12 volt starting battery (Lithium Ion Polymer) pn 37507-G2120. battery swollen and will not take charge (2.5 years old) 15,000 miles on vehicle. This battery powers dash and all related safety systems. Dealer refuses to look into problem as batteries are on national back order status and cannot fix due to parts availability. 3 dealerships have been contacted, all have been making excuses for other systems at fault to avoid recognizing battery is defective. I have been without use since Mar2021.

Multiple problems with transmission and electrical. Electrical: 1) While traveling 80mph in the far left lane of the highway, I had to make a hard break when someone changed lanes and moved into my path. When I did that, the car turned off completely. (The key fob was still secured in my cup holder.) I could no longer accelerate and it was slowing down quickly. There was no way for me to turn the car back on using the start button. I could do nothing but try to cross 6 lanes of oncoming traffic to get to the roadside in order to stop, which was extremely dangerous on a busy highway. I was very luck I didn't get slammed from behind and end up in a horrible accident. Once I got to the roadside, I stopped the car and was able to re-start it. Kia mechanics said a diagnostic turned up nothing, and they could not "duplicate" the problem. Of course, they can't guarantee it won't happen again. 2) Another time, I turned off the car after parking, grabbed my key and exited the vehicle. It started loudly beeping at me. It's the sound it make when the key fob is taken from the car while it's on, or you try to lock the car and leave when it's still on. I had to turn the car back on and then back off in order to resolve the issue. Transmission: Transmission was replaced at 19,000 miles because the gears were grinding when I was downshifting and it wasn't shifting from 3rd to 4th well. I'd put my foot on the gas and it just wouldn't go, and then it would finally kick in. I was also having issues with it when parking or coming to a stop. It would get to a point when the car was slowing down and should now coast slowly, and instead, it would come to a sudden stop, then it would jerk forward. When on any kind of an incline, it would stop, roll backward, then catch and roll forward. It seems to suddenly shift into neutral when I'm not in neutral and it should be moving forward. New transmission addressed grinding, but other issues remain. I also multiple issues accelerating now. On May 12, after driving the car to a nearby sto

Since the beginning of April 2021, and just after the odometer turned over to 10K miles, my E-Niro has been experiencing a bizarre behavior that poses a potentially serious safety risk. This takes the form of total loss of acceleration power for a few seconds, usually after deaccelerating to a near stop (usually, but not always, when using the paddle on the left side of the steering wheel to regeneratively brake) then pressing the accelerator pedal, or when making a very tight turn (e.g., into a parking space). Power returns a few seconds after the pause, and I can continue. I have been driving this vehicle for almost 2 years, and there has been nothing similar happen prior to the start of this behavior at the beginning of April. The vehicle has been garaged and charged normally and no extreme weather conditions or other factors had been present before this was first noticed. Instances now seem to be increasing in frequency the past couple of weeks, however. On 2 or 3 occasions, the vehicle actually backed up a couple of feet (on level ground), which was frightening both for me and the auto behind me and could have resulted in an accident. On the other occasions, being momentarily unable to accelerate is also concerning (for instance when it dies halfway into a traffic circle or in an intersection when starting to make a turn). Although no warning lights were initially seen, I now get a "check electrical system" warning when this power loss happens, sometimes even when there has been no loss of power to the motor. The warning light disappears after the vehicle has been turned off and only reappears when another incident occurs. I have asked the dealership service department about this, with no firm response yet. I'm reporting to document this in the event others experience this problem.
