Example complaints

Brakes: “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. …”

NHTSA complaint #10279740, filed 2009-08, 54,500 miles

Electrical system: “Vehicle had been driven approximately 2 miles from start time, was stationary and unoccupied for approximately 10-25 minutes. Vehicle interior caught fire at the base of the top sitting area of the rear seat, flames from fire melted the over head interior light and ignited a fire on the head liner, which caused the fire to spread under neath the headliner and roof of the vehicle, melting the exterior paint. There was no prior indication of burning when driving or after parking the vehicle prior to the fire. …”

NHTSA complaint #10893801, filed 2016-08, 120,000 miles

Suspension: “The other day I took a ride in my truck and upon driving approximately two blocks from my home the steering control of the car totally failed. Imagine driving your car and at some point, you lose the capability of controlling your cars direction while holding your steering wheel. One can only imagine if I was going 65 miles an hour and driving on a highway then losing the ability to turn your wheels. I am blessed this malfunction happened when I was only traveling 10 miles an hour. …”
