One month at dealership, they said its ready. I asked what was the issue? They don't know!!!!! Really!!! Wtf? They claim they drove it a month and it didn't act up or show any codes. WHAT???? I got a bad feeling they disabled traction control and sent me on my way. Is it time to hire a lawyer??

You need to make sure your review what the repair order says and ask to read the technicians notes. These rigs have a special coverage (extension of the factory warranty) on the throttle position sensor. There is an updated design to respond to these reduce power issues. Usually related to code P2135.

Had this issue with a 2010 Avalanche. Engine raced while idling and two indicator lights came on. Dealer was excellent, replaced throttle body and serviced it. Nice job.

Hi all im having the same problem on my 2012 silverado..my question is how much does this fix cost at a dealership (estimate)

Just started having this stabilitrak warning reduced power issue. Only 45000 miles and this is the second engine meltdown already.
The last one was at least subject to a recall.
Now I get to go to the dealer and hope GM will fix another one of their problems.
Gonna be hard to justify another Chevy purchase, especially if this is a hassle.

This same problem happened to me before and it went away by itself.I drive a 2008 Chevy Tahoe LTZ Flex fuel with 76000 miles. Now the other day it came back and hasn't gone away. Started to look into it in this forum and other GM forums and the same problem is happening to a lot of people. The dealer says it's not cover under warranty but I have read that some dealers are covering it. How can I figure witch dealers are those fixing this problem. Has GM done anything about this? Please help.

After getting the service stabilitrak, service traction control engine light and rough idle I thought my tps was bad.
So, took it to the dealer who said oil was built up on plugs and in cylinders, etc and accused me of not changing the oil.
Luckily, a mechanic friend sent me a couple of service bulletins. There is a flawed design that lets oil get pulled in through pcv valve. It requires a different valve cover or 'afm' shield in oil pan.

So had to argue with the dealer for a week before they finally fixed it.

Thanks a million to Kristen from Chevy customer care who saw my original post on here and helped lean on the dealer to do the right thing.

Luckily
