Hey there,Well this is the third time I have taken it in with a CEL regarding the exhaust. Last time it had three or four codes pulled. Took them three hours and all they did was an exhaust treatment.
They told me this time to drop it off with them instead of wait.
Hey there,Getting it back today thankfully. Not sure what they did but they say its fixed, ill be checking the paperwork when my wife drives it home.
We live in WA. They told her that GMC is basically Chevy so they were able to give her the Yukon. She is getting 20mpg in this beast! It is fun to drive though.
