2019-2024 Jaguar I-Pace Battery Could Overheat

Posted on by

Certain 2019-2024 Jaguar I-PACE SUV electric vehicles are facing a critical issue that could pose a potential threat of vehicle fires due to excessive heat buildup inside the high-voltage battery. The Jaguar Product Safety and Compliance Committee (PSCC) identified this problem in February 2022 through the Jaguar Land Rover (JLR) critical concerns reporting process. As a result, Jaguar initiated a thorough investigation into the matter.

To address the issue, Jaguar collected the batteries from the affected vehicles and conducted meticulous inspections at their testing facilities. Subsequently, the batteries were sent back to the supplier for further and more detailed analysis. In addition, Jaguar acquired Diagnostic Over The Air (DOTA) data for comprehensive examination and evaluation.

According to the defect report, specific 2019-2024 Jaguar I-PACE SUV electric vehicles have experienced instances of thermal overload, which can manifest as smoke or fire. The overheating primarily occurs beneath the vehicle, where the high-voltage traction battery is located. While investigations are still ongoing, Jaguar has proactively decided to install software that will effectively monitor the battery’s status.

Owners of the affected vehicles will receive notifications regarding the issue. They can visit a dealer or opt for an over-the-air (OTA) update to have the battery energy control module software updated. This updated software will continuously monitor the operational status of the battery pack assembly, identifying conditions that may lead to a thermal overload. In order to ensure safety, the software will provide enhanced driver warnings regarding the battery’s condition. When a risk is detected, the charging capacity of the High Voltage battery will be limited to 75%. A warning message will alert the driver, accompanied by instructions in the Owner Guide, which will direct them to take their vehicle to a Jaguar retailer for diagnosis and, if necessary, repair. The retailer will conduct a thorough inspection and, if required, replace the affected battery module or pack.

Jaguar has assigned the identification number H441 to this recall, while the NHTSA campaign number is 23V-369.

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.

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.

2021-2022 Ford Mustang Mach E High Voltage Battery Could Overheat

Posted on by

Ford will be contacting the owners of certain 2021-2022 Mustang Mach E vehicles because the high voltage battery in their cars may overheat. The problem may lead to loss of power and could increase the chance of an accident.

Ford’s Critical Concern Review Group first became aware of the problem in April 2022, after hearing of an issue pertaining to the high voltage battery main contactor overheating in a Mustang Mach E. A review of warranty reports found approximately 286 warranty claims where the problem was an open or welded battery contactor. According to the defect report, it is possible that the high voltage battery main contactors may overheat, which can result in an open contactor or a welded condition.

Contactors that are welded shut while driving, will result in an illuminated powertrain malfunction warning light on the next drive cycle, along with a no-start condition.

Contactors that become open while driving, will result in a powertrain malfunction warning light, the vehicle will display “Stop Safely Now” on the instrument panel, and the vehicle will lose power.

In both cases, all 12V systems including power brakes and steering will remain functional.

Ford will correct the problem by installing a Secondary On-Board Diagnostic Control Module (SOBDMC) and updating the Battery Energy Control Module (BECM) software. Ford is expected to begin Over-The-Air (OTA) updates for the SOBDMC and BECM software in July 2022. Owners will also have the option to take their vehicle to a Ford or Lincoln dealer to have the software update completed.

The updated SOBDMC software (LJ98-14G069-AXG, LJ98-14G069-AZG, LJ98-14G069-BBG, LJ98-14G069-BDG) will monitor contactor temperature and intelligently reduce battery power to prevent damage to the contactor. The updated BECM software (NJ98-14C197-AE, NJ98-14C197-BD) will monitor contactor resistance to identify an overheated contactor and reduce vehicle power to prevent further damage.

Ford’s number for this recall is 22S41 and the NHTSA campaign number is 22V-412.
