1999 Lexus LS400 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

THE DEALER WAS NOTIFIED AND HE WAS INFORMED THE THROTTLE BODY WOULD PROBABLY NEED TO BE REPLACED. ALSO, HE WAS INFORMED THAT DUE TO THE TYPE OF FAILURE HE WOULD HAVE TO CONTACT THE MANUFACTURER. THE MANUFACTURER WAS NOTIFIED AND INFORMED THE CONTACT THAT THE LEGAL DEPARTMENT WOULD HAVE TO BE NOTIFIED BUT OFFERED NO OTHER ASSISTANCE.

NHTSA ID 10487438 · filed Dec 5, 2012

I AM REPORTING THIS BECAUSE IT MIGHT PROVIDE A CLUE TO THE TOYOTA RACING ENGINE PROBLEM. ON EACH OF TWO DAYS BEFORE I TOOK MY 1999 LEXUS 400 TO THE DEALER FOR REPAIRS, THE ENGINE WOULD RACE AT AN ESTIMATED 4,000+ RPMS AND EMITTED A GRINDING SOUND AS THE CAR WAS STARTED. AFTER TURNING OFF THE ENGINE WITH THE KEY, THE CAR WOULD RESTART WITHOUT A PROBLEM. STRANGELY, THE DEALER DID NOT RECORD THIS PARTICULAR COMPLAINT, BUT STATED THAT DIAGNOSIS REVEALED THAT STARTER WAS FAILING. I WAS CHARGED $990 FOR REPLACEMENT AND REPAIRS. I COULD NOT GET A SATISFACTORY ANSWER AS TO WHY A FAULTY STARTER WOULD CAUSE THE ENGINE TO RACE. I HAVE DRIVEN THE CAR OVER 10,000 MILES SINCE THEN WITHOUT A PROBLEM. *TR
