2007 Chevrolet Avalanche engine problems

Filed Apr 21, 2026 · Engine · MS

Traveling hiway on cruise. My 5.3l down shifted to accelerate to go up an incline. Shortly after that there was low to almost no power. Check engine light then came on. I was able to do 30mph on freeway to get it home. Took it to a local garage since gray Daniels chevy wouldn’t service it since I recently transitioned to MS. The problem was the #4 lifter had collapsed. It costed me just shy of $4k out of pocket. I’ve read that this was a recall item for my vehicle, I was never notified. I would like to be compensated if this was indeed a recall item

I drove to work & parked my 2007 avalanche in my employers truck garage as I do every day. I went into the office attended a job briefing & we put on our coveralls for work then we got ready to leave to go to the 1st jobsite but as soon as the 1st two coworkers walked out of the shop they turned around yelling that my truck was on fire. I didn't believe them at 1st because I had just parked like 15 minutes prior. Parked & not running. Well I looked and my whole engine compartment was full of flames. We used 4 fire extinguishers to put the fire out & the fire department arrived to finish. My vehicle was totalled & I only had liability insurance.

Vehicle has 120,000 miles on it and has a random misfire, with traction control and stabiltrack warnings and a flashing check engine light. Engine has excessive oil consumption and runs rough. Installed new plugs and wires, no change. After reading up on these engines I found out that the afm / dod feature is a common failure for these engines. Gm should step up and help owners with some of the repair costs. This is going to be expensive.
