1990 Jeep Cherokee

THE VECHILE BEGAN EXPERIENCING INTERMITTENT BRAKE FAILURE AT TRAVEL SPEEDS FROM 0-45MPH. DURING FAILURE, THE BRAKES WHEN APPLIED BEGIN TO SLOW THE VECHILE AND THEN PEDAL POWER IS LOST AND BRAKING ABILITY IS LOST. WHEN THE PEDAL IS RELEASED AND QUICKLY REDRPRESSED THE BRAKE POWER IS RESTORED.CHRYSLER MOTOR CORPORATION HAS BEEN CONTACTED ABOUT THE FAILURES. THE LOCAL DEALER PERFORMERMED A PROM TEST BUT COULD NOT DETERMINE THE NATURE OF THE FAILURE. THE LOCAL DEALER THEN SUGGESTED THAT THE MASTER CYLINDER WAS MOST LIKELY FAULTY, BUT REFUSED TO COVER IT UNDER A NHTSA RECALL. AN AUTOMOTIVE REPAIR SHOP REPLACED THE MASTER CYLINDER AT A COST OF $600. THE BRAKES FAILED AGAIN AFTER THE MASTER CYLINDER WAS REPLACE. THE FAILURE WAS REPORTED TO CHYSLER WHO SUGGESTED A SECOND DEALER TO CHECK THE ABS SYSTEM. THE SECOND DEALER PERFORMED A SERIES OF TEST TO THE VEHICLE BRAKING SYSTEM AND DETERMINED THAT THE ABS ACCUMULATOR PUMP ASSEMBLY WAS DEFECTIVE AND REPLACED IT AT A COST OF MORE THAN $319.00. THE DELEARSHIP REFUSED TO COVER THE REPAIR UNDER THE RECALL, AND THE LOCAL ZONE MANAGER REFUSED TO REPLACED THOSE PARTS OUTLINED IN THE NHTSA BULLETIN AS RELATED TO THIS TYPE OF FAILURE. THE LOCAL DEALER THEN ASSURED THAT THE REPAIR HAD CORRECTED THE FAILURE,AS DETERMINED BY HIS TEST. LESS THAN ONE WEEK AFTER THE SECOND REPAIR THE VECHILE AGAIN EXPERIENCED INTERMITTENT BRAKE FAILURE, OF THE SAME TYPE (LOSS OF BRAKING AND PEDAL POWER). THIS INCIDENT OCCURED ON AUGUST 30,1999. THE FAILURE WAS REPORTED TO THE DEALER, WHO SUGGESTED THAT THE VECHILE WAS UNSAFE TO DRIVE AND TOWED IT BACK FOR EXAMINATION. THE DEALER THEN PREFORMED TESTS AND REPORTED THAT THE BRAKE SENSORS WERE NOT PROPERLY CALIBRATED. THE DEALER WAS ASKED TO PERFORM THE REPAIRS AS MANDATED BY THE NHTSA. THE DEALER REFUSED TO PERFORM THE REPAIRS STATING THAT THE TEST DID NOT INDICATE THEY WERE NECESSARY. THE REPAIRS TO THE ABS BRAKE SENSORS WERE MADE AT A COST OF MORE THAN $149.00 PLUS TOWING. THE BRAKES HAVE SINCE FAILED AGAIN.*

MY VEHICLE HAD A STICKER INDICATING THAT THE TPS RECALL HAD BEEN COMPLETED PRIOR TO MY OWNERSHIP. I HAVE BEEN EXPERIENCING THE SAME PROBLEMS WITH THE TPS THAT CAUSED THE ORIGINAL RECALL ON THE PART. THE THROTTLE POSITION SENSOR HAS BEEN CAUSING INTERMITTENT HIGH ENGINE IDLE SPEEDS IMMEDIATELY AFTER STARTING THE ENGINE. THE IDLE CANNOT BE REDUCED BY TAPPING THE GAS PEDAL. THE RPMS CONTINUE TO INCREASE UNTIL I TURN MY VEHICLE OFF. I HAVE TO RESTART THE ENGINE ANYWHERE FROM 1 TO 6 TIMES BEFORE I CAN GET A NORMAL IDLE SPEED. I HAVE HAD SEVERAL INSTANCES WHERE THE IDLE SPEED HAS INCREASED WHEN I PLACED IT IN GEAR. IT HAS BEEN SO BAD THAT EVEN WITH MY FOOT COMPLETELY PRESSED ON THE BRAKE THE CAR STILL MOVES. THIS IS COMPLETELY UNSAFE AND I FEEL THAT THIS PART SHOULD BE REPLACED WITH ONE THAT ACTUALLY WORKS RIGHT. I AM WONDERING WHETHER THE ORIGINAL PART WAS ACTUALLY REPLACED WHEN THE RECALL WAS SUPPOSEDLY COMPLETED ON THIS VEHICLE OR WHETHER THE REPLACEMENT PART IS JUST AS FAULTY AND DANGEROUS AS THE ORIGINAL. I HAVE TAKEN MY JEEP TO SEVERAL MECHANICS FOR THIS AND A NUMBER OF OTHER PROBLEMS SINCE I PURCHASED IT A YEAR AGO. SO FAR EVERYONE I'VE TAKEN IT TO INCLUDING THE CERTIFIED JEEP DEALER/ SERVICE IN CHICO, CA., COURTESY MOTORS HAS TOLD ME THAT THE TPS IS MALFUNCTIONING AND CAUSING MY CAR TO ACCELERATE AT ITS OWN WILL. I TOOK MY CAR TO THE DEALER ON AUGUST 10, 1999 FOR A COMPLETE DIAGNOSTIC CHECK AND WAS TOLD THAT, AMONG A SERIOSLY LONG LIST OF OTHER THINGS, THIS PART WAS SERIOUSLY MALFUNCTIONING AND NEEDS TO BE REPLACED. ANOTHER ASC CERTIFIED MECHANIC AT GRAND AUTO IN CHICO TOLD ME TODAY THAT THIS PART SHOULD DEFINITELY BE REPLACEABLE UNDER THE ORIGINAL RECALL: NHTSA CAMPAIGN ID NUMBER: 90V177000 FOR REPLACEMENT OF THE FUEL INJECTION IDLE SPEED CONTROL UNIT. PLEASE CALL ME AT YOUR EARLIEST CONVENIENCE AT : (530)893-0684 HOME OR (530)218-4826 WORK . THANK YOU. SINCERELY, DEBORAH DAVIS
