Please also check out the statistics and reliability analysis of the 2003 GMC Sierra 1500 based on all problems reported for the 2003 Sierra 1500.
76000 miles; issue ongoing beginning in November 2018 on dry pavement at low speed (under 10 mph) braking is compromised by abs system engagement issue. Below 10 mph, the abs system engages causing dry pavement braking to be double or triple the normal distance to stop prior to the abs issue. This is a safety issue since abs system pulsing of the brakes at slow speeds on dry pavement is unexpected. At a stop sign/crosswalk, this has caused a very close encounter. Vehicle has less than 80000 miles and has been serviced routinely by a certified mechanic. Replacement/service of abs speed sensors and rust issue did not correct the problem. I have never been contacted regarding the recall that exists for this issue. Require assistance to determine why a vehicle with this mileage has this obvious safety issue and gm has provided no relief.
