Front seat backs get extremely hot after running the cooling feature for an extended amount of time. It appears to be a result of poor exhaust plumbing from the heat exchange system. When the system creates cool air for the seat it also creates a stream of heated air, this heated air is dumped into the rear of the seat back and accumulates getting hotter and hotter. This results in poor efficiency of the system. The driver's back starts to be heated rather than cooled which may be a safety hazard if it results in the driver's lack of concentration. The system may overheat if left on too long (I never left it on long enough to test). Also, if long items are kept in the pocket along the back of the seat, they may get hot enough to cause injury to someone who touches them.

Seat headrest protrudes too much out of the seat and it pushes forward head of some drivers. The only adjustments available (slide up and down, tilt top forward) do nothing to alleviate the issue. The lack of ability to "scoot" the entire headrest backwards causes back and neck pain while driving for as little as 10 minutes. One solution people are resorting to is to re-insert the headrest backwards, but the tilting mechanism prevent the head from being stopped and sent backwards in the event of an accident. Another solution is to recline the seat back so much that your back is no longer supported. Again a safety issue. When hitting small imperfection on the road, even in dry weather, the vehicle feels as if it's about to fishtail. Some people have mention the suspension is too slow to compensate for bumps and thus the tire, for a small amount of time, does lose contact with the road. All of this complaints can be found in the F-105 forums: www.F150forum.com/F118/
