Dealer has had my '15 Denali for 3 months. What should I do?

[tdowns12]

Took my 15.5 Denali to the local dealer (SE Michigan) with a CEL on 5/19. Diagnosed as a fuel injector issue. I had my injection system replaced in Feb'19 so, I was surprised. Dealer gave it back (and charged me $900) to me on 5/30. Drove it to work the following Monday, immediately threw another CEL and went into 'limp home mode'. Dealer has had it since, claiming they can't get parts out of Pontiac. I've opened a case with GM customer service but they're not helpful.

What would you be doing if you were me?

ask a lot of questions, dude where's my car?

 

[kurtibm]

Also ask for the part number(s) of the so-called unobtanium part(s) and do some of your own homework; or more likely you will call their bluff merely by asking.

Does the dealer have an incentive to hurry up? Giving you a loaner car for example. If they haven’t, I would demand one.

I would go check on my truck after three months. Maybe it’s lost or damaged?

I would have pulled it out of there and fixed it myself or taken it to another dealership.

Call a lawyer, that's just WRONG

Wow. These responses are something. If the parts are on back order, that isn't the dealer's fault and no other dealer will be able to get them either! It sucks but I don't know what you expect the dealer to do, build a plant in the back lot to manufacturer just the part you need? Hopefully they've given you a loaner or rental on GM's dime so just keep driving that.

If you're the original owner you may have a buy back case or depending on the laws in your state you may still have a case even if you're not the original owner.

No one here can really help you since you didn't say what part(s) is/are on back order either.

Researching pipe bombs on someone else's computer.

Seriously, that's way too long. Someone above said parts may be back ordered, but that's still an excessive amount of time unless there's a super secret part that's hand made in Wakanda out of vibranium.

I would:
Get them to give you the part #
Call another dealer(s)
Ask them about the part

If another dealer says no problem:
I would find out what state the truck is in now (taken apart, can it be driven, etc.)
Request that it either be completed immediately...
Or put back together (if it's not) and take it to the other dealer

In my experience three months is completely unacceptable.

I’m in your area, just curious who the dealer is. Send me a private message if you would like to share the name of the dealership.
There are many comments and suggestions here, but one I would seriously worry about is damage to your truck. A couple of sagas over the years in the vette and Camaro forums regarding extensive damage caused to vehicles at the dealership, and them attempting to buy time by claiming back ordered parts. Walk in unannounced and see your vehicle.
Otherwise, a face to face meeting with the general manager and/or the owner of the dealership is the next move here. I’m assuming you have no rental from the dealer because you’re out of warranty. An entire summer without your truck is long enough. It’s time they give you a real solution

The dealer's thesis strains credibility. GM builds thousands of these engines every month across the Denali and truck lines. What part would take three months to source on an engine that's still in active production?

I agree with the advice to walk in unannounced and ask to see your vehicle. While you're there, ask to have a conversation with the GM of the dealership. Keep your cool, ask for a more specific explanation of why the repair is taking so long.

This would take an hour (who has time to stand outside the dealership with a picket sign?), and you'd probably know a lot more at the end of that hour than you do now.

Uhh. A part that’s on back order...

Went to the dealer this morning. There doesn't appear to be a timeline for getting my truck back. It's on a lift which shows some thought is being given to its condition I suppose. But, the block is exposed which always worries me and I'm not sure what dangling for 3 months is going to do to the finicky suspension parts.

Anyway, the story is that the head gasket on the '15 L86 (GM part #12700877) was discontinued and there are apparently none left in the known world. A cursory google search didn't turn up any online options with the part in stock. One site listed it as "special order item" and the rest listed it as discontinued.

BBB. That would be my next call, then, after they call you within 3 days, decide about meeting with a lawyer before or after lunch.

 

[Blueinterceptor]

If the gasket is discontinued, aren’t there laws regarding parts availability for 5 years or something?
If the engine is the problem, seems like gm should stand behind their product and put a new engine in. It’s nit your fault gm had a design flaw.

 

[91RS]

Ah, I guess the lawyer will build the factory to make the head gasket!!

I’m not trying to make light of your situation because it does suck. This place is full of great (not) advice from the conspiracy theorists that will only get you more stressed out and won’t help. Unless you want to try and get the truck bought back, contacting the BBB, a lawyer, Trump, whoever will not magically produce a part that is on backorder. It’s all a waiting game at this point. I had to wait months for a transmission to be manufactured for my Cobalt SS years ago that was backordered. There is a process that takes time when a part goes on backorder, which could be caused by all kinds of reasons that can’t be foreseen.

Is this thread real?
I'd collect my car and take it to another dealer.
