Hfl module # 39770-stx-a011-m1 stopped working preventing connection to my cell phone. 2009 mdx with 92,004 miles. Called all the dealerships in my area and others on the internet and no one has the module. I was told by them it's on national back order for sone time now ( 2/5/2020 ) . Doing further research brought to light there is a 2016 or 2017 class action suit on this hfl module/system failing and draining power from the battery, causing premature failure of said battery, which also happened to me as well as no start conditions which also has happened to me. So far no stall outs with the vehicle moving. I currently have a hfl module on order from acura and was told because their on back order it could be several months before they get their order. Also they want my old module which they added a $50.00 core charge to the price. Though there maybe just a few official complaints listed here just check the web. There is obviously a fault in these modules and the manufacture is either doing reverse failure analysis on the returned modules or wirse yet fixing the broken ones and sending them out as the replacements. Either way they obviously know is wrong with these modules. This module is not what is considered a normal attrition piece like tires, brakes, light bulbs , belts , hoses. When was the last time you planned on replacing a broken radio in your vehicle, you don't. I shouldn't have to plan or pay to replace my hfl module, quality control and manufacture loyalty to their customers is abismal.

Bluetooth stopped working and a few weeks later, my car wouldn't start. I replaced the battery and a few days later the car stalled on me as I was pulling out of my spot!!!!! I went to the acura dealer and explained to the guy that my battery kept draining. He asked me if my bluetooth stopped working, I was shocked because I hadn't mentioned any issues with my bluetooth but I let him know that in fact, the bluetooth had stopped. The rep said it's a common problem in my vehicle. Had to replace the bluetooth and paid $600!!!! My friends sister has the same make car and her bluetooth stopped working and her car battery keeps going dead. It's very scary since apparently I must have started the car right before the battery died again. Imagine what would've happened if it had stalled on a highway or a busy street!

While driving on the brooklyn-queens expressway (I 278 e)at a high rate of speed the car stalled nearly causing an accident, truck and tractor trailers came barreling down towards my stalled vehicle and abruptly changing lanes to avoid crashing into my car. I dialed 911 and the nypd highway unit sent a towtruck immediately to avoid accidents (I was petrified waiting for the tow) the dealer identified a throttle failure, replaced the throttle again for the second time.
