Reported: 2012-07-19 (July 19, 2012)

Collins is recalling certain model year 2012 Collins, Corbeil, and Mid-Bus school bus and multi-function school activity buses, models SL400, SH400, DH400, DH416 with 139" wheel base and two-passenger seat set at 24, 25, 26, 27, or 28" hip to knee spacing and three-passenger seat set at 24, 25, or 26" hip to knee spacing and model year 2012 DH500 and DH516 with 159" wheel base and two-passenger seat set at 28 or 29" hip to knee spacing and three-passenger seat set at 27, 28, or 29" hip to knee spacing. These buses were manufactured from March 12, 2012, through September 20, 2012. In some floor plans on these models of buses, there is the possibility that the fuel filler hose was damaged during seat or seat track installation or that a seat bolt and/or the seat bolt bracket interferes with the routing of the fuel fill hose. The fuel fill hose runs from the exterior of the bus, through a housing in the bus, then under the bus and toward the fuel tank. Some floor plans have a seat or track bolt that comes through the floor near the area where the hose crosses the chassis frame. In addition to possible damage during installation, there is a chance that the bolt or the bracket can abrade or puncture the hose in this area.

Consequence: If the integrity of this hose is breached, fuel could spill. In the case of gasoline or diesel vehicle, fuel could spill during fueling operations or in the event of a crash, increasing the risk of a fire. In the case of a propane vehicle, propane gas could be released during fueling operations (check valves prevent release from the tanks) creating the risk of a fire during filling.

Remedy: Collins will notify owners, and dealers will repair the buses free of charge. The safety recall began on August 13, 2012. Owners may contact Collins at 1-800-533-1850.

14V452000 · Fuel System, Other

Reported: 2014-07-23 (July 23, 2014)

Collins Bus Corporation (Collins) is recalling certain model year 2012-2014 DH500, DH516, DH516WR, DE500, and DE516WR school buses manufactured May 18, 2012, to May 30, 2014. In the affected vehicles, the propane fuel line may rub on the third body mount bolt on the left rear of the frame rail possibly resulting in damage to the propane fuel line.

Consequence: Damage to the fuel line may cause a propane leak which may result in a vehicle stall, increasing the risk of a crash. Additionally, a propane leak in the presence of an ignition source may result in a fire.

Remedy: Collins will notify owners, and dealers will inspect and relocate the propane fuel line, free of charge. The recall began Spetember 23, 2014. Owners may contact Collins customer service at 1-800-533-1850.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
