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.

Chevy Bolt Battery Problem Update

Posted on by

General Motors is still rolling out new batteries for the troubled Chevy Bolt electric vehicle, albeit very slowly. We are hearing from clients and potential clients that dealerships are putting them on “wait lists” for the new battery but are not hearing again from the dealership. The dealerships give the owner no times table for getting their new battery as well. Obviously, this is very frustrating for consumers who are tired of figuring out ways to safely charge their EV. To date, we have only heard of the new batteries actually being installed in the 2017 – 2019 year models, but not for any 2020-2021 models. The good news is that once the battery has been installed, consumers seem to be happy with the new battery giving them a longer range than the original. More importantly, we have not heard of any problems associated with the new battery. This is good news for consumers.

With that said, we are still accepting Chevy Bolt cases, regardless of whether the new battery has been installed, and we continue to achieve favorable settlements with General Motors. Many of our settlements are for cash, allowing the consumer to receive compensation while being allowed to keep the vehicle.

Please call us at 1-888-395-3666 for more details about this problem.

Chevrolet Bolt EV

Here is a summary of the defect.
General Motors recalled all of their Chevrolet Bolt EVs because there is a manufacturing defect affecting the battery cell. The problem is aggravated when the battery is charged to a full or nearly full state after it has been substantially depleted. The battery could overheat and catch fire, causing damage to the vehicle and structures around it. As a temporary solution, GM asked owners to reprogram their hybrid propulsion control module to limit a full charge.

The safety recall from the NHTSA states the following:
As an interim remedy, dealers will reprogram the hybrid propulsion control module to limit full charge to 90%. Until this interim is completed, customers should enable either “Hilltop Reserve” (for 2017-2018 model year vehicles) or “Target Charge Level” (for 2019 model year vehicles) using their vehicle’s infotainment center. These two features will limit the vehicle’s state of charge to 90% until the HPCM2 software re-calibration is applied. If customers are unable to successfully make these changes or do not feel comfortable making these changes, they will be advised to not park their car in their garage or carport until after they have visited their dealer.
