   The center infotainment display went completely black, with only the backup camera feed still functioning. There was no audio output at all (radio, navigation prompts, or Bluetooth). The dealer diagnosed and replaced the FAKRA service cables under Acura TSB B23-025, which addresses this exact display-blank/audio failure. After the cable repair, the screen remained black and audio remained completely non-functional. The dealer then determined the tuner/AV control unit had…

   While driving in the rain, after an hour long drive home from Philadelphia back to Reading, taking [XXX] and [XXX], I accelerated my vehicle while going around 50 mph and immediately was faced with a blinking check engine light and lost the ability to accelerate.

   The auto-stop feature on my 2019 Acura RDX has resulted in my car abruptly shutting down twice now -- today it happened when I slowed to a stop at an intersection. Basically, rather than just shutting the engine off while idling, it shuts of the electrical (dashboard and infotainment -- all systems) and engine and then immediately restarts with the car in Park. There was no warning sound or light prior to the car turning off and restarting. Obviously, it is very dangerous…

    This morning I awoke to another shattered rear windshield. I had the exact same thing happen in January of this year. This is my second out of cost rear windshield replacement due to the known problem Acura has failed to address. I have spent over 1,000 dollars on replacement glass in addition to my car being in the shop for 3 months waiting for a fuel pump. This is ridiculous, and something needs to be done.
