The hands free link unit has an issue where it stops working and drains the battery of the car. I've gone through 3 batteries in the last 6 months and when I finally disconnected the hfl unit, the car has been working properly.

Having issues with the drainage of battery. Three in one year. The culprit was the hands free link and xm radio. The bluetooth features in this car has caused it to shutdown completely several times or not start up. After searching online, this has been the complaint by thousands of other Acura MDX 2007. This is dangerous and may cause car accidents. This is too common an issue to not recall these parts.

This is the third time the electrical system has failed caused by "battery drainage". local repair shops do not know how to fix problems, but dealer's and Honda mechanics are very familiar with this horrible problem. Everyone fixing the problem knows very well this should be "a recall" matter, and creates a great road hazard as well are garage fires and loss of life. The things involved are "blue tooth" modular, air conditioner clutch relay, fuses. Regarding the blue tooth, this modular gets very very hot, and could cause a fire!! when the battery fails to charge while driving to get safely off the highway is very dangerous, much worst at darkness!! Honda needs to get their act together and recall and fix these problems now. My experience happened with the car in motion, and all indicators flashing, rear axle noises, heat inside car, loss of power, and vehicle in "kind of, a limping mode". very scary and dangerous occurrence. We are the original owner of the car, now with 140,000 miles, and always serviced every 3-5,000 miles. We have taken pride in this vehicle, until this "battery drainage" problem, now is effecting our thoughts about Honda Motors.

My 2007 Acura MDX dies almost everyday battery drainage. Replace the hfl module as well as the ac relay. Yet battery still drains almost everyday and have to jump start it just to leave for work.

Battery keeps draining due to hfl module. Replaced battery and still keeps on draining. Hfl unit hot enough to melt plastic and possible fire hazard. This issue has been reported by hundreds if not thousands of MDX drivers and Acura says they never heard about it. Yea right! for the price of the vehicle that we all pay for we expect great results. Acura you need to recall and replace the hfl modules before this causes a car fire and possible house fire.

I purchased a 07 Acura MDX 1 month ago with 115,500 miles and got the extended power train warranty. Hall Nissan pulled the vehicle off hall Acura's lot. They printed out a receipt from all the work Acura did before I bought the car, and ensured me nothing was wrong with it that it went through a 150 point inspection. I took it to Acura 2.5 weeks after I bought it because the check engine light came on and a tranny code popped up. They diagnosed the car and found $7,000 worth of malfunctioning equipment. Transmission range sensor, both front struts, ac coil and magnetic clutch, front cv axle boot leaking, rear shocks, rear sway bar bushings, transmission cooler hose leaking. I have spoken with numerous managers about this, they wont replace the cv axel assembly (suggested fix), the transmission cooler line (suggested fix), or front struts or back shocks which failed upon inspection. They are telling my warranty wont cover it because I haven't owned the vehicle for 60 days. They need to fix this. They should not have sold me a car telling me everything is ok and when I take it back to the same Acura service shop that did the original inspection 2 weeks later there is now $7,000 worth of damage. There is a few things wrong with it that was said was fixed on the original work order that they never did. When I go over bumps the suspension makes a clunk from the front. After researching online many people have the same issue.

Several times, the electrical system shuts off while driving. I was lucky to be in the neighborhood and not on a highway. The dealer stated there is a problem with the bluetooth and we have had it replaced. This is the second time this has occured. The first time it happened, the bluetooth was under Acura warranty. It was explained to me that the bluetooth is drawing energy constantly and the dealer suggested we disconnect it to avoid the same issue happening again. But that is the reason I had bought the car in 2007. It had integrated bluetooth. The times the car off while driving luckily was at a traffic light and in our neighborhood. I just hope it does not happen while we are on the highway. Acura also stated that maybe the wiring to the battery was stretched and I had to pay to replace it. I have never had to replace that wire. I believe the bluetooth and its controls are a defective design but Acura does not want to admit it.

