was flee the house. I grabbed my wife and we ran out the front door. You do not have a recall listed for my vehicle, but Hyundai lists two. The first one listed can potentially cause a fire. Both recall maintenance was performed on my car. I sincerely believe that the car was the cause of the fire. Since it had been sitting in my garage for approximately four hours, the engine wasn't hot. I had it regularly serviced at the local Hyundai dealership. There were multiple fire investigators, including one from Hyundai. Here is the recall information.

Unknown cause for internal malfunction of the catalytic converter. Hyundai did have prior issues in 2019 with the publication of a technical service bulletin

The "check engine" light has come on at least three (3) times. The first time, the car went into slow down mode. We stopped at a mechanic, who reset the computer so that we could drive it. We then had it towed to our mechanic, who told us about the problems these Hyundai engines are having. He told us that engine replacement was inevitable. It happened two (2) more times. This time, we had it towed to a Hyundai dealer. The first time, they kept the car for two weeks, only to tell us that they could not "replicate the problem". We opened a file with Hyundai USA [Hyundai Case Management #: [XXX]. It happened again. Same message: "Could not replicate the problem." The blogs are full of horror stories about the engines failing during high speed travel. [XXX] The Virginia Lemon Law does not apply until at least three (3) attempts have been made to repair it at a Hyundai authorized service provider. Our only options appear to be suing Hyundai, or continuing to drive it, running the risk of an engine failure/shutdown at high speed, or trying to sell it to CarMax with a known safety issue. The attached documents show when the incidents occurred. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Paint peeling and chips easily.

Problem with Engine , not holding OIL. Also, I have had 2 catalytic converters replaced within one year. Dealer is telling me my warranty expires at 80,000 instead of 100,000. Last, tail light electrical issue.

I turned on a road that the speed limit is posted 55mph and I accelerated up to about 50 and suddenly my speed dropped back to about 10mph and the car began shaking and the engine light was flashing. There was absolutely no warning at all. I had left my house about 15 minutes prior and everything was fine while I was driving up until then. My engine failed. If I had entered an busy highway I would have most likely caused a Major Accident and been killed and/or killed others. It happened around 5:00 A.M. in the dark which was bad enough as I was alone on my way to work. I had it towed to the Dealership and they replaced the knock sensor and assured me that the car was perfectly safe now. But on Dec. 1,2022 I was driving on a 35 mph road and the car did exactly the same thing and I had to be towed again.This time after much arguing the engine was condemned and replaced.

Jan '22 - Reported check engine light had begun to turn off and back on when gas tank was low. Feb '22 At 19k miles catalytic convertor reported failed for code (P0420), 3 way catalyst, upper and lower gaskets, and manifold all needed to be replaced - took 4 days Aug'23 called to request service for check engine light because it was coming off and on over periods of time. Scheduled for Sep'23 Sep '23 service reports new cat quoted for code P0420, I was not verbally informed by service advisor. 16 Nov '23 driving home and car starts to shake and is slow to accelerate, check engine light started to flash, car enters limp mode, could not drive safely on highway and waited hours for a tow. Codes P0420(cat convertor), P1326 (Knock sensor) 25 Nov '23 picked up car, had catalytic convertor, manifold gasket, knock sensor replaced. Drove 27 miles and car check engine light begins flashing again (P1326) on freeway while merging. Car hesitates, starts to slow, had to merge over to shoulder from far left lane as car had no acceleration. I felt unsafe to exit vehicle being 9 months pregnant. Waited 2 hours for tow back to service dept the same day I picked up vehicle. 8 Feb '24- picked up car from service department. They performed engine combustion chamber cleaning and reported excessive cylinder wall scoring. Service advisor feels confident this fixed the problem. I feel unsafe driving a car that has left me stranded multiple times on busy highways and freeways, especially with children

The oil is burning up so fast. Every oil change that is within the mileage limits they tell me my car is bone dry. If the oil in my car runs out my car engine can blow up or it can stop working. The only way it has been reproduced is that every oil change for 2 years now they have told me it’s bone dry. It has not been inspected by manufacturer. They told me it would cost about $400 for them to even just check it out. There are no warning lights at all.

I was involved in a motor vehicle accident on January 14, 2024. My vehicle was struck head on, left driver side. The airbag did not deploy. I sprain my shoulder, fractured my chest rib, and have a knee contusion. My insurance company deemed my vehicle a total loss. I contacted Hyundai and they advised that because I did not currently have vehicle in my possession, they could not inspect it. I gave Hyundai the contact information to view the vehicle and they refused, stating they do not get involved with insurance company. My vehicle has not been inspected and my insurance claims representative is awaiting a call from Hyundai, to view vehicle at storage location. There were no warning lamps or other symptoms stating that the vehicle had an issue prior to the accident. My vehicle had a successful all points system check in May 2023, at a Hyundai dealership.

While driving down the interstate to go back to my college, I noticed a cloud of white smoke coming out of my exhaust. Seconds later, I no longer could accelerate and white smoke was also coming out of the engine. There were no lights on my dash at this point or at any point before this day. I quickly tried to get off of the road when I noticed my car was no longer going. I managed to get to the side of the road where finally my engine and oil light came on. I waited 2.5 hours for a tow truck on the side of the interstate, where I was barely off of the road. It was taken to the dealership where I bought it (since the car only has 32k miles on it) for a "hole in the engine" which is what I was originally told by the service department. Two days later, I received a phone call that there actually was no hole in my motor, and that the drain oil plug disappeared from my engine while driving, causing all of the oil to spill out of my engine that day on the interstate. Despite getting an oil change only 1500 miles ago from this exact dealer, they stated that the plug would have fallen out immediately after their service if it was placed back incorrectly. Hyundai stated this is now an "owner's problem" and that I was to call my insurance company to get an estimate from them because the dealership would not cover it since it was no longer a warranty issue. I called my insurance company who then got pictures from the dealer of the engine and a video. They then called me stating this ty

NHTSA should have a non-official recall warning for Hyundai vehicles that have this software based Safety Defect, which is some models don't have a Passive Engine Immobilizer, and the vehicles can be easily stolen by starting the engine with a USB cord. Thankfully Hyundai(recall) offered a free Anti Theft Software Update, and a steering wheel lock. I checked my VIN number with the Hyundai Dealership in Oregon, and they said my car already received the Anti Theft Software Update. The only reason I knew my 2020 Tucson had this issue, is because State Farm cancelled my insurance a month after I started paying for it. State Farm and Progressive currently deny new policies for vehicles without a Passive Engine Immobilizer. Also State Farm still denied my insurance after I got the software update. Affected Hyundai models from 2011 to 2021 that have standard “turn-key-to-start” ignition systems/without a Passive Engine Immobilizer, are the Accent, Elantra, Santa Fe, Sonata, Tucson, Genesis Coupe, Palisade, Kona, Venue.

Since earlier in year, continue to get airbag warning light. Stays on for few minutes then goes out. So today checking NHTSA website to confirm if a recall has been issued. As of this date 9/17/23… no information available. So not sure if there is a problem or why the light continues to come on and then off?

Warning lights for Lane keeping, Blind Spot, ABS, Autohold, Foward collision systems came on and will not reset. Reports of this all over hyundai forums and owner fan pages (Facebook, etc). It can fool the driver into believing the car is about to be in an accident prompting panic response in drivers.
