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 driving to work on Thursday, February 23 2023, the car suddenly turned off flashing the check engine light and oil light. I was driving on the palisades interstate parkway in New York and had enough momentum with the car to get off on the next exit. Once the car was safely off of the road, I opened the hood and pulled the dipstick because the oil light was flashing and it was smoking. The oil light never came on before with the car. The car also had the recall for the knock sensor replacement to avoid this engine failure. I called Hyundai and the salesperson directed me to have the car towed to the dealership at my expense. Once at the dealer ship, the service advisor explained that they have had several cars come in with the same issue and that they would get back to me. A couple days later, they explained that the engine had burned all the oil and that Hyundai would replace it. The issue here is that that was my only car. I have a job and a son while other duties to fulfill. I was explained that it would take a while to get a motor since they’ve had cars sitting with the same issue since December and that they also had a wait of double digits people for the next loaner. I did not get an eta of when I would have my car back or when I can get a loaner. They also will not cover rental fees for a rental car. I have been paying for cabs and other forms of transport and still have no estimation of when I will get my car back.

2019 Hyundai Tuscon experienced engine failure at 66k miles. This vehicle experienced the exact same issues of vehicles Hyundai previously recalled. It is equipped with knock sensor which was supposed to be a "fix" for the known engine issues. A sensor displaying on dash at the same time the engine starts loudly knocking does not make the vehicle safe. The engine still has the potential to fail and catch fire. Hyundai needs to fix all these engine issues. The Hyundai corporate consumer affairs office nor the dealership will return calls or emails about our vehicle.

FEEL LIKE THE EMEGENCY BRAKE IS GETTING STUCK BUT THE DEALER TELLS ME IM WRONG BUT THEY NEVER TEST DROVE IT

NHTSA ODI 11507975

Check engine light has come on twice AFTER the car was at dealers for the recall about the knock sensor. Dealer states the recall fix was implemented, however the light came on a day or two after the vehicle was in the shop. I believe they installed a new knock sensor but I’m not sure, check engine light was off when I picked it up. It’s been approximately 5 weeks since I’ve gotten it back and the check engine light came on again. Friend had a scanner tool and used it - code indicated it was the knock sensor again. Went to dealer and was told there was nothing they could do because the code was cleared. This is a huge safety issue as I drive CA freeways with cars doing 75 mph- it will run for a limited time but it won’t let you accelerate and will get you to the dealer but you must get it to dealer in a very short window- it’s an engine problem and could put me in extreme danger ️

I needed to stop quickly, but not unreasonably fast. I had time to consider my passenger and that this would be a quick stop for them. I then firmly applied the brakes and it felt like something kicked in causing the car specifically not to stop or slow down as expected. I subsequently had to push harder and harder to try to get the car to stop, which it didn't in time and I t-boned another vehicle (minor) that then left the scene. My passenger, who I do not have a relationship with and had just met that night, turned to me and said "you're car didn't stop." She noticed this as well. Upon having it fixed at the auto body shop, they found that "the brake pedal is below the gas pedal and keeping brakes applied when brake pedal is released. The brake pedal assembly is bend and holding brake pads applied when driving." I spoke to the technician (owner?) who said that "if the pedal assembly is bending instead of stopping then it is possible that this caused it." He also suggested that "brake assemblies don't bend" and that he has never seen or heard of one bending in his decades of work. All I know is that I applied the brakes quickly, but not unreasonably and the car reacted in a way causing it not to stop when it should have. Whether this was a problem with the ABS or the brake pedal assembly bending, I am not sure. I do want to document that this car did not stop as it should have and feel that a mechanical problem caused this collision. Fortunately we made light contact with the other vehicle, the air bags did not go off and there were no injuries. There was, however serious risk of injury should cars have been only a few feet further in any direction. This car was repaired by a body shop.

I was merging onto a highway at high speeds when the car stuttered. The check engine light began to flash and I lost acceleration. I could push the gas pedal to the floor and the car would not accelerate at all. The car lost it's speed and I could not go anymore than 30mph, and it would not go higher than 2rpms. It put me and my baby (who was in the backseat) in danger as we were going fast on a highway and out of nowhere the car lost speed and I could not accelerate. I could've easily been hit by another driver going the regular speed limit. I drove it to the dealership that just happened to be down the street, and the car struggled to accelerate from a complete stop, as well as in general. From a complete stop, the car would sputter and jerk when pressing on the gas pedal. The dealership diagnosed it as a faulty Knock Sensor. They said they would replace the sensor as it was still under warrenty. When I left the dealership, the check engine light was off and the car was driving fine. Fast forward to the next day, I was driving again on a highway at about 65mph, when the SAME thing happens. The car stuttered, lost all acceleration, and the check engine light was flashing. I ended up driving it home (about 10 miles away) and the whole time I could not go faster than 30mph without the car shaking. This time the car would not go higher than 1.5rpms. I checked the engine at home and a P1326 code came up, which is a code for the Knock Sensor. I called the Hyundai dealership that I originally went to and they said there was nothing they can do about it at the moment since they had just replaced it. Prior to all of this, there was no warning sign at all that this was a potential hazard. It happened so suddenly and both times it happened put me in a dangerous situation.

While driving, I came to a stop sign and the car completely shut off. The car restarted and then I stopped at a stop sign and the car completely shut off. I had the car towed and they told me that it had catastrophic engine failure. I haven’t even owned this car for 1 year yet. How could the engine fail. Upon further investigation, it appears that this is a known issue with Hyundai Tucson’s of the same year.

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.

This car was stolen because the manufacturer neglected to install an immobilizer in the engine. The car was locked and parked in a secure location, and someone broke the window, opened the steering column and was able to start the car with simply a USB. This incident could have entirely been avoided if it weren’t for the negligence of Hyundai manufacturers for not installing a key component of this vehicle. The engine immobilizer. The car has since been in the shop for 50 days attempting to repair the damage done by the thieves. Charging me tons of money in deductibles, transportation fees, rental coverage. Again, all of this could have been avoided if Hyundai was a responsible dealer.
