I have been experiencing pretty much every recall that is on the list number one it started with my car check engine light coming on. And the codes that kept on coming up or for the plugs and coils. I would replace them and they would just go bad again in like a week it is causing my car to do what seems like it's misfiring. My tire light is stuck on when the tires are fine. The speed control stops working on and off. When I steer there's a loud clicking noise. Whenever I try to shift here lately sometimes it won't go into gear. When I turn on the AC it will cause the car to misfire and the only way to make it stop is to turn off the AC and restart the car sometimes three to four times before it stops messing up.today the scariest thing of all happened I was pulling out of bronze and white smoke billowed out of the car tailpipes I'm not sure why. The car is also sporadically not going in gear when I am on the highway making me worry that me and my five kids are in danger due to someone raikkonen to me because my car will not go up to speed and will not shift into the right gear and misfires and will not go over like 30 miles per hour and putz. I replace parts and it seems to work well for a week or two but my car is not on the recall list they say that every single thing that is on the recall list is happening to my car. I don't know what to do about all of this I honestly you just think that dart needs to take the car back.. Like recall it completely. This car has been nothing but trouble after the first year of driving it.
