Peterbilt 340 — MPG, VIN Decoder, Recalls, Reliability & Specs

What's wrong. Peterbilt is recalling certain model year 2010 and 2011 model 325, 330, 335, 337, 340, and 348 trucks. The hood anti-blowdown device is designed to prevent unintended and unexpected hood closure. The device within can become hindered or inoperative due to unintentional latch movement which interferes with the hood pivot j-hook, latch misalignment, or latch fallout.

Risk. An unintended latch closure can cause personal injury.

Fix. Dealers will install hood anti-blowdown retention cables to the radiator and hood assemblies free of charge. The safety recall began on june 21, 2010. Owners may contact perterbilt at 940-591-4196.

What's wrong. Paccar is recalling model year 2008-2010 kenworth t300, t270, and t370, model year 2009-2010 t800 and peterbilt model year 2008-2010 335, 340, and 367 vehicles built on cummins' diesel engine. The vehicles may be designed with a hard wired, dash-mounted switch that enables the vehicle operator to inhibit aftertreatment diesel particulate filter regeneration in environments where the operator believes it may be unsafe for elevated exhaust temperatures. Due to an issue with the logic in the ecm software in these engines, the switch may not function correctly, leading the operator to believe that the switch is in "inhibit" mode when it is not.

Risk. This condition will permit hot exhaust gases to exit the vehicle tailpipe, increasing the risk of melting or burning of nearby surfaces, or a fire.

Fix. Paccar is working with cummins to repair the engines free of charge please see 09e-046. The safety recall began on october 1, 2009. Owners may contact cummins at 1-800-diesels (1-800-343-7357).

What's wrong. PACCAR Incorporated (PACCAR) is recalling certain model year 2009-2010 Peterbilt 340, 2010, 2012, and 2015-2016 Peterbilt 337, 2010 Peterbilt 335, 2011-2016 Peterbilt 348, 2009 and 2011-2016 Peterbilt 365, 2009 and 2012-2013 Peterbilt 386, 2009-2015 Peterbilt 388, 2015-2016 Peterbilt 389, and 2015 Peterbilt 567 auto hauler vehicles. The affected trucks are equipped with Michelin 295/60R22.5 XZA-2 front tires that have a speed rating less than the vehicle is governed to.

Risk. Higher vehicle speeds and other factors such as tire load and road temperatures may result in premature tire failure, increasing the risk of a crash.

Fix. Peterbilt will notify owners, and dealers will reprogram the engine's vehicle speed parameters to limit the maximum vehicle speed to the tire speed rating, free of charge. The recall began on January 4, 2016. Owners may contact Peterbilt customer service at 1-940-591-4000. PACCAR's number for this recall is 1115P.

What's wrong. PACCAR Incorporated (PACCAR) is recalling certain 2008-2019 Peterbilt 330, 335, 337, 340, 348, 365, 367, 384, 386, 387, 388, 389, 567, 579 and 587 vehicles and 2008-2020 Kenworth T170, T270, T370, T660, T680, T800, T880, and W900 vehicles equipped with NAMUX Software. In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems," and 136, "Electronic Stability Control System on Heavy Vehicles."

Risk. If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.

Fix. PACCAR will notify owners, and dealers will update the NAMUX software within the cab control module, free of charge. PACCAR issued owners an interim notification on June 4, 2020. The recall began May 26, 2020. Owners may contact Kenworth customer service at 1-425-828-5888 or Peterbilt customer service at 1-940-591-4220. PACCAR's number for this recall is 20pbc AND 20KWB.

What's wrong. Paccar is recalling 1,043 my 2008-2009 kenworth c500, t2000,t660, t800 and w900 trucks equipped with bendix mv-3 dash control valves. The molded valve body has an incorrect core pin in the injection mold causing the valve body to be oversized in the double check valve area. This condition can allow the rubber double check valve to become lodged in the body opening under certain circumstances.

Risk. If the double check valve becomes lodged, in the event of a primary reservoir failure, air pressure can leak past the lodged double check valve thereby depleting the secondary reservoir, causing reduced ability for modulating the service emergency brakes. In such an event, the operator should observe an air leak, indications of low air pressure via the primary and secondary air gauges, and audible and visual low air pressure warning alarms. A vehicle crash is possible if these warnings are not heeded.

Fix. Dealers will replace the bendix mv-3 dash control valves free of charge. The recall began on april 14, 2008. Owners may contact kenworth at 1-425-828-4196.

What's wrong. Certain trucks equipped with bendix sr-7 spring brake modulating valves. The internal rubber check valve may leak causing a delay in the application of the spring brakes to park the vehicle after the operator pulls the dash valve button.

Risk. This could delay or failure in applying the parking brakes potentially resulting in a vehicle roll away.

Fix. Dealers will install a check valve repair kit for the affected sr-7 spring brake modulating valve free of charge. The recall began on august 22, 2007. Owners may contact peterbilt at 940-591-4201.

What's wrong. On certain medium duty vehicles, the right side stabilizing rod, which spans the cooling module and the right frame rail bracket, was inadvertently designed too close in proximity to the alternator positive electrical terminal post. In the event the protective rubber boot on the terminal post was removed or cracked and the engine mounts allowed the engine to rock, electrical arcing could occur between the radiator tie rod hardware on the frame side and the alternator terminal post while the engine is running.

Risk. The electrical arcing could potentially ignite a fire in the engine compartment.

Fix. Dealers will replace the right radiator tie rod and corresponding mounting bracket with a longer radiator tie and different mounting bracket which will adequately space apart the tie rod mounting hardware and mounting bracket free of charge. The recall began on august 22, 2007. Owners may contact peterbilt at 940-591-4201.

What's wrong. Certain trucks equipped with eaton synflex eclipse brand extruded nylon air brake hose tubing fail to comply with the requirements of federal motor vehicle safety standard no. 106, "brake hoses." the tubing was manufactured with only four layers of nylon material, instead of the specified five layers.

Risk. The diameter of the hose affects the fittings which may allow air to leak from the brakes and create the potential for a vehicle crash.

Fix. Dealers will inspect the air brake hoses and, if necessary, replace the hoses. The recall began on february 22, 2008. Owner notification schedule for this campaign. Owners may contact kenworth at 1-425-828-5440 or peterbilt at 1-940-591-4196.
