PACCAR issued a recall on the T660 model

On certain trucks, the retaining pins securing the hood strut tube to the hood strut assembly may become loose and fall out, allowing the lock tube to rotate on the strut assembly. In its normal operation, the safety latch feature is automatically set and prevents the hood from closing. If the retaining pins are missing, the lock tube may rotate relative to the hood strut and become a non-operational safety latch feature. A non-operational safety latch may not be detected by an operator, increasing the risk of personal injury and/or vehicle damage should the hood unexpectedly close. Correction: Dealers will replace the pivot disc and lock tube retaining pins with a revised pivot disc and cap screws.
