AFTER PUTTING THE VEHICLE IN PARK AND PROCEEDING DOWN MY DRIVEWAY, THE ABS LIGHTS BEGAN FLASHING AND CHIMING ON THE DASH. I PUSHED THE BRAKE PEDAL AND IT WENT TO THE FLOOR. I STOPPED THE VEHICLE WITH THE EMERGENCY BRAKE. I GOT OUT OF THE VEHICLE AND NOTICED BRAKE FLUID DRIPPING UNDERNEATH THE TRUCK. I CRAWLED UNDER THE TRUCK AND FOUND THE LEFT REAR BRAKE LINE HAD CORRODED THROUGH JUST ABOVE THE FUEL TANK. I CALLED THE DEALER AND HE STATED THIS IS A KNOWN DEFECT FROM GM. HE SAID I NEEDED ALL BRAKE LINES REPLACED AND GM'S NEW PARTS HAD AN EXTRA COATING TO PREVENT CORROSION. IT COST ME $1100. THIS TYPE OF FAILURE SEEMS WAY TOO SOON FOR A TRUCK WITH 38,000 MILES. *TR
BRAKES FAILED TO STOP VEHICLE AT INTERSECTION/STOPLIGHT. BRAKE PEDAL WENT TO FLOOR AND STAYED THERE. DETERMINED THAT RUST THROUGH IN BRAKE LINE AT DRIVER SIDE OF FRAME, UNDER DRIVER SEAT, HAD ALLOWED FLUID LOSS. *TR

STARTED THE TRUCK AND APPLIED THE BRAKES TO SHIFT INTO GEAR AND THE BRAKE PEDAL WENT TO THE FLOOR. AFTER SEVERAL TIMES PRESSING THE PEDAL THERE WAS NO BRAKES AT ALL. THE TRUCK WAS TOWED TO THE DEALER WHERE I WAS INFORMED ALL THE BRAKE LINE WERE RUSTED AND NEEDED TO BE REPLACED AT A COST OF $1,300.00. THE TRUCK ONLY HAD 35,000 MILES ON IT. IF I HAD BEEN DRIVING, I AM SURE THIS WOULD HAVE LIKELY CAUSED A SERIOUS ACCIDENT. *TR
ALL EXHAUST MANIFOLD BOLTS ARE DEFECTIVE CAUSING THEM TO BREAK, WHEN THEY DO THE EXHAUST MANIFOLD SEPARATES FROM THE CYLINDER HEAD IN TURN DIRECTING ALL EMISSIONS FROM THE ENGINE INTO THE AIR, AND CABIN OF THE VEHICLE. THIS COULD CAUSE A FIRE IF NOT CORRECTED. ONE SPARK WOULD SET THE VEHICLE ON FIRE. *TR

Oct 6, 2008
MOBILITYWORKS IS RECALLING 133 MY 2005-2006 FORD E250, MY 2000, 2004-2006 E350, MY 2000, 2005 E450, MY 2005-2006 GMC 2500, GMC 3500, AND MY 2006 DODGE 2500 VANS EQUIPPED WITH RICON PLATFORM STYLE WHEELCHAIR LIFTS. THESE LIFTS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 403, "PLATFORM LIFT SYSTEMS FOR MOTOR VEHICLES." THE ANTI-STOW INTERLOCK MAY NOT DETECT THE PRESENCE OF A WHEELCHAIR OR MOBILITY AID USER. THE PRESSURE SENSING SWITCH THAT DETECTS THE PRESENCE OF WEIGHT ON THE PLATFORM WAS NOT ADJUSTED TO THE NECESSARY SENSITIVITY LEVEL. THE LIFT COULD STOW EVEN THOUGH SOMEONE OR SOMETHING IS STILL ON THE LIFT.
Consequence & remedy
Consequence: A LIFT OCCUPANT CAN BE INJURED SHOULD THE LIFT BEGIN TO STOW UNINTENTIONALLY.
Remedy: MOBILITYWORKS IS WORKING WITH RICON TO CORRECT THE WHEELCHAIR LIFTS FREE OF CHARGE (PLEASE SEE 07E097). OWNERS MAY CONTACT RICON AT 1-818-267-3000 OR MOBILITYWORKS AT 1-800-769-8267.
