2006 CHEVROLET TRAILBLAZER Power Train Problems

Several months ago, I was at a fast food drive up window. I had my drivers side window down while paying for my food and receiving my food. It was down pouring and the inside of my door got pretty wet. I wiped off the rain as best as I could but everything was soaked. The very next day the drivers side door controls started to go haywire. The window button stopped working and my door locks only worked occasionally until they stopped working all together. My side mirrors can no longer be adjusted from the drivers seat. I have to get out of the vehicle and manually adjust both driver and passenger side mirrors. I'm not sure if there is a short in the wiring from the rain or just what is going on. I asked a parts dealer to see how much it would cost to replace the...

WHEN DRIVING YOU CAN ONLY GO UP TO 30 MILES AN HOUR, AND RPMS GO VERY HIGH AND VEHICLE DOES NOT GO ANYWHERE.

I PURCHASED THE VEHICLE FROM USADOS AUTO SALES AND THE OWNER TOLD ME THE CAR HAD 185,000 ON IT. WELL AFTER PAYING CASH AND WAITING 27 DAYS I FINALLY RECEIVE THE TITLE AND IT SAYS IT HAS 260,000. THE BILL OF SALE HE SIGNED WHEN HE BOUGHT IT ALSO STATED THAT THE ACTUAL MILEAGE WASN'T CORRECT. HE FILED MY BILL OF SALE OUT AND DIDN'T INFORM ME OR EVEN RIGHT BACK THERE FORM HE LIED TO ME AND SAID IT WAS 185,000 SO I CONTACTED HIM AND HE SAID IT WAS SOMETHING HE OVERLOOKED TO JUST WRITE ON MY BILL OF SALE THE ACTUAL MILEAGE AND I TOLD HIM NO I WOULD YOU HAVE SPENT $2500 ON A VEHICLE WITH 260,000 MILES AND HE REFUSES TO HELP ME. NOW THE VEHICLES CHECK ENGINE LIGHT IS ON. IT LEAKING OIL AND THE RADIO DOESN'T WORK AND IT KEEPS BLOWING FUSES.

WHEN TURN THE CAR OFF AND REMOVE THE KEY FROM THE IGNITION, THERE ARE TWO SPEAKERS THAT CONTINUE TO MAKE STATIC NOISE, WHETHER I HAVE OPENED THE DOOR OR NOT. IF I BUMP OR HIT THE CENTER CONSOLE IT WILL MAKE THE SPEAKERS LOUDER OR TURN OFF. THE CHECK ENGINE LIGHT IS ON FOR MULTIPLE CODES, AND I HAVE WORN OUT SHOCKS. THE SHOCKS SHOULD MAKE ME FEEL AS IF I AM GLIDING, BUR I FEEL AND JERK TO EVERY BUMP.

WHETHER THE CAR IS TURNED ON, OR OFF WITH OR WITHOUT KEY IN THE IGNITION, IT HAS A SMALL SPEAKER OR TWEETER THAT STEADILY STAYS MAKING A FAINT BUZZ. THE CENTER CONSOLE IS VERY LOOSE, AND IF YOU PRESS OR KNOCK UP AGAINST THE RIGHT SIDE OR THE BACK SIDE, IT BECOMES LOUDER AND/OR QUIETER. THEN WHILE IN AUTO (2WD-4WD^OR4WDL) AND DRIVING, THE TRANSMISSIONS FEELS TO NOT SWITCH GEER AT THE RIGHT TIME, OR FROM DRIVE TO REVERSE AND BACK TO DRIVE IT JOLTS FORWARD OR BACK REALLY HARD.

TL* THE CONTACT OWNS A 2006 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE FUEL, OIL AND SPEEDOMETER GAUGE FAILED TO PROVIDE AN ACCURATE READING. THE CONTACT ALSO STATED THAT THE TRANSMISSION FAILED. THE VEHICLE WAS NOT TAKEN TO A DEALER OR AN INDEPENDENT MECHANIC FOR A DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 241,539. THE VIN WAS NOT AVAILABLE.

