1. Filed Aug 6, 2026Failure Aug 4, 2026Oshawa ON, ARElectrical system, Service brakes

   ABS Valve Body / Pump Harness chafed through brake hydraulic line near transmission crossmember. This resulted in a hydraulic leak and loss of brake pedal feel / partial loss of brakes. Fortunately failure occurred in the driveway--I had 4500 Lbs of sailboat trailer hitched to the van and was about to go on a long trip. Design issue. Wiring harness should not be located so as to chafe on hydraulic lines. This is not the first chafe related failure on this vehicle.

3. Filed Apr 23, 2025Failure Apr 22, 2025Downingtown, PAFuel/propulsion system

   Vehicle is upfitted as a school bus. Forward fuel tank strap failed in operation. Our company operates more than 100 of these vehicles and we experience a failure of fuel tank straps at a rate of about one vehicle per month. If the 2nd strap would also fail the gasoline tank would become dislodged and present a re hazard. This is even more critical as these vehicles are carrying students as a school bus. We perform visual inspections of the straps at 6 month intervals (per Pennsylvania these vehicles are subject to Semi-Annual State Inspection). There were no symptoms of the problem before this failure. There are never symptoms of the problem.

   I MANAGE A FLEET OF 53 SCHOOL BUSES, MODEL YEARS RANGING FROM 2008 TO 2015. I HAVE NOTICED A TREND WITH THE HYDRO BOOSTERS AND MASTER CYLINDERS, THEY TEND TO LEAK INTERNALLY ON THESE GM VEHICLES SOME HAVE BEGUN TO LEAK AS EARLY AS 30,000 MILES. I EXPECT TO HAVE TO REPLACE ALL OF THESE COMPONENTS, ON EVERY BUS IN THE NEAR FUTURE. AS THE FLEET AGES THE TREND IS GETTING INCREASINGLY WORSE. I BELIEVE THIS IS A DANGEROUS SITUATION BECAUSE I AM VIGILANT WITH KEEPING UP ON THIS ISSUE, HOWEVER I AM NOT SURE THAT THE GENERAL PUBLIC WILL HAVE THE SAME UNDERSTANDING ABOUT THE DANGER OF THIS DESIGN FLAW. I HAVE HAD BUSES COME IN BLEEDING BRAKE FLUID OR HYDRAULIC FLUID.

8. Filed Sep 29, 2015Failure Sep 1, 2015100,000 milesCorydon, INEngine, Power train

   THE ENGINE WILL GO TO LOW POWER AND NOT GO MORE THAN 30 MPH WITHOUT WARNING. THIS IS AN AMBULANCE CHASSIS AND IS A KNOW PROBLEM GM HAS NOT ADDRESSED YET IN THE 2012 AND 2013 CHASSIS. IT CAN DO THIS ON HWYS WITH SPEED LIMITS OF 55, 65, 70 MPH SUDDENLY WHICH COULD CAUSE AN ACCIDENT AS NO STOP LIGHTS GIVE ANY WARNING AND YOU CAN'T SPEED UP ANYTIME IN POOR VISIBILITY OR AT ANYTIME. NOT ONLY IS IT BAD FOR THE INJURED OR ILL PATIENT IT COULD CAUSE AN ACCIDENT AND INJURY OTHERS. GM HAS FIXED THIS ON THE 2014 AND NEWER MODELS BUT NOT 12 &13. THIS IS NOT JUST OUR ONE UNIT THIS IS 2012 AND 2013 CHEVY DIESELS AMBULANCE ALL OVER THE US. WE HAVE FOUR UNITS THAT IT CAN HAPPEN TO AND TWO THAT IS HAS WITH PATIENTS. I HAVE CONTACTED THE EPA, GM, AND OUR INDIANA STATE SENATORS TRYING TO GET THIS DANGEROUS SITUATION TAKEN CARE OF IN THE LAST FEW DAYS. I AM ASKING ANYONE WHO WILL LISTEN TO HELP PUSH GM FOR A FIX.
