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.

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.

My dad bought a 2003 Avalanche that had 111,749. It has been in the shop for the cluster and other things. The vehicle has about 115000km and has no oil pressure. The dealership indicates that it is a rod bearing and the engine needs to be replaced. I understand that the oil was changed at the dealership when it was bought (july 2012). The oil was also changed by the dealership in december to a semi synthetic. So what gives.
