2001 Chevrolet Suburban Engine

EXHAUST AND MANIFOLD COVER BOLTS ARE TOO WEAK AND THE HEADS BREAK OFF. I HAD TO REPLACE ALL OF THEM WITH RACING BOLTS. MUCH BETTER NOW.

TL* THE CONTACT OWNED A 2001 CHEVROLET SUBURBAN. WHILE DRIVING THE VEHICLE, SMOKE EMITTED UNDER THE HOOD OF THE VEHICLE. THE CONTACT COASTED THE VEHICLE TO THE SIDE OF THE ROAD AND EXITED THE VEHICLE. THE VEHICLE CAUGHT ON FIRE, WHICH WAS EXTINGUISHED BY THE FIRE DEPARTMENT. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED AND DESTROYED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 200,000. THE VIN WAS NOT AVAILABLE.

WHEN VEHICLE IS IDLING WHILE NOT MOVING EXTREME AMOUNTS OF EXHAUST FUMES ARE ENTERING THE CABIN AREA THROUGH THE VENTILATION SYSTEM. THIS IS DUE TO DEFECTIVE EXHAUST MANIFOLD BOLTS WHICH ARE BREAKING ALLOWING THE EXHAUST MANIFOLD TO OPEN AND ALLOW FUMES TO ENTER THE ENGINE COMPARTMENT WHICH RESULTS IN THE EXHAUST FUMES ENTERING THE PASSENGER CABIN AREA THROUGH THE VENTILATION SYSTEM. THIS IS A HEALTH ISSUE FOR PASSENGERS INSIDE THE CABIN BREATHING THE TOXIC EXHAUST FUMES. THIS SHOULD BE A SAFETY RECALL ON GM TO FIX THE PROBLEM DUE TO POOR ENGINEERING DESIGN AND FOR USING POOR QUALITY COMPONENTS WHICH FAIL FOR NO REASON. ALSO THIS IS AN EXTREMELY DANGEROUS SITUATION FOR PASSENGERS INSIDE THE VEHICLE, WHICH HAVE TO BREATH THE DANGEROUS EXHAUST FUMES. GM SHOULD BE MADE TO REPAIR ALL VEHICLES AFFECTED BY THIS PROBLEM WHICH WERE DESIGNED AND ENGINEERED WITH INFERIOR PARTS WHICH ARE CAUSING THIS DANGEROUS SITUATION FOR MILLIONS OF PEOPLE ACROSS THIS COUNTRY.

I HAVE A 2001 CHEVY SUBURBAN THAT COMPLETELY STALLED OUT, (SEPT 29,2011) WHEN I WAS GETTING READY TO TRANSPORT MY FOUR YOUNG CHILDREN TO SCHOOL. PLEASE NOTE, THAT I'M IN AN AREA THAT IS NOT ACCESSIBLE BY PUBLIC TRANSPORTATION. THIS MEANS THAT WHEN MY CAR IS DOWN, I'M AT THE MERCY OF FRIENDS AND NEIGHBORS WHICH IS QUITE AN INCONVENIENCE. I HIRED A SERVICE GUY TO DIAGNOSE THE PROBLEM AND HE SAID IT WAS A PROBLEM WITH THE CRANKSHAFT. WHILE ORDERING THE PART, HE WAS NOTIFIED THAT THE PART WAS ON A RECALL LIST. I CHECKED THE WEBSITE NHTSA.GOV TO VERIFY AND THE RECALL #07V521000 DID EXIST. I CONTACTED THE CHEVY DEALER (NASH CHEVROLET) IN SNELLVILLE AND WAS TOLD THAT MY VIN# WAS NOT IN THE BATCH AND IF THEY SERVICED IT, THE COST WOULD BE $2500. I CONTACTED THE MANUFACTURER AND WAS TOLD THAT MY PROBLEM COULD BE ATTRIBUTED TO WEAR AND TEAR. I WOULD LIKE TO KNOW IF THERE IS ANY POSSIBILITY TO GET THE DEALER TO REPAIR MY CAR AND IF IT'S POSSIBLE TO HAVE THE INVESTIGATION REOPENED AND THE SCOPE ADJUSTED TO INCLUDE ALL 2001 SUBURBANS THAT ARE NONCONFORMING. I WOULD LIKE TO ALSO KNOW, HOW DOES GM/CHEVY DETERMINE WHICH CUSTOMERS DESERVE TO BE SAFE ON THE ROAD, AND WHY WEREN'T ALL THEIR QUALIFYING CONSUMERS NOTIFIED. IS GM ABOVE THE LAW? HOW IS IT THAT GM IS NOT ALLOWED TO COMPLY TO THESE FEDERAL LAWS AFTER AN INVESTIGATION HAS BEEN CONDUCTED? DOES GM ONLY RESPOND TO THEIR CUSTOMERS IF THEIR IS DEATH AND DISMEMBERMENT OR IF LITIGATION IS INVOLVED? PLEASE ADVISE. *TR

