The vehicle exhibits a dangerous electrical defect involving uncontrolled power-cycling. After shutting down the car, it automatically restarts itself in a continuous loop. During these episodes, the dashboard flickers, the drivetrain shudders, and the vehicle becomes unresponsive to manual 'Stop' button or brake inputs. Most critically, the car autostarts while parked in an enclosed garage. As a Plug-in Hybrid (PHEV), once the EV battery depletes, the internal combustion engine (ICE) engages automatically. This creates a life-threatening risk of Carbon Monoxide (CO) poisoning for residents in the connected home. A Honda dealership has professionally diagnosed the cause as a failure of the Body Control Module (BCM). This module failure also causes the anti-theft alarm to trigger uncontrollably and renders the keyless entry system inoperable. This defect turned the vehicle into a life-safety hazard in a residential setting. Visual documentation of the uncontrolled power-cycling and dashboard flickering can be viewed at: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine revs very high and the car dramatically slows down. This has happened three times (including today) in the two years I have owned the car. Once was extremely dangerous as it happened on an Interstate highway when traffic was at highway speeds. We were able to avoid getting in an accident though. Why is there no recall for this common problem with this car?

While driving home at night I exited the 60 Freeway and turned right to go up a hill. The car would not move forward and I had to pull over. I noticed the battery indicator had 1 bar on it and the engine revved but the car would not go. After waiting the battery got recharged and we were able to complete our trip. I believe we w…

While driving home at night I exited the 60 Freeway and turned right to go up a hill. The car would not move forward and I had to pull over. I noticed the battery indicator had 1 bar on it and the engine revved but the car would not go. After waiting the battery got recharged and we were able to complete our trip. I believe we were at risk due to the car slowing so suddenly it could have resulted in being rear ended. The car has not been taken yet to a dealer for this issue or been inspected by anyone. There were no warning lights or sounds from the car. This is second time this has happened in similar circumstances.

Status: closed (inferred from source dates) · Electrical System:propulsion 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.
