Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Exterior lighting

reports

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

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
