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

Tue, 26 May 2026 06:02:02 -0700

when the engine is running, my brake pedal goes to the floor. when engine is off, I can pump up the brakes somewhat. I have changed the master cylinder and there is no fluid leak. Could the problem be with the power assist boost, or is there something else that could be the issue?

2015-Present GMC Yukon: My A/C is going from hot to cold and back A/C no longer blows

Sun, 17 May 2026 18:40:49 -0700

I drive a 2015 Yukon SLT

So I just started having an issue or my AC is blowing cold, but then starts to blow warm, but then starts to blow cold again. I noticed my cooling fans only work when my AC is on, but never engages to the high speed. It should after reaching a certain temperature. I had someone use a scanner to automatically turn on the fans to high and they do work but at the same time this happens my back, A/C doesn’t blow at all no air comes out. I change the sensor that’s on the line. No change. The guy who scanned it said he was getting a bunch of HVAC issues. But also got a code that said no communication with the Telematic control module. He said that could be the issue that’s causing the fan to not turn on high and for the back fan not to work at all but everything I’ve seen online says there’s no correlation. I don’t wanna buy the module if there’s no correlation any help would be great.
