Problems documented internally thru service calls, oil changes, tire rotations at Acura dealership for years. Car sold by a dealership to auction & onto me through another used car dealer. Drove 2006 MDX 1,000 miles, to around 160,000 then heard noise in right front car area, when going over bumpy road. Checked & found car sold with 2 open recalls, airbag & shift interlock both safety hazards. Took to another Acura dealership for maint. evaluation & fixing recalls. I Found many technical service bulletins on fixing various serious problems that were never done. Now, due to under reporting actual customer problems/trends as required legally; I need torque convertor, new transmission, motor mounts broken, oil pump leaking, front struts needed etc. etc. $9,000 cost. plus loss of price paid for car. Beware problems have continued from models 2000 & on. Manufacturing design responsibilities to inform, fix, report, then reimburse customers. Honda/Acura fined & lost several suits exceeding 200 million & rising. No remedy yet for me & others who had to pay for same problems repeatedly, when TSB's indicated real causes for customer problems & remedies never offered owners unless they find out on their own.