HEAD LAMPS GO OFF AT NIGHT WHILE DRIVING WON'T COME BACK ON , STABILITRACK SHUTS OFF AN WARNING BELLS GO OFF FOR NO REASON. NOW OUT OF THE BLUE TRANSMISSION WILL NOT WORK. ONLY HAS 1ST AND 2ND, WHILE DRIVING ON ANY ROAD IN TOWN OR ON. HIGHWAY.

2006 CHEVROLET TRAILBLAZER. CONSUMER WRITES IN REGARDS TO TRANSMISSION ISSUES, ELECTRICAL SYSTEM ISSUES, DRIVER SEAT PROBLEMS AND OTHER VEHICLE ISSUES. *SMD *TR

THERE IS A DEFECT WITH THE VEHICLES ELECTRONIC CONTROL MODULE. THIS IS NOT SOMETHING THAT THE CONSUMERS ARE CAUSING, THIS DEFECT CAUSES THE VEHICLE TO SHUT OFF AT RANDOM TIMES, AND WILL NOT START BACK UP FOR SEVERAL MINUTES. THIS IS EXTREMELY DANGEROUS. I HAVE SEARCHED HUNDREDS OF FORUMS ON A FIX FOR THIS ONLY TO FIND HUNDREDS OF THOUSAND OF PEOPLE THAT ARE DEALING WITH THE SAME THING. CHEVY NEEDS TO STEP UP AND TAKE RESPONSIBILITY FOR THIS! I AM SURE THERE HAVE BEEN LIVES LOST BECAUSE OF THE VEHICLES SHUTTING OFF ON BUSY HIGHWAYS, AND STREETS. WHEN THIS HAPPENS YOU ARE A SITTING DUCK, AND HAVE TO WAIT TILL THE VEHICLE DECIDES IT WANTS TO START BACK UP. THIS HAPPENS WHILE DRIVING ON THE HIGHWAY, OR CITY ROADS. AT RANDOM INTERVALS. IT IS EXTREMELY DANGEROUS, AND I AM AMAZED THAT THERE HAS NOT BEEN A RECALL FOR THIS....

THE FRONT DRIVE AXLE THAT GOES THROUGH THE OIL PAN HOUSING BECAME OFF BALANCED, AND THE VIBRATIONS CAUSED SEQUENTIAL BREAKDOWNS THROUGH ALL OF THE CONNECTING PARTS DURING NORMAL USE, SUCH AS THE OIL PAN AXLE SEALS, FRONT DIFFERENTIAL SEALS, FRONT DIFFERENTIAL INTERNAL GEARS, CV JOINTS, WHEEL SEALS, AND THE CORRESPONDING FRONT AXLE SYSTEMS. WHEN THE WHEEL SEAL VIBRATED LOOSE, THE GEAR LUBE SPRAYED OVER THE ENGINE BLOCK, AND CAUGHT ON FIRE. THE VEHICLE WAS TOWED TO THE SHOP. THE MECHANIC PREDICTS THAT THE OFFENDING OFF-BALANCED AXLE MAY LOCK UP WHILE DRIVING IF NOT REPLACED. NOTE: THE DATE LISTED IS THE DATE OF THE FIRE IN THE ENGINE COMPARTMENT, BUT THERE ARE MANY ONGOING ISSUES WITH ALL OF THE PARTS LISTED, ESPECIALLY THE INTERNAL DISINTEGRATION OF THE FRONT DIFFERENTIAL.

VEHICLE SHUT OFF WHILE DRIVING ON HIGHWAY LOST POWER ALMOST GOT INTO ACCIDENT AND WAS BLOCKING TRAFFICC. OTHER VEHICLES LIKE MINE HAVE THE SAME PROBLEM.

MY WIFE WAS DRIVING OUR 2006 CHEVY TRAILBLAZER, AND WITHOUT ANY NOTICE WHILE IN DRIVE IT STOP ACCELERATING. ALL THE GEARS WERE AFFECTED (D,R,1,2,3 ) WE TURNED OFF THE VEHICLE, TURNED IT BACK ON AND THE VEHICLE DROVE FOR A FEW MILES AND THEN AGAIN WITHOUT NOTICE DID THE SAME THING.

