general problems of the 2009 Acura TL

I've had my vehicle stop in the middle of the road due to a mechanical recall that went undiagnosed. ( over oil consumption recall, in which I was completely unaware until finally receiving the letter prodivided) I was driving off of pleasant street in hanson MA, crossing onto the main road when my vehicle engine just shut down and froze the steering wheel. Also a police officer was on the scene to help me safely off the road. I have been calling Acura of Honda and they have been running me in circles with numerous people on the phone and denied that they are willing to cover this problem, and this is a major safety issue. Which the claim safety is first and for the client, but they have failed to deliver on their own words in the safety recall. The car is currently down in hopes that they supply a repair since they have been much aware of this issue, any help would be much appreciated. Thank you.

Vehicle occasionally hesitates, very heavily, when accelerating uphill, like on freeway entrance ramps. When trying to accelerate abruptly, or from first of second gear, it feels like the transmission is down shifting, which could be dangerous in certain situations or when using a freeway entrance ramp in heavy traffic.
