SECOND CHEVY 04 THAT TRANSMISSION WENT IN MY FIRST WAS A TAHOE NOW MY AVALANCHE! ALL THIS MONEY INTO VEHICLES AND THEY DON'T LAST 50,000 MILES OR WITH MY TRUCK 75,000 WHAT IS WRONG WITH CHEVY TRANSMISSIONS? WE TRADED TAHOE IN FOR A SUBARU AND MY NEXT TRUCK WILL NOT BE A CHEVY EVEN THOUGH I HAVE ALOT OF MONEY ON MY GM CREDIT CARD TOWARDS A NEW VEHICLE! *TR

VEHICLE TRANSMISSION FAILED AT 73,500 MILES. VEHICLE JUST STOPPED IN MIDDLE OF HIGHWAY WHILE TRAVELING AT APPROX 45 MILES PER HOUR. SUBSEQUENT REBUILD BY MECHANIC REVEALED THAT GM HAD INSTALLED INCORRECT VALVE BODY GASKETS IN THE TRANSMISSION, LIKELY CONTRIBUTING TO THE PREMATURE FAILURE. *TR

TL*THE CONTACT OWNS 2004 CHEVROLET AVALANCHE. THE CONTACT WAS DRIVING 55 MPH WHEN THE RPMS INCREASED. THE CONTACT HAD DIFFICULTY SWITCHING GEARS AND THE VEHICLE LOST POWER. THE WINDSHIELD WIPERS WOULD NOT SHUT OFF UNLESS THE CONTACT RESTARTED THE VEHICLE. THE TRANSMISSION AND THE WATER PUMP FAILED COMPLETELY. THE DRIVER SIDE DOOR HANDLE BROKE AND THE CONTACT CANNOT GET OUT OF THE VEHICLE UNLESS SHE CLIMBS OVER THE PASSENGER SEAT. THE SPEEDOMETER ONLY DISPLAYED 10 AND 20 MPH WHENEVER IT WAS COLD OUTSIDE. THE FAILURE MILEAGE WAS 23,965 AND THE CURRENT MILEAGE WAS 97,323.

WHILE DRIVING ON FREEWAY VEHICLE WAS REVVING UP, IMMEDIATELY EXITED FREEWAY AND FOUND TRANSMISSION WAS GONE, VEHICLE WOULD NOT GO IN REVERSE, DID DRIVE IN NEUTRAL. VEHICLE HAS ONLY 30K MILES. TOOK VEHICLE TO TRANSMISSION MECHANIC STATED THE CHEVY AVALANCHE AND DENALI ARE KNOWN FOR THIS, AND FEELS THIS IS A FACTORY DEFECT. HIS VEHICLE TOO WENT OUT AT 20K MILES. MY COUSIN TRANSMISSION TOO WENT OUT AT 50K MILES, WOULD LIKE TO HAVE DEALER REPAIR MY VEHICLE. HOW MANY MORE VEHICLES DOES THE NHTSA NEED TO COMPLAIN ABOUT SO THE MATTER CAN BE CORRECTED BY THE DEALER(S) OR MANUFACTURE. *TR

I HAVE PROBLEM WITH THE BRAKE SYSTEM, AND THE TRANSMISSION FLUID CAME OUT FROM THE FROM FRONT PASSENGER SIDE. I TOOK IT TO THE CHEVY DEALER, BUT I WAS TOLD THAT THE TRANSMISSION CLUTCH WAS BURNED OUT, MAYBE IT AN DEFECTED TRANSMISSION OR RECALL, IM NOT SURE, BUT I DO KNOW THAT THE TRANSMISSION AND THE BRAKE SYSTEM ARE NOT IN SAFE CONDITIONS, NOR WORKABLE. NOT TO MENTION THE CRACKING NOISE IN THE FRONT OF THE SUSPENSION, WHILE TURNING. *TR

MAY 2006 ELECTRONIC SWITCH REPLACED BECAUSE 4 WHEEL DRIVE WAS ENGAGING WITHOUT BEING ACTIVATED. HAD BEEN TO DEALERSHIP SEVERAL TIMES WITH PROBLEM AND FINALLY HAD THEM ADMIT THERE WAS A PROBLEM. FEB 2008 FRONT WHEEL DRIVE HAD TO BE REPLACED AS IT WAS A POSSIBILITY THAT IT COULD LOCK UP WHILE DRIVING. OUT OF WARRANTY SO I HAD TO PAY $1,300.00 IN REPAIRS. CONTACTED GM EXEC OFFICES AND THEY INVESTIGATED ONLY TO ADVISE THEY COULD DO NOTHING BECAUSE THE CAR WARRANTY 35,000 MILES HAD EXPIRED AND CAR HAD 65,000 MILES ON IT. I THINK THE FRONT END DRIVE WAS DAMAGED WHEN THE SWITCH FAILED AND IT TOOK TIME FOR IT TO FAIL. *TR

