Subject: Notification of Safety Recall 21V-816, New Vehicle Hold
MYs 2012 – 2020 Avalanche M6TE, M6SE, and M6SE CNG
Outside Switch Box

 

REASON FOR THIS SAFETY RECALL:

On October 1 8, Schwarze Industries, Inc., filed a Defect Information Report with the National Highway Traffic Safety Administration (NHTSA) informing the agency that in certain Avalanche M6 sweepers, the outside switch box, from which the operator can control the position of the conveyor, can be activated unintentionally when the vehicle is running. If the vehicle operator has not completed lock out/tag out procedures and not installed the conveyor safety pins to keep the retracted conveyor in place, but enters the area between the hopper and the conveyor, the operator can unintentionally activate the switch that advances the conveyor, thereby pinning the operator between the hopper and the conveyor. This presents a crushing hazard, increasing the risk of serious injury or death.

NEW VEHICLES IN DEALER NVENTORY:

Schwarze does not believe there are any covered vehicles in dealers’ inventory. However, it is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect is remedied. Violation of this requirement by a dealer could result in a civil penalty against the dealer of up to $22,723 per vehicle. Accordingly, you must remedy covered vehicles in your new vehicle inventory before delivery.

In addition, we request that you remedy before delivery into commerce under a sale or lease any covered pre-owned vehicles in your inventory

Chronology :

On September 7, 2017, Schwarze learned of a fatality involving an M6 sweeper. A Schwarze employee’s initial inspection that day and Schwarze’s further investigation did not identify any malfunction in the vehicle.

On August 10, 2020, Schwarze learned of a fatality involving an M6 sweeper.

On August 20, 2020, Schwarze attended an inspection of the vehicle.

On September 22, 2020, Schwarze produced an initial design of a switch box guard.

On November 3, 2020, Schwarz produced the final design of the switch box guard.

On November 10, 2020, Schwarze participated in a follow-up vehicle inspection.

On December 15, 2020, Schwarze began installing the new switch box guard and crushing hazard warning decals on all M6 sweepers and began retrofitting existing units (manufactured in 2012 and thereafter) with the switch guard box and crushing hazard warning decals.

On September 10 and October 8, 2021, Schwarze met with NHTSA on the 2017 and 2020 sweeper incidents.

On October 8, 2021, Schwarze decided to conduct a voluntary safety recall to install the switch guard box and crushing hazard warning decals on the remainder of the affected M6 sweeper population. As of October 8, 2021, Schwarze is aware of no warranty claims, no field or service reports, and no injuries related to this issue.
