Have you exceeded 36k miles?
If not, see a Chevy dealership.
Have no idea what you mean by "pip5653k"?

PIP5653K is a technical service bulletin which advises the dealer on how to correct a problem.
There appears to be an earlier version that explains how to correct the problem. Ask the dealer why they didn't follow this technical service bulletin.
