In this 2019 Hyundai Tucson with about 31,000 miles, engine stalling occurred the second time during driving with two passengers on I-76 at approximately 73 mph in the cruise mode on September 11, 2022; the speed kept dropping and gas pedal did not respond at all; fortunately, the driver could manage to pull over the car to an emergency zone; from the lesson in the first engine stalling incident on I-376 on in October 2021, turning the ignition key to the OFF position then to the "ON" appeared to make the engine work again, like nothing occurred; there was no engine warning light, or OBDII warnings.

2019 Hyundai Tucson I purchased 13 months ago with a mere 5, 241 miles on it., (Currently 29k mi) from Bert Ogden Subaru/Mazda in Edinburg, TX. On 6/26/22 it Started Shaking violently then "rodknocking" and finally failing in middle of major, high-traffic hwy. Near causing accident. NOwarning lights, check engine lights, oil lights, etc. Car was towed to Tipton Ford Hyundai, in Brownsville, TX. As it urns out (through my own research), my vin# falls under a recall issue that was not fixed prior to purchase nor disclosed to me, re:"engine monitoring and logics warning system failure". More importantly, 2) There are several class-action lawsuits underway, one settled, in which Hyundai was found liable for faulty "class II Theta Engines" and a suit involving "GDI NU 2.OL" (same as my vehicle) leading to rod knocking sensor failure, premature worn bearings and even cars catching fire! This is a no-brainer situation in which hyundai should be replacing my engine as ordered, but instead they are claiming, vehicle "neglect" (all maint. receipts were provided)and rejecting claim(which seems to be their m.o. based on similar complaints / civil filings that are ALL OVER THE WEB) and dealer says Im responsible for paying for new engine. Not sure who is responsible: the dealer I purchased from, for selling me a defective vehicle, the Hyundai dealer it was towed to, or Hyundai itself for denying what is a VERY well known liability on their part and apparently a widespread years-long issues with engine defects, recalls, suits, judgements, etx but have many court transcripts of consumers claiming Hyundai blaming thd customer for "neglect" to avoid replacing engine. I need legal help and advice. I HAVE to have car for work and dealer knows it and seems hyundai does, because they wont cover rental, wont provide "loaner" and seems dealer didnt even debate this with HMA because I purchased vehicle elsewhere. They just accepted Hyundai's denial and is now attempting to take advantage.

The contact owned a 2019 Hyundai Tucson. The contact stated while driving approximately 55 MPH the vehicle started smoking and overheating. The contact was able to pull over safely. There were no warning lights on the instrument panel. Once the vehicle stopped the doors were automatically locked. The nearby drivers notified the contact of the fire under the vehicle. Once the contact exited the vehicle, the engine was destroyed by the fire. The inside of the vehicle was still functional. The state police arrived on the scene; however, a police report has not been obtained. The fire department also arrived and extinguished the fire. The vehicle was towed to a wrecking yard. The manufacturer was not notified of the failure. There were no injuries or medical reports. The approximate failure mileage was 40,000.

I helped my daughter buy a used 2019 Hyundai Tuscon with 42K miles since she was going to med school and needed reliable transportation. At 62K miles the engine failed. The engine stalled in the middle of the highway and she was in the middle of the highway for some time before she could restart the engine. She was nearly rear ended. The dealer she brought the car back to said there was no oil in the engine despite the fact that she had the oil changed two months before this incident. There have been many problems with the Hyundai "Theta II" and 2 liter GDI engines that were supposedly fixed and there was a class action lawsuit on Hyundai Tuscons up to 2016 which was well publicized. This car has a 2 liter engine (which is all I know). It does not appear that Hyundai has fixed their engine problems since I believe this is the same problem as before. I am filing this complaint in my daughetrs behalf since she has to take her medical boards in one month. It is bad enough that her car has been tied up for 3 months and she has to transport her husband across town twice a day.

- Lawrenceville, GA, USA

On 2-23-2022, I was driving approximately 30 MPH when all of a sudden there was a noise that kept getting louder which sounded like a knocking or broken fan, the vehicle RPM increased, the vehicle hesitated, did not accelerate, stalled, the check oil and engine light came on, I coasted into parking lot. When I opened the hood, there was no signs of smoke, oil leak, or smells, however, when I went to check the oil, smoke came out of where the oil dip stick goes. I attempted to have the vehicle jump started with no luck, just a clicking sound. I had the vehicle towed to be serviced.

- Woodbury, GA, USA

While driving down a busy road at 10:00 pm on New Years Eve, my vehicle's engine completely shut off. Immediately prior to the shut off, the vehicle's dash displayed the oil and battery lights. The vehicle's automatic emergency brake and steering wheel lock were both engaged, not allowing me (or the tow truck company) to move my vehicle out of this busy road. My car remained in this location for 3 and a half hours. The hazard lights stopped working after the first hour, making it extremely difficult to see that the vehicle was stopped. After the second hour, an officer parked behind my vehicle with their lights flashing as he said it was an extremely dangerous situation and my car was sure to be hit. He was able to get a tow truck to me before Hyundai. For hours, numerous people were forced to brake quickly/swerve into other lane to avoid hitting my car. This occurred right before an intersection, putting 4 directions of drivers at risk of collision. I stood in the rain, near my car, attempting to help direct drivers away from the lane until the police officer showed up. The vehicle is now at the dealership which confirmed engine failure, pending replacement. Possibly related, this vehicle had the catalytic convertor replaced 3 months prior. It is not yet confirmed if this contributed to the engine failure.

The engine in my 2019 Hyundai Tucson turned off while driving down the interstate without any lights or warnings. My 2 year old was in the back seat at the time, and this could have caused a significant risk to not only myself and son, but others on the road if we were not traveling at highway speed. The vehicle was safely pulled over to the side of the road and would not restart. I got it towed to the dealership it was purchased from and they informed me they have been having a lot of issues with engines recently and mine would need to be replaced. It has now been sitting at the dealership since Thanksgiving waiting to be serviced, which is covered under manufacture warranty. It is located at Hyundai of Brunswick in Brunswick, Ga and can be accessed if needed.

- Brunswick, GA, USA

Purchased the vehicle in June 2021 only had 1 previous owner. The dealership stated it was a pre-owned certified used vehicle that had just been inspected and service. Within the first month I had to take it back for multiple issues most recently the catalytic converter to be replaced and the Engine. I haven't even owned it let alone driven it long or far enough for either of these parts to need service or have failed. It's not even time for my first oil change that how low the mileage is that I've put on it. The dealership originally told me they never head about the complaints regarding the engine now they are trying to stiff me on selling me a lemon by charging me 3000 and telling me Hyundai isn't willing to cover the repairs. If this is a known issue which is seems to be a recall should now be issued.

- Alsip, IL, USA

The contact owns a 2019 Hyundai Tucson. The contact stated that while her husband was driving at an undisclosed speed, several unknown warning lights illuminated. The vehicle was taken to an independent mechanic and diagnosed with engine failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 86,000.

- Parkville, MD, USA

Purchased the car in March 2021 with 41,391 miles on it. The day after I picked it up check engine light came on checked the code it was a P0420 catalyst system efficiency below threshold, contacted dealer they took the car in and replaced the catalytic converter. Now 8 months later & a little less than 15,000 miles the check engine light came on again and guess what code popped up? P0420 now I am not an auto expert but I don't think its right that a catalytic converter would need to be replaced twice in that short time frame. Time to figure out what is causing this considering I am not the only one who has reported this
