G26 i4, iX & i7 problems (2022–present)

High-voltage battery may short circuit (fire risk) (2022–2023)

Safety recall
Chassis:
G26 i4 eDrive40 and M50; I20 iX xDrive50 and M60
Years:
2022–2023
Engine:
eDrive electric (Gen5)

BMW recalled a group of early i4 and iX models in 2022 because internal damage in the high-voltage battery could cause a short circuit. NHTSA notes this raises the risk of a fire, and owners were advised to park outside until the repair. The remedy is a replacement battery.

Symptoms

  • High-voltage system warning
  • No symptoms in many cases

Check before buying

  • Enter the VIN at nhtsa.gov/recalls or ask a BMW dealer to confirm the recall work was completed

NHTSA recall: 22V-541 (2022-07) · 367 vehicles

Battery control software can cut drive power (2022–2023)

Safety recall
Chassis:
G26 i4; I20 iX; G70 i7
Years:
2022–2023
Engine:
eDrive electric (Gen5)

Software in the high-voltage battery's control unit on 2022–2023 i4, iX and i7 models could interrupt electrical power, causing a sudden loss of drive. Dealers or over-the-air updates install corrected software. A related 2023 campaign (23V-295) covered battery cell-monitoring connections that could also cut power.

Symptoms

  • Sudden loss of drive power
  • Drivetrain warning message

Check before buying

  • Enter the VIN at nhtsa.gov/recalls or ask a BMW dealer to confirm the recall work was completed
  • Check 22V-944 and 23V-295

Battery module weld seams can overheat (2024 i4) (2024)

Safety recall
Chassis:
G26 i4 xDrive40 and M50 (also i5)
Years:
2024
Engine:
eDrive electric (Gen5)

In early 2024 BMW recalled some 2024 i4 and i5 models because high-voltage battery modules may have insufficient weld seams. That can let the battery overheat, which increases fire risk. The affected battery modules are replaced.

Symptoms

  • High-voltage battery warning

Check before buying

  • Enter the VIN at nhtsa.gov/recalls or ask a BMW dealer to confirm the recall work was completed

NHTSA recall: 24V-135 (2024-02) · 4 vehicles

Left longitudinal beam may crack (2024 i4) (2024)

Safety recall
Chassis:
G26 i4 eDrive40, xDrive40 and M50
Years:
2024
Engine:
eDrive electric (Gen5)

A batch of 2024 i4s was recalled because the left-side longitudinal beam in the body structure may crack. That reduces crash protection for the high-voltage battery and raises the risk of fire after a collision. BMW inspects and repairs affected cars.

I20 i4, iX & i7 problems (2022–present)

Battery cell modules may be assembled improperly (2022–2025)

Safety recall
Chassis:
I20 iX; G70 i7; G26 i4
Years:
2022–2025
Engine:
eDrive electric (Gen5)

In mid-2025 BMW recalled iX, i7 and early i4 models because some high-voltage battery cell modules may not have been assembled correctly, stressing the module frame. A failed module can shut down the high-voltage system and cause a loss of drive. A separate 2025 campaign (25V-395) updated electric-motor software that could also shut down the high-voltage system.

Symptoms

  • Loss of drive power
  • High-voltage system warning

Check before buying

  • Enter the VIN at nhtsa.gov/recalls or ask a BMW dealer to confirm the recall work was completed
  • Check 25V-470 and 25V-395

NHTSA recall: 25V-470 (2025-07) · 136 vehicles

G70 i4, iX & i7 problems (2023–present)

Integrated braking system (IBS) can fail (i7) (2023–2025)

Safety recall
Chassis:
G70 i7 eDrive50, xDrive60 and M70
Years:
2023–2025
Engine:
eDrive electric (Gen5)

The i7 shares the 7 Series integrated-brake recalls. Welds in the brake unit's servomotor can break, cutting power assist and rear braking and disabling ABS and stability control. i7s appear in 24V-697, 24V-739 and the 2026 campaign 26V-422. Dealers replace the unit.

Symptoms

  • Brake or stability-control warnings
  • Hard brake pedal

Check before buying

  • Enter the VIN at nhtsa.gov/recalls or ask a BMW dealer to confirm the recall work was completed
  • Check every IBS campaign against the VIN

I01 i4, iX & i7 problems (2014–2021)

Electric motor electronics can shut down propulsion (i3) (2018–2019)

Safety recall
Chassis:
I01 i3 BEV and REx
Years:
2018–2019
Engine:
eDrive electric; REx range extender

A circuit-board problem inside the i3's Electric Motor Electronics module could shut off high-voltage power, ending propulsion. BMW recalled 2018 cars and then 2019 cars (19V-599). Dealers replace the EME module.

Symptoms

  • Sudden loss of drive power
  • Drivetrain malfunction warning

Check before buying

  • Enter the VIN at nhtsa.gov/recalls or ask a BMW dealer to confirm the recall work was completed
  • Check both 19V-310 and 19V-599

NHTSA recall: 19V-310 (2019-04) · 159 vehicles
