2023 Rivian R1S

I am experiencing an ongoing and unresolved steering column defect in my 2023 Rivian R1S, which creates a serious safety risk while driving. Issue Details: The steering wheel drops unexpectedly when weight is applied, even lightly. This occurs both while the vehicle is stationary and while driving, including when hitting small bumps in the road. The issue compromises steering stability and could lead to a loss of vehicle control. Repair Attempts & Rivian’s Response: I have taken the vehicle to Rivian Service Centers four times for this issue. Rivian has replaced the steering column three times (May 2024, July 2024, January 2025), but the issue persists. Rivian has now claimed this is a "normal characteristic" of the vehicle, despite previously acknowledging it as a defect and attempting multiple fixes. I requested a written statement regarding their refusal to fix the issue further, but they have not responded. Safety Concern: My father currently drives the vehicle, and I am deeply concerned that the steering column could fail while he is driving, leading to an accident. The steering instability may cause loss of control, particularly at higher speeds or in emergency maneuvers. Rivian’s failure to fix this issue despite multiple repair attempts indicates a potential systemic defect that could affect other Rivian R1S vehicles. Requested Action: I am filing this complaint to document this safety hazard and request that the NHTSA investigate whether this defect affects other Rivian vehicles. Given that Rivian has failed to properly address this issue, I urge the NHTSA to take action to ensure driver safety, including a potential recall if necessary.

the sensitivity of the airbag sensor on the passenger seat is not functioning properly in my opinion. there are times when there is a passenger present and seated, the car is showing that the passenger airbag is off. I took the car to Rivian service center. They indicated that they could not replicate the problem and that to make sure the passengers are over 110 lbs. They also noted that with future software update, they may make it better, which indicates to me that they know there is a problem. I know for a fact that my passengers have been over 110 lbs.

On our drive back from Yosemite, we began descending from Groveland, CA after leaving the Rivian charging station. Due to heavy rain, the car ahead of me was moving cautiously, limiting my speed to about 20 mph while maintaining a safe distance during the descent to Moccasin, CA. Thanks to the regenerative braking, I didn’t need to apply the brakes, as the car automatically slowed when I wasn’t pressing the throttle. However, my windows started to fog up, so I turned on the defoggers. Shortly after, I noticed the car’s door locks repeatedly unlocking and locking by themselves. As we neared the bottom of the descent, I began to smell something burning from the vents. This prompted me to step on the brake pedal for the first time, but it felt unusually stiff, with little travel. The car didn’t slow down, and the burning smell intensified. I pressed the brake pedal repeatedly, but it felt stuck, and the car did not decelerate. Eventually, I was able to roll to a stop. I pulled over to a side street where the issue persisted. I turned off the defogger and contacted Rivian via SOS. We were able to replicate the brake issue on the side street: as I maneuvered the car, the brake pedal sank on its own when the defogger was on. Once I turned it off, the pedal returned to normal. There were no warning lights or alerts from the car system. When I got out of the car, the burning smell was strong near the front wheels. It was clear that my family’s safety was at risk, including 3 young children. The car was towed to a service center, where it’s being inspected. Rivian hasn’t been able to reproduce the issue yet. I believe the regenerative brakes weren’t working properly, causing the car to rely on the regular brakes for the entire descent. This likely led to brake failure at the bottom, with the burning smell originating from overheated brakes. I also suspect that the overheating caused other electrical issues, which could explain why the door locks kept cycling on and off.

1> What component or system failed or malfunctioned, and is it available for inspection upon request? * The sensors don't detect the object sometimes. There were 2 incidents when the car sensors did not detect the object a> In my office parking lot the rear sensors did not detect the fire hydrant and did not make the beep noise resulting in a collision. b> I was driving in my neighborhood; I was blinded by the sun and couldn't see the road ahead. Again, the sensors did not detect the car in front i ended up in a collision. 2> How was your safety or the safety of others put at risk? * I had a collision with another car parked by the curbside. Luckily no one was in the other car but both cars had severe damages. I had bruises on my left-hand forearm. 3> Has the problem been reproduced or confirmed by a dealer or independent service center? * When the first incident happened, I was not able to provide Rivian accurate date and time of the incident and the gear guard did not record the collision although it was supposed to record. So I went back to my office parking lot and i reproduced the problem 1 time after trying several attempts and shared the video with Rivian. I have had too many email exchanges with Rivian to help address the issue but they did not help. 4> Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? * When i reported the first-time issue first time, Rivian inspected the sensors on May 29th 2024 and they said there was no problem with the sensors. But it failed to detect the car in my street and hence i had this collision. I could not see anything as i got blinded by the Sun in the evening. I have a recording from the car's gear guard. 5>Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? * There were no warnings or messages during the incident. However, When it detects it applies the brake. But not this time.

I purchased my vehicle new from Rivian Automotive in November 2023. My rear tire went flat (to 4 PSI) while driving on the freeway on Dec 11, 2023. There was no warning message on the dash that my tire was even low. The truck kept swerving left and right between the lane markers like the lane assist was malfunctioning. Another driver got my attention to let me know my tire was flat. I had my SUV towed to America's Tire where they confirmed that there were no punctures in the tire and that it was defective. This could have resulted in a serious accident simply because I was not given proper warning about the tire pressure.

Our son no matter how we try and position him his chin is touching his chest and starts to bubble during our car rides in the mesa max. He also seems to overheat in it and comes out sweaty even with the shortest car ride. We contacted the mfg and they told us he was too big for infant inserts and too small in the bucket itself.. and to wrap a dish towel around the crouch buckle to help keep him push back more. We then met with a company rep who added additional padding in the back of the seat to help position him better. None or these “fixes” really seemed to help in my opinion, as he still screams and bubbles when in this seat.
