2021-2023 Mini Cooper SE Vehicle Stall And Potential Battery Fire

Posted on by

Mini CooperA manufacturing issue was identified in a small batch of 2021-2023 Mini Hardtop 2 Door Cooper SE vehicles. These electric cars were found to have a high voltage battery housing that did not meet the company’s assembly specifications. This discovery came to light after a concerning incident in the U.S. in October 2023, where one such vehicle experienced what is known as a thermal event—a significant overheating.

Following this incident, BMW initiated a thorough engineering analysis to pinpoint the cause. It was found that during certain production periods, there was a flaw in how the battery housing was sealed. Specifically, an inadequate amount of sealing compound was applied between the two halves of the battery module’s housing. This oversight made it possible for water to seep into the battery enclosure.

Water entering the high voltage battery compartment can trigger what is called an isolation fault. This type of fault compromises the battery’s integrity, leading to performance issues and safety concerns. Initially, such water ingress prompts the vehicle to display a warning message, alerting the driver of the fault and advising them to have the vehicle checked at a MINI service center.

Should the water exposure continue, the situation can escalate. The accumulation of moisture can cause multiple isolation faults, potentially causing the vehicle to stall. In more severe cases, particularly after long periods of inactivity, these faults could cause the battery to overheat significantly. Such overheating, while rare, could lead to a thermal event, even if the car is not in use.

To address this issue, BMW is recalling affected vehicles to inspect, and if necessary, repair the sealing of the battery housing. This includes a thorough leak test to ensure the integrity of the battery enclosure. Owners of the affected Mini Cooper SE models will be notified by mail with instructions to visit their dealer. Notification letters are scheduled to be sent out on June 21, 2024. The recall has been officially recorded under the NHTSA campaign number 24V-302.

Vehicle owners are encouraged to respond to the recall notice promptly to ensure their safety and the proper functioning of their vehicle.

Ford Mustang Mach E Battery Contactor Could Overheat

Posted on by

Certain 2021-2022 Ford Mustang Mach-E cars might face a power problem due to an overheated high voltage battery contactor, potentially leading to an increased risk of accidents.

In June 2022, Ford’s Field Review Committee (FRC) gave the green light to a Field Service Action (FSA) named 22S41, specifically designed to tackle concerns regarding the overheating of the high voltage battery main contactor in select 2021-2022 Mustang Mach-E vehicles. To fix this issue, dealers updated the software for the Secondary On-Board Diagnostic Control Module (SOBDMC) and the Battery Energy Control Module (BECM). The enhanced SOBDMC software keeps an eye on the contactor’s temperature and smartly reduces the battery’s power output to prevent further damage. Meanwhile, the upgraded BECM software checks the contactor’s resistance to identify any damage, then it generates a diagnostic trouble code (DTC) and lowers the vehicle’s power to avoid more harm.

At the time of approving this FSA, Ford’s Critical Concern Review Group (CCRG) and Electrical Propulsion Engineering (EPE) teams found the software updates for BECM and SOBDMC to be a suitable way to minimize the safety risks linked to power loss. The software update, by monitoring contactor resistance, warns customers if the resistance exceeds a certain limit. Alongside the warning, the software reduces power to prevent further contactor damage and the associated power loss risk. Even with the reduced power, customers can safely accelerate to highway speeds. This approach was also reviewed with the National Highway Traffic Safety Administration (NHTSA).

In June 2022, Ford Motor Company decided to issue a safety recall (NHTSA Recall 22V-412) for 48,924 model year 2021-2022 Ford Mustang Mach-E vehicles produced between May 27, 2020, and May 24, 2022. This recall was prompted by concerns about high voltage battery contactors overheating, primarily due to direct current (DC) fast-charging and repeated full-throttle pedal events. This overheating could lead to arcing or deformation of the electrical contact surfaces. If this occurs, the contactor could either remain open or get welded shut. An overheated contactor that opens while driving may lead to an immediate loss of power without re-engagement.

Following consumer complaints, the Office of Defects Investigation (ODI) initiated a Recall Query (RQ) for 2021-2022 Ford Mach-E vehicles included in Recall 22V-412. These vehicles had previously received a remedy involving a Secondary On-Board Diagnostic Control Module (SOBDMC) software update to monitor contactor temperature and reduce battery power to protect the contactor, as well as a Battery Energy Control Module (BECM) software update to monitor contactor resistance and reduce vehicle power in case of an overheated contactor.

To address this issue, dealers will replace the high voltage battery junction box. This recall is identified by Ford as 23S56, and the corresponding NHTSA campaign number is 22V-687. Vehicles included in this recall that were previously repaired under recall 22V-412 will need to have the new remedy completed.

Discovery of the Issue

Ford became aware of this issue in June 2023 when they received a report regarding thermal venting problems with the PHEV battery used in these vehicles. The report highlighted a 2021 model year Transit Custom in France experiencing PHEV battery thermal venting. Subsequent analysis, conducted by the battery cell supplier, revealed an internal short circuit in the vehicle’s high voltage battery pack, partly due to the presence of a folded anode tab, which occurred during the cell manufacturing process.

Ongoing Investigation

The supplier’s investigation indicated that another, as yet unidentified, factor is necessary for the folded anode tab condition to lead to battery thermal venting. The supplier is actively conducting component-level testing to pinpoint this second factor. While this factor remains unknown, the Ford Critical Concern Review Group (CCRG) has been working to identify the group of vehicles that may potentially have the cell folded anode tab condition.

Additional Incidents

Ford was aware of three more instances of cells with folded anode tabs in the field. These incidents involved a 2020 model year Aviator in the United States, resulting in PHEV battery thermal venting, another 2020 model year Aviator in the United States resulting in a Malfunction Indicator Light (MIL) but no battery thermal venting, and a 2020 model year Aviator in Canada, also resulting in an MIL but no battery thermal venting.

Preventive Measures

To address this issue, Ford has reviewed the cell supplier’s manufacturing process and made improvements during cell production to reduce the occurrence of the folded anode tab condition. The timing of these process enhancements has been used by the CCRG to determine the affected population of vehicles.

Recall Procedure

Owners of the affected vehicles will be notified and requested to visit their authorized Ford dealers for a Battery Energy Control Module (BECM) diagnostic test. If the test identifies a battery problem, the high voltage battery pack will be replaced at no cost to the owner.
