There are 2 owner-reported brakes complaints for the 2023 Rivian R1Tin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Car was lane corrected into other lane and started accelerating. Like getting hit by a bumper in a pinball machine. Avoided a head on collision but managed to safety maneuver into a fence instead of a tree.
The vehicle was parked on a 8 degree slope in the driveway with approximately 2 inches of snow on the drive way. Within thirty minutes of the vehicle being parked the truck slide down the driveway and crashed into the house. The parking brake failed and or is miss-engineered seeing that only two of the wheels were locked and two rolled noting the tire tracks in the snow. The saftey of myself and others could have been much worse if the truck hadn't hit the house and kept rolling down the hill into an adjacent street or house. There is other vehicle reports of this happening on online forums. The vehicle component has not been inspected by the manufacturer. The issue lies with it being an electrical motor and does not have a differential to lock the remaining tires as in an automatic gas powered vehicle. This company has relied on the parking break to only lock the rear wheels for the parking break despite it being an extremely heavy vehicle.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
