“1: My passenger door sensitive door closing sensor is not working 2: my sunroof is off track and makes noises 3: battery cord is corroded. There is no where in the world to get 1 right now apparently. I bought a brand new battery and car still doesn’t pull energy from the battery so I’m scared the car won’t start very soon”
