This vehicle is has been on lease for 1 year and has less than 4000 miles on it. initially while attempting to start the vehicle that had been parked overnight it gave the following warnings: - keyless entry malfunction - charging system malfunction - vehicle overheating - battery malfunction the car would not shut off until i held the start/stop button in for roughly 20secs. the dealer service center took the car and told us the battery had a low charge, charged it and returned it. several weeks later while the vehicle was in motion with 2 adults and 2 children on a city street traveling at about 20mph it gave the following warnings: - keyless entry malfuction - charging system malfuction - vehicle overheating - battery malfunction - pull over to safety at this point the vehicle was still in motion and the stereo, hvac, and power steering cut out. i was able to pull the vehicle over but again had trouble shutting it off. i had to hold the start/stop button for 20-40secs. the car was towed to the dealer service center. we were told by the service center that a lot of 500 vehicles of this year and model had an engine harness defect that no recall had been issued for but they were aware of defect and had a fix for it. i feel i was lucky that i was only traveling 20mph when the power steering cut out. if i had been traveling highway speeds on a bend the situation could have been tragic and i had my children in the car. currently, based on what i've been told by the dealer service and sales managers there are potentially hundreds of other 2018 cx-9s which could experience this same malfunction while in motion.
