| Sep 2023 | UNKNOWN OR OTHER,ENGINE | Lots of engine oil consumption And transmission since I bought car spend excessive engine oil and transmission fluid as well | Crash: No Fire: No | Unknown |
| Sep 2023 | UNKNOWN OR OTHER | Was told Hyundai is having a problem with motors and it’s burning oil quickly. There are recalls for it but not for my model and year. And my mechanic told me I have the same problem. Hyundai should extend the recall for 2018 Tucsons | Crash: No Fire: No | Unknown |
| Sep 2023 | ENGINE | I am the second owner of this vehicle. Ever since my car had around 60,000 miles on it, at which time I still had extended warranty purchased, I've been having issues with the oil consumption. I started the oil consumption tests, after the first part of the test it was proven that my car was consuming too much oil. During the 2nd part of the oil consumption testing, the dealer ship did an engine combustion cleaning, which supposedly helped with the consumption of the oil. I was back to having the same issue with the engine consuming my oil only 4 months later. So now I am currently doing my second oil consumption testing. At both tests, I was assured that if my engine fail these tests, I will be getting a new engine for my car at no expense to me, and that Hyundai would cover all the costs. I currently failed both parts of the test and got approved for a new engine, but I will be responsible for covering 20% of the cost of the engine (around $1800). It was obvious that my car was having oil consumption issues when I still had my extended warranty (it expired at 72,000) and maybe my extended warranty wouldn't have an issue with covering the cost of the engine just like Hyundai is having issues. I hear and read about so many people having this issue and complaining about Hyundai this is ridiculous. I purchased this vehicle and gave me trust to Hyundai and all I've been having is issues with this vehicle. Also, before starting my second oil consumption testing, my catalytic converter got so clogged up from the engine oil that my vehicle lost power. I drive my car with my child in it, and being on the highway while the car loses power was very dangerous for us. Hyundai should be ashamed for selling people these cars that don't last | Crash: No Fire: No | Unknown |
| Sep 2023 | UNKNOWN OR OTHER,ENGINE | The engine, rod bearing failure, constantly ABS Kits, Engine monitoring system (car is available for inspection). Our safety and others put at risk because the auto stopped dead on Interstate during rush hour traffic barely escaped death and seriously injuries to all travelers close to us. Towed it to a dealer for diagnostic testing who confirmed it's the engine and rod bearing system on report of inspection and estimate invoice. Manufacture told us to take it to a dealership and we took it to Wallace Hyundai of Stuart Florida. The warning was a knocking sound and oil light flickering just before auto began to sliw down to final stop. All took place on August 8, 2023. I have 7 photos to upload but your site is not allowing more than 10 documents. I tried to delete some documents but it did not have a delete function once I uploaded the documents. | Crash: No Fire: No | Unknown |
| Aug 2023 | ENGINE,FUEL/PROPULSION SYSTEM | The car is having problems excellating when you push the gas it take it a moment to realize the gas is push and it needs to go | Crash: No Fire: No | Unknown |
| Aug 2023 | ENGINE | The contact owns a 2018 Hyundai Tucson. The contact stated while driving 35-40 MPH, the check engine warning light illuminated, and the engine made an abnormal rattling sound. Additionally, the vehicle lost motive power. The contact was able to pull to the side of the roadway. The vehicle was towed to the dealer, where it was diagnosed and determined that there was a piston failure in a cylinder which caused the engine to seize. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and offered to cover 60% of the cost for the repair. The failure mileage was approximately 131,000. | Crash: No Fire: No Towed | 131,000 |
| Aug 2023 | POWER TRAIN,SERVICE BRAKES | Transmission is jerking when driving. Brakes are squeaking. | Crash: No Fire: No | Unknown |
| Aug 2023 | ENGINE | My vehicle is burning 2 1/2 quarts of oil a month , my catalytic converter is clogged due to this, Hyundai is fighting me and will not take responsibility for either. With some research I’ve found they they do know about the issue in thousands of their vehicles and they are refusing to help anyone. I was driving up the road and my speed declined to 8mph & would not go any faster | Crash: No Fire: No | Unknown |
