NHTSA lists 2 safety recalls and 122 owner complaints for the 1996 Cadillac Seville. Most complaints involve electrical system (24) and engine and engine cooling (24). The EPA rates it 18 mpg combined.
SOME PASSENGER VEHICLES EQUIPPED WITH 4.0L V8 ENGINES HAVE A CONDITION IN WHICH THE NYLON TUBING USED IN THE FUEL RAIL CONSTRUCTION MAY DEGRADE AND CRACK. ADDITIONALLY, THE 1995 MODEL YEAR USES A UNIQUE UNDERHOOD FUEL RETURN LINE THAT MAY CRACK. CRACKING OF THE FUEL RAIL OR RETURN LINE TUBING CAN RESULT IN A FUEL LEAK INTO THE ENGINE COMPARTMENT.
THE ANALOG INSTRUMENT PANEL CLUSTER ON THESE VEHICLES COULD HAVE AN INTERNAL SHORT CIRCUIT DISRUPTING THE PASS KEY SYSTEM, CAUSING FAILURE OF THE INSTRUMENT PANEL GAUGES AND TELL-TALES, AND A POSSIBLE NO-START CONDITION. THIS DOES NOT CONFORM TO THE REQUIREMENTS OF FMVSS NO. 101, "CONTROLS AND DISPLAYS;" NO. 108, "LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT;" AND NO. 208, "OCCUPANT CRASH PROTECTION."
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
