2012 Acura TL Problems

Automatic Transmission Issues

The automatic transmission tends to malfunction more often than in similar models. The Check Engine Light may or may not illuminate.

Check Engine Light for Running Rough and Difficulty Starting

The exhaust recirculation valve (EGR) on the 1995-2014 Acura TL may fail, causing:

  • Illumination of the check engine light
  • OBD trouble codes P0401 and P1491
  • Rough idle
  • Reduced fuel economy
  • Engine vibrations
  • Hesitation or stalling
  • Long cranking before engine starts
  • Failure of state or federal smog tests
  • The EGR valve has open and closed positions, and opens or closes on command from the computer.

    Exhaust gases constantly pass through the valve when it is open, leaving carbon deposits on the valve. These carbon deposits may lead the the valve sticking in the open or closed position.

    To correct this issue, sometimes it is sufficient to clean the valve, but replacement is recommended in all cases.

    Check Engine Light and Engine Takes too Long to Start

    The 1998-2014 Acura TL commonly has problems with the EVAP canister vent solenoid. It stops responding to commands to open and close, and the following occurs:

  • Illumination of the check engine light
  • OBD trouble code P1457 is stored
  • Engine takes longer than usual to start
  • Fuel mileage decreases noticeably
  • The valve is located on the charcoal canister, and is meant to open and close upon command. It fails due to corrosion breaking one of two internal seals, which allows air to escape the system, signaling the OBD trouble code P1457.

    Correcting the problem can be done by replacing the vent valve, or, in some cases, cleaning and resealing the vent valve has been successful. You can get an estimate for this repair here.

    A worn, missing, or loose gas cap can cause the same issues.

    Charging system indicator lights whenever I start the car (1 answer)

    On my 2012 Acura TL the charging system indicator stays lit whenever I start the car but I have no problem driving or using other features in the car and service person can't find any problem with the battery.

    The rear brake cables run under a support bar and are exposed.Is this normal (1 answer)

    There are two cables attached to the brakes and I don't know if they are brake lines or emergency cables. In any event they are attached to and run under a metal bar and are exposed and could catch on something and be torn off. Should they be OVER the bar and protected from being damaged.

    Driver's Frontal Air Bag Inflator Ruptures And Sprays Metal Fragments

    The driver's frontal air bag inflator may be susceptible to moisture intrusion, which over time could cause the inflator to rupture. If this happens, it would spray metal fragments upon deployment. Dealers will replace the driver's frontal air bag inflator free of charge to resolve the concern.

    I have Acura TL, 2012 FWD. I do not know if anybody else have the same problem as me, but would like to find out. I think Acura has a serious problem with leather. Yes, leather on the seats.It is bulging up in no time. It is depressing to see-mostly on the driver seat since it is used most, and I am not overweight.
    Have the 12 acura TL tech. and love it. This car will do everything, and when you think your done knowing it all, something else happens that you didn't know it could do. HAHA! Love this car, and it hauls the mail too!!! Great car for people in snow country with the front or all wheel drive. The white pearl color is great and not an extra charge like all the other car companies charge. Come on,...
