I bought a 2006 Infiniti M35x this summer and had it checked out at the dealer without any major problems.
About a month ago, I noticed that, about five minutes after starting the car, a high-pitched beep comes on for about 10 seconds. This happens every time I start the car, and I don't hear it again for the rest of the drive. No dashboard lights come on.
My mechanic says he doesn't know what the problem is. Does anybody know what would cause this to happen? Thanks!
