2007 Chevrolet Avalanche: check engine light

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

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.

Two weeks ago driving 60mph on highway in snow engine light illuminates and lose total power. "reduce power mode" illuminated but engine shut off. We almost got rear ended by a tractor trailer on [xxx]. On side of road for 2 hrs in 20 degree weather waiting on aaa (no shoulder on hway) and motor starts. Take it to garage and get throttle position sensor (tps) code ans stabilitrak/ABS code. We had accidentally hit the onstar button a minute before this and mechanic thought that was related so he cleared code and sent us on our way. For two weeks we were good andit happened again on highway in rain [xxx] this weekend, again in middle of highway. This time car started after five minutes. Took car to dealer and they state the tps needs replacing and front wheel speed sensor broken. There is a gm service bulletin #11273b where gm acknowledges tps issue and covers replacement of tps for 2008-2011 vehicles. Also bulletin pip3089b for bad wiring to tps for 2003-2006 avalanches. Gm denied my service despite the fact that a 2007 tps and throttle body are the same exact part number as the defective one. This is super dangerous and extremely frequent as there are 550 posts alone on [xxx] as well as many reports to [xxx] please assist as they are not standing behind a defective and deadly product as the computer cuts total power right on highway...

Entered interstate 74 in indiana,got up to 65 MPH and traction control light came on along with the check engine light. Had 30 miles to go to get to destination so kept driving and lights would go off after about 3 minute interval and would come back on. This happened about 8 times during the trip. Finally the lights went off and did not come back on as of yet. My wife and I heard a clunking noise during this period of time. Very concerned that this may happen again when my wife is going to grocery store or any where by herself and get stranded somewhere. She is afraid to drive the 2007 chevrolet avalanche now.

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.

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. Unfortunately their dealerships and district specialist do not follow their own executive director of safety who is quoted on the gm website "we always want to make sure customers can count on the safety and quality of their gm vehicle." says, [xxx].
