NHTSA Investigation EA11007
Engineering Analysis · Doubletree RV · WHEELS:LUGS/NUTS/BOLTS/STUDS
An investigation is not a finding that a defect exists.
NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
What NHTSA is examining
The agency's own description of the inquiry, quoted as published
Wheel Separations (Broken Studs)
EA11-007 is closed with the submission of recall campaign 12V-028 submitted by DRV.The population included in the campaign action includes 1,701 model year 2008, 2010, and early-2011 DRV models Select, Mobile, and Elite Suite DRV motor homes equipped with disc brakes.The absence of wheel end loosening and/or separation reports related to DRV vehicles produced after January 2011 indicates that changes in manufacturing practices that DRV adopted have improved the integrity of the wheel end system in these vehicles.Further details of this investigation are summarized in the attached closing report.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) numbers: 10357608, 10357609
