I had my first major breakdown on my 2014 Cadenza this past weekend. I was out shopping, pulled out of a parking lot onto the street and when I gave the car gas, it failed to respond. It was like it was being limited to no more than 1,500 RPM. Shut the car off to see if that might reset it, but when I tried to start it again, the engine cranked for about 5 seconds before it started, and I still had the non-responsive throttle. A warning on the infotainment screen popped up that it was running a diagnostic, and that an Engine Control Unit Fault was detected. Kia roadside assistance towed it to my local dealership. The tow truck driver said it sounded like some sort of engine fault put the transmission into a safety mode that limits the engine RPM? The dealership diagnosed it as a failure of the high pressure fuel pump. I'm still covered under the 5 year, 60,000 mile warranty (second owner), so it was all covered. On the paperwork, it said that it would have been nearly $800, most of that was parts. Labor must have been only an hour or two, since they got my car in to the garage after lunch and had it done around 4.
Just a heads up in case anyone else experiences this.
