Is this the dreaded lifter issue

[peyc2]

Hello all,

this is my first post. I have a 2021 Tahoe Premier with 8,600 miles on it. I got it November of 2020

today, suddenly at a traffic light, the auto stop/start came on (normal), but after about 1 or 2 seconds, the engine started, and when it did, it was misfiring, and makin a noise
from the drivers side. when i moved from the light, the engine was misfiring, and gave a thud of a backfire.

I nursed it home (all of 2 miles) and i shut it down. No error codes I waited about 5 minutes, and when i remote started it, there is a load clacking noise, from the drivers side
of the engine. when i lifted the hood, it was really bad.

I called my dealer, and they said to not drive it, and get it to them.
I contacted OnStar and they have a flatbed coming to my house in the AM.

Is this the lifter issue?

I haven’t experienced it myself but that sounds a lot like it.

Sounds like a lifter and bent push rod Keep us posted.

Sounds like a lifter issue. Keep us posted on what happens.

Ok,

so the dealer just called me, and they listened to it. it is the lifter issue.
They have to order parts, once they have them, about a day and a half to install and then test the car.
Of Couse parts are on a delay, they do get them, and can take a week.

The dealer also informed me that GM, will reimburse a rental car, at the rate of $44.00 per day, but the caveat is it must be a GM vehicle.
Now the conundrum is finding a GM car that is rental. The only thing I can find, is a Tahoe, for $77.00 per day. Yikes.

everyone around me do not have any cars, yet alone a GM product.

That’s weird…too bad they couldn’t provide one.

I know at one time Avis had a lot of GM vehicles…not sure if that’s still the case today.

The rental car issue is a PIA
I found a 2020 Tahoe at the 4th Enterprise I called and of course it’s $70.00 per day but it’s all I could find in a reasonable distance from where I am and need to go

The whole thing took most of the day
The only good things are the towing company was great they billed Onstar no no money out of pocket on that other than a tip. And the dealer service department and the service writer were very honest and easy to deal with so even though this is a major inconvenience it was not a bad experience other than annoyance

As a member of the failed lifter club, the whole process from a customer's perspective is flawed. I am drafting a letter to corporate and will include my log of the conversations and such along the way. While GM customer service may have been polite, the response was inadequate. While the letter will probably go on deaf ears, at least I will feel better!

I went another step
i wen to the NHTSB and filed a safety issue. My complaint is this should be at the least a caution letter to owners about what is happening. Lucky for me I was on a medium highway, and not 700 miles from home on 95 going 65 MPH when it failed.
At the least this could cause an accident, or trigger one for vehicles behind if you stop suddenly.

We were 250 from home but the engine kept running so we didn't stop. We were fortuneate to make it home. I will do the same with the NHTSB

I'd run it till it grenades all along the boulevard and get a new engine.

the lifter debacle continues......
gm just released a notice that lifters are to be replaced on both banks on current vehicles on the lot and those en-route to the dealer before they are sold/delivered.
as of today dec 2 2021

Unreal. Their Corporate response to me in addressing my lifter failure at 12,995 miles on my 21 Denali is “we’re sorry you were inconvenienced and understand your frustration. Please accept 200,000 My GMC Rewards points to feel better.” My repeated requests for an extended powertrain warranty were denied as was my request to have the remaining lifters in the engine replaced. I’ll get a sweet deal on some OEM GM accessories though, oh boy!!!

Happened to me on my 6.2L Sierra Denali 3 wks ago at 11.400 miles. Same thing, driving down the road and engine started making noise and warning lights came on. Lucky i was about 1 mile from my dealer so I drove it into their service area. Tech who came to look knew what it was right away when he started it, yep collapsed lifter for sure. In 1 hr they had a scanned code of P0305 and had removed valve cover and found bent push rod/collapsed lifter #5 cyl. He also informed me new rental cars are n/a so they have a 2014 Equinox for me. It was a low miles AWD in very good condition (local trade-in). Anyhow, 1.5 days later I had the truck back. I was shocked they had all parts in stock and tore into right away. Have to give the dealer credit for great customer service.

I just checked with a good friend who is parts mngr for Chevy/GMC dealer and he says they got no such notice as of today! He searched everything the got recently and nothing. They have about 10 V8 trucks on the lot and nothing stopping they from selling them. Someone was even picking up their new Trail Boss when I was there 1 hr ago. I trust he would tell me the truth as he has no loyalty to the dealer. Any chance you can provide a copy?

I was thinking of a new Tahoe but decided to keep what I have. My 2015 LTZ has every option possible but now at 110k, so with all this chip shortage, lifter issue I guess I will hang in there a bit longer. Keep us informed on how this ends up for you.

Showed him that link and said he look into it next week. But they only have parts to do one vehicle, GM won't send them more parts than that.
