What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners of 2007 Sorentos report a constellation of electrical failures that create real safety hazards. The most alarming are fires: multiple owners describe electrical fires originating in braking circuits, wiring harnesses, and dash areas—some while the vehicle was parked with the engine off. One fire ignited in the trailer hitch wiring harness despite the vehicle not towing anything. Brake light switches fail repeatedly; one owner replaced the same component three times after a factory recall, then Kia refused to cover additional failures. Another owner found themselves ineligible for a brake light recall despite having identical symptoms.
Engine and power-delivery failures are common: the ESC light comes on and forces the vehicle into limp mode, capping speed at 20 mph for extended periods. This creates dangerous merge situations on highways. Some owners report a transfer case decoder motor failure costing $1,000 to repair. An alternator that failed eight times in eight months suggests deeper electrical stress.
Interior lighting quits working—dome lights, front door lights, rear hatch lights all refuse to activate when doors open, though manual switches work fine. One repair shop found hundreds of posts from 2003-onward Sorentos with the same problem. Headlights dim while driving. Speedometer readings lag behind actual speed. Airbag warnings light up permanently and passenger occupancy sensors show "off" even with someone in the seat. Rear wipers run continuously, even with the engine off. These are not fringe complaints; owners describe researching online and finding the same problems across generations of this model.

Failure modes owners describe
Transfer Case Decoder Motor Failure
Transfer case decoder motor fails, causing loss of power, inability to shift out of gear, and illumination of Check Engine and ESC OFF lights simultaneously. One owner reports the component requires service around 45,000 miles per internet research, though no dealership mentioned this during prior visits.
When: One report at unspecified mileage
Symptoms owners cite: Check Engine light illuminates; ESC OFF light illuminates; Vehicle loses power; Cannot shift out of 2nd gear; No throttle response
Repairs/costs cited: Transfer case decoder motor replacement cost approximately $1,000 total including diagnostics; part itself $570
ESC and Power Loss with Limp Mode Activation
Vehicle enters limp mode (safe mode) when accelerating, with ESC light illuminating and engine unable to exceed 20 mph for extended periods. Multiple owners report this as a widespread issue affecting 2007 Sorentos. Creates hazardous traffic situations where vehicle cannot merge or accelerate safely.
When: Occurring during acceleration on highways and surface roads
Symptoms owners cite: ESC light illuminates during acceleration; Vehicle enters limp mode restricting speed to 20 mph or below; Engine hesitates or loses power on acceleration; Condition persists for long periods
Repairs/costs cited: Owners report high dealership costs deter repair attempts; specific repair costs not stated
Electrical Fire—Braking Circuit and Wiring
Multiple reports of electrical fires originating from braking circuits, wiring harnesses, and dash areas. Fires occur both while vehicle is running and while parked with engine off. One report specifically identifies trailer hitch wiring harness short circuit. Owners report receiving manufacturer recall warnings about fire risk but dealerships initially unaware of recalls.
When: 102,000 miles (one report); one at idle; one while parked with cold engine
Symptoms owners cite: Smoke from engine compartment and under dash; Brake lights remaining on with engine off; Visible fire under rear of vehicle; Smoke from hood while vehicle at idle; Vehicle fire in rear tail light area while parked

Recalls/TSBs owners mention: Manufacturer issued recall notices (NHTSA 20V088000 for electrical system, service brakes, hydraulic); manufacturer stated in one case fire was not associated with recall
Brake Light Switch Failure—Brake Lights Inoperative
Brake lights fail to illuminate when brake pedal is pressed. One owner reports this is a recalled component that has failed three times already; Kia refused to cover repeat failure costs. Another owner was deemed ineligible for the brake light recall despite having identical symptoms to the recall issue. Creates safety hazard of rear-end collision risk.
When: One owner had three failures in unspecified timeframe
Symptoms owners cite: Brake lights do not illuminate when brake pedal pressed; Check Engine light may illuminate; ESC OFF light may illuminate
Codes mentioned: NHTSA Campaign 13V114000 (KIA Service Campaign SC098)
Repairs/costs cited: Brake light switch replaced three times in one case; Kia refused warranty coverage on repeat failures
Recalls/TSBs owners mention: NHTSA Campaign 13V114000/KIA Service Campaign SC098 issued for this component; some owners deemed ineligible despite matching VIN and symptoms
Alternator Repeated Failure
Alternator fails repeatedly, requiring replacement eight times between April 2016 and December 2016. Vehicle stalls and warning lights illuminate with each failure. Independent mechanic confirmed diagnosis on multiple replacements.
When: Starting April 2016 at approximately 100,000 miles
Symptoms owners cite: Vehicle stalls while driving; Multiple warning indicators illuminate on instrument panel
Repairs/costs cited: Alternator replaced eight times total within approximately eight months; no specific costs cited
Door-Activated Interior Lights Inoperative
Dome, front, and rear hatch lights fail to activate when doors open, though lights work when manually switched on. Repair shop confirmed it is not a switch issue and identified it as electrical system problem. Found evidence of hundreds of posts from 2003+ Sorentos with identical issue.
When: Progressive failure starting with dome light

No diagnostic trouble codes generated. Owner suspects electrical issue. Condition has worsened over two years of ownership.
When: Progressive worsening over two years of ownership; occurs above 30 mph

When opening doors, the dome light no longer would turn on. This eventually continued until the front lights no longer turn on, and now the rear hatch lights do not turn on either. The lights work when they are manually turned on, just not when the doors open. It was checked by a repair shop and they say it is not a switch issue (as the lights on three of the doors still light when open).…
I own a 2007 Kia sorento. Recently, my check engine and ESC off lights became illuminated on my dashboard. I noticed that my brake lights were not illuminating when I pressed the brake pedal. After looking up my car make and model on the NHTSA website, I noticed there was a recall for my model year sorento for the exact same problems (NHTSA campaign number 13v114000/Kia service campaign sc098). I…
