1999 GMC Suburban Problems

WHILE DRIVING AT LOW SPEEDS OR COMING TO STOP THE ABS SEEMS TO ENGAGE AND CAUSE ERRATIC STOPPING AND EVEN HARD STOPPING AT TIMES. THE BRAKE PEDAL KICKS BACK AND IS HARD TO PRESS DOWN AND STOPPING IS VERY DIFFICULT.

COMPLETE LOSS OF BRAKES COMING UP TO A STOPLIGHT IN MODERATE TRAFFIC. WIDESPREAD HEAVY CORROSION/DETERIORATION OF BRAKE LINES RESULTED IN RUPTURE OF BRAKE LINE OVER LEFT REAR WHEEL. EMERGENCY/PARK BRAKE USED TO AVOID ACCIDENT. CLEARLY A MATERIALS DEFECT IN THE BRAKE SYSTEM, IN MY OPINION. *TR

The original fuel tank in this vehicle way rusty and leaking. I replaced the original tank with a Dorman model 576-372 fuel tank. The tank was installed in September 2021. The tank began leaking in February 2022. A repair shop discovered that the tank was defective and had failed. The Tank was discarded and replaced with a new unit. As no OEM parts are available the replacement was also and aftermarket part. That tank also was defective and began leaking within 90 days. A third aftermarket tank was installed and it also began leaking recently. When these leaks occur the tank fails in such a way that a large volume of fuel is spilled collects under the vehicle. As there seems to be only one company manufacturing these parts there seems be be a large potential that the issue will affect many vehicles.

The original fuel tank in this vehicle way rusty and leaking. I replaced the original tank with a Dorman model 576-372 fuel tank. This tank included a new fuel pump lock ring, which was used to secure a new fuel pump in the tank prior to installation in the vehicle. The lock rung failed approximately one week after installation allowing the fuel pump to raise up out of the tank. At the next fuel up a large volume of gasoline escaped form the fuel pump opening and spilled. The defective lock ring was replaced with a OEM part and was subsequently discarded.

THE DRIVER'S SIDE FRONT AXLE SHAFT SEAL ON THE DIFFERENTIAL LEAKS FLUID, WHICH RUNS ONTO THE HOT EXHAUST PIPE WHICH PRODUCES A SMELL AND A POSSIBLE FIRE HAZARD I BOUGHT THIS 1999 GMC SUBURBAN VEHICLE USED AT CROWN MOTORS IN CHARLEVOIX MICHIGAN ON 02/02/01, WITH 21904 MILES ON IT. ABOUT 6 MONTHS AFTER I BOUGHT THE SUBURBAN I STARTED SMELLING A BURNT OIL ODOR WHEN I WOULD GET OUT OF THE VEHICLE AFTER DRIVING THE VEHICLE. I COULDN'T FIGURE OUT WHAT THE ODOR WAS. ABOUT A YEAR AGO I HAD MY SUBURBAN SERVICED AND WAS TOLD THAT THE FRONT DRIVERS SIDE DIFFERENTIAL SEAL WAS LEAKING. THIS WAS TOLD TO ME AS A QUITE COMMON PROBLEM WITH THIS TYPE VEHICLE. I WENT TO CROWN MOTORS AND TOLD THEM ABOUT THE PROBLEM. I WAS REFERRED TO THE SERVICE MANAGER WHO SAID THAT HE WOULD NOT DO ANYTHING ABOUT THE PROBLEM BECAUSE THE VEHICLE HAD ALMOST 70,000 MILES ON IT. THIS IS MY THIRD GMC SUBURBAN AND I HAVE ALWAYS BEEN SATISFIED WITH THE WAY THAT THEY LAST. I BELIEVE THAT IF GMC HAS A PROBLEM AND POSSIBLE FIRE HAZARD WITH THESE NEWER VEHICLES THAT THEY SHOULD HAVE A RECALL ON THEM AND GET THE PROBLEM FIXED BEFORE A FIRE STARTS AND SOME INNOCENT PERSON GETS TRAPPED AND KILLED BY THEIR PROBLEM. I AM NOT SURE OF THE DATE THAT I CONTACTED THE SERVICE MANAGER AT CROWN MOTORS OR THE EXACT DATE THAT THE LEAK WAS FOUND BUT I AM USING TODAY AS THE INCIDENT DATE. THANK YOU. HOPE YOU CAN DO SOMETHING BEFORE SOME GETS KILLED OR INJURED BY A FIRE. *JB
