When I shifted into reverse the back up camera wouldn’t come on and instead a screen that said check your surroundings stayed on the screen. I reset it using the 3 button reset method and it came back on. Drove it to the grocery store, and then it sat in my driveway for 3 hours. When I went to go back in to town, the car was completely dead. No power whatsoever. We tried jumper cables and those didn’t work. Finally tried a battery charger and after an hour of charging it finally came back on. A car this new shouldn’t be having these issues.

Car showed ignition on when the car was turned off. Same day while driving on highway car engine revved for no reason. Also when someone got out of parked car it said no key detected but car was still turned on and key was right beside me.
Cpsc: the manufacturer sells a smart car seat. *dt the consumer stated the cybex sironsafe 2.0 car seats plug into the vehicles obd ports. The car seats both individually drained the battery of the vehicle. The manufacturer was made aware of the failure but, did not offer any assistance.
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.
While driving the vehicle the car to an abrupt stop and I had no control. The dashboard lit up with all types of warnings and heat was coming from the front of the car.
