2012 Chevrolet Express Passenger 1500 VAN AWD

VEHICLE ROLLS WHILE IN PARK

WHEEL BEARINGS AND TIRES ARE BECAUSE OF RE-CALL ON THE TORG IS NOT ALIGN PUT BRAND NEW TIRES ON AND THE TIRES ARE ALREADY BALD IN THE FRONT.

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.

WE TOOK OUR VAN IN FOR A ROUTINE OIL CHANGE. OUR MECHANIC NOTICED THAT THE FUEL FILL CLAMP HAD BEEN RUBBING AGAINST THE BRAKE LINE THAT WAS STARTING AN INDENTATION FROM THE ONGOING RUBBING. HE HAD SEEN THIS HAPPEN IN ANOTHER 2012 CHEVY VAN, BUT IN THAT CASE, THE RUBBING OF THE FUEL CLAMP, RESULTED IN A BRAKE IN THE LINE, LEAKING OF ALL BRAKE FLUID, CAUSING TOTAL LOSS OF BRAKING FUNCTION & ABILITY TO STOP VEHICLE. OUR MECHANIC ADVISED US TO GO TO THE NEAREST CHEVY SERVICE CENTER, WHERE THEY COULD ORDER THE PROPER PARTS AND FIX THE ISSUE BEFORE SOMETHING TRAGIC (LIKE TOTAL LOSS OF BRAKE FUNCTION) COULD HAPPEN. I TRULY BELIEVE THAT THIS MALFUNCTION IS NOT AN ISOLATED CASE AND STEPS SHOULD BE TAKEN FOR AN IMMEDIATE RECALL TO CHECK THESE 2012 VANS.

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.

ENGINE WAS AT IDLE HAD PULLED INTO GAS STATION . ALARMS WENT OFF CHECK ENGINE LIGHT CAME ON, STABLE TRACK ERROR, MULTIPLE TONES. AFTER 20 SECONDS ENGINE STALLED. WOULD NOT CRANK. AFTER TALKING TO PEOPLE AND COUPLE TRIES FIX TOOK TO DEALERSHIP AS IT WAS DIAGNOSED TO BE THE ENGINE CONTROL MODULE SHORTED. I HAD GONE THRU RAIN EARLIER AND A COUPLE STORMS PASSED THRU WHILE AT STATION AND EATING. DEALER REPLACED ENGINE CONTROL MODULE AND PROGRAMMED IT. THIS COULD OF HAPPENED WHILE DRIVING AND WOULD OF LOST ENGINE POWER AND POWER STEERING. SINCE JUST MODULE REPLACED AND BEN TOLD IT IS KNOW TO SHORT OUT WHEN WET IT COULD HAPPEN AGAIN.

TL* THE CONTACT OWNS A 2012 CHEVROLET EXPRESS. WHEN THE BRAKES WERE DEPRESSED AND RELEASED, THE VEHICLE BEGAN TO SHAKE VIOLENTLY. THE CONTACT MENTIONED THAT THE STABILITRAK ACTIVATED INDEPENDENTLY AFTER BEING TURNED OFF WITHOUT WARNING. THE VEHICLE WAS TAKEN TO DEALER. THE TECHNICIAN WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 47,000.

DRIVER'S SEAT BELT REEL SEIZED WHILE THE VEHICLE WAS PARKED SO THE BELT COULD NOT BE EXTENDED AND BUCKLED. THE OPERATOR WAS NOT ABLE TO WEAR THE SEAT BELT AS REQUIRED BY LAW. VEHICLE WAS BROUGHT TO THE CHEVROLET DEALER AND REPAIRED UNDER TSB 05-09-40-002G TODAY, A SECOND VEHICLE OF THE SAME MAKE/MODEL 2014 MODEL YEAR EXPERIENCED THE SAME PROBLEM.
