2005 CHEVROLET TRAILBLAZER Engine Problems

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that after his wife had parked the vehicle at a high school parking lot, a passerby heard a clicking noise and saw smoke coming from the vehicle before the vehicle caught-on fire. The fire started in the engine compartment. The fire department was contacted and arrived and extinguished the fire. The contact was unaware if a fire report was filed. The vehicle was towed from the scene to a holding lot. The vehicle was not repaired. The manufacturer was not contacted or notified of the failure. The approximate failure mileage 63,000.

TL* THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. WHILE DRIVING APPROXIMATELY 60 MPH, THE VEHICLE DECELERATED TO 30 MPH AND SHUT DOWN AT A SLIGHT ELEVATION. IN ADDITION, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE FAILURE OCCURRED TWO DAYS AFTER THE VEHICLE WAS PURCHASED FROM AN INDEPENDENT MECHANIC. THE CONTACT CALLED THE MECHANIC AND WAS INFORMED THAT THE VEHICLE WOULD BE PICKED UP FOR DIAGNOSTIC TESTING. THE VEHICLE WAS NOT REPAIRED. THE DEALER WAS NOT CALLED AND THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 173,000.

VEHICLE ENGINE STALLS WHILE DRIVING. THE CAR SHUTS OFF WITHOUT WARNING. THIS IS DANGEROUS AND NOT SAFE! I SHUT OFF WHILE DRIVING ON THE HIGHWAY AND WHEN I WAS ABLE TO GET IT OFF THE HIGHWAY, IT STOPPED IN THE CITY. REPLACED THE ELECTRICAL BODY PER THE DIAGNOSIS AND STILL EXPERIENCING THIS ISSUE

SINCE THE PURCHASE MY TB ENGINE WILL STOP WHEN AC AND HEATER IS ON ON STOP LIGHT, THAT IT WAS DELAYING WHILE DRIVING. IT GOT WORSE AFTER "WARRANTY WAS OUT, I BELIEVE IN JULY 2007.NO ONE CAN FIND THE CAUSE, BUT THINKING ITS ALL SYSTEM FAULTY., ENGINE, ELECTRONICS, FANS. COULD I AFFORD A NEW CAR, I WOULD NOT KEEP THIS CAR, AS NOW I KNOW IT WAS THE WORSE YEAR MAKING OF ALL. NOW I ONLY PRAY TO STAY ALIVE WHILE DRIVING AND NOT GET INTO SOME BEYOND MY CONTROL BUT FAULTY GM MODEL MAKERS

TL* THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. WHILE DRIVING AT 50 MPH, THE VEHICLE SUDDENLY REDUCED SPEED TO 20 MPH AND JERKED ABRUPTLY.

THE MANUFACTURER WAS CONTACTED AND DID NOT ASSIST. THE APPROXIMATE FAILURE MILEAGE WAS 115,000.

VEHICLE SHUTS OFF WHEN SITTING IDLE OR WHEN CHANGING BETWEEN THE GAS AND BRAKES. I WAS HIT IN THE REAR THIS MORNING WHILE SITTING IN TRAFFIC. THANKFULLY NEITHER VEHICLE WAS DAMAGED. I GOOGLED THIS ISSUE A D THERE ARE THOUSANDS OF ISSUES.

TL* THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. WHILE OPERATING THE VEHICLE, SMOKE EMITTED FROM THE HOOD. THE CONTACT PULLED OVER AND DISCOVERED FLAMES UNDER THE HOOD. THE FIRE DEPARTMENT EXTINGUISHED THE FIRE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE FAILURE WAS DUE TO A FAILED GM/AC DELCO TRANSMISSION COOLANT LINE FITTING, WHICH CAUSED TRANSMISSION COOLANT TO LEAK OUT ONTO THE CATALYTIC CONVERTER AND EXHAUST SYSTEM. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 120,000.

CAR WILL NOT ACCELERATE. REVS UP REALLY HIGH WITHOUT ACCELERATION.

