Research checked 2026-10-24. Individual vehicle eligibility must be confirmed with the manufacturer or regulator.
The official action and its boundaries
On 2021-08-20, the responsible Canada record documented campaign 2021-524 involving Bolt EV; Bolt EUV. Its published coverage is 2020-22 EV; 2022 EUV (Canada model-year listings). This is a dated summary of a specific official safety action, not a new mechanical diagnosis or a claim about the whole global nameplate.
The notice qualifies applicability as follows: Certain 2020-22 Bolt EV and 2022 Bolt EUV in Transport Canada 2021-524; excludes unrelated Chevrolet EVs. Transport Canada publishes a Canadian campaign identifier. It should remain distinct from a similarly named American campaign, and the Canadian manufacturer must confirm the individual VIN and whether the stated repair has been carried out.
The identified safety concern
The regulator or manufacturer describes this concern: High-voltage battery may overheat when charge exceeds 90 percent creating smoke/heat and fire risk. It is an identified possibility within a defined campaign, not a prediction that an owner’s vehicle will fail. The population count, where supplied, means potentially involved vehicles, not that every vehicle in the list actually experienced the hazard or that a specified percentage failed.
The Canadian notice documents an updated diagnostic-and-module response, which must not be misreported as an unconditional battery-pack replacement for every listed model year. Owners need the current VIN-specific recall condition and any interim-use restrictions directly from General Motors.
Remedy recorded in the official notice
The source’s documented corrective approach is: Advanced diagnostic software; module replacement when triggered by detected condition. This is the notice/remedy evidence available in the source reviewed on 2026-10-24; it does not establish that work has been completed on any particular vehicle.
Safety campaign documents may be amended, expanded or replaced. Confirm the current instructions and open/closed status with the official brand network using the vehicle identity. Do not carry out unapproved repairs or deliberately recreate the alleged fault to see whether the car qualifies.
What an owner or used-car buyer should do
The used-Bolt inspection should include the charging history only insofar as a dealer can assess it and, most importantly, evidence of completed campaign work. Never open a traction battery or recreate an old charging-limit instruction without checking current manufacturer advice.
Retain the country, campaign ID 2021-524, original notice date and dated repair confirmation in the vehicle history. If you experience hazardous steering, braking, sudden propulsion loss, smoke, fire or loss of visibility, follow the vehicle maker’s emergency instructions and obtain professional assistance. The presence of this recall is not an independent reliability score for the model line.
