While driving around 65 mph on a highway. The battery light went on. Then suddenly the power steering and brakes died. It was very scary. A hugh safety issue, this very easily could have lead to a serious accident, crash or death. The steering was very difficult to turn and the brakes hard to push down. But the car was still running and luckily I was close to a exit. I pulled off the highway and stopped in store parking lot. It would not start after getting there. I had to have it taken to a Buick dealership. It was also showing a air bag error message. They told me it had to do with the seat position or something like that. I have had it there 6 times this year with the same issue. About 3 weeks ago for the 7th time of taking it there they finally replaced the hybrid battery stating that was the problem. However it worked for only 9 days. When I went to drive it on the ninth day, the battery light was again on and had no power steering or brakes. I left it in my garage, but ultimately had to take it back to the company who has now had it for 2 weeks stating that there is some type of parasitic draw on the batter and it won't hold a charge. They also can't find the issue with what's wrong with the car. This car is not safe and should be recalled.

Vehicle problem starts with tire inflation warning, then seat belt warning and quickly spreads to all systems shown on the instrument panel. All systems stop functioning including turn signals, with only steering, braking, and accelerator operable. Instrument panel may go dark, then resume with same failure lighting sequence. Onstar stops working. Ventilation system may run max heat and or switch to max cold, then shut down (while driving). Last spring vehicle would not allow entry, transmission locked, and was towed to dealer. Early November 2016 tire pressure warning fired (parked). End of January instrument panel went full sequence of warning lights, went dark (while driving). January 26, 2016 (while driving freeway speed) instrument panel ran through sequence of warning lights, gauges fluctuated widely, panel went dark, no controls worked except, brakes, steering, accelerator. To shut off engine (while parked) took three attempts and once off instrument panel continued to displace warning lights. Vehicle towed to dealer.

The contact owns a 2015 Buick Lacrosse. While driving various speeds, "don't take your eyes off the road " began to flash on the message board. The failure recurred on numerous occasions. The vehicle was taken to a dealer. The contact was informed that the message was only supposed to display during vehicle start up. It was diagnosed that a module needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 50....updated 12/28/16 updated 01/03/17.

Takata recall, the engine stalled while driving the car especially during turns. The car continued to hesitate to stall in traffic. The car vibrated nearby the steering column while driving in traffic. The car floor appeared to cave in on the left side on the driver's side. The heater failed to blow out hot air. The telephone calls were distorted as evidenced by being unable to hear the caller.

The contact owns a 2015 Buick Lacrosse. After the contact pressed the start/stop button, the vehicle would not shut off. Also, while reducing speed to stop the vehicle, it suddenly shut off and could not be restarted. On a separate occasion, after shutting the engine off, the vehicle erroneously restarted without the start/stop button being pressed. The vehicle was towed to the dealer, but the cause of the failure was not determined. The manufacturer was not notified. The failure mileage was 2,500. Updated 05/26/16 the consumer stated GM allowed her to trade the vehicle, for a 2016 model. Updated 06/14/16.
