Ford and Navistar Settle Diesel Engine Dispute

Ford Navistar Dispute Settled
Ford and Navistar have settled a lengthy legal dispute over diesel engines.

The dispute started in January 2007 when Ford filed a lawsuit against Navistar, arguing that Navistar unjustifiably raised engine prices and had not been paying its share of repair costs for Power Stroke diesel warranty claims.

Ford said it had spent $1 billion on repairs and recalls to fix problems with legacy 6.0-liter Power Stroke diesel engines. Ford further contended that its purchase contract with Navistar allowed it to debit Navistar's invoices to recover those costs, which it had done up to $160 million after filing suit. In response, Navistar temporarily stopped shipping Ford its new 6.4-liter Power Stroke diesel engines and filed a countersuit seeking several hundred millions of dollars because Ford intended to introduce a new diesel engine that was designed by International Truck and Engine Corporation before its joint-manufacturing agreement with Navistar expired in 2011.

In a press release issued on Navistar's website, Navistar states the two companies will end their current diesel engine supply agreement effective Dec. 31, 2009. Ford will pay an unspecified amount to Navistar, but both companies will continue to collaborate on a range of other initiatives going forward.

Navistar will increase its equity stake in the truck- and parts-marking company Blue Diamond, which produces Ford-branded F-650 and F-750 medium-duty commercial trucks in Mexico. Navistar will also receive a majority stake in Blue Diamond's replacement-parts business. Both companies will continue their diesel engine supply relationship in South America.


I am almost afraid to comment here. I have owned 3 F250's with the 6.0. The 2004 blew up at 30k and was lemoned out for a 2005. The 2005 was towed multiple times to the dealer then also blew up at 31k miles. It was lemoned for a 2006. Knock on wood, the 2006 is setting a record for me. It is up to 36k with only a few minor problems.

It gets 17mpg on the highway, 14 around town with lots of stop and go and 11 pulling a 5000 pound loaded trailer.

It is a great diesel truck but I have to say, each of my trucks stickered at over $50k. The thought that I had to renegotiate each time and go through the hassle really shook my confidence in Ford products.

The new F150 seems great but I am gunshy for Ford now. The diesel is more truck than I need now and the higher fuel costs just seem like a slap in the face.

Yeah, the lower fuel economy of the fords is why I didn't buy one. (and I was afraid of the rumors of the diesel reliability being bad)

Just go with the old 5.9 Cummins in the dodge. Very reliable and I see 15 city/ 24 hwy mileage. (2wd 3500 srw shortbed).

But yeah, these days, I wouldn't buy any of the new diesels due to the new NOx regulations that are sucking the fuel economy out of the new engines (and in some cases, making them more maintenance with urea tanks).
Diesel will eventually go back up in price and then have the $1.00+ premium over 87 that it had this past summer.

The Scorpion 6.7 liter engine will be replacing the Powerstroke engine starting in 2010/2011.


The Navistar Diesels designed and built after 1993 proved to be junk with serious reliability problems. The VP of Engine Engineering was more of a politician than a engine designer, plus the relationship with Cat had gone to pot. He ended up working elsewhere in the company. McCandless was the best engine design leader at Navistar and the father of the HEUI engine.

The 6L powerstrokkes are pure D crap. I have 2 in my fleet with constant problems. My other 4 7.3 are golden even over 200,000. Not to mention to work on the 6l is a pain in the ass. Usually a 4 hour job just to change an Alternator (these are vans) and I can do the same job on a 7.3 in about 30 minutes

The 6.0L Power Stroke was a tough blow to the Power Stoke and Ford names. I reckon it did not do Navistar/International any good either.

The 6.0 diesel is the first ford truck and motor I ever regretted buying . Terrible turbo went at 20000 , sensors went , Instrument cluster went , and now fuel injectors all at under 85000 miles .

This is definitely a topic that's close to me so Im happy that you wrote about it. I'm also happy that you did the subject some justice. Not only do you know a great deal about it, you know how to present in a way that people will want to read more. Im so happy to know someone like you exists on the web.

The FICM went-out at 60K miles, the oil pressure sensor switch at the same time. It is a 2003 6.0L with 70.5K miles on it as of today, I don't drive it much. I paid over $2K to have a new FICM, oil switch, and 2 new batteries installed after this all collapsed. Did Ford ever reimburse owners with this defective engine, especially when it failed at 60K?

I had a company truck ford f450 06 6 litre and at 50 k the transmission packed it in and all the injectors in the eng had to be changed , and the last straw was exhaust gas cooler which is right in the v of the engine packed it in . The owners of my company got rid of it and bought a newer 2010 and no problems anymore. I was going to buy a ford for my personal truck but instead bought a Dodge 3500 / 07 / with a 6.7 litre and just love the truck . I have never owned a truck with so much torque and power . Its also scary fast , faster then some muscle cars i used to own .

We have 3, F-750 with 6.0 litre engines. All ran fine until around 35,000 mi. Since then we've spent close to $10K per truck with no joy. They run fine with no load. Try to carry something with them and they have no power, they belch and cough. Sometimes they have to be towed. In the vain belief that this was an issue with tank linings being eaten by fuel additives, we've replaced nearly the entire fuel systems on all three trucks -- from tanks to injectors. All for naught!!! The problem appears to lie within the International computer which controls the engines.

Ford offers no assistance whatsoever. The local Ford truck dealer loves this because each time he suggests changing something else (sometimes two fuel pumps within 12 mos.!) and collects another nice charge, but doesn't solve the problem.

I'm at a loss. For a small company, having 3 mid range trucks which are worthless to our fleet and can't be sold with integrity. What do we do?

Thanks for the comments here. Glad I saw this link. Been wondering why the 05s and 06s were going for cheap. Guess the ole addage "if it looks and smells like a rat" is true here. Heard very good things about the 7.3s tho

I have a 2005 ford f250 with only 39000 miles on it had to have towed and now sits dead ford wont do a dam thing about it all they say is their is no recalls on the triuck

I have 2006 F 250 with the 6.0 only had the egr cooler go bad at 70,000 I,m self employed and I depend on this truck for my living at this point I have 101,000 miles each run I do is 750 mile round trip at 75 mph with a load on haft the trip . I need this truck for another 100,000 miles so I,m willing to buy some more warranty becuse of everthing I here about the 6.0, Point me in the right direction please

I have a 2000 ford f250 2wd 7.3L 6speed manual with 185,184mi. Change the oil, oil filter, Fuel filter, do a injector tune up and change/add clutch fluid, and the air filter. Had to change the cloth once and a harness had come unplug due to mice moving around. Best damn diesel ford/Navistar could have made was the DT444 the 6.0l is a great diesel after you get all of the probe worked out. The 6.4L is a POS diesel, and I feel that the 6.7L could be the next 7.3L.

If that isn't unforgivable, I don't know what is. If you're going to build something, it shouldn't matter what it is, under no circumstances should you cut corners, ever.

Just got dinged for replacing the EGR Cooler and Oil Cooler on a 2004 F250 SD 6L with 80K miles on it. Not an expense I bought in for. Makes the decision to buy Ford diesel a bad one.

1996 ford f350 5spd manual best damn truck a guy could ask for 601000 miles with no major repairs ever just change oil and all filters on time. Ohhh and one camshaft sensor at 345000 miles

CTC Deezul asked where the 6.0l hate was, so I sent him a link to this page.

I only had truck 3months and have spent tousonds

I have spent tousands
