On multiple occasions I have driven my car and parked it. When I have returned to the car it will not start. On star diagnostics tells me there is a problem with the transmission, engine and anti brake system and that I am to get it to the dealer/repair immediately. I have had to wait several hours before I can get it started again. I have been in situations where I am in an areas without phone or cell reception to call for help. It has been to the dealer repair shop 4 times and they are unable to correct the problem. They say until they can replicate the problem - they cannot fix it. Finally with this last (4th) visit they were able to replicate the problem twice. But I was informed they have no idea where the problem is coming from and they have no solution at this time. They will return the car to me after 9 days as is with no fix. I am afraid to drive across Colorado for fear I will be stranded.

The air conditioning system does not work. I've had it to the dealers 6 times since July. It does not blow cold air. The compressor has been replaced; the expansion valve has been replaced; the system was drained and recharged. Nothing has fixed the problem.

We have a 2013 Spark. The A/C does not work while the car is at idle or at lower speeds. When driving the car the A/C will begin to cool once you hit about 40 mph. Then when stopped at a red light, stop sign, or drive at speeds lower than the 40 mph, the A/C will stop cooling and blows warm air out of the vents. The dealership has troubleshot once when we had our first oil change in June. They sold us a new cabin filter they said may be blocked by dirt and suggested that there was also a service due at 15,000 miles that might alleviate the problem. We purchased the service suggested, but it did not help. We stopped into the service dept again and they do not know how to fix the problem. They told us that the engineers at GM are still working on a repair for this issue. It is now September and no resolution has been found. The dealership has no new information.

If there is any kind of bump, or rough road the car will loose power for about 5 seconds and the traction control light will come on. I have almost got run over 4 times now. Had in service dept. At dealer 2 time and they say could not duplicate. This is going to get someone killed. Dealer and GM are no help and just say it is a lite car so that's the way it is.

In June of 2013, my A/C stopped working on my 2013 Chevrolet Spark. The car was taken in for warranty service three times. The expansion valve and compressor were replaced and the A/C was partly restored. The A/C will not work while the car is at idle. When driving the car, the A/C will begin to cool the interior and seems to be fine. When stopped at a red light, stop sign, or in my drive way, the A/C will stop cooling and blows warm air out of the vents. A fourth warranty service call was opened for this problem in early July. The dealership has troubleshoot the A/C issue and do not know how to fix the problem.

Buttons on steering wheel that work the cruise control, hands free phone, and radio controls do not light up when lights are on at night. This creates a dangerous situation as the buttons can not be seen in the dark. GM is aware of the situation and has repaired it in models built after October 25 2012, but will not fix it in the models built before then. When I purchased the vehicle in November of 2012, I was not informed of the change before the purchase, leading me to believe that GM and its dealers intentionally mislead me into buying a car that they had already deemed as having an unsafe feature or they would not have changed it.

This vehicle does not illuminate the steering wheel controls. With absolutely no ambient lighting, the interior of the car is extremely dark, and visibility of the controls is non existent. This presents a severe driving hazard, as there are no alternative controls for the cruise. In order to use the controls, you must take your eyes off of the road and blindly fumble, trying to determine which of the ten mounted controls you need to use, thus averting your attention from your surroundings, momentarily. Chevrolet is aware of this problem, as they started illuminating the Nov.12 builds, consequently neglecting a fix for the pre Nov. 13 builds. Of which I am one. I am not comfortable driving under these conditions after dark. An intervention is clearly needed here, as Chevrolet will not act, and even denies the fact that they did indeed perform the upgrade. Hopefully something will be done, before we orphans wind up paying the consequences.

The steering wheel controls (cruise control, audio etc) do not illuminate. After some research, I have found that GM has remedied this issue with models manufactured after November 2012. This is a safety hazard at night because if I use my cruise control, I have to turn on my dome light to see what button to push. I complained to GM and was told that GM is simply not going to do anything about models manufactured prior to Nov 2012.
