Known issues on the 1986 P30. Two recalls are on the federal record for this year. One reaches the P30 through replacement oil filters that seal poorly, letting the engine lose its oil with fire as the possible end of it. The other is a left lower control arm that can crack and release the ball joint, ending steering control without warning. Three owner complaints are recorded, single entries on the fuel system, air bags and engine cooling. Lubrication, front suspension and fuel system work all carry their own specifications and torque values here.
