Reported: 2004-06-25 (June 25, 2004) · Model years: 2004
ON CERTAIN PASSENGER VEHICLES, THE IMPELLER INSIDE THE FUEL PUMP MAY HAVE BEEN IMPROPERLY MOLDED DUE TO A MANUFACTURING ERROR. ALCOHOL IN SOME FUELS MAY DEFORM THE IMPELLER AND CAUSE IT TO COME INTO CONTACT WITH THE PUMP HOUSING.
Consequence: THIS CONDITION COULD INCREASE THE ROTATIONAL RESISTANCE OF THE IMPELLER AND, IN THE WORST CASE, MAY RESULT IN FAILURE OF THE FUEL PUMP.
Remedy: DEALERS WILL REPLACE THE FUEL PUMP. OWNERS WILL BE NOTIFIED IN JULY, 2004. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT LEXUS AT 1-800-255-3987.
Reported: 2004-07-01 (July 1, 2004) · Model years: 2004
ON CERTAIN VEHICLES WHEN THE ACCELERATOR IS OPERATED QUICKLY, A SMALL PIECE OF METAL MAY SEPARATE FROM A RETAINING COLLAR LOCATED IN THE INNER PART OF THE AUTOMATIC TRANSMISSION. THIS SMALL PIECE OF METAL MAY BECOME CAUGHT IN THE PARKING LOCK MECHANISM.
Consequence: THIS MAY CAUSE THE PARKING LOCK SYSTEM TO BE INOPERATIVE WHEN THE TRANSMISSION SHIFT LEVER IS PLACED IN THE PARK POSITION, THEREBY INCREASING THE RISK OF VEHICLE ROLL-AWAY, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL REPLACE THE TRANSMISSION. OWNER NOTIFICATION IS EXPECTED TO BEGIN DURING JULY 2004. OWNERS SHOULD CONTACT LEXUS AT 1-800-255-3987.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