| Aug 2023 | POWER TRAIN,ENGINE | This very low mileage vehicle recently had the same incident for I believe the fifth time since I've owned the car. In a very dangerous situation the car exibited the car going almost dead after normal acceleration. It regains power after 3-5 seconds and rapidly returning to acceleration. It happened to my wife soon after purchase and she has refused to drive it since. Last week while I attempted to make a left turn at a yellow light it again went dead and traffic was forced to slow while the car behind me almost rea ended me. Recently the engine seems to run rough at times. Never have I seen any engine trouble lights since I've owned it. Three separate Hyundai dealers have looked at and seemed to be aware of what's causing it, but chose their words carefully. My neighbor owns one of the largest new cars dealerships in the Midwest. I spoke with him about this problem and he said his used car manager would NEVER purchase one with this engine/transmission for resale! A Hyundai service manager told me to get rid of it soon. When told I was planning on gifting it to my daughter, he said he wouldn't... The car only has 33,000 miles and looks new. Always garaged, never driven in snow. | Crash: No Fire: No | Unknown |
| Aug 2023 | ENGINE | In May 2023 while on family vacation my tucson oil light came on and went what I believe in limp mode. Oil has always been changed on time, checking oil, was full and clean. Had to tow back from TN to PA. Called hyundai and they stated that the engine has a known problem and a campaign is on them. I then had it towed to a hyundai dealership for a June 9th 2023 appointment. The dealership didn't even know why they let me make it. They had 9 tucsons with same problem in front of me. Now Aug 6th 2023 still waiting at dealership to be even looked at. Unreal | Crash: No Fire: No | Unknown |
| Aug 2023 | ENGINE | At about 60k miles I noticed the check engine light would come on and so I checked the oil only to see it completely empty. I get regular oil changes and have documentation. I took into Hyundai to get recalls fixed and mentioned the excessive oil consumption to them and the service manager stated that it was not enough oil consumption and I would have to pay to diagnose further. Well I have contacted Hyundai corporate and they denied looking any further at my vehicle. So I have been goin to my oil change place about every 2-3 weeks and I have records that after about 1,000 miles I am having to put two quarts of oil in. Current mileage now is 100k and the value of my car is like $5-8 dollars. I owe 23k on this vehicle! I was also not told it was in a n accident when I purchased it. | Crash: No Fire: No | Unknown |
| Aug 2023 | ENGINE | Vehicle purchased Jan 2023. Vehicle began making suspect noises in June 2023 and was taken to Ford dealership where the car and extended warranty were purchased in January. We were told that the noise was believed to be due to low oil. Oil was changed as part of maintenance covered under the extended warranty. About 5000 miles had been driven since last known oil change that was done prior to our purchase of the car in January. On Jul 19, 2023, vehicle began to make loud noises again and had difficulty accelerating. The same day, engine stopped while exiting highway. Car was found to have little to no oil in it even though it had been serviced 6 weeks prior and had only been driven ~3000 miles. Engine was knocking badly but did not seem to be overheating. Three quarts of oil were added, but the car cut off when put into drive. Vehicle was towed to Ford dealership where it and extended warranty were purchased. Ford dealership declined to work on the car and stated it should go to Hyundai because the engine needed to be replaced. Due to long wait for Hyundai appointment, the vehicle is currently being assessed by a certified mechanic. I am looking to Hyundai or Class action lawsuits to see if this vehicle and situation will be covered by the manufacturer. We do not know the exact cause of the failure yet and if it will be covered. My mechanic is working with Easy Care warranty company. There were no warning lights, no check engine light, no gauges indicating it was overheating or low on oil. | Crash: No Fire: No | Unknown |
| Jul 2023 | POWER TRAIN | Immediately after purchasing the car I stopped for gas. When pulling out of the parking lot and onto the road, the transmission stalled. The car did not move, the rpms jumped to 5-6 and the lurched and jerked forward then stopped and lurched forward again with the rpms jumping high. This had happened numerous times to various deplgrees since purchasing the car 48 hours ago. There were and continue to be no warning lamps or messages on the dash. I have an appointment with the dealer to have it assessed in a week. This is dangerous because it causes the vehicle to not pull into or cross traffic in a smooth, sage and predictable manner, potentially causing a collision. | Crash: No Fire: No | Unknown |
