issue No Start

[TJay74]

Back pressure valve is at the rear of the exhaust system, right in front of the rear passenger wheel. The other cause of no start has been said to be too much grease on the contacts in the starter from what one members dealer found. They said over time the grease will wear down and the issue would go away.

-4 this morning and used the remote start. New starter worked right away.

Had it towed in to the shop (hooray for OnStar), and they told me that it was an Ignition Control Relay which had to be ordered in from Montreal. In the meantime my truck was left in the lot in -20 and below, and it started right up for them. They got it in the shop and replaced the ICR. They kept it for another day and left it outside so they could test it with a cold start to determine if they needed to replace the starter/battery.

 

Truck started right up. We're now 3 days into having a new truck with no issues. I'll report back if it happens again or if there are any further issues.

 

In short, get them to replace the Ignition Control Relay.

Seems as time goes on, there are more and more reasons that they don't start haha

It’s not just a cold weather thing - 73 degrees in Columbus Ohio at a gas station. When I got back in the truck and tried to start it - got a click then everything went dark.  No instruments, no radio, FOD would not remote start, lock, or unlock doors - nothing.  Had two people try to help me with jumper cables - no luck.  Being Sunday my options were a wrecker or call my friend the mechanic.  I called my friend first and he recommended looking for loose connections on some plate mounted above and to the side of the battery.  There was this blue clip which had two separate bundles of wires towards the back of this terminal or bus thing mounted over the battery.  On side of that blue clip had some play in it and as I moved it side to side I could feel in sliding over the male side of this thing.  I hit the lock button on FOD and lights flashed - the truck started and has started about 5 times in my driveway since then.  Trying to figure it out, I started searching the internet and discovered recalls on my 2014 (bought it new in 2014) and see 15 recalls ranging from seat belts, loss of brakes and steering, seat belts, air bags.  Why haven’t they fixed these issues at service intervals?  I tried to tell them about no brakes and how I almost hit a car in front of me and close call rolling off a cliff  with no brakes.  What the heck GM?  Are you guys trying to make a killing by cutting corners??  Now I know not to by an American made truck that’s made in Mexico

Fun fact, tons of us are rolling around with open recalls because you can't even get those done with parts that are not available.

 

Poor dealership service if they don't notify you about recalls that could be done, it's also partly your job as a vehicle owner to maybe inquire about said recalls. Usually best to print those out so they know what you're talking about.

 

Can't really blame it all on GM here, it's the dealerships fault as well. Plus you have a "modded" vehicle per your other post, maybe that is why they don't do some of the things but who knows.

Yep, I regularly check the myChevrolet app to check for anything new ... I always get this, meaning any old recalls have already been rectified and there is nothing new, as well.
Not sure why it came up as an LD but it is what it is.

Well, some dealers, cough cough, Honda/Toyota, cough..*not covid* will notified you via mail multiple times regarding the recall. If it's a recall that could lead to death, they will keep mailing notice and keep CALLING you as well. They won't stop until you declined or it's been remedy.
