I DROVE TO WORK & PARKED MY 2007 AVALANCHE IN MY EMPLOYERS TRUCK GARAGE AS I DO EVERY DAY. I WENT INTO THE OFFICE ATTENDED A JOB BRIEFING & WE PUT ON OUR COVERALLS FOR WORK THEN WE GOT READY TO LEAVE TO GO TO THE 1ST JOBSITE BUT AS SOON AS THE 1ST TWO COWORKERS WALKED OUT OF THE SHOP THEY TURNED AROUND YELLING THAT MY TRUCK WAS ON FIRE. I DIDN'T BELIEVE THEM AT 1ST BECAUSE I HAD JUST PARKED LIKE 15 MINUTES PRIOR. PARKED & NOT RUNNING. WELL I LOOKED AND MY WHOLE ENGINE COMPARTMENT WAS FULL OF FLAMES. WE USED 4 FIRE EXTINGUISHERS TO PUT THE FIRE OUT & THE FIRE DEPARTMENT ARRIVED TO FINISH. MY VEHICLE WAS TOTALLED & I ONLY HAD LIABILITY INSURANCE.

VEHICLE HAS 120,000 MILES ON IT AND HAS A RANDOM MISFIRE, WITH TRACTION CONTROL AND STABILTRACK WARNINGS AND A FLASHING CHECK ENGINE LIGHT. ENGINE HAS EXCESSIVE OIL CONSUMPTION AND RUNS ROUGH. INSTALLED NEW PLUGS AND WIRES, NO CHANGE. AFTER READING UP ON THESE ENGINES I FOUND OUT THAT THE AFM / DOD FEATURE IS A COMMON FAILURE FOR THESE ENGINES. GM SHOULD STEP UP AND HELP OWNERS WITH SOME OF THE REPAIR COSTS. THIS IS GOING TO BE EXPENSIVE. *TR

I HAVE BEEN TALKING TO OTHER PEOPLE ON CAR GURUS AND THERE ARE THOUSAND ON THAT SIGHT HAVING THE SAME PROBLEM WERE HAVING. AND THE SAD THING IS WE DONT HAVE THE MONEY TO HAVE OUR TRUCK TOWED INTO TOWN AND GET IT FIXED. BECASUE THEY TELLS US THAT THEY HAVE SO MANY PEOPLE HAVING THE SAME PROBLEM. I FEEL LIKE GM SHOULD DO A RECALL OR PEOPLE SHOULD BE ABLE TO DO A GROUP LAWSUIT TOWARD GM FOR SUCH A BIG DEAL LIKE THIS IS. AND ALSO OUR DASHES ARE ALL CRACKED DOWN THE MIDDLE. WHICH ON THAT SIGHT THERE ARE ALOT HAVING SAME ISSUE.

STABILITY CONTROL WARNING POPS UP ON DISPLAY, RESULTING IN A SEVERE POWER REDUCTION. THIS CAUSES THE VEHICLE SPEED TO DROP FROM 70 MPH TO AROUND 35MPH INSTANTLY.

I READ THAT THIS IS A VERY COMMON ISSUE WITH GM VEHICLES YET NOTHING IS BEING DONE BY GM TO PROVIDE A SAFETY RECALL

I BOUGHT THIS TRUCK NEW AND AT ABOUT 30000 MILES IT STARTS TO BURN OIL.ABOUT A QUART BETWEEN OIL CHANGES.TOOK TO DEALER AND THEY REPLACED LIFTERS.THERE WAS NO DIFFERENCE.THEN DID OIL CONSUMPTION TEST WHERE IT GOT TO THE POINT OF BURNING 1QUART OF OIL EVERY 800 MILES.TOOK BACK IN THEN WAS TOLD EXTENDED WARRANTY WILL NOT COVER AND IT IS NORMAL WEAR.TRUCK AT THAT TIME ONLY HAD 73000 MILES ON IT(AUG.2015).THEY TOLD ME IT COULD BE$3600 TO REPAIR THIS ISSUE.I THAN TOLD THEM NOT TO TOUCH IT AND STILL DEALING WITH ISSUE AT 78000 MILES.

