I bought this 2011 Buick Regal with about 53000 miles on it from a private seller. From the day I got it the stereo, clock, navigation have been a problem. The clock doesn't hold the time, stereo turns off my itself or sometimes makes a loud pop noise and doesn't work. The navigation is in the state of Washington, I live in N.Y. the drivers heated seat doesn't work. The bumper to bumper warranty was up 3000 mile ago, at this point. Later, the timing chain needed to be replaced. The motor made a loud knock and would surge, hesitate and stall. With the timing being off, the transmission wouldn't downshift and was hard to stop the car. Two months later the same symptoms re-occurred. The dealer charged me to diagnose and told me it was down 2 quarts of oil. They changed the oil 2 months prior. Now, I noticed the rear brakes are dragging and don't release sometimes. GM, Buick and two dealer won't do anything about any of this. An expensive car that is barely years old with all these problems. I've seen the service bulletins on all off these problems. No help from GM, just index card readers from the philippines who apologize every thirty seconds and make excuses!

While stopped at a traffic light, the affected vehicle's throttle body failed, causing sever shaking, revving of the engine to approximately 1500 RPM, and eventually causing the vehicle to drive itself forward while my foot was firmly depressing the brake. It propelled, out of my control, approximately 3 feet forward. Had I not put the vehicle immediately into neutral while this was occurring, the vehicle would have travel further, out of my control. Had someone been in front of me at the intersection, or if I had not put the car in neutral, preventing the vehicle from entering the intersection, a vehicular collision would have occurred. The exact cause of the failure, per the dealership work order, was "throttle body internal intermittent short."

The passenger side light bulb melted. Bulb can not be replaced because housing is damaged. Contact the dealer and I was told this is not covered by any recalls. I would be responsible for any parts. This is definitely a factory defect and car is not safe to drive. I have ordered part and I'm still waiting for replacement from dealer.

Well first there are a few complaints, first few months, car alarm going off at random, then trunk popped at random, brought in two separate occasions to dealer for service was said to be fixed. Then left signal outage few occasions brought in with the other work, had no idea about the bulbs till this site, then radio on and off intermittent, battery or other car dies charges will drive all day end of day after a battery jump stutters as driving or feels like going to just die. Got home on 7/21/2014 and noticed all the recalls on news had no clue it was this make, model, year, etc., my 18 has driven on numerous occasions (god forbid) ! also I'm reading where this make takes off at random has happened numerous times in drive thru assumed I hadn't applied enough pressure to brake. I'm furious and honestly with young adult drivers scared to death now! ohhh and never received any recall info on this vehicle ever! oh and my key broke to only thing is it bent and had replaced ! and seat was loose also.

When starting the car in the morning, it acts dead, but the battery is okay. After a few tries it does start but then I have the dash light behaving crazy - emergency flashers on and various messages in my center dash. I reset everything to normal and am okay. Upon a restart later in the day, things are usually okay. Being a senior citizen I don't go very far but yesterday, as I was entering a traffic circle, the engine suddenly quit, a huge trailer truck was bearing down on me and luckily the car started back up just in time. The Buick dealer (darby) treated me rudely over a minor problem so now I don't know where to go or what to do for help on this issue.

Navigation system has failed three times including not accepting known addresses and sending you to a wrong address which in one case was a safety issue sending you into an area which was obviously an area of criminal activity that was nowhere near the doctors office we were trying to locate. It will not even accept my home address as a destination location. I have another navigation system in our other vehicle and also a portable system which accepts my address as a destination. I don't feel that this system can be counted on in an emergency and should be recalled or replaced.
