I own a 2000 RX 300 first my parking brake light remains on even though the parking brake is not on, next the windows including the sun roof would roll down when I touched the driver's window button or when I turned the ignition key to off position. Now the engine light comes on and off and there is a different sound coming from the engine. Overwhelmed with all I took the vehicle to a Toyota dealership near me and was told that I have sludge and the engine needs to be replace. I not sure what to do.
Please give some advise.