TL* THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE STEERING WHEEL BECAME DIFFICULT TO TURN AND THE SPEEDOMETER FAILED. IN ADDITION, THE REAR HATCH LOCK FAILED CAUSING THE CONTACT TO BE UNABLE TO UNLOCK THE REAR HATCH AND THE FRONT ROTORS FAILED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO REPLACED THE POWER STEERING PUMP AND THE FRONT ROTORS. THE SPEEDOMETER AND REAR HATCH WERE NOT REPAIRED. THE CONTACT ALSO STATED THAT THERE WAS A STRONG ABNORMAL ODOR PRESENT INSIDE THE VEHICLE AND THE ENGINE WARNING LIGHT ILLUMINATED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 58,584.

THE HEADLIGHTS WORK THEN SHUT OFF. (ON THE WAY TO WORK IN A DOWNPOUR, NO LESS) DASHBOARD LIGHTS PARTIALLY WORKING. (IF I GO OVER 40 MPG CAN'T TELL WHAT MY SPEED IS) WAS WORKING CORRECTLY FOR A COUPLE OF DAYS NOW NOTHING. I CHECKED FOR RECALLS AND THERE ARE RECALLS FOR 2006-20XX (NHTSA 14V755000 ) JUST WONDERING, AFTER FINDING ON THE INTERNET, NUMEROUS 2005 OWNERS WITH SAME PROBLEM, WHY THIS MODEL WASN'T INCLUDED IN THE RECALLS? I WOULD LIKE TO FILE A COMPLAINT ON THE POTENTIALLY DEADLY PROBLEM OF THE 2005 CHEVY TRAILBLAZER THAT SHOULD BE CORRECTED AND INCLUDED IN THIS RECALL. THANK YOU *TR

THE ENGINE LIGHT CONSTANTLY COMES ON EVEN AFTER I HAD A TUNE UP. I HAD DIAGNOSTICS DONE AND THERE IS SOME TYPE OF FUEL MISFIRE. TWO WINTERS STRAIGHT I HAVE HAD ISSUES WITH THE POWER STEERING LINES BURSTING AND REPLACED 3 TIMES. THE SPEEDOMETER MALFUNCTIONS, MOST OF THE TIME IT JUST STAYS AT ZERO. IF GM USES A LOT OF THE SAME PARTS TO MAKE MULTIPLE MODELS WHY HAS THE 2005 TRAILBLAZER NOT BEEN RECALLED? I WAS TOLD THE GM ENVOY HAS THE SAME ENGINE AND OTHER INNER WORKINGS AS MY TRAILBLAZER SO WHY WOULDN'T THEIR RECALLS APPLY TO MY VEHICLE ESPECIALLY IF I MAY BE HAVING THE SAME ISSUES. *TR

MULTIPLE TIMES WHILE DRIVING THE HEADLIGHTS WILL MALFUNCTION AND TURN ON AND OFF, AT RANDOM DRIVING SPEEDS UNDER MANY DIFFERENT CONDITIONS. I CONTINUED TO DRIVE THE TRAILBLAZER EVEN AFTER THIS OCCURRED. JUST NOT AS OFTEN. IF THE HEATER WAS ON WHILE DRIVING AND THE HEADLIGHTS WOULD SHORT THE HEATER WOULD STOP AND THEN TURN BACK ON. THE FAN TURNS ON AT RANDOM, FIRST IT TURNS ON WHEN DRIVING AT RANDOM TIMES. THE FAN WILL TURN ON AT RANDOM TIMES WITH A HIGHER SPEED AND SOUND. I HAVE HAD THE INSPECTION COMPLETED MULTIPLE TIMES WITH A MECHANIC RE-ASSURING THE ISSUE ALTHOUGH IT HAS BEEN HAPPENING FREQUENTLY. THE CHECK ENGINE LIGHT IS ON ALL THE TIME DUE TO COMPUTER ERROR AND IS A $500.00 FIX. THIS HAS ALL HAPPENED AND BEEN REPORTED WITHIN THE FIRST YEAR I BOUGHT THE VEHICLE FROM KENDAL MOTORS IN LEWISTON IDAHO. I FIND THAT THE AMOUNT OF...

