This for a 2002 Grand Cherokee. Auto and 6 cyl. with 47000 miles. I had it in for a oil leak and they said the neutral safety switch was leaking, so they replaced it. They said it is hydraulic switch, I believed them and took home the vehicle. Does this sound correct? From the pictures I found, it may be a hydraulic switch. However, I still have an oil leak, and so for the 3rd time I have brought it back with a oil leak complaint, stating it looks like it is coming from the rear of the engine. I checked the valve cover, clean, so I'm thinking rear main. I wonder what they'll say is the problem this time. I hate bringing my vehicle places to get fixed, but with a warranty why pay to fix it yourself.
