“The contact owns a 2003 Lexus GS300. When the vehicle was started, the engine made an unusual revving noise. In addition, three unknown warning indicators illuminated and did not turn off. Also, when applying pressure to the brake pedal, the pedal stiffened, which made it difficult to make a complete stop. The vehicle was not diagnosed or repaired. The dealer and manufacturer were not notified of the failures. The failure mileage was 214,000.”
