2013–2017 International 4400 Recall

On certain fire trucks, the retaining ring(s) in the relief valve assembly may not have been made using high grade stainless steel, causing it to deteriorate over time due to frequent exposure to water. If the retaining ring fails, the relief valve may break down and prevent the fire pump from building adequate pressure, which would increase the risk of injury during firefighting operations. Correction: Dealers or certified technicians will inspect and replace the retaining ring(s) as necessary.
