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.

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!!!
