I was sitting in my living room the other day and heard a loud hiss. I though it was my air compressor so I went out to check it out couldn’t find anything wrong. They were also doing road work so I blamed on the road work...anyway fast forward two days, I get three warning on the panel. One for service air suspension, service air brake and something else. The Rebel is stuck in the entry/exit level and will not go up. I just purchased it 5 months ago, and this is not cold weather related as it was 90 degree outside the day I heard the hiss from the air suspension. Of course when I call the dealership, they have never heard of any problems ever with any air suspensions systems on the RAM truck lines. (they wonder why I don't trust them)...and this is why I will never own a RAM again. In fact I'm about ready to sell this one. Just waiting for a certain company to make a truck. Then I'm all in...
