ON VARIOUS OCCASIONS, THE CAR SIGNALS "SHIFT TO PARK" WHEN IT IS IN PARK. THIS WILL NOT ALLOW ME TO LOCK THE CAR OR LEAVE MY CAR. THIS SEEMS UNSAFE TO ME. ON ONE OCCASION IT WOULD NOT ALLOW ME TO EVEN TURN OFF MY CAR. THE TIME IT TAKES FOR THE SIGNAL TO GO AWAY HAS VARIED, BUT IT ALWAYS ENTAILS HAVING TO CHANGE GEARS OR DRIVE FORWARD AND BACKWARD A LITTLE BIT. THIS HAS OCCURRED IN IDLE POSITION, AT HOME, ON STREETS, IN MALL PARKING LOTS, MANY VARIOUS LOCATIONS. *TR

WHEN I WOULD PUT MY CAR IN PARK, THE CAR WOULD NOT TURN OFF. IT WOULDN'T HAPPEN ALL THE TIME AND I THOUGHT I WASN'T PUTTING MY FOOT ON THE BRAKE, OR I THOUGHT MAYBE I DID SOMETHING ELSE WRONG. IT WAS FRUSTRATING AS I THOUGHT I WAS GOING CRAZY. THEN ONE DAY 'I WAS SO FRUSTRATED , I SLAMMED THE GEAR SHIFT INTO PARK AND IT ACTUALLY TURNED OFF. THAT WAS AN 'AH HA' MOMENT. SHORTLY AFTER THAT I MADE AN APPOINTMENT TO GET MY CAR CHECKED FOR THE PROBLEM. THAT'S WHEN I GOT UPSET'THE GUY SAYS 'OH,IT HAPPENS ALL THE TIME TO THIS MODEL'. SO THEN MY HUSBAND SAYS'SHOULDN'T YOU PAY FOR IT IF IT'S A KNOWN DEFECT. THE SERVICE ENGINEER SAYS IT'S NOT STILL ON WARRANTY AND IS NOT A RECALL. SO WE PAID THE $500.00 TO GET IT FIXED. BUT THIS SHOULD BE A RECALL- IT'S A SAFETY ISSUE NOW THAT I KNOW THE CAR WAS NOT TURNED OFF MANY TIMES'SOMETIMES I ONLY KNEW IT WASN'T OFF BECAUSE MY RADIO WOULD PLAY WHEN I LOCKED THE DOOR'AND THE DOOR WOULDN'T LOCK. THIS SUCH A SAFETY ISSUE ON THE HIGHEST LEVEL..I PAID THE MONEY BUT TRULY IT SHOULD HAVE BEEN FIXED BY GM BECAUSE OF THE SAFETY ISSUE. SO THEN THE SERVICE GUY SAYS TO CALL GM, EVEN GAVE US THE NUMBER WHICH TURNED OUT TO BE GENERAL MOTORS BUT YOU NEEDED A CUSTOMER CODE SO THAT DID NO GOOD (855-462-2737). SO NOW I'M ASKING YOU GUYS TO LOOK INTO SOMETHING THE SERVICE DEPT AT DELILLO CHEVROLET SAYS 'WE SEE THIS A LOT'. THE PROBLEM WOULD HAPPEN WHEN I THOUGHT THE CAR WAS IN PARK'IT LOOKED LIKE IT WAS IN PARK BUT IT WASN'T. THEY CALLED IT: SWITCH IN SHIFTER CONTACTS NOT SENDING SIGNAL TO BODY CONTROL MODULE. SO THAT'S MY STORY, AS FRUSTRATING AS IT WAS. MY CAR NOW SHUTS OFF ON A REGULAR BASIS. I JUST FEEL SORRY FOR THE NEXT PERSON WHO CAN'T SHUT OFF THEIR CAR!!! *TR

REPEATED SHIFTING OUT OF PARK AND BACK EVENTUALLY AFTER MULTIPLE TIMES ALLOWS FOR CAR TO TURN OFF. STARTED ONLY OCCASIONALLY TO HAPPEN ABOUT 1 YEAR AGO AND NOW HAPPENS MULTIPLE TIMES PER WEEK. THIS SEEMS TO BE A COMMON EVENT FOR VOLT 2017 AND EARLIER AND OTHER CHEVY MODELS AND NEEDS A RECALL. I HAD TO LEAVE CAR RUNNING ON TWO OCCASIONS.

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.
