Year: 2019 Make: GMC Model: Suburban Mileage: Approximately 125,000 miles (purchased under 90,000 miles) 1. Transmission Failure My vehicle is experiencing clear signs of transmission failure, including: •Hard downshifting/clunking •RPM fluctuations while cruising •Shuddering between approximately 30–50 mph •Vibrations while idling •Hesitation and irregular shifting These symptoms have progressively worsened and are consistent with widespread complaints I have found from other 2019 Suburban owners. This appears to be a known issue affecting multiple vehicles. 2. Rear Liftgate / Electrical Malfunction The rear trunk/liftgate has closed on its own without warning multiple times. I have personally been struck in the head several times as a result. This presents a serious injury risk, especially for families loading children or cargo. There is clearly an electrical or sensor malfunction causing this behavior. 3. Automatic Emergency Braking (AEB) System Activating Randomly The most alarming issue is that the automatic emergency braking system has activated on its own multiple times while driving on the turnpike with no obstruction present. This has nearly caused accidents on several occasions. Unexpected braking at highway speeds creates an extremely dangerous situation for both my family and surrounding drivers. These issues are not minor inconveniences — they are serious safety hazards. Sudden braking, unintended liftgate closure, and transmission failure all create significant risk of injury or collision. Given the number of similar complaints publicly reported by other owners, I am requesting that NHTSA formally investigate these defects and determine whether a recall should be issued for affected 2019 GMC Suburban vehicles. I am extremely concerned for the safety of my family and others on the road. Please confirm receipt of this complaint and advise if additional information is needed. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)
