Known Problems

Various radio issues may develop, including: volume control, radio shuts off by itself, or the radio screen is scrambled or blank. Our technicians tell us an improved radio is available to address these concerns.

The inside rear view mirror may become discolored or difficult to see clearly from. A revised mirror is available to correct this concern.

The Check Engine Light may illuminate due to an EVAP system fault. These faults are commonly EVAP canister or gas cap related. Our technicians recommend diagnosing the stored fault codes before replacing any components.

Various concerns with the navigation & heater control display, along with Bluetooth compatibility may be corrected by upgrading the appropriate software.

Debris can get into the idle air control valve. This will restrict the air flow into the engine, causing idle speed and/or stalling when cold. The valve can be cleaned or replaced to correct this concern.

Owners have reported experiencing rough deceleration, inability to engage overdrive, and a check engine light with diagnostic trouble code P0770. Problems with the torque converter or deferred transmission maintenance can trigger this. Professional transmission diagnosis is recommended to address this issue to prevent unnecessary part replacement and expenditure.

The Check Engine Light may illuminate with various EVAP system fault codes stored. Our technicians tell us this may be caused by a sticking EVAP Purge Vacuum Switching valve. An improved valve is now available to remedy this problem.

A squeak type noise may be noted from one or both front seats. Squeaks can be caused by contact between the seat track locating pins and the vehicle floor pan. Our technicians tell us the repair involves removing some of the seat locating pins.

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.

Several changes have been made to improve this; a computer software upgrade, revised valve lash adjusters, and a redesigned timing chain are all available to try and correct this concern.
