2005 Chevrolet Trailblazer electrical system problems

“FOR SEVERAL YEARS THE LOW BEAM HEADLIGHTS WOULD GO OFF AND ON INTERMITTENTLY. NOW, THEY ARE MOSTLY OFF WHICH MEANS I CANNOT DRIVE MY VEHICLE AT NIGHT ANYMORE UNLESS I WANT TO BLIND PEOPLE OR GET STOPPED. I HAVE CHANGED HEADLAMPS, RELAYS AND FUSES TO NO AVAIL. NOW, I SEE THAT MANY OTHERS WITH THE SAME MAKE AND MODEL SUV HAVE BEEN HAVING THE SAME ISSUE BUT NO RECALLS HAVE BEEN ISSUED FOR THIS YEAR MODEL. THIS IS A MAJOR SAFETY ISSUE WHEN WE HAVE TO DRIVE WITH THE HIGH BEAMS ON AND WHEN THE LIGHTS GO OFF UNEXPECTEDLY. IF YOU WILL ISSUE A RECALL FOR ONE YEAR MODEL HAVING A PARTICULAR ISSUE, WHY WOULD YOU NOT DO THE SAME WITH ALL YEAR MODELS HAVING THE SAME ISSUE? COME ON CHEVROLET AND NHTSA, LET'S GET THIS PROBLEM SOLVED TO SAVE SOME LIVES. IT IS VERY SCARY TO BE DRIVING AND HAVE YOUR HEADLIGHTS GO OUT AND A MAJOR PAIN TO HAVE TO BE SURE YOU ARE HOME BY DARK OR NOT BE ABLE TO GO OUT AFTER DARK BECAUSE YOUR HEADLAMPS ARE OR MAY STOP WORKING.”

“I OWN A 2005 CHEVROLET TRAILBLAZER (BOUGHT NEW) WITH APPROXIMATELY 79,000 MILES. THE FUEL GAUGE LIGHT IS ILLUMINATED INDICATING I AM LOW ON FUEL HOWEVER MY GAS TANK IS FULL. I NOTICED THE PROBLEM AFTER FILLING MY TANK (NO LIGHT ON AT THE TIME). AFTER FILLING THE TANK, THE FUEL LIGHT CAME ON AND THE GAS GAUGE BOUNCED BACK AND FORTH FROM QUARTER TANK TO HALF TANK AND NOW THE LIGHT STAYS ON WITH GAUGE SHOWING EMPTY. I WOULD APPRECIATE ANY HELP YOU CAN GIVE OR RECOMMEND ANY POSSIBLE ACTION TO TAKE.”

“MOST RECENT, I AM DRIVING DOWN THE ROAD MY HEAD LIGHTS GO OUT. NOTHING ELSE, JUST THE MAIN HEAD LIGHTS. ALL.OTJER LIGHTS STAY ON. HIGH BEAMS WORK, PARKING LIGHTS STAY ON. THIS IS NOT SAFE!!!”

“THE SPEEDOMETER ISN'T WORKING. I'VE BEEN HEARING HOW COMMON THIS ISSUE IS. EVERY NOW AND THEN IT WILL JUMP TO A RANDOM SPOT WHEN I START THE VEHICLE AND STAY THERE. BUT IT NEVER MOVES WHILE DRIVING”

“IN MOTION OR PARKED MY SPEED AND MY TAC JUST STOP AT RANDOM NUMBERS. I HAVE TO SHUT MY CAR OFF IF MY SPEED IS STUCK. EVERYTIME I DO THIS MY SPEED DROPS 5 MPH SO IF I'M STUCK AT 20 I HAVE TO DO THIS 4 TIMES JUST TO GET BACK TO 0 MPH I HAVE CALLED CHEVY . THEY TOLD ME IT WILL COST ME OVER $800 TO FIX THIS. KINDA STRANGE THE RECALL DOAENT EFFECT ONLY THE TRAILBLAZERS DON'T YOU THINK. I HAVE BEEN IN THE AUTOMOTIVE FEIOD FOR OVER 10 YEARS NOW AND I KNOW ALOT OF CHEVY HAVE HAD THIS RECALL SO IT'S TIME FOR YOU GUYS ACT.”

“VEHICLE PURCHASED 2008. IT HAD 35,412 MI. IN 2011 THE VEHICLE WOULD HAVE A ROUGH IDLE AND STALL IN TRAFFIC. SOMETIMES AS MANY AS 3 TIMES ON A SIX MILE ROUND TRIP. ALWAYS WOULD STALL DRIVING AROUND TOWN. I HAD REPLACED CAM VRR TEMP SENSOR FUEL THROTTLE. ALL COILS PLUGS WATER PUMP BATTERY MOTOR SUPPORTS BELT WINDSHIELD WASHER BOTTLE AND MOTORS FLUSH FUEL LINES. WHEEL HUBS AND BEARING ROUNDS CRANKSHAFT AND POWER STEERING PULLEY POWER STEERING PUMP OIL CHANGES 2500 TO 3000 MILES SYNTHETIC OIL. ALL FLUIDS CHANGED AND FLUSH REAR DIFFERENTIAL TRANSMISSION SHIFTER CABLE. SEVERAL DIAGNOSTICS AT CHEVROLET. LEFT THERE THEY DROVE IT CUT OFF ONCE. FINALLY, I KEPT WATCHING GAUGES OIL PRESSURE DROPPED 44 TO ZERO. CAR CUT OFF RECTANGLES IT PULLED OVER WAIT 30 MINS. NO OIL ON DIP STICK. CALLED FIRESTONE TOOK IT THERE. OIL SENDING UNIT DEFECTIVE.
