Big transmission problems at 55,000 miles
Former GM customer, 02/03/2021
2019 GMC Yukon SLT 4dr SUV 4WD (5.3L 8cyl 6A)
I had no idea there were any known transmission problems with 2015-2019 GM vehicles, but I'm very aware of that now through personal experience with this vehicle and after having done some research. I drove my previous Yukon (2013 SLT) to 165,000 miles without ANY PROBLEMS at all. I literally just changed the oil and rotated the tires/replaced tires when needed. Nothing else ever went … wrong with the 2013. I decided to trade for the 2019 because it's a beauty, and I fell in love with it. It has been a good and dependable vehicle for the most part, but it started making a harsh whining noise with cold start-ups at about 50,000 miles. The noise seemed to originate underneath the vehicle at about the level of the front seats, and that just got progressively worse in a relatively short amount of time. It was so loud that I was embarrassed to start my car at work if anyone was around. Of course the dealership "couldn't hear the noise" (which is BS because is was obnoxiously loud). I finally told them that I had read about the known transmission issues in this vehicle and I was CERTAIN that there was a transmission problem, and if they didn't figure it out I was going to take all of my future business elsewhere. Lo and behold, they found some pretty significant transmission issues (shocker). Gears were ground down and my transmission fluid was foul-smelling and orange-brown. I hoped for (and requested) a new transmission but they are currently replacing the only the severely damaged parts of my transmission because "that is all they were able to negotiate with my power train warranty company". I plan to trade as soon as I get her back because I feel that I've been deceived from the very beginning, and I should have received a new transmission. I drive a lot of interstate miles, some at night, and I don't trust that this is the end of her issues. I will NEVER buy another GM vehicle, nor will I do business with this dealership again in the future. There is no way that they weren't aware of the likelihood of transmission issues in this vehicle. I feel like they were trying to placate me until my powertrain warranty ran out in 5000 miles, and now they're just putting a bandaid on what I believe is a much bigger problem. It is a BEAUTIFUL vehicle, and I will be really sad to say goodbye to her.
