I have 07 H3 had a ground wire issue. Acted like battery was dead all the time. Would do really fast clicking sound like the starter was bad. We ran a ground wire from the N post to the alternator bracket and bolted on. Fixed the issues hope this might help. Now I'm trying find a answer to the trans. Acta like it's in N after you get 3 miles down road. Turn truck off back on and it's ok for ½ mile and it does it again. It's ok if you let it sit I've night but after it gets warmed up it acts like it's in N again. Going to replace the filter and fluid this weekend. Just hope that fixes it.
