Paccar mx 13 camshaft problems

Paccar mx 13 camshaft problems DEFAULT

The complaint for this class action claims that PACCAR engines are inherently defective and repeatedly fail, causing danger to the drivers of its trucks and to other motorists on the road. According to the complaint, the only remedy PACCAR has for its engine problems is the replacement of defective parts with equally defective parts that are destined to fail in their turn.

The Nationwide Class for this action is all individuals or entities in the US, except in New Jersey and Texas, who leased or bought the vehicles at issue, not for resale. In the alternative, the complaint proposes statewide classes for California, Florida, and Wisconsin.

PACCAR, Inc. makes medium- and heavy-duty trucks and sells tractor-trailer and vocational trucks in the US. Its truck-making subsidiaries are Kenworth and Peterbilt. Originally, the company bought the diesel engines for its Class 8 vehicles (those with a weight rating of over 33, pounds) from other companies, such as Caterpillar.

Beginning in , the complaint says, the company began to build its own engines via its subsidiary PACCAR Engine Company. The PACCAR MX engine was somewhat based on a PACCAR engine that had already been used for years, and according to the complaint, the company touts it as being reliable, economical, and effective. The complaint says the engine is in use in many Peterbilt trucks and in over 35 percent of Kenworth trucks.

However, according to the complaint, the engine has inherent defects. These cause the appearance of fault codes to warn the driver that the vehicle requires servicing, leading to excessive downtime.  Worse, the defects may cause the trucks to lose power and stop, creating a danger on the road and extra expenses for the vehicles’ owners in the need for towing to a PACCAR-authorized repair shop. The complaint asserts that the faulty engines also lower the trucks’ resale value.

The complaint claims that PACCAR and its subsidiaries are fully aware of the engines’ defects because of the increase in warranty repairs after the engines went into use. Unfortunately, the complaint says, the repairs performed on the engines do not solve the inherent problems with the engine; defective components are simply replaced with other defective components that will fail in their turn. Truck owners can get these repairs for free while the vehicle is under warranty, but since the defects still exist even after repairs are performed, the complaint claims that the time and damage limits of the warranties are unconscionable.

The complaint alleges breaches of warranties, among other things.

Thanks for the feed back. Looks like I will keep looking. After treatment system and emissions really concern me with the short hauls we do.



The Cummins and MX use identical aftertreament systems. Any issues the MX has, the ISX can have in that dept.

MX also uses a Cummins Turbo, if it sucks blame Cummins but we already knew that thanks to the ISX's love for turbos ;)

The MX has had issues, + are better. The ISX certainly has not been the pinnacle of reliability either during this time. Newer ISX (CM) are better as well.

The MX is a European engine(DAF), it's also a pushrod engine. Two things that worked against them when they had cam issues, rear gear train is popular in Euro engines and the MX is rear gear train also which means pulling the engine to swap a cam. Rear gear train is quiet and smooth though. Some don't like working on or servicing euro engines, but it's not that foreign IMO. There's a metric crapload of room under the hood of a conventional KW or Pete with the MX, makes it nice to work on.

I had a plane ticket bought to buy an ISX KW, one popped up local with an MX and I decided on that instead. I was a bit worried due to all the doom and gloom, but knew the newer ones were better. It has been phenomenal, nice to drive, smooth and sips fuel. Drives like the C13 we had, all low end done at rpm type driving.

The ISX issues are downplayed/ignored by many because it's a Cummins. But if one of the in-house engines breaks, holy hell its a giant POS. Every engine went through a rough time the past 10 years, they've all stepped up and come out with some improved engines now. The MX is over many issues, the Merc/DD has improved, even the Maxxturd has actually improved into the N13 which is phenomenal so far but can't shake its reputation, and of course the all mighty ISX has fixed some of its issues as well.

Keep in mind too a lot of these issues were certain groups of engines. The ISX's that drank a gallon of oil every couple days, the MXs with over hardened cams, the ISX's with cam issues, etc.


Whatever you buy, it will either be the biggest POS or the greatest thing ever depending on who you talk to. If everyone keeps saying the MX is junk then great, makes them cheaper for the rest!

  1. When there was a recall on the camshafts a couple years ago they would pay 25hrs to remove the engine, strip down the behousing and geartrain, strip down lh side of engine to access the lifter bolts, strip down the top and preform a top set, r+r camshaft and lifter, reassemble everything and drop it back in the truck. I did one in 21 hrs just to prove i could but more common was 30 hrs or so to change out a camshaft.
    Swapped the cams on 12 or so trucks during that recall. Only had 1 that had a failure and needed extra parts. All other cams i removed looked perfect.
    Have not seen a cam failure outside of that recall yet.

