2014 GMC Sierra 1500: check engine light

Filed Feb 18, 2026 · Engine · WA

The vehicle experienced complete lifter failure on cylinder number 4 bending the intake valve push rod thus shutting down the cylinder. The vehicle has 167,000 miles and is well maintained. The vehicle gave no warning signs that there was a problem. Simply driving down the road, normal engine temperature, normal oil pressure, the check engine light comes on at the same time the engine begins to mis-fire. Pulling over to the side of the road, I could hear lifter noise from the right bank of the engine. The dealership (Ocean Crest Chevrolet/GMC Warrenton, Oregon) confirmed the damage. The mechanic and the service manager both state the damage is a direct result of the GM cylinder deactivation system, and every single one they have repaired has been cylinder number 4. They further stated that GM has recommended a lifter change when repairing the damage, in other words, the lifters that were installed when the engine was originally built are defective. This damage occurs on both the 5.3 and the 6.2 with cylinder deactivation, and according to the dealership, it begins with cylinder number 4. This problem has also been responsible for cam damage which results in total engine replacement/rebuild due to metal contaminating the oil.

My truck recently had an engine lifter fail when pulling out onto a very busy road. When I accelerated hard into traffic my check engine came on and I suddenly lost most of the engine power and it went into limp mode. I was almost rear ended when my truck nearly came to a stop. I was told it is a defective/poor design of the cylinder deactivation system from the dealer. Ther is no fix but to replace with the same lifter part number which was done and it also failed again 4 days later in a similar situation turning onto a road into traffic. My truck is now back in the shop to have lifters replaced twice in one weeks time.

From time to time the vehicles power system will surge, blink, and generally act up. The priblem is intermittent. The check engine light will come in then go off, the engine has completely cut off several times while driving, the transmission acts up, radio will turn off, 120v outlet will turn off, occasionally the vehicle will fun for 5-15 seconds after being turned off and then sputter off. And 95% of the time the truck is absolutely fine.

Should this be a recall situation?

I took my truck in to the local gmc dealership for the recall fix and they ask if I wanted a diagnosis on the truck for a charge . I said yes cause I had a check engine light on and service air bag light on. Which they both came on a week after I bought it. So the service advisor told me that the belt tensioner is out on the drivers side and that the wiring under the drivers seat is messed up. And they told me some other things that were wrong with my truck that I have since found out were false. But I asked him if the seat belt and working issue is covered under a safety warranty. And he said no and to fix your truck it will be 5400 dollars. I have found out that there is a recall on these items and the recall number is 15522. So I would like to find out if I'm or the services advisor. Thanks
