When I bought my 2nd cla, I have noticed whenever I am driving & turn on the driver's heated seat, that it always burn my left leg, so I would always turn it off. This has been ongoing for quite some time. Fast forward to last night (2/20/21), I turned on my heated seats & I smelled something burning then it felt like my leg was on fire. This time the pain from the burning was worse than the other times. I immediately turned the heated seat off. I could not tell if the seat was giving off smoke because it was dark. I noticed the next day that there were a hole in that area on my drivers seat where the problem occurred. After seeing the hole in my seat, I thank god I turned the heated seat off because had I moved my leg from that burning area on my seat, ignored it & kept driving, I believe the seat would have created a fire! this most definitely screams a fire hazard, unsafe & should be deemed as a recall on all Mercedes.