THE FAILURE AND CURRENT MILEAGE WAS UNKNOWN.

PER NHTSA CAMPAIGN ID#07V521000, THE 2001 CHEVROLET SUBURBAN 2500 IS SUBJECT TO THIS RECALL BY GM. I HAVE EXPERIENCED THE SAME DESCRIBED PROBLEM OF VEHICLE ENGINE STALLING AND NOT OPERATIVE WHILE TRAVELING ON THE ROAD. I HAVE CONTACTED BOTH GM AND GM'S LOCAL AUTHORIZED DEALERSHIP IN CONCORD, CALIFORNIA. BOTH REFUSED TO HONOR THIS RECALL. PLEASE HELP BEFORE AN ACCIDENT OCCURRED. THANK YOU. *TR

BEGINNING IN AUGUST 2009 MY 01 CHEVY SUBURBAN WOULD STALL WHILE I WAS DRIVING. AFTER THE FIRST TIME, A NEW BATTERY WAS INSTALLED. THIS HAPPENED 2 MORE TIMES FROM MID AUGUST 09 TO 9/15/09 AT WHICH TIME WE BROUGHT THE TRUCK IN FOR SERVICE. THE DEALER WAS UNABLE TO DUPLICATE THE PROBLEM AND WE BROUGHT THE TRUCK HOME. ABOUT A WEEK LATER, IT HAPPENED AGAIN AND THEN 3 MORE TIMES BETWEEN 9/15 AND 10/15/09. DURING THIS PERIOD WE FOUND A RECALL NOTICE (GM RECALL NO. 06083) FOR A CRANKSHAFT SENSOR COVERING 2001 SUBURBANS, BUT NOT MY PARTICULAR VEHICLE. THE RECALL DETAILED THE EXACT PROBLEM I WAS HAVING. THE TRUCK WAS BROUGHT INTO THE DEALER ON 10/15/09 AND I INSISTED THAT THE CRANKSHAFT SENSOR BE REPLACED. TO DATE, THERE HAVE BEEN NO FURTHER PROBLEMS WITH THE VEHICLE AND I BELIEVE THAT THE CRANKSHAFT SENSOR WAS THE CAUSE OF THE STALLING. *TR

TL* THE CONTACT OWNS A 2001 CHEVROLET SUBURBAN 2500. WHILE DRIVING THE VEHICLE WILL INTERMITTENTLY STALL WITHOUT ANY PRIOR WARNINGS. AN INDEPENDENT DIAGNOSTIC TEST WAS PERFORMED; AND THE CRANKSHAFT POSITION SENSOR CODE WAS DISCOVERED. THE MANUFACTURER WAS CONTACTED IN REFERENCE TO RECALL# 07V521000( ENGINE AND ENGINE COOLING).

THE CURRENT MILEAGE WAS 92,000 AND FAILURE MILEAGE WAS 70,000.

