  • Where these come from. The federal recall record, not a forum
20V-701
2017 to 2019 Bolt EV · 50,932 unitsSoftware only. The propulsion control module was reprogrammed to limit full charge to 90 percent. NHTSA's record says this recall has been superseded.
21V-560
2017 to 2019 Bolt EV previously recalled under 20V-701 · 57,414 unitsDefective battery modules replaced free of charge.
21V-650
2020 to 2022 Bolt EV and 2022 Bolt EUV · 52,414 unitsSame defect and the same module replacement remedy. Owner letters went out 1 October 2021 and 23 June 2023.

What was actually done

NHTSA's remedy text says modules, not packs. In practice GM deployed diagnostic software that flags defective modules, so some cars got a full pack assembly, many got module sets, and some got software plus a clean diagnostic result. Anyone telling you every Bolt got a brand new pack is wrong.

If you are buying one

Run the VIN through NHTSA and through GM's own owner lookup. If 21V-560 or 21V-650 shows as open or incomplete, the remedy has not been done. Ask the dealer to pull the service history for battery pack or module part numbers. GM's Bolt concierge line is 1-833-382-4389.

Not confirmed. The commonly repeated eight year and 100,000 mile warranty on a replacement battery could not be confirmed, because GM's media and consumer sites refused automated access. Ask the selling dealer for the battery replacement warranty start date in writing rather than trusting a forum post.

Buying a Used EV or Hybrid?

Get the battery measured before you pay for it. A PPI Auto inspector tests the pack on the car you are looking at and sends you the numbers. Starting at $225.
