2019 KIA NIRO Electrical System Problems

Hydraulic fluid is leaking onto the hydraulic clutch actuator’s circuit board, creating a potential fire hazard. The vehicle requires replacement of the dual clutch and slave cylinder. This failure occurred just over one year after Kia replaced the dual clutch and performed a full engine replacement at a Kia dealership. This condition is identical to a known safety recall affecting 2019–2022 Kia Niro vehicles involving hydraulic clutch fluid leaking onto the actuator circuit board and creating a fire risk. Although my VIN is not listed under the recall, the vehicle is the same year, make, model, and drivetrain and is exhibiting the same defect described in the recall. This appears to be a recurring safety defect involving the hydraulic clutch system.

Continuing and worsening motor rumbling noise and ticking/clicking at slow speeds. Spent a couple of months and without car for weeks just to have kia confirm and have gearbox changed. This has existed in some form for a couple years now.

The rear backup camera works intermittent, checked wiring and still having issues, could cause backing issues for people that don't use their mirrors

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.

Car caught fire

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...

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.
