Uh oh...towed to the dealership at 29K miles

[5280YUK]

Went to pass somebody last weekend and heard a pop while accelerating. Initially just thought something was in the road but came to a stoplight shortly after and the idle got REAL rough, almost like it was going to die, got even worse on acceleration. Drove fine when not at a stop/idle. CEL was flashing and steady traction control light. Smell of gas like odor when I finally got it home. I called dealer and they advised not to drive it, so had it towed to them and currently waiting diagnosis.

Bought it certified used so came with 12 mo/12k warranty. Hopefully whatever it is, it's all covered.

That sucks......at least it's under warranty though. What year is it?

It's a 2018. Sure warranty will cover it but won't be at ease until they say so.

Update: Dealer says exhaust manifold. Good news is covered under warranty, bad news is they are saying they are having a hard time finding parts so no time frame for the fix. When I asked about a courtesy vehicle, they basically said they didn't have one. Told them that since it was CPO, I should get a courtesy vehicle, they are now pawning me off to management. We'll see how this goes....

Pawning off to management isn't too terribly bad. If that manager doesn't address your concerns about your issue and situation then go see that person's manager. Same with that person...keep going up the chain. Hopefully some manager and maybe ultimately the owner will take action. Just be non-emotuonal, logical, yet firm. What you're describing is understandable but you should not be left without a vehicle just because you bought from this dealer.

that's a odd one I drive the life out of mine and have for years and never had a issue with oem manifolds, headers on the other hand nothing but problems I have cracked and broken a few, so much that I gave up on having headers. I have had the exhaust manifold bolts break and cause a leak at cold start but that's about it.
Never heard of a oem exhaust manifold giving up the ghost, not on a v8 GM anyway

I agree, that is really strange.

Thanks for all the replies.

The dealership that it's at now is not the one I bought it from which is why I've been patient and understanding. I read in my paperwork about the CPO loaner vehicle so I asked about it since if this is going to take a while, being down one vehicle might start to impact our schedules.

Also thought the diagnosis was strange so I asked the person who I thought was my service advisor, since she is the only one I have mostly spoken to, for a copy of the paperwork/diagnosis (mostly so I can also try to search for this part that apparently is nowhere to be found) instead of saying she'll email it to me she asks me, who is your service advisor?? I was like, ma'am, you are the only person I've talked to so if there is someone else that I should be speaking to, please re-direct my call. She told me that persons name and that they were on the phone and would call me back, never did. I tried them yesterday and they were off, so trying again in the morning.

This whole situation is beginning to make me nervous.

You said it ran bad but never mentioned anything about exhaust noise. Was there any extra noise? The manifold problem sounds suspicious.

 

[5280YUK]

Right, I never heard an excessive exhaust noise which is why I'm concerned.

Now that I think of it, the lady I've been talking to said that the exhaust is one of the major parts needed for repair that they can't find. So I'm wondering if the actual problem isn't something else? Which is why I asked to see the paperwork/full diagnosis....

I would call them back in the morning and if you still get any kind of run around ask to speak to the "service manager", that will be your go-to guy unless you need to higher up which would be the dealer general manager.
or better yet when you call in the morning typically you just get a receptionist who ask how can i direct your call? and just ask for the service manager.

Appreciate it, that will be the plan.

Exactly! I am still not buying the original diagnosis but I could be completely wrong.

 

[OR VietVet]

You have a right to see the complete diagnosis of the problem, warranty or no warranty. There is just something about this story that is not complete.

If that still doesn't work since they have a bad habit of not returning calls no mater what their position in the company is, typical Dealer BS, then I would drive my happy a$$ down there and find out whats going on.

 

[OR VietVet]

They would not want me showing up if they are ignoring my calls and messages.

I have been out of town for work and while out of town, spoke to my supposedly true "service advisor" who still wasn't very forthcoming with info but he did tell me it was code 0300. When I looked that up (misfire) seemed more like what I had experienced and I still couldn't put together how the exhaust manifold has anything to do with it.

I got back home last night and decided to pay them a visit this morning...

I began talking to my "service advisor" and as he was trying to figure out who I was, as I was explaining who I was, another gentleman who I believe was the service manager interrupted and said he could help. He proceeded to tell me that the lifters are being replaced and one part they need is on backorder, can't remember the exact name but it was oil manifold or something like that??

Anyway, he was obviously way more knowledgeable about what was going on and apologized for all the miscommunication. Parts MIGHT be in by the end of next week and hopefully have it back the following week.

I felt better when I left but will feel even better when I get it back.

 

[OR VietVet]

So, the word "manifold" was the confusion? Thought was exhaust but is actually a manifold having something to do with the oil flow? They should come right out and tell you, dammit. They should have documentation already about what problem is and the needed repair.

Lifter manifold oil assembly (LOMA) which controls the AFM. Makes sense seeing as you had AFM issues and misfiring. Probably just got lost in translation...

Yea, I knew an exhaust manifold problem/broken, just did not make sense to me and others here.
