Known Problems

Sludge can build up in the engine because Lexus did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary. Owners who changed their oil every 3,000 miles did not experience these problems. This sludge build up can lead to excessive oil consumption.

There are reports of intermittent failures with the heating and air conditioning control. The digital display might fail or the control might fail to switch between heater functions.

A seat position sensor fault code, B1153 may be set. Our technicians tell us a revised wire harness is available which should correct this concern.

Occasionally, the Check Engine Light is illuminated due to failures in the evaporative emission (EVAP) system. Our technicians tell us that proper diagnoses is generally required to confirm the exact fault causing the warning light to come on.

A creaking type noise may develop from the front suspension when driving over uneven road surfaces. Our technicians recommend inspection of the front sway bar bushings for deterioration and related hardware for correct tightness.

Our technicians tell us that some navigation system problems may be corrected by installing an updated navigation map disc.

Various user interface issues regarding GPS, radio system, and heater controls, along with bluetooth operation have been addressed with a software upgrade. Our technicians recommend that if you have issues with these systems, checking for the latest software should be the first step in diagnoses.

An intermittent no start condition may be caused by a failed "Push Start" switch. Replacing the failed switch should correct this concern.

Poor quality low speed transmission shifting may be noted. Our technicians tell us updated transmission software is available which may correct this concern.

Vehicles equipped with the Lexus Dual Mode Mobile phone system may experience poor quality sound, particularly from land-line calls. A redesigned telephone computer and microphone are available to correct this problem.

The multi-cluster display screen may remain blank and navigation system errors may be noted. Our technicians tell us that these issues can often be corrected by reloading current software upgrades.

When changing the air filter, it is easy to knock off a hose on the air filter housing, which is part of the emission control system. If the vehicle is driven with this hose disconnected, the Check Engine Light will illuminate.
