Four-pin tow-hitch harness short and fire risk
Certain genuine Kia four-pin tow-hitch harnesses can short after moisture or debris contamination and create a fire risk.
What the reviewed source says
Start with the documented condition, not a parts guess.
Kia recall SC247 applies to certain 2020 to 2022 Telluride vehicles fitted with a genuine Kia four-pin tow-hitch harness. Contamination on the harness module circuit board can cause a short and a fire while driving or parked with the ignition off. The genuine Kia seven-pin harness and aftermarket harnesses are not included in the dealer repair bulletin.

What the official procedure directs
Kia tells dealers to inspect the genuine four-pin harness and repair or replace it as required. The updated 15-amp fuse is installed when it is not already present.
Recall 22V-626 depends on vehicle production and genuine four-pin harness fitment, not mileage.

Repair paths and safe checks
Separate the diagnosis from the action.
Complete Kia recall SC247
Have Kia identify the harness and VIN. The dealer repairs or replaces an affected four-pin harness, then adds the protective extension. The lower-rated fuse is installed when required.
A fuse-only repair may not be the complete current remedy for a vehicle that still has an open SC247 campaign.

Check whether the connector is four-pin
From outside the vehicle, note whether the trailer connector has a flat four-pin layout and photograph it for the dealer. Do not remove covers, fuses or wiring.
Move away and call for help if the rear harness is hot, smoking or smells burnt.

Read the method beside the problem
These guides explain the safety and evidence checks that apply to this problem file.
Check recalls by VIN
A VIN search checks the displayed NHTSA records for an unrepaired safety recall associated with one vehicle. A model search shows only the wider campaign population.
Read guide ↗When a car is unsafe
A warning light does not always mean the same thing, but weak brakes or smoke leave little room for experimentation. Damaged tires and certain recall instructions can do the same.
Read guide ↗Why symptoms overlap
“It makes a weird noise” is useful human language. Diagnosis begins when that language is tied to the exact vehicle and its operating conditions.