DRIVING ALONG AT 30 MPH AND STEPPED ON GAS TO SPEED UP TO 45 MPH WHICH WAS THE NEW SPEED LIMIT, WHEN TRIED TO ACCELERATE I HAD NOTHING. IT WAS LIKE THE TRANSMISSION WAS IN NEUTRAL. I HAVE NO R/D/D3/D2/D1, NOT EVEN IN 4WD. THE TRANSMISSION IS GONE. I WAS COMING HOME FROM A 40 MILE TRIP, THERE WAS NO WARNING OF ANY PROBLEMS AT ALL. IT RAN FINE THE WHOLE TRIP AND THE NOTHING. THX

4WD SWITCH NO LONGER LIT UP TO SHOW WHAT IT WAS IN (4 OPTIONS: 2WD, AUTO, 4H, 4L). CONTROL MODULE CHANGED AND NOW STABILITY CONTROL IS PERMANENTLY LIT UP AS WELL AS ORIGINAL PROBLEM EXISTS. OTHER THAN TO CONTINUE TO CHANGE PART AFTER PART AFTER PART AND SINK THOUSANDS OF DOLLARS INTO AN UNDIAGNOSIBLE PROBLEM THERE DOESN'T SEEM TO BE AN ANSWER. MEANTIME THE VEHICLE IS UNSAFE TO DRIVE. *TR

4WD DISENGAGES AND BECOMES 2WD ONLY 4WD WILL NOT REENGAGE. *TR

HARD SHIFTING FROM 1ST TO 2ND GEAR ALL THE TIME! *TR

MY WIFE WAS COMING HOME FROM WORK. SHE STARTED HER CAR AND BACKED UP, WENT TO SHIFT TO DRIVE AND SOMETHING BROKE STRANDING HE IN A EMPTY PARKING LOT ON A SATURDAY. SHE WAS IN A TRAFFIC LANE AND BLOCKING THE HANDICAP PARKING SPACE. I HAVE OWNED CARS FOR MANY YEARS AND NEVER HAD SUCH A THING HAPPEN. WHY DID YOU MAKE AN ALL STEEL CABLE AND MOUNTINGS AND THEN PUT A TINY PLASTIC END ON IT THAT BRAKES ALL THE TIME. THE PARTS HOUSE AND THE SERVICE SHOPS ALL SAID IT HAPPENS ALL THE TIME AND YOU MUST BUY A REPLACEMENT FROM THE DEALER. THEY KNOW IT IS A PROBLEM AS THEY MUST STOCK THE CABLE ASSEMBLIES THAT COST A LOT TO CHANGE. PLEASE REDESIGN THEM AND CHANGE THE PLASTIC END TO A STAINLESS STEEL END AND RETROFIT ALL CARS, SUV'S AND TRUCKS THAT USE THIS PART. *TR

TRANSMISSION / SUN SHIELD FAILURE: LEAVING WORK, I PULLED OUT OF THE PARKING LOT ONTO A MAJOR ROAD. I ACCELERATED TO APPROXIMATELY 35-40 MPH AND HEARD A TREMENDOUS LOUD NOISE UNDERNEATH MY CAR AND THE CAR STARTED TO DECELERATE ON IT'S OWN. I IMMEDIATELY THOUGHT I RAN OVER SOMETHING MADE OF STEEL THAT WAS IN THE ROADWAY, BUT THERE WAS NOTHING THERE. I WAS BARELY ABLE TO PULL OFF THE ROAD BECAUSE, ALTHOUGH THE CAR WAS RUNNING, THE CAR WOULD NOT MOVE FORWARD. I CALLED A MECHANIC FRIEND WHO ADVISED ME THAT 2 OF THE 4 GEARS ARE WORKING. IT IS A TRANSMISSION PROBLEM. AFTER RESEARCHING ONLINE I SEE THAT THERE IS A SUN SHIELD / SUN SHELL PROBLEM WITH THESE TRAILBLAZERS (AND ENVOYS, ETC) AND I REALLY THINK THIS ISSUE SHOULD BE INVESTIGATED FOR A RECALL. IF I HAD BEEN ON A MAJOR HIGHWAY, I AM AFRAID OF WHAT...

