2018 Hyundai Tucson

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.

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.

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.

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.

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

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.

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.

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.

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.
