The water leak has been discovered. The sponge gaskets on the tail light assy were deteriorated. Took the car back to the dealer(Acura dealership). Did not want to fix but sat on my salesman's desk convincing him it was there before I purchased and would not have purchased it if I knew about the leak. Off the car went for 4 days. They even gave me a loaner-Acura MDX. What a truck! Well it is back and have had rain, sleet and snow and no water. They also filled the holes with puty where the light goes into the body. I need to say that my 2000 RX300 is a great car. Reading about the transmission problems and still see this as a great car. When I took the car out for a test drive it had an alignment problem. Dealer fixed and I asked to get the trans fluid changed without evening knowing about the tell tale problems. Just makes sense to get it drained. It was used with 46700 miles on it. I strongly agree with others in the forum to change the oil and do what is needed and the vehicle will last. Definitely love this forum. Have learned a great deal. Thanks to all!
