Recall 05V3790001,353,718 vehiclesopened after NHTSA action (ODI)

Problem: CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES MAY EXPERIENCE UNWANTED ANTILOCK BRAKE SYSTEM (ABS) ACTIVATION. THIS CONDITION IS MORE LIKELY TO OCCUR IN ENVIRONMENTALLY CORROSIVE AREAS. THIS RECALL WILL BE LAUNCHED IN THE "SALT BELT" STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MARYLAND, MASSACHUSETTS, MAINE, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN AND THE DISTRICT OF COLUMBIA ONLY.
Risk: THIS CAN CAUSE INCREASED STOPPING DISTANCES DURING LOW-SPEED BRAKE APPLICATIONS, WHICH COULD RESULT IN A CRASH.
Fix: DEALERS ARE TO REMOVE THE WHEEL SPEED SENSOR AND THOROUGHLY CLEAN THE WHEEL SPEED SENSOR MOUNTING SURFACE ON THE BEARING, APPLY RUST INHIBITOR TO THE CLEANED SURFACE, GREASE THE MOUNTING SURFACE, REINSTALL THE WHEEL SPEED SENSOR, AND CHECK THE PEAK-TO-PEAK OUTPUT VOLTAGE TO ENSURE THE WHEEL SPEED SIGNAL IS WITHIN SPECIFICATIONS.

Delivery › Fuel pump

Recall 05V155000316,508 vehiclesopened after NHTSA action (ODI)

Problem: CERTAIN TRUCKS AND SPORT UTILITY VEHICLES WERE BUILT WITH FUEL MODULE RESERVOIR ASSEMBLIES THAT CONTAIN FUEL PUMP WIRES CONNECTORS MAY OVERHEAT UNDER CERTAIN OPERATING CONDITIONS.
Risk: IF THE IGNITION CIRCUIT WIRE IS EXPOSED, THE FUEL PUMP FUSE WILL BLOW, DISABLING THE FUEL PUMP AND CAUSING AN ENGINE STALL OR NO-START CONDITION. IF SUFFICIENT HEAT IS CONDUCTED TO THE PASS-THROUGH CONNECTOR, A HOLE IN THE CONNECTOR MAY RESULT, WHICH MAY CAUSE A 'SERVICE ENGINE SOON' LIGHT TO BE ILLUMINATED DURING THE EMISSION SYSTEM DIAGNOSTIC ROUTINE. FUEL VAPOR AND IN SOME CASES LIQUID FUEL MAY LEAK OUT OF THE FUEL TANK THROUGH THE HOLE IN THE CONNECTOR BODY. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE. ALSO IF THE IGNITION CIRCUIT OR GROUND WIRE IS EXPOSED AND SHORTS TO THE FUEL LEVEL SENDER CARD WIRES, INACCURATE FUEL LEVEL READINGS MAY RESULT.
Fix: DEALERS WILL REMOVE THE FUEL TANK, AND REMOVE THE MODULE RESERVOIR ASSEMBLIES FROM THE TANK, AND INSTALL A NEW SERVICE KIT FREE OF CHARGE. AN INTERIM LETTER TO OWNERS WAS MAILED ON MAY 25, 2005. THE OWNERS WERE RE-NOTIFIED ON OCTOBER 19, 2005, SINCE PARTS ARE NOW AVAILABE. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 AND GMC AT 1-866-996-9463.

Recall 05V00500098,221 vehiclesopened after NHTSA action (ODI)

Problem: SOME PICKUP TRUCKS, VANS, AND SPORT UTILITY VEHICLES EQUIPPED WITH A HYDRAULIC PUMP DRIVESHAFT THAT CAN FRACTURE, RESULTING IN IMMEDIATE LOSS OF HYDRAULIC POWER STEERING ASSIST. ON CERTAIN VEHICLES EQUIPPED WITH HYDRO-BOOST POWER BRAKES, THE SAME CONDITION CAN RESULT IN LOSS OF POWER ASSIST FOR BRAKING AFTER THE RESERVE PRESSURE IS DEPLETED.
Risk: AN INOPERATIVE PUMP CAN CAUSE INCREASED STEERING EFFORT, AND IN HYDRO-BOOST EQUIPPED VEHICLES ALSO INCREASED BRAKING EFFORT, BUT DOES NOT COMPLETELY ELIMINATE THE ABILITY TO STEER OR SLOW THE VEHICLE.
Fix: DEALERS WILL REPLACE THE HYDRAULIC PUMP. THE CAMPAIGN BEGAN ON FEBRUARY 14, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463.

