The gas pedal, would not work as I was trying to accelerate when going from the ramp onto the freeway. The pedal had no pump in it, it just went all the way down as I was trying to press and the car started slowing down. I had to pull over on the side of the freeway and restart the car for the pedal to start working again. I came to the dealership the next day on 12/5/25, at around 5:45pm in which I was scheduled to come back at 8am on 12/6/25. My safety was at risk, because the car lost pedal power for me to pickup speed as I merged onto the freeway. I brought it in for inspection, at the dealership I purchased it from. There were not any signals or displays that came on during the incident.
While it may sound bizarre, I can definitively demonstrate that whenever I am present inside a car, the car become very unstable and bouncy and unsafe to operate. Not only does it not steer straight the car also becomes incapable of coasting smoothly and is constantly racing or aggressively slowing down. I can’t be the only anomaly and whatever is causing this could be widespread and is certainly dangerous. I have found it to occur only with the cars which I am inside. I would like to demonstrate this in person if possible to an investigator.
Towards the end of January, my car computer was reset because the car was telling me that I needed an oil change early and the dealership told me it could just be a computer issue. I then took my car to get an oil change and full vehicle inspection on February 24th, 2 days after that on the 26th I was leaving my school parking lot when the vehicle accelerated awkwardly when I was leaving out of a parking spot, I was then able to gain control back over the speed until the vehicle again abruptly accelerated and jerked to the left sending my car over a curb, deploying the air bag, and completely totaling out the vehicle.
The car was giving me an issue with the forward radar blocked which was coming and going as if the radar was loose. This issue persisted for a week and the error was still coming and going after every 10-15miles of drive. Later after a week the error was constant screen and the radar is still intact to the car. Error on the screen: ######forward safety system disabled. Radar blocked. #####.
