2017 GMC YUKON Complaints

I was stopped at a red light in the left hand turning lane and when the light turned green I proceeded to accelerate and the engine would rev but the car would not move forward so I continued to push on the gas when the car jolted forward Violently. I am lucky no one was in front of me because this would have cause a car accident. Turns out the transmission had failed and needed to be replaced which is a common issue for GM however they never owned up to it and refused to pay to for the cost of the replacement and I paid several thousands out of pocket. This is a major safety concern and could be potentially life threatening. GM should recognize this as a recall and take ownership of a failed transmission with less than 100,000 miles.

The contact owns a 2017 GMC Yukon. The contact stated that the A/C System was inoperable. The vehicle was taken to the dealer, where it was diagnosed that the A/C condenser had failed and needed to be replaced. The vehicle was not repaired. The contact related the failure to GM Campaign Number: N162080780. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 57,000.

Tail lights went out. Lifters have been replaced TWICE! While stopped at red light, at take off the vehicles lunges forward. At low speed the vehicle will down shift on it’s own. 80k miles Recently while headed to work, the torque converter went out. 126k This is suppose to be a luxury vehicle and cost entirely to much to be a POS. I honestly thought I had a lemon but it seems to be a reoccurring issue in the entire fleet.

The SUV was stalled after getting in D to drove forward and all of a sudden it’s started with a big jerk and moved forward It went driving ok for them rest of the day but it kept repeating the incident n and off until June 15 when it was stalled on a traffic light I was able to put the emergency flashers and drive it in reverse to a near by parking lot

drivers side tail light flickering and sometimes not working a $900+ cost! I issue with right hand side when suv has 32k miles, seems like this is an ongoing issue, luckily it was still under warranty the 1st time. The AC condenser when out in April, also an know issue with the Yukon, they wanted to charge me $1500 to repair, I was able to find someone to do it for around $600, now the outlet and usb ports seem to not work. I also had an issue with the braking system , dealer couldn't figure it out, I finally found someone to repair it, $500 fix. For what I paid for the Yukon, you would think they would use top of the line parts!

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

Rear LED taillights circuit boards broken. Disabling both Stop tail lights causing serious safety hazard. We had no clue driving around and we didn't have any brake lights another driver had to tell us. So we googled this problem and it turns out that all of 2017 GMC Yukon have the same issue. There's even multiple websites to repair them as well as auto supply stores selling replacements for $1,000 and the dealership wants $1,500. This is a real problem and GM needs to make this right and recall all of these and replace them before somebody gets hurt if they haven't already.

In july 2021 the passenger side tail light stopped working. A certified GMC dealer replaced both tail lights. In Feb 2024 the driver side tail light failed.

There was a pump in the heart of the transmission. The dealer said told me that was leaking fluid. Apparently this was a faulty hose within the transmission which leaked fluid in the transmission. Therefore, my transmission died. This was a severe I could have been a very dangerous situation if my kids had been in the car. I’ve had to pay almost $8000 for the transmission to be fixed and yeah I see that on the line there was some sort of recall but my dealership is saying there was not. I bought this car brand new and I’ve had it for seven years. I’ve never had an issue with the transmission on any of my vehicles ever.
