Hi, My Prius Prime recently just suffered the loss of heat in the middle of winter. Based on the diagnostic of my local Toyota dealer, it appears one of the metal heater coolant hose had rusted off. This is not just causing a safety issue of having no issue, it is also a risk as the engine can now overheat and suffer permanent damage. Despite being such a serious problem, Toyota doesn't stock the part nor does it know when the new part will come. I am currently owning an asset that can't be safely driven, I would like the NHTSA to review this. Toyota seems to be aware of this issue as they have a TSB out on a similar heater coolant hose. With that said, having no part is not an acceptable option. NHTSA, please step in

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.
