I have a problem with my Buick Century 2007, any mechanics out there?

Question

When I turn the engine off, it takes at least an hour to turn back on. Sometimes it doesn't though. It seems to have a mind of it's own. It only has 40,000 miles on it. Also, I know when it is not going to start up right away when I turn the engine off, the doors will not automatically unlock. It also makes a strange clicking sound when I run the car. People tell me it might be the computer in the car. Does anyone know what this might be and how much it might cost. I don't think it is the starter, because the problem has been a couple of months.

OOPs, it is actually a Buick Century 2004. Duh.

Answer 1

The question as posed does not give enough information, does the engine crank but not start? then it maybe the anti theft system, if it cranks but does not start may be an ignition or fuel problem. The door lock thing is likely to be a broken or weak connector or connection or even the body control computer.

Answer 2

Well sounds like a odd problem. your discription leads me to believe you have a body control module problem. also may have something to do with the factory anti-theft system, which is tied to the body control module. Have it looked at and with the age I can't see why it wouldnt be under some type of warranty

Answer 3

I have a 2010 Cadillac Escalade with almost the same problem. Battery is fully charged, but it won t crank. Makes a one time growl when I turn the ignition on. The door locks won t work either, can t lock and the alarm won t work. Could it be a starter problem?

Answer 4

Check with your local dealer for recall info.
Some of these types of cars have the ignition key programmed to the cars anti theft module and they did have a lot of problems with them.

Answer 5

being only a year old but with 40000 miles i would suspect the original battery and its connections
