What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 7 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.
SUMMARY TO BE PROVIDED ON A FUTURE DATE.

The failure pattern owners describe
The 2006 Sportage has widespread electrical problems that go far beyond inconvenience. Owners report the engine shutting down without warning during braking, turns, and highway driving—dangerous when traffic or weather demands control. Dealers struggle to diagnose it; one case required a month of data-logging to catch an ECU thermal overload.
The blower motor harness and resistor are a recurring fire hazard. Multiple owners discovered melted connectors, charred wiring, and burning smells. Dealers have disconnected the units entirely rather than fix them, leaving owners without heat or AC. One owner found wiring so damaged that the casing had completely melted away.
Brake lights stay on indefinitely after the engine shuts off in some vehicles, draining the battery. Stop lamp switch failures prevent cruise control and trigger false ESC warnings. Kia knows the stop lamp switch issue is a defect but didn't recall all 2006 model years—owners who missed the cutoff must pay out of pocket. Wiring harnesses become brittle and corroded, causing unintended acceleration or deceleration while driving. One vehicle caught fire while parked. Radio and AC systems cycle on and off randomly, and door locks fail entirely. Technicians often can't reproduce or fix these issues, leaving owners stranded.

Failure modes owners describe
Engine stalling during braking or turns
Engine shuts down completely while braking to enter a lane, turn, or slow down. Occurs at highway speeds and during normal driving. Power loss prevents OBD-II from logging codes in some cases. Restarting the vehicle restarts it normally.
When: 69,245 miles at initial report; occurs sporadically from 60,000 miles onward; one case at highway speed (75 mph)
Symptoms owners cite: engine cuts off while braking; engine shuts off during turns or lane changes; vehicle loses all power including electrical; occurs while decelerating to stop; multiple restarts required; ESC and cruise control affected
Repairs/costs cited: One case: ECU replaced after thermal overload detected via data-logging. Throttle Position Sensor (TPS) replacement suggested at $248, but not confirmed to fix issue. Dealer diagnosis inconclusive in most cases.
Recalls/TSBs owners mention: KIA HQ directed dealers to wiggle wires to reproduce problem; no successful recall identified for engine stalling defect
Blower motor resistor and harness melting/fire hazard
Blower motor connector, resistor, and harness overheat and melt, creating visible burning smell and immediate fire risk. Connectors become brittle, corroded, and charred. Some wiring casing completely melted off. Dealers disconnected units to prevent fire rather than repair.
When: 70,000 to 92,000 miles reported; some cases early in ownership
Symptoms owners cite: AC and heating work sporadically then fail; burning smell from blower area; melted connectors and wiring visible; charred/blackened harness; radio interference and GPS overheating after connector failure; blower motor fan fails
Repairs/costs cited: Blower motor fan replacement; blower motor resistor and harness replacement required. One owner replaced connectors and harness themselves; another paid for dealer repair. Costs not fully detailed except one case: $161 total bill.
Recalls/TSBs owners mention: NHTSA Campaign 15V015000 exists for Electrical System but does not cover all affected VINs. Dealers disconnected units to preserve engine warranty rather than address root cause.
Brake lights staying illuminated after ignition off
Brake lights remain lit when vehicle is parked and ignition is off. Vehicle must be left unplugged or lights cycled repeatedly to turn off. Persists for over a year in some cases.
When: 240,000 miles in one report; ongoing for over a year in another
Symptoms owners cite: brake lights stay on indefinitely; lights remain illuminated when parked and key off; lights won't turn off without repeated cycling; battery drain concern
Repairs/costs cited: One owner had to disconnect battery to turn off lights. No repair attempted by dealer.
Recalls/TSBs owners mention: Related to NHTSA Campaign 09V130000 (Exterior Lighting) but affected VINs were excluded from recall
Stop lamp switch failure affecting cruise control and ESC
Stop lamp switch fails, causing ESC warning light to illuminate intermittently and cruise control to malfunction. Cruise control stops working entirely; ESC light cycles on and off. Issue is known but not recalled for all 2006 model year vehicles.
