2007 Acura MDX problems

Filed Jun 3, 2026 · Airbags, Electrical · CA

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 coming on meant the airbags were disabled, or we would have brought the car in sooner.)

As I was driving on 278 headed south traveling at approximately 65mph, the radio shut off as well as the car. There was a warning light that said "Check emission" The ABS light would come on as well I had to try to get the car into the far right lane and restarted the car. I was able to restart the car and made it home with the car periodically completely shutting off. As I was driving the radio would briefly go on and off as well. This was the first time this had happened. The safety issue was that there was absolutely no warning and at the time I was traveling with traffic. There was nothing that could have caused this other than some type of mechanical failure.

The engine does not start at once and when the key is turned off to try again, the engine explodes and the upper part of the engine case is completely torn off. At this time, there was a huge explosion sound like a bomb exploding and a lot of black smoke came out. It's not really a rocket engine, which is a huge force, but I really don't understand how much pressure was applied in the engine of an ordinary car, so that the engine cover was broken by the explosion. Even if a person intentionally smashed the engine cover like this, it would be impossible. If such an accident occurred while running, it is thought that there would have been many casualties. Although it is an old car, it was used without any problems until yesterday, and it is understandable that the car does not start even if there is a problem. I think that such a big engine explosion produced a problematic engine by Honda Acura. There must be various engineering reasons for the explosion, but we believe that it is a problem that should never happen again by identifying the cause, so we report it with photos. Please investigate to find out the cause and prevent further accidents.

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 the federal safety agency 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.

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.
