I first purchased my TL-S back in 2002 (2003 model year). The transmission failed in 2003, and again in 2009. Both were replaced under extended warranty. The transmission that was installed in 2009 has been working fine since, with a redesign to prevent future problems. The Acura service department was excellent in remedying the transmission problem, both times. It has been 7 years and 80k miles on my current transmission. My car currently has 190k miles. My TL-S still has strong acceleration and surprisingly compliant yet firm ride quality and capable handling after all these years. The interior materials are holding up well, and the dashboard still retained its original color. The leather seats have aged much better than my 2008 Lexus ES. If not for the transmission issues early on, I would've given this car a perfect rating. My TL-S has held up much better than my friends' BMW 323 and Mercedes C class, which they purchased around 2002, and both of which fell apart a few years ago. Asides from the transmission and a couple of broken window motors, I've only done routine maintenance on my car. Kudos to Acura for building a mostly bulletproof car.
Car is overall in great condition, but transmission is shaky and fuel economy is below average. I've taken car in for service and had taken all preventive measures in boosting fuel economy but only time will tell.
I purchased the 03 Acura TL S in 08. I paid $7,500. Worth every cent. I have had a Nissan Maxima / Mitsubishi Galant / Honda Accord/ Chevy Blazer/ Toyota Celica/ Ford Explorer just to name a few. This is by far the best car I have ever had. It had 70,000 miles when I purchased it. It now has 180,000 miles on it and still going strong. I keep up with the oil changes and tune ups. Just regular mantaince and it is as smooth as glass to drive. The acceleration smooth speed awesome just a fun & comfortable car to drive. My son is now driving it and loves it over the new 2014 Nissan Rogue.
I purchased this car in 2005 with 50000. It now has over 130,000 and is running strong. I have never had any problems, just routine maint. It has begun "rattling" but it is 12 years old! Handles perfectly, hugs the road, extremely reliable in snow. Couldn't be happier.
Bought this TL with about 60,000 miles on it and was very impressed.....for about a year then it started falling apart. A/C needed to be completely replaced. Transmission never shifts down in town, so it hardly ever runs below 2500 RPMs even at low speeds. The exterior trim is faded, the heat controls inside have a mind of their own...you can turn the system off and still have hot air blasting out. The wiring on the steering wheel stereo controls is fried and never worked right. I thought Acura made a quality product but I was very wrong. Disappointed with this car...it's kind of a piece of junk.
