When shifted into park, persistent error message that car was not in park. Unable to shut off the car despite numerous manipulations of shift. Few similar preceeding incidents were resolved by shift to drive then back to park. Goes to dealer tomorrow. Car running endlessly is dangerous. What if I could not stay with the car, or the car was on the local ferry. No one has inspected it yet. First time problem occured was in November 2024. Most recent more serious problem occured Friday. I am afraid to use the car since, and have not driven it since.

Two incidents related to the powertrain. 1) In December, 2023, the EV battery was drained and the car would not start based on the gas motor. The dealer fixed it in our recollection. 2) On [XXX], I was driving the car out of a Detroit Convention Center parking lot, going up the ramp when the car, with no warning, completely lost power and stopped. The message on the display said "Powertrain loss" or "Powertrain lost." I wish I had taken a photo of it, but I was panicked. Cars were backed up behind me on the ramp out of the parking garage, honking and having to back up. I tried turning the car off and on, googling the problem, and was about to call a tow truck when after 12-13 minutes, I was able to restart the car. I was scared that this could happen again on the freeway. When we could do it together, my husband and I took the car to Chevrolet Suburban of Ann Arbor, which says that they can find nothing wrong with the car, cannot replicate the problem, and that the car computer does not have any error code. They and GM are not willing to do anything to fix it. If they are really unable to find an error code, then something is wrong with the car computer too. I will not drive that car again until it is fixed - I consider it to be risking my life and others' lives to do so. We are spending a lot of money leasing a replacement vehicle as they will not even give us a loaner. The car is just sitting in their lot. And if we trade it in, will they resell it to someone else, potentially putting their lives at risk? - The vehicle is available for inspection at Chevrolet Suburban Ann Arbor. - My safety was at risk. So was that of other drivers around me. I could have been rear-ended. - The problem has not been reproduced/confirmed. - The vehicle and component have not been inspected by the manufacturer, police etc to our knowledge. - There was NO warning ahead of time and no symptoms prior to the problem. The warning message displayed simultaneously with the problem INFORMATION REDACTED PURSUANT TO THE FREEDOM OF IN

Mileage: 38523 Engine Not Available Service Soon Propulsion Power Is Reduced Fuel Range Low: 3/4 Tank full of gas [XXX] - I was driving Northbound on [XXX] South of Castlewood in Northern California. I was driving 70 mph when I suddenly received the error messages above on my dashboard screen. The vehicle immediately had power from 70 mph quickly going below 59 mph. The traffic was extremely high and I had to quickly use my hazard flashes and carefully maneuver to the right shoulder of the frwy. The vehicle lost power so quickly I could have easily been rear ended or in a serious vehicle accident. The dealer test drove the vehicle and stated they received the errors at 95 mph. The dealership is recommending I have the entire transmission replaced with the assembly and the 45,000 mile maintenance. No other warning lamps, messages or symptoms or failures occurred.

Intermittently, the car would not turn off, starting in about July, 2022. After shifting the car into park and pressing the On/Off switch, the car displayed a message like "Action required. Shift to park". It was impossible to know if the car really was not in park, and would roll into someone, and it was certainly unsafe to walk away and leave the car "on". A Chevy forum showed that this problem is COMMON and pointed me to GM TSB 19-NA-206 (https://static.nhtsa.gov/odi/tsbs/2020/MC-10171895-9999.pdf). The TSB exactly describes the symptom I observed and lists one of the exact parts that the Huston Chevrolet service department replaced on 8/3/2022 - 84733196 N-Harness. The dealer, Chevrolet customer service, and GM customer service all told me that this repair was not covered under warranty, though the TSB says this on page 4: "Specific to the Volt model, repairs are covered under the Voltec (Electric and Hybrid Vehicle) Warranty." GM said that I would have received a letter if the TSB applies to my specific car. I paid Huston Chevrolet $446.79 to repair this problem, and believe the manufacturer should 1) reimburse me for the cost and 2) notify other owners about this common and dangerous manufacturing defect.

2PE23022 · Loss Of Motive Power Due To The Battery Energy Control Module
Opened Nov 29, 2023 · Closed Mar 3, 2025

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.
