I HAVE HAD 3 BLOWOUT AND ONE MORE TIRE THAT HAS HAD SIDE WALL DAMAGE AND HAD TO BE REPLACED. THE CAR HAS 29,289 MILES ON IT. THE 1ST BLOW OUT WAS AT JUST OVER 7,000 MILES. AFTER THE 2ND BLOW OUT ON THE ORIGINAL TIRES AND BEING STRANDED WITHOUT A SPARE TIRE. WHICH MAKES ME WAIT HOURS FOR A TOW TRUCK. I PURCHASE BRIDGESTONE DRIVE GUARD RUN FLAT TIRES. I HAVE HAD TO REPLACE 2 MORE OF THESE ONE WAS A BLOW OUT AND THE OTHER WAS SIDE WALL DAMAGE IT WAS FOUND WHILE THE VEHICLE WAS GETTING A PUNCTURE FLAT FIX. I THOUGHT THE STIFFER SIDEWALL OF THE RUN FLAT TIRE WOULD HELP BUT IT HAS NOT. I BELIEVE THAT THE 3,500 LBS WEIGHT OF THE VEHICLE COMBINED WITH 17 RIMS AND 50 SERIES LOW PROFILE TIRES IS CAUSING THE SIDE WALL OF THE TIRES TO BE CUT BY THE METAL RIM WHEN CHUCK HOLES ARE HIT. I'VE BEEN DRIVE 42 YEARS AND HAVE NEVER HAD A CHUCK HOLE CUT A TIRE LET ALONE 4 TIRES IN 22,000 MILES. THESE DAMAGED SIDE WALLS HAVE ALL BEEN ON CITY STREETS IN NORTH EASTERN OHIO AKRON, AND CLEVELAND AREA. THE SAME STREETS I'VE DRIVEN CARS ON FOR THE PAST 29 YEARS WITHOUT THIS ISSUE. THIS CAR IS BASICALLY A CHEVY CRUZ WITH 700LBS MORE WEIGHT DUE TO THE BATTERIES. THE CRUZ HAS 15 IN WHEELS, 16 IN WHEELS. AND 17 IN WHEELS. I BELIEVE THE ADDITIONAL WEIGHT 700 LBS COMBINED WITH THE SHORT 205/50/17 SIDE WALL TIRE .. THE CRUZ'S USES 215/50/17 TIRES IS THE CAUSE OF ALL THESE TIRE FAILURES. I DO NOT HAVE THE TIRE INVOICES WITH ME NOW TO VALIDATE THESE CLAIMS BUT I CAN PROVIDE THEM AT A LATER DATE. SHOULD YOU REQUIRE THEM.

THE CONTACT SOUGHT MEDICAL ATTENTION APPROXIMATELY TWELVE TIMES AND WAS TO THE POINT OF ALMOST NEEDING A CANE AND A WHEELCHAIR. THE CONTACT STATED THAT APPROXIMATELY 48 HOURS AFTER BEING AWAY FROM THE VEHICLE, HIS HEALTH BEGAN TO IMPROVE SIGNIFICANTLY. AS THE FAILURE PROGRESSED, THE CONTACT DOWNLOADED AN APP THAT TESTED FOR SIGNS OF ELECTROMAGNETIC RADIATION. THE APP RESULTS IDENTIFIED HIGH LEVELS OF RADIATION IN THE VEHICLE. THE FOLLOWING DAY, THE CONTACT TOOK THE VEHICLE TO MEDVED CHEVROLET (11001 W INTERSTATE 70 FRONTAGE RD N, WHEAT RIDGE, CO 80033, 888-730-2381) TO SHARE THE APP FINDINGS. WITH THE HELP OF THE MANUFACTURER, THE DEALER CONCLUDED THAT THERE WERE HIGH LEVELS OF RADIATION INSIDE THE VEHICLE. THE CONTACT WAS ADVISED TO STAY OUT OF THE VEHICLE. THE CONTACT SHARED THAT THE VEHICLE HAD SOME ELECTRICAL REPAIRS PERFORMED PREVIOUSLY; HOWEVER, HE WAS INFORMED THAT IT WAS UNRELATED TO THE RADIATION FAILURE. THE CONTACT ALSO STATED THAT THE LOCATION OF WHERE THE VEHICLE WOULD CHARGE OVERNIGHT WAS ADJACENT TO HIS BEDROOM, WHICH COULD HAVE BEEN A CONTRIBUTING FACTOR TO HIS DECLINING HEALTH. THE CONTACT SUBMITTED A CLAIM WITH THE MANUFACTURER, WHICH INCLUDED A STATEMENT OF EVERYTHING HE EXPERIENCED, VIDEOS, AND PHOTO EVIDENCE; HOWEVER, HIS CLAIM WAS DENIED. THE FAILURE MILEAGE WAS APPROXIMATELY 47,000.

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.

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.
