Consumer Description

The OnStar vehicle locater, GPS maps, clock (auto update) are not responsive as of the 2nd week of December 2025. My truck cannot be located via OnStar, I cannot use the GPS Maps for directions, and the Clock reads 12 minutes fast when I put it into Auto Update mode. Reported to my GMC dealer (Elizabeth City GMC, Elizabeth City, NC 27909, and had in for service 3 times without correction of the issue! The dealership conducted a Software System Update which cost me $400.00, and still did not correct the issue. I spoke with OnStar three (3) times to try and correct issues but they did not resolve the problems either. OnStar stated it is a GMC issue............My last service at the Elizabeth City GMC dealer the Service Tech stated the OnStar Module is bad and requires replacement, and stated it will be an additional $550.00 +/-!!! Please advise and assist in further action I can take as this issue should be a Warranty issue and replaced by GMC and/or OnStar!!! Class Action Suit in line! Thank you.
