NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE10-040.
As a part of PE10-040 investigation activities for both monitoring and to provide candidates for on-site field examinations, ODI had requested Doubletree RV (DRV) to inform ODI of all newly reported wheel separation incidents.
DRV has reported two newly-reported incidents since October, 2010. (1) On November 3, 2010, DRV reported the complete separation of the left (driver side) - forward wheel assembly mounted to a 2010 model year DRV Mobile Suites RV equipped with aluminum wheels mounted on eight 9/16 wheel mounting studs.(2) On May 2, 2011, DRV reported the complete separation of the right (passenger side) - rear wheel assembly mounted to a 2010 model year Elite Suites RV equipped with aluminum wheels mounted on eight 5/8 wheel mounting studs.
ODI, in conjunction DRV representatives, visited and inspected both of these vehicles shortly after receiving notification of the incident (before repairs were attempted) for the purpose of identifyingcontributory issues associated with components, component interfaces, and/or maintenance issues prior to pertinent evidence being lost or altered in the repair process.***** To improve the mounting surface quality in new production vehicles, DRV instructed that paint be removed from hub faces as of January, 2011.
DRV also issued an owner letter in January, 2011 advising owners to check lug nut torque and notify DRV in the event of any owner concerns or problems regarding loosening or inability of the wheel retention system to maintain the specified torque.***** The occurrence of a wheel end separation incidents prompts concern about the wheel end retention integrity of DRV units in the field and justifies further investigation activity.

Mobile Suites
All Mobile Suites recallsWhat an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
