Took car to walmart one night and begins to overheat after napa told me it had no leaks. Car overheats I pull aside and turn it off for a bit I noticed the car would crank but hesitate to start. Once got it to start it would accelerate but at low rpms. Check engine light went on and I noticed car shaking and weird noise coming from the engine. Once started car squeaked and mad terrible noise. Car did not turn back on and did not make it home. Cranks and rare when starts, charged battery but drains, doesn't maintain charge. White smoke coming out of exhaust and when car would stall it would turn off, now theft system light is on. Now car wont even crank or turn on. Once I got it to turn on with trouble it would turn off once put into reverse or drive. Turned off while driving it one night and brakes did not work.

Yesterday I was driving on a straight road with a few turns in a rural community. All of a sudden the theft system light starts flashing, my speed drops by force, my steering wheel tightens, and the engine shuts off. Thankfully the driver behind me was not up to speed as he had just turned onto the street after me. Otherwise, he would have slammed into the back of my car. I put the car in park and started my routine of trying to get the ignition to turn over. This process calls for me to put the key in the igntion, turn it to the right, and wait for the board to light up. Once it is lit, the car usually starts again. This is the first time the engine was shut down when the theft light starts to blink. In the past I have had trouble getting the car to start when the light comes on. I have had several ignition switches replaced at the suggestion of their chevy technicians but each spring/summer I continue to have this costly problem. The managers and technicians seem to think that this is not a big issue and that I will need to continue to replace the ignition switches because the car thinks that I am stealing my own car. The only way for me to get the car to start up again is to put the key in the ignition and turn it to the right without actually starting the car. After 5-10 minutes the electrical board lights up and then I am able to start the car. While this car is a 2003 model, I have had this issue since the car was new but gm refuses to do anything about it. The only thing they have done is to replace the key fobs but that obviously is not the issue for many of their customers.

My malibu will start on its own and run without the key. I have found it running several times or attempting to start when the doors are locked and the keys are no where near the vehicle. This is happening when the vehicle is parked. And the horn goes off randomly and now is burned out.
