2004 CHEVROLET TRAILBLAZER Complaints

MY SPEEDOMETER SOMETIMES READS ABOUT 20 MPH OFF THEN WON'T RESET WHEN I TURN THE VEHICLE OFF. IT JUST STAYS AT 20 MPH...THEN SOMETIMES IT DOES RESET AND WORKS FINE. I TOOK THE VEHICLE TO A CHEVY DEALERSHIP AND THEY SAID THAT SINCE THE PROBLEM WASN'T HAPPENING AT THE TIME I TOOK IT IN THEY COULDN'T DO ANYTHING EXCEPT RE-PROGRAM THE SPEEDO. THAT DIDN'T HELP, IT HAPPENED AGAIN AFTER THAT. *JB

2004 CHEVROLET TRAILBLAZER. IT SHOWED ZERO WHEN I AM GOING AT LEAST 40 MPH, THEN MOVES A LITTLE, AND NOW IS SHOWING LIKE 110 MPH WHEN I AM GOING AROUND 50 MPH. I HAVE NOTICED THAT THIS WAS A COMMON PROBLEM WITH MY VEHICLE. I HAVE AROUND 56,000 MILES ON IT. IS GM PLANNING ON A RECALL, THISWASA EXTREMELY DANGEROUS AND I SHOULD NOT HAVE TO BEAR THE COST OF REPAIRS. *AK

SPEEDOMETER DOES NOT WORK, SO I DO NOT KNOW HOW FAST I AM GOING. THE TEMPERATURE GAUGE SOMETIMES SAYS MY ENGINE IS TOO HOT WHEN IT IS NOT, SO NOW I AM NOT SURE ABOUT THE STATUS OF MY ENGINE'S COOLING SYSTEM. THIS IS AN ONGOING PROBLEM. I AM EXTREMELY CONCERNED AND DISCOVERED ON THE INTERNET THAT MANY PEOPLE ARE HAVING THIS PROBLEM.

THE SPEEDOMETER WENT TO 120 AND STAYED FOR A COUPLE OF DAYS AND THEN SLOWLY CAME BACK DOWN BUT WHEN TRAVELING 5 MPH IT WILL SAY 40 TO 90 DEPENDS HOW IT FEELS. GM WILL NOT BACK UP UNDER WARRANT. VEHICLE IS OUT OF WARRANTY BUT SEEMS TO BE A COMMON PROBLEM WITH CHEVROLET TRUCKS...VEHICLE IS A 2004 TRAILBLAZER ,WITH 40,000 MI.. *JB

INTERMITTENT HEADLIGHT AND VOLTAGE PROBLEMS, THE VEHICLE IS A 2004 TRAILBLAZER, THE PROBLEM BEGAN IN THE FALL OF 2004...HEADLIGHTS AND VOLTAGE GAUGE WOULD DIM AND DROP, WOULD CONTINUE TO DO THIS INTERMITTENTLY...DEALERSHIP REPLACED THE ALTERNATOR TWICE..ALSO THE DASH HAS BEEN REPLACED ONCE DUE TO THE VOLTAGE SPIKES CAUSED BY THIS...THE LAST TIME I TOOK IT IN THE SERVICE MANAGER TOLD ME THAT GM HAD ISSUED A BULLETIN ON THIS SAYING IT WAS " THE NATURE OF THE BEAST" THAT IT WAS CAUSED BY A SECONDARY SMOG PUMP THAT WAS SUPPOSED TO COME ON ONLY WHEN THE VEHICLE WAS 1ST STARTED...BUT COULD ALSO KEEP KICKING IN AND OUT CAUSING A SEVERE VOLTAGE DRAW...MY TRUCK NOW HAS 50,000 MILES ON IT, AM AFRAID THESE VOLTAGE SPIKES WILL TAKE OUT ANOTHER DASH, I FEEL GM HAS A SERIOUS DEFECT WITH THIS AND FEEL THIS A SERIOUS SAFETY ISSUE AS THE HEADLIGHTS ALL BUT GO OUT AT LOW SPEEDS, THE DEALERSHIP HERE HAS DONE ALL THAT GM WILL ALLOW THEM TO DO ACCORDING TO THEM. *JB

