NONE OF THE GAUGES IN THE INSTRUMENT CLUSTER WORK AT ALL. I HAD ALL OF THE STEPPER MOTORS, AND THE NEEDLES REPLACED. PARTS AND LABOR TOTALING $350.00, AND AS SOON AS I WAS DOWN THE STREET 4 OUT OF THE 6 DID NOT WORK,AND THESE REPAIRS WHERE JUST DONE IN 2015. NOW THE TWO THAT WERE WORKING JUST QUIT 3 DAYS AGO. I DO NOT KNOW HOW MUCH GAS I HAVE,I DO NOT KNOW HOW FAST I AM GOING, I DO NOT KNOW IF MY VEHICLE IS RUNNING HOT, OR IF THE BATTERY IS CHARGING. I HAVE NOTHING. THIS PROBLEM HAPPENS WHILE DRIVING EVERY TIME I START THE CAR. I BOUGHT THE VEHICLE USED AND THE GAUGES WERE BROKE WHEN I BOUGHT IT CAUSE I THOUGHT THAT I COULD GET THEM FIXED. I HAVE BEEN RESEARCHING THIS TOPIC ON TRAILBLAZERS IN GENERAL ON THE TRAILVOY FORUM, AND YOU WOULD BE SICK TO SEE HOW MANY OWNERS OF TRAILBLAZERS, OR TO READ THE STORIES. ALSO IT IS IRRESPONSIBLE TO LET PEOPLE DRIVE A VEHICLE UNDER THESE CONDITIONS, AND VERY, VERY, VERY UNSAFE. TO NOT KNOW ANYONE OF THESE THINGS COULD CAUSE THE VEHICLE TO STOP WHILE DRIVING RESULTING IN AN ACCIDENT. I WILL BE WAITING ALONG WITH THOUSANDS OF OTHERS FOR YOUR RECALL. J.S.

AS WE WERE DRIVING THE LOW BEAM LIGHTS COMPLETELY QUIT WORKING WE QUICKLY SWITCHED TO THE HIGH BEAM LIGHTS WHICH WORKED WITHOUT ANY PROBLEMS. AT THIS TIME THE INCIDENT WAS SEVERAL MONTHS AGO AND THE LOW BEAMS STILL DO NOT WORK AT ALL. THE TRAILBLAZER IS DESIGNED FOR THE LIGHTS TO WORK AT ALL TIMES AND THEY HAVE NEVER TURNED ON SINCE THE INCIDENT. WE HAVE HAD NO PROBLEMS WITH THE HIGH BEAMS AND ALL SIGNALS SEEM TO BE FUNCTIONAL. AS I HAVE RESEARCHED THE PROBLEM IT HAS COME TO MY ATTENTION THAT THIS IS A PROBLEM SEEN BY SEVERAL PEOPLE. I LOOK FORWARD TO HEARING FROM SOMEONE IN REGARDS TO THIS PROBLEM. ANY INFORMATION OR HELP IS GREATLY APPRECIATED. *TR

This PI communicates the requirement to provide a pico file to receive diagnostic assistance from TAC.

This Preliminary Information communication provides information to the technician about changing the tire and wheel size on vehicles. General Motors will only support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. Technician should not use the information that is provided by the antilock braking system tire size selection.

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

This service bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.

This bulletin provides information for use on a Product Assistance Claim (PAC), which is formerly known as a Product Allegation Resolution (PAR) claim.
