Chevrolet Avalanche Engine problems by year

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 am an owner of a 2013 Chevy Avalanche and must say that i enjoy driving this vehicle. The problem that i have is the vehicle has been going into Engine Power Reduced Mode. This mode makes the vehicle hard to accelerate to highway speeds. The vehicle will have a code of P2128 or P2138 which is an accelator pedel ciruit problem. I changed the acceleator pedal and did not solve the problem. I changed out the Throttle Body Sensor and still the problem remains. On the dashboard it will show Check Engine Light on,...

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.

My chevy avalanche has a generation for vortex 5300 engine we are using at least a quarter volt in between oil changes also the oil monitoring system is allowing me to drive and to operate the vehicle without adequate oil because the oil gauge is not reading when the oil is ready to be changed. This has been happening since the day we purchased it new in 2013 we were told by the dealership that this is typical of this engine I'm now finding out that it is not and that it is involved in a class action lawsuit and I need to be documented in that lawsuit.

I have a 2008 chevy avalanche ltz with the 5.3L v8 engine with adaptive fuel managment. It was purchased used with 120k miles. It became apparent that the engine was consuming oil, 1-2 quarts per 3000 miles. Recently the engine started producing white/blue smoke on start up and oil consumption increased to 2-3 quarts in 1500 miles. My vehicle is currently at a mechanics shop and I am told that for starters I will need new valve covers that are redesigned from the original ones and that excessive oil consumption is...

Purchased a used 2011 chevy avalanche with 87,000 miles one owner from a small dealership. After having the vehicle for about a week noticed it shuddering when pulling any kind of grade. Thinking it was some kind of misfire had all the plugs changed only to find that it also had an oil file problem with 1 of the cylinders. When the vehicle would shudder it was around 1500-2000 rpms. If I would give it more gas it made it past the 2,000 rpms and would shift with no problems. Needless to say the transmission is now...

Stress fracture in front dash pad around air bag cover... Extremely noise lifters on startup ! *Tr

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. *Tr
