“On saturday, june 2, 2018, I was driving north on interstate 95 and my console lights started blinking and the car just turned off. Luckily, I was able to coast over to the shoulder and watched as the console lights blinked--vsa, brake, information light navigation system screen turned on and off repeatedly, and speedometer and rmp gauges went crazy. I sat on the shoulder and the console lights and navigation system lights continued to blink on and off, and then I saw that the system reset as if the battery had been disconnected. …”

“Battery was replaced in february 2017 (about 7 months ago). Today, everything electrical just died while I was driving. Thank god my children were not in the car & that I was 1 minute from home. The internal lights flickered and then all lights, the radio, and any other electrical portion went dead. The car was still running, but sensing something was wrong, I immediately called my husband and told him to meet me. After I stopped the car, it went dead and never turned on. We have tried numerous approaches to fix and having found the solution yet. …”

“This vehicle is having electrical issue in which is affect various parts, including the deceleration of the vehicle. There are times in which the brake is pressed and instead of the vehicle does not respond to start to slow down. The brakes on the truck have replaced along with tires and yet the problem does continues. This a daily thing that happens it is more noticible when the vehicle reached above 65 and above miles. I have almost got into an accident due to this.”

“My 2008 MDX's battery would drain out often and had to replace 2-3 new batteries during that time frame and numerous jump start. Recently, I just changed battery and had to jump start again within a month. I really got frustrated and took the car to car dealer and he said it's an hfl issue which drains your battery out, so I have to pay $200 to disconnect the system or pay $4000 to put a new hfl system. Their is also a class action law suit regarding this issue and another customer at the dealership had the same issue on his 2008 tl. Why doesn't Acura recall and fix the issue??? …”

“The hands free link constantly drains the battery, even when the vehicle is not in use. I have replaced 3 batteries. This issue leaves you stranded and the repair cost by dealers are ridiculous when this is a wide spread issue. My local dealer explained the only way to fix the issue was to remove the hfl module. Why install something on a vehicle if it's not capable of performing the function it is meant to. Also the cd changer constantly get stuck and will not work. Due to this issue I get an error message or a busy message when trying to remove a cd. …”
