Service stabilitrac system indication comes on, with check engine light, and engine power reduced. Happens randomly, cannot find a "common cause" spent lots of money on PCM, bcm, memory seat module, battery cables, battery, brake light switch, etc. Etc. Dangerous condition when vehicle drops into power reduction mode.

The airbag indicator light is on and off. Took it to serive centers the light came off for a week then came back again. Mechanic told me the spring coul needs to be replaced got it replaced but the problem is still the same. When ithe weather is cold the lights comes off when its warm the lights are one told the mechanics they said its the connection they tried to fix light will come of for a few days then back again. The second problem is the engine light - they told me its the fuel ejection pump got it replaced but not resolved. I keep taking tthe truck back to the service centers but after a week the light indicators are on. I also failed my inspections due to this problem. The only reason I pass is that it has to be fixed but after inspection the lights are on again. I have read all complaints about this problems but gmc motors doesn't have an active recall for it its just a communication stating the problem. The truck is still running but this safety issue needs to be resolved by the company. And I think thats part of the reason tgey dont make the avalance anymore.

At 80k I put my truck in reverse and heard a clunk sound and immediately it wouldn't shift gears anymore. I went and had the transmission rebuilt which lasted roughly 10k more. Now, the truck won't shift yet again and the filter was changed and the rear output seal. Currently, when I drive since its my only vehicle, one minute it will shift fine but after I turn the engine off and on again, it will not shift from first and the again, check engine light is on!
