2007 CHEVROLET SUBURBAN 1500 Engine And Engine Cooling Problems

LIKE TO PLACE A FORMAL COMPLAINT REGARDING THE OIL CONSUMPTION FOR 2007 CHEVY SUBURBAN AND THE HORRIBLE QUALITY OF VEHICLE. A FEW MONTHS AFTER PURCHASING THE VEHICLE THE TRANSMISSION GAVE OUT. I'VE BEEN HAVING PROBLEMS WITH OIL CONSUMPTION AND ITS HORRIBLE. I BELIEVE THAT CHEVY SHOULD STAND BEHIND THEIR PRODUCT AND DO A MASSIVE RECALLS FOR THESE VEHICLE. AGAIN, CHEVY SHOULD STAND BEHIND THEIR PRODUCT. THERE ARE SO MANY REVIEWS ABOUT THIS SAME PROBLEM. OBVIOUS THERE IS A PROBLEM. WILL NEVER BUY A CHEVY AGAIN NOR WILL I RECOMMEND CHEVY VEHICLES!! *TR

SINCE 2008 OUR SUBURBAN HAS REQUIRED OIL SERVICING ON AVERAGE EVERY 2 MONTHS. WE TOOK IT TO MANY DEALERS AND WAS TOLD WE NEEDED TO BE ABLE TO TRACK THE CONSUMPTION SOMEHOW. I STATED, CAN'T YOU CHECK WHEN THE OIL SERVICING LIGHT COMES ON AND WAS TOLD NO. DON'T KNOW WHY IT CONSUMES SO MUCH OIL AND IT'S NOT LEAKING. *TR

EXCESSIVE OIL CONSUMPTION - AT LEAST 1QT PER 1K MILES SOMETIMES MORE. CHEVY EVENTUALLY FIXED THIS UNDER WARRANTY AFTER PROVING OUT THE CONSUMPTION. CHEVY CORPORATE IS AWARE OF THIS PROBLEM IN THESE TRUCKS AND HAS NOT ONLY WRITTEN IT UP, BUT HAS DESIGNED A FIX FOR IT, DEALER STATES CHEVY CORP DECLINED TO ISSUE A RECALL BECAUSE IT'S A $1600 REPAIR. THE ISSUE IS TWO-FOLD. SOMETHING TO DO WITH THE VALVES NOT SEALING CORRECTLY AND OIL IN THE OIL PLAN SPLASHING UP ONTO THE CYLINDER WALLS FASTER THAN THE RINGS CAN REMOVE IT. WHEN MY VEHICLE WAS REPAIRED, THEY DID SOME WORK TO THE VALVE TRAIN, REPLACED FOULED SPARK PLUGS AND ADDED SOME TYPE OF BAFFLE TO THE OIL PAN. FIX IMPROVED POWER, FUEL CONSUMPTION AND REDUCED OIL CONSUMPTIONS TO NORMAL LEVELS. TRUCK NOW RUNS LIKE NEW. IF YOU ARE EXPERIENCING THIS GO TO CHEVY AND DEMAND THE FIX. YOU'LL NEED TO PROVE THE OIL CONSUMPTION EITHER THROUGH OIL CHANGE LOGS, OR AS I DID - WHICH WAS TO DO AN OIL CHANGE AT THE DEALER, HAVE THE OIL PLUGS SEALED BY THE DEALER, THEN DRIVE IT 6,000 MILES - HAVING THE DEALER REFILL THE OIL WHEN LOW TO TRACK CONSUMPTION. THEY WON'T WANT TO FIX THIS BECAUSE IT'S SO EXPENSIVE BUT DEMAND THE REPAIR UNDER THE WARRANTY. *TR

VEHICLE HAS EXCESSIVE OIL CONSUMPTION, USING MORE THAN 1 QUART OF OIL EVERY 2K MILES. I PURCHASED THE VEHICLE AT A GM DEALERSHIP WITH 67K MILES ON IT. THEY TOLD ME IT WAS JUST SERVICED, AND THE DIPSTICK SHOWED TO BE AT THE FULL LINE WITH CLEAN OIL. ABOUT 4K MILES LATER THE LOW ENGINE OIL LIGHT CAME ON. THE ENGINE OIL LIFE INDICATOR SAID IT HAD 49% LIFE LEFT. I CHECKED THE OIL LEVEL AND FOUND IT WAS MORE THAN 2 QUARTS LOW. I HAVE RESEARCHED THIS AND FOUND THAT GM IS EITHER UNABLE OR UNWILLING TO REPAIR. I WILL CONTACT THE SELLING DEALER FOR THE RECORD. *LN

I AM SEEING AN EXCESSIVE OIL CONSUMPTION ISSUE WITH MY 2007 CHEVY SUBURBAN. FROM MY MEASURE IT IS CONSUMING 4 1/2 QTS OF OIL PER 3000 MILES. THE DEALER ACKNOWLEDGED THAT THIS IS A "KNOWN" ISSUE BUT DIDN'T PERFORM ANY REPAIRS. I AM INSTEAD PERFORMING AN OIL CONSUMPTION TEST. THAT'S FINE BUT I NOW HAVE A FAMILY VEHICLE THAT I CANT TRUST FOR ANTICIPATION OF ENGINE FAILURE/LOCK UP OR WORSE ENGINE BURN UP OR FIRE FROM A LOW OIL CONDITION. *TR

