2019 Hyundai Tucson

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle hesitated to accelerate while the engine revved loudly. The vehicle then jerked forward while driving. Additionally, there was an abnormal rubber odor detected. The vehicle was taken to the dealer; however, the dealer was unable to duplicate the failure. The failure recurred, and the vehicle was taken back to the dealer, where it remained unrepaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was 10,724.

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 owns a 2019 Hyundai Tucson. The contact stated that the vehicle was consuming oil. The contact stated while her daughter was driving approximately 40 MPH, the RPM increased from 2,000 to 3,000 RPM. There was no warning light illuminated. The vehicle was taken to the local dealer where they were unable to duplicate the failure. The vehicle was not diagnosed or repaired. The vehicle was taken back to the local dealer and diagnosed that an oil change was needed, and the PCV valve needed to be replaced. The vehicle was repaired however, the failure recurred. Additionally, while her daughter was driving the vehicle hesitated and failed to accelerate. The vehicle was taken back to the local dealer and it was determined that an oil consumption test needed to be performed. The manufacturer was notified however, no further assistance was provided. The failure mileage was approximately 41,580.

SEPTEMBER 2019, FOUR MONTHS AFTER WE PURCHASED IT BRAND NEW. THE VEHICLES STOPPED RESPONDING TO MY ACCELERATION ON HIGHWAY SPEEDS WHEN ALL THE TECHNOLOGY SCREENS WENT OUT IN THE VEHICLE. WHILE AT A RED LIGHT THE VEHICLES RPM'S WILL VISUALLY GO UP AND DOWN AND THE VEHICLE SHUTTERS AS IF IT IS GOING TO TURN OFF. IT HAS UNINTENDED ACCELERATION WHEN I'M SITTING AT A STANDSTILL AND GO TO ACCELERATE THE VEHICLE WILL JUMP SO TO SPEAK ONCE THE ACCELERATOR IS ENGAGED. UNFORTUNATELY MY VIDEOS ARE TOO LONG TO UPLOAD BUT I DO HAVE CONFIRMATION OF 2 OF THE 3 CONCERNS BUT AM UNABLE TO RECORD THE HIGHWAY CONCERNS DUE TO OBVIOUS SAFETY REASONS.
