I've had this car for only 2 years and there is always something wrong. First I was driving and it just shut off all the light on dash board went off and from that point on nothing on the steering wheel works. No horn and none of the controls of it are working. My passenger air bag light stays on. Been in the shop 3 times still not working. Now the warning light of over heating come on everytime I have to still in traffic on my way home or driving for a over an hour, have to turn the heater on, on high to get the light and warning beeping to stop. It's already 90°, but if I don't the car start shaking. The reason I bought a newer car was to not have to put it on the shop every 4 months. So no horn, cruise control, not sure if air bag work on passenger side and to top it off have to ride with the heat on while it's 90°outside to make it home safe, ,(I think,,). . I call gm customer services over and over again, and they tell me there is not other problems with other cars. My warranty is expired. So it's on me.
