2023-2024 BMW iX Coolant Changeover Valve Delivery Stop

What's Happening: BMW iX Delivery Stop

BMW AG has issued a Delivery Stop, identified as Service Information Bulletin (SIB) 64 03 24, for certain Model Year 2023-2024 BMW iX vehicles. This bulletin, which is Revision 2, replaces the earlier SI B64 03 24 dated January 2024. This action addresses a potential issue with the coolant changeover valve.

The affected vehicles are the i20 E-Series, specifically the iX Sports Activity Vehicle (Battery Electric Vehicle), produced between March 10, 2023, and January 12, 2024. This delivery stop means that new vehicles cannot be delivered to customers until the required action is completed.

The Problem: Coolant Changeover Valve Leak

The core issue for the 2023 BMW iX coolant leak is that the coolant changeover valve may develop a leak. This condition is specifically triggered when outside temperatures drop below 19°F (-7°C) and the vehicle's operating systems have also been exposed to these low temperatures, such as being parked outside overnight. This can lead to a very small coolant leakage.

If a coolant leak occurs, owners may receive a Check Control message in their vehicle. The exact message displayed is: "Drive. It is possible to continue driving. Must be checked by the Service Partner."

Important Warnings for Owners and Dealers

BMW has made it clear that vehicles requiring this campaign must have the action completed before delivery. Dealers will see an "Open" status for this campaign when checking vehicles in AIR, AWP, Campaign Summary, or Warranty Vehicle Inquiry. As of January 26, 2024, dealers can access a list of affected vehicles in Inventory Campaign Details (ICD) under ROSS.

BMW is not notifying consumers directly about this delivery stop. Instead, the process involves the dealer informing the customer prior to vehicle delivery. If you are awaiting delivery of a new 2023-2024 BMW iX, your dealer should discuss this situation with you.

Dealer Action and Correction Procedure

Before delivering an affected vehicle, the dealer is required to discuss the situation regarding the potential 2023 BMW iX coolant leak with the customer. The customer must then sign an attached information letter, confirming they have been fully informed about the situation. This signed information letter must be enclosed with the sales contract.

For vehicles already delivered that experience a coolant leakage issue, or if a warning message appears, owners should contact an authorized BMW Center immediately for a service appointment. Any necessary coolant valve replacement will be performed at no charge under the BMW New Vehicle Limited Warranty.

For vehicles that do not experience a sealing capacity/coolant leakage issue, the BMW Service Center will conduct a check for any corrective measures needed during the vehicle's first regular service visit.

Warranty and Claim Information

Reimbursement for this action is processed via normal claim entry. The specific work package information is as follows:

Next Steps for Owners

If you own or are awaiting delivery of a 2023-2024 BMW iX produced between March 10, 2023, and January 12, 2024, and you have not yet been informed by your dealer, contact them to discuss the SIB 64 03 24 delivery stop. If you experience a coolant leak or see the message "Drive. It is possible to continue driving. Must be checked by the Service Partner.", schedule a service appointment with an authorized BMW Center.
