2006 Chevrolet Avalanche 1500 Problems

Brake lines rusted out. Apparently this is an issue for this year and many other model year vehicles. Considering the brakes stop the vehicle, this is a big safety issue, and very expensive to be fixed.

POOR QUALITY BRAKE LINES HAVE CORRODED MAKING THE BRAKE SYSTEM FAIL HARD BRAKING, HAD LINE RUPTURE DUE TO CORROSION, NEAR COLLISION DUE TO BRAKE FAILURE

After purchasing my vehicle through a bank loan, the frame started to deteriorate resulting in suspension components to come loose and fall off. Lastly, rear driveshaft broke off, leaving me inoperable.

The vehicle was sold with significant rust damage to the underbody of the truck. The truck parts are rusted to a point the suspension, and axel are about to fall out. The truck is leaking gasoline due to the amount of rust. The power steering that they fixed after one day driving it had issues when sold is still having issues leaking fluid. It has been deemed unsafe to drive on road. The dealership sold the vehicle in unsafe conditions, and will not rectify the situation. I have documentation, and photos of the damage to the vehicle.

THE AIRBAG INDICATOR LIGHT IS ON AND OFF. TOOK IT TO SERIVE CENTERS THE LIGHT CAME OFF FOR A WEEK THEN CAME BACK AGAIN. MECHANIC TOLD ME THE SPRING COUL NEEDS TO BE REPLACED GOT IT REPLACED BUT THE PROBLEM IS STILL THE SAME. WHEN ITHE WEATHER IS COLD THE LIGHTS COMES OFF WHEN ITS WARM THE LIGHTS ARE ONE TOLD THE MECHANICS THEY SAID ITS THE CONNECTION THEY TRIED TO FIX LIGHT WILL COME OF FOR A FEW DAYS THEN BACK AGAIN. THE SECOND PROBLEM IS THE ENGINE LIGHT - THEY TOLD ME ITS THE FUEL EJECTION PUMP GOT IT REPLACED BUT NOT RESOLVED. I KEEP TAKING TTHE TRUCK BACK TO THE SERVICE CENTERS BUT AFTER A WEEK THE LIGHT INDICATORS ARE ON. I ALSO FAILED MY INSPECTIONS DUE TO THIS PROBLEM. THE ONLY REASON I PASS IS THAT IT HAS TO BE FIXED BUT AFTER INSPECTION THE LIGHTS ARE ON AGAIN. I HAVE READ ALL COMPLAINTS ABOUT THIS PROBLEMS BUT GMC MOTORS DOESN'T HAVE AN ACTIVE RECALL FOR IT ITS JUST A COMMUNICATION STATING THE PROBLEM. THE TRUCK IS STILL RUNNING BUT THIS SAFETY ISSUE NEEDS TO BE RESOLVED BY THE COMPANY. AND I THINK THATS PART OF THE REASON TGEY DONT MAKE THE AVALANCE ANYMORE.

AIR BAGS WARING LIGHT ON.

REAR BRAKE LINES BURST WHILE I WAS IN MOTION. I WAS GOING DOWN THE HIGHWAY AND HAD TO USE THE GEARS TO SLOW DOWN. THEY WERE CORRODED THROUGH. SAME THING HAPPENED IN 2016 WITH MY FUEL PUMP LINE CORRODED THROUGH. WAS LEAKING WHILE I WAS DRIVING. DID NOT NOTICE FOR A FEW DAYS UNTIL THERE WAS PUDDLES OF GAS WHERE I PARK. OVER THE PAST FEW YEARS MY CLADDING HAS BEEN FALLING OFF FROM RUST THROUGH ON THE BOTTOM SECURE POINTS.

TL* THE CONTACT OWNS A 2006 CHEVROLET AVALANCHE. THE CONTACT STATED THAT WHILE STARTING THE IGNITION, A STRONG BURNING ODOR EMITTED INSIDE OF THE VEHICLE. THE CONTACT NOTICED THAT THE HEATER BLOWER WIRE HARNESS AND RESISTOR MELTED. THE CONTACT REPLACED THE RESISTOR PERSONALLY BUT THE FAILURE PERSISTED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 150,000.

