Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

NHTSA — Engine And Engine Cooling: Engine Problems Seal Of Avoid Like The Plague 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.

2001 Acura TL Owner Comments

problem #4

May 012003

TL 6-cyl

  • Automatic transmission
  • 25,000 miles


Various problems with the 2001 Acura TL. Bought used and has been in shop 6 or 7 times in less than one year. Brakes, transmission replacement, master cylinder. Brakes continue to seemingly have a have to almost go to the floor to stop, but dealership says this is normal on this type of vehicle. True or not-I don't know. Also, the check engine light keeps coming on, also the ABS and tc lights keep coming on. Also, it does not make sense that my car now has 50,000 miles on it when I hardly go anywhere. It seems the odometer is very inaccurate. There is no way I have put 30,000 miles on this car since April of 2003. Could not find any other information concerning the odometer issue, but was told by a mechanic that it's possible their could be a speed sensor issue in the transmission, which would also cause the check engine light to come on.
