I have an 2003 Avalanche and replaced the motor at 53,000 miles. Talk about sick. Screw GM and American made if all I get is a POS that I had to pay over $7,000 to repair. It had been a good driving vehicle but I don't think I will buy another. Currently, the electronic display is stuck on whether I should select english, french, or espanol. In the name of technology I can't see how many miles I have without dropping more serious cash. I think I need to stop before I get on a ranting ti-raid.

I purchased a used 2007 Avalanche from a non GM dealer with about 29,000 miles at purchase it now has 35,000 miles 1,000 hours on it. The dealer I purchased from serviced the vehicle with oil change. Time for my first oil change the lifters started to make loud noise similar to a diesel at idle and check engine light came on then started to misfire on number six cylinder. I drove it to dealer for service and oil change and dealer stated error codes P0521 and P0300. During the oil change the dealer stated that engine sludge was the problem. Recommended pulling the oil pan replacing the oil pump all not covered by the warranty “due to lack of maintenance” and possible replaces lifters or total engine replacement. I gave the OK to pulling the oil pan and replacing the oil pump but wanted to see the pan before cleaning. I looked in the oil pan no sludge present pan was clean but some carbon flakes less than one fourth the size of coffee grounds in the sump. I also noticed some larger flakes in the oil pickup screen. I told the dealer to flush the engine two times and change the oil then try to see what happens. Lifters are a little quitter now but check engine light is on and still misfires on one cylinder. Any help would be appreciated.

My 2003 Avalache was idling in a parking lot and quit running which it never has before. Trying to restart it, it will turn over but not start. The check engine diagram is now on in the instrument panel which also has never done before?? Any suggestions?? I checked the fuses and disconnected the battery, still didnt work? After continuous attempts you can also smell gas so I am assuming its not a fuel issue. Help please!!!

I have a 2002 Avalanche with 150k miles on it and have had only one mechanical problem with it and that is the front wheel bearing went bad. I love my truck and probably will never buy anything else. In fact due to the snow and ice I let my wife use it several times this winter and now she wants one so we are doing some shopping. Definitely would recommend the Avalanche.

My 02 did the same thing right after an oil change, I went to Wal-Mart and bought a $2.50 bottle of STP oil treatment and it runs like a champ again.

I realize this is an older post but thought I would let you in on a current experience that I am having with my 09 Avalanche...I love the truck but have had the oil pump changed at 75K miles via the dealer warranty and had the same chirping sound...turned out to be the cam shaft and lifters...again replacedat 98K miles by the dealer warranty. I have owned the truck since 8-5-09 when I purchased the truck with 5 miles on it...I have driven over 93,000 miles in the 2.5 years that I have owned the truck..lots of highway miles...I have used Royal Purple 5W-30 oil as recommended every 7K miles... I just pray nothing else goes wrong....its still not paid for but the service warranty is about to expire...
I have always driven a GM product...I own 5 other Chevy trucks with 5.7 litre motors but have never had these types of engine problems. I love the gas mileage...my AV is a 4x4 and has never left the highway...and I get 21.5 on the highway and 18-19 in the town driving...If the engine proves reliable I would like to own another Av as my dealer states that GM will discontinue it in 2013.