Related to hands free link which hasn't work in two years. I have replaced the battery several times (once twice one week, under warranty). I replaced the battery a week ago and ask them to please reset hands free link (a request I make every time the car is serviced) and my car nav flickers now. Two day ago the car momentarily lost power while I was driving in town!!!!!!! I was fortunate to be on street with 35mph speed limit and no other cars. It was terrifying.

Constantly having electrical problems. We went on a vacation and came back to find the battery completely dead. Took it in and they diagnosed the problem as a bad hands free unit which was replaced. Now we are having all kinds of electrical problems. Each time we turn the car on the auto setting toggle between driver 1 and driver 2 settings. Occasionally you hear a pop on the speakers when you start the engine. Now we have the check airbag system light come on and won't go off. This car has been a money pit with electrical problems that nobody seems to be able to diagnose. We have spent over $1000 trying to figure it out with no luck.

1.today when I went outside to start my 2007 MDX, the "check starter system" lit up. I waited about 30 seconds and tried again, my vehicle started up. Got to work 1 hour later, turned car off and back on without issue. Hoping it starts after work. This problem just seemed to happen out of no where. My battery is fine but did have problems about 8 months ago where I ended up have to pay approximately $300 to have battery cables/connector replaced by the Acura dealership. The fuse in the cable or connector went bad.

Car constantly loses power or get warning light stating I need to check my starting system. Have replaced the battery 3 times this year, replaced the alternator twice and have replaced the starter once. Sometimes car does not lose power all the way, but will lose functionality of windows, turn signals, windshield wipers, radio, ac and any other function although car will still drive. Inside the arm rest is usually extremely hot when this happens. So hot that it burns your hand to the touch. After reading over 20 complaints on this same type of issue, it seems to be caused by the handsfree link in the car, which I have not been able to use because it stopped working completely back in March 2014. This issue needs to be recalled before someone is seriously injured or worse!

Battery in our 2007 Acura MDX has had to be replaced 3 times in the past couple of months! turns out that the handsfree link module was draining the battery and causing it having to be replaced numerous times. This could cause a fire which can pose as a deadly result especially if the car is parked inside of a garage. This needs to be replaced by Acura free of charge asap! I disconnected it rather than replacing it after reading the numerous complaints on this matter!

Came out to our 2007 MDX in the morning and found that the battery was completely dead for third time in a week. Charged battery again and drove the car to dealership. Problem diagnosed as an open circuit in the hands free unit even when ignition is off. Replaced the hands free unit. Approximately 60 days later, same problem again, and new hands free unit again the problem. The unit is located in the console between front seats was very hot and could have caused a fire. Dealership informed me that they had seen this problem a lot, but that there is no recall and Acura has no answers for them. Had to replace battery after 2nd unit failed, now working on 3rd hands free unit in less than one year. After 2nd incident I contacted Acura and reported the problem and they stated that they were unaware of any problems with these hands free units. Apparently, Acura does not yet have the ability to access the internet as a considerable number of other 2007 MDX owners have voiced the same concern in the Acura owners forum after experiencing failures of their hands free units. Obviously, the hands free unit manufactured by johnson controls has a design defect which is causing this problem and creating a fire risk in the passenger cabin even when ignition is off. Defect could also cause house fire if car is parked in an attached garage due to the fact that the circuit is open even when the ignition is off and gets very hot to the touch. This problem needs to be investigated by N.H.T.S.a., as it is a significant fire safety risk. I encourage all parties who have experienced a similar problem to file a complaint here so that the scope of the problem can be better determined and Acura will be forced to take this problem seriously.

Battery was found to be completely drained on a few occasions after sitting off overnight. After examining possible culprits when the batter was found drained it was found that the handsfree module located in the rear of the center console was hot to the touch. After removing the module completely and recharging the battery this incident of battery drainage has not occurred in 3 months. The handsfree module that operates the bluetooth and handfee functions of the care is defective to the point that it pulls a constant load from the battery even when the car is shut off and keys are not in the ignition. Searching the internet finds many other owners of the same model to have the same problem. This module should be replaced by the manufacturer free of charge because it can lead to a dead battery with no way to start the car, as well as possible fire from the amount of heat built up in the faulty module.
