THIS IS A PRE-CAUTIONARY COMPLAINT AS A RESULT OF MY SHOCK REGARDING GM'S 8.1L ENGINE IN THE SUBURBANS. ALSO WOULD APPLY TO SILVERADO HD AS WELL. THE VEHICLE IS USING EXCESSIVE OIL WHICH TO MY SURPRISE GM SAYS IS NORMAL. OIL USAGE IS 1.25 QTS PER 2000 MILES AND GM INDICATED THAT THE VEHICLE COULD USE AS MUCH AS 1QT PER 1000 M…

THIS IS A PRE-CAUTIONARY COMPLAINT AS A RESULT OF MY SHOCK REGARDING GM'S 8.1L ENGINE IN THE SUBURBANS. ALSO WOULD APPLY TO SILVERADO HD AS WELL. THE VEHICLE IS USING EXCESSIVE OIL WHICH TO MY SURPRISE GM SAYS IS NORMAL. OIL USAGE IS 1.25 QTS PER 2000 MILES AND GM INDICATED THAT THE VEHICLE COULD USE AS MUCH AS 1QT PER 1000 MILES (ASSUMING 10 MILES TO THE GALLON). THE CONCERN IS REGARDING EMISSIONS DURABILITY AND INDIRECT FAILURES AS A RESULT OF THIS OIL LOADING INTO THE EXHAUST AND CATALYTIC CONVERTER. GM WOULD NOT PROVIDE DETAILS TO ME BUT, INDUSTRY NORMS ARE ASSUMING WORST CASE 1/2 OF THIS LEVEL OF EXPECTED OIL USAGE. GM WAS UNCONCERNED AND HAS A BULLETIN FOR THEIR DEALERS STATING THIS. I FEEL THIS SHOULD BE INVESTIGATED BOTH FROM A SAFETY STANDPOINT FOR POTENTIAL ENGINE FAILURE AND FOR EMISSIONS DURABILITY AND ENVIRONMENTAL COMPLIANCE. *JB
ON CERTAIN TRUCKS EQUIPPED WITH AN 8.1L V8 (RPO L8-VIN G) ENGINE HAVE A CONDITION IN WHICH THE ENGINE FUEL RAIL PULSE DAMPER RETAINER CLIP MAY FRACTURE RESULTING IN INADEQUATE RETENTION OF THE DAMPER.
Consequence & remedy
Consequence: IF THE DAMPER COMES LOOSE, A FUEL LEAK MAY RESULT. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Remedy: DEALERS WILL REPLACE THE ENGINE FUEL RAIL PULSE DAMPER RETAINER CLIP FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 31, 2006. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 AND GMC TRUCKS AT 1-866-996-9463.
ON CERTAIN CREW CAB PICKUP TRUCKS AND SPORT UTILITY VEHICLES, THE 2ND ROW CENTER OCCUPANT SEAT BELT ROUTING MAY MAKE IT DIFFICULT TO POSITION THE LAP PORTION OF THE SAFETY BELT LOW AROUND THE HIPS OF OCCUPANTS, ESPECIALLY SMALLER OCCUPANTS, SEATED IN THIS POSITION. APPROPRIATE USE OF A CHILD SEAT OR BOOSTER SEAT, AS RECOMMENDED FOR SMALL CHILDREN, DOES IMPROVE THE FIT CONDITION FOR THIS USER GROUP. IN ADDITION TO INSTRUCTIONS ON PROPER INFANT AND YOUNG CHILD RESTRAINT (WITH CHILD SEATS OR BOOSTERS), SPECIAL VERBIAGE FOR RESTRAINING OLDER CHILD IS INCLUDED IN THE OWNER'S MANUAL. ALSO, THE SUGGESTED SEAT BELT FIT/ROUTING FOR ADULTS, IRRESPECTIVE OF SEATING POSITION, IS DESCRIBED IN THE OWNER'S MANUAL TEXT.
Consequence & remedy
Consequence: A LAP PORTION OF THE SEAT BELT ROUTING THAT IS NOT LOW AND SNUG ON THE HIPS CAN ALLOW THE LAP BELT TO RIDE UP ON AN OCCUPANT'S ABDOMEN INSTEAD OF FITTING LOW AROUND THEIR HIPBONES, AND THEREFORE, CAN EXPOSE THEM TO MORE RISK OF ABDOMINAL AND INTERNAL ORGAN INJURY.
Remedy: DEALERS WILL CUT OPEN THE GUIDE LOOP, REMOVE A PORTION OF THE LOOP, AND THEN THE REMAINING TWO SIDES SHOULD BE FOLDED OVER AND SECURED WITH A RETAINER FREE OF CHARGE. THE RECALL BEGAN ON JULY 21, 2005. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, OR HUMMER AT 1-800-732-5493.
