The engine has a hesitation due to a manufacuring problem it also uses more oil than it should between oil changes. Also having problem with the electrical system every time I turn around something stops working like the side mirror on the drivers side won't fold in like its supposed to and the backup sensor stopped working. Tried to get our mechanic to fix it but it needs a code to get into the electrical system and GM won't give it to anyone but thier own mechanics. So now we have to go to the dealership to have it fix which will cost alot more. About amonth after purchase the dash got a small crack around the passenger air bag. This is our second 2007 Avalanche the first one had no problems at all and I had no idea that this model had so many problems that the manufacturer won't fix. With as much as these trucks cost even used the should have to repair things that are manufacturer defects

Total engine loss at highway speed, Chevrolet want to replace the engine, but as I read all these complaint about engine and oil and afm. I believe they should be held accountable for selling lemons. The NHTSA must put a end to manufacturers selling trash.

My main concern is the fact that the vehicle burns excessive amounts of oil. I have lodged about five complaints with ourisman rockmont Chevrolet and my concerns remained unadressed. They did, on one occasion, change a gasket cover and oil pan gasket, but the problem persisted. Finally, I was recently told that I needed an oil deflector per a service bulletin and was told it would cost nearly $1,500. Although my concerns were all made during the warranty period, ourisman is attempting to charge me now that my vehicle is outside the warranty. I contacted Chevy customer service but no luck.

This vehicle has had oil consumption problems since purchased. It runs out of oil 1500 miles after an oil change. Several consumer complaints have proved this is a very common problem and suggested reporting it to the epa. My truck now needs a new engine because of this common defect with the afm and bad lifters in the 2007 Chevrolet Avalanche. It is completely abnormal for an engine to burn this much oil into the environment. Not to mention the consumers who are now being forced to replace engines due to this problem. It needs to be fixed.

Date of current incidents: 1/3/11; 1/4/11; 7/28/11; 8/23/11; 9/07/11; 12/9/11; 12/16/11; 6/4/12; 6/10/12 and 6/11/12 and 6/L7/12. The engine light comes on; engine reduce power light, stabilizer tract light comes on plus oil light and other lights. I have had it in the shop to try to figure out why my Avalanche keeps breaking down. And I was told that they can not find a problem. I was never informed that they have had probems with the wiring. In December 2011 my Avalanche shut itself off during a snow storm. Eventually, it started but because of reduced power it would only go between 35-45 miles per hour. I made it to a repair shop, they could not find a problem, but replaced sensors and/or relays. In June 2012 the lights came on, I could only go approx 35-40 miles per hour. Called and set up an appointment. On the way to the appointment the engine oil light came on and the car shut down. I had to call for a tow truck. I took it to a non dealer service repair shop, because they were the closest. When they looked the car over the wires were eaten. I was informed that the newer cars have a soy base in their wiring and that the rodents love to eat this product. Why are they using this soy based wiring? this is not safe. I can not have my vehicle break down leaving me stranded on the side of the road. It is getting very costly when parts are being replaced when it is the wiring that is faulty. I live in the country and I can not keep the mice out of my truck. Please look into why the car manufactures are using this product which is causing major safety and financial concerns why aren't the manufactures informing the public of this problem.
