Sierra 2500

  • miles
On or about [XXX], the Transmission Control Module, FAILED, on my 2011GMC Denali 2500 6.6 diesel. It was a KNOWN faulty part.General Motors was aware of the issue years ago. This part should have been deemed a Safety Recall item. Imagine, pulling a trailer down a busy Freeway, with Semi's presence. Module goes out, truck goes idle, people hurt or worse. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
