NHTSA Complaint #11711001 — 2016 CHEVROLET VOLT

While I driving in the past week, a warning that "propulsion power reduced" appeared on my dashboard several times. The last time that I had driven the car, the heater would not turn off, and the smell of burnt rubber filled the car and then dissipated soon after. The car would only run in it's gas engine mode, and not switch over to electric mode, as it usually would. The next morning, the car would not start. The dash board would light up as if the car started, but when I shifted into drive, a warning appeared on the dash, "Shift to park", as it would when the car is not running. I could not start the vehicle. After plugging the vehicle in, a warning appeared on the console stating that "Charging is not available". The car was towed to the dealership. Their diagnosis showed that the Battery Energy Control Module had failed and must be replaced. They later confirmed that an electric cable needed to be replaced that was "corroded", but they could not confirm the cause of the corrosion because the cable was disposed of already. After researching online, I found that GM issued a Special Coverage bulletin: N232432680, citing a common malfunction of the Battery Energy Control module in 2016 to 2018 Chevy Volts that "causes a reduced power mode, a no start condition, or a no charge condition." The Special Coverage was to extend the warranty to 15 years or 150,000 miles. After inquiring the dealer about the Special Coverage, they claimed that our car is not covered under the warranty. After calling customer service, they claimed the coverage comes from NHTSA, and GM only issues orders by VIN, and therefore cannot cover the issue. After calling NHTSA, I was told the special coverage is not a national recall, and is internal to GM. The GM dealership still claims that the control module on our car is not covered under the warranty, and have denied the request for a manager inspection or investigation.
