Just took a road trip up to the Colorado Rockies, 2 week old 90D with cold weather package, etc. My wife in passenger seat tried the seat warmer as it was in the 50's and rainy outside. She loves her Lexus GX seat warmer and commented that at the first setting level 3, the appropriate areas heated up modestly, but nothing like she feels in her GX. More importantly, after a quick moderate warm up, despite the indicator showing it still on level 3, the warming effect did not maintain itself, but resorted to a lower perceptible temp on her seat and lumbar region. Anyone else try the seat warmers/heaters and have a similar experience where it fades on you, and wont hold a warm enough temp to not have to turn off and restart the warm cycle?
