general problems of the 1998 Lexus ES300

The day before the accident happened all the tail light were off and I found the fuse for tail light was blew. So I replaced the fuse. Next day,when I turned on headlight while driving on highway 680, the "r" indicator on the dashboard became on as well -- now both "d" and "r" were on. It puzzled me for awhile so I decided to turn off the headlight. As soon as the headlight was turned off , the car "hesitated" on freeway. I took the car to dealer for service who claimed they have never seen this before. After 3 days of services, they said some wires were crossed and charged $581 for replacing those faulty wires and one controller. The car is only 13 year old and about 100 k miles. I would definitely classify this accident as a defect by manufacture. I want to file this compliant to see any other Es300 owners have experienced such problem.
