2007 Peterbilt 320 Problems, Complaints & Recalls

Problem: PACCAR Incorporated (PACCAR) is recalling certain 1990-2020 Peterbilt 320 and 520 vehicles built with specific amber rear turn signals. The turn signals may also light up with the stop/tail lights when the brakes are applied. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: Rear Turn signals that illuminate at the same time as the brake lights may create confusion and impair the effectiveness of the brake lights, increasing the risk of a crash.

Fix: PACCAR will notify owners, and for trucks with rear amber lights, dealers will add a jumper harness between the chassis electrical harness and amber tail lights, free of charge. The recall began August 1, 2019. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's number for this recall is 19PBC.

Problem: Certain trucks equipped with bendix sr-7 spring brake modulating valves. The internal rubber check valve may leak causing a delay in the application of the spring brakes to park the vehicle after the operator pulls the dash valve button.

Risk: This could delay or failure in applying the parking brakes potentially resulting in a vehicle roll away.

Fix: Dealers will install a check valve repair kit for the affected sr-7 spring brake modulating valve free of charge. The recall began on august 22, 2007. Owners may contact peterbilt at 940-591-4201.

Problem: On certain trucks, the axle housings may have been manufactured with steel that was out of specification which could result in a fatigue failure over time.

Risk: If a fatigue failure occurs and is left unattended, the axle may lock up or the end of the axle could come off, which may result in a vehicle crash.

Fix: Dealers will inspect and replace the axles free of charge. The recall began on may 9, 2007. Owners may contact kenworth at 425-828-5440 and peterbilt at 1-940-591-4196.
