Dealership had to replace my fuel injectors and advised me not to use VALERO fuel due to the black residue their fuel contains. Supposedly this has happened to many people and damaged many vehicles.
Supposedly another coil went bad. This is the third time a coil has needed to be replaced. It is a very expensive repair. I would gladly get rid of my GMC Acadia if I could.

Engine light/ code: cam shaft sensor problem and detected miss fire. Well known timing chain problem.

Check engine light on. Dealer reset and stated they couldn't find a problem associated with codes. Check engine light came on 4 days after leaving dealer. Took to a different dealer (on a road trip). That dealer stated that the codes were "old" and reset the light. After we returned home we took the Acadia to our selling dealer. They had to keep it for 4 days and were eventually able to replicate problem (engine light, rough handling) and replaced fuel injector 1. No problems since.
Cooling fan would engage and run excessively during driving and after the car would be turned off. Fix targeted to cooling pump.
This was a warranty related repair.

Check engine light on, dealer was unable to find the problem. Also had a problem with the car appearing to start and then when I put into gear it would die.