THIS SUV IS NOTHING SHORT OF A ROLLING HAZARD. THE "CHECK ENGINE" LIGHT IS ON AND OFF, AGAIN, FOR THE PAST 6 DAYS. TRIED TO START IT UP THIS MORNING AND THE ENGINE LIGHT WAS ON. AS SOON AS I WAS ABOUT TO BACK OUT OF THE DRIVEWAY, THE VEHICLE STARTED TO IDLE IN A MANNER THAT CAUSED THE RPMS TO CRANK WAY UP AND THEN PLUNGE UNTIL ALMOST SHUTTING THE ENGINE DOWN WITH VIOLENT SHAKING AND LOUD ROARING NOISE. YESTERDAY, THE STABILITRAK WARNINGS (2) CAME ON THE DASHBOARD - I WAS ONLY GOING 3 MPH EXITING A PARKING LOT. THERE WAS NO INCLEMENT WEATHER AND THE ROAD WAS BONE DRY. I HAVEN'T BEEN ABLE TO PICK UP POWER AND IT SEEMS LIKE THE MORE I PRESS ON THE GAS PEDAL, THE SLOWER I GO. I LIVE IN HOUSTON AND THE TRAFFIC CONDITIONS REALLY DON'T ALLOW FOR A "SUDDEN STOP"...

CHANGING OUT THE AIR FILTER AS PART OF ROUTINE SELF CHECK AND MAINTENANCE. DECIDED TO CHECK THE OIL AND OTHER FLUIDS AT THE SAME TIME. THE OIL RESERVOIR IS BONE DRY. MY OIL IS CHANGED AT REGULAR INTERVALS, AT THE SAME SHOP, SINCE I'VE OWNED IT. THE OIL LIGHT/SENSOR DIDN'T COME ON. THE ONSTAR REPORT DOESN'T SHOW ANY LOW OIL LEVEL. MAYBE THIS IS A BUILT IN FEATURE FROM CHEVROLET - THE "THROW A ROD IN THE ENGINE INDUCTION SYSTEM"!!! VEHICLE IS ALWAYS SERVICED AT THE DEALER, BUT THEY USUALLY DON'T FIND ANYTHING WORTH FIXING UNTIL YOU BILL CAN COME OUT TO AT LEAST $1000. THE TV COMMERCIALS THEY RUN ABOUT CHEVY TRUCKS ARE "LIKE A ROCK" ARE VERY TRUE. THIS TRAILBLAZER IS AS USELESS AS A ROCK. *TR

TL* THE CONTACT OWNS A 2006 CHEVROLET TRAILBLAZER. THE CONTACT STATED WHILE DRIVING 10 MPH, HE DEPRESSED THE ACCELERATOR PEDAL TO INCREASE SPEED BUT THE VEHICLE WOULD NOT CHANGE GEARS. THE CONTACT THEN STOPPED THE VEHICLE, SHIFTED THE GEARS UNTIL THE VEHICLE MOVED IN REVERSE. THE CONTACT PLACED THE VEHICLE BACK IN DRIVE GEAR AND THE VEHICLE FUNCTIONED NORMALLY. THE VEHICLE WAS NEVER REPAIRED NOR WAS THE FAILURE DIAGNOSED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 33,000. THE CURRENT MILEAGE WAS 51,490.

MY SON AND I WERE OUT TODAY SHOPPING LOCALLY ONLY ABOUT 1 MILE FROM OUR HOME. THE CAR WAS FINE AND EVERYTHING WAS GREAT UNTIL ALL OF A SUDDEN, THE ACCELERATION ON THE CAR STARTED TO DECLINE EVEN THOUGH I HAD MY FOOT ON THE GAS THE CAR JUST SEEMED TO DO NOTHING. I WAS IN THE MIDDLE LANE AND TRAFFIC WAS VICIOUS, I TURNED ON MY HAZARDS AND ATTEMPTED TO TRY AND PUSH ON THE GAS. I CAR CAME TO A STOP BUT THE ENGINE WAS STILL RUNNING, IT FELT LIKE I WAS IN NEUTRAL BUT I WAS CLEARLY IN DRIVE. I CONTACTED ONSTAR THEY CALLED THE POLICE TO MAKE SURE WE DID NOT GET IN AN ACCIDENT, AS I STATED EARLIER, WE WERE IN TRAFFIC. I RECEIVED A PUSH TO A SAFE SIDE OF THE STREET AND TRIED TO RESTART THE CAR OVER AND OVER AGAIN, THE CAR...

