fix your own Running Light Relay module
Day time running lights are required in Canada. The DRL on the Acura 2.5TL is controlled by a relay module. It appears that the relays heat up during operation and the heat eventually melts the solder joints that connect the relays to the circuit board. It is a simple fix to resolder the joints.
You will need a soldering iron and fresh solder to complete the fix. A desoldering tool or desoldering wick will make the job easier.
Procedures:
1. Remove the glove box.
2. The running light relay is a gray box about the size of a deck of card but twice as thick. It is mounted by a metal tab on the right wall of the glove box cavity.
3. Disconnect the wire harness from the relay module. You have to push the locking tab in while pulling the connector down.
4. Use a 10mm wrench to remove the bolt holding the module to the side wall.
5. Take the module and ply the bottom cover off. The circuit board can slide out.
6. There are two big black cubes on the circuit board. These are the relays. Flip the circuit board over to the solder side, and locate the large solder tabs that join the relays to the circuit board. If you look at the solder blobs closely, you may see cracks in them.
7. Use a soldering iron and remove as much as the old solder as you can. A desoldering tool will be handy.
8. After you clean up the old solder, apply new solder and check that all the solder blobs are nice and shiny.
9. Replace the running light module and it should work.

I don't know about the made in Japan models. On the other hand, I would be very surprised if the DRL system is different between the NA made and Japanese made models.
I would just give it a try. The procedures is pretty simple.
