2014-Present GMC Sierra: Intermittent no start 2016 GMC Sierra 1500

Thu, 25 Jun 2026 15:19:56 -0700

At random times my truck will not start. When I turn the key on, the dashboard lights but no crank, no sound. If I keep trying it usually starts after several tries. On a few occasions it cranked Just as I was releasing the key from fully turned. It was a week before it happened again, then worked okay for a month. I brought it to my usual repair shop but they couldn’t diagnose it because it started every time they tried. Drove okay for another month. Next time it failed I had it towed to the same shop. They have been trying it for a week but it starts every time they do.

Any thoughts about what could be causing this? Next time it fails I plan to take it to the dealer. 2016 Sierra 1500
