Stabilitrak light comes on intermittently for no apparent reason. Have had brake fluid, brake pads, rotors, sensors and tires replaced. Traction control and ABS checked; all is good. No cel code relating to this issue. Traction control off button doesn"T work once light appears. There is no difference in driving when light is on. Still haven"T figured out what causes it. Battery, power cords, and alternator have both had to be replaced do to issues with the voltage outputs. Now to replace fuse box and ECM due to more voltage output issues. Cel has had no indications of an ECM, fuse box, alternator, or battery problem until they were beyond repair (this also happened with other transfer case leak, loss of reverse gear, and front differential leak). Cel comes and goes by itself at anytime with no difference in drivability or conditions. Each time it reappeared it?S thrown different sensors and/or circuits failing or high/low voltages including O2, maf, tps, evap system, wheel speed, fuel pressure, oil pressure, steering wheel, gas and brake pedal position, air bag impact, just to name a few. My car has recently started going into limp mode at random due to this electrical issue. Only remedy for this problem is disconnecting the wiring harness and allowing the fuse box and ECM to cool down. And finally, my oil filler tube seal broke and oil was spitting out into engine bay. Coincidentally, my PCV valve tube had also broken, and the tube was hanging loose right in front of the oil filler tube. As a result, PCV tubing sucked up a large amount of oil into the air intake; with no check engine light illumination indicating any problems during the time of failure. My air intake system is nearly ruined (not to mention the $$$ I shelled out in oil) and the wear down on parts has been detrimental to the life of the engine. This car is nothing but a cash cow for GM.

Vehicle was serviced for a faulty fuel level float sensor, which was registering that there was no fuel in the gas tank when the tank was full. 7 days later, while driving on a busy freeway, all of the gauges on the gauge cluster started spinning out of control and the vehicle lost complete power while driving 65 mph. I had to merege across 4 lanes on the freeway in heavy traffic and nearly got run over. No power to the engine at all - it just died while I was driving. Of course, onstar and the Chevrolet dealer that performed all of the service on the vehicle were no help. While waiting for onstar, my vehicle was towed off the freeway.

On two occasions now within a two week time frame, vehicle shuts off while driving. Both times I was in motion at approx. 25 to 35 mph. Get it over to put in park and it does start up so far. I have children and I commute on an extremely busy freeway. What if this failure occurs while I'm moving at 70mph plus? my mechanic has replaced some parts in hopes it was the problem. The check engine light is on/off for months but nothing of a major concern is showing up on the computer. I understand this vehicle has 150K miles but it should not be shutting down while driving. Please help.

The engine will just shut off when I am driving, I have two young children and am concerned that this could cause an accident when driving. I have not been able to get any help from the dealer where I purchased the vehicle even to do a diagnostic on the vehicle.
