What 370 owners told NHTSA about the 2019 Hyundai Tucson Fuel Cell

My 2019 Hyundai Tuscan has been burning oil and the oil has to be topped off every 1,000 miles or so. There are multiple check engine lights illuminated: abs, front collision, traction. These lights have flashed off and on for 3 years but are not light up solid. This sounds like an issue.

I have been having a number of things happen; 1- my car will lurch forward at times when I release the brake and hit the gas pedal. 2- the forward collision warning keeps coming on. 3- My heating and oil cooler hoses leaking as well as metal lines, all started to leak at the same time.

I believe that this car is a lemon. Ever since we bought it we have problems with the engine not performing right. I have got the engine system cleaned multiple times one at the dealership and one at Valvoline Oil Change facility. The engine still didn't run smooth. I would always get the oil changed on time and the vehicle has never been in a accident. Now just yesterday the vehicle while driving on the highway just stalled and wouldn't accelerate past 60mph. Now the check engine light is blinking and all of the lights on the dash are on. Also lately sometimes the forward collision lights will come on and other warning lights and sometimes they wont. Another light that intermittently comes on are the auto hold and epb light and this has been happening since we bought the vehicle. I have taken into Hyundai and they basically were like yea sometimes that happens. I have not gotten the new check engine light checked but I am sure that it is something serious because the car won't accelerate past 60mph. I have read on other discussions that there are many problems with Hyundai engines and believe that I am victim to very poor quality manufacturing in this engine. I also have a 2013 Toyota Camry with 180,000 miles and haven't had one problem with it. This car is a lemon and would like to have some help with this please. I have also made a complaint with Hyundai under their drive train warranty.

Vehicle engine light has been on for months, it would come and go. I’ve taken it to Hyundai but they kept saying nothing comes up and maybe it was the gas cap needing to be changed. My car also burns oil TOO fast and the dealership has expressed concern. I’ve also been getting a front collision camera disabled message on the dashboard for the last two days. On 3/23/23, my Tucson not only start making a loud noise but the engine light is blinking and barely drives. I almost didn’t make it home safely or at all

While on the road, the 2019 Hyundai Tucson Value dashboard warning lights lit up and stated to check the Lane Keeping Assist and the Forward Collision Assist. The engine light, anti-skid light and power steering light came on as well as the car began to decelerate while in the middle of traffic. I pulled over and turned the car off. When trying to turn back on, the car would not start again until I began pumping the gas with my foot for a few seconds then it started; however, now the engine light was on although it drove normally after that. This has happened to me a few times now, but is very scary because it gives no warning and when I take it to the dealership they can never find anything wrong with it.

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.

Sometimes the auto hold will turn orange and the button sinks in and freezes there. I cannot release it and it does not operate at all. It has happened twice since I got the one recall fixed, once before the recall. I thought the recall would fox it and the dealership thought so also but it did not solve the issue. Since the dealership has new management I have received no assistance from them. The new management has very poor customer service since the change and are still repairing the damage to my engine they said they caused, but i believe could be something to do with a lawsuit which is why they refuse to speak with me.

DRIVING ON HIGHWAYS OR INTERSTATES WITH THE ADAPTIVE CRUISE CONTROL IS WHEN THIS HAPPENS. THE FIRST TIME I WAS DRIVING ON A SWEEPING LEFT TURN AND COMING UP FAST ON A TRUCK IN THE SLOW LANE I WAS DRIVING IN, SO I PUT ON MY BLINKER AND MADE A QUICK LANE CHANGE INTO THE FAST LANE TO GET IN FRONT OF ANOTHER CAR IN THE FAST LANE BEHIND ME. IMMEDIATELY AS I WAS GETTING CLOSER TO THE TRUCK TO PASS IT - SUDDENLY MY CAR PUT ON ITS BRAKES TO AVOID A COLLISION WITH THE TRUCK SINCE THE SYSTEM WAS SENSING THE TRUCK WAS IN MY PATH ON THE SWEEPING LEFT TURN. FORTUNATELY THE CAR BEHIND ME IN THE FAST LANE WITH ME DID NOT REAR END ME. THIS IS JUST ONE OF MANY TIMES MY CAR MISTAKES OTHER CARS AS A DANGER AND WILL BRAKE. IF I PULL IN BEHIND A CAR THAT JUST PASSED ME - BRAKE! IF A CAR IS TURNING RIGHT AND SLOWS DOWN AT THE INTERSECTION AND IS MAKING THE TURN - EVEN THOUGH I WOULD NEVER HIT IT -BRAKE! THIS IS SUPPOSED TO BE A SAFETY ITEM - BUT SO FAR JUST IS SO OVERCAUTIOUS I AM SURPRISED I HAVE NOT BEEN REAR ENDED SO FAR. I DO NOT USE THE CRUISE CONTROL AS MUCH AS I DID WHEN I FIRST GOT THE CAR. I TURN IT OFF NOW TO AVOID SITUATIONS THAT CAUSE THE INADVERTENT BRAKING.
