Some 2020 Mustang GT500 vehicles may exhibit a difficulty opening or closing the hood. This may be due to the hood pin assemblies sticking in place. To correct this condition, open the hood, depress both buttons on both pins so that they remain in the depressed position. Use a shop rag to apply a light coating of Motorcraft XL\-10 or equivalent to both of the hood pin assemblies on the inside of the depressed area of the pins where the release button is located. Open and close the hood several times to help the XL\-10 to penetrate them. Wipe away any excess XL\-10 from all surfaces around the pins. For claiming, use causal part 16A770.
