Loose steering and bad acceleration after hitting potholes

[Dezso3]

I drive a '13 Civic LX. The other week, I hit at least 5 or 6 potholes before the town that I live in had a chance to fill all of them in on its main roadways. Unfortunately, after I hit them, the steering on my car began to feel too loose, and the acceleration also became more sluggish. I took it to the dealership, but the mechanic checked it out and he told me that there was nothing wrong with it. I feel like he overlooked the problems on my car because I am positive that the steering does not feel normal, and neither does the rate of acceleration. :(
