“The radio and navigation intermittently go on and off while driving.my ABS,check emission system,shaw-d will go off. Car will shut down while im driving and I lose all power. I lose power to locks, windows and back hatch. Some days when starting the car it wont turn over and start up. Somedays after driving and I turn the car off, I lose all power. While driving the car will jump into gear as I am accelerating.”
NHTSA complaint #11320917, filed 2020-04, 133,000 miles“While driving, the car will frequently lose electrical power. Dash indicator lights come on, the radio shuts off and sometime I'll have to reset the radio and navigation codes. While at a stop light, sometimes depressing the gas pedal does nothing and then suddenly it will begin to move. I'm very concern the unpredictable nature of the problem will cause a wreck if I lose engine power, especially in a curve.”
NHTSA complaint #11243441, filed 2019-08, 131,000 miles“I own a 2007 Acura MDX which has had a number of intermittent electrical problems over the years. I had to replace the handsfree link module a few years ago at the dealer. The yellow check oil level light has come on for no reason for years. It goes on for a second then off. A few months ago the entire electrical system 'fried' and I had to buy a new battery and new alternator. Recently I hear a buzzing sound when I use the turn signals and the hazards do not work at all. …”
NHTSA complaint #11171901, filed 2019-01, 130,000 miles“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.”
NHTSA complaint #10875366, filed 2016-06, 165,000 miles“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.”
