The hfi unit/bluetooth overheats or draws power when car is not on. After 2+ days of not being turned on. It drains the car battery.

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 won't start after not being used for two days or more. It's been noticed since 2015. Battery was replaced 3 times in ten months. It's a safety hazard that Acura should be addressed/recalled. Went to my car mechanic to have it diagnosed and was told it's the vehicle's hands free module (bluetooth) that's been causing the drain. I checked online and found out it's been a major issue on this vehicle. Honda/Acura needs to recall this unit before it causes major accident. It is a safety issue that should be fixed immediately.

I bought the car yesterday and while I sitting in the car lot, after purchase, I was setting up the radio and hfl link. This took maybe 10 min or less. During this time a relatively new battery was completely drained. The hfl never even hinted at working to connect to blue tooth. I also have a 2005 Acura TL this kept happening to. The dealer recently told me it's a known problem, but not a recall so inqoukd have to pay to have it fixed. Since it was really expensive to fix he suggested I just remove the hfl link. Which I did from the 2005 TL I have. I haven't had a problem with the battery since. Now this same thing is happening to the 2007. I'm just wondering how long it will be before I have to replace this brand new battery from the hfl link draining it. I can't let the car sit for more than 3 days or it will be completely dead. I would like to have both my 2005 and 2007 hfl working. This seems to be an Acura problem and not just for a few cars.

My passenger side dash cracked around the airbag. This allows for moisture to get into the airbag compartment which degrades the passenger airbag. Acura refuses to replace. The vehicle was stationary and happened overnight.

Handsfreelink module draining my battery after car has been idol. Module was replaced originally in 2009, and that replacement now completely drains battery within 72 hours leaving car immobile.

My car sat at airport for approximately a week and would not start upon return. Got a jump and was ok for about a week when again it would not start after sitting in the garage for 3 days. I took the battery to the store for a replacement. He tested this 2 year old battery and it was perfect. I went on-line to search for this problem and the years 2004 through 2007 have a large number of incidences exactly like mine. The problem that the on-line audience has found is that over time a partial short circuit in the hfl (hands free link) module appears. This is clearly a latent defect in this module. I wrote to Acura customer service and their response did not address the specific problem. I got a "cook- book" response that I should bring it to the dealer for them to check it out. Is there anything you can do regarding such latent defects for out-of-warranty vehicles?

There is a drain on the battery. We replaced the battery. If the car sits for just an hour or sometimes a few days, it may not start because the battery has drained. We have had to jump it and trickle charge it multiple times. From searching the internet, this is not a new problem for Acura owners. Acura should fix this as so many cars are having the same issue.

The contact owns a 2007 Acura TL. The contact stated that the vehicle failed to start. The roadside service changed the battery on numerous occasions. However, the failure recurred. In addition, the contact mentioned that while driving approximately 65 mph, the battery warning light illuminate and the vehicle vibrated uncontrollably. The contact had to drive the vehicle in a lower speed and it suddenly stalled. The contact was not able to get the vehicle restarted. The dealer was not able to diagnose the failure. Manufacturer was notified of the failure. The approximate failure mileage was 35,000.

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.

After being parked for about 2 weeks the battery started fine. I drove 10 miles, turned off the car for 1 hour, tried to start the car again and the engine would not turn over. The inside lights were on but the headlights were dim. After trying to start the car several times both the inside lights and the headlights were completely out. I had to call aaa for a jump because the battery was dead. I thought this was odd but then I remembered a friend of mines has a 2008 TL and he has to jump his battery weekly. So I did an internet search and learned that thousands of Acura owners are having the same problem and most attribute the problem to the hands free link systems (hfl). So I called Acura and they confirmed that the cause is most likely due to hands free link system. Why hasn't this been a recall" is Acura waiting for some to die first" this is safety issue and a racket! the dealer charges nearly $200 to diagnose the problem and several hundred more dollars to fix it. A recall is warranted!!!

Last month we had to take the car to dealer bc it wouldn't start. Battery was drained due to hands free system not turning off even when car was off, so we opted to disconnect system (free) instead of paying 6-800 dollars to repair. Also car is kept in garage during day and last week we noticed large crack running vertically along outer edge of airbag compartment. No reason for this when car is kept clean and out of direct sun. Checked online and found numerous reports of this happening for no reason. I am worried that airbag may not function correctly or may engage without warning if dash is broken. This is not covered and no recall yet. Very disappointed with this bc I love my car.

Key fob folded while driving due to wear, as a result weight of rest of key chain caused ignition switch to rotate to 'off' position resulting in loss of power while driving.

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.

The contact owns a 2007 Acura TL. The contact stated that while driving 65 mph, the vehicle stalled and all of the warning lamps illuminated. The vehicle was towed to the dealer. The technician diagnosed that the hands free link failed, causing the battery to drain. As a result, the alternator and hands free link needed to be replaced. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 15,000 and the current mileage was 119,000. Updated 98/29/13 updated 9/13/2013

Vehicle was parked in driveway; had not been driven for 2 hours. Heard a pounding, hammering noise from inside my house and when I entered the driveway the vehicle's engine was running, although it was a very rough idle. There was a smell of something burning coming from underneath the hood. I inserted the key into the ignition to turn off the engine but since the ignition was not in the on, or run, position, to begin with, the key had no effect on the engine (that is, I could neither turn the engine off nor on, using the key), and the vehicle continued to roughly run. I then called the fire department but the vehicle had stopped running when they arrived. However, the fan was running and they thought that was natural after the engine had shut off. I told them that this vehicle had never had the fan run after the ignition was turned off, that it did not have a remote starter (they asked), and that it had really started by itself. They said the smell was a result of an electrical fire in the engine and they disconnected the battery so that the problem did not recur. There were no visible flames and the vehicle has not yet been examined for damage as the incident occurred just a few hours ago. I am the original owner of the vehicle (6 years).

My battery failed for the second time in a couple of months and required a jump in order for the car to start. I took it to an Acura dealership where they determined that the handsfree link system was electrically faulty and was staying on continuously, whether the car was running or not. Hence, there was a constant draw on the battery. To (hopefully) resolve the problem, I had the dealership replace the battery and the handsfree link system.
