BRAKES COMPLETELY FAILED. TRAVELING 35 MPH, I HAD TO BRAKE SUDDENLY AND THE PEDAL SUNK TO THE FLOOR. HAD MINOR RESISTANCE, THEN JUST COMPLETELY GAVE WAY. NO BRAKES! WAS ABLE TO AVOID AN INCIDENT BY VEERING INTO THE ONCOMING LANE THAT WAS LUCKILY VACANT. TURNED ONTO A SIDE STREET TO SAFELY ROLL TO A STOP. TOO SCARED TO DRIVE IT THE REMAINING 1.5 MILES HOME, I HAVE IT TOWED TO A SHOP. ADVISED THAT ALL BRAKE LINES NEED TO BE REPLACED, THIS IS A COMMON PROBLEM WITH GMC THAT HE HAS SEEN A DOZEN TIMES. THE BRAKE LINES CORRODE, AND EVENTUALLY BURST. ABSURD! TO THINK THIS COULD OF HAPPENED ON A FAMILY ROAD TRIP AT 65MPH... I WILL BUYING A VEHICLE OUTSIDE OF GMC AND THEIR UMBRELLA OF POORLY MADE VEHICLES- ASAP!

TIRES WERE PURCHASED SEPT. 25, 2009 AND NOW HAVE EXTENSIVE WEATHER CRACKING. COSTCO REFUSED TO REPLACE THE TIRES WHEN I REPORTED THE QUALITY DEFECT IN AUGUST, 2014, JUST 59 MONTHS AFTER PURCHASE. I HAVE APPEALED THAT DECISION AND EXPECT TO FIND OUT TOMORROW IF THEY WILL MAKE GOOD ON THE DEFECTIVE TIRES. THEY CLAIM THAT ALTHOUGH THERE IS WEATHER CRACKING THAT THE TIRES ARE SAFE. I DOUBT THEY WOULD USE CRACKED TIRES LIKE THAT ON THE VEHICLE CARRYING THEIR OWN FAMILY. *TR

THE ANTILOCK BRAKING SYSTEM ACTIVATES MOST EVERY TIME THE BRAKES ARE APPLIED, ESPECIALLY IF THE BRAKES ARE APPLIED WHILE THE WHEELS ARE TURNED. THIS CAUSES EXTENDED BRAKING DISTANCES. *TR

I WAS DRIVING ON ROUTE 287 NORTH, IN MORRISTOWN, NJ WHEN THE CAR IN FRONT OF ME STOPPED SHORT AND I NEEDED TO APPLY MY BRAKES. WHEN I USED MY BRAKE PEDAL, THE PEDAL WENT ALL THE WAY DOWN TO THE FLOOR AND I COULD NOT STOP. I WAS ABLE TO AVOID THE VEHICLE IN FRONT OF ME, AND I SWERVED TO AVOID OTHER CARS. I ROLLED TO A STOP ON THE GRASS SHOULDER OF THE HIGHWAY AND FOUND A PUDDLE OF BRAKE FLUID UNDER THE CAR. AFTER INSPECTION OF THE BRAKES DONE BY A CERTIFIED GM MECHANIC, HE FOUND THAT ALL OF THE BRAKE LINES IN THE CAR BURST OPEN DUE TO HEAVY CORROSION LEADING TO THE COMPLETE FAILURE OF THE SYSTEM. HIS RECOMMENDATION WAS TO REPLACE ALL BRAKE LINES IN THE VEHICLE AS NONE OF THEM WERE ABLE TO BE SALVAGED. *TR

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

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.

This service bulletin provides information for dealers/technicians on Service Programming System (SPS) Error Codes E4398, E4399, E4401, E4403, M4404, M4413, M6954, M6955, E4414, E4423, E4491, E4492, or E6961 and resolution information.
