Back seat got warm & later that morning car engine would not start but lights in vehicle came on. Appt made w/dealer who after a week hadn't done diagnostics nor checked battery & main hybrid fuse as I had requested. I towed to a service garage who upon starting to open the box covering battery, found battery had kindof exploded & bulged. I searched online for recalls on 12/7/22 and found a recall 11/10/22 -22V836000 (KIAs # is SC256) which is "Main Relay within Power Relay Assembly (PRA) may have inadequate connections between its contacts, causing increased electrical resistance, which can overheat the rear seats." "This recall supersedes NHTSA recall number 18V-666. Vehicles already repaired under the previous recall will need to have the new remedy completed" I have receipt showing I had did the 1st recall but the recall is not showing up when I search my VIN#. Kia has found some dealers lied & never replaced the part they said they did. My car will be towed tomorrow to a KIA dealer who will look into this issue & what my battery looks like. No warning lights came on prior to the engine not starting. I called KIA cust service for recalls this morning 12/7 and they were no help to me at all seeing the recall isnt showing under my VIN number.

While parked and engine off, the transmission slipped out of park and rolled back into another vehicle. No one was in the vehicle at the time. When I returned to the vehicle, it was still showing it in park and off.

While driving my 2017 Kia niro on regular roads, it had a dramatic down shift in first gear from a stop. Continued four more stops when approaching a hill, the sport mode did not work and barely made it up hill, no check engine or other lights. Shop couldn't recreate problem. The recalibrated the transmission. Drove fine 1 day. 3/4 of my way on 200 mile trip on highway using cruise control the hev light, check engine and blinking green car came on. Dealer replaced the hybrid system fuse. 5 days later on 74 mile tripp's highway engine, (!) and traction control came on, lost power and barely made it up a hill. Oh and the hood popped open, held by latch while doing 65 on highway. Now it sits at the dealership

The acceleration rapidly fluctuates and it feels like it is vibrating.

I had this car 2 months when I realized I am not getting mpg and also the transmission is jerking off. Mpg on highway is about 35 mpg and about 40 in street. About transmission every time I am about slowing down I hear noise from underneath of car and some times I feel shake, and also few times very hard kick. I have brought this issue with service at carson, and glendale Kia and both service rep gave me same answer about this clutch is computer and it is normal if jerks. And also once I asked service tech to drive the car and he said same thing.
