Among the 6 model years of Acura TL in our records for electrical problems, this one ranks #3 by owner-complaint volume.
No new NHTSA electrical complaint has been filed on this vehicle in over 7 years — the issue may be aging out of the active population.
If the fuel pump loses power while driving the engine could stall without warning which could result in a crash.
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The 2005 TL's dominant issue is parasitic battery drain stemming from the hands-free Bluetooth module. Owners consistently report the battery dying after just a few days of non-use, forcing them to replace batteries 4 to 10+ times over the vehicle's life. Multiple owners discovered the problem online and found that simply disconnecting the module—per Acura Service Bulletin 05-020 from 2005—permanently solves it. Owners note that Acura knew about this defect since 2004 and have filed a class action lawsuit, yet no recall has been issued.
Dashboard cracking is the second widespread complaint. Owners report large cracks appearing over the odometer and directly above airbag deployment zones, sometimes on garaged vehicles with minimal sun exposure. Owners fear that if airbags deploy, the shattered plastic will become shrapnel and cause additional injury.
Less common but noteworthy: one owner experienced engine stalling and fuse-box failure that caused smoke in the instrument panel; another reported unintended engine surge tied to cell-phone placement near electronics. Headlights yellow and develop spider cracks, reducing output. One door lock failed to respond to the button. No manufacturer remedy is documented for the dashboard or headlight issues.

The car is been sitting for about 4 days and the battery is dead again. This has been the issue since I bought the car. It was taken to the dealer when this first happened and I was assured that the problem has been fixed. However, over the years I have replaced numerous batteries.
