2007 GMC Canyon Engine Problems

TL* THE CONTACT CALLED ON BEHALF OF THE OWNER OF A 2007 GMC CANYON. WHILE DRIVING AT AN UNKNOWN SPEED, THE CONTACT BECAME NAUSEOUS. THE CONTACT PULLED THE VEHICLE OFF THE ROADWAY, EXITED THE VEHICLE, AND PASSED OUT FOR SEVERAL MINUTES ACCORDING TO A WITNESS. THE DRIVER EXPERIENCED SYMPTOMS DUE TO CARBON MONOXIDE POISONING. THE CONTACT ATTEMPTED TO MOVE THE VEHICLE ONCE SHE REGAINED CONSCIOUSNESS, BUT BECAME OVERWHELMED. THE CONTACT STOPPED THE VEHICLE AND, WHILE ATTEMPTING TO RETRIEVE DOCUMENTS FROM THE GLOVE BOX, SHE NOTICED FLAMES INSIDE THE GLOVE BOX. THE CONTACT EXITED THE VEHICLE. THE FIRE DEPARTMENT WAS NOTIFIED AND WAS ABLE TO EXTINGUISH THE FIRE; HOWEVER, THE VEHICLE WAS DESTROYED. A FIRE REPORT WAS NOT FILED. THE DRIVER WAS TRANSPORTED BY AMBULANCE TO A NEARBY HOSPITAL. THE DRIVER RECEIVED OXYGEN FOR SIX HOURS TO REMOVE THE CARBON MONOXIDE FROM HER LUNGS. THE VEHICLE WAS TOWED TO A PRIVATE LOT. THE DEALER AND MANUFACTURER WERE NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 85,003.

THE VEHICLE HAS 9 BOLTS HOLDING THE EXHAUST MANIFOLD TO THE ENGINE. THE OWNER SMELLED STRONG EXHAUST SMELL IN THE CABIN. HE REMOVED THE EXHAUST MANIFOLD FROM VEHICLE AND FOUND THAT 4 OF THE 9 BOLTS HAD FAILED AND WERE BROKEN OFF FLUSH WITH THE ENGINE BLOCK. THERE WAS EXHAUST RESIDUE IN THE IMMEDIATE AREA OF THE 1ST AND 5TH CYLINDER PORT INDICATING THAT EXHAUST GAS WAS BEING DISCHARGED INTO THE ENGINE BAY. THE FAILURE IS AN ALARMING SAFETY EVENT BECAUSE OF THE POTENTIAL FOR HOT EXHAUST TO CAUSE A FIRE IN THE ENGINE COMPARTMENT AND THE POTENTIAL FOR ASPHYXIATION DUE TO CONTAMINATED CABIN AIR. THIS IS ALSO AN ENVIRONMENTAL CONTROL FAILURE BECAUSE A PORTION OF THE EXHAUST GAS ISS BYPASSING THE CATALYTIC CONVERTERS. THE OWNER IS THE ORIGINAL OWNER AND ALL EQUIPMENT IS ORIGINAL. HE IS A DEGREED MECHANICAL ENGINEER AND HAS WORKED IN AUTOMOTIVE COMPONENT MANUFACTURING. GM WAS CONTACTED DIRECTLY AND THE OWNER DIRECTED TO SEE THE DEALERSHIP. THE OWNER PROVIDED THE DEALERSHIP WITH THE ATTACHED PHOTOS BUT THEN REFUSED TO INSPECT THE VECHICLE WITHOUT FIRST COLLECTING A "DIAGNOSTIC FEE." THE OWNER REFUSED.

MY 2007 GMC CANYON IS SUFFERING FROM THE PROBLEMS DESCRIBED IN SERVICE BULLETIN #07123A, ENGINE INTAKE VALVE SEAT/MISFIRE. THE EXTENDED WARRANTY GRANTED TO THOSE IN #07123A WAS FOR MODEL YEARS 2004-2006. MY VEHICLE WAS BUILT AFTER THIS TIME FRAME BUT IS EVIDENCE THAT THE PROBLEM STILL EXISTS. GM SHOULD DO THE RIGHT THING AND EXTEND THE SERVICE BULLETIN TO INCLUDE MODEL YEAR 2007. THE VEHICLE HAS 48,864 MILES ON IT AND I WAS QUOTED $2,500 PLUS TAX TO MAKE THE REPAIRS AT BROTHERTON GMC/CADILLAC IN RENTON, WA. *TR

OVER FUSED DASH WIRING, CAUSING CONNECTORS TO MELT AND RESISTORS TO BLOW IN A/C AND HEAT FAN CONTROL SYSTEM ON A TRUCK WITH ONLY 10,000 MILES ! CAUSING A SOURCE FOR FIRE AND TOXIC GAS IN CABIN! THIS REQUIRED A CONNECTOR AND A RESISTOR TO BE REPLACED, AT A COST OF $306.13, BUT GMC DID NOT LOWER THE FUSED RATING IN TRUCK. *TR
