We drove from Cincinnati, OH to Wray, Co for Christmas. We drove 15 hrs straight back home ( gas and potty breaks). I drove the last 9 hrs. I have fibromyalgia and osteoarthritis. So the heated seats are wonderful - usually. Yes, I used the heated seats almost all the way. Iâm always hurting so I didnât notice a problem. On our last gas stop I told my husband I must have been sweating because I felt like I had a heat rash. We got home at 3 am and my husband said it looked more like a burn. It was painful and when I looked at it I saw blisters. Next morning it was more painful and red and ugly looking. I called Ford Corporate to give them a heads up that there was an issue with their heated seats. They stated they couldnât help. Sorry I got hurt. Take it to local service and let them know. Called Ford service - they can get me in on Jan 17 and I have to pay for it. I just want someone aware that their heated seats can cause severe burns. Btw. The burn is on my upper right thigh.