THE CHECK ENGINE LIGHT CAME ON, ON MY 2001 SUBURBAN AT 29,000 MILES. THIS WAS MY DADS VEHICLE AND WAS GARAGE KEPT AND DRIVEN ON TRIPS OR TO CHURCH IN RURAL TEXAS, WHICH IS WHY AFTER 8 YEARS IT ONLY HAD 29,000 MILES. I HAD IT SCANNED AT AUTO ZONE. A #1 CYLINDER MISFIRE WAS DETECTED. I MOVED THE COIL, SPARK PLUG, AND WIRE TO OTHER CYLINDERS TO ISOLATE THE PROBLEM. THE SCAN STILL DETECTED #1 CYLINDER MISFIRE EVEN AFTER DRIVING OVER 50 MILES. THE MISFIRE WAS NOT DETECTABLE BY THE WAY THE TRUCK WAS RUNNING. I WENT AHEAD AND REPLACED THE INJECTOR ON THAT CYLINDER JUST TO RULE IT OUT. ONCE AGAIN AFTER OVER 50 MILES OF DRIVING IT STILL SCANNED AS A #1 CYLINDER MISFIRE. I HAD PLANNED ON TAKING IT TO THE DEALER ON MONDAY, AUGUST 24, 2009. ON SATURDAY, AUGUST 22, 2009 MY WIFE AND DAUGHTER WERE ON THEIR WAY BACK TO THE HOUSE AND THE TRUCK DIED DRIVING DOWN THE FREEWAY. THEY WERE ABLE TO RESTART IT AND LIMP HOME. I FOUND NO COMPRESSION ON THE #1 CYLINDER AND TOOK OFF THE ROCKER ARM COVER TO FIND A BROKEN SPRING ON THE EXHAUST VALVE. HAD IT ONLY BEEN 3 YEARS OLD IT WOULD HAVE BEEN UNDER WARRANTY. THIS SEEMS TO BE A BAD SPRING BAD LUCK STORY. I WAS CURIOUS TO KNOW IF OTHERS ENCOUNTERED THE SAME PROBLEM OR DID THE BLACK CLOUD JUST DWELL OVER ME. SINCE I CAN REPAIR IT MYSELF I AM. THIS PROBLEM MIGHT HAVE HAPPENED TO OTHERS WITHOUT THEIR KNOWLEDGE SINCE THEY HAD IT REPAIRED BY THE DEALER. THE COST TO ME FOR PARTS IS ABOUT $350. THE GREATEST COST WAS GASKETS. REPAIR AT A DEALER WOULD BE BETWEEN $1500 AND $5000 I'M SURE (THERE WAS A BENT VALVE I REPLACED, AND A MARK ON THE PISTON I AM LEAVING ALONE, I'M NOT SURE THEY WOULD REPAIR JUST WHAT WAS NEEDED OR GO FURTHER). IT IS DISHEARTENING WHEN SOMETHING THAT SHOULD NOT HAPPEN DOES. THERE IS MORE I WOULD LIKE TO VENT HERE BUT THAT IS NOT THE PURPOSE OF MY COMPLAINT. I JUST WANTED THE COMPLAINT REGISTERED SOMEWHERE. THANKS. *TR

I HAVE A 2001 SUBURBAN 2500 8.1 L. 3/4 TON. THE ENGINE WOULD STALL WHILE DRIVING WITHOUT WARNING. IT HAS HAPPENED MANY TIMES INCLUDING IN THE MIDDLE OF AN INTERSECTION AND ON THE FREEWAY GOING AT FREEWAY SPEEDS INCLUDING HAULING A TRAILER. WHEN THIS OCCURS POWER STEERING AND POWER BRAKES ARE LOST WITH HOPES OF BEING ABLE TO COAST TO THE SIDE OF THE ROAD WITHOUT GETTING HIT. FOUND NHTSA RECALL # 07V521000 AND GM # 06083. THIS RECALL DESCRIBED MY VEHICLES PROBLEM EXACTLY. TOOK VEHICLE INTO DEALERSHIP MENTIONING RECALL, OUR VIN # IS NOT AFFECTED. DIAGNOSTIC SHOWED CRANKSHAFT POSITION SENSOR FAILURE EXACTLY LIKE THE RECALL. GM WOULD NOT COVER ANY EXPENSES BECAUSE VIN WAS NOT INCLUDED IN RECALL. AFTER REVIEWING OTHER COMPLAINTS, I SEE THAT THERE ARE OTHERS WHO HAVE HAD THE SAME ISSUE AND VIN #'S WERE EXCLUDED FROM THE RECALL. THIS RECALL SHOULD BE EXPANDED TO INCLUDED A WIDER RANGE OF VIN #'S OR AT LEAST INVESTIGATED FURTHER. TOO MUCH OF A COINCIDENCE AND TOO DANGEROUS OF A SITUATION TO LET THIS GO. *TR

