Known Problems

Drivers may hear a loud noise, much like a vacuum cleaner, coming from their engine on cold starts. This affects the 2003-2004 Lexus GX470. 

The noise is from the secondary air pump, which sends hot air to the catalytic converter when the engine is cold. This allows the catalytic converter to clean exhaust better, and lower emissions while the engine is warming up.

Pump failure may result in:

Fixing the issue involves removal of the intake manifold, and replacement of the secondary air pump.

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

The air conditioning light may flash or an AC error message may be displayed. Our technicians tell us this is commonly due to a fault with the AC amplifier, as revised part is available to correct this concern.

A clicking or knocking type sound may be noted from the brake actuator when applying the brakes lightly, or if the brake pedal is pressed while the vehicle is stopped. Our technicians tell us a revised brake actuator is available to correct this concern.

Drivers of the Lexus RX300 may notice excessive oil consumption between oil changes, even to the extent of the engine oil warning light displayed on the multi-function display.

This issue is known to be caused by infrequent oil changes causing engine sludge, or worn piston rings. 

The engine should be cleaned of oil sludge, and if oil consumption remains excessive, the engine may need new piston rings, or other internal components replaced. 

To avoid this issue, change the engine oil and filter every 3,000 miles, and ensure the proper grade of oil is used. 

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.

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.

A brief rattle or knocking noise may be noted on initial start up. Our technicians tell us if the noise is determined to be coming from the timing chain area, there are updated variable timing gears available to correct this issue.

An abnormal fan belt noise may be noted. Our technicians tell us a revised fan belt tensioner is available to correct this concern.

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.

On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.

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.

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