Electrical system

“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…”

Steering

“MY 2007 ACURA MDX IS EXPERIENCING A COMMON PROBLEM WITH THE POWER STEERING PUMP. ACURA ISSUED AN EXTENSION ON THE WARRANTY FOR THIS ISSUE, BUT THAT EXTENSION ONLY LASTED SEVEN YEARS. AS SOMEONE WHO ACQUIRED THE CAR AFTER 2014 I WAS AUTOMATICALLY NOT QUALIFIED IN THIS COMMON PROBLEM. ACURA HAS ISSUED A RECALL FOR OTHER MODEL CARS BUILT IN THIS SAME YEAR USING THE SAME POWER STEERING PUMP. YET THE RECALL NHTSA CAMPAIGN ID: 12V222000 DOES NOT INCLUDE MODEL MDX. I WOULD LIKE TO KNOW "WHY" MDX WAS NOT ALSO PART OF THE RECALL SEEING AS THOUGH IT IS THE EXACT SAME SYMPTOMS, AND PARTS USED FOR THE POWER STEERING PUMP, HOSES, AND SEALS.”

I AM SIMPLY CONDUCTING MY DUE DILIGENCE IN REPORTING MY VEHICLE AS IT HAS BECOME MY PROPERTY AND HENCE, MY NEW PROBLEM.”
