“Driver's seat heater shorted out while vehicle was being driven. The event ocurred so quickly and was so severe that it burned through the leather seat upholstery and a very heavy pair of denim jeans I was wearing almost imediately and unexpectedly. The consequences are pretty much obvious and could range from severe burns, to the vehicle burning to causing a serious accident because of the spontaneous happening. No response from mercedes benz to date.”

“The heated seat in my 2003 mercedes ML320 burned through my leather seats and leaving a small mark on my left thigh. My injury healed; however, there is still a burnt mark on my seat. After explaining it to mercedes and my extended warranty service, both decided to help me stating it was a cosmetic defect. Now I'm stuck with a driver side seat that has 3 cm hole in it along with heated seats that mercedes suggest that I should never turn on, even though I paid extra for it.”

NHTSA complaint #10144571, filed 2005-12

“I own a 2003 mercedes ML320, while I was driving w/the heated seats on I started to notice a burning odor. The odor got stronger & it smelt like burning plastic. I noticed my rear was starting to get a tad too warm so I put my hand down on the seat & almost burn my hand. I immediately turned off the seat warmer & called mercedes the following morning to arrange for service. When I arrived at mercedes the manager informed me that this was not the first incident & that a gentlemens suit had been replaced b/c it burnt through his clothing. …”
