I bought this car Sept 2010 with 110K miles. I drive at least 2,000 miles per month, this car has 141K now. 14 months and I've driven it 31K miles with NO PROBLEMS OR ISSUES. Oil changes and tires only. I drive my cars hard and I expect something to go wrong but the transmission shifts perfect and everything works perfectly. I go on 2-3 hour road trips at least twice a month with no worries. I trade cars about every 2 years and I have to say this is the best one I've had in a long time.
As with most of the 2003 readings, my TL lost its transmission at about 90K. As the warranty was shot after 10 years I had to pay 3K+ for a new transmission, DON'T GO TO THE DEALER or you will pay 5K+ with a lesser warranty. The airbag sensor light went on and the dealer asked $650 to fix it, I figure I went most of my life without ever even wearing a seat belt until it was made a law, I can live with out airbags for awhile. So after 100K that about sums it up the major repairs. The comfort of the drive is the best I ever had, the engine is great; it can throw you back in your seat. Gas mileage is surprisingly good. The leather interior is average at best.
I bought the car in a dealer's auction with 149 k. I learn about the transmissionrecall and was scare when the car would occasionally shake during gear shifting. Took it the dealer and they stated I needed another transmission asap. Went to my local mechanic and he state transmission is good just had a broken motor mount and fluid need to be flush. Car drove good ever since, I love the speed. I pass newer car with ease. I hit 90 on the road easily going to Atlanta. I would definitely buy one again. My car is till operating but I gave it to my girlfriend since she dented the doors and bumper in an accident.
This is my wife's car. We purchased it in July 2003 new. I has given us service far superior to any car we have ever owned. (married 56 years). We returned it to the dealer for a recall on the transmission in 2005. Had the transmission serviced in 2009. The car now has 85,000 miles and still performs like new. On trips we average about 32 MPG. Seldom drive more than 65 MPH. Only problem is premium fuel.
