2023 Rivian R1S

I am submitting this complaint after learning through a recent TechCrunch article regarding the NHTSA investigation PE26004 into Rivian rear suspension / rear toe link failures that my incident appears substantially similar to the failures currently under investigation. On March 2, 2024, at approximately 1:29 AM, my son [XXX] was driving my 2023 Rivian R1S (VIN [XXX] ) in [XXX] . While making a normal right turn from [XXX] onto [XXX] and accelerating normally afterward at approximately 30 mph, the vehicle suddenly suffered what appeared to be a catastrophic rear suspension failure. According to the driver, the left rear portion of the vehicle suddenly jolted downward, a loud mechanical breaking sound was heard, and the vehicle immediately became uncontrollable. The rear suspension appeared to collapse instantly. The vehicle then began sliding uncontrollably across the roadway and crossed into the opposite traffic lane. The driver attempted to release the accelerator and correct steering input, but the vehicle did not respond normally. Steering control was effectively lost and the vehicle could not be controlled. The vehicle ultimately impacted a tree on the left rear/driver-side rear area before coming to rest perpendicular to the roadway. Importantly, the loss of control occurred BEFORE impact with the tree. The impact was a consequence of the apparent suspension failure and resulting loss of vehicle control, not the initiating cause of the event. There was no rain and road conditions were normal and dry. Driver-side airbags deployed and Rivian’s emergency response system automatically contacted the occupants after the crash. Police responded to the scene within minutes and a traffic crash report was generated. The vehicle had approximately 7,862 miles at the time of the incident and remained under factory warranty. The vehicle had never undergone any prior suspension repair, suspension service, or suspension INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6

The contact owns a 2023 Rivian R1S. The contact stated that while driving at various speeds, the message "Electrical System Fault - Contact Rivian Service Immediately - Avoid Fording" was displayed along with a picture of the vehicle in water. The vehicle was taken to the dealer, where it was diagnosed that there was an internal short circuit in the HVAC system due to water intrusion or condensation from the HVAC system. The dealer determined that the HVAC system needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 69,000.

Toe link failed on the driver rear side. My vehicle went out of control, veered over adjacent lanes, over the bike path, onto the side walk and back onto the road and side walk. I was left with a sore neck for several days, my apple watch kept trying to call 911 thinking I was in an accident. Anyone one the sidewalk or bike lane or adjacent vehicle lane would have been impacted. The problem has an outstanding recall with Rivian but my vehicle isn't part of the recall. Rivian is repairing the broken components. No warning lamps, messages, or other symptoms before the failure. I was traveling at ~50MPH through and intersection when as soon as I exited the intersection the vehicle turned to the right / banked to the right in an aggressive manner which I could not control. I went across and adjacent lane that was unoccupied sideways and onto the sidewalk then back onto the road.

The driver seat has preset settings for seat adjustments but they do not have Obstruction Detection. We have a rear facing car seat that was placed behind the drivers seat that had to be replaced (by us) as the seat auto adjusted and did not detect the back of the car seat and snapped the car seat out of its base. We contact Rivian over phone and they did not have a remedy (over a year ago, cannot recall exact date). It happened several times where we had to force stop the adjustment to prevent damage to new car seat. Eventually we decided to place the new rear facing car seat behind the passenger car seat instead. The back of the drivers seat has permanent damage from it pushing against the car seat. I did not think about filing a complaint here until I read about the recent Hyundai incident.

Yesterday was the 3rd time in 2 months that the vehicle displayed a "Airbag System needs service - Drive with caution until serviced" warning. I have taken it to Rivian 2 times where each time they replaced various components of the airbag system and it was reported to be fixed. Yesterday the warning returned. I am extremely concerned that Rivian does not have the ability to properly diagnose and or fix whatever the underlying issue is regarding my airbag system. I am now scheduled to take my vehicle in for the 3rd time for them to "try to figure it out".

On five separate occasions the airbag system on my car has become inoperable. Starting in July 2025 I noticed an airbag error on the display of the vehicle. I brought the car in for service and they replaced the steering wheel. The airbag error occurred again in August, this time requiring replacement of a different wiring harness. The error occurred again and again went in for service in November, this time replacing the front seats, seatbelt control modules, and the airbag module. This past weekend the air bag alert appeared again. Rivian seems unable to fix the issue with the airbags on my vehicle creating a significant safety concern.

I pulled into my semicircle, long driveway as I do every morning, and stopped at the top by releasing my foot off the accelerator (no need for brakes as it is an EV). I opened the garage door and slowly stepped on the accelerator, but it started to go fast, and I felt out of control. I immediately released my foot off the accelerator (which should have stopped the vehicle) and slammed on the brakes (there is proof in my driveway with tire marks leading up to the accident) but still did not stop. I quickly realized I was going to crash into the garage, and possibly into the house, so I steered away as much as I could to only drive into and through the side of the garage wall. The space I had would have given me enough time to stop had the car not been driving at a fast speed. Even the neighbors heard braking and ran outside to see what was happening. There is a recording on a ring cam, and you can hear him say "I heard brakes". Oddly, the massive impact did not deploy the airbags. Also, the car usually records all incidents with time before and after (it has successfully done this before when I was rear ended and will if you get too close to anything), but for some reason it recorded what was labeled "incident" and you can only see me pulling into the driveway, the garage door going up, and then the video stops - no record of the crash. The car should have also detected the house. The car only stopped after driving through concrete and stucco, and up the stairs. House has massive damage, personal items in the garage destroyed, and the vehicle is possibly unsalvageable. It took until the next day to see if we could remove the vehicle from my house, but it is now at the service center and Rivian has been notified. I've since researched online and found countless similar incidents.

Front driver wheel had a hub bolt back out rendering the vehicle unable to drive. The car made a loud grinding noise and was unsteady. I had to pull over and was unable to drive any further. It required replacement of the hub bolt and axel. This is a known problem for rivian's and has not been addressed or checked. I reported a grinding sound when I turn 2 months ago and was told that the soonest Rivian could service my car was 2 months away. This known problem and complaint should have flaggged an immediate intervention and this needs a recall.

Front passenger airbag is inactive for long periods of time while a passenger is seated in the vehicle during operation. This is indicated by the message displaying the airbag as being off. This occurs regularly with an adult seated normally in the seat while traveling at highway speeds, for long periods of time. I reported this to Rivian and they said the car is functioning normally but it does not seem safe that the airbag is turned off with a passenger present in the vehicle during operation. I am listing the latest incident date here but this has been persistent since I purchased the car new in 2023.
