2023 Rivian R1S

The vehicle experiences recurring, uncommanded high-speed steering "lurches" where the Lane Keep Assist (LKA) system initiates aggressive, sudden steering inputs at highway speeds (65+ mph). These inputs force the vehicle out of its lane and require immediate, significant manual driver counter-steering to prevent collisions. These events occur without warning, despite no perceived environmental triggers. This issue involves the vehicle's automated steering and Lane Keep Assist software suite. This safety defect renders the vehicle inherently dangerous to operate at highway speeds for the driver, occupants and everyone on the freeway. This issue is not isolated to this vehicle; numerous owners have reported identical, terrifying high-speed steering shoves on public forums for over a year. There is credible evidence indicating that the manufacturer's executive leadership, including the CEO, has been aware of these fleet-wide issues for well over a year. Despite this knowledge, the manufacturer continues to characterize these life-safety events as "Operating as Designed" or "No Fault Found" (NFF). This issue has been reported to the manufacturer’s service center repeatedly over several months by myself and other owners. Despite the manufacturer claiming to be "diagnosing" or "duplicating" the steering failure, telemetry data from the vehicle (including odometer audits) confirms that the vehicle remains stationary at the service facility for extended periods with zero diagnostic miles driven during these "repair" attempts. Other service appointments show minimal miles driven. The manufacturer has replaced safety-critical steering hardware, including the steering column assembly, without resolving the persistent software-driven steering lurches. The manufacturer’s refusal to acknowledge the defect or conduct meaningful, speed-appropriate road validation, despite being notified of the systemic safety risk, suggests a failure to address an acute life-safety hazard.

The vehicle's infotainment, driver gauge cluster and on display safety systems all fully lock up and reboot after about 30 minutes of driving. If you have highway ADAS engaged, warning sounds will occur but no display explaining the warnings. If you're using the vehicle's safety systems you suddenly do no have blindspot monitoring, or enabled ADAS. Additionally, navigation will not be available causing immediate confusion.

Low Tire Warning either failed or is defective. On Dec 11, 2023 my rear tire went flat (to 4 PSI) while driving on the freeway. I was driving for about 25 miles on the freeway when the Rivian R1S truck kept swerving left and right between the lane markers like the lane assist was malfunctioning. Another driver pulled up on the side of me and got my attention by honking their horn to let me know my tire was flat. At this point the rear passenger tire was dangerously low. There was no warning message on the dash that my tire was dangerously low. This could have resulted in a serious accident simply because I was not given proper warning about the tire pressure. I believe that the tire is defective, so had the truck towed to a tire shop to inspect and replace the tire. The truck is about 30 days old with 1,801 miles on it.

Rivian released a software update that bricked my vehicle. It is drivable but the infotainment screen and safety features are inaccessible. It is unclear what features work and which ones do not. Rivian has only released limited information on Reddit, and there has been no other formal communication to impacted owners. Customer service said it was aware and that the team was working on a resolution, but this is a major red flag and should be investigated.

Immediately after purchasing the vehicle, I got error codes thrown to service the suspension while driving to my house, specifically at 15-20mph over traffic calming bumps. This fault cleared immediately the first few times. On July 25 I submitted a service request as my family headed out on a two week, 900 mile trip. The service suspension fault had returned and disabled my ability to change modes/ride heights, blind spot sensors and cruise control, all of which I was counting on using during trip. I shut off and restarted the vehicle several times trying to clear the fault and regain functionality, but the fault inevitably returned. On July 25, Rivian added a response in the service portal that they would address the problem by July 28th. I heard nothing more. On August 1, I was driving south on HWY 57 in North Idaho. I hoped that code would have cleared, but it came back on almost immediately. After driving for about 5 miles, I decided to pull over at a visitor center parking lot to try and reset again to change modes, regain safety sensors, and cruise control. While turning left into the parking lot, another driver tried to pass on my left on a double yellow line driving above the 55mph speed limit. He collided with the front left part of my vehicle, damaging the body and breaking the front tie rod ends, leaving me unable to steer or drive forward, disabled, in the oncoming traffic lane. I asked Rivian to share data about the turn signal use, brake light, and speed data at the time of the accident with me. They did not respond in writing, but called and refused, getting quite angry during the call. After researching and observing other Rivians, I don't believe that my brake lights were on during regenerative braking. The rear, side, and blind spot sensors were disabled. Turning 1/4 second sooner or 5º sharper would have killed me.
