A PROBLEM RELATING TO THE FRONT EXHAUST PIPE BRACKET ATTACHMENT COULD CAUSE LEAKING OF TRANSMISSION OIL. TRANSMISSION COULD LOCK UP DUE TO LACK OF PROPER OIL LUBRICATION.
Manufacturer remedy
DEALER WILL REPLACE THE EXISTING EXHAUST PIPE BRACKET WITH ONE THAT ATTACHES TO THE SIDE OF THE TRANSMISSION. THE REAR DIFFERENTIAL COVER GASKET WILL ALSO BE REPLACED, USING SCREWS INSTEAD OF STUDS.
UNDER CERTAIN CONDITIONS SUCH AS AMBIENT HUMIDITY AND VEHICLE PRE-CONDITIONING BY REPEATED COLD START, AND SHORT TRIP DRIVING CYCLES IN COMBINATION WITH SUB-ZERO TEMPERATURES, THERE EXISTS THE POSSIBILITY FOR ICE TO FORM IN THE THROTTLE HOUSING AND TEMPORARILY IMPEDE FULL CLOSURE OF THE THROTTLE PLATE WHEN THE ACCELERATOR IS RELEASED. THIS ICE BUILD-UP IN THE THROTTLE HOUSING MAY CAUSE HESITATION IN VEHICLE DECELERATION AND INCREASED STOPPING DISTANCES.
Manufacturer remedy
THE DEALER WILL MODIFY THE ENGINE INTAKE SYSTEM TO FURTHER IMPROVE PREHEATING OF INCOMING AIR IN COLD WEATHER. THIS WILL BE DONE FREE OF CHARGE.

Defect description
INSUFFICIENT CLEARANCE MAY EXIST BETWEEN THE FUEL TANK VENT TUBE AND VEHICLE FLOORPAN WHERE THE TUBE PROJECTS THROUGH AN ACCESS HOLE INTO THE TOOL COMPARTMENT UNDER THE TRUNK FLOOR. SHOULD THE TUBE CONTACT THE LOWER EDGE OF THIS OPENING, IT COULD BECOME DAMAGED AND FAIL AT THE POINT WHERE IT IS SOLDERED TO THE FUEL TANK. FUEL LEAKAGE COULD RESULT, ESPECIALLY WHEN THE TANK IS NEARLY OR COMPLETELY FULL.
Manufacturer remedy
DEALER WILL ENLARGE THE ACCESS HOLE IN THE FLOORPAN TO ENSURE PROPER CLEARANCE. IF THE VENT TUBE IS DAMAGED, IT WILL BE REPAIRED.
INSUFFICIENT CLEARANCE BETWEEN THE AIR/FUEL MIXING REGULATOR AND THE THROTTLE HOUSING COULD ALLOW THE DECEL SOLENOID LINK ARM ON THE THROTTLE TO CONTACT THE MIXING REGULATOR UNDER CERTAIN EXTREME DRIVING CONDITIONS. THIS WOULD CAUSE THE ENGINE TO ROCK TO THE LEFT ON ITS MOUNTING. FULLY DEPRESSING THE ACCELERATOR WHILE MAKING A SHARP RIGHT TURN AT MODERATE TO HIGH SPEEDS COULD CAUSE SUCH A CONTACT TO OCCUR. FURTHERMORE, MOVEMENT OF THE THROTTLE PLATE MAY MOMENTARILY BE RESTRICTED DURING THE TIME OF CONTACT BETWEEN THE LINK ARM AND MIXING REGULATOR.
Manufacturer remedy
THE DEALER WILL REPLACE THE LINK ARM WITH A MODIFIED ONE TO ENSURE SUFFICIENT CLEARANCE TO THE MIXING REGULATOR UNDER ALL DRIVING CONDITIONS. THE POSITION OF THE DECEL SOLENOID MAY ALSO BE READJUSTED IF FOUND NECESSARY.
THERE IS A POSSIBILITY THAT THE WEBBING NEAR THE METAL TONGUE OF THE LEFT HALF OF THE CENTER REAR SEAT BELT MAY HAVE BEEN IMPROPERLY SEWN TOGETHER.
Manufacturer remedy
DEALER WILL INSPECT THE CENTER REAR SEAT BELT AND, IF NECESSARY, REPLACE IT.
