2020 Hyundai Venue Speed Control & Cruise Problems

Was driving at speed down the highway (70+MPH) for an extended period of time traveling around 1.5 hours and then acceleration started having issues. I wouldn’t change the pressure on the gas but the RPM gage would go up and down wildly although I hadn’t done anything and cause a jerky forward motion. This cued me that something was wrong. Then there was an accident up ahead which caused traffic to come to a stop. When I braked for the complete stop it was a hard brake although I pressed lightly on the brake. Then when I got up to speed again (70MPH) I tried to accelerate above 70 to keep up with traffic and I couldn’t get the car to go faster. I floored the gas pedal but there was nothing happening. Luckily I was able to make it to the far right lane and coast up an exit ramp to put on my hazards. Once I stopped in the shoulder on an exit ramp I was in park and tested the gas. There was nothing happening. I turned off the car and then restarted and hit the gas and the car accelerated but when I pushed the gas again it wouldn’t accelerate. Once the car was turned on you could only hit the gas once to make the car accelerate otherwise the gas pedal did nothing. This was extremely dangerous traveling on the highway and could get someone killed. I was lucky there was an accident and traffic slowed down. My car has less than 20K miles on it so I’m extremely surprised that such a serious issue occurred. I have now found out other Venue users have reported similar issues in online forums. PLEASE TAKE THIS REPORT SERIOUSLY!

I was driving my car on the way back from a trip, about an hour away. While driving about 70 MPH on the highway, my car started to feel like it was lurching forward, and the RPMs started shooting up and down uncontrollably. I tried to write it off as faulty cruise control or the shoes I was wearing, so I switched both of these things. Finally, the RPM shot up to 7000 without warning or cause. I drove 45 mph the rest of the way home as to ensure my safety. No dash lights or warnings had been given to signal that something was wrong with the car. Upon getting pretty close to home, I stopped at a red light. My car sounded as if it had shut down. The light turned green, and despite pressing the gas, the car did not move. Only at this point did the battery light and oil light come on. After restarting the car, no lights remained, and I was able to continue home. I took it to a private mechanic, who stated that he could not recreate the problem but that he believed it was a transmission issue. He advised I take it to Hyundai, which I did. They also told me they drove the car and could not recreate the issue. I was assured my car was fine. Despite this, every day I drove to work or school, I could feel my car doing the same thing. It seems as if every time I tried to maintain speed, the RPM would shoot up and down uncontrollably and gain speed on its own. Finally, as I was returning from a friend's apartment, every time I hit the brakes, I could feel my car sputtering, as if it was about to give out. When I would try to accelerate, I would have to use a lot of pressure on the acceleration to get the car to even go, and it could not gain speed. Once stopped, it was incredibly hard to get the car to move at all. Luckily, I was only a few minutes from home, as if I was much further, I do not believe I would have made it.
