One problem related to engine exhaust system has been reported for the 2000 Lexus RX300. The most recently reported issues are listed below.
While driving, the car jerks and then cuts off. This has happened at least half a dozen times within the last 2 months. Engine light is constantly on, even after servicing the car at local Lexus dealer. When car is parked, I noticed exhaust fume smells heavily with gas.
