Kia Soul Overheating: What Owners Report
203 of the 5,538 owner complaints NHTSA has for 2008–2024 Soul models describe overheating. Here is which years and systems show up most, what owners say, what to check first, and when a mobile mechanic can fix it where the car sits.
NHTSA data pulled September 2026.
Pull over when it is safe, turn the engine off and let it cool. Never open the radiator or coolant cap on a hot engine – the coolant is under pressure and can burn you.
Which Soul years report it most
Reports peak with the 2016 model year (47). A year with more cars on the road usually has more reports, so use this to know what to ask, not to rank years.
What else these reports mention
Owners filing these complaints most often also named the engine and engine and cooling – usually where a mechanic starts looking.
| System named | Reports | Mobile mechanic? |
|---|---|---|
| Engine | 153 | Diagnose first |
| Engine and cooling | 30 | Diagnose first |
| Electrical system | 19 | Often in the driveway |
| Fuel system | 19 | Diagnose first |
| Transmission and drivetrain | 17 | Usually a shop |
| Exterior lights | 9 | Usually on the spot |
What Soul owners describe
“The melting of this connector caused the engine to start over heating and the a/c to no longer cool.”
“Wiring harness seems to be overheating causing lamps to keep blowing.”
“I checked all of my fluids, they were fine and my car wasn’t over heated.”

Safety recall repairs are done free by the brand's dealers. A mobile mechanic cannot do recall work. Enter your 17-character VIN at nhtsa.gov/recalls to see open recalls on your exact car. "Park it" means NHTSA and the maker say not to drive the vehicle until it is fixed.
What to check first
- Once the engine is cold, check the coolant level in the overflow tank.
- Look under the car for green, orange or pink puddles – a coolant leak.
- Check whether the radiator fan runs when the engine is warm and the A/C is on.
- Watch for white smoke from the exhaust or a sweet smell, which can mean a head gasket problem.

Can a mobile mechanic fix it?
Often. Thermostats, hoses, radiators, fans, water pumps on many engines and coolant leaks are common mobile jobs. A blown head gasket or a cracked engine block needs a shop.

|---|---|---|---|
| Thermostat | $616–716 | Quoted after a look | Too few published mobile prices to show a range |
| Water pump | $891–1,135 | Quoted after a look | Too few published mobile prices to show a range |
| Radiator | $1,368–1,550 | Quoted after a look | Too few published mobile prices to show a range |
