Tried to join a Tahoe forum but it wouldn't let me.. anyway here's the issue...
we have a 2009 Tahoe w/7000 miles. Just took it on a 300 mi trip, parked for 3 hours, started up to drive 2 miles and this happened:
1. check engine light
2. shift indicator not visible
3. clicking sound when braking
4. service back-up assist from dic
5. service stabilitrak from dic
6. engine revs when going uphill
7. clunk sound when shifting
8. runs rough

 

Sorry to read that U R hav'in problems with your 2009 Tahoe. It should all be covered under your factory warranty, plus roadside assistance.Without having the test equipment to test for your problems. I would call you closest Chevy GM dealer & have them fix your problems under your factory warranty...Good Luck and let us know what happens `ok : )

2009 Tahoe Warranties


Basic Coverage:3 yr. / 36,000 mi.

Free Maintenance:N/ADrivetrain:5 yr. / 100,000 mi. Roadside Assistance:5 yr. / 100,000 mi. Rust:6 yr. / 100,000 mi.

 

Sounds like the pcm went to crap.

 

man, sux to get stuck with a lemon... do you have the lemon law in your state? or is that in every state?

 

The beauty of having a 2009 Tahoe with 9,000 miles is that you don't need to figure out what's wrong, you just need to know where the nearest dealer is located. It'll be under warranty and it sounds like the computer will have thrown a bunch of codes that only a Chevy dealer is equipped to address. Ah, I remember the good old days when my car was under warranty, I didn't have a care in the world.
