My dodge challenger just started having a strange issue today. I came home to my trunk popped, and I thought maybe my kid had popped the trunk with the key fob before we left. I just shut the trunk, and I cranked the car to make sure it wasn't dead. It was fine. So, I get out, and I shut my door. The trunk pops. I shut it again, and I lock my car. The trunk pops. I shut it again, and I unlock and lock the door. Trunk pops. Shut it, lock it. Everything's fine, I go to walk away and go inside. Everything is fine. I get to my front door, and I hear my trunk pop. I've finally got everything shut and locked. Everything seems to be normal, it hasn't popped again. What could be happened? What could be a solution. I've already spent 2k repairing this car- oxygen sensors, catalytic converters, etc.... nowwww this.
