2025 RIVIAN R1S Forward Collision Avoidance Problems

While driving the entire computer shuts down and reboots, both screens go black for several minutes. Speed display disappears, turn signals stop working, after the screens come back on there are warning lights for emergency braking disabled, cruise control disabled, and the headlights won’t come on for several minutes.

The contact owns a 2025 Rivian R1S. The contact stated that while attempting to reverse out of a driveway with the brake pedal still engaged, the vehicle lurched forward, crashing into the vehicle that was parked in front of her, with the entire front end of the vehicle. The vehicle then lurched to the left and crashed into another parked vehicle across the street, where it came to a stop and totaled that parked vehicle. Property damage was reported to the fence that was in front of the parked vehicle. The speed at the time of the crash was unknown. The vehicle was towed to a local auto body shop. No warning lights were illuminated prior to the crash. A police report was filed. The vehicle was not destroyed. No injuries were reported. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 2,200.

Mileage: 2,200

Infotainment system on multiple occasions has started to have lag. Once the lag is present dragging fingers across the main infotainment screen ie navigating a map will cause the vehicle to disengage adaptive cruise/highway assist while driving at any speed. This can also be noted when as the audio output will go out at the same time. Swiping multiple fingers fast as in rubbing something off the screen will cause the system to lag as well.

While my wife was driving our 2025 Rivian R1S (approx. 13,500 miles), the vehicle was at a complete stop when it began to slowly roll forward on its own, followed by a sudden surge of acceleration, despite no input on the accelerator. This unexpected movement caused the vehicle to collide with a Tesla directly in front and involved another two vehicles. This incident posed a serious safety risk and could have injured pedestrians or other drivers. There were no warning lights or error messages before or during the incident. The cause is UNKNOWN at this time. Rivian has not yet inspected the vehicle, but we are requesting log preservation and a full review. This behavior has not been replicated since, and the vehicle is available for inspection upon request. We believe this may indicate a malfunction in the propulsion system, regenerative braking transition, or creep mode behavior. The incident has been reported to Rivian for investigation.

On [XXX], our 2025 Rivian R1S lurched forward while stopped at a red light, waiting to make a left turn. The driver, [XXX] , had her foot off the accelerator when the vehicle suddenly surged forward. She slammed on the brake, and the vehicle briefly bounced back — but then lurched forward again, striking the stopped vehicle in front a second time. There were no warnings or alerts on the dashboard. The incident was captured on video and shows a clear case of unintended forward acceleration. This may be linked to Rivian’s accelerator pedal recall or a software malfunction affecting braking or propulsion systems. I have video footage of this accident but was unable to upload the file. We are concerned about the safety risk this presents to other drivers and are requesting an NHTSA investigation.

I own a R1S and the vehicle is less than 900miles old (21st day of ownership). When driving today on the highway at 75miles - the vehicle suddenly decelerated to 51 miles. I almost got rear ended by a truck and was very difficult to manoeuvre to safe place from the left lane to the right most lane. I parked in a safe spot and saw through several customer Complaint forums that we need to do a hard reset. But the messages were from customers that are 3 years old. I am surprised this still exists as a complaint. I almost died today

On the way home from picking up the vehicle, the adaptive cruise control and the late keep assist functionality failed. The service center determined that one of the front radars needed to be replaced.
