2005 Chevrolet Trailblazer

I AM EXPERIENCING THE SAME LIGHT DIMMING/VOLTAGE DROP ISSUE ON MY '05 CHEVROLET TRAILBLAZER THAT I SAW REPORTED BY MANY OTHERS ON THE WWW. VEHICLE HAS BEEN IN TO DEALER TWICE FOR THIS ISSUE, I AM TOLD THAT LIGHTS DIMMING DURING QUICK DECELERATION WAS NORMAL, AND CAUSED BY AIR PUMP. WHILE GM MAY CONSIDER THIS NORMAL, I OBJECTED TO THAT CHARACTERIZATION AS ITWAS NOT ACCEPTABLE TO HAVE HEADLIGHTS AND ENTIRE ELECTRICAL SYSTEM DIMMING RANDOMLY WHILE DRIVING, ESPECIALLY AT NIGHT. THIS PRESENTS A LEGITIMATE SAFETY ISSUE. HOW CAN WE FORCE GM TO ADDRESS THIS ISSUE? *AK

MY HEADLIGHTS DIM WHILE DRIVING ,FIRST NOTICED WHILE DRIVING ABOUT 25 MI. FROM HOME AND THEY WOULD GO DIM AND THE GAGE WOULD DROPBELOW 14 AND THEN THEY WOULD BRIGHTEN UP AND THE GAGE WENT ABOVE 14, HAS DONE THIS ON SEVERAL OCCASIONS DEALER TOOK IT HOME OVER NIGHT TO SEE WHAT WAS GOING ON AND OF COURSE IT DIDN'T DO IT , HE SHOWED ME A PRINT OUT THAT SAID NOT TO REPLACE THE ALTERNATOR THAT THERE WAS NO PROBLEM WITH IT, IT CONTINUES TO DO THIS AND IT SEEMS TO ME THAT THERE IS A PROBLEM BUT UNTIL THEY SEE IT I'M JUST STUCK WITH IT , ANY SUGGESTIONS!. *AK

WHILE DRIVING AT NIGHT (MORE NOTICEABLE), THE HEAD LIGHTS APPEAR TO DIM THEN BRIGHTEN (FLASHING THE VEHICLE AHEAD). WHILE THIS IS OCCURING, THE BATTERY GAUGE BOUNCE DRASTICALLY FROM MIN TO MAX THEN BACK TO THE MIDDLE. THIS HAS BEEN OCCURING SINCE THE DAY I BOUGHT THIS VEHICLE JUNE 05. ALSO WHILE THIS OCCURS, THE VEHICLE TENDS TO LOSE RPM POWER SO AS YOU ARE DRIVING THERE IS A "JERK" IN THE FORWARD MOTION. *JB

WHEN I START UP MY TRAILBLAZER AND DRIVE OFF THE HEADLIGHTS AND DASH LIGHTS FLASH AND FLICKER. I HAVE TAKEN TO THE DEALERSHIP TWICE FOR REPAIRS AND THEY FIND NOTHING WRONG, AND GAVE ME A BULLETIN FROM GM THAT STATED THIS IS A NORMAL OPERATING CHARACTERISTIC DUE TO A SECONDARY AIR PUMP DIAGNOSTIC ROUTINE, AND THAT THERE IS NOTHING TO FIX. I THINK THIS IS WRONG. THE LIGHTS FLASH SO MUCH PEOPLE THINK I AM FLASHING MY LIGHTS AT THEM. IF I SIT AND IDLE FOR 30 SECONDS OR SO, SOMETIMES THAT HELPS, SOMETIMES IT DOESN'T (THIS WAS GM'S "FIX"). IF IT'S COLD I HAVE TO IDLE IT FOR SEVERAL MINUTES, AND EVEN THEN IT DOESN'T ALWAYS STOP IT. I HAVE HAD TO PULL OFF TO THE SIDE OF THE HIGHWAY, STOP MY ENGINE, START IT AGAIN, WAIT SEVERAL MINUTES, THEN MERGE BACK INTO TRAFFIC AND JUST PRAY THE LIGHTS DIDN'T START FLICKERING AGAIN. THIS SHOULD BE MADE A RECALL AND THEY SHOULD BE FORCED TO FIX THIS. I HAVE CONTACTED THEM REPEATEDLY AND GOT NOWHERE WITH THEM. *JB