PULLED UP TO A RED LIGHT AND STOPPED. SHORTLY AFTER, COMING TO A COMPLETE STOP, THE ENGINE JUST SHUT DOWN. NO WARNING LIGHTS HAD COME ON PRIOR TO THE ENGINE SHUTTING DOWN. JUST LOST ALL POWER INSTANTLY. I TURNED THE KEY, AS YOU WOULD TO START THE VEHICLE, AND IT STARTED RIGHT UP. VERY GLAD IT DID NOT HAPPEN WHILE I WAS ON THE EXPRESSWAY OR WHILE MOVING. I CAN'T HELP BUT WONDER IF IT IS AN IGNITION PROBLEM, AS THAT WHICH PLAGUES OTHER GM PRODUCTS. ALSO, I HAVE THE RADIO ON WHILE DRIVING AND ON MULTIPLE OCCASIONS, AFTER TURNING OFF THE CAR AND OPENING THE DOOR TO GET OUT, THE RADIO REFUSES TO STOP PLAYING (IT IS SUPPOSED TO, AND IT USED TO, CEASE OPERATING WHEN YOU OPEN THE DRIVER'S DOOR). I AM FORCED TO OPEN THE BACK VEHICLE DOOR TO GET IT TO STOP. I WONDER IF THIS...

TL* THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. WHILE DRIVING 55 MPH, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED AND THE VEHICLE STALLED. WITHIN FIVE MINUTES, THE VEHICLE RESTARTED BUT THE CHECK ENGINE INDICATOR REMAINED ILLUMINATED. THE FAILURE OCCURRED FOUR TIMES. THE VEHICLE WAS TAKEN TO A DEALER WHO CONFIRMED THAT THE THROTTLE BODY NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 150,000.

THE CHECK ENGINE LIGHT COMES ON&OFF A LOT RIGHT AFTER FUELING, I TOOK IT TO THE GMC DEALERSHIP&HAD THE CAMSHAFT REPLACED BECAUSE IT KEPT CUTTING OFF EVERY TIME I TURNED A CURVE.I TRIED TO SHOW OR TELL THEM ABOUT THIS GMC RECALL LETTER I GOT ON MY 2005 CHEVROLET TRAILBLAZER, BUT THEY SAID THAT IT DIDN'T APPLY BECAUSE OF THE MILEAGE&I TOLD THEM THE CAR IS NOT 10YRS OLD& THE PAPER IS SAYING 10YRS/120,00 MILES& FOR ME TO TAKE IT TO THE DEALERSHIP SO THAT THE MANGER CAN SEND MY BILL & RECEIPT IN FOR REIMBURSEMENT THEY WOULDN'T DO IT.I GUESS BECAUSE I'M A WOMAN.DRIVING TO WORK ON THE INTERSTATE THE CAR SHUT COMPLETELY OFF. THE CAR WAS STILL MOVING WHEN ALL OF A SUDDEN ALL THE LIGHTS AND GAUGE'S LIT UP AND THE CAR CUT OFF. IT DID NOT LOCK UP SO I WAS ABLE TO STEER IT FROM...

I AM THE OWNER OF A 2005 CHEVROLET TRAILBLAZER WITH 32,000 MILES. I PURCHASED THE TRUCK NEW FROM THE DEALER. OVER THE FEW YEARS THAT I HAVE OWNED THE VEHICLE, I HAVE BEEN FACED WITH A MULTITUDE OF ISSUES. MY FIRST PROBLEM BECAME THE AC LINES. THEY BEGAN TO LEAK DUE TO RUST, WHICH WAS NOT COVERED UNDER THE 7 YEAR, 70,000 MILE WARRANTY. NEXT THE EXHAUST MANIFOLD BEGAN TO LEAK. THE COST WAS COVERED UNDER THE WARRANTY; HOWEVER, THE DEALER MANAGED TO BREAK THE BOLTS THAT HOLD THE MANIFOLD TO THE ENGINE. THE BREAKAGE WAS NOT COVERED, AND THEREFORE, I HAD TO PAY. FOLLOWING THESE TWO ISSUES, I NOTICED RUST ALL OVER THE UNDERCARRIAGE. IN THE PAST THREE YEARS, AFTER MY WARRANTY EXPIRED, I HAD TO FIX THE FOLLOWING ITEMS DUE TO THE RUST: THE POWER STEERING COIL, REAR END, TRANSMISSION, FUEL PUMP, POWER STEERING LINES, POWER STEERING PUMP,...