TL* THE CONTACT OWNS A 2006 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT HE NOTICED FLUID LEAKING FROM THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR DIAGNOSIS. AFTER DIAGNOSIS, HE WAS INFORMED THAT THE TRANSMISSION COOLANT LINES HAD BECOME CORRODED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED FOR THE TRANSMISSION COOLANT LINES. THE MANUFACTURER WAS CONTACTED AND THEY ADVISED THAT THERE WERE NO RECALLS FOR HIS VEHICLE. THE FAILURE AND CURRENT MILEAGES WERE APPROXIMATELY 120,000.

THIS HAS HAPPENED TO ME 4 TIMES IN THE LAST YEAR AND A HALF FIRST TIME AT A RED LIGHT IT TURNED GREEN I WAS THE ONLY CAR AT THE LIGHT WHEN I HIT THE GAS IT FELT LIKE SOMEONE REAR ENDED ME LOOK NO ONE BEHIND ME THEN THE REAR BRAKES WERE LOCKED UP I DROVE IT 1/4 OF A MILE AND THEY UNLOCKED THEM SELVES I DROVE TO MY DEALER TOLD THEM HE LOOKED IT UP SAID THERE WAS A SERVICE BULLETIN ABOUT THAT TOOK MY BLAZER IN FOR A OIL CHANGE AN I SUPPOSED LOOKED AT THE BRAKES THEN ABOUT 6 MONTHS LATER THE SAME THING AND IT FELT LIKE SOME ONE REAR ENDED ME AGAIN BUT NO ONE THERE BEHIND ME..THEN ABOUT A MONTH AGO IN JULY THE SAME THING AT A RED LITE AND I HAD 3 SENIOR CITIZENS IN THE BLAZER WHEN THEY ALL...

TRANSMISSION COOLER LINES CORRODED THROUGH AND STARTED LEAKING. *TR

VERY HARD, SHOCKING 2-1 (MAYBE 3-2?) DOWNSHIFT AFTER LONG DRIVE AS IN 2-3 HOURS OR UNDER HEAVY LOAD. SUCH A HARD BRUTAL SHIFT CAN LEAD TO AN ACCIDENT. THIS IS A VERY SERIOUS SITUATION AND IT FEELS LIKE YOU HAVE HIT SOMETHING SOLID LIKE ANOTHER CAR. IT IS HARD ENOUGH TO COMPLETELY JAR OCCUPANTS AND DISLODGE GLASSES OFF OF YOUR FACE. YOU IMMEDIATELY LOSE ABOUT 5 MPH. FEELS LIKE IT COULD CAUSE COMPLETE TRANSMISSION FAILURE. IT IS VERY DIFFICULT TO RECREATE THIS FAILURE AND IT IS SO SCARY THAT YOU WOULD NOT WANT TO DO IT AGAIN. *JS

WITHOUT WARNING CAR WOULD NOT ACCELERATE WHEN APPLYING PRESSURE TO GAS PEDAL, THE MOTOR WOULD JUST REV UP. I HAD TO SHIFT AUTOMATIC TRANSMISSION INTO LOWER GEAR TO GET IT TO GO. I WAS ABLE TO DRIVE TO DEALERSHIP BY MANUALLY SHIFTING TRANSMISSION. SERVICE DEPARTMENT INFORM ME THAT TRANSMISSION WAS SHOT AND WOULD NEED TO BE REPLACED FOR ABOUT $3,000.00 DOLLARS. MY 2006 CHEVY TRAILBLAZER HAS ALWAYS BEEN SERVICE AT THE SAME DEALERSHIP AND ONLY HAS 28,783 MILES ON THE ODOMETER; I DID NOT THINK THAT THE TRANSMISSION WOULD FAIL WITH SUCH LOW MILEAGE. GM DID SAY THAT THEY WOULD COVER THE PARTS BUT I WOULD BE RESPONSIBLE TO PAY FOR LABOR. I REALIZED THAT CHEVY DID NOT OFFER 100,000 MILE POWER TRAIN WARRANTIES ON TRAILBLAZERS UNTIL 2007 BUT I BELIEVE THAT THE TRANSMISSION WAS DEFECTIVE FROM THE START AND CHEVY SHOULD BE RESPONSIBLE TO COVER REPLACEMENT COST. *TR

