Sorry to hear! I have a 2021 6.2 and the driver's side lifters needed replaced at just under 12,000 miles. I was pissed that they wouldn't just replace the passenger side also while they were in there. But I'm at 45,000 miles now and still no issues from that other side. Sounds like they only did one side one yours the first time tooFirst at around 4000 miles and now at 18700.....2020 trail.boss 5.3...booooolshit is what it is...even the service writer said to.trade it off before the warranty is up....
All I will say it has a twin screw bolted to it for gas mileage purposes only. After the 6/60 elapses I'll pull it if it doesn't fail for some reason. Just want to drive it and if it fails I will have it covered under warranty and save it for a spare. All I'm waiting for.If he has an engine in waiting I’m betting it’s something better than a 5.3.
Thanks for the info....the service writer said he'd trade it off before the warranty expires...i wonder if the 2023 still have this lifter problem?Dave,
Here is a phone number for GM national customer service 1 (800) 222-1020
Call them and file a claim. Tell them you demand BOTH sides of your lifters need to be replaced. They do answer that number and will talk to you.
When my lifter went I had to fight with the dealer and Chevy National. It was ugly and a lot of BS but they finally agreed to replace both sides. Their policy is to judge everything based on the cam shaft. If it is not damaged they only do one side. That means the guys that try to keep driving it after the failure get a proper repair. Put up a fight to get those bad parts out of there. The squeaky wheel gets the grease!
Would you do a LS swap? That is my plan. I don’t know much about the 2.7 but it knocks and pings constantly. It only has 5000km on it. I’m wondering if I should do a oil change soon
