Federal regulators are investigating Ford Motor Co.'s recall of nearly 49,000 Ford Mustang Mach-E vehicles that took place last year. The National Highway Traffic Safety Administration (NHTSA) has opened an investigation into how Ford handled the recall after receiving 12 complaints from owners who said their vehicles were recalled and fixed, but they still experienced problems with the battery.

The reason for the recall was identified as a potential issue with the high voltage battery main contactors overheating from charging and other use, which could lead to damage and an increased risk of power loss or crashes. Ford issued the recall in June 2022 for Mach-Es produced between May 27, 2020, and May 24, 2022.

The NHTSA now estimates that around 65,000 vehicles could be affected by the issue. Ford has not yet commented on the investigation.

It remains to be seen how this investigation will impact the safety and reliability of Ford Mustang Mach-E vehicles. Owners and potential buyers should stay informed about any updates from Ford or the NHTSA regarding the recall and the ongoing investigation.
