We just picked up our new 07 gt with leather and besides a few small break in bugs it has been great .....with the exception of the heated seats. They appear to only heat up once or twice a day. The dealer tells me they have a temp sensor to shut them off when they reach 28 degrees and that they work fine. My friend has an 07 mazda3 gt w/leather and his seats toast the bunz you can actually tell they cycle. I think the dealer is trying to snow me but I would like some opinions from other people with the heated seats.
