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. …
I purchased a 07 Acura MDX 1 month ago with 115,500 miles and got the extended power train warranty. Hall Nissan pulled the vehicle off hall Acura's lot. They printed out a receipt from all the work Acura did before I bought the car, and ensured me nothing was wrong with it that it went through a 150 point inspection. I took it to Acura 2.5 weeks after I bought it because the check engine light came on and a tranny code popped up. They diagnosed the car and found $7,000 worth of malfunctioning equipment. Transmission range sensor, both front struts, ac coil and magnetic clutch, front cv axle boot leaking, rear shocks, rear sway bar bushings, transmission cooler hose leaking. I have spoken with numerous managers about this, they wont replace the cv axel assembly (suggested fix), the transmission cooler line (suggested fix), or front struts or back shocks which failed upon inspection. …
Engine & cooling
I own a 2007 Acura MDX which has had a number of intermittent electrical problems over the years. I had to replace the handsfree link module a few years ago at the dealer. The yellow check oil level light has come on for no reason for years. It goes on for a second then off. A few months ago the entire electrical system 'fried' and I had to buy a new battery and new alternator. Recently I hear a buzzing sound when I use the turn signals and the hazards do not work at all. Last night the car died on the interstate- the instrument panel went dark, the engine would not accelerate, and I was lucky to be able to get onto the shoulder. I turned off the car and then started it again. When it works there is no problem with the operation but this car is now unreliable and dangerous. …

The active damper system (ads) on my Acura MDX has been malfunctioning and has caused the struts to fail on both the front and rear. Requiring it to be replaced. There are a number of issues related to the ads system that have been identified in respective forums by customers. Acura Canada has extended the warranty till the end of the year (2016), however, Acura America is not willing to acknowledge the defect. I am from Canada, however, my vehicle is from the us and I have had to spend dollars to replace the struts while customers in Canada are getting theirs replaced or reimbursed when there is an issue with the structs owing to the extended warranty.