MY CAR HAS SHUT DOWN WHILE IDLING AT A STOP SIGN OR RED LIGHT. THE FIRST TIME WAS IN 2006, BUT HAS HAPPENED SEVERAL TIMES SINCE THEN. I'VE TAKEN IT TO THE DEALERSHIP, BUT THEY SAID THAT THEY COULDN'T SEE ANYTHING WRONG WITH MY VEHICLE. I BELIEVE THAT MY FUEL GAUGE IS INACCURATE. IT SHOWED EMPTY, AND, THEN 1/4 TANK. THE REAR WIPER SWEEPS WITHOUT BEING TURNED ON. *TR

SIR/ MA'AM, I NOTICED RECENTLY IN THE NEWS THAT SEVERAL GM PRODUCT LINES HAVE BEEN PLAGUED BY FAULTY IGNITION SWITCHES CAUSING THE VEHICLE TO LOSE POWER AND/OR CUT OUT. I IMPLORE YOU TO LOOK INTO THE TRAILBLAZERS. I EMAILED GM WHILE I WAS DEPLOYED (2012) AND THEY GAVE ME THE RUNAROUND SAYING THAT IT IS NOT A DOCUMENTED PROBLEM, AS EXPECTED. A SIMPLE INTERNET SEARCH WOULD SHOW THAT A LOT OF OTHER TRAILBLAZER OWNERS HAVE BAD IGNITION SWITCHES/ ELECTRICAL ISSUES THAT CAUSE THE VEHICLE TO LOSE POWER AT ALL SPEEDS. MY WIFE LOST POWER GOING ABOUT 35 MPH AND I HAD MY TWO CHILDREN ALONG WITH HER. THIS IS JUST ONE EXAMPLE, ON ONE OCCASION. GRANTED, I DO ACKNOWLEDGE THIS PROBLEM IS INTERMITTENT, IT STILL OCCURS AT RANDOM AND AT ALL SPEEDS. GM TELLS ME TO GO TO A DEALER AND HAVE THEM LOOK AT IT. I REFUSE TO PAY...

SPEEDOMETER RANDOMLY PARKS ON 0 MPH NO MATTER WHAT THE SPEED IS. THE FUEL GAUGE RANDOMLY INDICATES "E" OR OTHER INACCURATE FUEL READINGS REGARDLESS OF HOW MUCH FUEL IS IN THE TANK. THE CAR RANDOMLY STALLS WHEN STOPPED AT TRAFFIC LIGHTS. *TR

WE WERE DRIVING AT ABOUT 55 (WE DON'T KNOW EXACT SPEED AS OUR CONTROL PANEL IS NOT WORKING) AND THE STEERING WENT OUT. IT WAS HARD PULLING TO THE RIGHT AND A FEW TIMES WE COULD NOT CONTROL IT AND WENT OFF THE ROAD. WE HAD ANOTHER INCIDENT LIKE THAT WHEN WE WERE DRIVING IN THE SNOW. WHEN WE PURCHASED THE CAR WE HAD A FUEL ISSUE THAT COVERED UNDER A RECALL.... NOW OUR WHOLE PANEL IS OUT. WE DON'T KNOW THE SPEED WE ARE GOING, THE OIL LIGHT AND ENGINE LIGHT ARE ALWAYS ON. WE TAKE CARE OF OUR CAR SO WE KNOW ITS NOT LOW ON ANYTHING. *TR