MY "SERVICE AIR BAG" LIGHT HAS STEADILY BEEN ON FOR A FEW WEEKS, CHECKED THE FUSE, CHECKED BASIC CONNECTORS (NO LOOSE WIRES). HAVE BEEN DOING INTERNET RESEARCH & FOUND MANY FORUM DISCUSSIONS ON THIS TOPIC DATING BACK TO 2003! I SEARCHED THIS SITE & FOUND THAT THERE HAS BEEN NO RECALL RELATED TO THIS ISSUE. CONSIDERING ONCE THIS "SERVICE" LIGHT IS ON, THE AIRBAGS WILL NOT WORK IN THE EVENT OF A CRASH, WHY HASN'T THERE BEEN A RECALL?? I AM DEFINITELY NOT EXCITED ABOUT GOING TO THE DEALER TO SEE WHAT THEY'RE GONNA CHARGE TO LOOK AT THE ISSUE & THEN FIND OUT WHAT THEY WILL CHARGE TO REPAIR THE ISSUE, ALTHOUGH MANY OWNERS HAVE RETURNED TO THEIR DEALERS MULTIPLE TIMES FOR THE SAME "FIX". THIS SHOULD BE FREE OF CHARGE TO DIAGNOSIS & REPAIR CONSIDERING IT IS A MAJOR SAFETY ISSUE! *TR

I WAS RECENTLY INVOLVED IN AN ACCIDENT WHERE I PASSED OUT WHILE OPERATING MY VEHICLE. I BELIEVE THAT CARBON MONOXIDE POISONING WAS THE CONTRIBUTING FACTOR THAT CAUSED THIS ACCIDENT. FAULTY EXHAUST MANIFOLD FASTENERS SEEMS TO BE AN ISSUE THAT COULD HAVE CAUSED THIS ACCIDENT. I WAS SHOCKED TO SEE THAT THERE IS NO RECALL FOR THIS PROBLEM. I HAVE INCURRED NUMEROUS PERSONAL EXPENSES DUE TO THE ACCIDENT, BUT FEEL LUCKY THAT THERE WERE NO SERIOUS INJURIES OR FATALITIES. I AM WRITING THIS TO CALL ATTENTION TO THE ISSUE IN HOPES THAT YOU WILL DO SOMETHING TO KEEP THIS FROM HAPPENING TO SOMEONE ELSE WHO MIGHT NOT BE AWARE OF THE ISSUE. I AM DISAPPOINTED THAT THERE HAS BEEN NO RECALL ON THIS PRODUCT. THE VEHICLE IS TOTALED, BUT COULD STILL BE EXAMINED TO FIND THE CAUSE.

VEHICLE HIT A TREE AND AIRBAGS DID NOT DEPLOY.

2006 CHEVROLET AVALANCHE 1500 4WD IN 2WD HI, DRIVING AT 55 MPH WITH TRANSMISSION IN D, ENGINE REVVED FREELY AS IF TRANSMISSION IN NEUTRAL. COASTED TO A STOP ONTO SHOULDER, SHIFTED INTO PARK, RELEASED FOOT BRAKE, VEHICLE BEGAN TO ROLL FORWARD (DOWNHILL), APPARENTLY BECAUSE TRANSFER CASE SHIFTED INTO NEUTRAL. SES INDICATOR NOT ON. TURNED OFF ENGINE. NO CODES (HAD CODE READER IN GLOVE BOX). TURNED ENGINE ON, SHIFTED TRANSMISSION INTO D AND FELT TRANSMISSION ENGAGE (APPARENTLY, TRANSFER CASE HAD ENGAGED FROM NEUTRAL). ACCELERATED GRADUALLY AND DROVE DOWN HIGHWAY FOR 1/4 MILE AND WHEN ACCELERATOR PEDAL WAS RELEASED, TRANSFER CASE SHIFTED INTO NEUTRAL, AGAIN, ENGINE REVVING FREELY WITH TRANSMISSION STILL IN D. COASTED TO A STOP ON SHOULDER, PRESSED 4WD HI AND FELT TRANSFER CASE ENGAGE, PRESSED 2WD HI AND FELT TRANSFER CASE DISENGAGE BUT NOW IN 2WD HI INSTEAD OF NEUTRAL. ACCELERATED GRADUALLY AND DROVE DOWN HIGHWAY AND WHEN ACCELERATOR PEDAL WAS RELEASED, TRANSFER CASE SHIFTED INTO NEUTRAL, AGAIN, ENGINE REVVING FREELY WITH TRANSMISSION STILL IN D. COASTED TO A STOP ON SHOULDER, AND REPEATED ABOVE SEQUENCE ON TRANSFER CASE TO SHIFT INTO 2WD HI. SHIFTED TRANSMISSION INTO 3, ACCELERATED GRADUALLY AND DROVE DOWN HIGHWAY, TRANSFER CASE REMAINED IN 2WD HI. SLOWED DOWN TO A STOP ON SHOULDER, TURNED OFF ENGINE, RESTARTED ENGINE AND SHIFTED TRANSMISSION INTO D, ACCELERATED GRADUALLY AND DROVE DOWN HIGHWAY AND WHEN ACCELERATOR PEDAL WAS RELEASED, TRANSFER CASE SHIFTED INTO NEUTRAL ONCE AGAIN. AFTER COASTING TO A STOP, REPEATED SEQUENCE TO ENGAGE TRANSFER CASE INTO 2WD HI, SHIFTED TRANSMISSION INTO 3 AND DROVE VEHICLE TO MECHANIC. STILL DIAGNOSING ISSUE. *TR

