Read by machine from the document NHTSA serves (5 pages), read Sep 30, 2026. A part number is shown only where it matches Chevrolet’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 11 complaints with NHTSA since 2015.
My Onstar feature does not work at all. So there is no emergency notification in the event of an accident. The dealer ordered the module to repair the problem but GM keeps canceling the order. There has been reports of the engine stalling, I have not experienced that yet so I do not drive the vehicle much for that reason
