One problem related to brake abs warning light has been reported for the 2008 Jeep Patriot. The most recently reported issues are listed below.
My vehicle was in motion in a 45 mph zone when, twice today, the brakes on my 2008 Jeep Patriot sank to the floor and braking was significantly reduced. I didn't even have to pump the brakes to get them to regain pressure after letting off the pedal; brakes worked on second attempt. Later down the road the failure occurred a second time. When I attempted to pump the brakes to build pressure, it was unnecessary . . . The brakes worked on second attempt. My vehicle did not display any warning indicators at the time of the failure; neither the brake like, abs light, or any other lamp on the dash was illuminated when the brakes failed. Usually in the rain, my Patriot suffers from a stuttering and stalling issue that is reported by many Jeep Patriot owners, and has not been solved due to the irregularity of the problem. A direct cause for the issue is unknown and cannot be identified by the dealership or my regular mechanic.
