NHTSA Complaint #11464292 — 2008 CHEVROLET HHR

Steering gets very stiff and sometimes locks up when turning left or right in a curve at highway speeds. Had dealer check it and they said they replaced steering motor. Did not correct problem. Made an appointment to check again but was told I would incur charges. I have had it to several mechanic shops and we cannot find anything loose or failing. In a parked position it locks up completely until you start rolling. Afraid steering is going to lock up in a curve and cause harm to driver and passengers. It is available for inspection. It has not been inspected by the manufacturer, police or insurance. Has no warning lights or messages pertaining to problem. The problem first appeared approximately 6 months ago.