Recall 02V178000525,254 vehicles

Problem: ON CERTAIN PICKUP AND UTILITY TRUCKS, SOME OF THESE VEHICLES HAVE AN AIR BAG SENSING DIAGNOSTIC MODULE (SDM) WHICH CONTAINS AN ANOMALY THAT COULD RESULT IN THE DRIVER AND PASSENGER'S AIR BAG FAILING TO DEPLOY DURING CERTAIN FRONTAL CRASHES.
Risk: IN A VEHICLE CRASH, FRONT SEAT OCCUPANTS MAY RECEIVE MORE SEVERE INJURIES.
Fix: DEALERS WILL RECALIBRATE THE SDM ON THE AFFECTED VEHICLES. OWNER NOTIFICATION BEGAN AUGUST 28, 2002.

Recall 00V3450001,383,922 vehicles

Problem: VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES HAVE A CLEARANCE CONDITION BETWEEN THE FRONT RIGHT-HAND BRAKE PIPE AND THE BODY CROSS SILL THAT COULD DECREASE TO THE POINT OF ALLOWING CONTACT DURING THE LIFE OF THE VEHICLE. IF CONTACT OCCURS AND THE BRAKE PIPE BECOMES DAMAGED, IN HALF OF THE BRAKE SYSTEM THERE CAN BE A LOSS OF BRAKE FLUID AND PRESSURE. THE BRAKE WARNING LAMP WILL BE ACTIVATED WHEN THE BRAKE FLUID LEVEL REACHES THE INDICATOR LIMIT.
Risk: DURING BRAKING, THE PEDAL WILL BE LOWER THAN NORMAL AND STOPPING DISTANCES WILL BE LONGER. IF THIS OCCURS WHEN STOPPING DISTANCE IS LIMITED, A CRASH COULD OCCUR.
Fix: DEALERS WILL INSPECT THE FRONT RIGHT-HAND BRAKE PIPE FOR WEAR. IF THERE ARE SIGNS OF WEAR, THIS SECTION OF THE BRAKE PIPE WILL BE REPLACED WITH A NEW DESIGNED BRAKE PIPE SECTION. IF THERE ARE NOT SIGNS OF WEAR ON THE BRAKE PIPE, THE DEALER WILL INSTALL A SPACER CLIP TO ENSURE SUFFICIENT CLEARANCE BETWEEN THE BRAKE PIPE AND THE BODY CROSS SILL.

Tires › Sidewall
Tire Size: 265 70 16. While driving on a straight and level highway, the right rear tire sidewall completely shredded. Tire lost all air pressure and separated from the rim. I bought four General Grabber tires in July 2021. This is the second tire that the sidewall shredded. The first one shredded on the left rear side in July of 2024. There are a lot of General Grabber tires being recalled for over-cured sidewalls but it's strange that there are no recalls on this particular tire.

THE FIRST TIME THE ABS EBCU FAILED WE HAD ONLY OWNED THE CAR A FEW YEARS. WE FIGURED OUT SOMETHING WAS WRONG BY THE CONTINUOUS GROWLING BUZZ UNDER THE VEHICLE. WE HAD TO FULL THE FUSE TO DISCONNECT THE UNIT TO PREVENT IT FROM RUNNING DOWN THE BATTERY WHILE WE TRIED TO LEARN EXACTLY WHAT WAS WRONG. ----------- ON THE GOOD SIDE, THE CAR RUNS FINE WITHOUT IT. ON THE BAD SIDE, EBCU REPLACEMENT IS A RIDICULOUSLY EXPENSIVE REPAIR. GM CHARGES $1400 FOR THE STUPID PART, THE TOTAL WAS JUST UNDER $2000 BY THE TIME ALL WAS DONE.----------- IT WOULD BE ONE THING IF THE EBCU WAS SOME GREAT INVENTION THAT REALLY IMPROVED THE HUMAN CONDITION.
