DETROIT, MI — A spokesperson for Generic Motors confirmed today that the company will be recalling approximately 2.34 million vehicles built between 2008 and 2013 for a defect in which activating the seat heaters can cause a certain chemical reaction in the driver and passenger seats, leading to sudden changes in the foam seat padding and spring structure that can lead to a loss of control.
0. Engineering Division, Generic Motors — “Tell me how this happens again?”
“It’s complicated. Sort of. When you hit the seat heater button twice in a row within a second or so, the controller shorts out and causes the heating element to leak one of the chemicals into the foam. It makes the foam heat to about 500 degrees Celsius, at which point it escapes the seat through, ah, the circular aperture in the spring plate.”
“Which, ah, means that there’s what you can think of as a hot jet of, well, a plasma kind of foam, almost, that exits in a columnar fashion from the top of the lower seat bolster near where it joins the hinge.”
