2005 Acura TL Owner Comments

problem #6

May 052005

TL 3.2L V6

  • Automatic transmission
  • 20 miles


About 10 years ago, Battery drain and replaced battery 2 times. Then researched it and found via descriptions a heated area corresponding to the HFL module. YouTube video showed how to disconnect it. The garage door link as well as hands free phone never worked and the GD dealer insisted I didn't know how to program it. Found a TSB or Recall on the 04 module and Acura wouldn't do anything for me. Went all the way up the chain with the same response from them ie FU. I have set up several corporate networks as well as building my own PC's so I know what I'm doing. Their CS sucks. They insist that we are wrong and their POS units just dont work and they want almost $200 just for the module that they even admitted and have proven was faulty.

Starter went out at about 170,000 in 2018. Dealer wanted $1200. YouTube video and $65 for new one from Amazon and 1 hour to replace. Dealer closed down within a few months. Ripoff.

More inoperable features on a luxury line that does not hold up to the test of time.

My car went through 2 batteries in a three month period, and I found out that the problem was the HFL module that would activate when the car was off, I didn't want to pay 500 dollars so I unhooked it and the problem has been fixed

Battery drain resulting from hands free link. First time this has occurred. Anyone know how much repair might cost. I have not activated the hands free link and have had the car since 2014. Also had to replace the transmission at 105,800 miles

After numerous complaints to Acura, we were finally instructed to bring our 2005 TL to an dealership. The service claims the blue tooth was draining the battery. A parasite. We replaced the battery then brought the vehicle to the dealership to disconnect the blue tooth. To our surprise, the dealership wanted $399.00 to disconnect the blue tooth. not knowing this fee, we went to the manager, they agreed to disconnect the blue tooth at no cost.

A couple years later we had to replace the battery again. A couple years later we returned the battery for a replacement battery. The new battery was covered under warranty. In January 2014, the car needed a new battery. Our Acura mechanic did an electrical test, a parasite but nothing overwhelming to kill another battery. They suggest we get an optima battery which should last the lifetime of the TL. We purchased an optima for $200. Last week, the car once again began to start hard. Each time we started the car it became more difficult.

We went to the store where we purchased the optima in 1/2014 to learn the battery went bad. Coincident! Don't think so. On Thesday 12-22-15 only 23 months after the purchase of the optima battery the Achra TL required another battery.

Let me inform Honda, I Don't abuse or misuse things we have been fortunate to afford. I come from the old school where we take pride in our belongings. We don't leave the lights, radio, seat heaters, A/C, etc on when departing. We understand this shortens the life cycle of the product along with the fact it would takes more cranking amps to start per the seasons. We are not made of money either.

Help with such problems would be appreciated.

New battery and it still goes completely dead whenever it feels like it.been to the shop they cant pin point the problem but something turns on And overnight draws all the life out of the battery. Sometimes it doesn't happen for months then it happens twice in two weeks. Shop cant pinpoint the draw. Have even left out a fuse trying to pinpoint the problem. Bought the car used a year ago. I Have to carry battery pack jumper with me cause you never know when it isn't going to start
