What stands out
Owners have filed 26 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA electrical complaint has been filed on this vehicle in over 3 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 describe a pattern of serious electrical and engine failures on the 2012 Kia Sportage. Engine seizure is the most common complaint—vehicles stall without warning during highway driving (45–60 mph), with all dashboard warning lights illuminating simultaneously. Several owners report the engine fails to restart after stalling; independent mechanics and dealers diagnose seized engines requiring full replacement, with some dealers quoting $5,000–$8,000 for engine work. A few owners link their failures to NHTSA recall 17V224000 but say their VIN isn't listed despite matching symptoms.
Battery and starter issues compound the problem. Multiple owners report dead batteries paired with alternator or starter failures; one replaced both alternator and battery, then experienced a similar event weeks later. One owner's battery posts were cited as oversized for connectors, causing total electrical failure and loss of power steering and brakes at 16,000 miles.
Accessory electrical failures are widespread: power window switches fail repeatedly—some owners have replaced the same switch three times—and stop responding to passenger controls. Door locks malfunction, seatbelts stick or fail to retract properly, sunroofs won't close, fuel gauges read inaccurately, and tire pressure sensors don't function correctly. Two owners report vehicle fires: one parked vehicle caught fire under the hood; another fully engulfed after a short drive. One owner cites an unfixed HECU fuse recall (23V652) with fire risk. Owners also report engine knocking, ticking sounds, burning smells, and stalling linked to low oil pressure warnings despite regular maintenance.

What owners are reporting 1 most recent
The day I drove the car off the lot after purchasing (roughly 4 years ago) the low tire pressure sensor came on and I was unable to get it to go off. Mentioned it to the dealership whenever I went back for my first oil change and they told me they were able to “wake it up” whenever they checked the tire pressure. It continues to not accurately read if the tire pressure is low or not. A couple of…
