Ford Fusion energi battery failure. Dealership wouldn't inspect the battery and kept replacing the battery control module. The replacement part kept failing under warranty and then the dealership quoted me $20,000 for the hybrid battery. They have replaced the BCM twice and error code P0dc9 keeps appearing. The EV range drops to zero randomly or gains range while parked and not plugged in. Dealership doesn't know what's happening even after paying money for diagnostics.

I routinely have plugged in my PHEV, enjoying the quiet electric ride. I could complete a day's commute with the electric charge. However, the battery capacity was significantly reduced at about 50K miles. At about 73K miles, within a couple miles of starting to drive, the car would decelerate and go into 'limp mode', with a top speed of 35MPH. A warning signal of a wrench would appear, indicating a power train fault. While diagnostics at the dealer didn't detect a cause, an emissions test required by the State of Colorado found an 'unstable Hybrid Battery A voltage'. I replaced the spark plugs as recommended by the dealer, but that didn't address the problem. The diagnostics and repair cost about $1000.00

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.
