Known issues on the 1992 P30. Two recalls sit on the federal record here, both involving replacement filters that seal badly at their connections — one letting the engine lose oil, the other leaking gasoline into a place where heat can find it, with fire the risk in each case. Owners have logged four complaints, spread singly across the electrical system, steering and service brakes. Circuit tracing, steering gear inspection and brake hydraulic service each have their own diagnostic sequences and torque figures in this manual.
