While driving I notice that the power steering started to get stiff. While driving further there was no power steering at all. Turning was extremely hard. The hose was just replaced due to a recall, 3 months later power steering pump was sealed due to a leak, a month later power steering went out. This was least expected especially when having those services done which poses a safety issue. I took it to the Acura dealership and told me that steering rack is leaking from seals and need to be replaced. I don't think this type of malfunction should happen to a car of this age and mileage.
