2007 Acura MDX electrical system problems

“The driver's seat wiring harness on my daughter's 2007 Acura MDX has failed under normal operating conditions. The physical adjustment and movement of the driver's seat causes the factory wiring harness to over-tension and fracture internally. This has resulted in an intermittent, escalating failure of the Supplemental Restraint System (SRS), throwing diagnostic trouble code DTC 71-11 ("open circuit in the driver's seat position sensor"). This is a known manufacturer engineering defect documented under Acura Technical Service Bulletin TSB 11-023. This defect poses an immediate safety hazard because the vehicle's computer automatically disables the driver's side airbag safety deployment when the circuit loses connection. The manufacturer is currently refusing to cover the repair due to the age of the vehicle, despite it being a critical safety-restraint system failure that leaves the driver unprotected in a collision. (The exact date of first onset is estimated, as this safety defect is an ongoing, intermittent electrical failure that began several months ago but only recently became more frequent. We also were originally unaware that the airbag warning light…”

“TL* THE CONTACT OWNS A 2007 ACURA MDX. THE CONTACT STATED THAT THE VEHICLE EXPERIENCED ELECTRICAL FAILURES WHERE THE POWER DOORS UNLOCK AND LOCK WITHOUT WARNING. ADDITIONALLY, THE WINDOWS WOULD RAISE AND LOWER WITHOUT WARNING. THE VEHICLE WOULD LOSE POWER WITHOUT WARNING. THE VEHICLE WAS NOT TAKEN TO A DEALER OR INDEPENDENT MECHANIC TO BE DIAGNOSED.

WHILE DRIVING THE CAR WILL JUMP INTO GEAR AS I AM ACCELERATING.”

“OVER THE PAST TWO YEARS HAVE HAD TO INEXPLICABLY JUMP MDX WHEN IT FAILS TO START, USUALLY AFTER SITTING OVER NIGHT. (CONFIRMED NO AUXILIARY POWER LEFT ON.) WILL BE FINE FOR A PERIOD OF TIME, AND SYMPTOMS REAPPEAR. HAVE NOW CHANGED BATTERY TWICE IN PAST YEAR. FOUR MONTHS AFTER MOST RECENT BATTERY CHANGE, BATTERY WAS DEAD AGAIN. THIS TIME AFTER JUMPED THE CAR THREW SOME ADDITIONAL WARNING LIGHTS AROUND CHARGING SYSTEM. AFTER TRYING TO RETURN TO THE PARKING SPACE, THE CAR STARTED WAS NOT DRIVING PROPERLY, SEEMS TO BE ELECTRICAL. AFTER READING FORUMS ONLINE MY SYMPTOMS MATCH VERY CLOSELY TO OTHERS THAT HAVE A HANDSFREELINK ISSUE ON THIS MODEL MDX. (PARASITIC POWER DRAW.) CONTACTING ACURA TODAY, AS THIS TIME THE CAR IS NOT DRIVE-ABLE.”
