Just found this came out from GM on 2/5/2021 General Motors has issued a Technical Service Bulletin for a wide selection of 2019/2020/2021 model year vehicles that are experiencing a no-start or long crank condition. This includes the Chevy Silverado, GMC Sierra, Tahoe, Suburban, Yukon, and...
After 10 min in the middle of no where with no help around I disconnected the battery let is sit for 5 min the reconnected and it started???
This has happened twice in the first 2 weeks going back to the dealer as soon as my trip is over.
Anyone have this happen?
Just purchased a 21' GMC with the Elevation PKG last week.
So this happened 2 days in I go to start it step on the brake hit the start button and the engine just cranks for 10-15 seconds and does not start.
