Slipping Gears: Many Yukon Denali owners report experiencing unexpected gear changes or loss of power while driving. Hard Shifting: This problem manifests as harsh or abrupt gear changes, often accompanied by noticeable jolts when shifting from one gear to another. Unusual Noises: Grinding, whining, or clunking sounds when shifting There has been a class action lawsuit for this. I'm not sure why it has not been recalled in all states.

I started noticing issues with my transmission around 55,000 miles on it. It first started with no noticing that it wouldn’t gear down when it needed to, and then when it finally did gear down, it would really jerk the vehicle. I started calling GMC then and questioning and putting in a claim. Just went back-and-forth four months. Now it was getting worse to where I could feel the transmission slipping it wouldn’t kick into upper gear or lower gear. Again, I was still calling GMC and reporting these issues. I was told to take it and have a transmission oil change, which I did costing me $300. I still noticed this problem and I continue to call. I kept being told that they would have somebody call me back which nobody ever called me back to find out specifics. I took it to a GMC garage have them put it on a machine, and I was told that it needed a new transmission and this wasn’t something GMC was covering. This new transmission cost me $6200 and was done on 1/5/25. Please remember this vehicle only had 64,000 miles on it, which is absolutely ridiculous to need a transmission at this mileage. I again had called in January 2025 reporting this and was told someone would call me back and never heard from them.

1.)Rear Brakes are not functioning properly. They still have pads but when you press down to pump the brake it fails. I was told by a mechanic that they other GMC vehicles have had recalls on this, but mine is not showing one. 2.)The suspension on this vehicle has never worked properly. It rides extremely rough. It has some special suspension in it from a shock perspective, but it feels as if it often fails. 3.) I had to replace the torque converter in this vehicle last year, and the fluid that runs through it. Apparently this is a known issue with no recall. 4.) the transmission slips when the vehicle shifts gears. It shifts hard. Also a known issue with no recall.

Tranny failed at 92k miles even though properly maintained. Since new tranny installed by dealer (out of pocket cost) had to return due to tranny slipping into neutral when driving highway speeds and taking foot off gas. Dealer performed TCM and ECM flash updates. Cost out of pocket for programming. Issue came back less than 2000 miles later
