Barely three months ago they sold me a BRAND NEW 2015 EQUINOX with electrical issues that GM knew about and has not fixed yet. The whole center section/dash freezes up and cannot be turned on or off. No sound, no stereo, no Bluetooth, no On-Star, the steering wheel controls stop working and all of the the center dash/console lights stay illuminated even when the car is turned off and key is removed. As a result the battery drains overnight and has to be jump started. This car isn't even 3 months old and yet I am told there is nothing that they can do and I just I have to take a chance everyday that I will need to have my car jump started. My only other option-call GM and hope for the best. REALLY?!?!?!