THE RPM GAUGE STOPPED WORKING TODAY. THE CAR HESITATED AND IS ACTING NOT RIGHT. I HAVE READ OF NUMEROUS PEOPLE HAVING THE EXACT SAME ISSUE. GM NEEDS TO DO A FULL RECALL ON THIS ISSUE. *TR

THE 2006 TRAILBLAZER HAD ISSUES WITH THE 2-WHEEL DRIVE/4-WHEEL DRIVE ACTUATOR AND SENSOR. I HAD THE SENSOR REPLACE UNDER WARRANTY BECAUSE THE INDICATOR LIGHT ON THE ACTUATOR HANDLE WAS IN A DIFFERENT RANGE THAN WHAT THE KNOB INDICATED. AFTER REPLACEMENT, THE TRUCK INDICATOR LIGHT WOULD OCCASIONALLY CHANGE WHILE DRIVING. THERE WERE NO WARNING LIGHTS INDICATING THAT THERE WAS AN ISSUE WITH THE POWER TRAIN SYSTEM. THE TRANSFER CASE EVENTUALLY BURNED UP DUE TO CONTINUOUS SWITCHING BETWEEN HIGH AND LOW HEARS WHILE DRIVING. THE TRUCK LOST POWER WHILE DRIVING AT 65 MILES AN HOUR IN MOUNTAINOUS AND SNOWY CONDITIONS. THE TRANSFER CASE, AND SENSOR AND ACTUATOR WERE ALL PAID MY THE CAR OWNER. *TR

2006 CHEVY TRAILBLAZER. I HAVE BEEN TOLD SEVERAL TIME BY THE MECHANIC AT CHEVY THAT THE IDLER PULLEY IS CONSTANTLY A PROBLEM. *TR

PURCHASED USED 38K MILES PROBLEMS STARTED STRAIGHT AWAY REARDOOR LOCKS QUIT, CHILD SAFETY LOCK ROD FELL OFF BROKEN CLIP, WOULD FIND PLASTIC TRIM ON GROUND NEXT TO CAR,SEAT TRIM BROKEN FELL OFF, WHEN IT RAINS OR SNOWS 4 WHEEL UNIT FAIL TO ENGAGE AND DISENGAGE CORRECTLY ENGINE LIGHT COMES ON AND GOES OUT ALOT ALTERNATOR IS LOUD WATER PUMP WENT OUT ,REAR CHEVY EMBLEM POPPED OFF WE NOW HAVE 56K CAN'T IMAGINE WHAT'S NEXT. *TR

I BOUGHT A BRAND NEW 2006 CHEVY TRAILBLAZER IN JAN. 19, 2006. ON JAN. 20, 2009 THE 4-WHEEL DRIVE COMPONENT IN THE TRAILBLAZER QUIT WORKING. NOW I AM OVER THE 36,000 MILES - I HAVE APPROX. 44, 000 MILES ON THE TRAILBLAZER. THE 4 WHEEL-DRIVE WILL NOT WORK IN 4WD HI, 4WD LO OR AUTOMATIC 4WD. I LIVE IN NORTHWESTERN PA AND NEED 4WD, ESPECIALLY THE WINTER OF 2009. THERE HAVE BEEN NUMEROUS OCCASIONS THAT I HAVE SLID ON THE ROAD NARROWLY MISSING AN ACCIDENT DUE TO NOT HAVING 4 WHEEL DRIVE. I CALLED SEVERAL DEALERS AND ASKED IF THEY HAD PROBLEMS BUT WAS TOLD ONE OF TWO ANSWERS: 1. THAT'S WHAT HAPPENS WHEN YOU BUY A 4 WHEEL DRIVE VEHICLE OR 2. THERE'S NOTHING WE CAN DO ABOUT IT. I HAVE NEVER HEARD OF THIS PROBLEM WITH ANY OTHER MODEL ON SUCH LOW MILEAGE! *TR