CAR STALLED SUDDENLY AT 40 MPH, LOSING POWER STEERING IN TRAFFIC. AFTER A FEW MINUTES THE CAR RESTARTED. INTERMITTENTLY STALLS. WHILE GM HAS RECALLED 2001 SUBURBANS FOR CRANK POSITION FAILURES IN THIS YEAR MODEL, MY PARTICULAR VIN NUMBER WAS NOT COVERED BY THE RECALL. I PURCHASED REPLACEMENT PART AND CORRECTED THE PROBLEM. GM REFUSED TO REIMBURSE. VERY DANGEROUS SITUATION. NO WONDER GM IS IN DECLINE WITH THE LACK OF RESPONSE TO A VERY STRANGE AND DANGEROUS ENGINE STALL WITH ABSOLUTELY NO WARNING. *TR

TL*THE CONTACT OWNS A 2001 CHEVROLET SUBURBAN 2500. WHILE DRIVING 50 MPH, THE VEHICLE SHUT OFF WITHOUT WARNING. THERE WERE NO INDICATORS ILLUMINATED ON THE INSTRUMENT PANEL. THE CONTACT PULLED OFF THE ROAD, TURNED OFF THE VEHICLE, AND WAITED 30 SECONDS BEFORE RESTARTING THE VEHICLE. ONCE IT WAS RESTARTED, THE VEHICLE PERFORMED NORMALLY. THE VIN WAS EXCLUDED FROM NHTSA CAMPAIGN ID NUMBER 07V521000 (ENGINE AND ENGINE COOLING), IN WHICH THE CRANKSHAFT POSITION SENSOR COULD OPERATE OR FAIL COMPLETELY. THE FAILURES WERE IDENTICAL TO THOSE MENTIONED IN THE RECALL AND THE CONTACT WOULD BE RESPONSIBLE FOR THE REPAIR COSTS. THE FAILURE MILEAGE WAS 68,000 AND CURRENT MILEAGE WAS 72,500. UPDATED 12/16/08 *CN UPDATED 12/19/08.*JB

TL*THE CONTACT OWNS A 2001 CHEVROLET SUBURBAN. WHILE DRIVING 55 MPH, THE ENGINE COMPLETELY SHUT OFF. THE ENTIRE VEHICLE LOST POWER.

THE CURRENT AND FAILURE MILEAGES WERE 116,000.

BOUGHT A USED 01 SUBURBAN ON 9/10/06 IT HAS 826000 MILES ON IT. THE DAY AFTER I BOUGHT IT DRIVING DOWN THE ROAD 30 MPH, THE TRUCK STALLED. I PUT IT IN NEUTRAL, STILL ROLLING AND ATTEMPTED TO RESTART 2 OR 3 TIMES. IT FINALLY STARTED. IT HAS ALSO DONE IT AT A DEAD STOP AT THE BANK DRIVE THROUGH. THIS TIME IT DIDN'T RESTART UNTIL I PULLED THE KEY AND REINSERTED IT AND IT STARTED. AS OF TODAY 9/19/06 IT HAS DONE IT AT LEAST 7 TIMES. I TOOK IT TO CHEVROLET THEY SAID POSSIBLE CRANK POSITION SENSOR? *NM

VEHICLE WOULD DIE RANDOMLY WHILE OPERATING CAUSING LOSS OF STEERING AND BRAKING. USUALLY OCCURRED AT LOW SPEEDS (LIKE IN TRAFFIC) AND RE-STARTING REQUIRED LENGTHY CRANKING. THIS IS THE SECOND TIME THIS PROBLEM HAS COME UP WHILE I'VE OWNED THE VEHICLE WITH THE SAME CORRECTION, REPLACING THE CRANK POSITION SENSOR. I HAVE THE OLD PART. *JB
