WENT TO GMC DEALER BECAUSE TRUCK HAS A TRANSMISSION OIL LEAK. TECHNICIAN NOTED THAT ALL THREE TRANSMISSION OIL COOLER LINE ARE LEAKING. ACCORDING TO INTERNET FORUM (HTTP://DIESELPLACE.COM/FORUM/SHOWTHREAD.PHP?T=202078), THIS IS A KNOW DEFECT ON THE 2006 SILVERADO AND SIERRA TRUCKS EQUIPPED WITH DIESEL ENGINE AND ALLISON AUTOMATIC TRANSMISSION. SEVERAL OWNERS HAVE HAD 2 OR MORE INCIDENTS. REPLACEMENT LINES ARE NO BETTER THAN THE ORIGINALS. I AM AN ENGINEER AND HAVE BEEN INVOLVED IN VEHICLE FIRE INVESTIGATIONS IN THE PAST, SOME WERE CAUSED BY LEAKING TRANSMISSION COOLER LINES DRIPPING ON HOT EXHAUST PIPES AND MANIFOLDS. THIS IS A POTENTIAL FIRE HAZARD! THIS REQUIRES A NEW DESIGN FOR THESE TRANSMISSION OIL COOLER LINES. *TR

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.
