This Preliminary Evaluation (PE14006) was opened after NHTSA became aware of alleged steering lockup involving Victory Vision motorcycles built by Polaris Industries, Inc. (Polaris).This issue has been the subject of numerous online forum posts by the filer of VOQ 10534733.Both the VOQs and forum posts (from all sources) formed the foundation of our investigation. The subject motorcycles are equipped with a two-piece, plastic, front fender.The back half (the all-black portion in the photo below) is secured to the fork with a single fastener on each side.It is secured to the front half of the fender with two plastic pushpins.The back half of the subject 2-piece fender is alleged to cause steering lockup when it partially separates and becomes wedged in the lower faring.We have expanded the PE's original scope to include the MY2014 and 2015 Visions because (1) these bikes came on-line after we opened this investigation and (2) the subject fender remains unchanged.Since its introduction in May, 2007, Polaris has produced 7,337 Visions (and trim derivatives).In the 8 years since, we are aware of 35 incidents of partial fender separation wherein the fender wedged in the lower fairing opening.None of the incidents involved a crash.During testing, with the fender both wedged in the lower fairing and with it pinned in the seam joining the right and left lower fairing halves, we noted a ?notchy? steering feel but no steering lock-up.At no time was steering control lost in either circumstance (wedged and/or pinned).When the front forks were rotated at angles greater than 10 degrees, and vehicle speed was, by necessity, below 10mph we noted an increase in steering effort that was easily manageable.This is consistent with the results of Polaris? testing where steering effort increased at steering angles beyond ten degrees.Such steering angles were only reasonably obtainable at speeds below ten mph.Polaris concluded that a fender separation of the type owners allege, does not represent an unreasonable risk to motor vehicle safety, but does compromise owner satisfaction.Consequently, on April 28, 2015, Polaris advised the agency that it decided to undertake a consumer satisfaction campaign to improve fender durability on all MY 2008-15 Victory Vision motorcycles regardless of mileage, time in service, or ownership status.Owners will receive notification of this campaign by June 20, 2015.A copy of Polaris' April 28, 2015 letter to us about this program is in the public file for this PE.In light of the low risk to motor vehicle safety as a result of displaced fenders, and Polaris?s actions to reduce the likelihood of fender interference through a consumer satisfaction campaign, further use of agency resources does not appear to be warranted.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency reserves the right to take further action if warranted by the circumstances.For additional detailed information on this investigation, see the attached closing report.The ODI complaints cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following (ODI) numbers: 10534913, 10535066, 10430546, 10469285, 10468997, 10592181, 10585428, 10534743, 10597031, 10535938, 10594160, 10594161, 10606364
