My 2022 RST (purchased new on 17 Nov 21) had its first engine failure at 84,957 miles. Over a month and a half later I got the truck back and it ran great until a week ago and the second engine also locked up 14,588 miles later at 99,845 miles. Ironically both failures were 1.7 miles apart, which was a bridge on I-10 and a "shoulder" barely wide enough to pull out off traffic. Both occurred while pulling a trailer. 1st was my RV, 2nd was with my 7x14 enclosed trailer. First time I waited over 4 1/2 hrs for a tow truck, second time over 2hrs.
While I was out of warranty and just outside of the additional extended warranty, the dealership advised me to start a claim with their customer service advisors. Unbelievably to me, the person that I dealt with was a fluent english speaking person residing in South Carolina vs someone on another continent that's never even seen an American pick-up. GM initially "generously" offered for us to pay a mere $8,000 and they'd pick up the rest. The dealership counter-offered at $1,500 and that's what I paid for a new engine, install, and everything else that accompanies it. The final ticket price was over $14,400. Additionally, ALL service has been at their business since new.
Both times, the dealership has been more than generous and put me in a loaner right away, with each of them being a new Silverado LT. Nice rides, but I want MINE back.
This truck is the nicest vehicle I've owned and truly enjoy driving it...when its running. After putting nearly 15k miles on engine number 2, I was feeling good about it as everything seemed to be normal until event #2. I've lost all faith in being able to trust it again. I travel a lot out of town and if either one of these would have happened away from the local area, it would have even been much worse. Of course, as soon as the engine was ordered it is on backorder which is the world we now live in.
