Car has warning message and several engine lights on dash come up and asks to stop car and check the regenerative brake system. Car loses all systems that are electrical, car is very hard to drive, even not operative. This has happened many times over the past four years. Each time the car has been taken to a authorized KIA Dealership and they have not been able to fix the problem. It happened almost a week ago and dealership told us that they couldn't find anything wrong and were told to pick it up. Happened again today and it was while driving. Same issue, same warnings on dash.

KIA NIRO 2019 SAFETY RECALL As described in the safety recall (previous page), my KIA Niro 2019 alarm went off with the following error message "Engine Overheating". Kia of America and its dealership refused to fix the problem. The car dealership -said- has no direction as to how or when to fix the problem, and the KIA consumer hotline is out of business.

I’ve had this repaired by Kia and immediately failed again, but a component to the alternator and ac unit is attached to the drive train and will cause an alarm that hybrid battery failure and sudden power loss(they told me this with the first “fix” but failed within an hour of leaving Kia. It’s happened again tonight and nearly caused a crash on the freeway and I’ve seen many others with this issue and I want to drive my kid home safely so any help would be wonderful with this issue. Thank you!!

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

Starting battery (which operates the safety systems) was getting progressively worse until vehicle could not be started. Upon inspection it was determined that the 1.5 year old starting battery was swollen and defective. NOTE: Vehicle did sit for 12 months in estate litigation.
