Unannounced to purchasers, the Buick Regal has a redundant and defective security ignition system that prevents the vehicle from being able to start with the key after the battery is disconnected. It must now be taken to a dealership to be diagnosed and for a costly repair. It was stationary, and the battery drained down with a phone charger hooked up. Even following the factory key sequence, the battery runs down before the code can be cleared and re-established.

My 03 Buick Regal ls will shutoff sometimes when turning left, or when using the turn signal. I can not find the paperwork, but I remember a recall for this about 5 to 8 years ago. We did have it addressed, but the problem has come back. Today's date is 1/9/17 and my wife had this happen again to her on 1/4/17 while making a left hand curve. She was not turning or using her turn signal. I only had it happen to me once while making a left turn using my turn signal. My mother also has an 03 Regal gs and also experienced this same problem. I contacted the dealer where I purchased the car and they told me there is no current recall nor was there ever one for this problem, but I know we had it addressed about 5 to 8 years ago.

My ignition key wouldn't come to off position when I turn off the engine. Key wouldn't come out from the ignition cylinder and I had to leave the key in the car and manually lock the car. As a result it would drain the battery and the car is under a high risk of car being stolen and at the times the steering would get locked. Thank you

The vehicle engine shut down and had to be restarted while rolling. Every event usually involved turning and braking at the same time, but occasionally shut down while idling at stop lights. It appeared to be similar to the ignition recalls that have been made on other vehicles, but not on this particular model. It has occurred several times and at least two to three times while turning onto on ramps to freeways. It always requires shifting into neutral to restart and very stiff steering because power steering is disabled. This has occurred in traffic and presented very hazardous conditions. I believe the ignition is at fault, but cannot say positively. Usually occurs when the car has been driven for some time and the engine has been running quite some time and is considerably warm. Under hot conditions it occurs more often.

I have not driven the car for over a year due to it not being on the recall list for the ignition not working. Some thing to do with the ignition and the transmission, you can't get the key out of ignition because it want turn off to the point of removal. I've noticed that there's a click sometimes when you put it in park and then you can remove key but it's rare, I'm afraid it's going to do the same thing the recall says will happen going down the road. (accident) there for I don't drive it the Buick dealership said there were no parts available due to the number of recalls brought in, I've been unable to get help.

My car has had issues with the electrical system. When I use my turning signals my car shuts off and I have to put in neutral and re start it. Also, the ignition issue is preventing my car from starting. I just had my starter replaced 4 days ago because I thought the issue was the starter even one it read okay I went ahead and replaced it since the issue was the car starting along with it shutting off when using the turning signals. I called in due to the recall to find out my car has a recall on another part that could cause it to catch fire. I had the appointment set up to replace that recall but since the car is not on the ignition switch recall I cant get that fixed to even get the car started. It starts most of the time but it seams the times I really need to be somewhere it wont start. Whyis it that my make and model are not apart of the recall if plenty of owners with this car are having the same issues. I have been so close to being in an accident due to this and need it fixed. I am a single mother and feel I should not incur diagnosis test when I can tell you what's wrong and then I have to pay to fix something that has been recalled in many other GM automobiles but not mine. How can I get my car put on the recall list so it can get fixed"??" this is a huge safety issue and it needs to be addressed!