PROBLEMS WITH MY 2005 CHEVY TRAILBLAZER STARTED WITH A SERIES OF ENGINE LIGHTS, MISFIRING AND STALLING AT LOW SPEEDS AND UPON ACCELERATION. MY THERMOSTAT HAS BEEN REPLACED NUMEROUS AMOUNT OF TIMES . I DO PREVENTATIVE MAINTENANCE TO KEEP MY CAR IN GOOD WORKING CONDITION. I'M A SINGLE PARENT I NEED MY CAR. MY ENTIRE DASHBOARD STOPPED WORKING AFTER GETTING STUCK ON AND OFF. THE FUEL GAUGE WAS LAST TO GO 3 DAYS AGO. I FILL UP MY TANK IT STILL READS EMPTY WITH THE LIGHT. MY TAILGATE DOOR THE LATCH LOCKS UP. I MANUALLY HAVE TO MOVE TO LATCH SO IT CLOSES. MY DOORS STICKING WHEN THE CAR IS UNLOCKED AND IT HARD TO GET OUT THE LOCKS DON'T UNLATCH THE FIRST TIME. MY CAR IS VERY NICE UNTIL U GET IN IT TO SEE EVERYTHING IS MALFUNCTIONING. I GUESS MY SPEED, GAS LEVEL AND THAT'S NOT COOL. I BEEN...

TL* THE CONTACT OWNS A 2005 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT WHILE TRAVELING APPROXIMATELY 40 MPH, THE VEHICLE SUDDENLY STALLED AND VEERED INTO ONCOMING TRAFFIC. THE DRIVER CRASHED INTO ANOTHER VEHICLE AND THE AIR BAGS FAILED TO DEPLOY UPON IMPACT. THE DRIVER SUSTAINED FACE, BACK, AND NECK INJURIES. THE DRIVER OF THE SECOND VEHICLE WAS NOT INJURED. THE VEHICLE WAS DESTROYED. THE MANUFACTURER WAS NOT CONTACTED ABOUT THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED. THE FAILURE MILEAGE AND VIN WAS NOT AVAILABLE.

MY TRAILBLAZER 2005 WOULD BE DRIVING DOWN THE STREET AT ABOUT 25 TO 30 MILES, THEN MY ENGINE WOULD JUST TURN OFF WITH OUT ANY WARNING, AM AFRAID IT WILL HAPPEN AGAIN BUT THIS TIME WHEN AM IN THE HIGHWAYS GOING 60 MILES ON THE HIGHWAY I SEEN THAT IS NOT JUST MY VEHICLE THAT HAS HAPPENED TO AND EVEN THE FUEL PUMP HAS GAVE UP WITH OUT NO ANSWER, THE GM OR CHEVROLET DEALERSHIP DON'T HAVE A CLUE WHY THIS IS HAPPENING. IT WILL BE REALLY HELPFUL IF YOU GUYS LOOK INTO THIS BEFORE SOMEONE GETS HURT ON THIS MALFUNCTION. I REALLY APPRECIATE FOR TAKING YOUR TIME. SINCERELY, CHEVROLET TRAILBLAZER DRIVER *TR

DRIVING AT A LOW SPEED THROUGH A RESIDENTIAL AREA THE ENGINE WOULD SERGE BETWEEN 2K RPM AND 4K RPM. IF SURGING IS ALLOWED TO PERSIST THEN IT IS FOLLOWED BY THE VEHICLE'S POWER STEERING SHUT OFF ULTIMATELY ENDING IN THE ENGINE SHUTTING OFF. AFTER VEHICLE IS RESTARTED THE CYCLE STARTS AGAIN AFTER A SHORT PERIOD OF DRIVING. *TR

EVEN IF THIS CAR IS WELL MAINTAINED IT SADLY AS SERIOUS ELECTRICAL ISSUES THAT CHEVY DOES NOT WANT TO COME TO TERMS WITH. THE SPEEDOMETER GOES OUT AND IN AND READS INCORRECTLY AS WELL AS THE REST OF THE GAUGES AT RANDOM POINTS IN TIME. THE HEATING SYSTEM NEEDS REPLACES AND THE ALTERNATOR CONSISTENTLY NEEDS TO BE REPLACED EVEN WHEN THE MAINTENANCE OF THE CAR IS MAINTAINED. IT IS A CONSISTENT STRUGGLE TO KEEP THE CAR RUNNING EVEN IF IT IS NOT ON HIGH MILES AND IT IS A SAD PRODUCT FOR CHEVY. *TR