ON CERTAIN SPORT UTILITY VEHICLES, THE BRAKE PEDAL PUSHROD RETAINER MAY BE MISSING. IF THE RETAINER IS MISSING, THE BRAKE BOOSTER PUSHROD COULD DISENGAGE FROM THE BRAKE PEDAL.
Consequence & remedy
Consequence: THIS COULD RESULT IN A LOSS OF BRAKES WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL INSPECT THE VEHICLES FOR THE BRAKE PEDAL PUSHROD RETAINER AND INSTALL ONE IF IT IS MISSING FREE OF CHARGE. THE MANUFACTURER BEGAN CONTACTING OWNERS BY TELEPHONE ON MARCH 10, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463.
CERTAIN SPORT UTILITY VEHICLES EQUIPPED WITH AN AUTOMATIC TRANSMISSION, FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 102, "TRANSMISSION SHIFT LEVER SEQUENCE, STARTER INTERLOCK AND TRANSMISSION BRAKING EFFECT." UNDER CERTAIN VEHICLE STARTING CONDITIONS, THE SHIFT LEVER POSITION INDICATOR LOCATED IN THE INSTRUMENT PANEL CLUSTER MAY NOT ILLUMINATE. IF THE SHIFT LEVER POSITION INDICATOR DOES NOT ILLUMINATE, THE DRIVER MAY NOT KNOW WHICH GEAR THE VEHICLE IS IN.
Consequence & remedy
Consequence: THE VEHICLE MAY MOVE IN AN UNINTENDED DIRECTION RESULTING IN POSSIBLE INJURY TO OTHERS OUTSIDE OF THE VEHICLE.
Remedy: DEALERS WILL REPROGRAM THE INSTRUMENT PANEL CLUSTER FREE OF CHARGE. THE RECALL BEGAN ON FEBRUARY 14, 2005. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, AND GMC AT 1-866-996-9463.
CERTAIN TRUCKS, SPORT UTILITY VEHICLES, AND VANS EQUIPPED WITH BOSCH HYDRO-BOOST BRAKE ASSEMBLIES, THE HYDRAULIC BRAKE BOOSTER PRESSURE ACCUMULATOR MAY CRACK AND SEPARATE FROM THE HYDRO-BOOST ASSEMBLY DURING NORMAL OPERATING CONDITIONS.
Consequence & remedy
Consequence: IF A SEPARATION OCCURRED AND THE HOOD OF THE VEHICLE WERE OPEN, FRAGMENTS FROM THE ACCUMULATOR COULD CAUSE INJURY TO PEOPLE IN THE IMMEDIATE AREA. THE PRESENCE OF THIS CRACK OR FRACTURED SURFACE COULD ALLOW THE HYDRAULIC FLUID TO LEAK FROM THE ACCUMULATOR CIRCUIT OF THE BOOSTER ASSEMBLY. THE LOSS OF FLUID WOULD CAUSE INCREASED STEERING AND BRAKING EFFORT AND A CRASH MAY OCCUR WITHOUT PRIOR WARNING.
Remedy: DEALERS WILL TEST THE HYDRO-BOOST ASSEMBLY FOR FUNCTIONAL OPERATION OF THE TWO-FUNCTION VALVE. IF THE HYDRO-BOOST ASSEMBLY FAILS THE TEST, DEALERS WILL REPLACE THE ASSEMBLY FREE OF CHARGE. THE RECALL BEGAN ON MARCH 23, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC TRUCKS AT 1-866-996-9463 AND HUMMER AT 1-800-732-5493.
ON CERTAIN SPORT UTILITY VEHICLES AND PICKUP TRUCKS EQUIPPED WITH 5.3L (RPO L59) V8 ENGINES, THE ENGINE FUEL RAIL CROSSOVER TUBE RETAINER SCREWS WERE NOT MANUFACTURED TO SPECIFICATIONS AND MAY BREAK.
Consequence & remedy
Consequence: IF THE TUBE RETAINER SCREW BREAKS, FUEL COULD LEAK FROM THE FUEL RAIL CROSSOVER JOINT, THE ENGINE MAY STALL AND, IF AN IGNITION SOURCE WERE PRESENT, AN ENGINE COMPARTMENT FIRE COULD OCCUR.
Remedy: DEALERS WILL INSPECT THE FUEL RAIL CROSSOVER TUBE AND, IF NECESSARY, REPLACE THE RETAINER SCREWS. OWNERS WERE NOTIFIED BY TELEPHONE ON JULY 30, 2004, WITH A FOLLOWUP OWNER LETTER BEGAN AUGUST 5, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463. NOTE: THE GM BULLETIN LISTS THE TAHOE AND YUKON MODELS BECAUSE CANADIAN VEHICLES ARE INCLUDED IN THE BULLETIN. NO U.S. TAHOE OR YUKON VEHICLES ARE INCLUDED IN THE U.S. CAMPAIGN.