THERE HAVE BEEN CONTINUAL PROBLEMS WITH THE ENGINE OF MY TRUCK AND I HAVE FOUND OUT SINCE BUYING IT THERE ARE SEVERE PROBLEMS WITH A LOT OF THE ENGINES OF THE 2007 AVALANCHE. THE MECHANIC TOLD ME WHEN WE BROUGHT THE TRUCK IN TO FIND OUT WHY THE ENGINE HAD A HESITATION IN IT, THAT WE SHOULD HOPE IT WAS THE EXHAUST SYSTEM SEALS NEEDING TO BE REPLACED THAT CAUSED THE HESITATION BECAUSE THE ONLY OTHER TIMES HE HAD SEEN THIS PROBLEM IT WAS A MANUFACTURING DEFECT IN THE 2007 GMC ENGINES THAT HE HAD SEEN THESE PROBLEMS WITH ALOT OF THE 2007 CHEVY AND GMC TRUCKS INCLUDING HIS OWN. WE ALSO ABOUT 2 MONTHS AFTER BUYING THE TRUCK NOTICED THAT THE TRUCK WAS GOING THROUGH OIL VERY QUICKLY BUT THE MECHANIC SAID THAT THE SEALS WEREN'T LEAKING SO DIDN'T KNOW WHY WE WERE BURNING OIL SO FAST. THE DASH HAS CRACKED AT THE CORNER OF THE AIR BAG AND IF THERE IS AN ACCIDENT IT COULD SEND SHARDS FLYING. THE DRIVERS DOOR STICKS AND THE STABILITY CONTROL GO'S IN AND OUT OF WORKING ORDER. THE ELECTRIC MIRRORS STOPPED FOLDING IN AND TILTING DOWN AND TRIED TO HAVE IT FIXED BUT CHEVROLET SAID THEY WOULDN'T GIVE THE MECHANIC THE CODE TO GET INTO THE COMPUTER SYSTEM TO FIX IT AND THE BACK UP SENSOR THAT HAD STOPPED WORKING ALSO. WE NOW HAVE TO GO TO A CHEVROLET DEALERSHIP TO HAVE IT FIXED. THERE HAVE BEEN SO MANY PROBLEMS WITH THESE TRUCKS THAT CHEVROLET HASN'T FIXED THESE TRUCKS EVEN USED USUALLY COST AT LEAST $15000 BRAND NEW YOU COULD DOUBLE OR TRIPLE THAT PRICE I DON'T THINK IT'S A LOT TO ASK TO HAVE A DECENT ENGINE THE OTHER PROBLEMS I COULD DEAL WITH BUT THE ENGINE PROBLEM THEY SHOULD FIX

THE ENGINE HAS A HESITATION DUE TO A MANUFACURING PROBLEM IT ALSO USES MORE OIL THAN IT SHOULD BETWEEN OIL CHANGES. ALSO HAVING PROBLEM WITH THE ELECTRICAL SYSTEM EVERY TIME I TURN AROUND SOMETHING STOPS WORKING LIKE THE SIDE MIRROR ON THE DRIVERS SIDE WON'T FOLD IN LIKE ITS SUPPOSED TO AND THE BACKUP SENSOR STOPPED WORKING. TRIED TO GET OUR MECHANIC TO FIX IT BUT IT NEEDS A CODE TO GET INTO THE ELECTRICAL SYSTEM AND GM WON'T GIVE IT TO ANYONE BUT THIER OWN MECHANICS. SO NOW WE HAVE TO GO TO THE DEALERSHIP TO HAVE IT FIX WHICH WILL COST ALOT MORE. ABOUT AMONTH AFTER PURCHASE THE DASH GOT A SMALL CRACK AROUND THE PASSENGER AIR BAG. THIS IS OUR SECOND 2007 AVALANCHE THE FIRST ONE HAD NO PROBLEMS AT ALL AND I HAD NO IDEA THAT THIS MODEL HAD SO MANY PROBLEMS THAT THE MANUFACTURER WON'T FIX. WITH AS MUCH AS THESE TRUCKS COST EVEN USED THE SHOULD HAVE TO REPAIR THINGS THAT ARE MANUFACTURER DEFECTS

