“I purchased a 2006 Hummer H2 at cerritos Hummer. I currently have almost 55,000 miles. Today I was parking my car and noticed the steering was extremely hard to turn. Also the brakes were really weak. I used all the energy I had to get into a gas station driveway. I drove about 1 block because I needed gas where I noticed oil dropping under the car. I checked under the hood and the oil was coming out near the power steering pump. I opened the power steering reservoir and saw that there was very little oil because it had dropped under my car. …”
