Well the code was telling me to replace the ignition switch. The current one is rather loose and doesn't turn off all the way with out a little extra which has been causing other electrical issues. And now my steering wheel is leaning and pulling to the left out of nowhere. And these all happen sitting still or moving. Not so bad on the highway but city streets are hell

I own a 2004 chevy impala 3.8l with approx 179,000 milew.my complaint is in relation to the passlock iii system and the overwhelming amount of "no start" complaints from all the different models of gm car owners across the board with this faulty anti-theft system. I live right smack in the heart of the south in a very small town in tennessee and keep in mind, it is really hot and humidity is ridiculous this time of year. I picked up my daughter at a friends house after work, about 5:25 pm last thurday, 9/5/19, and my car died as I'm driving down the road, like the engine jus shut off for no reason at all , I had filled my tank a few days prior and knew that was not the problem. My first thought was to put in neutral before losing much speed and tried to crank several times before hitting my flashers because there were a few cars behind me on a 2 lane road with very little shoulder room to pull over off road. I popped the good to see if I could see or maybe even smell anything that may have caused this problem. I'm making sure my battery cables aren't loose, no fluids leaking or spewing and luckily a state trooper was passing thru and stopped to see if I needed help and turned his lights on so traffic would know there were problems and could slowly go around. To my surprise, after explaining what happened, he said he had this problem before with his daughters car, 2002 impala, and told me to try the 10 minute reset procedure and sure enough, after that 10 minute reset, she fired right home and was able to get home, home had he not come along and already known bout this faulty system prior, my daughter and I would have been stuck for some time on the side of a 2 lane highway in the early september humidity most likely waiting for a tow. Upon researching after, found gm are aware of this problem and should have to fix it, been neglected long enough! Thank you!

I called chevrolet customer service about a recall on the car. I explained the problem with the ignition switch and I were told it was covered under the recall #14v400000 electrical system: ignition. They had it towed to a chevrolet service place to be fixed. I received a call that the problem was not covered under the recall and I was responsible for all charges of the work done on the vehicle. A key was made under the recall and the ignition key lock cylinder was not replaced. I paid the bill and had it towed back. The man that delivered it put the key in the ignition and it would not come out or turn. I do not feel I should be responsible for charges and they needed to change the ignition key lock cylinder. The car was in the driveway and when a person went to start the car the key would not turn and would not come out of the ignition switch. Resulting in the vehicle couldn't be started. I feel this whole recall was handled improperly and I should not have had to be responsible for charges. The frustration of how it was handled I feel they needed to be more professional about the way they handled this recall before they towed the vehicle to a service place and then make me responsible for charges of work done on the vehicle and towing vehicle back not fixed.