| Jul 2023 | ENGINE AND ENGINE COOLING | The contact owns a 2018 Hyundai Tucson. The contact stated that while driving at 65 MPH, the vehicle lost motive power, prompting him to pull to the side of the roadway, where the vehicle failed to restart. No warning lights were illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the catalytic converter. The vehicle was repaired, but the failure reoccurred. The vehicle was returned to the independent mechanic, who again diagnosed a failure with the catalytic converter. The vehicle was repaired a second time, but the failure reoccurred a third time. The manufacturer was notified of the failure but was unable to provide any assistance. The failure mileage was 85,000. | Crash: No Fire: No Towed | 85,000 |
| Jul 2023 | POWER TRAIN | Back in January of 2023, car would not go into reverse. While out driving the engine light came on and went into safety mode. I had no power to merge onto highway and make it up hills to get to Hyundai service repair. They said the gear actuator failed. They repaired, but within a week the car was not going into reverse and engine light came back on. They had my car for over a month with no loaner car. They replaced transmission. Car only had 32,000 miles on it. Yesterday, July 28, car started losing power in traffic. Sometimes car would lurch. Engine light on so I pulled into grocery store parking lot. Turned car off and when I turned back on a loud clunking noise. Called Hyundai and drove to service. The entire time the car struggled to merge or go up hills. They ran test and said the gear actuator failed. So this is a trend. It is under warranty but that is not the point, this is dangerous and you can get stranded or the car can lurch or loose power at any time. I complained to Hyundai the first time and they did nothing except repair under warranty guidelines. | Crash: No Fire: No | Unknown |
| Jul 2023 | POWER TRAIN,FUEL/PROPULSION SYSTEM | The car has acceleration issues and when you try to press down on the gas it sputters and loses power, it is becoming a safety hazard when driving 45 mph or higher. If you try to pass another vehicle it slows down and almost stops, we have had to pull to the side of the road to avoid being in an accident. This is NOT normal for a vehicle to do this and something needs to be done before we end up dead. | Crash: No Fire: No | Unknown |
| Jul 2023 | ENGINE | On Sunday July 16 while driving home from Cape Cod to my home in Walpole, my engine stopped working while on the highway in Plymouth, ma. I promptly turned on my hazards and had to get over to the travel lane as I was in the passing lane when this occurs.The oil light was flashing as was the engine light and I had to coast to a gas station. Thankfully the exit was a downhill one | Crash: No Fire: No | Unknown |
| Jul 2023 | ENGINE | On April 30th my cars check engine lite came on while driving on I84 with multiple people in the car, the car slowly started to lose momentum and could no longer accelerate. The next available appointment at the local dealership (MotorWorld, Wilkes-Barre PA) was on May 22nd. It was then confirmed that my knock sensor detection was faulty. It was recently recalled or something along those lines. It was then fixed on May 22nd then returned to me. On May 23rd less than 24hrs later my car was being towed back to the dealership as the check engine light had come back on, code P1326, after having fuel injectors 2 and 3 replaced and the engine cleaned, Hyundai tech line declared my engine needed to be replaced. However, Hyundai is refusing to replace the engine even though it is code P1326 (knock sensor detection) that has called my engine to now become faulty. Replacing the knock sensor has not fixed the problem. It is now July 18th and I still do not have my car back as it is sitting at the dealership, undriveable. | Crash: No Fire: No | Unknown |
| Jul 2023 | ENGINE | The contact owns a 2018 Hyundai Tucson. The contact stated while driving 75 MPH, the vehicle shut off with the check engine, oil, and additional unknown warning lights illuminated. The contact called his brother for a jumpstart, but the vehicle failed to restart. The vehicle was towed to a friend's residence where his brother inspected the vehicle and discovered a hole in the engine block. The vehicle was then towed to the contact's residence. The dealer and the manufacturer were notified of the failure. The vehicle was not repaired. The failure mileage was approximately 123,400. | Crash: No Fire: No Towed | 123,400 |
