BMW of North America is recalling more than 100,000 2019-2020 X5, X7, 2020 3 Series Sedan, X6, 2020-2021 7 Series Sedan, 2020 8 Series Convertible, 8 Series Coupe, and 2020 8 Series Gran Coupe vehicles. In the event the starter motor fails, repeated attempts to start the vehicle can cause the starter motor to overheat from an electrical overload.
“In certain cases in which the engine starter has some mechanical damage, the engine may not be able to be started. If the driver repeatedly attempts to start the engine using excessively long starting attempts, this may cause an electrical overload of the starter. If the engine acoustic protection material is contaminated by, e.g. oil, then in an extreme case, the proximity of the starter to the acoustic protection material could lead to a thermal event,” BMW said in the required filing which the National Highway Traffic Safety Administration made public this morning. “Thermal event” is a fire in recall speak.
Chronology
- In March 2023, after receiving several field reports regarding engine no-start conditions and indications of local thermal damage within the engine compartment, an engineering investigation was initiated. Initial reviews found that there were only a few reports of thermal damage when compared to a larger number of engine no-start conditions. At that time, it was not yet clear if there was a direct relationship between the engine starter and the observed damage within the engine compartment. The field continued to be monitored.
- By August 2023, various groupings of components were established based upon reviews of damaged hardware from the field. Possible fault patterns that could result in the observed damage were discussed.
- By November, additional analyses included a review of the records regarding starter failure and the specific number of attempted engine starts. A review of supplier production records was also conducted. Several additional field incidents were reported.
- Between January and June 2024, further reviews pointed to specific engine starter production configurations that could be associated with the reported field cases. By June, several additional field incidents were reported. Vehicle assembly information and supplier production records were reviewed to determine the number and production dates of potentially affected vehicles.
- On 25 July 2024, BMW decided to conduct a voluntary safety recall.
BMW has not received, nor is BMW otherwise aware, of any accidents or injuries related to this issue. BMW is aware of approximately twelve customer complaints and associated field incidents related to this issue.
