Recall history
7 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
12V345000 · Fuel System, Other | Fuel System, Diesel | Fuel System, Gasoline
Reported: 2012-07-19 (July 19, 2012) · Model years: 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.
NHTSA campaign record ↗14V452000 · Fuel System, Other
Reported: 2014-07-23 (July 23, 2014) · Model years: 2012, 2013, 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.
NHTSA campaign record ↗13V590000 · Seat Belts
Reported: 2013-11-21 (November 21, 2013) · Model years: 2013
Collins Bus Corporation (Collins) is recalling certain model year 2013 model school bus and multi-functional school activity buses manufactured August 20, 2013, through November 13, 2013 and equipped with IMMI-brand L9 seat belt buckles. When the button is pressed to release the seat belt, the latch plate can become partially engaged with the buckle, making the seat belt difficult to unlatch. Thus, the buses fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 209, "Seat Belt Assemblies."
Consequence: If the latch plate remains partially engaged after the button is pressed, egress from the vehicle could be hindered which would increase the risk of injury in the event of an emergency.
Remedy: Collins will notify owners, and dealers will inspect the seat belt buckle, and if necessary, replace the seat belt buckles, free of charge. The recall began on January 7, 2014. Owners may contact Collins at 1-800-533-1850.
NHTSA campaign record ↗14V523000 · Structure:Body
Reported: 2014-09-03 (September 3, 2014) · Model years: 2014
Collins Bus Corporation (Collins) is recalling certain model year 2014 Collins and Mid Bus school buses, models SL400, SL408, DH400, DH416, DE416WR, DH500, DH516 and DE516WR, manufactured from July 21, 2014, to August 19, 2014. The affected vehicles may have been assembled with an inadequate amount of adhesive on some interior side panel joints. In the case of a collision to the side of the vehicle, the edge interior panel may become exposed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 221, "School Bus Body Joint Strength."
Consequence: If the edge interior panel becomes exposed, there is an increased risk of injury to the passengers.
Remedy: Collins will notify owners, and dealers will install additional structural fasteners on the applicable body panel joints, free of charge. The recall began on October 8, 2014 . Owners may contact Collins customer service at 1-800-533-1850.
NHTSA campaign record ↗15V307000 · Seats
Reported: 2015-05-26 (May 26, 2015) · Model years: 2015
Collins Bus Corporation (Collins) is recalling certain model year 2015 DE516WR, SL408, SH40, and DH500 school buses manufactured February 2, 2015, to April 1, 2015. The affected vehicles have seat bottoms whose foam core may not meet the flammability requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 302, "Flammability of Interior Materials."
Consequence: If the seats are built with this seat bottom foam core, the seats may not resist catching fire in the presence of an ignition source, increasing the risk that a fire may start or spread.
Remedy: Collins will notify owners, and dealers will replace the school bus seat bottoms with foam that is compliant to the safety standard, free of charge. The recall began on June 25, 2015. Owners may contact Collins customer service at 1-800-533-1850. Collins' number for this recall is 15E032.
NHTSA campaign record ↗16V031000 · Other:School Bus Stop Arm Assembly
Reported: 2016-01-22 (January 22, 2016) · Model years: 2015
Collins Bus Corporation (Collins) is recalling certain model year 2015 DE416, DE416WR, DE500, DE516, DE516WR, DH400, DH416, DH416WR, DH500, DH516, SH400, SL400, TH400, and TL400 school buses manufactured May 1, 2015, to December 21, 2015, equipped with certain Transpec T6000, T6100, and T7000 series school bus stop arms. The affected stop arms have a reflective decal that may peel loose from the stop arm. As such, these stop arms fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 131, "School Bus Pedestrian Safety Devices."
Consequence: Without a reflective decal, the stop arms would have reduced visibility to other drivers, increasing the risk of a crash.
Remedy: Collins will notify owners, and the stop arm blade assemblies will be replaced, free of charge. The recall began on February 22, 2016. Owners may contact Collins customer service at 1-800-533-1850, or Transpec customer service at 1-800-951-7867.
NHTSA campaign record ↗19V211000 · Seats:Barriers
Reported: 2019-03-19 (March 19, 2019) · Model years: 2015, 2016, 2017, 2018, 2019
Collins Bus Corporation (Collins Bus) is recalling certain 2015-2019 Midbus DH500, DH516, DH400, DE416, DE500, DE516, TH400, SH416, and SH400 school buses equipped with HSM 39-INCH FB11 restraining barriers. In a hard braking situation or vehicle crash event, the barrier may not properly restrain an unbelted seat occupant. As a result, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 222, "School Bus Passenger Seating and Crash Protection."
Consequence: Failure to properly restrain an unbelted seat occupant can increase the risk of injury.
Remedy: Collins will notify owners, and HSM dealers will reinforce the barrier frame, free of charge. The recall began April 12, 2019. Owners may contact Collins customer service at 1-800-533-1850, extension 424. Collins' number for this recall is 19E-010.