  3. We had one fall under that campaign. Warranty must of not paid for EUP holdown bolts cause they sheared off two months later on rear pump and made quite a mess and tow bill! Warranty did cover parts and labor on 2nd repair. I can&#;t complain about warranty coverage and Paccar taking care of MX issues.
  4. Bore for lifter was scratched/scored, but I was told it cleaned up fine with a hone. Doesn&#;t seem to be a common issue like like Mack Etech Cam rollers or rollers in Cummins ISX fuel pumps. Crappy part is if cam has to come out, engine has to come out.
    Was it intake or exhaust valve that broke?
  5. Was #3 hole intake lifter that failed. Driver was blowing off his load of cement and noticed a vibration. Thought it was just a u-joint in blower shaft going out. When he was done and kicked out PTO realized it was in the engine. Call dispatch(2 A.M.) and of course first instinct was to try to get other load if possible. Nowadays, if check engine light ain&#;t on then there is no problem. He took off and realized had a dead miss so brought back to shop, but was 7 miles from dealer and 50 miles from shop. I checked it out when I got in. Fired it up and I shut it off immediately. Had fault codes for #3 misfire/torque contribution. Sounded to me like dropped valve or lifter (been around Mack ETechs so I know the sound). Had towed to dealer. They ran it and said yes has a miss, but they are slammed and will be a week. Pulled valve cover and discovered bent push tube. Pulled head and inspected valves and piston. No visible damage and valves not bent. Engine is out, new cam and lifters installed, and buttoning motor back together. They should swing engine back in Monday.
  6. Thank you for the help.
    I still find it interesting that the 13mx is a pushrod engine in this day of overhead cam being the normal thing.
    I agree, Just as the Corvette STILL uses the "antiquated pushrod" dinosaur yet look at it&#;s performance, reliability, efficency, and maintenance!! all outstanding!!
  7. I will say, I love my MX13
    I now have k on mine and aside from normal maintenance, has given me no problem. I am considering uncorking it but none of the emissions have given me any problems. Just hoping to get better mileage after removing the cork. Gets around mpg. I feel it could be better. I haul motorcycles so my average payload is less than 30k lbs. But am hauling with a double decker trailer which adds weight. From what I hear from the dealer, the most important thing on these engine is running the rack. If the cam somehow get damaged from not doing it, it cost big time. The motor has to be pulled cause the cam comes from the rear of the engine.

    4 Signs of Bad Camshaft failure symptoms makes noise and cause misfire how it works explanations

    Pete KenworthPaccar Inc., who manufactures Kenworth and Peterbilt trucks, has notified the National Highway Traffic Safety Administration of several recalls, which were issued last week.

    The following are three recalls issued by PACCAR last week:

    •Paccar says during assembly, certain Kenworth models did not undergo the rear wheel mounting torque verification process, which could result in the rear wheels being loose and separating from the truck.

    Certain Kenworth T, T, T and W trucks manufactured between Feb. 1, , and April 20, , are included in this recall. Paccar estimates 49 trucks to be affected in this recall.

    Kenworth will notify owners, and dealers will verify the rear wheel lug nuts are correctly tightened, free of charge. A notification schedule has not yet been released.

    •More than , Kenworth trucks are included in a recall in which water may leak into the windshield wiper motor, possibly causing the wipers to stop working on the “intermittent” setting, reducing the driver’s visibility. The water may also cause corrosion which, over time, could result in an electrical short.

    Model year Kenworth , T, T, T, T, C, C, C, T, T and W models manufactured from Nov. 1, , to April 7, , are affected by the recall.

    Paccar is still developing and testing a remedy, according to the recall notice.

    •Approximately 1, trucks are included in a recall in which trucks equipped with the Paccar MX engines and Delco-Remy 40SI alternators have alternator charge cables that may chafe against a formed metal freon discharge line, which could cause an electrical short resulting in a fire.

    Included in the recall are Kenworth T, T, T trucks manufactured from Feb. 18, to April 10, , and Peterbilt , , , and trucks manufactured from Dec. 13, , to April 20,

    Paccar will notify owners, and dealers will reroute the alternator cable away from the metal freon line, free of charge.
