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.

- Prudenville, MI, USA

Stabilty light came on, loss of power, check engine light, rough shifting into 2 gear. It has been down for 2 years. And not fixed yet, Chevy dealership does not know what tpo do. There needs tobe a recall on the flex fuel. We were going down I-20 when all this happened. There was nearly an accident

We were driving down I20 when we were coming off the off ramp and the stabilization light came on and we got to the stop sign to turn right and as were take off it shifted really bad out into 2nd it jerked really bad and we had no power we made it home and now it turns over but will not start. 2007 avalance it has 50,000 miles. I have been talking to other people on car gurus and there are thousand on that sight having the same problem were having. And the sad thing is we dont have the money to have our truck towed into town and get it fixed. Becasue they tells us that they have so many people having the same problem. I feel like GM should do a recall or people should be able to do a group lawsuit toward GM for such a big deal like this is. And also our dashes are all cracked down the middle. Which on that sight there are alot having same issue.

- Odessa, TX, USA

Stability control warning pops up on display, resulting in a severe power reduction. This causes the vehicle speed to drop from 70 mph to around 35mph instantly. This nearly resulted in a rear end collision, of course. This was only prevented by a very alert driver behind me. I read that this is a very common issue with GM vehicles yet nothing is being done by GM to provide a safety recall

The manufacturer was contacted to determine if the remedy and part were available for NHTSA campaign number: 16V383000 (air bags). The approximate failure mileage was 140,000.

The 5.3 engine has had many complaints from owners where the engine fails due to oil recirculation and valves going bad. The manufacturer will not do anything to replace the engines. The engine starts running extremely rough and had to be towed to a repair facility

- Houston, TX, USA

The vehicle, from the time it was new, had usually consumed about 0.5 quarts of oil each oil change, which I would consider normal. This condition began to worsen at approximately 60,000 miles to about 1.0 quarts per oil change. This condition continued to worsen, and at approximately 85,000 miles began to consume 1 quart of oil each 1,500 miles in city driving, and closer to 1,000 miles with significant highway driving. I contacted the dealership regarding this issue, and they replied that this amount of oil consumption would be considered normal. Between 85,000 and 135,000 miles I have replaced spark plugs twice. In each instance the plugs were fouled and wet with oil. The ignition coils were replaced on multiple cylinders at the time of the first spark plug change. As compared to the owners manual, the spark plugs should only require service every 100,000 miles. I have since contacted the dealership regarding this issue, and they continue to reply that the amount of oil consumption I experience is normal. I have owned more than 10 vehicles over the course of +30 years and never had an engine consume oil at this rate. This amount of use is neither normal nor good for the environment.

- West Seneca, NY, USA

Vehicle used way too much oil. Oil consumption was extreme. Began to hear a ticking sound, while driving on expressway the lite up like a christmas tree. And smoke began to billow out the exhaust. Took it to dealer said I needed a new engine. Reading posts on line everyone is complaining of same issue. This should be remedied by manufacturer. Now car is sitting waiting to get an engine

- Browns Mills, NJ, USA

It started with a ticking noise and when I took it for service they said that it was my lifters and to replace them it would cost 5-6 thousand, and that I might as well replace the engine. I later find out that this is common with all the 07 but the manufactory want recall or assist with replacement cost.

- Livingston, TX, USA

There have been continual problems with the engine of my truck and I have found out since buying it there are severe problems with a lot of the engines of the 2007 Avalanche. The mechanic told me when we brought the truck in to find out why the engine had a hesitation in it, that we should hope it was the exhaust system seals needing to be replaced that caused the hesitation because the only other times he had seen this problem it was a manufacturing defect in the 2007 GMC engines that he had seen these problems with alot of the 2007 Chevy and GMC trucks including his own. We also about 2 months after buying the truck noticed that the truck was going through oil very quickly but the mechanic said that the seals weren't leaking so didn't know why we were burning oil so fast. The dash has cracked at the corner of the air bag and if there is an accident it could send shards flying. The drivers door sticks and the stability control go's in and out of working order. The electric mirrors stopped folding in and tilting down and tried to have it fixed but Chevrolet said they wouldn't give the mechanic the code to get into the computer system to fix it and the back up sensor that had stopped working also. We now have to go to a Chevrolet dealership to have it fixed. There have been so many problems with these trucks that Chevrolet hasn't fixed these trucks even used usually cost at least $15000 brand new you could double or triple that price I don't think it's a lot to ask to have a decent engine the other problems I could deal with but the engine problem they should fix
