Example complaints

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

“The lane keeping feature will randomly cause the vehicle to veer towards the center line at a variety of speeds and under a variety of conditions, requiring immediate driver correction to avoid crossing the center line. No accident has occurred but the system is now deactivated. In addition, the collision avoidance system does not reliably acquire a vehicle ahead if that vehicle is stopped and the speed differential is >30-40 MPH. Without driver manual braking, a crash would occur.”

“I just leased a new '21 Crosstrek Limited. With only 90 miles on the car, while driving on the highway using the adaptive cruise control and lane keep assist, the vehicle started aggressively jerking over towards semi trucks (while going 70mph)- I had to give significant input to not be pulled into a semi truck. I turned off the feature then turned back on. Again, it was hard jerking only towards semi trucks. Drove back to the dealership. Their mechanic took for a drive and said the exact same thing, that it was sketchy and jerking towards semi trucks. …”

“Check engine light came on while driving. All Advanced Driver Assistance Systems were disabled. Code is P26A3: Thermo Control Valve is faulty. This is a known problem and Subaru has addressed it by redesigning the Thermo Control Valve in 2021. Unfortunately there is no recall on the models fitted with the prior design that have a high rate of failure.”
