I looked into a '15 Traverse the other day -- need some more room than what I've got in my econobox.
It had a CEL on during the test drive. Got a quote for the car & my trade. The service shop diagnosed code P0300 and said they performed a software update per TSB that widens the parameters for a cold start. They guessed it threw a code during a recent cold snap. Service admitted that they don't have enough info to know whether it's something more serious like timing chain or coil packs.
Anyone have experience with a 3.6 DI vehicle throwing this, and only this code? I found a few other posts that mentioned P0300 together with other cylinder-specific codes, but nothing for only P0300, particularly for the '15 which I would guess should have had these issues sorted out. At this point it's difficult to motivate myself to move forward with this vehicle.
Thanks much.
