1994 GMC C35 problems

Defect

VEHICLE DESCRIPTION: PICKUP TRUCKS, CREW CABS, UTILITY TRUCKS AND SPORT UTILITY VEHICLES. THESE VEHICLES WERE BUILT WITH THE POLARITY OF THE WIRING FOR THE ZERO ADJUST BRAKE SWITCH REVERSED FROM WHAT WAS SPECIFIED ON THE SWITCH DRAWING. WITH THE REVERSED POLARITY, THE CONTACTS IN THE BRAKE SWITCH CAN WEAR OUT PREMATURELY. THE BRAKE SWITCH WILL PERFORM NORMALLY UNTIL THE BRAKE SWITCH CONTACTS WEAR OUT, RESULTING IN LOSS OF THE BRAKE LAMPS WITHOUT ANY WARNING TO THE DRIVER.

Consequence

THIS WOULD FAIL TO WARN A FOLLOWING DRIVER THAT THE VEHICLE IS BRAKING AND COULD LEAD TO A CRASH.

Remedy

DEALERS WILL REPLACE THE BRAKE SWITCH AND REVERSE THE WIRING.

Defect

THE SEAT RECLINER TO SEAT FRAME ATTACHING BOLTS ON THESE VEHICLES COULD LOOSEN, FATIGUE AND FRACTURE, ALLOWING THE SEAT BACK TO SUDDENLY RECLINE.

Consequence

IF THIS WERE TO OCCUR TO THE DRIVER'S SEAT, THIS COULD RESULT IN A SUDDEN LOSS OF VEHICLE CONTROL INCREASING THE RISK OF A VEHICLE ACCIDENT.

Remedy

DEALERS WILL REMOVE ALL FOAM AND/OR FABRIC SANDWICHED BETWEEN THE RECLINER ASSEMBLY AND THE SEAT FRAME, INSTALL WASHERS BETWEEN THE SEAT RECLINER AND THE SEAT FRAME AT EACH ATTACHMENT POINT, AND INSTALL NEW ATTACHING BOLTS TORQUED TO A HIGHER SPECIFICATION. THESE CORRECTIONS WILL BE MADE TO BOTH THE DRIVER'S AND PASSENGER'S SEATS.

Defect

THE SEAT RECLINER TO SEAT FRAME ATTACHING BOLTS ON THESE VEHICLE COULD LOOSEN, FATIGUE AND FRACTURE, ALLOWING THE SEAT BACK TO SUDDENLY RECLINE.

Consequence

IF THIS WERE TO OCCUR TO THE DRIVER'S SEAT, THIS COULD RESULT IN A SUDDEN LOSS OF VEHICLE CONTROL INCREASING THE RISK OF A VEHICLE ACCIDENT.

Remedy

DEALERS WILL REMOVE ALL FOAM AND/OR FABRIC SANDWICHED BETWEEN THE RECLINER ASSEMBLY AND THE SEAT FRAME, INSTALL WASHERS BETWEEN THE SEAT RECLINER AND THE SEAT FRAME AT EACH ATTACHMENT POINT, AND INSTALL NEW ATTACHING BOLTS TORQUED TO A HIGHER SPECIFICATION. THESE CORRECTIONS WILL BE MADE TO BOTH THE DRIVER'S AND PASSENGER'S SEATS.

Defect

IF BOTH THE LAP-BELT AND SHOULDER-BELT ENERGY MANAGEMENT LOOPS ON THE FRONT SEAT BELT ASSEMBLIES RELEASE AT OR NEAR THE SAME TIME, ACCELERATION FORCES CAN CAUSE THE BUCKLE RELEASE MECHANISM TO ACTIVATE AND ALLOW THE BUCKLE TO SEPARATE FROM THE LATCH.

Consequence

IF THE BUCKLE RELEASED, THE SYSTEM WOULD FAIL TO PROVIDE ADEQUATE OCCUPANT RESTRAINT PROTECTION.

Remedy

DEALERS WILL REMOVE THE STITCHING THAT CREATES THE ENERGY MANAGEMENT LOOP IN THE SHOULDER BELT(S).

Defect

THESE VEHICLES WERE BUILT WITH FRONT SEAT BELT SYSTEMS WITH NO ENERGY MANAGEMENT LOOPS AND MAY NOT MEET THE HEAD INJURY CRITERIA REQUIREMENTS OF FMVSS NO. 208, "OCCUPANT CRASH PROTECTION."

