NHTSA lists 1 safety recall and 1 owner complaint for the 1998 Toyota Supra. Most complaints involve engine and engine cooling (1). The EPA rates it 18–19 mpg combined.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 1998-2000 RAV4, 1998-1999 RAV4 EV and Celica and 1997-1998 Supra vehicles. These vehicles were equipped with Non-Azide Driver air bag Inflators (NADI) and do not contain phase stabilized ammonium nitrate (PSAN) propellant. Due to a manufacturing issue, the NADI inflators may absorb moisture, causing the inflators to rupture or the air bag cushion to underinflate.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“VEHICLE STARTED OVERHEATING WHILE DRIVING. HEAD GASKET HAD BLOWN. DEALER CONTACTED. DEALER SAID THIS WAS A COMMON PROBLEM WITH THIS TYPE OF VEHICLE.*AK”
