When starting our 2020 Buick Enclave I noticed the low voltage battery light stayed illuminated after startup. A message followed on the message center located in the center of the gauge cluster. The message read Service Electrical Charging System. Followed by a message stating Low Voltage Vehicle Ma Stall. This particular vehicle only has 38,000 miles on it and I have not experienced any issues with the electrical charging system prior to this incident. There have been no indication as to the battery or alternator failing (ex. dim lights, flickering lights, malfunctioning electronics/electrical equipment, unusual noises coming from engine bay). I acknowledged the messages with the button on the steering wheel. I proceeded to drive and the low voltage light went off shortly after. I proceeded to drive approximately 75 miles without incident. Shortly before arriving at my destination the low voltage warning light illuminated and the messages appeared on the center screen on the instrument screen. I again acknowledged the messages, but this time the low voltage light stayed illuminated until I shut the vehicle off at my destination. I visually inspected the battery post, connections, serpentine belt, and alternator. Nothing looked out of the ordinary and all connections were tight and free from corrosion. Nothing smelled burnt as it would if wiring overheated or alternator. I proceeded to start the vehicle. The vehicle started without hesitation and the low voltage light was not illuminated. I proceeded to drive to a local parts store which was a couple of miles away. On the way to the parts store the low voltage light came on and the messages appeared. I left the vehicle running at the parts store. The employee tested both alternator and battery. The alternator was showing that it was failing only producing 8.6 volts to the battery while the vehicle was running. I proceeded to leave the store. At this point all electrical shutdown simultaneously. Vehicle to be towed.

The rear liftgate locking mechanism failed to latch causing cargo to exit the vehicle where the car behind this car smashed into the cargo causing an accident. For whatever reason the rear door will not lock at all. The fuse was perfectly fine, appears the actuator is defective. No warning was given because the rear liftgate was open and unlatched. After realizing the gate would not close it would notify it was open but the power liftgate operates just fine, and when you activate it, it will push the gate closed and not give a warning until maybe you hit a bump in the road.

OnStar system and WiFi intermittently do not work, was told that this is a known issue when radio is being used, no fix. In my case radio was not being used, so this does not apply. Seat/mirror position memory gradually changes over time. Does not recognize that exit function has been turned off. Signal lights randomly flash (without indicator on dash flashing) when car is at idle & mirrors are folded. Tire Pressure monitoring system, not accurate and will notify driver that tires are underpressured by 10lb or more. Dealership reset them and are now fine. Brakes on passenger front randomly grind since day one of ownership Dealership told me that there is an obvious electrical issue, however since no codes are being thrown, they cannot repair it. Best that can be done is to continue to drive it and show up at a dealership when problems are occurring. OnStar diagnostics was able to determine vehicle was not connecting. Dealership indicated they'd let GM know about the issue, but nothing else could be done for what is a relatively new vehicle. Also was told they would not ensure that vehicle was not affected by structural issues because the VIN was not listed
