I have a 2010 Grand Cherokee Laredo. The other day when i pulled into the grocery store and parked my dash dinged and said check gauges. My temperature gauge was on hot. So i turned it off did my shopping and waited for it to cool off. Attempted to start it and my starter did nothing. No sounds or anything. Just silence. Coolant was fine, oil looked good. I dont understand what it could be besides it did overheat.
