NHTSA Complaint #11626148 — 2024 KIA EV6

I've had to have my rental car jumped 3 times now, the check engine light has been on since I rented it, had to be reset and is now back on. I believe it's the 12v battery, it pops up warnings of battery discharge almost daily. All 3 times it was shut off and when I went to start it, it wouldn't turn on, 3 seperate people have jumped it for me now in 3 different locations, the last one being while I was working and had to end the delivery because my car would not start so I am now unable to work as they have paused my deliveries until my account is reviewed. I am putting the first date I noticed the check engine light, which was the day I rented the vehicle. The not starting has happened on the following dates: [XXX], [XXX] and today [XXX]. I recall noticing the battery discharge warning for the first time around the beginning of Oct, maybe closer to mid October. I rented it from hertz Uber rentals in Phoenix, AZ so I could work doing deliveries and rides. I have had it jumped twice in Phoenix and once in Prescott, AZ.
