Here's What My Service Dept Says.....
.....today i received a call from the Service Manager at my local dealership to tell me that he spoke with Tech Assistance himself and was told that while they have had a few complaints of the same nature as mine, GM has not yet been able to duplicate this in tests of their own. i asked about the claim of duplicating the situation by turning the wheel 'lock-to-lock' several times (maybe as many as 20) and it locks up. he told me that if that were the case, that it really wouldn't help diagnois the problem as this is not 'normal driving conditions'.
my service manager continued by telling me that the "EPS" (electronic power steering) System is comprised of several components; B.C.M. (body control module), P.S.C.M. (power steering control module), Torque Sensor, Wheel Position Sensor, Electric Motor and Steering Column. the Steering Column assembly includes the Torque and Wheel Position Sensors and currently they are not available separately. in some of the cases GM has had, the system has set codes which the techs have been able to retrieve. and, in some like mine, no codes were found. in the ones that DID have codes, they were instructed to replace the Steering Column assembly. in those vehicles, they have NOT had any further complaints about the same issue.
therefore, he offered the following; 'As Service Manager, i can authorize the replacement of the steering column in the interest of Customer Satisfaction since it IS a safety issue, however in doing so i cannot guarantee that this will correct the problem since we have not been able to retrieve any codes from your vehicle or actually duplicate it ourselves.'
again, i suggested that we 'wait and see' as i would rather be sure that a repair is the correct one than only find out later that 'ITS STILL THERE!!!'
just thought i would share that with everyone........so i suggest that if you would feel better about the situation, ask your SERVICE MANAGER, not service advisor, but the MANAGER, to authorize the replacement of the Steering Column assembly in the interest of Customer Satisfaction and especially since it is a SAFETY ISSUE.
with any luck, after GM receives a few more 'possibly defective' steering columns on which to perform an 'autopsy', they will be able to determine what is failing and notify all affected G6 Owners to have the proper repairs made.
