CHEVROLET SERVICE CASE [XXX] 5/20/19 FOR SAME ISSUE DESCRIBED BELOW SERVICE AT VICTOR CHEVROLET VICTOR CHEVROLET REPLACED BRAKE CALIPERS PROBLEM WAS MINIMIZED FOR A SHORT TIME. 8/27/19 -- BROUGHT THE VEHICLE TO VICTOR CHEVROLET FOR THE SECOND TIME FOR THE SAME PROBLEM * CLUNK IN REAR OF CAR AS IT STOPS. PREVIOUSLY, THE PROBLEM STARTED SMALL AND GOT PROGRESSIVELY WORSE WITH TIME. THE CLUNK MOVES THE CAR SLIGHTLY FORWARD; IT MOVES MORE AS THE PROBLEM WORSENS. * CAR HAS 6700 MILES NOW. IT HAD ABOUT 4500 MILES LAST TIME (VICTOR CHEVY CAN CONFIRM OR CORRECT) 8/30/19 -- CALLED VICTOR CHEVROLET SERVICE. NIKKI TOLD ME THAT THEY TESTED ANOTHER VOLT AND IT HAS THE SAME ISSUE, SO THIS ISN'T A PROBLEM. I SAID IT BECOMES PROGRESSIVELY WORSE, AND NEEDS BE FIXED, AS IT IS A SAFETY ISSUE. AT THE VERY LEAST, I OUGHT NEVER TO HAVE TO PAY FOR FIXING THE ISSUE OR RELATED PROBLEMS REGARDLESS OF THE STATUS OF MY WARRANTY. NIKKI SAID I NEED TO CALL AND TALK TO SERVICE MANAGER (GARY). I SAID HE NEEDS TO RESEARCH AND GIVE ME MORE INFORMATION; I WILL CALL CHEVY MEANWHILE AND CONSULT WITH THEM. 8/30/19 -- CALLED CHEVY (C/S) 800 888 1020 -- JULIAN WILL ESCALATE TO SENIOR ADVISOR TEAM. THEY SAY TWO BUSINESS DAYS. THAT MEANS WEDNESDAY. TODAY IS FRIDAY. CASE NUMBER [XXX] GOALS: 1) KEEP COMMUNICATION IN WRITING AS MUCH AS POSSIBLE SO NO MISUNDERSTANDINGS 2) FIX THE ISSUE. SOUNDS LIKE MAYBE THERE IS A RECALL NEEDED IF MANY VOLTS HAVE THE SAME PROBLEM. PERHAPS CHEVY CORPORATE CAN RESEARCH THE PROBLEM AND MINIMIZE TRIPS TO SERVICE (UGH. SUCH A HASSLE TO DROP OFF A CAR) 3) IF ISSUE CAN'T BE FIXED, OBTAIN IN WRITING FROM CHEVY A WAIVER SO THAT ANY FUTURE REPAIRS DIRECTLY OR INDIRECTLY RELATED TO THIS PROBLEM ARE WARRANTY COVERED INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TT

WHEN MY GAS ENGINE IS WARMED UP AND UP TO OPERATING TEMPERATURE, THERE WOULD BE THIS BURNT PLASTIC SMELL COMING FROM UNDER THE HOOD. IT'S BEEN HAPPENING LIKE THIS FOR THE PAST 3000 MILES OR SO. IT'S A CLEAR BURNT PLASTIC SMELL FROM UNDER THE HOOD, AND IT IS ALWAYS AFTER THE ENGINE IS COMPLETELY WARMED UP. I USE MY GAS ENGINE ALL THE TIME. THE DEALERSHIP CLAIMS IT IS NORMAL FOR HYBRID TO BURN STUFF OFF AS IT ISN'T RUN ALL THE TIME, BUT THE CAR HAS 6700 MILES. IT'S A STRETCH TO BLAME IT ON BREAK IN OIL. SOME OF THE SMELL GETS INTO THE CABIN WHEN I AM STOPPED, BUT IT IS VERY STRONG WHEN I GET OUT THE CAR AND WALK BY. IT'S BEEN HAPPENING FOR A FEW MONTHS NOW.

ONCE THE VEHICLE WAS STOPPED AT THE TRAFFIC LIGHT, THE DRIVER SHIFTED TO PARK AND WAS NOT ABLE TO PULL DOWN TO DRIVE AGAIN. VEHICLE WAS STRANDED IN THE MIDDLE OF THE ROAD WHILE CARS WERE APPROACHING FROM BEHIND WITH HIGH SPEED. AFTER REPEATED ATTEMPTS TO PRESS THE VEHICLE 'START' BUTTON, WE FINALLY WERE ABLE TO PULL DOWN TO NEUTRAL AND PUSHED THE VEHICLE TO THE SIDE OF THE ROAD. VEHICLE NEEDED TO BE TOWED TO DEALERSHIP FOR DIAGNOSIS.

I RAN INTO A VEHICLE IN FRONT OF ME DURING NORMAL TRAFFIC ON MY WAY HOME FROM WORK, TWO MONTHS TO THE DAY OF PICKING UP MY 2018 VOLT. THE VEHICLE AHEAD OF ME MAY HAVE STOPPED QUICKLY, BUT IT WAS NOT A STOP THE VOLT SHOULDN'T HAVE BEEN ABLE TO HANDLE. I WAS ON A STREET IN MY NEIGHBORHOOD I DRIVE EVERY DAY IN TRAFFIC. I HAD MENTIONED TO FRIENDS AND FAMILY THAT THE VOLT'S BRAKES JUST DID NOT FEEL ON PAR WITH THE REST OF THE CAR AND WOULD BE THE ONLY ASPECT OF THIS EV EXPERIENCE I FOUND LACKING. I HAVE THE DATED TEXT MESSAGES TO PROVE THIS. NOW I HAVE A VOLT AT THE BODY SHOP FOR THE 5TH WEEK (LACKING AN AC LINE FOR REASSEMBLY), AN OVER 55% INCREASE IN MY INSURANCE PREMIUMS (PER THE RENEWAL NOTICE I JUST RECEIVED) AND WHAT REALLY HASN'T BEEN A GOOD EXPERIENCE. WHILE I'M WAITING FOR THE RETURN OF MY VOLT I HAVE RECEIVED THE IMPORTANT SAFETY RECALL INDICATING THE BRAKING PERFORMANCE MAY BE REDUCED. IF THE CAR HAD BEEN ABLE TO STOP TWO FEET SHORTER I'D HAVE AN UNDAMAGED THREE MONTH OLD VOLT AND MY INSURANCE STANDINGS UNTARNISHED. THAT TWO FEET ENDED UP COSTING OVER $17,500 TO THE CAR. TURNS OUT VOLTS ARE ALSO EXPENSIVE TO REPAIR. I'M A 55 YEAR OLD MALE, NO WILD KID. STILL STUNS ME THAT IN 2018 GM CAN'T GET BRAKES RIGHT...THE MOST IMPORTANT OF SAFETY SYSTEMS.

Official recalls
2Sep 26, 2018
General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Consequence & remedy
Consequence: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.
Remedy: GM will notify owners, and dealers will inspect the rear seatbelt retractors and replace them if necessary, free of charge. The recall began November 7, 2018. Owners may contact Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 18315.

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.
