According to Ford, one GT has caught fire, in Germany. The company said no one was hurt.
The recall is for Ford GTs built between December 20, 2016, and July 31, 2018, which includes 176 examples in the U.S. and 18 in Canada. The issue, apparently, is that there's occasionally too much pressure in the hydraulic valve block below the wing, which forces fluid out. The fix uses a software update to prevent too much pressure from being applied. Some models will also be fitted with a hydraulic check valve and filter, as well as new O-rings if needed.
