preliminary evaluation is often closed with no action; an engineering
analysis is the stage that usually precedes a recall.

the electrical system
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.

ENGINE
The vehicle has suffered a catastrophic failure of the hybrid drive motor rotor, transmission, and engine clutch, resulting in a $14,993 repair quote. This is a direct consequence of a failed remedy for NHTSA Recall 18V260 (Hyundai Campaign 176).In February 2020, a dealer performed an 'inspection/cap' remedy under Campaign 176. However, this did not permanently fix the manufacturing burrs on the hydraulic clutch actuator housing. Over time, the inner oil seals degraded exactly as warned in the original defect report. Hydraulic fluid leaked into the electric stepper motor, causing an electrical short circuit that destroyed the entire hybrid powertrain. The vehicle lost propulsion and threw a …
