Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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. …”

“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. …”

“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. …”

“I received a critical safety recall regarding side air bags from Rivian regarding my 2023 R1S on June 14. After multiple attempts by me to connect with their Customer Service, I was informed that a mobile service technician would come to fix the issue on August 26, 2024. This would be more than 60 days after Rivian's initial notification. Additionally, on July 6 2024, when I turned on the vehicle, I was notified of multiple system failures. I promptly created an incident ticket with Rivian on this but have to yet hear back from Rivian. …”
