Sometimes they don't and it depends if the vehicle is parked uphill or down hill.

Good morning,

There is a fault in the system. There is a code that is set as well. It sounds like you may have a wheel speed sensor that is out. These videos will help us find the problem.

Please run down these guides and report back.

You can get a parts store to read the code for you for free. Once I know the code, I can help narrow the area of failure for you.
