Ford recalls 18 F-150 Lightnings over battery issue

Ford Motor Co. said Friday that it is recalling 18 F-150 Lightning pickup trucks due to a battery cell manufacturing defect.

The recall follows a five-week production shutdown at the Rouge Electric Vehicle Center in Dearborn where the electric truck is made. The automaker said Friday that production is slated to resume Monday as previously planned.

The company said in a statement that the manufacturing defect at supplier SK On’s plant in Georgia occurred over a four-week span starting at the end of last year. Initially, the automaker said it believed the defect was not present in any Lightning units that had been delivered to customers or dealers, but it now has identified 18 such units that are affected.

Ford has said that the issue initially came to light Feb. 4, when a vehicle displayed a battery issue during a pre-delivery quality check and then caught fire while it was parked in a holding lot near the plant. The fire spread to two other Lightning units. That incident prompted the five-week production shutdown and a halt on shipments while Ford and SK On investigated the underlying issue.

The two companies later said the root cause had been identified in SK On’s battery cell production process, and that a fix had been implemented.

“Working with Ford, SK On identified the root cause of the issue and implemented measures of improvement in our processes to address the issue,” SK On said in a previous statement. “SK On believes this was a rare occurrence, not a fundamental issue with the technology of the battery cells or the overall manufacturing systems.”

Asked Friday about the nature of the defect, Ford said the recalled units’ high-voltage batteries can experience a short that could result in a vehicle fire when they are at a high state of charge.
