Electrical System problem #1

The rear defroster malfunctioned and caused the rear glass to reach a high temperature, and it started raining outside, and it caused the rear glass to shatter. No known issues before? we come to this conclusion by looking at the black overheating marks on the glass after it shattered.

Electrical System problem #2

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).

Electrical System problem #3

We have suddenly experienced a problem with our 2019 Suburban, seemingly identical to a problem that plagued 2015 gm light trucks and suvs (NHTSA campaign number: 18v586. Gm's own number for this recall is 18289). At low speeds (typically parking lots, under 5 mph), when turning, we intermittenly lose power steering. This is more common when switching directions rapidly such as during a parking maneuver. Simultaneously, headlights and interior lights intermittenly dim. The instrument cluster screen will display random warning messages (“roll window down then up”, etc). The clock time resets as though the battery was disconnected. Our 2019 Suburban has only 68,000 miles and has received all scheduled maintenance. The battery was recently replaced in September 2022 (14 months ago). I have inspected the wiring and found nothing lose.

Electrical System problem #4

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.

Electrical System problem #5

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.
