2002 Acura TL ProblemsCheck Engine and D4 Lights Flashing
The 1998-2014 Acura TL V6 may develop issues with the automatic transmission.
Rough shifting may occur, and the “D4” light and check engine may begin to blink. The check engine light will also illuminate, and OBD trouble codes P0700, P0730, P0740, P0780, P1768 and/or P1768 will be stored in the computer.
If the transmission shifts roughly, the failure is very likely mechanical failure of the transmission. If the transmission performs normally, a faulty sensor, or dirty transmission fluid may be the case.
In most cases, it is necessary to use professional diagnostic equipment to provide a diagnosis, and complete the repair.
The longevity of the transmission is dependent on strict adherence to the manufacturer's recommendation for ATF replacement intervals and procedure.
I found out that at only 83000 miles my TL had to have the engine mounts replaced already at a cost of almost $800.00
Automatic transmission problems are common and these transmissions have high failure rates. Acura has voluntarily extended the warranty on many of its automatic transmissions, so be sure to check with an Acura dealership to confirm warranty coverage.

2002 Acura TL QuestionsOBD2 port fuse? (1 answer)
I went to get my emissions done and the tech said there was no power to the port. He suggested a fuse might be out, perhaps the cigarette lighter. Is that the ACC relay fuse? If not, which fuse? I don't see cigarette lighter on the fuse diagram.
Is it the bushings?
2002 Acura TL RecallsDriver's Front Air Bag Defective
In a crash that deploys the driver's front air bag, the inflator of the air bag can rupture, causing metal debris to strike vehicle occupants. Dealers will replace the front driver's air bag inflator free of charge to correct the concern.
This limited regional recall is for vehicles currently registered or first sold in Florida, Puerto Rico, Hawaii and the U.S. Virgin Islands, and equipped with Takata-brand air bag inflators. Upon deployment the driver and/or passenger airbag inflator could rupture, increasing the risk of personal injury. Honda dealers will replace the affected airbag inflator modules to correct this concern.
Honda is recalling 2,430 vehicles because a driver's airbag inflator, installed as a replacement part, may be defective. In the event of deployment, these inflators could produce excess internal pressure and rupture, increasing the risk of injury to vehicle occupants. Dealers will inspect and replace the driver's airbag inflator as necessary. The recall is expected to begin by June 27, 2011.