SPEEDOMETER FAULTY AND SHOWING WILDLY INACCURATE SPEEDS. WHEN DRIVING ON A HIGHWAY, THE SPEEDOMETER WILL RANGE FROM 10 MPH TO 120 MPH! WHILE CONDUCTING RESEARCH ONLINE, THIS APPEARS TO BE A MAJOR WIDESPREAD PROBLEM WITH GM TRUCKS AND THEY HAVE NOT TAKEN ANY ACTION TO CORRECT THIS DANGEROUS SITUATION. MY VEHICLE IS RECENTLY OUT OF WARRANTY AND THE REPAIR WILL COST OVER $600. *JB

THE SPEEDOMETER IN MY 2004 CHEVY TRAILBLAZER BEGAN TO SHOW THE WRONG SPEED AT ABOUT 45,000 MILES. THE NEEDLE WOULD INCREASE WITH SPEED AS IT SHOULD HAVE BUT WOULD NOT GO BACK DOWN AGAIN LIKE IT SHOULD. THEN IT QUIT WORKING ALTOGETHER AND THE NEEDLE JUST HANGS LIMP. WE HAD THE SPEEDOMETER DIAGNOSED AT ANOTHER FACILITY SINCE THIS OCCURRED AROUND THE HOLIDAYS AND GM DEALERS COULD NOT GET US IN. MY WIFE HAS BEEN COMMUTING 20-30 MILES DAILY HAVING NO IDEA HOW FAST SHE IS GOING BECAUSE GM REFUSES TO CORRECT THE PROBLEM. I HAVE FOUND HUNDREDS OF SIMILAR STORIES AFTER RESEARCHING IT ON THE INTERNET. EVERY PERSON I KNOW WITH A LARGE GM VEHICLE HAS HAD TO REPLACE IT BETWEEN 40,000 AND 50,000 MILES. THE FACILITY THAT DIAGNOSED THE PROBLEM SAID THAT THE SPEEDOMETER HEAD WAS STRIPPED AND THE DEALERSHIPS KNOW THE PRICE OF THIS PART OFF THE TOP OF THEIR HEADS, PRESUMABLY BECAUSE THEY REPLACE MANY OF THEM. *JB

THE GAS GAUGE DOES NOT WORK PROPERLY. I HAVE TALKED TO SEVERAL OWNERS OF TRAILBLAZERS AND THEY HAVE THE SAME PROBLEM. *JB

WHEN CHECKING MY BRAKES I NOTICED THAT THE INSIDE OF THE FRONT BRAKE ROTORS WHERE CORRODED AND RUSTY. THE VEHICLE IS A 2004 CHEVROLET TRAILBLAZER WITH 32,262 HIGHWAY MILES. APPROXIMATELY 25-30% OF THE INSIDE OF THE ROTOR WERE RUSTED AND HAD WORN DOWN THE BRAKE PAD. SO ONLY 70% OF THE INSIDE BRAKE PAD WAS BEING USED FOR BRAKING. THIS CAUSES THE BRAKE PADS TO WEAR UNEVENLY. APPEARS THAT THIS COULD BE SERIOUS IN AN EMERGENCY SITUATION. I CHECKED THE REAR ROTORS AND THEY ARE STARTING TO DO THE SAME BUT ONLY 1/2" ON THE OUTER EDGE OF BRAKE ROTOR IS RUSTED. I CHECKED THE RECALLS AND THERE WERE NONE FOR BRAKES. I CHECKED WITH CHEVY AND THEY ARE NOT AWARE OF ANY PROBLEMS. IN CHECKING WEBSITES, TRAILBLAZERCLUB AND TRAILVOY, OTHER PEOPLE HAVE HAD THE SAME OR SIMILAR ISSUE. I WOULD ASSUME THAT THERE IS A PROBLEM WITH THE METAL. *NM

2004 TRAILBLAZER LS WITH CODE P0455 DIAGNOSED WITH BROKEN/CRACKED SEAM ON FUEL TANK INLET NECK. VERY STRONG FUEL ODORS BOTH INSIDE AND OUTSIDE VEHICLE. CHEVY ACKNOWLEDGED THIS SAME PROBLEM WITH THE 2002 MODELS VIA CAMPAIGN #05012. THIS IS A SAFETY ISSUE, CAN LEAKING FUEL AND/OR BREATHING FUMES BE DEEMED AS SAFE? CHEVY NEEDS TO STEP UP AND PROACTIVELY FIX THE PROBLEM ON ALL TRAILBLAZER MODELS. I KNOW BOTH NHTSA AND CHEVY KNOW OF THIS PROBLEM ALREADY, SO ARE LIABLE IF NOTHING IS DONE. *JB
