Manufacturer summary

Original wording in English

Certain 2020 – 2022 model year Chevrolet Bolt EV and 2022 model year Chevrolet Bolt EUV vehicles may have a condition in which a false diagnostic trouble code (DTC), U3636 symptom 09, is triggered. This false DTC is resulting in customers experiencing a Malfunction Indicator Lamp (MIL) illuminated in the Driver Information Center (DIC), a Reduced Propulsion message, and a charging limited to 30% State of Charge. Since this is a false DTC, it can lead to unnecessary battery pack replacements. Dealers are to reprogram the Hybrid Powertrain Control Module 2 and provide the customer with a free NACS Adapter.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
