The speed limit goes in and out to different number so I won't know what's the actual limit. The radio goes in and out so sometimes when it comes back in it scares me. Different signals are popping in and out on the dashboard so I'm not sure about that. This has been happening since I've had the car so the date is when I received the car. The car's dealer said they tried everything and there is nothing else they could could do.

Acceleration is bad, and inconsisten. Also, when shifting gears the shifter button gets stuck everytime never fails. That's a real safety issue considering I accidently bump it, and the car went into manual, while driving. I barely touched it and it moved. This is the last GM car that I will ever buy always something with their cars. The acceleration for this car on the interstate is bad people go around me because it takes so long to accelerate, it also hesitates when accelerating. I've only had this car for about a month.

My vehicle was in motion, straight-line, at 60 mph. This morning on my way to work, my gauge panel went haywire. This isn't the first time it's happened. It's happened many times. I've taken video of this condition and uploaded it to youtube. Https://www.youtube.com/watch?V=ivsdeo8lcr8 when it happens, not only does the speed and RPM's fluctuate rapidly and inaccurately, but the turn signals quit working (safety issue!), and since the traction control light is coming on, I assume it has quit working as well (safety issue). The vehicle is under warranty, and I've had it in to a local Chevrolet dealership (rk Chevrolet, Virginia beach, va) for repair. They were told of the youtube video and they watched it. They then tried to reproduce the problem and couldn't. so the vehicle was returned without a repair being done. The problem is intermittent. I've tried contact Chevrolet in another way but they were unresponsive. Time to try something different. That's why I am contacting you all.

I was driving on the highway at between 55 and 65 mph. The side I was on had a long, steady incline upward. I had set my cruise control to about 63 mph. As I was going uphill the cruise control was supplying fuel to get to and maintain my speed at 63 mph. I was approaching another car in my lane and decided rather than pass, I would slow down. They were going quite a bit slower than me so came up upon them quickly. I pressed the brake to slow down but the brake was hard as a rock. It would not budge so it did not disconnect the cruise control and my car kept accelerating. I panicked and tried to use both feet on the brake. It still would not budge. I was within 2 car lengths of the car in front of me when finally the car reached the speed I had set the cruise control for and the brakes finally depressed. In hindsight, I had options I.e. putting the car in neutral, turning key off, turning to avoid a collision, shutting off cruise control, but this car was new to me, and in that moment I fully expected the brakes to work. Once I was in control, I tried to recreate the problem with no one around, knowing my options now. It happened repeatedly. A service tech also had it happen to them. First attempt at repair did not fix it. Second attempt did. It was a bad check valve. Apparently the check valve let air out of a booster, so I lost my brakes? the check valve also let fluid fill the booster. The master cylinder and vacuum were replaced as well. Looking back, there were signs, but no obvious ones. A random hi-pitched noise (air squeaking out the check valve). Loss of brake fluid. Dealer had to fill it when I bought it and I added some at 6 months. This was a dangerous and scary experience. I question the design to dis-engage cruise control and the quality of the check valves themselves.
