Notes: The 1999-2003 Acura TL has a known & widespread defect with the transmission.

Honda fixed some vehicles with a recall in 2004 by changing the oil cooler return line. To settle a class action lawsuit in 2006, Honda extended the transmission warranty on some of these Acura TL's to 93 months / 109,000 miles.

Now these vehicles are past the warranty limit, so buyer beware.
