Last week, Ford filed a lawsuit against Navistar, the maker of the Power Stroke diesel engines offered in the Super Duty pickups. The suit alleges non-compliance with warranty cost-sharing and "unjustifiably" raising prices on the new 6.4 Power Stroke offered in the '08 Super Duty models.
The suit also alleges that Navistar has threatened to cut off Ford's supply of engines if Ford does not pay the price the company is demanding.
Diesel Power's Take: Ford still has a bitter taste in its mouth from the headaches it had with the troublesome 6.0 Power Stroke. Considering its financial situation, it's not surprising it's trying to re-coup some of the costs it incurred with that engine. Considering the drama between these two companies over the past few years, it's not far-fetched that Ford may be seeking a new vendor for its diesel engines. With Cummins contractually obligated to Dodge, at least for a while longer, the next most logical candidate would be Caterpillar. How will this all play out? It's anybody's guess.
