Limited data — recalls on file

NCAP overall
2 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
PERFORATION OF THE FUEL TANK OR ATTACHED FUEL FEED PIPE DUE TO CORROSION OF THE TANK OR FUEL FEED PIPE MATERIALS.
Consequence
THIS CONDITION COULD ALLOW FUEL TO LEAK FROM THE FUELTANK AND ULTIMATELY RESULT IN A FIRE WITHOUT PRIOR WARNING. SUCH A FIRE COULDSPREAD TO THE PASSENGER COMPARTMENT.
Remedy
REPLACE GAS TANK WITH NEW CORROSION RESISTANT TANK.
Defect
THE POSITIVE CRANKCASE VENTILATION VALVE MAY PROVIDE INADEQUATE AIR FLOW UNDER LOW ENGINE LOAD CONDITIONS.
Consequence
THIS CONDITION CAN ALLOW WATER/OIL MIXTURE TO BUILD UPIN THE HOSE FROM THE OIL SEPARATOR TO THE AIR INLET DUCT. AFTER THE ENGINE ISSTOPPED, THIS WATER/OIL MIXTURE CAN, UNDER COLD WEATHER CONDITIONS, FREEZE ANDCOMPLETELY BLOCK THE OIL SEPARATOR AIR DUCT HOSE. THIS BLOCKAGE WILL RESULT ININCREASED PRESSURE WITHIN THE CRANKCASE. THIS CAN CAUSE OIL LEAKS. IF ASUFFICIENT QUANTITY OF OIL CAME IN CONTACT WITH THE HOT EXHAUST SYSTEM AN ENGINECOMPARTMENT FIRE COULD RESULT WITHOUT PRIOR WARNING.
Remedy
THE PCV VALVE WILL BE REPLACED WITH A NEW VALVE.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 2 recalls should be verified as completed.
Yes — NHTSA lists 2 recall campaigns affecting the 1988 Isuzu I-Mark. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
