Known Problems

The Check Engine Light may illuminate because the mass air flow sensor sends incorrect information to the engine control computer. This can cause a loss of power on acceleration. A failed mass air flow sensor will require replacement.

A clicking type noise may be noted from the rear of the vehicle while driving. Our technicians tell us that revised rear coil springs are available which may correct this concern.

Higher mileage cars can develop creaking and groaning noises in the front suspension, particularly when coming to a quick stop. Inspection and replacement of any worn parts should correct this concern.

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 Check Engine Light may illuminate on vehicles with an automatic transmission, with codes P0751, P2714, or P0894 stored. Our technicians tell us these may be "false" codes. Revised powertrain control module (PCM) is available to correct this concern.

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.

A shift "lag" may be noted when accelerating from speeds of 10 to 20 mph. A software update for the transmission control module has been released which may correct this concern. Software updates are commonly most effective on newer vehicles. Higher mileage vehicles may exhibit a similar symptom caused by a component failure. However, whenever major transmission repairs are performed the transmission software should be checked and updated as necessary.

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.
