Software upgrades for Hyundai, Kia vehicles cut theft rates by more than half

The software fix for highly stolen Hyundai and Kia vehicles seems to be working, according to the Highway Loss Data Institute.

Some Hyundai and Kia models have been targeted by thieves who appear to be exploiting their lack of anti-theft immobilizers – a device that prevents the engine from starting if the matching, properly coded key fob isn't detected.

Immobilizers were standard on 96% of other manufacturers’ vehicles sold in the U.S. by 2015, but Hyundai and Kia, both from Hyundai Motor Group, didn’t make them standard until about six years later.

Thieves took note of the comparative ease in stealing the cars without the immobilizers, with word spreading on TikTok and other social media channels.

HLDI said in 2022 that theft claims were nearly twice as common for 2015-19 Hyundai and Kia vehicles compared to all other makers for those model years.

The automakers began offering anti-theft software upgrades for affected vehicles in early 2023. Roughly two dozen 2011-22 Hyundai and Kia models are eligible for the upgrade, HLDI said.

The vehicles that received the upgrade as of last December had theft claim frequencies that were 53% lower than vehicles that didn’t get the upgrade, new research from HLDI found.

“The companies’ solution is extremely effective,” Matt Moore, senior vice president of HLDI, said in a news release last week. “If you own a Hyundai or Kia vehicle without an electronic immobilizer, you should call your local dealer about getting the software upgrade today.”

As of mid-July, about 60% of eligible vehicles had been upgraded, HLDI said.

Cars with the software upgrades will only start if the owner’s key or an identical duplicate is in the ignition. The upgraded cars also get a window sticker aimed at deterring potential thieves.

HLDI said claim frequency for both theft and vandalism continued to rise for Hyundai and Kia throughout 2023 despite the implementation of the software upgrade, though the rate of increase for theft tailed off dramatically.
