Defect
GM IS RECALLING 1,880 MODEL YEAR 2007 CHEVROLET KODIAK AND T-SERIES, GMC TOPKICK AND T-SERIES, AND ISUZU F-SERIES AND H-SERIES PASSENGER VEHICLES EQUIPPED WITH 7.8L DIESEL ENGINE. THE AIR COMPRESSOR IN SOME OF THESE VEHICLES MAY NOT BUILD ENOUGH AIR PRESSURE TO SUPPORT THE AIR BRAKE SYSTEM. IF THIS CONDITION WERE TO OCCUR WHILE THE VEHICLES WAS STATIONARY (BRAKES APPLIED), THE AIR BRAKES WOULD REMAIN APPLIED AND PREVENT THE VEHICLE FROM MOVING.
Safety Risk
IF THE DRIVER IGNORES THESE WARNINGS AND CONTINUES TO DRIVE THE VEHICLE, AND IF THERE WAS A CONTINUED LOSS OF PRESSURE, THE REAR SPRING PARKING BRAKES WOULD AUTOMATICALLY APPLY, PREVENTING THE TRUCK FROM BEING DRIVEN.
Remedy
DEALERS WILL INSPECT THE AIR COMPRESSOR FOR ITS ABILITY TO BUILD AIR PRESSURE, AND EITHER MODIFY THE AIR COMPRESSOR BY ELIMINATION OF THE SUPPRESSION VALVE OR REPLACE THE AIR COMPRESSOR ASSEMBLY FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN DURING AUGUST 2009. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, ISUZU AT 1-800-255-6727 OR AT WWW.GMOWNERCENTER.COM.
