So my 2015 Sierra out of no where just encountered engine problems.  Cylinder #4 lifter went bad, bent push rod and they had to replace the cylinder.

 

Has anyone else had this issue?

Close, not sure of which cylinder, but had a broken push rod. Dealer did tests and found abnormal wear on the cylinder walls and are replacing whole engine per GM. They said that the only broken item was the push rod.

Have you had any issues since it was repaired?

Still do not have the truck back. Will be a total of 18 days without it. Should have no issues with a brand new engine, but if things were not put back correctly, who knows...............

Good luck with everything buddy.  I didn’t have mine for a month so I feel your pain!

Any problems with yours since you have had it back? How many miles when you had the failure? Mine happened at 23100.

Mine happened at 39K.  Running great so far, I’ve had it back for a week.

Good to hear, thanks for the encouraging words!

I have the same issue with my 2019 GMC AT4 Sierra. Only 18,600 miles. The dealer suggested I contact GM and start a claim. How did this work for you?

In the long run, it worked out good, took a while.

 

Why are they suggesting you open a claim on a truck under warranty?

 

My claim was opened because the new engine was installed incorrectly in my 16, and ended up being a buy back from GM.

I told them I didn't feel safe or comfortable continuing on with the vehicle with such a serious issue at such low mileage. The service dept. agreed. I inquired about a trade or buy-back with the service department and that's what prompted the call to start the case. I have a case number now.....we'll see how it goes.

They do have a trade in allowance option, that is how my 14 went back and I ended up with my 16, which ended up being a buy back, and is how I ended up in my 18.

 

Time consuming, but in my opinion, my dealership and GM stepped up and took care of me both times.

How much labor does it take to replace push rod and lifters? According to GMC dealer here GM recalled all lifters on their shelves and issuing new part with different part number.

bent push rod in cylinder 3 in a 2021 6.2 GMC with 7100 miles, parts are hard to find. Finally off back order and on their way to the dealer. GMC says it's a permeant fix. Better not be a band aid fix.  Didn't get a loaner even though it's in writing. Said the faulty parts are all coming from one place. You'd think they would have this taken care of if it's happened in the past years....What a JOKE

I think to do a cylinder head R&R with lifters is something like 9 hours of labor. So take that and multiply it by whatever your shop labor rate is. Probably around the $1,300-1,400 if it's a higher labor rate plus all the parts you need.

      There's some truth to the above, but also, she's selling fullsize trucks and bread/butter CUV's like hotcakes, meanwhile, extracting GM's pickups from the deep discounting sales game.   GM's stock has held its own during her tenure, and the more recent buybacks are delivering cash back to investors and signal confidence in their direction forward. Even with the EV losses.   GM is an example of a modern publicly traded company. The #1 goal of any publicly traded company is to deliver the most value possible to shareholders. Despite being a car company, building the best car isn't GM's path to delivering maximum shareholder value.   McDonalds doesn't make the best burger, or the best coffee.   I've mentioned in another thread, I really don't / won't ever understand Cadillac or Buick in a modern context. Both brands are completely dead to me. I'll cede that the Escalade is a nice SUV, but the brand and nameplate mean nothing to me, and GM will never persuade me to pay north of $170k for a gussied-up Tahoe or Burb. Other people don't mind doing that and that's their purview.   The C8 shares absolutely nothing in common with any other current Chevrolet or Corvette on the market. Since its introduction 8 years ago, it's developed quite the following. It did what other Corvettes couldn't do: reduce the average age of its buyer. GM has something there, and I see them investing in the car. They'd better not mess that up.   We've successfully derailed Grumpy's thread again, but I think this one is meant to be more of a random thought thread so a little wandering is probably OK.

      Sliding doors ftw   Also, Sienna ftw as well.  The in-laws got a 2024-2025 recently when their 2019 sienna was totaled due to a deer back in June.  They've been getting 38-40mpg on the 65mph highway they live on.

      07 yukon xl 6.2 stalls at hot idle and wont restart

      By xdieselmechanic · Posted

      Forgot to mention that this started after changing the oil I use mobile 1 full syn with mobile one filter but I did add pro lube additive and was the first time doing so and is making me wonder just can't see why that would matter

      07 yukon xl 6.2 stalls at hot idle and wont restart

      By xdieselmechanic · Posted

      I apologize for long post put going to try to explain everything. Parts replaced so far: Cam sensor Crank sensor Cam phaser valve Cam phaser solenoid Fuel pump Maf 1 injector Pcm Pdm   So about 2 weeks ago coming off the highway my 2007 yukon xl with the 6.2 stalled and would restart. Had unit towed back to house and I messed around with relays and unit started. Drove it the next day and same thing. Had it towed again. Scanned unit and had code p0300 with misfire data showing mainly cylinder 7 but I know that won't cause a no start. Measure fuel pressure and found only 42 psi replaced pump to have unit stall again and not restart. This time I stayed on back roads and just waited for it to restart about 30 to 60 min. During this time I found I have no injector pulse but have good power at injectors. Started unplugging 1 injector at a time and found when unplugging cylinder 7 pulse came back so i changed injecto and same issue. Turns out unit just happen to ready to start at that time. Scanned into unit and found no reason for the pcm to take away injector pulse so I replaced the pcm and same issue. I figured timing sesnor controlled the injector pulse so I replaced both sensors and while I had the water pump of i replaced the vvt components while i was in there. Read multiple people have luck chaging the maf for this issue so I changed it. Unit still stalls to this day and loses injector pulse on the ground side when it does. Have noticed watching the live data the pcm is request injectors to fire via injector pwm value. I have redone the ground wires at the left bottom of the block knowing this was the ground location for the pcm but still no luck. I am a mechanic by trade but this is having me pull my hair out. If anyone has something to have me check I will gladly im not much of a parts thrower but im about to load the cannon

      auto mechanical driver's door unlock without pressing button? [2026 Silv. 1500 WT 4WD RC SB 2.7L]

      By newdude · Posted

      Actually.  Wait.   I just re-read your original post.  Are you talking from INSIDE the truck you have to hit unlock?  Or from the key fob?  I had assumed from the key fob.   IF you are talking the inside unlock button, I assume you are shifting to park and its not unlocking the doors?  If so, that is changed via the settings page in the radio.  Go to SETTINGS, then VEHICLE and then it should be under LOCKS or DOOR LOCKS or something like that.
