12 recalls found in NHTSA data as of September 22, 2026

For the 2007 Mack CHN. These apply to the model and year, not to one particular vehicle: check your VIN to see whether yours is included and whether it has been repaired.

Has your Mack been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Mack dealer can also check your VIN. Recall repairs are free.

2007 Mack CHN recalls, newest first

October 23, 2007NHTSA 07V497000950 vehicles potentially affected

Trailer hitches › Fifth wheel assembly

Summary
On certain trucks equipped with a saf holland simplex fifth wheel, the lever arm pivot bolt may have been over tightened. An over tightened pivot bolt can distort the pivot bolt spacer sleeve, which may prevent the fifth wheel latch jaw from closing and latching securely around the trailer king pin.
Consequence
There is a possibility that the pivot bolt can become loose without the driver's knowledge. When this occurs, the driver could drive away and the trailer could become disengaged, increasing the risk of a crash.
Remedy
Dealers will replace the pivot bolt and sleeve with a hex head shoulder bolt and washer free of charge. The recall began on January 28, 2008. Owners may contact mack trucks at 1-800-528-6586.

September 5, 2007NHTSA 07V40100035,649 vehicles potentially affected

Fuel system, diesel

Summary
On certain trucks equipped with aset AC model engines, the engine as configured with an external exhaust gas recirculation system makes servicing the fuel injection lines difficult when using traditional tools. Therefore, it is possible for fuel leaks to develop when removing and installing the fuel injection lines.
Consequence
A leak in the fuel injection line may spray fuel on the hot surfaces of the exhaust gas recirculation system, which could result in an engine fire.
Remedy
Dealers will replace the fuel injection lines free of charge. Note: this recall supersedes a previous campaign conducted in 2006 (please see 06V392). The recall began on September 11, 2007, with subsequent mailings every six weeks until April 2008. Owners may contact mack at 800-528-6586.

August 15, 2007NHTSA 07V36100021,847 vehicles potentially affected

Service brakes, air › Supply › Check valve

Summary
On certain trucks equipped with parker single check valves (scv) provided by bendix. The defect exists in the parker scv that connects with the supply port of the SR-7 spring brake modulating valve. After prolonged use of the parker scv, the valve body retainer may become excessively worn and eventually break apart. Pieces of the parker scv can become lodged inside the SR-7 spring brake modulating valve, potentially causing either leakage out of the SR-7 valve or preventing air from properly exhausting from the SR-7 valve.
Consequence
This condition can cause a delay in the application of the spring brakes to park the vehicle after the operator pulls the dash valve button. These conditions can occur without warning, leading to unintended vehicle rollaway, brake drag, or in the case of loss of primary circuit, inability to modulate the spring brakes.
Remedy
Mack is working with bendix to replace the parker single check valve. The recall began on January 9, 2008. Owners may contact bendix at 1-440-329-9000 or mack at 1-800-528-6586.

Remedy
Mack is working with bendix to repair these vehicles (please see 07E037). Bendix will install a check valve repair kit for the affected SR-7 spring brake modulating valve free of charge. The recall began on January 10, 2008. Owners may contact bendix at 1-440-329-9000 or mack at 1-800-528-6586.