Mileage: 65,000

TRANSMISSION OR OTHER ELECTRICAL DEVICE FAILED ALLOWING MY 2004 CHEVROLET AVALANCHE TO ROLL BACKWARDS INTO A LAKE. *TR

(1) 2005 CHEVROLET AVALANCHE 1500. 119,000 MILES, 95% INTERSTATE. VEHICLE DOES NOT TOW, GO OFF ROAD, OR ENGAGE IN OTHER ACTIVITIES WHICH WOULD INCREASE THE STRESS ON THE DRIVE TRAIN BEYOND NORMAL WEAR AND TEAR. TRANSMISSION HAS RECEIVED REGULAR MAINTENANCE PER THE MANUFACTURERS RECOMMENDATIONS. (2) PART FAILED DURING MERGE ONTO HIGHWAY FROM COMPLETE STOP. FAILURE RESULTED IN A POWER LOSS TO VEHICLE, MAKING ACCELERATION VERY DIFFICULT AND MAXIMIZING VEHICLE SPEED AT 35 MPH. TRAFFIC BEHIND VEHICLE HAD TO SIGNIFICANTLY SLOW DOWN TO AVOID ACCIDENT. (3) DEALER REPLACED TORQUE CONVERTER AND IMMEDIATELY SHIPPED PART OFF SITE BEFORE REQUEST FOR RETURNED PART. DEALER CLAIMS CUSTOMER ABUSE. *JB

MY HUSBAND, MY TWO CHILDREN AND I WERE ALL IN OUR 2004 CHEVROLET AVALANCHE K1500, HEADED TO CHURCH ON SUNDAY MORNING, GOING DOWN THE STREET WE LIVE ON. MY HUSBAND, WHO WAS DRIVING, TURNED ON THE CROSS STREET. ALL OF A SUDDEN, EVERY ONE HEARD A BIG CLUNK, LIKE SOME THING HAD DROPPED. THE CAR WOULD NOT MOVE FORWARD. MY HUSBAND DROVE OUR VEHICLE BACKWARDS ALL THE WAY HOME. IT WAS PARKED FOR A FEW WEEKS, WHILE WE CONTACTED AAA, THE MANUFACTURER, AND LOCAL CHEVY DEALERSHIPS TO FIND OUT ABOUT REPAIR AND WARRANTIES. WE BELIEVE THIS IS A FAILURE OF THE TRANSMISSION. THIS VEHICLE HAS ABOUT 39000 MILES, JUST OVER THE WRITTEN WARRANTY, WHICH IS 36000. THE MANUFACTURER HAS NOT YET OFFERED TO PAY FOR THE REPAIRS BUT ADVISED US TO TAKE IT IN TO THE CHEVY DEALERSHIP TO CONFIRM THE DIAGNOSTICS. THE VEHICLE IS CURRENTLY BE TESTED BY A CHEVROLET DEALERSHIP IN REDDING, CA. THE DEALERSHIP HAS CONTACTED THE MANUFACTURER TO FIND OUT WHAT THEY WILL DO TO REPAIR THE CONFIRMED "TRANSMISSION" PROBLEM. THIS IS AN EXPENSIVE REPAIR THAT HAS RESULTED IN OUR LOSS OF USE OF A VEHICLE THAT WAS WITHIN ITS NORMAL EXPECTED USE AND REPRESENTS A SUBSTANTIAL FINANCIAL BURDEN. I HAVE ALSO CONTACT THE FEDERAL TRADE COMMISSION. I WAS PLEASE TO KNOW THAT THE VEHICLE MAY STILL BE WITHIN ITS IMPLIED WARRANTY (FIRST FOUR YEARS) AND THE RIGHT TO REVOKE PURCHASE MAY BE AN OPTION IF THE MANUFACTURER AND DEALERSHIP REFUSE TO CORRECT THE PROBLEM AT NO COST TO US. I AM CONCERNED THAT THE PROBLEM, HOWEVER, MAY BE MORE WIDESPREAD, AND FELT I SHOULD REPORT THIS DEFECT OF THE CHEVROLET AVALANCHE 2004 K1500, FOR FURTHER INVESTIGATION IN CASE OTHER OWNERS HAVE THE SAME ISSUE. *JB

Mileage: 39,000

DT: THE CONTACT COMPLAINED ABOUT RACK AND PINION STEERING PROBLEM. THE VEHICLE CLANGED WHILE CHANGING GEARS. WHEN PUTTING PRESSURE ON THE ACCELERATOR PEDAL AND DRIVING BETWEEN 60 - 70 MPH HE COULD HEAR A WHINING SOUND. WHEN HE RELEASED THE ACCELERATOR PEDAL THE NOISE STOPPED. THE DEALERSHIP REPLACED THE DRIVESHAFT BUT, THIS DID NOT CORRECT THE PROBLEM. *AK

Mileage: 3,500

WHEN THE CONSUMER ATTEMPTED TO ACCELERATE FROM A STOP, THE VEHICLE HESITATED INTERMITTENTLY. *AK THE VEHICLE NEEDED A NEW ALTERNATOR, RADIO SYSTEM (CD WOULD OVER HEAT). *SC *JB

DURING ACCELERATION (TAKING FOOT OFF ACCLERATOR STOPS NOISE) A GRINDING NOISE APPEARS TO BE COMING FROM REAR AXLE OR TRANSMISSION. NOISE IS INTERMITTENT, OCCURS APPROXIMATELY 4-5 TIMES PER WEEK. HAVE NOT BEEN ABLE TO IDENTIFY UNIQUE CONDITIONS THAT CAUSE OCCURRENCE. NOISE WILL GENERALLY ONLY OCCUR FOR A SINGLE ACCELERATION AND AFTER IT GOES AWAY, IT IS UNKNOWN WHEN IT WILL RETURN.
