Known issues on the 1993 911. Two recalls are on federal record for this model year. The first covers the steering column: a part of the upper universal joint cracked during manufacturing, which produces noise and free play in the steering and, left uncorrected, can result in loss of steering control. The second covers the hydraulic brake pressure reduction valve, which can slow the rate of pressure reduction and cause the rear wheels to lock up even with the anti-lock system active, risking loss of vehicle control. Owners have filed 0 complaints for the year. The factory diagnostic and repair procedures behind both systems are here.
