2025 Rivian R1S

OnXXX, at approximately 5:00 PM CT, my 2025 Rivian R1S was involved in a low-speed rear-end collision at the intersection of [XXX] and the [XXX]. I was merging onto the service road (posted speed approx. 55 mph) behind another vehicle that began its merge through a stop sign, then stopped suddenly. I was moving forward at approximately 5-10 mph while checking oncoming traffic to my left. The vehicle's Automatic Emergency Braking system did not engage, and no forward collision warning was displayed, before I struck the vehicle ahead. I applied the brakes manually only after impact. No injuries occurred. I am reporting this because Rivian has previously disclosed to NHTSA (Recall 25V-585, XXX) a related defect in which its ADAS software misclassified a lead vehicle at low speed. My incident involved the same general failure pattern - the system not correctly responding to a slow-moving vehicle directly ahead at low speed. Additionally, the vehicle's onboard camera/recording system (Gear Guard) had been disabled by the manufacturer service center during a repair visit completed earlier that same day, and was not re-enabled before the vehicle was returned to me. As a result, no independent video record of the incident exists. I have submitted a formal written request to the manufacturer to preserve all EDR, ADAS, and vehicle telemetry data from the date of the incident, and that review is ongoing as of this filing.

Vehicles autonomous driving has failed several times. The system changes from autonomous driving to adaptive cruise control without giving the normal alerts for the driver to take the wheel, giving me or my spouse no time to properly react. This system failing resulted in the vehicle going into a ditch. The autonomous driving automatically switched to adaptive cruise control without warning, the lane keeping system also failed as it gave no warning and did not push the vehicle back into the lane either. Although the vehicle cameras recorded the incident the vehicle did not register any faults or system failures. The shop was not able to find system recorded failures which causes us concerns since the autonomous driving has automatically switched over to adaptive cruise control with no notice.

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.

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
