Power steering cuts out or goes heavy

The Office of Defects Investigation (ODI) analyzed complaint data provided by Chrysler as well as complaints submitted to ODI from consumers. ODI's analysis identified a total of 24 unique reports indicating power steering hose blow-offs resulting from a dislodged power steering cooler turbulator fin in some early production vehicles.According to Chrysler, a dislodged fin can occur when the turbulator is inserted into the power steering cooler or loaded into the assembly machine.A dislodged fin may block the flow of power steering fluid creating excess back-pressure in the power steering system leading to the possibility of a return hose blow-off.Chrysler and its power steering cooler supplier, Dana, modified the cooler assembly process to address factors that may contribute to hose blow-offs. The redesigned turbulator assembly stations were completely implemented in production by April 2012.During PE12-020, Chrysler identified occurrences where the power steering return hose may blow-off at the power steering cooler.This is a condition that typically occurs early in the life of the vehicle with 65% occurring at less than 2,000 miles and 96% occurring with less than 8,000 miles. The data also shows that 88% of the conditions occurred with less than 4 months in service. Over 50% of the blow-off complaints occurred on vehicles with build dates between November 22, 2011 and December 23, 2011. None of the conditions occurred with more than 12,000 miles or 7 months in service. Chr

ALLEGED THAT THE VISCOUS COUPLING IN THE TRANSFER CASE OF HIS 1993 GRAND CHEROKEE VEHICLE FAILED WHICH AFFECTED STEERING, BRAKING AND STARTING OF THE VEHICLE.

ON JANUARY 25, 1994 CHRYSLER CONDUCTED A SAFETY RECALL TO CORRECT THE STEERING SHAFT ASSEMBLY IN MODEL YEAR 1993 GRAND CHEROKEE AND GRAND WAGONEER.THE RECALL POPULATION WAS 115,000 VEHICLES.THE DEFECT WAS THE MOLDED PLASTIC PIN WHICH CONNECTS THE UPPER STEERING COLUMN SHAFT AND THE LOWER STEERING COLUMN SHAFT WHICH MAY HAVE BEEN SHEARED/DAMAGED PRIOR TO THE INSTALLATION OF THE STEERING ASSEMBLY INTO THE VEHILE.IF THIS OCCURRED, THE UPPER STEERING SHAFT WILL SEPARATE FROM THE LOWER STEERING SHAFT CAUSING COMPLETE LOSS OF THE STEERING CONTROL OF THE VEHICLE.AS A REMEDY, CHRYSLER INSTALLED A RESTRAINING SLEEVE TO LIMIT THE AMOUNT OF STEERING SHAFT MOVEMENT AVAILABLE.
