Consumer Description

Most times when going down long grade over 6 + percent a dash warning comes on about service brake system. Once we get to flat area and turn ignition off the message goes away. We haven't had an issue braking. We are on Facebook group with other promaster 3500 and over 80 other similar vehicle owners stated this happens to them. Everyone says it's a "known problem" and not an issue and just ignore. We are worried what happens if it really is a problem. It happens every time we do mountain driving. I'd say over 10 times this year.
