Keep us posted, gtrottier109. I am guessing that you're outside of the United States as you're using kilometers as your unit of measure. If you need information for how to contact Customer Service in your region, let me know your country and I will get that to you.

I can tell you this, depending on your onstar does not save you, they want to see that you are using a GM approved oil filter, as well as oil. and that the oil changes were done at the correct times. I have also learned from the service techs and other GM personel that they are having engine issues with their onboard oil change indicators, I am told that I should not wait till my indicator say 10% or less but to change my oil every 5000 - 6000 km. After my first engine problems started they opened up the engine, the Cam was worn, lifters collapsed and they said there was so much sludge in the oil pan. I said i had always serviced my vehicle at the GM dealer regularly. They said they knew that and it is a problem . They will fix your engine for now, but it will not fix the problem. Mine needed a new engine, after basically being rebuilt. 10,000 miles later they wouldnt repair it anymore. ( just after warranty ran out )
 
Good luck !

Hi there Wheel61.
 
Your experience comes in handy in this case. While I understand your points, I am hoping that they will cover it even if I cannot produce all the receipts. After all, the truck was brand new when I bought it (56K sticker price) and has only 26K miles over 3.5 years... warranty is 5 years/100k miles on the powertrain. If I had been at the 70-80 K mark with it and could not reproduce all receipts, I would understand. but at 26K, I shouldn't have to when it is tracked. You are right that OnStar doesn't prove anything though but at 56K $, I am not someone who will cheap out on an oil change. I thought this truck would last me at least 10 years... guess I was wrong.

Hi there Wheel61.
 
This is what's happening now. My engine is in pieces at the dealership. I went at the garage and asked to see the engine on the table... Sure enough, cam shaft has a gouge in it, lifter is scratched. the service tech told me they will change the camshaft, and all lifters. He also mentioned they come in a kit, this is why they change them all. Might as well, engine is in pieces...
 
plugs seemed fine. No oil accumulation whatsoever on them
 
I was surprised, but they rented me a car. They had no loaner on the lot, so GM pays for the rental. Everything under warranty. Can't ask for more I guess. They rented me a Cruze... pretty good little car. I want my wife to try it but after the engine problem on my Av, she says no Chevy for her...
 
Should have it back tomorrow or Friday and will let you guys know how it feels after.

Got my truck back on Friday.
 
Engine running smoothly, seems more powerful a bit, but it might just the fact that I was in a Cruze all week....
 
Had the dealer show me the invoice... 3200+ $$$
 
Powertrain warranty covered it all... cannot be more pleased with the service I had at the dealer. Surprisingly enough, I had not bought the truck at that dealership, so I thought it could be a problem, but not at all.
 
Hopefully, the fix will last for good.

#59 of 64 2012 AVALANCHE ENGINE TAP by bopper425

Mar 19, 2013 (4:52 pm)

JUST BOUGHT THIS TRUCK WITH JUST 2,500 MILES ON IT. NOW I KNOW WHY. WITHIN FIVE DAYS OF BUYING IT, IT WAS IN SHOP FOR 4 DAYS GETTING LIFTERS REPLACED BECAUSE I HEARD ENGINE TAPPING. GM DEALER SAYS THERE IS A BULLENTIN OUT ABOUT THIS ISSUE. SO I GOT TRUCK BACK AND ITS STILL MAKING TAPPING NOISE.DEALER SAYS ITS "NORMAL". YEAH RIGHT. SO I TOOK IT TO THREE OTHER CHEVY DEALERS AND GUESS WHAT,THEY ARE ALL SAYING ITS NORMAL. I HAVE BEEN AROUND ALOT OF VEHICLES IN MY LIFE TO KNOW THAT THIS IS NOT NORMAL. I THINK THAT ANYONE WHO WORKS FOR GM KNOWS HOW BIG OF AN ISSUE THIS IS WITH THE 5.3 ENGINES THAT THEY ARE ALL HUSH HUSH ABOUT IT. SO NOW AM STUCK WITH A 40000 DOLLAR PIECE OF CRAP. CHEVYS IS ALL THAT I HAVE BOUGHT IN MY LIFE.THIS WILL BE MY LAST.

Send me an email to coveyjsgmail.com; there are a couple of things that happened to mine. First off, check for something lose in the bumper. This may sound odd, but with all the weight of the cladding if there's something lose it's going to make a squeaking noise that will seem to change with the pitch of the engine due to vibration. Easy way to test is to park it, open the hood, stand on a chair, lean on the front upper cross member and push it hard repeatedly. If you hear the squeak, then it's in the bumper assembly.
 
The second issue is a lot worse. I was told that Chevy had a major problem with soft cams. The noises started 150-160,000 and by 200,000 it was throwing error codes for misfires. The solution there was to replace the engine with one that had 80,000 on it. Expensive, but much cheaper than a new Avalanche.
