I went out to start my car and the light said that it was not reading the key fob because of low battery. I went and got the other key fob which had never been used and had the same result. The car was towed by Chevrolet to the dealer and it has been there for over 3 weeks. They found that it wasn't a faulty key fob but it was the receiver that gets the signal and allows the door locks to open and the engine to start. I tried moving the shift lever, stepping on the brakes, trying the remote start on the key fob and nothing would start the car nor would it lock/unlock the doors. It just kept giving me the notice that it couldn't read the key fob. I called ONSTAR and tried the actions they told me but that did not work either and they said to contact my selling dealer. ONSTAR contacted the Chevy warranty number for a tow truck but at 9PM it was too late for them to make a service call. What if I was out in a parking lot or in a remote area and experienced the same problem with no assistance. I have been trying to find out what the dealer is doing to repair my vehicle but I have to call the GM complaint line in order for them to try and contact the dealer about my car. They finally gave me a rental vehicle since the vehicle is less than 1 year old and only has about 6,000 miles on it.

Vehicle now has about 1200 and when driving, the instrument cluster panel that digital shows your speed, odometer and other information on my vehicle went blank. It is just a black screen. When this happened, it caused the steering wheel controls for radio volume and turning the station to not work. With this, I have no safety features like lane assist now and can't tell my tire pressure.

Headlights flash or stay on either low or hi beam, hatch opens itself, AWD poping, noise in dash, shifting into AWD by itself, transmission not shifting correctly. There is no pattern and it throws no codes. Major electric problems. The keyless entry pad didn't work the day I purchased my car. Had a new one installed 3 programs and now all this started.

While driving the the whole dash goes blank for a few second, then then it reboots and eventually most of it comes back. However, it did this repeat this cycle and cannot tell if my signals are working or what my speed is. I have a video of it happening. The car has 2,700 miles.. I am taking to a dealership
