2022-2023 Chevrolet Bolt EUV Problems & Issues

The 2022 Bolt EUV was swept into GM's expanded high-voltage battery fire recall. The Part 573 report for NHTSA 21V-650 lists 7,368 Bolt EUV vehicles built 2/18/2021 - 8/12/2021 alongside 45,049 Bolt EVs. GM and cell supplier LG Electronics identified the root cause as the simultaneous presence of two rare manufacturing defects in the same battery cell, aggravated by routinely charging to a full or nearly full state of charge after the pack has been substantially depleted. The pack may emit smoke or heat and can melt or damage the battery and surrounding vehicle structure. GM's interim guidance was extraordinary for a mainstream car: set Target Charge Level to 90%, charge more often, do not run the pack below roughly 70 miles of remaining range, and park outside immediately after charging rather than charging indoors overnight. This is the defining chapter of the EUV's short two-year life and the single most checkable fact about the car. Note that the earlier 21V560 campaign covered only 2017-2019 Bolt EV and does NOT include the EUV.

GM twice re-recalled Bolt EUVs that had already been 'fixed'. In June 2024, safety recall N242443000 / NHTSA 24V-481 covered 2020-2022 Bolt EV and 2022 Bolt EUV vehicles where GM's service records indicated the advanced diagnostic software remedy from 21V650 may not have been correctly installed. If that software is not properly loaded, the vehicle cannot identify defective battery modules that require replacement, so the fire risk from the original defect remains live and undetected. A second campaign, 24V-812, was issued in October 2024 for the same failure mode on a further subset. This matters because an owner or used-car buyer can see 21V650 marked complete on the VIN record while the car is functionally unprotected. The remedy is software-only and requires no parts.

GM TSB 22-NA-151 covers 2017-2022 Bolt EV and 2022 Bolt EUV and describes a distinct false-trip path from the U3636 issue. DTC P0BBD (battery pack voltage variation exceeded limit) sets without any true battery cell problem, and the vehicle then illuminates the MIL, displays 'Propulsion Power is Reduced', and refuses to charge above 30% state of charge. GM identifies two triggers: certain customer driving scenarios at very low vehicle speeds, notably applying the brake and accelerator simultaneously, and DC Fast Charging on certain models of chargers. The bulletin gives technicians a hard diagnostic discriminator - reading the GDS2 parameter 'Hybrid/Electric Vehicle Battery Pack Voltage Variation Exceeded Limit - Battery Cell'. If it reports cell number 20, 40, 67 or 87, the trip is software-induced; any other cell number means the pack is genuinely bad. This is the EV-specific counterpart to a false misfire code, and it is the mechanism behind a large share of Bolt EUV 'my car limited itself after fast charging' complaints.

Certain 2022 Bolt EUV vehicles are included in GM Service Update N232421261 for a possible false U3636 symptom 09. MIL, Reduced Propulsion and a 30% charging limit can also reflect a battery fault; these symptoms do not establish a software-only repair.

NHTSA recall 21V517000 (GM campaign N212340860) covers a small, precisely traced population that includes the 2022 Chevrolet Bolt EUV. One of the two fasteners securing the driver's frontal airbag module to the steering wheel may be missing or improperly tightened. If the module is not properly retained, the airbag may not deploy as designed in a frontal crash, increasing occupant injury risk. The affected count is very small - 28 vehicles across the campaign - so this is a targeted build-quality escape rather than a fleet-wide design defect, but it is a genuine open safety campaign that names this nameplate and is worth a VIN check on any early-build EUV.

GM TSB 19-NA-076, revised February 2023, lists the 2022 Chevrolet Bolt EUV among the affected vehicles. On shifting into Reverse the center display shows either a blue screen with a 'Service Rear Vision System' message or a black screen with a red triangle and a crossed-out camera icon, with no rearward image at all. The condition can persist for an entire power cycle and typically clears only after the A11 radio enters and exits a sleep cycle. GM attributes it to software anomalies in the Video Processing Module or the rear camera, not to a wiring failure. Because FMVSS 111 requires a rearview image, a car that intermittently shows no reverse camera is a real safety defect and not just an annoyance. On EUVs equipped with the standard rear view camera (RPO UVB) the radio stores history DTC B395A with symptom bytes 08, 72 and 3A.

GM TSB 19-NA-220, revised February 2023, explicitly covers 2022-2023 Chevrolet Bolt EUV. Customers experience an outright loss of propulsion - the car stops driving - and history codes P0A3F and sometimes P1B03 are stored in the Hybrid/EV Powertrain Control Module. The vehicle often operates normally again after a restart, which makes it dangerous and hard to catch. The cause is a spread (splayed) terminal at harness connection X2 on the T12 transmission/drive unit assembly, where terminals were not perfectly aligned during installation at the assembly plant. GM warns that terminals need not show visible damage to set the codes. Because these are resolver (motor position sensor) circuits, this is a genuine drive-unit interface failure, not a software trip, and it can drop propulsion at speed.
