2005 Acura TL: battery drain or dead battery

Filed Jan 27, 2022 · MI

In both 2012 and 2014 I complained to Acura CS and was told that they wouldnt do anything for me when their hands free unit refered to in TSB 08-057 This was causing a parasitic power leak draining the battery overnight. After researching the cause online and the solution which was to remove the defective HFL unit which was done. Yesterday I came across that TSB and contacted Acura with my correspondence from 2012, 2014 and the TSB. So far I'm getting the run around. I just want a replacement module for the one that I have kept as a reminder of how I was screwed by Acura. The TSB states all 2005 TL's are affected yet today they had the gaul to say it was no longer in warranty. This is a critical safety item in that it provides hands free utilization of the cellular phone. This came defective from the factory in that I was never able to either connect to the garage door opener or to the phone and was extremely angered by the dealer insisting that I just didnt know what I was doing. I perform surgery in peoples mouths for a living and build and program computers and networks on the side. I know that this module with part number 1135133c1m3m04 or 3qc32dc2 on 2 stickers on back of the circuit board are defective. The TSB only lists what is on the plastic cover to the module and not the module itself. Please verify that these modules are in fact garbage.

My battery would be dead if I didn't drive my car every day. Then I found out there is a parasitic drain on the battery from a faulty hands-free bluetooth module. I watched a video then disconnected mine myself, problem solved. I've used a headlight restoration kit because the lights are yellow and they have spider-cracks all in them, it really affects the brightness of the light itself. The dashboard is cracked beyond repair and I'm terrified of getting into a wreck in my car, the dash would become shrapnel!

I purchased this vehicle from the oringinal owner 11-17. He didnt inform me of any problems with the vehicle. Three days after purchase I had a dead battery. Then I noticed the speedometer and tach would stop working when I was driving, also the vsa warning light would come on when I was driving. I searched on line and found that there was many complaints about my same problems, and that the dealer was no help at all. I tried disconnecting the hands free link, but I still had a dead battery the next day. The only solution I have found is to disconnect my battery every day when I come home. I replaced the battery in jan. 2018. There are also receipts in the vehicle from the origanal owner for the same problems.

Purchased new, since 2005 the vehicle has had a parasitic battery drain which causes the vehicle not to start. Over 10 batteries have been replaced by acura dealerships or aaa. I was told by former certified acura service representative that this problem is with the vehicles hands free system control module. Acura has known, internet research, and my conversation on this date 5/9/2016 with an acura customer representative confirmed that acura has known about this problem since 2004. This is a serious problem which can cause the vehicle to stop moving resulting in loss of power steering, control, or potential serious accident. Another serious factor is that there is no warning sign when the vehicle battery will fail. In the event that the battery fails with out any warning whatsoever in an extreme cold, heavy rainfall, flood conditions could possible result in loss of life. Think of the possibilities with children in the vehicle. Common sense dictates that my complaint and all others who have taken time to file complaints regarding this serious problem should result in a the federal safety agency recall. The people of the world who buy vehicles don't need bad takata inflators or bad ignition switches .what we need is a the federal safety agency which will responsibly enforce all automobile manufactures to provide quality vehicles that have the best safety features.

The hands free link (hfl) modules have been failing resulting in a 200ma current drain. This results in the module shorting out and may subsequently result in a fire. I discovered this as a result of the battery draining to 5 volts overnight as well as a much high than normal temperature of the plastic cover under the hfl module. I removed the module according to acura service bulletin 05-020 dated september 23, 2005.
