2019 Hyundai Tucson

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.

The contact stated that it took several attempts to restart the vehicle. The contact drove to her residence while the vehicle struggled but was unable to exceed 25 MPH. 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.
