Ford Motor is recalling 634,000 sport utility vehicles (SUVs) worldwide over fire risks from possible cracked fuel injectors and will urge owners to have their cars inspected, it said on Thursday.
America's No.2 automaker by sales said the recall covers 2020-2023 model year Bronco Sport and Escape SUVs with 3 cylinder, 1.5 litre engines, including many also recalled in April because an oil separator housing could crack and develop a leak that could cause an engine fire. Vehicles repaired under the earlier recall will still need the new recall fix, the National Highway Traffic Safety Administration said.
Ford said when engines in the SUVs covered by the latest recall are operating, a cracked fuel injector could cause fuel or fuel vapour to accumulate near hot surfaces, potentially resulting in fire under the hood, reports Reuters.
Once repairs are available dealers will update the vehicle software to detect whether a fuel injector is cracked and provide a dashboard message to alert drivers.
"If a pressure drop in the fuel rail is detected, engine power will automatically be reduced to minimise any risk, while also allowing customers to drive to a safe location and stop the vehicle and arrange for service," Ford added.
Dealers will also install a tube draining fuel from the cylinder head and away from hot surfaces and check for excessive fuel odour near the top of the engine.
The recall covers about 520,000 vehicles in the United States and about 114,000 in other countries.
Ford said it has 54 total reports of 1.5 litre under-hood fires, including four with cracked fuel injectors. About 13 others were probably caused by a leaking fuel injector.
There are no deaths linked to the recall.
Ford said it is not telling owners to stop driving vehicles under this recall. The company projects a low failure rate for fuel injectors experiencing external leaks.
