2010 Chevrolet Avalanche: check engine light

Filed May 17, 2021 · MO

Having alot of issues with the drain tubes especially with the front top tubes my floor boards are being soaked. The tubes are plastic so when and why for the drain tubes and how often should they be really be changed. The seal above driver door and passenger door in front are not always put in correctly or they move causing the water to cross over and pull into car instead of exiting. And the ac plug also problem. Certain years do not have the cabin filters .The engine light is very sensitive as well.

Asking if anyone knows about the 2010 chevy avalanche and the ECM problems that alot of people are having , the check engine light came on and the display showed reduced engine power, service traction control, and service stabilitrak. It would not go in gear , nor would it start , this had happened to the truck three times now , the first time it would not go into gear and it stopped and would not start at all , so I took the negative battery cable off for 30 minute and it fixed it . The second time all the light and buzzers went off , I had lack of power and the check engine light came on and the display showed reduced engine power, service traction control, and service stabilitrak while I was driving it so I took it home , I was lucky that I didn't get in a wreck because it dropped drastically in speed all at once , again I took of the cable , and went to have the diagnostic reading done at a parts store , the next day I drove it to my mechanic and he cleared all the history on it and told me to call when it happens again , it seems that the 2010 avalanche has this problem alot , so today it happened again , for no reason ,

Stabilitrac and traction control lights came on along with service both and the check engine light is on and sometimes flashes. Truck is idling very rough and seems to downshift hard from 2nd to 1st.

The dashboard has cracked in 2 locations. The 1st runs into the corner of the passenger airbag compartment. The 2nd is over the instrument cluster and now I have a check engine light on. Not sure yet of the 2 are related. The first crack just seemed to appear. The 2nd crack (which is much worse now) I could hear it crack when I started the engine sitting still.

Immediately upon starting my truck, while in park, the dashboard indicated the vehicle was in reduced engine power mode and the check engine light came on and the stabilitrak was disabled. The truck would not accelerate properly and would only drive approximately 25 MPH. This is the 5th time this has occurred on this vehicle. The dealership informed me that it is the accelerator pedal positioning sensor, which is the same issue it has had each of the previous 4 times time. It happened 7 times on my 2007 tahoe and each time it was the accelerator pedal positioning sensor (which is the reason we sold it). We are thankful that this time it occurred with the vehicle in park, this has happened in this truck on the highway and that was very dangerous!!

I was on vacation and had my avalanche running while I packed it up to return home. After about 5 minutes of running idle, the check engine light came on and the display showed reduced engine power, service traction control, and service stabilitrak. This had happened to the truck three times before and each time they replaced the accelerator pedal positional sensor. (I also had a 2007 chevrolet tahoe, and after having it repaired seven times for failing sensors and going into reduced engine power while on the highway three times we were forced to sell it). We are very familiar with this issue! However, I was able to locate a dealership in the area and they tested it to find that the throttle body was out, and they replaced the throttle body and the associated sensor. I was relieved to hear that this was a different issue than before and that my problems were fixed. This was not the case. Last week, the engine power reduced again and the truck is now in the shop for the fifth time.

I was driving on a bridge when the check engine light came on and the engine power reduced. The truck immediately dropped to below 30 MPH and I could not accelerate up the bridge and barely avoiding an accident, as this was in a heavy traffic area. I was able to get it to the dealership and are working on it now. This if the fifth time this has happened to my truck. My wife and I just sold our 2007 chevrolet tahoe and the only reason was the engine power reduced error occurred on it seven times, three in month prior to selling it. This is a major problem and could have easily resulted in a severe accident. Both cars were only ever serviced at chevrolet dealerships and each time, they insisted it was fixed and the problem was gone. We have no faith in chevrolet at this time!
