#23 of 71 Engine Shuts Off
Aug 14, 2009 (8:33 am)
I have the same problem its been happening for awhile with me i found out that its the ECM fuse it keeps blowing.But with mine my truck doesnt start unless i replace the fuse. From what i been told is that the fuel pump might be going but also been told that it might be the distributor going as well. it actually just shut off me on yesterday but for now i jus keep extra fuses in my truck with me for the time being.

My truck has been running "rough", loss of power, sputtering. Check engine light is on intermitten. I had Auto Zone read the code and it was a mass airflow sensor. I bought a new sensor and it seemed fine, the engine light went out. Today (one day later) my truck wont start. I thought I may have gotten a bad sensor so I got another one. I will try it tomorrow. Just wondering if anyone else has experienced this problem. Thanks!

I'm looking for a new car/truck/SUV and here is my dilemma: I like Avalanche’s look, but Tundra’s reliability. Currently I have 1999 Ford F-150, and never had any problems with it. I bought it brand new and now it has 140K miles on it. Once a while I need a pick-up truck, and I’d like to enjoy the nice look of it. The bed in a new F-150’s appears much bigger to what I’m used to and I don’t like it. I like the appearance of Chevy Avalanche, but I’ve read that people are having some problems with it. On the other hand Tundra would be more reliable, but it is rather a typical pick-up truck. I might also add that my teenage sons dream of Avalanche. Can you advise me please which car to choose from, or give me some thoughts to start with?

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.
#29 of 71 Lifter noies
Mar 08, 2010 (7:59 pm)
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.

#32 of 71 avalanche quit running and now wont start
Mar 03, 2011 (5:30 pm)
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!!!
