Howdy yall, first post on here longtime lurker, these forums have proven super useful to me, so thanks again and in advance. I got my 06 about a year ago and have put almost 50k miles on it bringing it to 150. 0 complaints at all the car had driven like a dream and I’ve put it through a really rough Colorado winter. I have some questions, nothing to crazy but I just want to get a realistic idea moving forward. I was driving to work a month ago and the car started dying and coming back to life, didn’t know what happened but it died, went to jump it and found my jack connected to my positive post of the battery. Would that cause any major issues? Around the same time as that my parking sensors have stopped working so I think that is one thing. Other than that should I check anything else? I want to put some money back into the car, I’ve taken care of a few minor repairs, nothing major. I got new belts and a new valve gasket, brakes and rotors, o2 sensor, and other minor things. I’ve started to restore the interior best I can as it is thrashed. A list of things wrong in the interior would be; rear pull handle snapped off, every door panel cracked and broken at the lower torx screw, adjustable steering wheel leather cover connectors broken, cargo light need as new connector, some tint is messed up and there are some knicks on the ceiling. As far as mechanically and electronically I don’t think to many things have gone bad. The list would be: dash doesn’t display the oil level, runs out of gas displayed at a qtr tank,
