The vacuum pump failed, causing the gear to explode, which in turn damaged the cam shaft. Yes, this is available for inspection. The brake was unable to be depressed, requiring extreme force to being able to safely stop at an area that was safe to do so. I turned the car off and it made a funny sound. When I tried to start the car, it would no longer start. The car was towed to my local auto mechanic and then to the closest Buick dealership. The dealership diagnosed the problem outlined above. No warning lights.

I had just left the driveway at my in-laws house, which is approx. an hour and 45 minutes from my home. Within moments, randomly, the sun roof popped open, as if someone had hit a remote. It would not close, and after trying for a bit, decided to drive home and we would address it there. When I hit the open road, the roof went the rest of the way open and then about two miles from the house, I starting choking on the smell of burning plastic. I immediately pulled over on to the shoulder of a side road, turning off the car. My husband was in a vehicle behind me and came over and we were both very concerned the vehicle was going to catch on fire. He tried to pull the fuse in the panel, but when we turned the vehicle back on, there was smoke coming from the sunroof motor area, and the smell was atrocious. The inside hood liner was very warm near the rear of the vehicle with the motor. At that point, we decided to call a tow truck, because it was obvious there was an electrical short. Because the sun roof was stuck open, we had to get a car cover to protect it from the rain coming in. The dealership investigated the next day, and confirmed there was an electrical short that was throwing high-voltage power in to the sunroof. It had melted the motor and wires around it, and had we gone any further, the voltage would have caused a more significant fire. They had to do significant repairs, costing $1400, as well as some clean-up of the interior to try and ensure we weren't continuing to breathe burnt-plastic fumes.

When the car is in auto engine shut off mode, when the brake is released the steering power assist message displays, the steering wheel locks up, the doors unlock and the interior and exterior lights flash. The car will start back up but it takes a second to start. The car is also starting to not start back up and completely shut off at the light. All of the lights will start flashing. This is highly dangerous as the steering wheel lock almost caused my family to get into a major car accident. The car will be taken to a dealership later this week.

While driving down interstates and highways, the vehicle's dashboard completely shuts down. The radio, meters, dash display, etc. All go dark and turn off for a span of 5-20 seconds. This has happened multiple times over the couple years of ownership. The vehicle is always going at least 60 mph and, while it doesn't turn the engine off, it does turn the air off and, overall, causes a huge distraction for the driver.

Rear tailgate requires manual operation to open, close, and lock. The vehicle is equipped with automatic lift gate controls on the driver door and also by swiping foot under rear bumper. I have documented four times in the past month that the tailgate will not operate properly. Each time however that I bring the vehicle to the dealership, the tailgate works properly. The mechanic said it is probably the actuator, but until I can bring it to them when it's not working there is nothing they can do. There was one instance were the tailgate wouldn't lock even when manually operated. I had to drive the vehicle with the tailgate unlocked and opening when I slowed down. The dealer sales personnel did a temporary adjustment by turning the vehicle on and off and adjusting the selection knob on the driver door. Your help here is appreciated. The dealership is being very helpful, but can only fix something when they verify that the item needs repair.

When vehicle does automatic software updates from GM, it "blows up" the personalization menu. I am in physical therapy now from car seat that automatically went to position 1 when I opened car door. Easy exit had been turned on by update. I had it turned off because it never worked right with memory seats. Now after another update and menu was skewed again. Easy exit turned back on as well as seat heaters on start up. Both had been turned off in menu.

Car has electronic child safety door locks activated when using the hard button that typically locks only windows. Wife took a nap in back seat on lunch break at work, didn't realize window lock button was accidentally engaged, locked with remote from back seat while car was running. Door remote would not allow the back doors and passenger door to remain locked and door handles would not open from inside even when using the remote. She was trapped in the back. With a very bad back and knee it was not easy to climb to front driver side door to unlock from there, the only place this would work. If locking with the remote, unlocking with remote should be possible and was not. Literally trapped in back seat and only way out is to get to the front seat to unlock from there. What if grandma was back there when something happened like car shut off? very bad situation and a life safety issue. I've never owned a car that had electronic child locks tied to window lock switch. Should not be allowed to be trapped in car.
