2019 Blazer RS won’t start

Make sure all the cables connected to the battery are corrosion free and properly secured. Particularly the ground wire. Also, make sure the Fob is in close proximity to the console and use another Fob to rule out any issues with the Fob. I am assuming when you said it won’t start that when you push the start button nothing happens. Is that what’s happened?

I have not had that issue. I have left my Blazer sitting, while I drive my other car, a few times.

thanks for the reply. My blazer is currently at the dealer who is checking it out.Hope they find something.

Do you get your gas from the same station? Might have something to do with that. If you do, maybe try a different station...

never experienced this one so far.

Does anyone have trouble not being able to start car after it sits for a few days. This has happened to me twice. But after waiting about an hour it does start! Not the battery. Both times my car was at home in the garage. Don’t want to get stranded out on the road because car won’t start. Any ideas? Thanks

I just had my first problem not starting. Went to start my 2019 RS blazer and nothing . Waiting for dealership to open so it can be towed. Not very happy.

With the stay home orders due to the virus, my Blazer sat for a full week without being started. I had no issues. It ran a little rough initially but smoothed out as it warmed up. I thought the battery may have drained a bit from sitting so I expected the auto-stop to postpone activating for a little while. Nope. It worked the same as it did before the lockdown...

Dealership just called , they said bad battery, installed new battery. I guess we will see what happens next. I drive Blazer everyday I told dealership makes no since brand new to go bad.

Was it replaced under warranty? Dying in under a year seems like it was defective. At a minimum, I would expect you to get a pro-rated discount depending on the warranty.

Fully replaced under warranty. Blazer only had 10,000 miles

I have a 2021 Chevy Blazer RS 13000 miles on it, I had it to the shop the first time because it wouldn't start then when it did it was in limp mode, the second time it wouldn't start had it towed in, and now this time{3rd} it is sitting in my garage trying to crank but does nothing, also had a problem with it at low speed accerlation jerking like it was running over the side of the road rumbles. I have had nothing but trouble out of it, can't trust it to take it anywhere seems like it acts up every three months. Not happy with it, it looks great but looks doesn't get me where i need to go.

I'm sorry to hear that you are having so many issues with your Blazer. Might be time to look into the Lemon Law. Unfortunately lemons happen to the best of manufacturers. My Blazer is about to turn 20,000. It's been very reliable so far (knocking on wood as I say this). I hope you can get it resolved soon.

Dealer Replaced that positive battery cable. 2020 Blazer.
I was stranded on busy road during rush hour, Waited for tow truck and called local police to get behind my vehicle to avoid any accident. GM has responded that I was never in unsafe situation!
