Daughter is currently having this same issue, with steering wheel. Sitting at dealership. Mechanics couldn't figure out the problem so they called GM. GM Suggested... that both positive and negative battery cables be replaced. Now mind you it'* a suggestion, not saying it'* the problem. And 2...not covered under her GM certified warranty. Who wants to spend almost $500 on a suggestion? I would be interested to know if anyone'* steering problem has been fixed.

This thread is 10 years old.

Post #1 and #2 are from an old thread that appears to describe the same issue.

Check out this post from the old thread for a GM explanation of the issue and the extended warranty that they had for it.

Based on the other thread, I'd guess the steering rack is the problem. The steering column isn't likely to do this, nor is the steering joints etc.

But just to be thorough:

How many miles on the car?

How many miles has your daughter owned it?

Has it been in any accidents etc.?

How old is the battery in this car?
