    That’s not good! At least you have some warranty.

    I need a truck. Boy, do I need a truck. I’m looking at a 2013 Int’l 4300 with the MaxxForce DT with the filter you apparently need to do a “regen” on occasionally, but I’ve been warned off by some while another guy says they’re fine. I need the truth. Will the emissions system give me huge expensive headaches?

    I’m considering buying a 2014 International 4300 with Maxxforce DT. It has 98,000 miles and 4500 engine hours. International has said that all of the maintenance has been done as recommended and there’s only been one minor warranty repair done. Is this one of the engines that I should avoid?

    When I spoke to International, the service manager told me that the Maxxforce DT wasn’t a problem like the Maxxforce 7. Is this true? Any advice is greatly appreciated!

    Thanks in advance!

    Did you buy this truck? Was it a problem?

    I’m considering buying a 2014 with Maxxforce DT and have the same concerns as you.

    Navistar have stopped making the MaxxForce although parts are still available. They did give up on these engines and did not make any improvements so what you see is what you get and you will pay dearly for repairs. Take it from me!

    If you Google MaxxForce class action law suits you will find a lot of that going on. A lot of fleets had major break down problems including owner operators to a point where down time crippled their operation. It has turned in to a dark time for Navistar and their MaxxForce design.

    I haven’t heard of any upgrades in 2013. This was the last year of production and nothing had changed in engineering and design.
