NHTSA Complaint #11521907 — 2017 HYUNDAI ELANTRA

Ignition Coil Failure on 2017 Hyundai Elantra with just over 29,000 miles. Engine misfiring, jerking, idling roughly, and hesitating while accelerating, along with the Check Engine Light turning on. On-board diagnostic tool generated a P0-301 Diagnostic Trouble Code - indicating that cylinder number 1 experiencing misfires. Took my car to dealer for repair. Ignition coil and software updated pursuant to Hyundai TSB # 20-FL-001H. Cost $321.46. Hyundai would not pay for all/part of the repair because car is beyond the 5 year/60,000 mile warranty, despite this being a safety issue they acknowledged by issuing the TSB to address the replacement of the defective ignition coils. Hyundai previously issued safety recall on 2106 Sonata models related to a similar defective ignition coil issue. See Hyundai TSB # 16-01-003-1. Ignition coils are expected to last at least 100,000 miles. The premature failure of this part, as evidenced by the 2016 recall, and the 2020 TSB, poses an unreasonable safety risk to the public. Imagine the safety issues while traveling on a roadway with your car misfiring, jerking, or lacking power when accelerating, or stalling.
