The Hyundai Ioniq was designed with a dual clutch system for the electric motor and gas motor. This was done to disengage and engage either separately when necessary for low power, regen braking, etc. However, this design heavily impacts the behavior of the brakes and safety of the vehicle overall. When the brakes are applied, the ECU will turn off the gas engine to conserve gas in regen braking mode. Additionally, the ECU will downshift the transmission. Downshifting the transmission and disengaging the gas engine become an issue because conducting both actions removes significant resistance in braking. Causing the vehicle to lurch when the downshift occurs while also increasing stopping distance. This downshift can be felt when braking as both loss of brake power and vehicle lurch. The system also does not account for this brake power loss by increasing brake booster response.

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.