| Jul 2023 | ENGINE | i was driving on the freeway on Nov 22, 2022 when without warning my car went into limp mode. the engine warning light flashed. this puts the driver (and any passengers) at great risk, as the engine is severely limited in its power output. the car will move, but very slowly and acceleration is weak to non-existent. at highway speeds, this situation could have also impacted anyone behind me who came upon my limp vehicle and could not react in time to my slow speed. it has 60,250 miles on it. i drove home, had an initial diagnosis at a local auto repair shop as follows, "removed the (spark) plug and it is badly damaged with oil in cylinder indicating an internal engine problem". i had the car towed on Dec 7, 2022 to the dealer where i purchased the vehicle. the dealer could not look at the vehicle until Feb 17, 2023 when they diagnosed a burnt valve and the engine would have to be replaced. on Feb 21, 2023 i was told that the replacement was awaiting approval and should only take a day or two. it took until May 19, 2023 to approve the engine replacement under warranty. as of this writing (July15, 2023), i am still waiting my turn at the dealership for the engine to be replaced. it appears that i am not alone in this situation of Hyundai/Kia producing bad engines that prematurely fail and then have to fight for a warranty replacement. i have been almost 8 months without my vehicle. | Crash: No Fire: No | Unknown |
| Jul 2023 | POWER TRAIN | Tucson 2.0L hesitation at acceleration particularly from a rolling stop: This intermittent problem was checked initially by Marhofer Hyundai in Cuyahoga Falls Ohio, their findings were negative. We then took it to Great Lakes Hyundai in Streetsboro and they said they were aware of the problem and reset the computer, but it did not resolve the problem. This problem has put my family in harm's way many times, making a turn from a rolling stop the car lags into ongoing traffic. Our last visit to dealership we were told car was out of warranty 19,000 miles but the problem was never fixed. This vehicle was a certified pre-owned and have an extended warranty. I have attached a technical service bulletin. | Crash: No Fire: No | Unknown |
| Jul 2023 | UNKNOWN OR OTHER | Paint on the bonnet started peeling and flaking off. You can easily slide your finger on the edges of the paint and it will peel right off. | Crash: No Fire: No | Unknown |
| Jun 2023 | POWER TRAIN,ENGINE | i received a letter in the mail stating the nock sensor has been replaced i dont know howlong ago but my 2018 tucan is stuck in false sage mode saying the nock senor was bad! if it is a on going issue and there is has been a recall on the part why does it show no recalls for my mode car? | Crash: No Fire: No | Unknown |
| Jun 2023 | ENGINE | These people have sold me a car that is burning oil and they refuse to honor their settlement made by a class action lawsuit against them to replace the motors that are in fact burning oil. At first they told me that they would seal the oil and for me to drive 1000 miles and return to them so that they can determine if the car was leaking or burning oil. Upon return they did in fact say that it was not leaking and that it was burning oil but it was "not burning as much oil as it should in order to replace the engine". In what world should a car burn oil? This car is too dangerous to drive, the other day the engine shut down as I was driving it on I75 which put my life in danger due to its lack of oil. I have reached out to corporate and unfortunately no resolution. Should I wait until I get into an accident or the engine completely burns down as I am driving it for it to satisfy their requirements to replace the engine? | Crash: No Fire: No | Unknown |
| Jun 2023 | POWER TRAIN,UNKNOWN OR OTHER,ENGINE | I have only owned the car for 1 month. I had gotten an oil/filter change and a new oil pressure sensor at ~80,100 miles. I had requested the oil sensor be changed because it would flicker on and off when the car was idling/low RPMs once it had heated up fully. This had fixed that issue seemingly. At ~80,700 miles the car had started riding a bit "rough", especially at higher speeds, so I decided to have a look under the hood. I was terrified to see that my dipstick was bone dry. There was never any evidence of any noticeable leak underneath the car on the driveway nor any evidence of blue smoke coming out of the exhaust. After some research (Hyundai corporate was telling me over the phone multiple times that there was no known issues with my specific car/engine) I was appalled to see I was essentially lied to. I found multiple official TSBs, NHTSA notices, and hundreds if not thousands of other customers noting the exact same experience. I had tried to take it to Hyundai for the oil consumption tests laid out in multiple TSBs but I was denied "due to the original warranty expiring". To my knowledge this exact issue has caused Hyundai and Kia to extend to 150k miles for all owners. This is my only mode of transportation and I am so worried my car will stall/seize/catch fire on the highway. This is beyond unsafe and unacceptable but I assume I may have to wait until the final litigation hearing in September for official recalls to be issued. If my car makes it that long. | Crash: No Fire: No | Unknown |
