After a weekend of camping (rv) my Avalanche would not start, battery less than one year old. The RPM $ mph were moving up & down, clicking sounds were coming from the front seat arm rests, no power to the windows & locks. Vehicle was parked & both the Avalanche & rv had to be towed. Diagnose-U0140 loss of communication of BCM, defective body control module, replaced control module.

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

I used my factory remote to unlock the truck the ignition sparked twice and then went on fire, for no reason it just started burning the entire steering column and all of what is around it burned up we used a pitcher of water to put the fire out, I contacted GM and was advised there was no recall for this. It can not be common for a car or truck to just ignite unlocking the doors we are grateful that I was not in the truck and just suffered burns to my hands trying to put the fire out if not my entire home would have been in flames.

The alarm sound for warning of seat belt unbuckled, door open, keys in ignition, etc, is generally inaudible. Occasionally it does work, but usually it does not. In 2010, the dealer said this was an issue with the radio. My warranty had expired so repair was no longer covered. I did not have the problem repaired due to the high cost. I thought that this was an isolated incident until I just read that there is a recall for this exact problem in later models. - when functional, the alarm sound emanates only from the speaker on the left side. I swapped the left and right speakers and the problem remained, suggesting that it is not a speaker issue. When the audible alarms are dead, so is the left side sound when the radio is on.

2007 Chevy Avalanche I believe should be included in this recall #1: 2004-2012 Chevrolet Malibu, 2004-2007 Chevrolet Malibu maxx, 2005-2010 Pontiac G6, 2007-2010 Saturn aura. The vehicle, when scanned is producing an error code of P0573- cruise control/brake switch a circuit. As a result of this error the functionality of my cruise control is jeopardized, rendering the vehicles cruise control at sometimes useless, not functional or worse disengaging without warrant causing a safety concern while driving.

I called emergency services, but the vehicle was totally engulfed in flames before they could put the fire out. The vehicle was was a total loss.

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.

Avalanche 8-cyl

  • 77,912 miles
Traveling at a normal rate and speed on a 5-lane highway. Vehicle loss power, engine lights activated. After maneuvering the vehicle off the highway, I shut the engine off. No signs of smoke or any leaks from engine (topside or underneath). I attempted to restart the vehicle and upon doing so the engine turned over and ran at a rough idle, clearly not on all 8 cylinders. I shut the engine off again. From that point on it was towed. The Chevrolet dealership (after 8 days and 449 miles later) then told me they could not find a problem. When they received the vehicle the original codes had been taken by a precision tune mechanic (nearest facility from location of break down) the dealership then informed me they could not duplicate the problem and was apologetic for any inconvenience. I received a bill for $103.95 and my vehicle which had only a 1/8 of a tank of fuel. After a little research I found GM recall no:08048 consequence: May cause electrical features to malfunction. Thanks Chevrolet and Chevrolet service technicians for taking care of your customers.

In Apr 2009 I took my 2007 Chevy Avalanche in for servicing. The "check engine" light was on and I had recall #0848 performed. This recall was to install a wire harness (heated washer fluid module shortcircuit). The catalytic converter and an 02 sensor was replaced. Approximately Aug/Sept I had an odor in the vehicle (smelled like dirty feet or the interior carpet was wet for some time, without proper ventilation to dry. However, I thought that was odd as I was unable to locate any leaks inside the cab of the vehicle.) on or about Oct 2nd, I was driving on the freeway and the "check engine" light came on and a message to turn off the engine which I did. After being towed to the dealership, I was told the engine had lost oil pressure and a sensor was replaced. Immediately after the work was performed the smell went away but that same evening I was driving and the windshield wipers started going, fluid spraying, while in the off position. I had to turn the vehicle off to get it to stop. I immediately notified the dealer, since this has happened 2 or 3 times. The end of Dec I took my vehicle in to the dealership for the intermittent wiper/fluid problem and I thought the transmission was slipping. They couldn't find an issue with the transmission and their diagnosis for the wiper unit was that the module was bad and needed to be replaced. They referred to bulletin #4298, dated 02/26/07, and part #1910885. It is my belief that all the failed sensors/parts are related to the recall and I am hoping the investigation to the recall is still open/on-going. Fyi: Within the first year of purchasing the vehicle my battery needed to be replaced after being inspected at the dealership. If I remember correctly there were several occasions I was unable to start the vehicle. There should be records on file at the dealership pertaining to this issue. Lastly, I do have the part that was replaced as a result of the oil pressure sensor.

Have a 2007 Avalanche ltz with everything in it. Had the same problem letting it set for extended period of time and having battery dead when going to start same. Jumped it and started fine. I can hear the computer working when vehicle is shut off and believe this is why. Need to start same often and run or put a battery charger on same solar to keep from happening. Dealers say they can find no reason for it.

Truck failed to start due to dead battery after sitting for less than 24 hrs. Since purchase 5/07 it has occurred 6 times--7 if you count the day of purchase. Truck is dead again today and is at the dealership (12/6/08). This vehicle starts immediately after being jumped. They can never find anything wrong, and no stored codes whether I jump it then take it in or tow it in. They suggested that I was leaving accessory items plugged in-of which I was not. All recalls have been addressed. Dealer/GM will not admit a problem exists and replace the vehicle without a huge financial debt to me. Vehicle was purchased new, one owner and currently has 19000. Original complaint after purchase was 10/07 and 6475 miles.
