I've same problems as most everyone else on here. My current problems I think is with the CPI. It will start then immediately stop, then I won't be able to start it again for a few hours only to have the same thing happen again. I won't buy another older SUV from GMC or Chevy again.
To those who are having issues with the EGR valve I have a fix that has worked well for me may help those who have the electronic controlled EGR valve. Try first replacing the original EGR valve gasket with a new gasket that has a small screen in one of the openings. I put mine in and have not had a problem with the EGR since and it has been over a month. O'reilly's sold me mine and I'm sure you can get it just about anywhere. But as far as I know this redesigned gasket is for the electronic controlled EGR. Good Luck.
Would you buy another car from this manufacturer? Don't Know
