 We were excited to be the first 500X owners in our town. We showed this car off to all our friends and family. A month after purchase, the car started shifting very firm and overheated. After going to the dealer, I was told that there was water in the oil ( telling me that a head was cracked or a seal was bad) we got the car back the next day and was told everything was fine. No notes on the paperwork about water being in the oil. Assuming everything was fine, we took the car back. A week later the car would stall during hard braking or hard acceleration. Today while picking my daughter up from a friends house, the car stalled and would not start for over 2 hours. No help from dealership on this matter as of yet. It could be our car, but after reading other reviews I don't think we're alone in this matter.
