I had heard a wheezing noise in the front end so I took the car to my mechanic. He was unable to find a problem. A week after while driving the car I was driving and as I turned the car completely shut down. Two days later it began to not drive properly I took the car back to the mechanic and said I had a bad sensor but the water pump was going bad. He stated it shouldn't go bad in this newer of a car. My car has been undrivable ever since. I've called around to get it fixed as though it seems nobody has the proper tools to fix this issue due to the fact the whole engine needs to be removed to fix the problem.
Steering is very heavy and sometimes fails completely especially when slowing down to a stop. It is most pronounced when slowing into a curve. The power steering pump also becomes noticeably louder. This is an ongoing problem since buying the car 2 months ago.
