6000 miles in 6.5 years. Actually, I think it is about 5800 miles, but I rounded up.
Bought it during a "Chevy Truck Month" promo in 2017. I didn't even know they had a shindig going on, I had just seen online that they had this truck and a similar GMC in stock so drove my old truck up there. It was a big party when I got there, food, games, prizes, etc. I played the cash grab game where you use one hand to snag as much paper money as you can out of a machine blowing it all around with a fan. I got $92 from that, then because they were so busy giving away a Traverse in a lottery, I had to wait and wait to get my trade deal done and after the party was over, the owner of the dealership who knew I was buying a fancy truck came out to break down the cash machine and took pity on me waiting and handed me another $50 bill from the box. So a $142 cash rebate. And a free lunch. And a full tank of diesel. I've probably not filled it up more than maybe 7 times since then.
Anyway, even in only 6K miles, I've had the first 3 issues you mentioned. And a few others like an exhaust sensor causing failed regens, and inop heated seats. Have not had the dirty MAP sensor problem yet but am aware of it.
