2014 Acura MDX: complaints, problems and recalls

YESTERDAY, AFTER BACKING UP, STEPPING ON THE BRAKE PEDAL AND COMING TO A COMPLETE STOP, SHIFTED INTO "PARK" WITH MY FOOT STILL ON THE BRAKE PEDAL. THE ENGINE UNEXPECTEDLY REVVED UP TO WHAT SOUNDED LIKE FULL THROTTLE! I PUSHED THE IGNITION BUTTON TO STOP THE ENGINE. AFTER THIS ONE INCIDENT, THE CAR HAS FUNCTIONED NORMALLY. *TR

WHEN COMING TO A SUDDEN STOP THE BRAKE LIGHT WILL FLASH ON THE DASHBOARD ACCOMPANIED BY A BEEPING SOUND FOR APPROXIMATELY 3 SECONDS.

THE INCLUDED INFOTAINMENT SYSTEM, WHICH IS NOW PREDOMINANTLY CONTROLLED BY A TOUCHSCREEN, IS INCREDIBLY SLOW, LAGGY, AND DANGEROUS TO OPERATE. THERE ARE MULTIPLE, ONGOING FAILURES WITH THIS SYSTEM - EVERY TIME I ENTER THE VEHICLE. AS HONDA/ACURA HAS REMOVED OR REPLACED PRIMARY-OPERATION BUTTONS (32 OUT OF 41, BY THEIR COUNT), THE MANDATE TO USE THE OTHER OPERATIONAL SYSTEM (TOUCHSCREEN AND JOG-DIAL) HAS INCREASED THE RISK OF SAFETY INCIDENTS, EXACERBATED BY A SLOW USER INTERFACE RESPONSE AND OFTEN-FAILING VOICE CONTROL SYSTEM.

THE 2014 MDX IS NOW EQUIPPED WITH A DRIVER'S SIDE MIRROR THAT IS SPLIT VERTICALLY INTO TWO PIECES ONE LARGER AND ONE SMALLER. THE SMALLER MIRROR CREATES THE ILLUSION THAT A PASSING CAR IS CRASHING INTO YOUR VEHICLE. IT IS QUITE DISCONCERTING TO A DRIVER. BOTH MYSELF AND MY SON HAVE HAD THIS EXPERIENCE. IT CAUSES A DRIVER TO REACT TO A DANGER THAT DOES NOT EXIST. *TR
