What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The steering adjustment moves in and out but will not move up or down. You can hear a clicking noise like itâs trying to move but nothing happens to the steering column.
The warranty was previously extended on the system but I am outside of the mileage window but inside of the time window. I have $6000 in repairs so far and am trying to get assistance. I have been dealing with issues since October 2024
It started to smoke a gray smoke coming up from under the car on the passenger side of the car over the front tire. I do have pictures. It smells as if it is about to catch on fire. The car never had any problems before this botched repair. Now they say they cannot find the problem.
This is a manufacturing or design defect which will likely as here, cause failure and could possibly at least to my non electrical engineer's mind cause fire.
When driving, the steering wheel locks and I can no longer steer the vehicle, it locks in a way that I cannot move the steering wheel at all, which may cause me to crash if I am at a dead end road and need to turn. I have been trying to contact the manufacturer for resolution but have not received any responses.

When starting vehicle, or often when driving down the road, cruise control, adaptive steering, lane assist, blind spot detectors, pre-safe braking features will all become inoperable and throw multiple failure readings on dashboard.
