Will do. I had all the same symptoms occur but the engine was misfiring and rough idling. Hopefully yours was a fluke. Initially they replaced the fuel injector and told me the problem had been fixed. Upon getting in the truck to drive it home all the same lights came on and the exhaust started smoking lol. Been a very frustrating experience but I am hopeful the new engine will put an end to this nightmare.Keep us updated!
We recently took our yukon at4 for a trip and when we were driving around the check engine light came on. It said ESC needed service, ABS and trailer brake needed service. I was like WTF this has to be a glitch. Went to the dealership and they checked the codes and guy was like oh the code cleared itself. He turned it back on and check engine was gone. Drove it home and everything was fine lol
You will be extremely lucky if it is a 2-3 day turnaround. I'd start investigating a rental and also start a text conversation with GM Corporate to get the ball rolling.Yukon XL Denali... at 6,100 MI out running errands the engine starts knocking with rough idle then check engine light comes on. Code says ECM, but after calling dealer they say it sounds like a lifter issue. Estimates a 2 - 3 day turn around... but after reading this thread I'm thinking it might be much longer.
