Engine 134 1 crash 10 fire

“My KIA Soul 2018 caught on file while driving. The whole engine was in flames. I didn't want to die because my car has a manufacturing issue that KIA was not aware about. The dealership I've purchased the car from denied to give me a copy of the mechanical inspection done at the dealership Stonebriar Chevrolet in Frisco, TX. The flames started under the car and made its way to the engine, smoke was coming from the AC vents. People were able to put the fire down before it got to the gas tank. Due to the seriousness of the damage, the car stopped working and we left it on the side of the road.”

Power Train 31

“On [XXX], my 2018 Kia Soul (VIN [XXX] ) displayed DTC P1326 with a blinking check engine light and went into limp mode.

How we read this (methodology)

How to read this: raw complaint totals are not a clean reliability score — a model year with more cars sold, or simply more years on the road, accumulates more complaints regardless of how good it is. So this page leans on two signals that are not distorted by sales volume: the share of complaints falling on each vehicle system (the breakdown above) and NHTSA's own crash / fire / injury / death flags. When we compare model years of the same model, we normalise by years on the road (complaints ÷ vehicle age) rather than comparing raw totals. Age-normalised, the 2018 Kia Soul draws about 23.6 complaints per year on the road, ranking 9 of 15 among the Kia Soul model years we have ingested (1 = most complaints per year on road).

Before you buy this Kia Soul

Don't buy on the strength of a problems page alone. Check the exact VIN of the car you're looking at. The open recalls are free, and the full $19 safety report pulls every complaint, safety rating and a downloadable PDF for that one vehicle.
