Trucking companies across the nation have filed a flurry of class action lawsuits against Navistar International Corp over what the claim are faulty engines. The lawsuits allege that the MaxxForce engines that Navistar manufactured and sold between 2008 and 2013 are defective.
The lawsuits allege that the defects in the engine lead to repeated failures that cost the owner of the truck thousands of dollars in repairs and downtime. At the root of the problem is Navistar's reliance on exhaust gas recirculation to try to meet federal emissions standards causing the engines to overheat and produce soot inside the engines at a rate much greater than normal. Navistar was the only major North America engine manufacturer that did not use selective catalytic reduction aftertreatment systems to meet 2010 emissions standards.
The lawsuits also allege that the defective engines were prone to sudden breakdowns that forced drivers to quickly pull to the side of the road – a particularly risky proposition when carry heavy cargo on an 18-wheeler.
Additionally, the lawsuits allege that when the engines were brought for repairs that were covered by the warranty, Navistar simply replaced the faulty emission system with another equally defective system rather than repair the initial one.
The plaintiffs' primary complaint is the excessive downtime caused by the engine problems that resulted in loss of revenue. Additionally, the trucks have lower trade-in value due to the problems with the engines.
Some of the trucking companies that have filed suit include:
- Tango Transport
- Par 4 Transport
- Dennis Gray Trucking
- Carmichael Leasing
- GTL Enterprises
- Americorp Xpress Carriers
- First Express
- Floyd Blinsky Trucking
Navistar filed a motion with the court to have the lawsuits dismissed. That motion was denied on August 18.
