General Motors has issued a service update for the 2020 through 2022 Chevy Bolt EV and 2022 Chevy Bolt EUV to address a problem with the vehicles’ internal mileage counter.
Service update N23432430 states that certain units of the Bolt EV and Bolt EUV may have a condition in which the internal mileage counter has been reset with an EV powertrain module reprogramming event, which may cause the battery state of charge to be limited to 80 percent beyond the required 6,231-mile (10,000 km) specification.
In order to fix the problem, a dealership technician will verify the mileage of the Bolt EV and Bolt EUV and then reprogram the EV Powertrain Control Module 2, which will return the charge limit to 100 percent after the mileage threshold is reached. This service must be completed at an authorized EV dealer, and the technician must have successfully completed the required technical training. Because this is a service update, not a recall, it will remain in effect through April 30th, 2026.
It’s worth noting that owners of the 2020 through 2023 Chevrolet Bolt EV as well as the 2022 and 2023 and Bolt EUV may be eligible for a $1,400 compensation if they opt to install the final advanced diagnostic software. Said software limits the maximum charge of the battery on Chevy Bolt units to 80 percent, thereby preventing the fire hazard that may result from a 100 percent charge. The software continues to analyze the battery’s performance during subsequent driving and charging by the vehicle’s owner. After at least 6,200 miles, the software will remove the 80 percent charge ceiling, enabling the battery to take a full charge again as normal.
Additionally, GM released a pair of service updates to address an issue with the Chevy Bolt EV and EUV, which may have been fitted with a mislabeled high-voltage battery, and a mislabeled high-voltage battery requiring an update to the vehicle calibration to match the battery chemistry. Another service update regarding the high-voltage battery has been released, as the battery may not have been torqued to spec during assembly.

Classic GM BS.
Your statement is wrong regarding 2020 to 2023 having the battery hazard issue. It’s 2017-2021 models that have been recalled
James, the battery hazard recall and the service update described in this article are specific to recalled 2020-2022 Bolts. 2017-2019 Bolts had a separate recall and are not affected by this issue. Some 2022s were also recalled and are affected.
Are you sure it says 2020-2022?

Well, I hope that GM rethinks their strategy of not allowing Apple Car Play or Android Auto integration with the next generation of Bolt.
I own a 2023 Bolt EUV and in no small part, made the decision to buy it based on Apple Car Play working on the car. It is also the primary reason why I never seriously considered purchasing a Tesla.
