Battery Dead problems of the 2019 Jeep Cherokee

Less than a year into the purchase of a brand new 2019 Jeep Cherokee, the auto start-stop failed completely during daily rides (before then, it used to work perfectly -- at the red light for example). Took it to the dealership service center where I had bought my car from, they told me the feature functions on a separate battery and that they could do nothing crazy but manually (temporarily) recharge whatever battery they were referring to. The service manager also cluelessly told me to give it a few hours after each ride until the battery responsible for the auto start-stop functionality recharges itself. Although I followed their instruction, I got zero result. Today at the time of writing this complaint, it is getting close to two years after my purchase and there occurs another annoying bug: the main battery keeps dying on me every time I want to start the car. Also, the front display shows an "engine temperature hot" message as the battery fails to start the car, although I do not believe the message is relevant since my car had been sitting in a fairly cool spot for at least 10 hours - no reason for any parts of it to get hot while the engine is shut down.

5 out of the last 6 times when I am leaving the house, the engine shuts off when I make a left hand turn. When I restart the engine sounds like the battery is dead. It takes a few seconds, but then the engine finally restarts. I only have had this problem in the morning.

On oct 29 at 19991 mileage,the cell did not start at all and found the battery dead on Jeep Cherokee latitude 2. 4 l 2019 model parked inside the garage. I used the battery charger overnight. On oct 30, I had to call mopar service for jump start as my charger did not work. After jump, the engine clunked and run but flashing all interior light and several warnings such as ,electronic stability control,service 4wd,power brake on dashboard. When I tried to pull out a car from garage and shifted the gear to the rear,"the service transmission restart in park with vehicle at zero speed ' displayed and engine stopped again. Then car was towed to Jeep dealer. On oct 31 the dealer called me and said the car is ready to pick up. At the dealer, they explained the one cell in the battery was bad and replaced to the new battery. Although I asked to explain why the battery damaged so quickly and it there was any vehicle electric system. But they said the the technician checked all system and confirmed all ok. But no explanation was provided why so many warning s displayed on the dashboard.

Vehicle battery died while driving. Has happened 3 times. Happens at low speeds. Power steering is turned off and you must turn car off and turn back on. Very danergous because you can't turn your steering wheel when it is dying so easily could be hit.

First we weren't able to take vehicle home the day we signed the finance papers, 8/19/18, due to battery being dead. We then picked up car on 8/20/18. Kept vehicle till around the 23rd. The Jeep Cherokee turned off in traffic and went into battery protection mode. We had to put car in park and restart. We were almost rear-ended. I then called dealership to talk to salesman and he was busy so I asked for manager who then told me that the salesman would call me back. When I told salesman about the incident I was told to drive with start-stop function off and to wait till next day to see if it did it again. The vehicle didn't start in the morning and then tried second time and it turned on in battery protection mode so I took it in to dealership and was given a loaner. We then picked up Cherokee on or around 8/31/18. We were told the battery was recharged. The Cherokee then started to turn off again in traffic so I took it back on 9/5/18. I was given another loaner. I was then told to pick up Cherokee on 9/18/18. I was told that they didn't find anything and couldn't recreate the incident. Ever since we received the Cherokee back on the 18th we keep the start-stop function off. Now the tire pressure sensors keep coming on and off and the gas is going at a faster rate then before. Not sure if sensors are working correctly. Took car back to dealership on Sunday 10/14/18 and was told to call service the next day because they had no loaners. Today 10/21/18 vehicle turned off while driving out of parking space. Car restarted but do not trust driving this vehicle with my family inside. There has been several times the vehicle didn't accelerate while stepping on the gas pedal.
