Consumer Description
NHTSA should have a non-official recall warning for Hyundai vehicles that have this software based Safety Defect, which is some models don't have a Passive Engine Immobilizer, and the vehicles can be easily stolen by starting the engine with a USB cord. Thankfully Hyundai(recall) offered a free Anti Theft Software Update, and a steering wheel lock. I checked my VIN number with the Hyundai Dealership in Oregon, and they said my car already received the Anti Theft Software Update. The only reason I knew my 2020 Tucson had this issue, is because State Farm cancelled my insurance a month after I started paying for it. State Farm and Progressive currently deny new policies for vehicles without a Passive Engine Immobilizer. Also State Farm still denied my insurance after I got the software update. Affected Hyundai models from 2011 to 2021 that have standard “turn-key-to-start” ignition systems/without a Passive Engine Immobilizer, are the Accent, Elantra, Santa Fe, Sonata, Tucson, Genesis Coupe, Palisade, Kona, Venue.
