Recalls 4
Seats
- What is wrong
- Daimler Buses North America (DBNA) is recalling certain model year 2010-2012 Orion VII transit buses manufactured April 5, 2010, to October 31, 2012, equipped with certain Recaro Ergo-M Commercial Bus Driver Seats. The affected seats have J-Brackets that may be missing welds which could allow the seat belt anchorage assembly to separate from the J-Bracket.
- Risk
- If the seatbelt anchorage assembly separates from the J-Bracket, the bus driver may not be properly restrained in the event of a crash, increasing their risk of injury.
- Remedy
- DBNA will notify owners, and dealers will inspect the seats to determine if welds are missing. Any J-Bracket that is missing welds will be removed and replaced, free of charge. The recall began on February 29, 2016. Owners may contact DBNA customer service at 1‑905‑403‑1111.
Recall number 16V017000 · Recall details
Engine and engine cooling: engine
- What is wrong
- Daimler Buses North America (DBNA) is recalling certain model year 2007-2012 Orion VII natural gas-powered transit buses manufactured January 1, 2007, to October 1, 2012. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
- Risk
- If the engine oil comes into contact with hot surfaces, it can increase the risk of a vehicle fire.
- Remedy
- Cummins will notify owners on behalf of DBNA, and dealers will secure the ends of the 90-degree elbow. In addition, the electronic control module (ECM) will be reprogrammed with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact DBNA at 1‑905‑403‑7807 or Cummins Inc. at 1‑800‑343‑7357.
Recall number 15V288000 · Recall details
Engine and engine cooling: engine
- What is wrong
- Daimler Buses North America (DBNA) is recalling certain model year 2007-2012 Orion VII transit buses manufactured January 2007 through October 2012 equipped with certain Cummins Westport Model ISL G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
- Risk
- The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
- Remedy
- Cummins Inc. and Cummins Wesport Inc. will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recall began on April 12, 2014. Owners may contact DBNA at 1‑905‑403‑7807 or Cummins Inc. at 1‑800‑343‑7357. Cummins' number for this recall is C1462 (for ISL G engines) or C1461 (for ISX12 G) engines.
Recall number 14V106000 · Recall details
Parking brake: driveline: air: chamber
- What is wrong
- Daimler Buses North America (DBNA) is recalling certain model year 2011-2012 Orion VII transit buses equipped with disc brakes using MGM brake components. In the affected vehicles, the brake chambers may leak pressure allowing the parking brake to drag when it is supposed to be released. Brake dragging could lead to overheated brake components.
- Risk
- Overheated brake components could result in a fire.
- Remedy
- DBNA will notify owners and will replace the affected brake chambers, free of charge. The safety recall began on March 7, 2013. Owners may contact Daimler Buses North America at 1‑800‑882‑8054.

Defect investigations
Coolant Leak Resulting in Occupant Burns
ODI is aware of three (3) incidents of heater hose failures on the delivery circuit (high temperature) of the engine coolant system on the subject transit buses.The failure occurs in the vicinity of the air ducts above the street-side passenger compartment.The air ducts may quickly fill with engine temperature fluids that are expelled without warning onto the seats below.ODI is aware of no injuries at this time.The heater hose in question was only installed as original equipment on fifty-two (52) buses in a single fleet.At this time all 52 hoses have had the hose replaced with a standard higher working pressure hose.Daimler Buses NA, the manufacturer of the buses, has gone out of business.Therefore, in view of the need to allocate and prioritize the federal safety agency's limited resources to accomplish the agency's safety mission, ODI is closing this investigation.The ODI report cited above can be reviewed at www-odi.the federal safety agency.dot.gov/owners/Searchreference under the following identification (ODI) number: 10500221
