I'm also on my 4th one and as soon as i use the heater i will need #5, i can see it starting to lift when it gets warm. Last time i was at the Dealer (for something else) i was looking round the cars for sale and 3 of the GP's they had (2 were new) needed the vent trims replacing. Its about time Fiat did something to rectify this problem once and for all. I'm into my 3rd year warranty now and even though it will be done under warranty next time i don't want to keep buying these trims every six months for the duration of ownership of this car. TIP, don't use your heater and the vent trim will last longer.
