Shift to park issue. When stopping the car and placing it in park it will flash a warning message stating that you need to "Shift to Park" even though the car is in park. As a result the car will effectively keep running for a period of time. My 2017 Volt began exhibiting this issue recently. I took it to the local Chevy dealer who charged me $106.00 to tell me what they already knew since there are multiple Service Bulletins for this issue. The car only has 34k miles on it but is past the 3 year limit so they also want to charge me to repair it but based on multiple online chatter the repair does not typically last for more than a year. Why is something like my car will not shut off not being treated as a safety concern??

IT IS AN ONGOING ISSUE AND THAT HAPPENS INTERMITTENTLY. WHEN ARRIVING TO A STOP (AT TIMES) THE CAR STILL ADVANCES FORWARD ABOUT A FOOT, EVEN WHEN THE BRAKE PEDAL IS BEING USED AS FAR AS IT CAN. ALSO THE VEHICLE CLAIMS TO BE LOSING PROPULSION, OFTEN, AND SEEMS STRAINED WHEN OPERATING WHEN THE MESSAGE APPEARS.

MY 2017 CHEVROLET VOLT PRESENTS A "SHIFT TO PARK" ERROR. WHEN I SHIFT THE TRANSMISSION TO PARK AND PUSH THE START/STOP BUTTON, I RECEIVE AN ERROR MESSAGE ON THE DASH DISPLAY INDICATING: "ACTION REQUIRED: SHIFT TO PARK." THE TRANSMISSION SHIFTER REMAINS LOCKED IN THE PARK POSITION. THE PROBLEM IS ONLY CURRENTLY RESOLVED BY PRESSING THE BRAKE PEDAL AND RESTARTING THE VEHICLE, FOLLOWED BY SHUTTING IT BACK OFF AGAIN. I HAVE HAD TO DO THIS UP TO 6 TIMES BEFORE THE VEHICLE WOULD ACTUALLY SHUT OFF. SOMETIMES RESTARTING THE VEHICLE AND SHIFTING IT INTO GEAR, FOLLOWED BY RETURNING IT TO PARK AND SHUTTING IT OFF, RESOLVES THE ISSUE. WHEN THE "SHIFT TO PARK" ISSUE OCCURS, I AM NOT ABLE TO LOCK MY VEHICLE AS IT IS STILL "RUNNING."

2PE23022 · Loss Of Motive Power Due To The Battery Energy Control Module
Opened Nov 29, 2023 · Closed Mar 3, 2025
Status: closed (inferred from source dates) · Electrical System; Electrical System:propulsion System; Electrical System:propulsion System:traction Battery:management System/energy Control Module (bms/becm)
On November 29, 2023, the Office of Defects Investigations (ODI) opened PE23022 to investigate allegations of a loss of motive power, including a stall, reduced power state, and/or a no start condition due to the Battery Energy Control Module (BECM) in model year (MY) 2016-2019 Chevrolet Volt passenger car vehicles manufactured by General Motors (GM). The BECM is located within the high voltage electric vehicle (EV) battery pack and monitors the temperature, current, and voltage of the high voltage battery cell groups. GM stated that the root cause was identified as an internal failure leading to a loss of communication within the BECM and does not pose a risk to motor vehicle safety. GM further stated that the failure cannot result in a complete stall, only a reduced power mode, no start condition, or a no charge condition. GM additionally stated that if these conditions occur, the driver will be warned via a Malfunction Indicator Lamp (MIL) and/or a reduced-propulsion message in the Driver Information Center (DIC). Data received and analyzed by ODI from all sources indicates that nearly all related BECM failures caused conditions aligning with GM’s predicted outcomes. Despite the large number of warranty claims, nearly all failures were not safety-related, i.e., not a stall or reduced power mode. ODI isaware of a single minor crash and no injuries or deaths. In March 2024, GM issued Special Coverage N232432680, which was mailed to consumers, addressing BECM failures in certain MY 2016-2018 Chevrolet Volt vehicles. This special coverage provides an extension of the warranty coverage for the BECM from 8 years / 100,000 miles to 15 years / 150,000 miles for all 2016-2018 Chevrolet Volts. Additionally, GM stated that replacement components are sourced from a different supplier and not susceptible to the failure. In view of the Special Coverage issued by GM, the existing warranty coverage already in place, and the low number of safety-related occurrences, ODI is closing this Preliminary Evaluation (PE). The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

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.
