What owners say
Verbatim reports filed with the United States safety regulator (NHTSA) by owners of this exact model year. Public record.
Kept going in for repairs for the same concerns - nothing was found —- now its a recall on the 2022 model for the same issue that my 2021 model has —- Malfunction in the front/ rear differential lock system malfunction.
The lane keeping assistance is WAY to sensitive. Several times at just the slightest move towards the shoulder the car will brake and swerve. Its very alarming and needs to be recalibrated.
