1993 GMC Jimmy brakes complaints
Page 3 of 7: complaints 41 to 70 of 169, newest first, as owners wrote them.
Vehicle always exhibited extremely long stopping distances on any surface whenever ABS engaged. Abs unit failed after an instance of hard braking. Whenever ABS unit would engage, when it was still working, it felt like the truck would just keep going and going and never stop - a very, very scary feeling. It would cost over $1,200 to replace and gm dealer service person had told me that almost every unit had failed at one time or another; gm even reduced price for the replacement due to high demand. There is definitely something wrong with this picture - I paid extra for ABS brakes when I bought the truck and they have been nothing but trouble.
When driving at any speed and applying the brakes they go straight to the floorboard. Vehicle has been at dealer four times ,and the dealer can't determine the cause.
Abs sensors periodically sending erroneous data, causing vehicle to go out of control when braking. After a few minutes it would stop and no lights would shine. After a few days it would happen again. Reported problem to gmc and they said they could find nothing wrong with the vehicle. Many close calls with accidents until ABS system was finally disabled.
When brakes are applied, the pedal becomes hard, which causes extended stopping distance. Manufacturer has been notified.
While coming out of the garage vehicle sudden accelerated while occupant had foot on the brakes. Brakes did not operate, causing an accident.
