I have a ’03 Acura MDX, with seat heaters on both the driver and front pass seats. In the past year the driver’s side seat heater has developed a "hot spot". There is just one certain spot that becomes hotter than the rest, in either the low or high setting, and it literally burns my leg. I took it to the dealership, the vehicle is under warranty, and they are telling me they cannot detect a variance with their "infared heat sensors" and they will have to take the seat completely apart, and if they still cannot find anything wrong with it, I will have to pay the labor!!! I am not imagining this. When I checked my vehicle into service this morning I told the person who was checking me in, not the same guy who was in charge of my vehicle…they couldnt find him, about this "hot spot" and he told me this does occur when the heater is about to go out. This needs to be fixed under warranty, and I need to be armed with as much info as possible. Suggestions or shared experience will help!
