“Car had been sitting in the driveway for 2 full days with no use. I walked outside to place trash in trash bin and noticed smoke coming from the drivers door. I quickly ran inside, grabbed fire extinguisher and put out the fire.it looks like the fire originated at the window motor or the window switch panel on the drivers side door.”

“I was driving my car close to home and I was traveling at a speed of about 30 MPH. I heard a few taps and then turned off the heating/air conditioning. As I pulled into my driveway, the noise resumed and a burning electrical smell started and actually the smell remained the entire night. I had it towed the next day to my local automotive repair place and as it currently stands the clutch burned up in the compressor and the car is not drivable. I called the dealership, russel, in baltimore and asked if there had been these problems and I was told no. …”

“Mazda CX-7 2008; I purchased the car in september 2007 and it currently has 19,908 miles. The AC is breaking down. While I'm driving on the highway at 65mph, the pressure or high AC air pressure drops and hot air comes out. I also experienced burning smoke coming through the vents. I had the car inspected by the dealer back on august 3, 2012 and they replaced the valve cover. On september 1, 2012 I was driving again on the highway with my family and we experienced the same problem. The AC pressure dropped, hot air was flowing out of the AC and we smelled burning smoke. …”

“The oil light and engine light on my car came on the evening of june 8, 2010, and stalled immediately. That night I poured 5 quarts of oil into my engine. The fault was eventually discovered to be a missing gasket at the oil filter cap which allowed oil to seep out of the car nonstop since my last oil change. I do not understand why the oil light only came on after there was virtually no oil left in the car. If I had been on a highway at the time, I would have had almost no warning before my engine died out on me. Now, the entire engine has to be replaced because it ran for 2 miles with oil.”
