2019 Hyundai Tucson

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.

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 bought my Hyundai Tucson 2019 brand new, it has 38000 miles on it still under warranty in the past two months engine light came on three different times brought it back to two different dealership still have same problem, my car still in dealership parking lots waiting for three different parts from Hyundai, my car is not safe to drive and I feel there are cover up about engine problem with the Hyundai Tucson 2019, please I need help to to solve this problem thank you

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.

The contact drove the vehicle to an auto parts store and had a diagnostic test performed. The contact was advised that she had a code P1326 and other failures of the powertrain system.

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.

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.
