NHTSA Complaint #11668731 — 2017 GMC YUKON XL

My transmission failed again after being replaced by General Motors certified dealership. The transmission in question has failed again after less than five months being back in service. In 2024 and 2025 my vehicle has been in and out of the service department at other dealerships and they cannot repair the vehicle according to the dealerships they do not have the staff for it. General motors will not stand behind the transmission as they have now labeled it as a part so they will not have to provide transportation. According to dealerships in my area in Michigan, they do not have the staff or the parts to service my vehicle. I contacted General motors customer service multiple times regarding the situation. We truly have a bad transmission again in my vehicle. The transmission in question is a C8 transmission that has failed due to shuttering and downshifting, which the replacement remanufactured transmission for $8000 continues to fail. General motors will not buy back this vehicle or address this ongoing issue. I truly believe I am not the only person with transmission issues as this is a major defect by the manufacturer, which is General Motors. Will you please look into my complaint is this is caused severe hardship to my family. General Motors needs to take responsibility for this failure to the transmission. I’ve had seven other items that have failed also on this vehicle, including the engine. Thank you for your time and consideration looking into this matter. Sincerely [XXX] .
