2009 Acura MDX problems and owner complaints

THIS VEHICLE IS ONLY 2 YEARS AND 2 MONTHS OLD (BOUGHT IN NOV. 2009), YET THE BATTERY KEEPS FAILING (AND THERE WERE NO LIGHTS LEFT ON AFTER THE ENGINE WAS SHUT OFF, AND NOTHING DONE OUT OF THE ORDINARY WITH THE CAR ON THE 3 OCCASIONS THIS WEEK THAT THE "SHUT OFF" OCCURRED).

APPROXIMATELY 3 MONTHS AGO I WENT TO START THE MEDIC AND IT WOULD NOT START. NO LIGHTS OR ANY OTHER ACCESSORIES WERE LEFT ON. THE CAR WAS JUMPED AND STARTED.

THERE MUST BE A DEFECT IN MY 2009 ACURA MDX HEAD RESTRAINT SYSTEM. I BELIEVE IT HAS RESULTED IN OR CONTRIBUTED TO A NECK INJURY . I HAVE HAD NECK PAIN BAD ENOUGH TO REQUIRE FOUR MONTHS OF PHYSICAL THERAPY AND FIVE SURGICAL PROCEDURES. THE HEAD REST FORCES MY NECK AND HEAD INTO AN UNNATURAL FORWARD POSITION. THE HEAD REST ONLY MOVES UP AND DOWN AND NOT FORWARD AND BACK. I AM UNABLE TO ADJUST THE SEAT AND STEERING WHEEL TO ACCOMMODATE FOR THE LACK OF ADJUSTABLE IN THE HEAD REST. *TR

ACURA MDX (2009) VIBRATION ISSUES: SINCE PURCHASING THE VEHICLE NEW, THERE IS A VIBRATION DRIVING AT SPEEDS EXCEEDING 70 MPH. THE VIBRATION CAN BE FELT THROUGH THE CHASIS AND STEERING WHEEL.

THE MANUFACTURER REPRESENTATIVE COULD NOT RESOLVE THE ISSUE INITIALLY, BUT LATER SUGGESTED THE REPLACEMENT OF THE DRIVE SHAFT. THIS WORKED INITIALLY BUT THE PROBLEM HAS RESURFACED AGAIN. I FILED A LEMON LAW CLAIM THAT ACURA HAS NEGLECTED TO RESPOND TO…

I BROUGHT THE CAR INTO THE DEALER BECAUSE I WAS HAVING TRANSMISSION PROBLEMS OR POWER STEERING PROBLEMS. I INDICATED THAT THE CAR MAKES A WHINE AT ABOUT 1500 RPM.

SOME TIMES WHEN GOING DOWN HILL THE CAR DOES NOT UPSHIFT UNTIL THE CAR IS ACCELERATED EVEN THOUGH THE ROAD SLOPE IS ZERO. THE DEALER NEVER INFORMED ME WHEN I BROUGHT THE VEHICLE IN FOR THE ORIGINAL CONCER…

I TOOK MY 2009 MDX INTO ACURA DEALER FOR SHUDDER AT 35-45 MPH AT 68K. SERVICE TECH WROTE UP REPAIR ORDER AS PCM UPDATE. THEY DID NOT DOCUMENT THE SHUDDER COMPLAINT.