TOTAL ENGINE LOSS AT HIGHWAY SPEED, CHEVROLET WANT TO REPLACE THE ENGINE, BUT AS I READ ALL THESE COMPLAINT ABOUT ENGINE AND OIL AND AFM. I BELIEVE THEY SHOULD BE HELD ACCOUNTABLE FOR SELLING LEMONS. THE NHTSA MUST PUT A END TO MANUFACTURERS SELLING TRASH. *TR

MY MAIN CONCERN IS THE FACT THAT THE VEHICLE BURNS EXCESSIVE AMOUNTS OF OIL. I HAVE LODGED ABOUT FIVE COMPLAINTS WITH OURISMAN ROCKMONT CHEVROLET AND MY CONCERNS REMAINED UNADRESSED. THEY DID, ON ONE OCCASION, CHANGE A GASKET COVER AND OIL PAN GASKET, BUT THE PROBLEM PERSISTED. FINALLY, I WAS RECENTLY TOLD THAT I NEEDED AN OIL DEFLECTOR PER A SERVICE BULLETIN AND WAS TOLD IT WOULD COST NEARLY $1,500.00. ALTHOUGH MY CONCERNS WERE ALL MADE DURING THE WARRANTY PERIOD, OURISMAN IS ATTEMPTING TO CHARGE ME NOW THAT MY VEHICLE IS OUTSIDE THE WARRANTY. I CONTACTED CHEVY CUSTOMER SERVICE BUT NO LUCK. *TR

THE ENGINE LIGHT COMES ON; ENGINE REDUCE POWER LIGHT, STABILIZER TRACT LIGHT COMES ON PLUS OIL LIGHT AND OTHER LIGHTS. I HAVE HAD IT IN THE SHOP TO TRY TO FIGURE OUT WHY MY AVALANCHE KEEPS BREAKING DOWN. AND I WAS TOLD THAT THEY CAN NOT FIND A PROBLEM. I WAS NEVER INFORMED THAT THEY HAVE HAD PROBEMS WITH THE WIRING. IN DECEMBER 2011 MY AVALANCHE SHUT ITSELF OFF DURING A SNOW STORM. EVENTUALLY, IT STARTED BUT BECAUSE OF REDUCED POWER IT WOULD ONLY GO BETWEEN 35-45 MILES PER HOUR. I MADE IT TO A REPAIR SHOP, THEY COULD NOT FIND A PROBLEM, BUT REPLACED SENSORS AND/OR RELAYS. IN JUNE 2012 THE LIGHTS CAME ON, I COULD ONLY GO APPROX 35-40 MILES PER HOUR. CALLED AND SET UP AN APPOINTMENT. ON THE WAY TO THE APPOINTMENT THE ENGINE OIL LIGHT CAME ON AND THE CAR SHUT DOWN. I HAD TO CALL FOR A TOW TRUCK. I TOOK IT TO A NON DEALER SERVICE REPAIR SHOP, BECAUSE THEY WERE THE CLOSEST. WHEN THEY LOOKED THE CAR OVER THE WIRES WERE EATEN. I WAS INFORMED THAT THE NEWER CARS HAVE A SOY BASE IN THEIR WIRING AND THAT THE RODENTS LOVE TO EAT THIS PRODUCT. WHY ARE THEY USING THIS SOY BASED WIRING? THIS IS NOT SAFE. I CAN NOT HAVE MY VEHICLE BREAK DOWN LEAVING ME STRANDED ON THE SIDE OF THE ROAD. IT IS GETTING VERY COSTLY WHEN PARTS ARE BEING REPLACED WHEN IT IS THE WIRING THAT IS FAULTY. I LIVE IN THE COUNTRY AND I CAN NOT KEEP THE MICE OUT OF MY TRUCK. PLEASE LOOK INTO WHY THE CAR MANUFACTURES ARE USING THIS PRODUCT WHICH IS CAUSING MAJOR SAFETY AND FINANCIAL CONCERNS WHY AREN'T THE MANUFACTURES INFORMING THE PUBLIC OF THIS PROBLEM. *TR
