2025 Rivian R1S Vehicle speed control Problems

“I was passing another vehicle on the road when the accelerator pedal got stuck on the all-weather floor mat and made the car virtually uncontrollable. I used the brakes to pull the car off the road and to a complete stop before engaging the parking brake and reaching down to dislodge the pedal.”

“On November 27th the accelerator on my Rivian became stuck causing the car to accelerate quickly and preventing me from immediately stopping the car. There was a message stating that the regenerative braking system was not available and the accelerator pedal was stuck in the down position.

I quickly realized that bringing the Rivian to a full stop would likely cause the car to catch fire. …”

I am surprised this still exists as a complaint. I almost died today”

This unexpected movement caused the vehicle to collide with a Tesla directly in front and involved another two vehicles.
