LIKE OTHERS, INCLUDING THE INCIDENT IN RANCHO CUCOMONGA, CA ON THE SAME DAY, APRIL 25TH, I WAS DRIVING ON THE HIGHWAY AT HIGH SPEED. I WAS IN THE CARPOOL LANE ON THE 210 FREEWAY. I THINK I ALSO WAS TOLD TO PUT THE CAR IN PARK. I LOST THE ABILITY TO ACCELERATE ON AT A VERY DANGEROUS TIME, WHILE I WAS THE FURTHEST TO THE LEFT IN THE LATE AFTERNOON. MIRACULOUSLY, THERE WAS ONLY 1 CAR QUITE FAR BEHIND ME. SO, AFTER DECELERATION WAS FORCED UPON MY CAR, I BEGAN TO STEER THE CAR TO THE RIGHT THROUGH 5 LANES - ONE OF THE WIDEST PARTS OF THE HIGHWAY AT THAT POINT. HERE IS WHAT I NOW THINK. I HAVE BEEN THROUGH LOSS OF POWER IN MY 2014 VOLT. I HAD ACCIDENTALLY TURNED IT OFF WHILE BEING ON THE HIGHWAY. THEY FIXED THAT DESIGN FLAW IN THIS 2017 MODEL. I HAVE SHARED MY THEORY WITH GM. GM/CHEVY HAS 3-WAY CALLED ME WITH THE "STOLEN VEHICLES DEPT". THEY AGGRESSIVELY DESCRIBE HOW THEY WON'T ISSUE A SLOW-DOWN THROUGH THE ON-STAR UNLESS THEY HAVE A REQUEST THROUGH POLICE, THE POLICE ARE BEHIND, THE LIGHTS BLINK, ETC. BUT, THEY'RE RELUCTANT TO SHARE WHAT HAPPENS NEXT. THEY'VE BEEN RELUCTANT TO SHARE HOW THEY TRACK YOUR VEHICLE THROUGH THE VIN AND GPS TRACKING. THEY'RE RELUCTANT TO SHARE THAT THIS SYSTEM CAN BE HACKED. IT IS EVIDENT THAT MUCH CAN GO WRONG ONCE THE ABILITY TO CONTROL YOUR CAR IS PLACED IN OTHER'S HANDS -- WHO AREN'T IN THE CAR DRIVING IT. THE DEALERSHIP COULD SEE THE CODE OF THE SLOW-DOWN. OF COURSE THEY WERE SURPRISED. THIS WASN'T JUST A "FAILURE". THIS IS A "FEATURE" IN THE CAR...BUT SOMEONE ELSE USED IT WITHOUT OUR PERMISSION. I WANT THE ON-STAR CONTROL DISABLED IN MY CAR!!! IT COULD HAVE KILLED MY DAUGHTER AND ME. IT COULD HAVE KILLED THE OTHERS WHO REPORTED A SIMILAR SITUATION.

AFTER TOW TRUCK CAME, THE CAR STARTED AGAIN AND I WAS ABLE TO DRIVE TO DEALER FOR REPAIR. DEALER FOUND TWO ERROR CODES IN THE HISTORY P0AC4 AND P0604. ALTHOUGH THE CAR IS WORKING FINE AT THIS MOMENT AND SEEMS LIKE IT WAS JUST SOME SORT OF COMPUTER CRASH, HOWEVER IT WAS VERY DANGEROUS TO LOSE PROPULSION ON THE FREEWAY AND STUCK ON A HEAVY TRAFFIC OFF RAMP.

IT HAPPENS WHILE DRIVING, BOTH ON THE FREEWAY AND SURFACE STREETS. AND JUST TO CLARIFY, I DON'T MEAN THE CAR WAS OUT OF ELECTRICITY OR OUT OF GAS (EACH TIME THIS HAPPENED, THE CAR HAD BOTH). WE WILL BE DRIVING ALONG WHEN, OUT OF THE BLUE, THE CAR SIMPLY JUST STOPS RUNNING, LEAVING US TO DO OUR BEST TO GET IT OUT OF THE ROADWAY WITHOUT GETTING HIT. THE CAR (WHICH ONLY HAS ABOUT 1,000 MILES ON IT) HAS BEEN IN THE SHOP OFF AND ON FOR ABOUT A MONTH NOW. WE HAVE BEEN VERY DISAPPOINTED BY HOW BOTH GM AND THE DEALER HAVE BEEN HANDLING THE SITUATION.

PE23022 · 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.
