Hey guys I have a 2015 Ram 1500 Sport bought brand new. At 30,000kms I started noticing that the the front driver and passenger seats are starting to bubble. Seems like the leather has expanded/stretched. I called the dealership and Chrysler Canada to get it fixed but they rejected it stating it is because of an "external defect". I asked them what do you mean by that and they said you guys must have put heavy objects on the seats. So now I am not sure exactly what to do. Any thoughts!!??
