2023-2024 BMW i4, i5, i7 Coolant Leak Delivery Stop

BMW has identified a potential issue with the coolant system in certain 2023-2024 i4, i5, and i7 electric vehicles. This concern, detailed in Service Information Bulletin (SIB) 64 06 24, involves the coolant changeover valve, which may develop a leak when exposed to temperatures significantly lower than 32° F (0° C). As a result, BMW has initiated a Delivery Stop to ensure all affected vehicles are repaired before reaching customers.

Important Warnings for Dealers and Owners

BMW has issued a critical directive regarding vehicles subject to this Delivery Stop:

"Do not deliver to a customer, a New, Certified Pre-Owned or Used vehicle subject to a Delivery Stop, until the vehicle is repaired. Do not use or sell replacement equipment/parts subject to a Delivery Stop."

This means that any new, certified pre-owned, or used vehicle identified under SIB 64 06 24 cannot be sold or delivered to a customer until the necessary repair has been completed. This measure is in place to ensure vehicle safety and proper function, particularly in cold climates where the BMW i5 coolant leak could occur.

The Situation: Coolant Changeover Valve Leak

Quality control checks revealed that the coolant changeover valve in certain BMW electric vehicles could develop a leak. This issue is specifically triggered by very low outside temperatures, defined as significantly below 32° F (0° C). Such a leak could compromise the vehicle's cooling system performance.

BMW AG officially issued this Delivery Stop, SIB 64 06 24, effective May 17, 2024, for the specified 2023-2024 model year vehicles.

Repair Procedure Summary

The correction for this issue involves replacing all coolant changeover valves in the affected vehicles. The procedure varies slightly depending on the number of valves present in the specific model. Technicians will follow detailed BMW repair instructions:

• For vehicles with one coolant changeover valve: Technicians will follow Repair Instruction 64 12 790, titled "Replacing the coolant changeover valve (After vehicle diagnosis) (coolant changeover valve 2 for high-voltage battery)." This applies to models like the G26 (i4 Gran Coupe BEV) and G70 (i7 Sedan BEV).
• For vehicles with more than one coolant changeover valve: Technicians will follow Repair Instruction 17 61 625, also titled "Replacing the coolant changeover valve (After vehicle diagnosis) (coolant changeover valve 2 for high-voltage battery)." This applies to models such as the G60 (i5 Sedan BEV), which has three changeover valves, requiring both Repair Instructions 64 12 790 and 17 61 625.

This repair is crucial to prevent the BMW i5 coolant leak and similar issues in other affected models.