Consequence

IN THE EVENT OF A VEHICLE CRASH, THE OCCUPANTS OF THESE SEATS MAY NOT BE PROPERLY RESTRAINED.

Remedy

DEALERS WILL REPLACE THE RETRACTOR PORTION OF THE SEAT BELT ASSEMBLY(S) WITH ONE HAVING THE NEWLY DESIGNED ENERGY-MANAGEMENT TWIN-LOOP SYSTEM.

Defect

VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS, VANS AND MOTORHOMES EQUIPPED WITH ELECTRONICALLY FUEL INJECTED 6.5L DIESEL ENGINE. THIS IS NOT A SAFETY RECALL IN ACCORDANCE WITH FEDERAL REGULATION PART 573. HOWEVER, IT IS DEEMED A SAFETY IMPROVEMENT CAMPAIGN BY THE AGENCY. THE CAMPAIGN WILL IMPROVE THE OVERALL DRIVEABILITY OF THESE VEHICLES.

Consequence

CERTAIN VEHICLES CAN EXHIBIT SOME DRIVEABILITY CONCERNS SUCH AS POOR THROTTLE RESPONSE, STALLING, MISFIRE, POOR HOT OR COLD STARTING, EXTENDED CRANKING OF A HOT ENGINE, OR STALLING AFTER START. TRUCKS WITH MANUALTRANSMISSIONS CAN EXHIBIT POOR ACCELERATION FROM START OR COULD STALL DURING DECELERATION.

Remedy

DEALERS WILL INSTALL SOME RECENTLY DEVELOPED ENHANCEMENTS WHICH WILL IMPROVE THE OVERALL DRIVEABILITY OF THESE VEHICLES.

Defect

TRUCKS WERE ASSEMBLED WITH THE LEFT-HAND LOWER CONTROL ARM TO FRAME REAR NUT TIGHTENED BELOW THE SPECIFIED TORQUE. LOW TORQUE ON THIS NUT MAY ALLOW THE ATTACHMENT BOLT TO LOOSED AND SUBSEQUENTLY FATIGUE AND BREAK. THE BOLT BREAKAGE CAN CAUSE THE LEFT HAND CONTROL ARM TO SEPARATE FROM THE FRAME.

Consequence

IF THIS OCCURS, A LOSS OF VEHICLE CONTROL AND A CRASH COULD RESULT.

Remedy

DEALERS WILL TIGHTEN THE LEFT-HAND LOWER CONTROL ARM TO FRAME REAR NUT TO THE PROPER TORQUE SPECIFICATION.

Defect

THE SEATS HAVE BEEN ASSEMBLED WITHOUT BOLTS THAT CONNECT THE UPPER SLAVE HINGE TO THE SEAT BACK FRAME, OR WITHOUT BOLTS THAT CONNECT THE SEAT TO THE SEAT ADJUSTER. IN EITHER CASE, THE VEHICLES FAIL TO CONFORM TO FNVSS NO. 207, "SEATING SYSTEMS."

Consequence

THE MISSING BOLTS MAY CAUSE THE DRIVER'S SEAT TO BECOMELOOSE AND IN A SUDDEN STOP OR ACCIDENT MAY SUBJECT THE OCCUPANT TO INCREASEDRISK OF INJURY.

Remedy

DEALERS WILL INSPECT SEATS FOR MISSING BOLTS AND INSTALL BOLTS IF REQUIRED.

Defect

THE BRAKE PEDAL PUSH ROD RETAINER IS MISSING, MISPOSITIONED OR NOT PROPERLY SEATED.

Consequence

BRAKE PEDAL PUSH ROD PROBLEMS CAN CAUSE THE STOP LAMPSWITCH AND THE BRAKE BOOSTER PUSH ROD TO DISCONNECT FROM THE BRAKE PEDAL,RESULTING IN LOSS OF BRAKE OPERATION, AND A VEHICLE CRASH COULD OCCUR WITHOUTPRIOR WARNING.

Remedy

INSPECT VEHICLES TO ASSURE THE BRAKE PEDAL PUSH ROD RETAINER IS PRESENT AND FULLY SEATED IN ITS CORRECT POSITION.
