There are 3 owner-reported driver assist & adas complaints for the 2023 Rivian R1Tin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
When driving on the highway with ADAS on with lane keeping assist turned on with software 2024.39.01, the truck would constantly pull me back into the center line even if I were not close to the white line on the road. This is very concerning as on a two-lane highway, it pulled me over the center line and towards an oncoming traffic. The latest software update seemed to make it more sensitive, not allowing "ping-ponging" and trying to keep the truck almost too centered, as other cars I have are not this aggressive. I ended up turning off LKA, but that should not be the solution.
The vehicle’s Driver+ advanced driver assistance system (including Adaptive Cruise Control and Highway Assist) repeatedly failed during normal highway driving. The system would display “Driver Assistance Features Unavailable – Service Soon” and immediately disable all assisted-driving functions, even in clear weather and well-marked lanes. This occurred intermittently from approximately 1,200 miles onward and continued for over a year despite multiple repair attempts by the manufacturer’s service centers. The malfunction directly affected safe operation, as the system could disengage without warning at highway speeds, forcing sudden driver intervention. The issue was reproduced and documented by the manufacturer’s technicians during at least one service visit, which resulted in replacement of the vehicle’s driver-assistance computer. The failure continued even after that replacement. The vehicle has been inspected and serviced numerous times by the manufacturer, with diagnostics performed on the cooling system, cameras, sensors, and ADAS module. Each repair attempt either failed to duplicate or failed to permanently correct the defect. The safety risk is loss of Adaptive Cruise Control and Highway Assist functions while driving, unexpected disengagement of automated steering/braking, and lack of reliable warning timing to the driver. Warning messages appeared frequently throughout 2024–2025, beginning within the first few months of ownership. The defect remains unresolved and appears systemic rather than isolated to this vehicle.
Rivian issued an OTA update, 2023.42.0, that rendered all but the most basic functions disabled. There is no center screen. No ability to control defrost or climate in the vehicle. All advanced safety features, other than blind spot warnings, appear disabled.
