1ST COMPLAINT: AFTER PASSING A VEHICLE ON A HIGHWAY (THIS REQUIRED THE SUBURBAN TO GO INTO THE PASSING GEAR), THE SUBURBAN'S ELECTRICAL SYSTEM AND ENGINE AUTOMATICALLY SHUT DOWN RIGHT ON THE HIGHWAY. I WAS FORCED TO IMMEDIATELY PULL OVER IN ORDER TO AVOID BE HIT BY PASSING VEHICLE. AFTER WAITING APPROXIMATELY 5 MINUTES, THE SUBURBAN STARTED UP AGAIN. WE STARTED DRIVING AGAIN BUT AGAIN ONCE I TRIED TO ACCELERATE OR PASS ANOTHER VEHICLE THE SUBURBAN WOULD SHUT DOWN AGAIN. AUTO MECHANIC HAS NOT BEEN ABLE TO IDENTIFY WHAT CAUSES THE VEHICLE TO DO THIS. VERY FRUSTRATING AND DANGEROUS IF THIS HAPPENS ON A BUSY HIGHWAY OR FREEWAY. 2ND COMPLAINT: CLUSTER PANEL WENT HAYWIRE. SPEEDOMETER STOPPED WORKING, OIL GAUGE NOT READING PROPERLY ETC. EVENTUALLY, THE ENTIRE CLUSTER PANEL SHUT DOWN. HAD TO REPLACE IT AT A COST OF ABOUT $500. 3RD COMPLAINT: DRIVERS SEAT FUNCTIONS AND HEATING MECHANISIM MALFUNCTIONED. THE DRIVERS HEATED SEAT STOPPED WORKING AND THE SEAT CONTROLS MALFUNCTIONED. THE SOME OF THE DRIVERS SEAT CONTROLS STOPPED WORKING OR ARE REVERSED. EXAMPLE; WHEN YOU PUSH THE LEVER TO MOVE THE SEAT FORWARD IT GOES BACKWARD AND VIS VERSA. THE DRIVERS SIDE HEATED SEAT STOPPED WORKING AND IT WILL CANCEL OUT THE PASSENGERS SIDE HEATED SEAT. EXAMPLE; IF THE PASSENGER SIDE HEATED SEAT IS SELECTED, IT WORKS BUT ONCE YOU SELECT THE DRIVERS SIDE HEATED SEAT IT WILL CANCEL OUT THE PASSENGER SIDE AND THE DRIVERS SIDE STILL DOESN'T WORK. AUTO MECHANIC CLAIMED THE DRIVERS SIDE HEATED SEAT ELEMENT WAS BAD. HAD IT REPLACED AT A COST OF $300 BUT STILL DID NOT SOLVE THE PROBLEM. THE ORIGINAL HEATED SEAT ELEMENT WAS NOT BAD EITHER. *TR

DRIVING DOWN THE ROAD, WHEN ALL OF A SUDDEN "REDUCED ENGINE POWER". REPLACED THE THROTTLE BODY, PEDAL SENSOR, AND WIRING HARNESS WITHOUT ANY SUCCESS. GM WANTS 150 JUST TO PLUG IT INTO THEIR COMPUTER TO TELL ME WHAT I CAN GET DOWN FOR FREE WITH MY BUDDIES CODE READER....NO I WON'T LET MY WIFE OR CHILDREN DRIVE THE CAR. I ONLY DRIVE IT TO AND FROM WORK. HAD TO GO OUT AND BUY A TOYOTA JUST TO KEEP MY MIND AT EASE SO MY WIFE AND OR KIDS WON'T GET KILLED FROM THIS PROBLEM. IT SEEMS LIKE CHEVY/GMC DOESN'T CARE ABOUT THIS ISSUE UNTIL MULTIPLE PEOPLE DIE FROM THIS. I HOPE TO SEE THAT THEY WILL DO THE RIGHT THING. THINKING OF CONTACTING MY CONGRESS REPRESENTATIVE TO SEE WHAT THEY CAN DO TO HELP OUT US THAT ARE DEALING WITH THIS ISSUE. NOBODY ELSE IS. *TR

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.
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.
CERTAIN SPORT UTILITY VEHICLES, PICKUP TRUCKS, AND PASSENGER VANS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 135, ?PASSENGER CAR BRAKE SYSTEMS.? SOME OF THESE VEHICLES WERE PRODUCED WITH AN OUT-OF-SPECIFICATION BRAKE HYDRO-BOOST HOUSING RELIEF VALVE BORE.
Consequence & remedy
Consequence: CONSEQUENTLY, THE VALVE O-RING SEAL MAY FRACTURE. STEERING EFFORTS MAY BE SLIGHTLY INCREASED WHILE BRAKING OR PARKING. UNDER CERTAIN DRIVING CONDITIONS, A FRACTURED SEAL MAY REQUIRE A SLIGHT INCREASE IN THE APPLIED BRAKE PEDAL EFFORT TO ACHIEVE THE SAME VEHICLE DECELERATION RATE AS PRIOR TO THE SEAT FRACTURE.
Remedy: DEALERS ARE TO REPLACE THE HYDRO-BOOST RELIEF VALVE. THE RECALL BEGAN ON JUNE 18, 2004. OWNERS SHOULD CONTACT CADILLAC AT 1-866-982-2339; CHEVROLET AT 1-800-630-2438; GMC AT 1-866-996-9463; OR HUMMER AT 1-866-486-6376.
