Ford recalls Escape and Corsair Hybrids to fix high voltage battery issue


There are times when the manufacturing process of the car breaks down for one reason or another. For example, a wiring harness does not provide good ground contact. If you know anything about the B+ voltage, you know that you not only need a good B+ contact, but also a good B- contact, or the circuit in question won’t work.

Today’s vehicles need good ground

What circuits could it be? Any circuit that requires good contact – that is, 100% – requires good reliable contacts for things to work properly. It follows as the day follows the night. Some older car systems require the exact opposite setup. However, these systems are usually found in veteran vehicles from the last century. Every vehicle on the road today requires a good negative ground. Whether your vehicle is standard internal combustion, hybrid or all-electric, negative grounding is always the watchword.

Sometimes, however, even with the best planning and execution in the industry, it is not possible to get a good pitch for one reason or another. The reason for this may be manufacturing issues or something similar. Whatever the reason, the problem remains the same. There is no return path to the ground, so the circuit in question is not completed and the vehicle breaks down.

This is the case for some 2020 Ford Escape and 2021 Lincoln Corsair models equipped with hybrid powertrains. Specifically, Ford recalled 27 SUVs equipped with 2.5-liter hybrid powertrains.

The vehicles in question have insufficient solder in their high voltage batteries, so those batteries can fail – not a good thing in a hybrid as it could leave them powerless. In the event of a loss of engine power, the vehicle would stop, creating the risk of an accident. However, according to documents filed with the National Highway Traffic Safety Administration (NHTSA), none occurred.

Consumer Information Discussed

Ford will begin notifying owners of affected vehicles on July 5, 2022. At that time, owners will be able to schedule service appointments with their dealerships. Dealer technicians will examine and replace the high voltage battery free of charge.

For more information, owners can contact Ford Customer Service at 866-435-7332. The Ford ID on this is 22S33. Or, owners can contact NHTSA’s Vehicle Safety Hotline at 888-327-4236 or visit the agency’s website at The NHTSA identifier is 22V331.

Marc Stern has been an automotive writer since 1971, when an otherwise normal news editor said, “You’re our new car editor,” and threw about 27 books of automotive stuff on my desk. I was in heaven because I had been a reducer since my debut. As a teenager, I spent the usual amount of unnecessary hours hanging around Shell and Texaco gas stations (a big thing in my youth) and working on cars. From there it was a straight line to my first column for the newspaper, “You Auto Know”, a business I ran faithfully for 32 years. Few people know that I also managed IT documentation for a good part of my life writing YAN. My best writing, however, has always been in cars. My work has been published in Popular Mechanics, Mechanix Illustrated, AutoWeek, SuperStock, Trailer Life, Old Cars Weekly, Special Interest Autos, etc. You can follow me on: Twitter or Facebook.
