Ford Motor Co is recalling 634,000 SUVs worldwide due to fire hazards from possible burst fuel injectors and urging owners to have their cars inspected.
The No. 2 automaker in the US said the recall affected model year 2020-2023 Bronco Sport and Escape four-wheel drive with three-cylinder 1.5-liter engines.
They also included many who were recalled in April because an oil separator housing could burst and develop a leak that could cause an engine fire.
Vehicles repaired under the earlier call still require the new recall, the U.S. National Highway Traffic Safety Administration said.
Ford said when engines in the 4WDs subject to the latest recall were running, a cracked fuel injector could cause fuel or fuel vapor to build up near hot surfaces, potentially resulting in an under-hood fire.
Once repairs become available, dealers will update vehicle software to detect if a fuel injector has cracked and send a dashboard message to warn drivers.
“If a pressure drop in the fuel rail is detected, engine power is automatically reduced to minimize any risk, while customers can also drive to a safe location, stop the vehicle and schedule service,” said Ford.
Dealers will also install a tube that drains fuel from the cylinder head and away from hot surfaces, and check for excessive fuel odor near the top of the engine.
The recall affects approximately 520,000 vehicles in the US and approximately 114,000 in other countries.
Ford said it had a total of 54 reports of 1.5 liter fires under the hood, including four involving burst fuel injectors.
About 13 others were probably caused by a leaking fuel injector.
There are no deaths associated with the recall.
Ford said it was not telling owners to stop driving vehicles under this recall.
The company predicted a low failure rate for fuel injectors with external leaks.
