I purchased a 2017 GMC Denali with 40,000 miles and had to replace the engine at 94,000 miles, due to lifter failure. My first GMC vehicle to give me any problems, I've owned several without any problems, I have continued to pour money into this vehicle dollars after dollar, the 6.2L engine continues to have issues.

I have spent a year trying to get a brand new 2024 to pass smog. GMC keeps telling me to "just drive it" as there is no other way. In Cali there is another way and the dealer is chaging me $900.00 to do it. The truck has not been road legal for a YEAR!. The dealer still can't get it to reset. The BAR is involved and GMC keeps dicking me around. DO NOT BUY GMC you have been warned.

Just horrible. Broke down on the interstate and couldn't even pull off the road because it just stopped running. Dealership says "no codes" and nothing GM will do to find out what caused that life threatening ordeal. Fast forward to 1.5 months later and I get a warning that my transmission needs serviced and will stop shifting soon. Took it in and now it's out of the bumper to bumper warranty so they won't cover the transmission shifter module that isn't in the power train warranty. Of course, had they fixed it 1.5 months earlier, it would have been under warranty. Also, the advisors on the GM customer service line are simply awful. I spoke to many and none of them had a clue of my issues, and the last one verbally abused me, calling me a child and blaming me for the lack of service I was getting. I will NEVER own anything from General Motors again. Period. No way. I've had better customer service at Dollar General.

I am so sick of Chevrolet products I love how you have parts replaced under warranty then drive 75k miles and the transmission and valve body go and Chevrolet customer service say there is no warranty on those parts and they cant do anything for you I’ll never buy or tell people to buy Chevy i would of gave a zero for my review

I purchased a 2026 GMC Yukon in December for my wife, and within 7 months of owning it my engine is blown. The vehicle only had around 4K miles on it, and it hit catastrophic failure on the interstate traveling 75mph with 18-wheelers behind me and my family. Nearly killed my entire family, and the customer support I've recieved has been dismal at best. They never return your calls and when you call, you always get a different customer service rep. They always say, that your rep is not available, or not in the office. A couple of them were so rude, that they just hung the phone up on my wife and I. Also, we requested a buy back, as we've already been without my truck for over 30 days, and of course GMC denied that. When I say, this has been a nightmare, that's an understatement. I wish Congress would step in and do something about this, as this is ridiculous. Millions of customers are complaining about the exact same issues, and nothing is seemingly being done about it. What is it going to take? Multiple families being killed as they travel in this unsafe vehicles? I caution any customers thinking about buying a GM product to stay far away from buying anything remotely related to GM!

BEWARE — My 2021 GMC Yukon needed a complete engine replacement at only 88,191 miles. My Yukon 5.3L was properly maintained, including regular oil changes, and I have the service records to prove it. When it began consuming excessive amounts of oil, I followed GMC/dealership instructions and completed five oil-consumption tests, documenting approximately 3–4 quarts of oil consumption every 500 miles. I then paid approximately $3,000 for an engine teardown and diagnosis. The dealership found no external oil leaks but documented oil contamination in the cylinders, carbon-packed piston rings, cylinder-wall scoring, burrs, and excessive internal wear. The engine requires complete replacement. This truck is not even five years old and hasn't reached 100,000 miles, yet I'm now paying $15,500 out of pocket for a replacement engine. What makes this worse is my experience with GMC Customer Assistance. I followed the steps they asked me to follow and repeatedly requested calls from management, but I never received those requested callbacks. I bought a GMC Yukon expecting a reliable, long-lasting SUV. After this experience, I cannot recommend GMC based on either the reliability of my vehicle or the customer support I received when the engine failed. I have retained the maintenance records, oil-consumption tests, dealership diagnosis, teardown photographs, and repair paperwork supporting my experience.
