I was at a stop light and the light turned green, I preceded to press the accelerator, I was just starting to move forward and the, peddle seemed to take over with my assistance went all the way down and began speeding up. I tried breaking and the car just kept going and not wanting to slow down and kept gaining speed, I had to put car in neutral and turn engine off. Same day, same trip about 4 miles down the road, I began to slow down (35mph) due to a turning vehicle and when I was clear to accelerate once again, it happened again, again, I tried the breaks, and the car kept fighting the break and kept gaining speed, once again I had to put the car in neutral and turn off the engine, the speeds reached 65 mph. before I was able to place in neutral and turn off the engine. No warning lights, car ran normally until those terrifying moments, no check engine lights on before or after the above experiences. My husband and I's safety was put at risk due to the road's travelers and Deadmans curves and cross sections, it put us at risk with a higher chance of crashing into a vehicle or accelerating before being able to make a turn safely. As soon as I made it home, I called the Buick service center and delivered the car the following morning to the service technician. It is at the Ross Downing Service Station today.

This is a new issue. Upon exiting my car last night. My car would not shift into park. Everytime I cycled the engine and shift to different gears then park. The car stated it need to be shifted into park still. Without it being in park The car could possibly roll down the hill. Also without it being able to be shifted into park. It continued to flash and keep lights and warning sign on. If not being able to shift into park. I could not leave my car until it recognized the car was in park. The car battery would have drained.

Dealership, fixed brakes due to previous recall. Brakes continue to squeal and grind with every stop. Was informed by dealership that they can do no further repair because it is considered a noise and not a safety issue. Grinding brakes are a safety issue!!!
