“This Mazda CX-7 has been driven by my disabled finance and used for in city driving it's whole life and one day a high pitched whining sound developed and the car was delivered to capitol Mazda for an inspection. Upon getting the results we were told that the car had not had regular servicing at the dealer. I agreed as I am an engineer and do most servicing of my families vehicles. They said I had not done the oil changes, but I had done them every 5,000 miles. Every vehicle I have ever owned had more than 200,000 mile on them when I sold them. …”

In the middle of this blinding smoke, surrounded by huge trucks, I lost aceleration. My instrumentation panel did not have any warning lights on. I was driving blind. I pulled off the highway as quickly as possible, and had my car towed to a dealership. The dealership said my turbo blew out, (which I guess sucked all the oil out of the car) I need a vvt valve and the timing chain is stretched. …”

I had the care towed into the same dealership I bought the car at, and come to find out the transmission went out on the car. I took the car into the dealership on friday, december 12, 2008. I was told that I would receive a call from someone on monday, I waited and finally went to the dealership my self and they had no answers about the car. …”
