Why does my 2009 Kia Sorento Intermittently go into limp home mode?
Asked by Brian
Intermittently, when I start the engine of my 2009 Kia Sorento, it's in limp home mode. I pull up, turn off the engine and restart and sometimes it can be fine. What should I do?

4 Sep 2021Before you do anything, take the car to a workshop with the correct diagnostic gear and have it scanned. This process will see the workshop’s computer have a deep and meaningful conversation with the computer in your car, and the result will probably be a fault code(s) that will tell the mechanic exactly what’s going wrong.
Beyond that, you’re merely stabbing in the dark, as limp-home mode can be triggered for all sorts of reasons including dud sensors, poor wiring, a computer glitch, you name it. The fact that it’s an intermittent limp-home situation makes it even harder to diagnose without a computer scan. You cans start to replace components at random to see if they fix the problem, but you’ll probably wind up replacing a whole heap of perfectly working ones before you stumble on to the one that’s playing up. In the meantime, you’ll have spent heaps and wasted weeks.