MY WIFE DRIVES A 2005 CHEVROLET TRAIL BLAZER. ONE DAY ABOUT 1-2 MONTHS AGO SHE WAS COMING HOME FROM WORK, ABOUT 20 MILES, AND THE HEADLIGHTS AND INSTRUMENT LIGHTS STARTED FLASHING ON AND OFF. THIS HAPPENED ALL THE WAY HOME. I TOOK IT TO SMITH CHEVROLET IN LAURENS, S.C. (29360) TO HAVE IT REPAIRED. I WAS TOLD THERE WAS NO FIX AND CHEVROLET WAS AWARE OF THE PROBLEM AND THAT THIS WAS ALSO A PROBLEM ON THE ENVOY. I WAS TOLD IT WAS BECAUSE OF THE DRAIN ON THE ELECTRICAL SYSTEM WHEN A NUMBER OF COMPONENTS WERE DRAWING CURRENT AND THE SMOG SYSTEM OR PUMP CAME ON. I WAS GIVEN A FLYER THAT STATED WHAT COULD CAUSE THE PROBLEM OF WHICH NONE COULD I ATTRIBUTE TO MY WIFE'S DRIVING STYLE. I HAVE BEEN CONTACTED BY A PERSON SAYING HIS NAME IS JEREMY AT 866-790-5700 EXT. 22087. JEREMY OFFERED TO GIVE US A 12 MONTH 12,000 OR 18,000 MILE EXTENDED WARRANTY FROM THE DATE OF SERVICE AT SMITH'S. THE CAR HAS ABOUT 29,000 MILES ON IT SO THE WARRANTY WOULD BE FOR ABOUT 5,000 MILES. I DO NOT WANT AN EXTENDED WARRANTY. I WANT THE CAR FIXED, REPLACED OR REFUND. THIS IS A VERY DANGEROUS SITUATION FOR MY WIFE. SHE IS OUT AT NIGHT WITH OUR 9 YEAR OLD SON AND SHE DOES NOT FEEL SAFE. I DON'T KNOW DATE EXACTLY. IT IS ESTIMATED. THIS HAS HAPPENED A SECOND TIME BUT NOT TAKEN IN YET. *JB

2005 CHEVROLET TRAILBLAZER'S HEADLIGHTS FLICKERED ON AND OFF. **CC SOMETIMES THE FLICKERING LAST FOR A FEW SECONDS OTHER TIMES IT HAS LASTED UP TO 10 MIN. THE DEALER WAS ABLE TO DUPLICATE THE PROBLEM BUT STATED THERE WAS A TSB FROM CHEVROLET WHICH STATED THE FLICKERING WAS NORMAL. THEREFORE THERE WERE NO REPAIRS ATTEMPTED. THE BRAKES PULSATED DUE TO RUST ON THE ROTORS. *NM

PURCHASED 2005 CHEVROLET TRAILBLAZER LS OCT.28 06. SINCE THEN, TO DATE, VEH. HAS BEEN IN SHOP (DEALERSHIP 4X). 1. BRAKE REPAIR. ALL 4 CALIPERS WERE REPLACED. THIS VEHICLE HAD ONLY 22,000. MILES. IN SHOP VERY 1ST WEEK OF PURCHASE. 2. BEEN COMPLAINING OF FLICKERING LIGHTS. WAS HANDED A GMC PRINTOUT STATING THEY DID NOT KNOW CAUSE. SO THEREFORE THE DEALERSHIP, HOOD CHEVROLET, COVINGTON LA. COULD NOT DO ANYTHING ABOUT IT. 3. COMPLAINED OF ENGINE ACCELERATION WHILE APPLYING BRAKE, COMING TO A STOP OR A SLOW SPEED IN A PARKING LOT. FEAR THAT I MAY CRASH INTO SOMEONE. RECEIVED PRINTOUT FROM GM STATING THIS WAS NORMAL. BUT I SEE THIS IS A HAZARD. 4. COMPLAINED OF SEAT BELT "RIDING" ON THE NECKLINE, RESTRICTING BLOOD FLOW IN LEFT ARTERY ON NECK. I SEE THIS A MAJOR PROBLEM. I COMMUTE 26 MILES ONE WAY TO WORK AT A HOSPITAL. I THOUGHT I WOULD BE SAFER DRIVING MY TRAILBLAZER, NOW I FEAR FOR MY LIFE. 5. COMPLAINED OF POPPING ON FRONT END. SERVICE HAD TO ORDER SWAY LINKS AND REPLACE. DID NOT SOLVE PROBLEM, STILL HAVE FRONTAL POPPING WHILE TURNING LEFT OR RIGHT, REVERSE AND FORWARD. IT IS PROGRESSIVELY GETTING WORSE. FOUND OUT GM CERTIFIED TECH. DID NOT PROPERLY ALIGN CALIBERS WHEN INSTALLED. I HAVE PAID TO MUCH FOR THIS $23,000. LEMON. ACTION SHOULD BE TAKEN. SARAH DYKES, BOGALUSA LOUISIANA. *NM

ON 2 DIFFERENT TIMES I HAVE TAKEN MY 05 TRAILBLAZER TO THE DEALER FOR WORK TO DONE ON WHAT WE THOUGHT WAS THE ALTERNATOR. THE HEADLAMPS AND INSIDE LAMPS WILL DIM AND THE BATTERY CHARGE GAUGE WILL DROP BELOW THE 14 AMPS GM CALL NORMAL. I HAVE BEEN TOLD THAT THIS IS A NORMAL CONDITION. I FEEL IT IS ANYTHING BUT NORMAL AND IT IS A SAFETY ISSUE. PEOPLE THINK YOU ARE BRIGHT LIGHTING THEM AND IT IS JUST PLAIN HARD TO SEE AT TIMES. IT SEEM TO HAPPEN MORE WHEN IT IS COLD AND DAMP. THIS IS NOT NORMAL, AND UNLESS GM DECIDES TO FIX THIS PROBLEM WE WILL NOT BUY ANOTHER GM PRODUCT! *JB
