Fun but not safe
I paid a premium for my used 2021 because they were hard to find in my area. It was my first GMC. I loved the way the 6.2L engine performed, and still do. The problem is all of the “safety “ features. After two months of driving I had a list of thirteen different safety issues. Like the adaptive cruise control not slowing the truck as it approached other vehicles, automatic stop control slamming on the brakes on a turnpike with no vehicles around, etc. My dealer spent three days running down all thirteen issues. The result was twenty five pages of oddball reasons all the safety devices don’t work all the time. Nothing was actually found. I have been driving for three more months still dealing with the same issues. The reasoning used by GMC means you can’t trust the truck to help you out of unseen troubles. And that includes the automatic door locks not locking every time you park.
Early brake pad failure with normal use
Brake pads needed to be replaced at just over 10,500 mi. Dealer said it was due to dirt roads and winter salt on the roads and that it was a common problem. First truck, btu neer had such problems on my Audi, Subaru, Volvos, Jeeps, and Toyotas. Brake pad replacement due to standard road conditions is not "Professional Grade" compared to other vehicles. Apparently brakes are a problem for GMC - look online at all of the recalls - and this is not covered under the warranty. Caveat Emptor!
Good looking truck, and that's about it
Have the 3.0 with about 20k miles. First 6 months drove great, good MPG around 23 average. Now lucky to get 17, they have had to replace the NO2 cat converter, HVAC controls, door seals, updated radio software numerous times because the infotainment will sporadically shut off and go black. Bigger issues are the low gas mileage and it has slowly lost coolant since brand new. 2 years later and I have to fill coolant tank with about 20-30 ounces every couple months. The Def fluid usage is all over the place, sometimes use 2.5gal in less than 1,000 miles, other times get over a couple thousand. Have been to 3 dealerships, say nothing is wrong with it because no check engine codes. Now in contact with GM through BBB autoline, but that is a mess. Stay away from the 3.0 would be my recommendation, and maybe GM altogether. A lifelong GM customer and fan no more, this will be the last one I ever own.
