general problems of the 2008 Acura MDX

I was driving my car going about 40 mph when suddenly I lost the ability to steer the car, stop the car, accelerate and cut on my blinkers. Nothing in the car worked. I was desperate to get out of the traffic flow when the car suddenly jerked back on. It did this off and on as I took it to the dealership. Once there they stated that the battery was the issue. Battery was replaced. Various internal components of the car started to fall apart (seat belts, airbags, car lights, car key, window sensors, door locks, alarm, navigation). For a time the car drove but with very stiff handling. Car was taken in for an issue that sounded like a whirring sound at start-up. Everything was replaced to fix the issue with the service technician doing a hail mary attempt at offering resolve. I finally received my car back two weeks later. Then here we go again, I am on the freeway with a brand new battery installed by Acura when everything powers off yet again. Car even braked itself and I saw my life flash before my eyes. I was on the freeway going about 70 mph when this occurred and traffic flow was thick. I took my car to Acura and currently they have had it for over a week. They tell me it is my battery again which they will replace for free but they want to keep for further testing. I work from home and drive my car extended distances when needed and I need reliable transportation. This car is proving unreliable. I am not getting straight answers from anyone and in 4 years I have replaced my battery 3 times! I park in the garage! this is a serious safety concern. I may not be so lucky the next time the power goes out on the car and everything stops working! I see this concern is not an isolated incident and I need help!.

When driving my 2008 Acura Mdx in the rain, specifically if I have gone thru a puddle, simultaneously a message will appear "check battery charge" and I will loose my power steering for about 30 seconds, making it near impossible to steer. This has been happening since I got the car 2 years ago. I have recently been told by the dealership there are many other complaints about this same problem and it is a design flaw that has been corrected in newer models. At present the only solution is drive slower thru puddles so the cables that are exposed under the car do not get wet and therefore the power steering is momentarily lost. I was in the middle of a turn the last time this happened, and it was quite frightening since basically one is losing steering control of the car. My 9 year old daughter was in the back seat. There is no warning when this is going to happen and one does not always know when the car has gone thru a puddle. Furthermore, watching for puddles is a dangerous distraction in a rain storm. I called Acura today as I lost battery power yesterday and had to call roadside assistance and I suspect this is related to the problem I had the week before. They deny any knowledge of the situation even though I was told by the dealership, miami Acura, that they had notified Acura and that Acura fixed the problem in newer models but had no solution for those who were driving these models. I asked them if they were, like Toyota, going to wait until someone died before they would issue a recall. I hope NHTSA will take this seriously and pursue an investigation immediately.
