BACKGROUND

Acura has decided that a defect relating to motor vehicle safety exists in certain 2015 model year TLX vehicles. During
installation of the park rod and the EPR (electric park release) shaft, there are two issues that may have occurred:

1. The lock tab of the park rod may have been broken during assembly and the rod can pop out of the park disc; if the
rod pops out, the park lock will not engage.

2. When the EPR shaft was installed, the roll pin may have created some metal chips or debris that could have fallen
into the park pawl bushing. These chips may jam the park pawl and prevent it from engaging.

If either of these conditions occurs, the transmission may not shift into Park when the driver selects the Park position on
the electronic gear selector. Although the gear position indicator will display P, the park lock may not engage allowing the
vehicle to roll away and increasing the risk of a crash.

CLIENT NOTIFICATION
Owners of affected vehicles will be sent a notification of this campaign.
Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.

Some vehicles affected by this campaign may be in your new or used vehicle inventory. These vehicles must be repaired
before they are sold.

Should your dealership sell an unrepaired vehicle or fails to do the inspection or flush according to this bulletin that
subsequently causes injury or damage because of the recalled item, the dealership will be solely responsible to the
damaged party, and will be required to defend and indemnify American Honda for any resulting claims. To see if a vehicle
in inventory is affected by this recall, do a iN VIN status inquiry before selling it.

2. Place the vehicle in car-wash mode.

* Start the engine.

* Press the brake pedal, then press the Neutral button on the electronic gear selector.
NOTE: The vehicle will not enter carwash mode without the engine running.

* Press the ENGINE START/STOP button within 5 seconds. The power mode goes to accessory and the engine
shuts off.

* When the message Shift to Park appears in the MID and the letter N appears in the instrument panel, the vehicle
is in car-wash mode.
NOTE: The vehicle remains in carwash mode for about 15 minutes, then it shifts into Park.

3. Make sure the transmission is in Neutral by rolling the vehicle about 1 foot.
NOTE: If the vehicle is not in Neutral, the inspection procedure will give you an incorrect result. As a result,
you may think the vehicle only needs a transmission flush when it actually may need to have the transmission
replaced.

4. Remove the ATF fill plug.
