Paccar Inc., who manufactures Kenworth and Peterbilt trucks, has notified the National Highway Traffic Safety Administration of several recalls, which were issued last week.
In total, three recalls were issued, but the biggest recall was on 11 different models of newer Kenworth trucks. The recall was issued because water could leak into the windshield wiper motor, causing wipers to fail when they are on the intermittent setting. If left unchecked, the corrosion could lead to an electrical shortage. The models of Kenworths that are being recalled were manufactured from 2011-2016. This recall affects over 100,000 trucks.
Paccar is still developing and testing a remedy, according to the recall notice.
The specific models involved in this recall are: model year 2011-2016 Kenworth 963, T270, T370, T440, T470, C500, C540, C550, T680, T800 and W900 models manufactured from Nov. 1, 2010, to April 7, 2015.
The second recall was for 2016 Kenworth models. The recall is due to a failure to verify the rear wheel mounting torque process, which could end in the rear wheels coming off of the truck. This recall will affect nearly 50 trucks.
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.
The specific models involved in this recall are: certain Kenworth T660, T680, T800 and W900 trucks manufactured between Feb. 1, 2015, and April 20, 2015.
The third recall affects about 1500 trucks that are equipped with Paccar MX-13 engines and Delco-Remy 40SI alternators. These trucks have alternator charge cables that could cause an electrical short and start a fire.
The specific models involved in this recall are: 2014-2016 Kenworth T660, T680, T880 trucks manufactured from Feb. 18, 2013 to April 10, 2015, and 2011-2016 Peterbilt 386, 389, 567, 579 and 587 trucks manufactured from Dec. 13, 2010, to April 20, 2015.
Paccar will notify owners, and dealers will reroute the alternator cable away from the metal freon line, free of charge.
