I just got my new Kona 2 weeks ago. I really like it except for one big problem, at times it emits a very strong chemical smell into the interior through the vents. It smells like the fertilizer section of a store. As long as the air conditioner is on and cooling it is fine. Say it is set at 70 - when it reaches 70 it begins to emit the odor - it is almost like it is emiting fumes from the battery. Is this normal? More importantly is it safe?
