2018 Hyundai Ioniq Plug-In Hybrid

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

I am writing to dispute the denial of my paint defect warranty claim formally and to demand that Hyundai Motor America reconsider its decision. My 2018 Hyundai Ioniq (Silver, VIN: [XXX] ) is exhibiting significant paint bubbling — the identical defect that Hyundai has already acknowledged and accepted responsibility for in white-painted vehicles across multiple model years. Timeline of Events • I first contacted Hyundai Customer Care by phone, and was directed to visit an authorized dealership. • On May 8, 2025, I visited Tustin Hyundai, where Dealer Coordinator Alex Cervantes documented the paint bubbling by photographing the affected areas and submitted the claim to Hyundai Motor America on my behalf. Dealer Reference #: XXX. • On May 11, 2025, Alex called and mentioned that Hyundai has denied my claim. Basis of My Complaint Hyundai has publicly acknowledged that paint bubbling and delamination affecting certain 2017–2018 model-year vehicles constitute a manufacturing defect, not owner negligence or environmental damage. In response, Hyundai issued Warranty Extension TXXW and subsequently the broader Z05 extension (10 years/unlimited miles), covering affected vehicles with white paint. The paint defect on my silver 2018 Ioniq is identical in nature and presentation to the defect that Hyundai has already accepted responsibility for. The bubbling is occurring on body panels — not due to collision damage, improper maintenance, or environmental factors — and is consistent with the delamination pattern described in Hyundai's own Technical Service Bulletins. Denying my claim solely based on paint color, while acknowledging the same underlying manufacturing defect in other colors, is inconsistent and Hyundai not accepting responsibilty.

I have put around 31K miles in my car. Day before yesterday ( Nov-2 ) when I was driving back home from work, suddenly I heard a noise. I pulled over and stopped the car. when I got down and checked, I noticed exhaust system or something similar to that fell off and touching the road. I have seen similar issues posted in Hyundai Ioniq forums https://www.ioniqforum.com/threads/very-dissapointed.37027/ https://www.ioniqforum.com/threads/first-issue-exhaust-fell-off-at-21k-miles-2019-phev.35092/ I will attach few pictures that I took during this incident.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.

Some vehicles may exhibit a loss of connectivity or interruptions in the middle of using Bluelink Service functions. This may be due to an irregular disconnection on Verizon’s communication network. Follow the procedure in this TSB to reestablish the connection via the AVN pinhole reset method.

This bulletin contains information about the proper removal of the windshield wiper blade protective cover on all models. If the protective cover is not removed correctly, there is a possibility of the rubber insert and rail spring becoming partially separated on the inner side of the wiper blade, which could lead to poor wiping performance and/or possible scratching of the windshield glass. Follow the procedure in this bulletin to properly remove the windshield wiper blade protective cover on all new wiper blades.
