Urgent Subject: BMW Recall 23V-xxx: Transmission Mechatronics
BMW AG has issued a Delivery Stop (effective September 28, 2023) on certain Model Year 2023 BMW vehicles that were produced between January 23, 2023, and June 15, 2023. As of December 4, 2023, this Delivery Stop has been upgraded to a Safety Recall. The Integrated Transmission Control Unit (ITCU) may not have been produced according to specifications by the supplier. A weld seam may not have been manufactured correctly. Over time, this could allow transmission oil to leak into the ITCU which could affect functionality of the transmission. The revised Bulletin, Recall Notice and FAQ have been attached for further information. The bulletin will be updated when additional information becomes available.
Sincerely, Technical Service

Description of the Defect : The integrated transmission control unit, which is part of the transmission mechatronics module, may not have been produced according to specifications by the supplier. Specifically, the weld seam of the two halves of the control unit’s housing / cover may not have been manufactured properly. As a result, this could allow automatic transmission oil to leak into the transmission control unit which could then contact electronic components. If this happened, it could affect the operation of the clutch pressure control valves.

Saarbruecken Foreign States 66117
Country : Germany Chronology :
On July 13, 2023, BMW became aware of a possible issue involving the Integrated Transmission Control Unit (ITCU) from its supplier. The supplier indicated that during certain quality assurance tests, some parts became suspect. As a result, additional parts which had successfully completed the tests and that had been retained, were then subject to further testing and analyses, including photo-microscopy. The micrographs indicated that some portion of the welding seams may have been suspect. Additional testing, involving shaker tests to simulate long term durability, were performed. Between August and September, further in-depth reviews of the information and data provided by the supplier were conducted. This led to further requests for additional information and data from the supplier involving production process testing details, production lot information, and scope parameters. In October and November, further evaluations were conducted, including failure modes and affects analyses. Information from the field was reviewed to determine if any vehicles had experienced the issue. Vehicle assembly information and supplier production and process records were reviewed to determine the number, and production dates, of potentially affected vehicles. On November 29, 2023, BMW decided to conduct a voluntary safety recall. During its analyses, BMW was not aware of any customer complaints, warranty claims, or field reports that may be related to this issue and, similarly, Toyota was not aware of any non-dealer field reports or warranty claims that may be related to this issue. BMW and Toyota have not received any reports, nor are BMW and Toyota otherwise aware, of any accidents or injuries that may be related to this issue. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-821

The information contained in this report was submitted pursuant to 49 CFR §573
Description of Remedy :
Description of Remedy Program : The transmission mechatronics module, which contains the integrated
transmission control unit, will be replaced. If necessary, the automatic transmission fluid will also be replaced.
Owners will be notified by First Class mail advising them of the recall and to schedule an appointment with an authorized BMW / Toyota dealer to have the remedy performed for free. If this condition were to occur to a potentially affected vehicle prior to this recall, the remedy would be covered by the BMW / Toyota New Vehicle Limited Warranty program.
Therefore, reimbursement for a pre-notification remedy re Part 573.13 and Part 577.11 is not necessary.
