Service bulletins for the 2024 BMW i4

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

48 on file from NHTSA, as of 2026-10-19.

Bulletins, newest first
B6411242024-12-31. Service campaign. ELECTRICAL SYSTEM. Quality checks have determined that the coolant changeover valve may develop a coolant leak undervery low outside temperatures (significantly lower than 32º F (0 C)).
B6118242024-09-29. Service campaign. ELECTRICAL SYSTEM. A manufacturing defect in high-voltage cells of the high-voltage battery can result in electrolyte leakage which might result in a conductive connection with surrounding components. Depending on the contact resistance, a yellow or red Check Control message will then be displayed; it is permitted for you to continue driving, but this will result in a charging interruption during charging.

B6107242024-04-01. Service bulletin. ELECTRICAL SYSTEM. This Informational Bulletin is intended as a guided work through process to address BEV/PHEV charging issues. The step-by-step guide will help walk you through the correct “basic” steps that should be followed when addressing and diagnosing battery electric vehicles (BEV) and plug in hybrid vehicles (PHEV) charging issues.
B6106242024-04-01. Service bulletin. ELECTRICAL SYSTEM. This Informational Bulletin is intended as a guided work-through process to address customer charging complaints. The step-by-step guide will help walk you through the “basic” procedure to test the charger/infrastructure when the vehicle does not charge, either at a: Home charger AC Level 1/Level 2 - Flexible Fast Charger/hard wired Wallbox, or a Public AC Level 2, or DC Level 3 - Fast Charging Station Note: All PHEV and BEV vehicles may be affected.
B6112242024-04-01. Service bulletin. ELECTRICAL SYSTEM. BMW AG has issued a Delivery Stop (effective March 21, 2024) on certain Model Year 2023 - 2024 BMW vehicles that were produced between September 24, 2022, and December 14, 2023.
B6402242024-03-02. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM; ELECTRICAL SYSTEM. The coolant changeover valve may develop a coolant leak when the outside temperatures go below 19°F (-7°C). The vehicles operating systems would also need to be at that same low temperature (example: being parked outside, overnight in low temperatures).
B6103242024-03-02. Service bulletin. ELECTRICAL SYSTEM. Gen 5 BEV/PHEV vehicles may set the Combined Charging Unit (CCU) in programming abort due to nocommunication to the HV charge socket electronics.
B1205232024-03-02. Service bulletin. POWER TRAIN. The customer states there is a Drivetrain Malfunction message displayed in the instrument cluster. In addition, the following fault memory entries are saved in the CCU (Combined Charging Unit) 0317F2 - High-voltage system, insulation fault detected: when switch contactors are closed. 0317F1 - High-voltage system, insulation resistance below warning threshold: when switch contactors are closed. The fault memory entries (isolation faults) can occur both individually and in combination and must be traced back to the eDrive motor based on the ISTA test procedure. If ISTA test procedure lists possible cause of fault as; A metal chip is found behind the brush module (between the brush module and the end shield of the electrical machine). Repair required. Refer to service solution no. 20000794435083 in Aftersales Information Research (AIR). Follow information in the Procedure section below.
B6402242024-02-01. Service bulletin. ENGINE AND ENGINE COOLING. The coolant changeover valve may develop a coolant leak when the outside temperatures go below 19°F (-7°C). The vehicles operating systems would also need to be at that same low temperature (example: being parked outside, overnight in low temperatures).
B6113052024-02-01. Service bulletin. ELECTRICAL SYSTEM. The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle “discharged battery” complaints.

B6406232024-01-03. Service bulletin. ELECTRICAL SYSTEM. While the vehicle is at a standstill, a clicking noise can be heard in the passenger compartment. It must bequiet without other electrical loads or without driving noises to be heard. It sounds like the noise comes from under the hood.
B6125232023-11-01. Service bulletin. ELECTRICAL SYSTEM. The purpose of this Service Bulletin (SIB) is informational regarding DC (direct current) charging complaints on Gen 5 Battery Electric Vehicles (BEV). It serves as a supporting argument and is intended to help distinguish between a standard designed function or component operation from an actual system fault in a DC charging customer complaint (i.e., “DC Not charging or “DC charging too slow”. Helpful “Tips and Tricks” have been included on each topic within the document that can be used as reference to aid in the diagnosis or in understanding the system. The situation involves several possible causes: 1. Limitation of charging power by the charging station or charging app configuration. 2. Decreasing charging power at a very high state of charge (SoC). 3. Too frequent DC charging attempts within a short period of time. 4. The high-voltage battery is not at the ideal temperature. 5. Ageing of the high-voltage battery.