DRIVING HOME LAST NIGHT, I LOST 3RD AND 4TH GEARS IN MY TRANSMISSION UNDER NORMAL ACCELERATION. I HAVE AN '06 CHEVROLET AVALANCHE Z71 WITH LESS THAN 89,600 MILES ON IT. I HAVE NEVER TOWED ANYTHING EXCEPT FOR A UHAUL TRAILER ONCE FOR ABOUT 250 MILES. I WAS ON THE HIGHWAY WHEN THIS HAPPENED, TRAVELING 50-55 MPH WHEN IT OCCURRED. I WAS ABLE TO COAST TO A STOP ON THE SHOULDER OF THE HIGHWAY WITHOUT FURTHER INCIDENT, HOWEVER I WAS ALMOST REARENDED BY FOLLOWING TRAFFIC THE MOMENT IT HAPPENED BECAUSE OF THE SUDDEN DECREASE OF SPEED WITHOUT WARNING. THE TRANSMISSION GAVE NO WARNING BEFORE IT BROKE. I STILL HAD 1ST AND 2ND GEARS AS WELL AS REVERSE. I HAVE SPOKEN WITH A MECHANIC AND HE ESTIMATES REPAIR COSTS TO BE AROUND $3000. I HAVE CHECKED SEVERAL FORUMS FOR PEOPLE WHO HAVE EXPERIENCED SIMILAR PROBLEMS AND HAVE FOUND THAT THIS IS A "COMMON" PROBLEM HAPPENING TO AVALANCHES THAT ARE 2-6 YEARS OLD AND HAVING AS FEW AS 14,000 MILES ON THEM. MY TRUCK IS OUT OF WARRANTY, BUT THIS IS A PERVASIVE PROBLEM THAT HAS EXISTED SINCE 2002 ACCORDING TO OTHER AVALANCHE OWNERS. THE FORUMS I FOUND THE INFORMATION ON ARE; CHEVYAVALANCHEFANCLUB.COM, AVOWNERS.COM, AND CHEVYAVALANCHE.COM. THIS IS MORE THAN AN ISOLATED INCIDENT, HAVING HAPPENED TO MANY PEOPLE WHO OWN AVALANCHE'S AS EVIDENCED ON THE FORUMS. THIS DEFECT IS KNOWN BY GM AS EVIDENCED BY THERE OWN TECHNICAL SERVICE BULLETIN NUMBER "08-07-30-027 JUNE 08 A/T - NO MOVEMENT IN DRIVE OR 3RD GEAR". IT IS A FLAWED DESIGN OR FLAWED PARTS ARE BEING USED. GM SHOULD RECALL ALL AFFECTED TRUCKS WITH THIS PARTICULAR TRANSMISSION AND TAKE CORRECTIVE ACTION BEFORE SOMEONE IS FATALLY INJURED DUE TO A FAILURE ON A CONGESTED HIGHWAY. AN INVESTIGATIVE LOOK AT GM'S REPAIR RECORDS TO SEE HOW MANY TRUCKS HAVE BEEN IN FOR REPAIRS, THAT HAVE EXPERIENCED THE SAME OR SIMILAR FAILURES, WOULD PROBABLY WARRANT A FEDERAL INVESTIGATION INTO THE SAFETY OF THIS PRODUCT, AND WHETHER GM SHOULD BE COMPELLED TO INSTITUTE A RECALL. *TR

