BRAKE LINE FAILED AT AN INTERSECTION, TOTAL LOSS OF BRAKE PRESSURE. CHEVROLET NOTIFIED, DEALER COULD NOT FIND PROBLEM, PART TOOK A WEEK TO ARRIVE, AND WE JUST FIXED IT AT HOME OUT OF EXASPIRATION FOR THE DEALER, CHEVY WAS GREAT THOUGH, LINE FOUND WORN RIGHT THROUGH. MANY FAILURES WITH THIS VEHICLE. WENT THROUGH 3 BATTERIES AND 2 ALTERNATORS. UPPER BALL JOINT FAILED ON THE HIGHWAY, PARTS DEPARTMENT TRIED TO SAY BECAUSE IT WASNT GREASED, BUT I KEEP IT GREASED, THE BALL BROKE RIGHT OUT THE SIDE, ALL BALL JOINTS REPLACED. IDLER ARM FOUND BROKEN WHEN VEHICLE TAKEN FOR RE-ALIGNMENT BEFORE THAT. VARIOUS ELECTRICAL FAILURES (SUSPECTED SHORT SOMEWHERE AS BATTERY SPARKS WHEN RECONNECTED). FUEL PUMP FAILURE AT 65,000 MILES, PRECEEDING FUEL GUAGE MALFUNCTION ABOUT 6 MO'S BEFORE, REPLACED FUEL PUMP. HEATING FAILURE SUSPECTED DUE TO DEX-COOL COOLANT (COOLANT SOLIDIFIES AND JAMS HEATER CORE, ECT...), VEHICLE REVERSE FLUSHED, AND NEW THERMOSTAT INSTALLED, NOT MUCH IMPROVEMENT, BLOWS HARDER BUT STILL COLD. TRANSMISSION SLIPS ON OCCASION. CURRENTLY LEAKS STEERING FLUID, THIS HAS NOT BEEN CORRECTED AS I BOUGHT A NEW TRUCK, AND HAVE NOT HAD TIME TO FIX THE S10. WATER COMING IN FROM SOMEWHERE, CARPET CONSISTENTLY SOAKED. VERY UNHAPPY WITH VEHICLE WITH SO MANY REPAIRS, TRUCK ONLY HAS 70,000 MILES, COMPONENTS FAILED FAR BEFORE THEIR TIME, MORE MINOR THINGS WRONG BUT REPAIRED. WE ARE LUCKY TO HAVE A GARAGE AND A WHOLE LOT OF TOOLS FOR THIS VEHICLE. *AK

PASSLOCK FAILED ON SEVERAL OCCASSIONS. DEALER REPAIRED EACH TIME AT NO CHARGE(WARRENTY) BRAKES FAILED BEFORE 15000MILES, HAD TO REPLACE BOTH FRONT ROTORS. DEALER REFUSES TO ACKNOWLEDGE ANY FAULT OR REIMBURSEMENT. WE BELEIVE THAT SINCE THE MILLAGE IS SO LOW, THE DEALER SHOULD REIMBURSE US FOR THE REPAIRS.

Official recalls
4Sep 8, 2000
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES WERE BUILT WITH INCORRECT PAYLOAD INFORMATION ON THE VEHICLE CERTIFICATION LABEL. THE PAYLOAD SHOWN ON THE LABEL IS GREATER THAN THE MAXIMUM VALIDATED PAYLOAD. IF THE VEHICLE WERE LOADED TO THE INCORRECTLY LABELED PAYLOAD, IT MAY NOT RIDE AND HANDLE IN THE MANNER THAT THE DRIVER EXPECTS.
Consequence & remedy
Consequence: THIS COULD RESULT IN A LOSS OF CONTROL OF THE VEHICLE OR AN INABILITY TO STOP THE VEHICLE WITHIN EXPECTED STOPPING DISTANCES.
Remedy: OWNERS WILL BE SENT A NEW LABEL FOR INSTALLATION ON THE DRIVER'S DOOR OF THE VEHICLE.
Aug 7, 2000
VEHICLE DESCRIPTION: PASSENGER VEHICLES, LIGHT DUTY TRUCKS, SPORT UTILITY VEHICLES, AND MINI VANS EQUIPPED WITH TRW SEAT BELT BUCKLE ASSEMBLIES. THE BUCKLE BASE OF THESE SEAT BELT ASSEMBLIES WERE NOT PROPERLY HEAT TREATED AND THEREFORE DO NOT PASS THE LOAD BEARING REQUIREMENT OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 209, "SEAT BELT ASSEMBLIES."
Consequence & remedy
Consequence: IN THE EVENT OF A VEHICLE CRASH, THE OCCUPANT MAY NOT BE PROPERLY RESTRAINED.
Remedy: DEALERS WILL INSPECT THE VEHICLE'S SAFETY BELT BUCKLE ASSEMBLY DATE CODES AND, IF NECESSARY, WILL REPLACE ANY SAFETY BELT BUCKLE ASSEMBLY.
Feb 28, 2000
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS EQUIPPED WITH 4-WHEEL DISC BRAKES. SOME OF THESE VEHICLES HAVE AN ANTILOCK BRAKE SYSTEM (ABS) MOTOR CONTAINING AN OUT-OF-SPECIFICATION SPRING CLIP. THIS CLIP COULD ALLOW THE MOTOR BEARING TO BECOME MISALIGNED. IF MISALIGNMENT OCCURS, EVENTUALLY THE ABS WOULD BE NON-FUNCTIONAL.
Consequence & remedy
Consequence: THE BASE BRAKES WOULD REMAIN FULLY FUNCTIONAL, BUT THE DYNAMIC REAR PROPORTIONING (DRP) SYSTEM, WHICH OPTIMIZES FRONT TO REAR BRAKE BALANCE, WOULD BECOME INOPERATIVE.
Remedy: DEALERS WILL REPLACE THE BRAKE PRESSURE MODULE VALVE ASSEMBLY.
Aug 11, 1999
VEHICLE DESCRIPTION: S -TRUCKS EQUIPPED WITH 2 WHEEL DRIVE. THESE VEHICLES MAY HAVE HAD THE RIGHT-HAND ANTILOCK BRAKE SYSTEM (ABS) MODULE FEED PIPE AND/OR BRAKE CROSSOVER PIPE TUBE NUTS TIGHTENED WITHOUT SEATING THE PIPE-FLARED-ENDS ENOUGH TO WITHSTAND NORMAL ASSEMBLY AND VEHICLE INPUTS WITHOUT PARTIALLY UNSEATING. THIS DOES NOT COMPLY WITH REQUIREMENTS OF FMVSS NO. 105, "HYDRAULIC SERVICE BRAKE NORMAL, EMERGENCY, AND PARK BRAKING PERFORMANCE."
Consequence & remedy
Consequence: IF THIS OCCURRED, THE SEATING SEAL COULD BE BROKEN DURING VEHICLE ASSEMBLY, OR FROM EARLY ROAD INPUTS OR BRAKE FLUID CYCLING, AND A LEAK COULD OCCUR INCREASING THE BRAKE STOPPING DISTANCE.
Remedy: DEALERS WILL INSPECT THE BRAKE PIPE UNION FOR SIGNS OF BRAKE FLUID, AND IF NECESSARY, INSTALL A NEW BRAKE PIPE UNION.