ENGINE STARTED IDLING ROUGH AND THE 'ENGINE LIGHT' CAME ON AND STAYED ON.THEN THE NEXT DAY, WENT TO START CAR AND IT WAS REALLY IDLING ROUGH, SPUTTERING, THEN STABLITRAK LIGHT AND 'TRACTION CONTROL OFF' LIGHT AND ABS LIGHTS ALL CAME ON. THE CAR FELT LIKE IT WAS GOING TO DIE UNTIL ABOUT 20 MPH, THEN MADE A JERKING MOTION AND RAN FINE. THIS CONTINUED TO HAPPEN UNTIL I TOOK IT TO THE SHOP. THEY KEPT IT FOR A WEEK, REPLACED THE FUEL PUMP, BUT THIS DID NOT FIX THE PROBLEM. THE CAR STILL RUNS ROUGH AND THE LIGHTS STILL COME ON WHENEVER I HAVE TO IDLE, INTERSECTIONS, ETC... I HAVE BEEN READING AND I AM CONCERNED THAT THERE IS NO FIX FOR THIS PROBLEM. I BELIEVE IT IS A FAULTY ENGINE/ELECTRICAL ISSUE AND THERE NEEDS TO BE A RECALL. THIS IS COMPLETELY DANGEROUS, IF MY STABILITRAK SYSTEM GOES OFF AND I AM ON UNSTABLE GROUND, RAIN, SNOW, ETC... IT WILL CAUSE MY CAR TO BRAKE AND I WILL LOOSE CONTROL OF MY CAR. I AM WORRIED THAT IT IS GOING TO DIE IN AN INTERSECTION, SINCE IT HAS A HARD TIME COMING OUT OF AN IDLE WITH ANY POWER. *TR

IN OCT. 2007 I PURCHASED A BRAND NEW 2007 CHEVROLET SUBURBAN FROM GORDON CHEVROLET IN TAMPA FLORIDA, IT HAD 20 MILES ON IT. ON DECEMBER 9TH 2008 WHILE ON MY WAY HOME FROM WORK, AT APPROXIMATELY 12:45 AM, IT EXPLODED AND WAS ENGULFED IN FLAMES. I RECEIVED 2ND AND 3RD DEGREE BURNS AND WAITED ON THE SIDE OF THE ROAD FOR CLOSE TO 30 MINUTES FOR HELP TO ARRIVE. THE SUBURBAN HAD ABSOLUTELY NO AFTERMARKET CHANGES OR ANY TYPE OF MODIFICATIONS DONE TO IT. ALL OF ITS SERVICING AND REPAIR WORK WAS DONE AT COX CHEVROLET IN BRADENTON FLORIDA, A GENERAL MOTORS DEALERSHIP. THE TRUCK HAD JUST OVER 35,000 MILES ON IT AND IS NOW JUST A BURNT OUT SHELL. DURING THE 1 YEAR AND 2 MONTHS I OWNED IT, I HAD SEVERAL PROBLEMS WITH IT AND TOOK IT TO THE SERVICING DEALERSHIP FOR ALL THE PROBLEMS. MY ATTORNEY AND MY INSURANCE AGENT THINK IT WAS A DEFECT IN THE MANUFACTURING OR A DEFECT IN THE REPAIR. AN OFFICIAL CAUSE HAS YET TO BE DETERMINED AND BECAUSE OF GM'S GOING BANKRUPT THEY ARE NOT INTERESTED. *TR

TL*THE CONTACT OWNS A 2007 CHEVROLET SUBURBAN 2500. THE CONTACT TOOK HER VEHICLE TO THE DEALER BECAUSE IT WAS UNDERPOWERED. THE VEHICLE STALLED AT INTERSECTIONS AND WHILE MERGING INTO TRAFFIC AT 15 MPH. SHE HEARD STRANGE NOISES COMING FROM THE ENGINE COMPARTMENT. THE DEALER WAS UNABLE TO DIAGNOSE THE CAUSE OF FAILURE FOR FIVE WEEKS. CHEVROLET SENT A REPRESENTATIVE TO INSPECT THE FAILURE AND STATED THAT THE VEHICLE WAS DESIGNED TO DRIVE IN THAT MANNER. THE SERVICE MANAGER AND THE DEALER OWNER ACKNOWLEDGED THE FAILURE, BUT THE DISTRICT MANAGER WAS RELUCTANT AND INFORMED THE DEALER TO STOP REPAIRING THE VEHICLE. THE CONTACT DROVE THE VEHICLE BACK TO HER RESIDENCE WHERE IT CURRENTLY REMAINS. THE CURRENT MILEAGE WAS 3,000 AND FAILURE MILEAGE WAS 2,500.

DT*: THE CONTACT STATED WHILE DRIVING 20 MPH, THE CHECK ENGINE AND THE TRACTION CONTROL LIGHT ILLUMINATED CONSTANTLY. THE ENGINE THEN LOST THE MAJORITY OF POWER AND WOULD NOT ACCELERATE. THE VEHICLE WAS MOVED TO THE SIDE OF THE ROAD, AND WAS SHUT OFF. THE VEHICLE WAS RESTARTED AFTER 10 MINUTES AND DRIVEN TO A RESIDENCE. THE VEHICLE WAS TAKEN TO A SERVICE DEALER, WHO WAS UNABLE TO DETERMINE THE PROBLEM. THE MANUFACTURER WAS ALSO NOTIFIED.
