Hello,
This is more a report on how what and were thread than asking for help thread. Kinda out to see if others are seeing these issues.
2017 Sierra 4X4 5.3L engine.
Eng light #1. Mileage 17532 16 June 2018
Location: Phoenix AZ Outside Temp 80 degrees F
First start of the day Light came on.
Dealer replaced #2 fuel injector
Dealer said they have had a rash of injectors going bad in allot of vehicles. So many in fact that GM can't keep up with demand and wait for parts are 4 days. I waited 4 days to get mine and once they had the part it worked fine till today.
Eng light #2. Mileage 17675 30 June 2018
Location: Phoenix AZ Outside Temp 87 degrees F
First start of the day Light came on. This time I had started the truck with the remote. It shut it's self off after about 15 seconds.
I have an appointment with the Dealer Monday.
Oh and for the record, this is the first vehicle I have ever owned that had a Check engine light come on. I have owned probably 20ish cars or trucks in my 52 years. Just found that to be interesting that I have gone this long before seeing one.
