“While traveling from upstate New York, the vehicle displayed an engine overheating warning shortly after startup while the engine was still cold. Because I was away from home, I stayed overnight and the next morning took the vehicle to a Kia dealership for inspection. The dealership inspected the vehicle and diagnosed a problem with the exhaust heat recovery system pipe. According to the service department, coolant is leaking internally through this component and is being burned in the exhaust system. …”

“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!!”

“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. …”
