I just read this research from Wells
"** Polaris issued a stop sale and stop ride notice on all Slingshot vehicles due to potentially defective ball bearings in the steering rack, which could lead to loss of steering control. Polaris is also voluntarily replacing the roll hoops on certain Slingshots which may not meet performance standards. The initial alert was sent to Polaris dealers on January 16, with Formal Safety Bulletins to be delivered on January 21. Service parts will be available for order starting January 22. Polaris will cover the costs of necessary repairs and replacement parts.
** Polaris is still seeing pushback from regulators in Texas (largest concern), Indiana, Maryland, Connecticut, Hawaii and most of Canada regarding the classification/safety standards of the Slingshot. We believe most of these issues will be resolved, but will take time to sort out in some cases through legislative proceedings.
** Conclusion. We believe the recall and regulatory issues could lead to a material shortfall for Slingshot versus our Q4 2014 estimate of 1,080 units shipped and 2015 estimate of 4,205 units shipped (skewed towards the first half of 2015).
