I am having issues with the immobilizer system. Last night, I go to start the car and all it does it crank but doesn’t start. I see the immobilizer light blinking so I take the key out and then try to restart. Car starts with no problem. But the immobilizer lights keeps blinking and continues blinking the whole time I’m driving. This is the same situation with both keys.

Any ideas?

It's an 03 V6

 

sounds like a dealer issue,,,,,,,,,,,,,there is a bulletin on immobilizer 02-053 issued on sept 2008 .........