2005 CHEVROLET TRAILBLAZER. CONSUMER WRITES IN REGARDS TO VEHICLE FUEL GAUGE SENSOR ISSUES. *SMD THE CONSUMER STATE THE FIRST TIME THE FUEL GAUGE STARTING ACTING ERRATIC WAS IN 2007. THE DEALER INFORMED HIS WIFE, THE VEHICLE HAD RAN OUT OF GAS, EVEN THOUGH THE GAUGE INDICATED THERE WAS 1/2 TANK OF GAS. THE CONSUMER STATED HE CONTINUES TO EXPERIENCE AN ERRATIC BEHAVIOR OF THE FUEL PUMP AND THE LOW FUEL INDICATOR LIGHT ILLUMINATED. THE LATEST PRELIMINARY DIAGNOSIS WAS THE VEHICLE WAS UNABLE TO SUSTAIN AN IDLE, BECAUSE OF THE ERRATIC FUEL PRESSURE (FUEL PUMP). THE CONSUMER ALSO STATED THE VEHICLE HAS ELECTRICAL PROBLEMS AND THE OIL PRESSURE GAUGE WAS INOPERATIVE.

PURCHASED 11/24/2008 ~20K MILES. WITHIN 5MONTHS A WHOLE HOST OF ISSUES STARTED, THE 1ST BEING THE FUEL GAUGE NOT WORKING BY SHOWING FULL & ACTUALLY NOT (RAN OUT OF GAS TWICE) AND THEN SHOWING EMPTY AFTER FILLUP. 1WEEK LATER THE ENGINE LIGHT CAME ON & THE INSTRUMENT PANEL STOPPED WORKING. ~ ONE YEAR LATER, DEC 2009 THE SPEEDOMETER FLUCTUATED FROM WORKING PROPERLY TO ~50-55MPH BASE INSTEAD OF 0. AFTER A FEW DAYS, THE SPEEDOMETER DID ZERO-OUT BUT THEN DID NOT SHOW ANY SPEED BUT STAYED AT 0. ALONG WITH THE SPEEDOMETER ISSUE ARE THE HEADLIGHTS DIMMING SPORADICALLY. ALL OF THE ISSUES HAVE CONTINUED ON-OFF SINCE. MARCH 2012 THE WINDSHIELD RESERVOIR STARTED LEAKING/CRACKED. FEBRUARY 2013 HAD TUNEUP, BRAKES, AND THERMOSTAT REPLACED AND SINCE THEN ADD FRONT VENTS STOPPED WORKING PLUS SEVERE, SPORADIC, HIGH IDLE - DRIVING TO WORK (METROPOLITAN, DOWNTOWN, CAPITAL OF STATE-HIGH RUSH HOUR) THE HIGH REV STARTED AND ALL...

VEHICLE WOULD NOT START. HAD IT TOWED TO MECHANIC SHOP. BATTERY WAS COMPLETELY DEAD, THOUGH THE BATTERY WAS ONLY 1 YEAR OLD AND WAS A VERY EXPENSIVE AC DELCO 6 YR BATTERY. MECHANIC CHANGED THE ALTERNATOR AND THE BATTERY AND EVERYTHING TESTED THE SAME. PUT OLD BATTERY AND ALTERNATOR BACK IN, AS BATTERY HE CHARGED WAS HOLDING THE CHARGE OK. COULD NOT LOCATE SOURCE OF PROBLEM. THE NEXT DAY, THE DASH LIGHTS WERE NOT WORKING, NOR THE INTERIOR LIGHTS. AS I DROVE ALONG THE HIGHWAY, THE DASHLIGHTS BLINKED AND THEN STAYED ON. CEILING LIGHT WORKS INTERMITTENTLY. THE ALTERNATOR SHOWS THAT IT IS CHARGING VERY HARD. ACCORDING TO OTHER INCIDENTS REPORTED ON THE INTERNET, THERE IS AN ELECTRICAL PROBLEM IN THE 2005 TRAILBLAZER THAT MAY OR MAY NOT BE ASSOCIATED WITH THE PASSLOCK ANTI-THEFT SYSTEM, BUT IN ANY CASE, SHOWS SLOW LEAK OF ELECTRICAL CURRENT THAT SLOWLY DRAINS THE BATTERY 24/7,...

DUE TO A FAULTY GAS GAUGE THE CAR ENGINE STOPPED ON A HIGHWAY THREE MIILES AWAY FROM FUEL WITH CHILDREN IN THE VEHICLE. *TR
