The power steering has issues when turning it seems to not work. Been have this problem for about a year. I've talked to other Buick owners and they have the same problem. I also have electrical issues on the drivers side door panel, where none of the switches work. Just all of a sudden quit.
What was happening was the car would just start downshifting by itself, speed was drastically reduced. It didn't matter how fast or slow I was going but it did happen on the expressway and I went from 65mph to 40 MPH in a matter of seconds. Had been happening for a year and has been to the dealer 5 times, this last time they had it for 7 weeks and required GM tech center support to finally get it fixed. This was not only a safety issue but also a fire hazard. Following is the fix: nec to check other data circuits that might back feed into high speed circuit. Found circuit #6060 back feeding in to circuit 2500 causing itermittent communication loss. Found circuit overload at contact point g110. Was serving as a contact point for nine circuits and overheating, causing high resistance and loss of data communication at times. …
Tl* the contact owns a 2010 Buick Enclave. The contact stated that while operating the vehicle, the audible warning chimes and turn signal clicking sound where not present due a malfunction in the audio amplifier. The vehicle was taken to the local dealer ballas Buick(5715 west central ave, toledo oh.) who diagnosed that an electrical shortage to the audio amplifier had occurred due to the water leaking into the panels of the vehicle and behind the fire wall. The cause of the failure was not determined. The vehicle was not repaired. The manufacturer was notified of the failure but no assistance was offered. The failure mileage was 168,000.
The car shut off while I was driving it, I was starting to go from sitting at a red light and it just shut itself off! I've just purchased this car and already it's a hunk of junk. Also the amount of electrical problems caused by water entering the motor compartment is ridiculous and should be a recall as it's just a bad design. The ac fan motor located above the passenger floor fills with water and ruins the motor. The car shut off today because of shoddy soldering.
11 months after I bought my Buick the engine went out the dealer said it was nothing to do with me the replacement used all my warranty. And there has been one after another problem. My steering wheel locks during turns almost had some real serious finder benders. It's throwing p420 code for bank 2 and now have no sound at all everything works but no blinkers, hazard, seatbelt, backup warning sounds at all with no radio .

Driving down the road at different speeds and conditions door locked go up and down, gauges go crazy, transmission down shifts, engine doesn't die, pull over and everything is fine until it happens again
When the driver seat is moved the service air bag light comes on. When you move the seat again the light goes off.
