The contact owns a 2007 Acura TL. The contact stated that the battery power was drained after driving the vehicle for less than 48-hours. No warning light was illuminated. The vehicle was taken to an independent mechanic, who determined that the Bluetooth in the vehicle was draining the battery. Bluetooth was disabled, but the failure recurred. The contact had since replaced the battery twice within two months, each time with the same brand of battery. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 90,000.

The battery drains after the car sits in one spot for more than two days. Had to buy a new battery. It did it again. The alternator is good. But the battery keeps draining. Can't afford to miss work or taking time to go get the battery recharged every week. This has been going on for a couple of months now.

Owned this car since new 12 years ago. Battery always drains if not driven in 7 days or so. Constant problem through 4 batteries. Just got a new battery and alternator. Car is garaged. Didn't drive it for 10 days. Dead battery again. Blogs tell me this is extremely common with 2004-2008 acura tl sedan 6-cyl. Blogs say it is the hands free link of bluetooth that is a chronic drain whether or not the car is running. So I park it in airport parking, take a trip, come back at midnight, a woman in long-term airport parking, totally unsafe for me, waiting for help to jump the car. Totally unacceptable. Not safe. You need to do something! Next block says "when did this happen" and asks for a specific date. I will use today' s date, but it happens anytime I don't drive it for 7 days or so. The bloggers all have the same identical same problem. This is chronic.

My 2007 accura tl has a battery drain problem. I have a new interstate battery in it. I park it on our driveway and after 3-5 days of it being parked, not driven, the new battery is drained of power and will not start the vehicle. I have to charge the battery. It starts and will continue to start as long as I drive it to re-charge the battery. This occurs very consistently and has for the past year, on and off.

Vehicle's battery drained while sitting for 2 weeks without driving it. Towed to dealer. Dealer diagnosed a battery drain coming from the handsfree link unit. Part was $350+. Dealer explained that the labor was $150+ whether they deactivated the faulty unit or whether they replaced it with a new unit. I opted for the new unit. Total bill was ~$800 which included ludicrous "dealer-compliant" towing company. Dealer also replaced battery at this time (under warranty because I'd had a similar problem 4 months earlier - however it was not diagnosed at that time as hfl unit). Car sat again for 1 week. Brand new battery is now completely dead again.

Parasitic battery drain. Battery (5 mo old)--no bluetooth. Battery tested by shop-ok. Acura link site said since 2005, acura hfl (hands free link) module defective, causing a short in system, thus draining the battery. There is also a service bulletin for this issue. To me, this is not only a safety hazard (dead battery) but a recall item (it has been ongoing problem that hasn't been fixed). The module is located in the roof, which sees extreme temperatures. The dealer knows about this problem and charges $700-$900 to replace the module. The module goes from $285 to $200 on-line and the design has not changed (johnson controls). The time it takes to r&r the module (unplug and plug in) is 10min. I ordered the part and installed myself. Please review this as a recall for all the acura owners who paid absorbent costs to have it replaced by the dealer and those of us inconvenienced with out of pocket $, dead battery and no bluetooth. I paid a bundle for the car originally because it was going to be the last car I was ever going to buy. Now I am selling the car to prevent the next costly repair.

The battery drains down if the car is not started for two days. I have to jump start the car everytime. I have replaced the battery but still the problem exists.

2007 acura tl battery sometimes drains completely if the vehicle is not used for 2 or more days (nothing left on). Some electronics must not be shutting down and continue draining the battery. Dealer claims it's normal that if you go on a trip your car might not start if it hasn't been used in a few days which is preposterous. Afraid to leave car at airport when traveling. I've had to bring the vehicle in twice in the last 12 months. First time they replaced the battery; last time they could find nothing drawing power. Web search reveals lots of people having this problem. Dealer admitted they're replacing lots of batteries - but that doesn't fix the problem.
