2023 RIVIAN R1S Complaints

Passenger seat does not detect light to normal weight/BMI adult buckled in and disables the front passenger airbag. Vehicle service state it is working as intended. Therefore, for all intent and purposes the vehicle does not have passenger airbag.

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.

The single horn on this vehicle is incredibly weak/not loud enough and has almost led to two separate incidents in my 3 months of ownership due to other drivers not being able to hear my horn.

The vehicle horn is not very loud and makes a low frequency noise that is not easily recognizable as a vehicle horn. The horn presents a safety risk to vehicle occupants, other vehicles and pedestrians.

I was headed straight but stopped so that I could move into a left turn lane. As I got into the left turn lane and was straightening up behind the person in front of me at almost a dead stop the R1S lunged forward and accelerated at a high rate of speed hitting the car in front of me (speed control issue already known on the R1T). The camera footage verifies it. No warning lights went off (forward collision avoidance, automatic emergency braking) that there was a car in front of me and to brake (normally if there is a car in front of you that close and the vehicle thinks there will be a collision the screen goes red and the letters BRAKE come up bold in black, the car will brake if it thinks you may hit something). Of course now all my side sensors don’t work. I am still waiting on diagnostics from Rivian. Additionally, my seatbelt didn’t lock throwing me forward. I have only had this SUV two months with 848 miles. The car in front of me had substantial damage. If anyone had been in her backseat especially a child they would have been injured. My safety was in danger with the seatbelt not locking. I am waiting on the diagnostics still from Rivian. Insurance is waiting on Rivian. There had been nothing like this prior to this incident.

I was at 44% state of charge and the ambient temp was around 65 F. While taking a turn at an intersection, the vehicle reduced regenerative braking(regen bar on the vehicle was greyed out) had I had quickly break as the car started to coast. This only lasted for 8-10 secs and the vehicle had regular regen breaking. Rivian don’t have blended braking, so if that had happened in different situations that needed much faster reaction time I would be in trouble. Issue 1: vehicle randomly decided to go into reduced regen for a brief period even at ideal conditions for regen( low SoC and normal temp, vehicle drive only for 5 mins) Issue 2: There is no blended braking to compensate for this in such situation, putting the driver/passengers at risk

The front Passenger seat intermittently disables the Passenger Air Bag System, depending on the movement of the passenger. For example, my girlfriend was sitting in the seat, with her legs crossed. When she is in this position, the system disables. If she shifts her weight around, the system reenables. This is repeatable, with numerous members of my family. I had the vehicle in service, and they were not able to reproduce the issue (No trouble found). As soon as I got my daughter, in the care ,the issue presented itself once again. My daughter is 108 lbs.

OTA update 2023.42 failed to install and left car without working screens, the only way to really manage the vehicle's settings. No formal communication until mid-afternoon next day, approximately 16+ hours after problem became known. Rivian stating vehicle can be driven without speedometer and working systems.

Rivian pushed a software update to owners on the evening of 11/13/2023. This update made the driver information and infotainment screens non-functional and also disabled all driver saftey aids and any ability to turn exterior lights or windshield wipers off or on. As of 11:24 am CST on 11/14/2023, owners have still not been officially notified or provided any status updates aside from a reddit post by Rivian's VP of software development [XXX] ). Rivian has no estimated time to have a solution in place. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Software update rolled out version 2023.42.0 and now the vehicle screen is black and HVAC does not work. It is unclear if any safety or airbag systems are operational. Cameras not working.