When: Began intermittently around 60,000 miles; became full problem around 92,000 miles
Symptoms owners cite: ESC warning light on and off repeatedly; cruise control disengages on its own; cruise control won't set or engage; intermittent issues escalate over time
Repairs/costs cited: Stop lamp switch replacement required. One owner paid $100 warranty deductible; total bill $161. Dealers confirmed defect is known for 2006 Sportage.
Recalls/TSBs owners mention: NHTSA recall exists for stop lamp switch but 2006 Sportages were excluded based on VIN date cutoff. KIA consumer line stated 'too bad' when contacted.
Wiring harness failure and electrical control harness malfunction
Electrical control harness becomes cracked, brittle, and corroded. Causes sudden deceleration while driving and unintended acceleration/deceleration. Also causes HVAC system (heater, defrost, AC) to fail. Fuse block replacement required in some cases.
When: 137,723 miles; 72,000 miles in another case; various mileages throughout ownership
Symptoms owners cite: vehicle decelerates unexpectedly while driving; vehicle accelerates and decelerates on its own; loss of heating and defrosting capability; AC and heating lose function; check engine light illuminates; harness visibly melted or corroded
Codes mentioned: Check engine light illuminated in at least one case
Repairs/costs cited: Electric control harness replacement needed. Fuse block replacement required in one case. One owner refused repair due to cost. Factory rep rewired harness by replacing melted wiring in one case.
Recalls/TSBs owners mention: No recall identified. Dealer diagnosis confirmed need for harness replacement but no manufacturer-initiated fix
Door lock failure
Driver-side door lock fails electrically, preventing door from opening normally. Owner must climb over seats to exit vehicle.
When: Within a few weeks of ownership
Symptoms owners cite: door will not open from inside; door lock inoperable
Repairs/costs cited: Not repaired in complaint narrative
Vehicle fire from faulty wiring
Vehicle caught fire while parked. Inspection revealed faulty wiring as cause. Fire occurred with vehicle stationary for approximately 45 minutes.
When: 13,000 miles
Symptoms owners cite: vehicle caught fire while parked; no warning signs reported
Repairs/costs cited: Vehicle towed to shop; repair not completed as of complaint date
Recalls/TSBs owners mention: Manufacturer stated they would send inspector to examine vehicle
Radio and AC turning on and off intermittently
Radio and AC systems cycle on and off spontaneously for no apparent reason. Occurs while driving and at rest.
When: Various mileages
Symptoms owners cite: radio shuts off and comes back on by itself; AC cycles on and off randomly; radio changes stations on its own
Repairs/costs cited: In one case related to melted blower motor connector; once connector replaced, all electrical interference stopped
Airbag warning light and airbag non-deployment
Airbag warning light remains illuminated. Related to Takata recall. Airbags reported not to deploy in accidents.
When: Vehicle purchased in 2018; issue present at purchase
Symptoms owners cite: airbag warning light on; airbags do not deploy in accidents
Repairs/costs cited: Dealer scheduled inspection
Recalls/TSBs owners mention: Takata recall cited; dealer initially dismissed airbag light as non-critical

Brake lights stay on after turning off the ignition and shutting off the lights. Have to turn lights on off depress the brake pedal, turn on and off the lights and keep doing it until they go off.. Has been happening for over a year. Read online that there's a history of this but no recall.
This car continues to have problems with speeding up and slowing down on its own, at this point it shut off any time I was slowing down for a light or stop. It cut off multiple times on a highway going 75 MPH. Very scary with kids in car. Was able to get home and it will not turn over or start back up getting diagnosed today, there needs to be something done about this issue, I have read 100s of…
I had Kia inspect the air conditioner because it started working sporadically. I was informed by Kia that they disconnected the unit to prevent the car from catching on fire. Verbatim: found blower motor bad and fried resistor and harness. Left unplugged to prevent fire from starting. This vehicle is well maintained and certainly should not have any air issues unless freon is needed. This…
