| Oct 2023 | POWER TRAIN,ENGINE | The engine has failed in my 2018 Hyundai Tuscon. I was driving the car daily since purchasing in July of 2023. Everything was fine until the first week of October, I had just picked up my son and was getting on the interstate when my check engine light came on and my oil light would flash on and off occasionally not persistently. I had the car checked immediately and there was no oil in the car at all. I added oil to the car, but it was too late the engine had already blown. I drove my son to school the next morning and the car sounded like a lawn mower and was knocking continuously. The dealership has the car now and this is a known problem with this model car. The car could've locked up while I was on the interstate with my child and we or others could have been severely hurt in an accident or car fire if the engine caught fire. The dealership is not offering to remedy the situation even knowing this is a known problem for their cars. There is already a recall for most of these cars but for my engine the cut off stops at year 2017, I think this should be reconsidered and 2018 should also be included in the recall as I have read many testimonials regarding people having the same problem I had, there was no indication anything was wrong with the oil or engine until it was too late. | Crash: No Fire: No | Unknown |
| Oct 2023 | POWER TRAIN,ENGINE | As I was pulling out of a bank driveway onto a busy access road my car just died. Lost all power. NO warning bells, no lights on the dash, no warning at all. This could have potentially caused an accident. I could have been hit by another vehicle as my car was dead. Pushed it out of the way of traffic, checked oil and there was none. Ended up having it towed to the dealership. The dealership told me that my engine had failed and would need to be replaced due to cylinder 3 rod bearing failure due to oil consumption (a known problem from this manufacturer). | Crash: No Fire: No | Unknown |
| Oct 2023 | ENGINE | The car was making an engine noise and stopped working. My car oil was on level and the oil wasn’t need any change , then was confirmed that the car engine is blown | Crash: No Fire: No | Unknown |
| Oct 2023 | POWER TRAIN | CVT Transmission failed under 70,000 miles. The vehicle is available for inspection upon request. My safety was put at risk due to no warning light or indication of this failure from Dick Smith Hyundai in Greenville, SC during a routine maintenance check. The problem has been confirmed by Dick Smith Service Center. The vehicle has been inspected by Dick Smith Hyundai. There were no warning lamps prior to failure. The characteristics of the CVT appeared in 2018 however; the jerking accelerated over time. Dick Smith Service Center stated not to worry the transmission was okay. October 16, 2023 with less than 70k miles I’m being told I need transmission, starter, & fly wheel. | Crash: No Fire: No | Unknown |
| Sep 2023 | POWER TRAIN,ENGINE | When I accelerate from a stop sign or yield it Jerks and hesitates to accelerate. I have to release the gas and push again sometimes doing this multiple times when this happens daily. I've taken it to Hyundi shops and they say it's a normal chararistic if a Tuscan. It also uses an excessive amount of oil. I am told this is because of the engine. If I go change my oil right at every 3k miles my oil level is well below the minimum line so I have been changing it every 1500 miles. | Crash: No Fire: No | Unknown |
| Sep 2023 | ENGINE,FORWARD COLLISION AVOIDANCE | While driving on the highway going up a 6% grade incline, the car stopped accelerating and car engine stalled out. There were no previous warning signs or indications of engine problems prior to this incident. There was no light that alarmed any defect to the car. The car had always driven smoothly. I maintained proper maintenance and regular oil changes.The car only had 65,000 miles on it. The safety of my passengers were at risk due to stalling out on the highway, luckily there was no harm to myself or others on the road. The dealership confirmed that the engine will need to be replaced. The engine has not been inspected by the manufacture. Unfortunately, due to a rebuilt title was declined warranty coverage. The title was rebuilt due to hail damage, no crash or flood damage. | Crash: No Fire: No | Unknown |
| 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 | 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 | 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 | 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 | 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 | 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 | 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 |
