NHTSA Complaint #10852852 — 2000 JEEP GRAND CHEROKEE

FIRST: I HAD PURCHASED THIS VEHICLE USED WITH APPROX. 110,000 MILES ON ODOMETER. STEERING WHEEL VIOLENTLY SHAKES ON MODERATE TO HEAVY BRAKING AS WELL AS MODERATE SHAKING UPON DECELERATION ON HIGHWAY SURFACES AS WELL AS INTERMENT CLUNKING FROM FRONTAL SUSPENSION AREA UNDER SIMILAR CONDITIONS. THE STEERING WHEEL MAY BE POINTED STRAIGHT AHEAD OR AT A SLIGHT LEFT OR RIGHT POSITION. THERE ARE TIMES WHEN THE SHAKING, UNDER THE ABOVE CONDITIONS, IS VERY SLIGHT OR NONEXISTENT AT ALL. I BELIEVE IT IS IN THE FRONT STEERING LINKAGE/SUSPENSION AND NOT THE BRAKES. I HAVE PERSONALLY INSPECTED THE COMPONENTS MENTIONED ABOVE AS I HAVE MOPAR EXPERIENCE IN THE PAST AS A TECHNICIAN. I HAVE ALSO HAD A SECOND OPINION FROM AN INDEPENDENT TECHNICIAN WELL VERSED IN JEEP TECHNOLOGY. SECOND; I ALSO HAVE A PROBLEM WITH THE OIL PRESSURE BEING ERRATIC WHEN WARMED UP AND EITHER STATIONARY OR IN MOTION. I HAVE REPLACED THE OIL PRESSURE SENDING UNIT AND PERFORMED MOPAR DIAGNOSTICS ON THE CLUSTER AS MENTIONED IN THE SHOP MANUAL TO NO AVAIL ON THIS 4.0L ENGINE WITH AUTOMATIC TRANSMISSION.THE GAUGE READS WELL WHEN COLD BUT WHEN WARMED UP IT WILL DROP TO ZERO WITH THE GAUGE ALARM WARNING ME OF THE ACTION. THEN MOVING ERRATICALLY BETWEEN THE 40LB MARKER AND ZERO PRESSURE WHILE IN MOTION OR STATIONARY. I AND A FEW TECHNICIANS ARE HAVING DIFFICULTY DETERMINING WHERE THE PROBLEM IS GENERATED. ON A NOTE, THERE IS A SLIGHT CONSISTENT TICKING NOISE SUCH AS A VALVE LIFTER OR ROCKER ARM COMING FROM THE ENGINE, WARM OR COLD, STATIONARY OR IN MOTION. IT OCCURRED WHEN I PURCHASED THE VEHICLE AND IS STILL OCCURRING TODAY. THANK YOU FOR ANY CONSIDERATION THAT YOU MAY PROVIDE TO ME AS THIS IS MY ONLY MEANS OF TRANSPORTATION AND I AM HANDICAPPED.
