Lexus GS300 Problems

Excess Engine Oil Consumption

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.

Creaking Type Noise From Front Suspension

All wheel drive models may develop a creaking type noise from the front suspension when driving over uneven road surfaces. Our technicians tell us revised front sway bar bushings are available which may correct this concern.

Violent Downshifting

When braking in automatic mode, the car has a strong jolt @ 15 and 5 MPH. Lexus is stating new transmission and new transmission computer, also new rear O2 sensors. for a grand total of $7200.

Potential Fuel Leak

Due to the remnants of anti-corrosion plating, a fuel leak may develop from where the fuel pressure sensor is attached to the fuel delivery pipe. Any fuel leak always increases the risk of a fire. Dealers will clean and reseal the area of the fuel pressure sensor to correct this concern.

 

Accelerator Pedal May Become Stuck in Open Throttle Position

The plastic pad embedded in the floor carpet may interfere with the operation of the accelerator pedal. As a result, it may become stuck in a partially open position. A stuck accelerator can result in unintended vehicle speed, increasing the risk of a crash. Dealers will modify the plastic pad in the floor carpet. No owner notification schedule has be set at this time.

A Fuel Leak Can Develop at the Fuel Pressure Sensor Connection

The fuel pressure sensor monitors fuel pressure for optimum engine performance and emission controls. Lexus has found that some of these sensors can loosen from the fuel line, which may cause the sealing gasket to leak fuel. To prevent this from occurring in the future, your Lexus dealer will ensure that these sensors are properly fastened. No schedule of owner notification is available at this time.
