2019 Chevrolet Suburban Electrical System Problems

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)

THE 2019 CHEVROLET SUBURBAN IS EQUIPPED WITH A WIPER FOR THE REAR WINDOW. ON AN INTERMITTENT BASIS AFTER THE VEHICLE HAS GONE THROUGH A CAR WASH OR AFTER STARTING FOLLOWING A DRENCHING RAIN, THE REAR WIPER WILL NOT WORK EVEN THOUGH IT IS SWITCH ON WITH THE SWITCH ON THE TURN SIGNAL STALK. IF THE VEHICLE IS RESTARTED, THE WIPER WILL THEN WORK AS IF NOTHING HAD HAPPENED. LIKEWISE, IF THE WIPER DOES NOT WORK AND YOU WAIT A FEW MINUTES, IT WILL WORK AS IT NORMALLY SHOULD.

DRIVING OUR NEWLY PURCHASED 4 WEEK OLD SUBURBAN DOWN I95. FOLLOWING A BATHROOM BREAK AT A REST STOP, WE LOADED UP IN THE CAR, STARTED IT VIA THE PUSH IGNITION AND DROVE DOWN THE ON RAMP ONTO THE HIGHWAY. WITHIN SECONDS, SMOKE BEGAN BILLOWING FROM THE HOOD. A FIRE UNDER THE HOOD ENSUED. WE WERE TRAVELING AT APPROXIMATELY 30-40MPH, WHEN THE SMOKE BECAME SUDDENLY HEAVY. WE PULLED OVER AND PARKED THE CAR ON THE SHOULDER AND ATTEMPTED TO TURN IT OFF. FOR 30-40 SECONDS, THE CAR WOULD NOT TURN OFF, RATHER, IT SHOOK AND SPUTTERED. WE EVACUATED THE CAR AND CALLED THE STATE POLICE WHO ARRIVED SHORTLY THEREAFTER. THE SUBURBAN WAS TOWED TO RICK HENDRICK CHEVROLET IN RICHMOND, VIRGINIA. ABOUT A WEEK LATER, WE WERE TOLD THAT THE PUSH IGNITION IN THE CAR CAUSED AN ELECTRICAL FIRE. CHEVROLET STILL HAS THE CAR AND IS WORKING TO REPAIR, BUT WE HAVE CONCERNS ABOUT TAKING POSSESSION OF A 4 WEEK OLD CAR THAT CAUGHT FIRE. WOULD APPRECIATE CHEVROLET'S ASSISTANCE, BUT THE DEALERSHIP THAT WE PURCHASED THE VEHICLE, KOONS CHEVROLET OF MCLEAN, HAS BEEN NONRESPONSIVE AND VERY UNHELPFUL.
