NHTSA Complaint #10266523 — 2006 CHEVROLET TRAILBLAZER EXT

2006 TRAILBLAZER EXT, 12/08 EXITING FREEWAY ONTO 50 MPH ROADWAY AND ACCELERATING FROM STOP SIGN AT TOP OF RAMP, WHEN ENGINE LOST POWER AND SLOWED TO A STOP, WITH ENGINE RUNNING AND CHECK ENGINE LIGHT ON, ALL AT ONCE. ALMOST BROADSIDED ON DRIVERS DOOR BY APPROACHING TRAFFIC.. ONSTAR SAID IN WAS A THROTTLE VALVE BODY ISSUE AND HAD IT TOWED TO DEALER FOR NIGHT DROP OFF. NEXT MORNING NO CODE FOUND, BUT THEY CLEANED THE THROTTLE BODY VALVE ASSEMBLY AND LINKAGE. NO CHARGE FOR DIAGNOSTICS OR CLEANING! 4/21/09, 3000 MILES LATER, THE CHECK ENGINE LIGHT COMES ON WITH VEHICLE OPERATING NORMALLY. ONSTAR SAYS GET IT TO A DEALER IN ONE DAY, ITS THE THROTTLE VALVE BODY AND LINKAGE. $100 FOR DIAGNOSIS ALREADY SENT TO DEALER BY ONSTAR. DEALER SAYS THE ELECTRONIC RADIATOR FAN CLUTCH IS NOT ENGAGING AND ENGINE RUNS COLD, TECHNICIAN SAID NO, IT RUNS HOT, NEITHER OF WHICH WAS OCCURRING. DEALER SAYS THEY HAVE A HISTORY CODE FOR THROTTLE VALVE AND LINKAGE, SO ITS OBVIOUSLY CARBONED UP AND THOUGH ITS NOT LISTED ANYWHERE IN OWNERS MANUAL FOR SUCH SERVICE, THEY SAY ITS A MAINTAINING ISSUE, DON'T VOID YOUR WARRANTY. IF YOU DON'T LET US DO IT FOR $149, IT'S $52 FOR READING THE HISTORY CODE. THEY REMOVE THE AIR CLEANER DUCT AND THEY TRY TO SELL ME A BILL OF GOODS, I.E. LOOK AT THE CARBON BUILD UP, WHICH IS NOTHING MORE THAN A VERY THIN, THIN COATING OF DARKENED OIL VAPOR RESIDUE WHICH IS PULLED IN FROM THE CRANK CASE VENT HOSE ATTACHED BELOW THE INTAKE HORN, AFTER HE AIR FILTER AND SENSOR. RIP OFF! THE VEHICLE RAN PERFECT BUT FOR THE CHECK ENGINE LIGHT, NEVER RAN COOL OR OVER HEATED AND WAS GETTING GOOD MILEAGE. I LET THEM REPLACE THE $600 PLUS FAN FOR THE $100 DIAGNOSTIC FEE. TO KEEP FROM VOIDING MY WARRANTY, I HAD TO SPEND THE $149 FOR AN OLD HISTORY CODE, TO PROVE THAT I MAINTAINED THE VEHICLE PER DEALER RECOMMENDATIONS. RIP OFF !!! *TR
