PROBLEM DETAILS

Steering lockup and Direct Adaptive Steering malfunctions

Steering wheel becomes difficult or impossible to turn, including at highway speed

Check engine light: On

Dozens of complaints describe steering lockups, Direct Adaptive Steering (DAS) malfunctions, power-steering-assist failures, and the steering wheel becoming difficult or impossible to turn, several while driving at highway speed. Documented consequences include a flat tire triggering total loss of steering control during a lane change resulting in a collision with an 18-wheeler, and a steering module failure after a minor bumper impact that led to the vehicle being totaled. One owner reported three separate steering-control computers replaced and expressed explicit fear of a future accident.
