What owners say
I am writing to formally report a serious issue with my 2021 GMC Yukon XL. The vehicle has developed multiple severe problems, including: •Significant loss of engine power •Noticeable engine knocking noises •Transmission slipping while driving •Transmission movement even when the vehicle is at a full stop These issues not only impair the performance of the vehicle but also raise serious safety concerns. The loss of power and the slipping transmission could lead to a dangerous situation while driving, placing both myself and other motorists at risk.
While driving the transmission will slip/hard shift very aggressively causing the rear tires to lock up. This would happen at unpredictable speeds (anywhere between 10mph-65mph), this occurred for about 2 weeks before vehicle ever gave a code. VERY scary and dangerous especially if you are in traffic since it essentially "brake checks" those behind you. The last incident that finally provided a code occurred at 50 mph when the rear tires completely locked forcing the vehicle in park. Could no longer drive the vehicle after this. The error code states that a rear body valve is needed for the transmission which the dealer is unable to get and neither the dealer or manufacturer can provide any estimate of arrival. Has been in the shop for almost 2 months now waiting.
2018 Yukon XL: Safety of family put at risk over faulty transmission. Vehicle used to transport children many times daily. Transmission began slipping with slight lagging. Vehicle assessed by independent service center and we as customers told this is a common issue with GMC vehicles of this year. Service center was able to reproduce and confirm the issue. Total to rebuild entire transmission was $7,377.33. Total transmission failure. Entire transmission had to be replaced at tremendous expense to our family. Transmission began slipping with slight lagging. Engine RPM's would increase with no additional power or speed.
Engine is consuming 3qt oil every 1,000 miles. Has been consuming oil since 34,000 mile mark and the transmission has been slipping where it revs very high before downshifting. GM has asked for an oil consumption test to be done and now we are 9,000 plus miles into it and they still say it's fine. This car is not worth the price. I can't even take it out of town due to needing the oil consumption every thousand miles by GM request. Complained about engine knocking at 22,000 miles and they said it was normal and I know it's not
We purchased a new 2021 GMC Yukon Denali in July 2021.We have had continuous issues with the truck starting almost immediately after we purchased it and ending with a catastrophic engine failure despite only have ~81,000 miles on it. Even more concerning is that the engine failed while my two of my children were driving with 3 of their friends. The car seized up in the middle of a busy road while driving 55 mph. The kids had to coast to the side of a busy road where they exited the vehicle and waited for a tow truck. Despite regular oil changes and maintenance, we have experienced non-stop problems with the truck * Aug 2022 (29,470 miles): Engine wire chaffing relating to the fuel pressure sensor. Transmission slipping. * Oct 2022 (34,220 miles): “Grinding noises” related to brakes. Faulty brake sensor and brake replacement. * Nov 2022 (35,954 miles): Continued “grinding noises” * May 2023 (51,163 miles): Continued “grinding noises” which were again “shrugged off” by the dealership despite us bringing in the truck for the 3rd time related to this issue. Transmission slipping (transmission torn down, clutch assembly replaced, etc.) * Oct 2023 (62,365 miles): Continued “grinding noises” (4th time bringing the truck in for this reason). * Sep 2024 (81,000 miles): Catastrophic engine failure while driving on a busy road at 55 mph. Based on discussions with a wide range of mechanics, dealerships, shops, individuals within the automative industry, we have come to understand that the issues we have been facing with our truck are not unique. To be clear, we have experienced: i) the same problem repeatedly over a short period of time; ii) repeated unsuccessful attempts to fix the same issues; iii) a prolonged period for repairs where we did not have the vehicle; and iv) significant value loss due to catastrophic engine failure. Further, these problems compromised the safety of my family and has significantly disrupted our life.
