Ford finds fix for under-hood fires, expands recall on 2021 Expedition, Lincoln Navigator

Ford Motor Co., hit with a lawsuit last month by owners of the 2021 Expedition and 2021 Lincoln Navigator angry about an unfixable fire recall, announced Friday that the company has figured out the problem and the solution.

At the same time, the company expanded its recall from 39,013 to just over 66,000 SUVs based on its analysis of the problem.

Ford has not asked customers to stop driving the vehicles, telling  regulators it is not aware of any accidents caused by the faulty parts.  

However, drivers of these premium vehicles with a base price that exceeds $50,000 are still being advised to park outdoors and away from structures until the repair is made. Vehicles may pose a risk of under-hood fire, including while the vehicle is parked and off.

Ford has received 21 reports of under-hood fires — including five since the original recall filing in May — with 18 incidents impacting vehicles owned by rental companies. Ford is aware of one reported burn injury, according to documents filed with the National Highway Transportation Safety Administration (NHTSA).

Two-thirds, or an estimated 44,000 owners, won’t be able to get the repair until September because of parts delivery challenges, Ford said. . 

The Dearborn automaker said in a news release that the company traced the cause of the vehicle fire problems to a change in manufacturing location by a supplier during the COVID-19 pandemic.

‘High-current short’

“Printed circuit boards produced at this facility are uniquely susceptible to a high-current short and were supplied to Ford and installed in Expedition and Navigator SUVs produced” between July 27, 2020, and Aug. 31, 2021, the release said.

Ford dealers have sent a repair protocol to its dealers, who are “working quickly” to make parts available as soon as possible, Ford said in the release. 

First, dealers will inspect the battery junction box for melting damage, and if it’s observed, will replace the entire component. Then the repair team will remove the engine fan ground wire from the battery junction box in affected vehicles with an 800-watt cooling fan system, which represents about one-third of the recalled vehicle population, Ford said.

“This repair can be done immediately,” Ford said.

For the remaining affected vehicles with a 700-watt cooling fan system, the repair is the same, except for the installation of an auxiliary box with a wire jumper, Ford said. Parts for this repair are scheduled for delivery in early September.

Ford was to notify affected customers by Friday, with follow-up communication to customers of vehicles with 700-watt systems when parts are available. 

Supplier problems

In June, John McElroy, longtime industry analyst and host of the “Autoline After Hours” podcast and webcast, questioned whether a significant number of recall and warranty issues might be blamed on a breakdown in communication between Ford and its suppliers.
