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.

Owner report 11431865 · 2021-09-06 (September 6, 2021)

The driver's side seat failed. Due to a seat electrical harness failure the seat became stuck and neither the seat seatback or headrest could be moved. I could comfortably still reach steering wheel and pedals but my wife could not safely do so. The car has approximately 36k miles on it. I paid to repair this $831 negotiated down from $1600+. This is a pressing NHTSA issue because on the repair invoice the technician noted that a 40 amp fuse had been installed in a 30 amp socket. Presumably it came from the factory in this condition.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
