Incomplete Instructions On Radio Security Code 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.

2003 Acura TL Owner Comments

problem #1

Feb 012012

TL TL 3.2L

  • Automatic transmission
  • 62,000 miles


When power is disconnected, the radio asks for a security code. Unfortunately, the owner's manual only give instructions on how to enter the code, but left out a key step: First, disconnect the antenna located at the back window. I handled this issue three times now and can confirm this is a critical step. Otherwise you'll enter the code repeatedly and the radio will lock you out.

I called several dealerships and got the following responses.

1) We need to dismount the radio for one hour of labor at $110.

2) You need to disconnect the antenna

The second hint gave me the clue to disconnect it at the rear window. Why dismount the radio just to unplug it from the back??
