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.
The inside rear view mirror may become discolored or difficult to see clearly from. A revised mirror is available to correct this concern.
The supplemental restraints system (SRS) warning light may illuminate with code B0111 and/or B0116. Our technicians tell us Lexus has several service bulletins regarding the SRS system. It is not uncommon to replace one or more airbags to correct these fault codes.
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.
The Check Engine Light may illuminate with codes P0171 and/or P0174 due to a lean running engine. Symptoms may include: Hesitation on acceleration, lack of power, and poor fuel mileage. This is commonly caused by a dirty mass airflow sensor. Our technicians tell us the sensor may be cleaned using an approved cleaner but replacement is often required to correct this issue.
The Check Engine Light may illuminate with code P0867 and/or P0990, related to the transmission fluid pressure sensor. Our technicians tell us a revised transmission fluid pressure sensor and upgraded software are available to correct this concern.
