Each component in detail
What the reports in each category say, in the owners' own words
Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
My first complaint is that headlights, low beam, would not work. Only high beams worked. The issue stopped, unexplainable, on its own, has not occurred again. The 2nd complaint is the radio volume would 'slip' as if there were a loose wire to the speakers, and loss of sound became more frequent and for longer periods of time, eventually all sound stopped, it has not been fixed, as of yet. 3rd complaint, a brand new battery, in under a year of use, went completely dead, without any visible explanation. When an attempt to jump start the vehicle the cables from another cars battery were touched at my cars battery, it sparked, indicating to the person performing the task, there is a 'short' somewhere in the wiring system. I drive this vehicle less than 3000 miles per year, and use it sporadically with my second vehicle to keep the batteries active. I cannot explain why these issues are occurring but thought it important to mention them to other possible victims with the same issues.

THE HEADLIGHTS HAVE FAILED. ALL THE LIGHTS BLINK WHILE YOU RIDE ALONG. THE TWO BACK DOORS WILL NOT LOCK OR UNLOCK AND THE FRONT DOORS ARE STARTING TO NOT LOCK OR UNLOCK PROPERLY. THE ITEMS THAT LET YOU KNOW WHEN A TIRE IS LOW IN AIR ARE FAILING. THE LAST ONE COSTING OVER $100 TO FIX. I AM GETTING VERY UPSET WITH THE ELECTRIC PARTS IN THIS TRAILBLAZER. THIS HAS BEEN GOING ON SINCE PURCHASE. AS A PHOTO I CAN SEND YOU A PHOTO OF THE VEHICLE.

THE ENGINE LIGHTS COME ON, THEN THE CAR STARTS CHUGGING AND SHUDDERING AND SOUNDS AND FEELS AS IF IT WILL SHUT DOWN. I AM NOT ABLE TO ACCELERATE. THIS IS A SERIOUS SAFETY RISK IN TRAFFIC, ESPECIALLY IF DRIVING ON THE INTERSTATE. THE CAR WILL NOT MOVE AT ANYTHING OVER 20 MPH, IF IT EVEN ACCELERATES AT ALL. I USUALLY END UP COASTING TO THE SIDE OF THE ROAD AND SHUTTING THE ENGINE DOWN. I LET IT SIT AND TURN IT BACK ON AND IT MAY OR MAY NOT LET ME GO AGAIN. *TR

CRACKED EXHAUST MANIFOLD
AS I WAS DRIVING IN MY YARD I HAPPENED TO BUMP THE IGNITION KEY AND THE MOTOR CUT OUT AND DIED. THIS CAUSED ME TO NOT BE ABLE TO TURN AND AVOID BUMPING A POST CAUSING SOME BODY DAMAGE, BUT I WAS ABLE TO AVOID HITTING MY FRIEND IN THE YARD BECAUSE HE HAD MOVED FROM BY THE POST A MINUTE EARLIER. I HAVE HAD ONE MORE TIME WITH THIS PROBLEM, BUT NOT HAD A PROBLEM SINCE, BUT I AM NOW EXPERIENCING AN OCCASIONAL ROUGH RUNNING ENGINE. COULD THIS IGNITION SWITCH ON THIS YEAR VEHICLE NEED TO BE RECALLED ALSO?

I HAVE BEEN SEEING THAT WHEN COMING TO A STOP MY VEHICLES IDLE STAYS UP WHEN IT SHOULD BE KICKING DOWN TO A LOWER RPM TO SLOW THE VEHICLE. I HAVE TO SMASH ON THE BRAKE PEDAL AT TIMES B/C IT FEELS LIKE THE TRUCK ISN'T STOPPING AND THE ENGINE RPMS STAY HIGH. I HEAR THIS IS A VERY COMMON PROBLEM AND HEARD THE FACTORY IS DOING NOTHING ABOUT IT. IM YET TO BRING IT IN FOR THIS CONCERN BUT WHY BOTHER IF OTHERS ARE BEING BRUSHED OFF BY THE DEALERS. I GUESS GM WILL ONLY STEP IN WHEN SOMEONE GETS HURTS OR EVEN DIES FROM THIS. *TR
