What year was your truck?

 

2018

 

I got my letter last week as well. That's a long time to cover these parts, but I'm happy with that. Mine is a 19'

 

Does that cover engine damage when the tips crack off?

 

The letter didn't go into any detail, that's why I was curious.

Does anyone know if this was all brought about simply due to the glow plugs themselves failing? Is the glow plug controller an issue? Or anything else?

15 years is a lot. I know they did something similar on the LMLs but not 15 years.

 

Got my letter today. Sweet, I'll take the 15/150k warranty.

Doesn’t it look like postcard with adversity or a 11x17 letter? I haven’t received mine yet?

I got mine today!

 

…. I’d like to know if any forum members have had THIS ISSUE and what happened; what was the CURE???

 

My 2017 was eating glow plugs. They replaced the GPCM and since then its rate of glow plug consumption has declined, but not quite to zero.

 

It's been my single consistent issue with my 17. I've had 1 failure every year since new. 93k on it now. Just went in sometime in April for the 4th failure.

Changing glow plugs is as easy as changing spark plugs. Maybe it would be beneficial to just change them all at the same time and get it over with

Got this letter last week for the 2018.

 

I have a 2013 LML, had 2 plugs go bad and paid to have them replaced. Didn't know about any extended GM warranty. Can anyone confirm the plug warranty for a 2013? And wondering if I can get reimbursed by GM?

 

Bumping up. Anyone?

 

I think the warranty is up on your 2013 model. It wasn't 15 years on the LML trucks. I think it was 7 years maybe? I had the letter on my 2012 when I bought it and had a couple plugs replaced under warranty but that was back in 2017.

 

My 17 has gone thru 6 in the past 2 years. Paid for the first one then did the next 4 myself. Just had it back at dealer for latest one and got it covered under warranty. Called GM to try and get reimbursed for previous repairs and they are telling me the extended coverage doesn't show up with my VIN. Guess I got a freebie from the dealer.

 

I have said a contributor to failing GP’s is low voltage and high amps from batteries… BUT!!!!

the primary issue is the GP controller….

nearly every failure has been when I go from off to crank without pause at “run”… especially when cold.

 

Uggh. I'm sorry you had so many glow plug issues. I had hoped GM had them fixed by the time the L5P came around but it does not appear so. How many miles did you have on your truck when they started going out?

 

I have the same issue with my 2017 L5P, I only have 59000 on it. I got one replaced last week, cost me 500 bucks ans it was now out of warranty. The check engine light is back. This will make #7 for the life of the truck. I will most likely chance it myself.
I sure hope the extended Warranty is expanded the 2017s.

 

$500 for a glow plug? Must have been one behind the EGR. Otherwise it's a $30 plug and a 30 minute job.

 

It was 2.5 hrs labor. So it must have been that one Thanks! I am taking it in this afternoon to get code checked etc.

 

So I have a #5 glow plug fault on my 2018 Chevy. It’s at the dealer now getting replaced. The dealer informed me that it is covered under this extended warranty however they must do a software update for the glow plug controller that is not covered under the warranty. I find it odd that follow-on mx and/or software updates for this related problem is not covered. Has anyone experienced this or is this BS?

 

I have had glow plugs replaced in my '18 under the extended warranty without having to pay for any programming.

 

A couple years ago, we had cold weather and 3 trucks in our community of around 15 trucks had 3 failures of the #7 GP. Silly to think it’s a “problem”???

 

I have a 2012 GMC 2500 HD diesel with 69,800 miles on it (I don't go many places very far away). I bought this truck used in 2015. Glow plugs started failing on my truck very early. I'm a do-it-yourself guy and after going to the local parts store to have them put their meter on the truck I learned my "check engine" light was telling me a glow plug circuit had failed. I took the easiest route and bought a new plug from them and went home and went to work. Removing the wheel well plastic cover is the toughest part of the job. Once that's out you have pretty easy access to the glow plugs. I had changed at least three plugs in a very short period of time when I had a failure of the diesel exhaust fluid reservoir.

The shop I go to for GM cars told me the tank heaters fail when the weather changes to cold but he thought there was a factory warranty that covered that repair. He called the local dealership for me and learned the tank assembly was covered for replacement at no cost to me under a special factory warranty. The dealership gladly replaced my defective unit and also informed me there was an extended factory warranty on the glow plugs, as well as several other items.

At this point I've had all 8 glow plugs fail and several of them have failed two or three times, but I was able to have the dealer change them until I exceeded the 10 year time limit. The warranty on my truck was 10 years and 120,000 miles. I had never heard of such a thing. Plus, I was getting real good at changing them myself by the time I learned of the warranty.

So my advice to anyone with a vehicle like ours; go to a dealer and ask the maintenance manager to look up any information he has regarding special long term factory warranties on your truck. It is no skin off the dealer because it's all paid for by the factory, so don't be afraid to ask. My dealership, namely, Future Chevrolet of Sacramento, was more than happy to help me.