DRIVING DOWN THE ROAD THE TRUCK ENGINE WILL BE RUNNING WITH NO ABNORMAL SOUNDS, SMELLS, LEAKS BUT WILL ACT AS IF NOT IN GEAR. RPM'S WILL REV BUT TRUCK WILL NOT MOVE. ONLY AFTER PUTTING TRUCK IN PARK (LOTS OF GRINDING NOISES) THEN PRESSING THE 4WHEEL BUTTON THEN BACK TO 2WHEEL (SOMETIMES THROUGH TWO CYCLES) THE TRUCK WILL BACK INTO GEAR AND OPERATE PROPERLY. TOOK IT TO A TRANSMISSION SHOP PUT IT ON THE DIAGNOSTIC MACHINE AND NO ERROR CODES WERE GIVEN TO GIVE REASON WHY THE TRANSFER CASE DISENGAGES RANDOMLY. REPLACED THE TRANSFER SWITCH PER SHOP RECOMMENDATION "JUST IN CASE"IT WAS OKAY FOR ABOUT A MONTH THEN ONCE AGAIN ISSUES STARTED AGAIN JUST THE SAME AS BEFORE.

I BACKED OUT OF MY DRIVEWAY STOPPED MY TRUCK LIKE ALWAYS PUT IT IN D TO DRIVE HEARD A LOUD CLUNK NOISE AND NOW I HAVE 1 AND 2 GEAR ONLY TO USE THE TRUCK WAS STATIONARY WAS ON A MAIN ROAD I CHANGED THE TRANSMISSION FLUID SCREENS FILTERS EVERYTHING FLUSHED IT OUT AND STILL THE SAME THING A LOT OF PEOPLE ARE SAYING IT'S THE SPRAG UNIT I HAVE NO IDEA WHAT THAT IS I HAVE ONLY HAULED A FEW THINGS WITH IT WHEN WE WERE MOVING WE ONLY MOVED EIGHT MILES DOWN THE ROAD USED A TRAILER AND THE TOW GEAR THAT IS ON THE TRUCK. ALSO ABOUT A MONTH BEFORE THIS HAPPENED THE STABILITY SYSTEM LIGHT CAME ON AND SAID DISABLED BUT HAS NOT DONE IT SINCE ALSO MY TRUCK IS VERY CLEAN ALWAYS SERVICED ACCORDING TO THE MANUAL AND IS IN VERY VERY GOOD CONDITION

HEATED SEAT COMES ON BY ITSELF ALL THE TIME. IT HAS BURNED MY FATHER'S REAR END. I CHECKED IT OUT AND IT CAME ON 12 TIMES IN 5 MINUTES. MY FATHER IS OLDER AND DID NOT REALIZE HE WAS BURNING UNTIL IT WAS TOO LATE. I WAS TOLD BY THREE DIFFERENT DEALERS THAT THERE ARE NO SAFETY RECALLS FOR THIS. UPON READING HELP FORUMS, I DISCOVERED THEY DO HAVE A RECALL. I AM WAITING FOR A RESPONSE BEFORE I TAKE ANY FURTHER ACTIONS. THANK YOU

TL*THE CONTACT OWNS A 2006 CHEVROLET AVALANCHE 1500. THE VEHICLE HAD FIRESTONE WILDERNESS LE TIRES WHEN THE VEHICLE WAS PURCHASED.. THE VEHICLE WAS TAKEN TO THE DEALER TO HAVE THE TIRES ROTATED. AFTER THE ROTATION, WHILE DRIVING APPROXIMATELY 40-50 MPH, THE CONTACT HEARD A THUMPING SOUND COMING FROM THE VEHICLE. THE VEHICLE WAS DRIVEN BACK TO THE DEALER AND THE FAILURE WAS REPAIRED. SHE WAS NEVER VERBALLY INFORMED OF THE CAUSE OF THE FAILURE; HOWEVER, THE INVOICE STATED THAT THE TIRE WEAR WAS CAUSED BY THE ALIGNMENT.
