When using the heater or air conditioner a toxic smell fills the cab causing metallic taste and occupants to have a headache. The factory says that they are aware of the problem and have even applied a star case number [xxx] with a release date of 10/24/2013. They say that the issue is bothersome but has no effect on durability or longevity of the cooling system. This is not my concern. My concern is, this toxic smell causing long term health problems or cancer? I have read many forums on the subject some dating back to March 2013.

Started having odor in cab making me dizzy and sick. Got progressively worse for next 900 mile. I brought back to dealer and factory told him to run it for 2 days. Two days later I got it back less a half a tank of gas. Problem seem to be solved. Two day later same thing got sick and complaint was then raised to next level. Factory checked it and said its normal to burn off. I now have 4500 miles on it with 113 hours on the engine and it still making me sick and burning off. After being sick 4 times due to the fumes I had enough. On May 21 they acknowledged my request for the msds on the cosmoline they sprayed on my engine and exhaust. As of June 21 I still have not received a copy of it. I am waiting for my blood test for gases to come in to see what is in the fumes that is causing me to react to the fumes. I had to cut short my vacation due to being sick again from the truck since I can only drive the truck in clear conditions with the windows open. It rain for two days when I got sick last. The factory has offered no solution to the problem. The only thing I could find on cosmoline was it should not be exposed to heat since it breaks down as CO2. This is not a good thing building up in the cab of the truck.
