2000 Toyota Camry Solara

AM EXPERIENCING SLUDGE BUILD UP IN THE ENGINE OF MY 2000 TOYOTA CAMRY SOLARA. THIS VEHICLE WAS A PREVIOUSLY OWNED WHEN I PURCHASED IT ON MARCH 17, 2016. AT TIME OF PURCHASE I REQUESTED A CARFAX REPORT. MY CHOICE TO PURCHASE WAS MADE UPON REPORT DETAILS I.E. REPAIR & MAINTENANCE RECORDS, INCLUDING ROUTINE OIL CHANGES. THE CARFAX REPORT SPECIFIED ALL PREVENTATIVE MAINTENANCE HAD BEEN APPLIED TO THIS VEHICLE AND WAS UP TO DATE. THERE WERE NO KNOWN MANUFACTURE RECALLS AND/OR ISSUES ON THIS VEHICLE. AT THE TIME OF PURCHASE I WAS UNAWARE OF ANY TROUBLESOME ISSUES ON THIS MAKE & MODEL, NOR WITH ITS ENGINE MODEL. AFTER MY OWN EXTENSIVE RESEARCH BEFORE SHOPPING FOR MY 2ND PREOWNED TOYOTA I NEVER DID COME ACROSS ANY SUCH INFORMATION REGARDING PROBLEMS/RECALLS & WOULD HAVE NEVER MADE THIS PURCHASE. I HAVE ALWAYS BEEN A TOYOTA FAN & AM VERY DISPLEASED WITH THE ENGINE SLUDGE PROBLEMS I LATER DISCOVERED AND ALSO THE FACT THAT THE DEALERSHIP WHICH SOLD ME THIS PREOWNED TOYOTA COVERED UP & PROVIDED ME WITH A FALSE CARFAX REPORT. I HAVE MY PROOF OF ROUTINE OIL CHANGES + THE CARFAX REPORT SHOWING ALL PREVIOUS OWNERS(2) ALSO MADE ROUTINE OIL CHANGES. I FEEL I AM A VICTIM OF A MANUFACTURES DEFAULT IN THIS ENGINE MODEL. I HAVE OWNED MY PREOWNED TOYOTA FOR ONLY 5 MONTHS AND FOR THE LAST 2 MONTHS I HAVE HAD IT SITTING IN MY DRIVEWAY DUE TO ONGOING ENGINE TROUBLES I AM UNABLE TO TEND TO FINANCIALLY & DO NOT WISH TO DO ANY FURTHER DAMAGE TO IT. I AM GREATLY DISAPPOINTED. [XXX] 'INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
