EA09008	PACCAR INCORPORATED	05/29/2009	08/27/2010	Horton Fan Hub Failures
	Paccar is conducting an owner notification program (onp) for select vehicles within the subject and peer populations.the onp are attached to the closing report and can be found in the nhtsa technical service bulletin (tsb) database. (tsb: 10033585, 10033584)see closing report for investigation details.
EA09008	PACCAR INCORPORATED	05/29/2009		HORTON FAN FAILURES
	During the pe odi learned that the subject vehicles are being disabled when the horton fan hub fails, due to the fan striking the radiator.apparently, warning signs of the impending failure are not always sufficient to give the driver time to pull off the highway.thus, when the failure occcurs, in some cases the vehicle is stranded and must be towed. odi has examined data which indicates that class vii and viii trucks are over represented in crashes when stranded on the highway or shoulder, as contrasted to light vehicles.further, crashes involving disabled heavy trucks being struck by light vehicles are more likely to have serious consequences. nhtsa has upgraded pe09-002 to an ea to further investigate this matter.odi will examine the warning symptoms and assess the risk of a crash in the event of a breakdown on the highway.
PE09002	PACCAR INCORPORATED	01/05/2009	05/29/2009	HORTON FAN HUB FAILURES
	There are 84,573 subject and peer (kenworth) vehicles.subject vehicles are model year 2007 through 2008 paccar trucks built with a horton fan hub assembly.the ea will include peer vehicles (kenworth's with horton fan hubs) in the subject population.there are a total of 1,645 warranty claims on the combined population.odi surveyed warranty claim owners and found that a significant number of the failures resulted in a disabled vehicle.odi also believes that certain models are more prone to failure and further analysis is warranted to understand the differences in failure rates. odi is concerned that a large disabled vehicle is at an increased risk of being struck in the rear by another vehicle.odi is also concerned that this failure mode provides little warning and therefore, a driver has less opportunity to remove the vehicle from the travel lanes or shoulder, once a fan separation has occurred.odi will conduct further risk assessment during the ea to gain an understanding of the warning, options available to the driver and the increased risk of the truck being struck in the event of a breakdown.nhtsa has upgraded pe09-002 to an ea (ea09-008) to further investigate this matter.
