A port authority owned 2006 orion vi diesel powered airport shuttle bus was destroyed by fire on 6/28/08 at about 12:00 a.m. Fortunately the bus was not carrying passengers at the time, as the fire spread quickly and destroyed the bus even though it was equipped with an on-board fire suppression system that discharged agent into the engine compartment. Following an investigation by a forensic engineer with extensive experience in diesel fires, it was determined that the probable cause of the fire was the wear and shorting of wires from the alternator that were chaffing on the #5 cylinder diesel injector line. Upon removal it was discovered that the line was melted and a hole burned through the steel tube allowing the spraying of high pressure diesel fuel. Upon investigating other buses of the same manufacturing group approximately 15 out of 17 buses displayed at least some wear, and 7 had physical grooving on the injector line.

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.

- 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.

- What is wrong
- Daimler Buses North America Ltd. (DBNA) is recalling certain model year 2003-2008 Orion V and model year 2002-2010 VII buses equipped with Sure Power equalizers and DC-DC Converters. The specific potting compound used in the equalizers and convertors for insulation was found to be capable of conducting electricity after being exposed to heat.
- Risk
- Once electrically conductive, the material is capable of melting and burning, increasing the risk of a fire.
- Remedy

Seats: front assembly: seat heater/cooler
- What is wrong
- Daimler bus is recalling 804 my 2006-2009 transit buses equipped with a new york custom seat heater. Currently, the terminal connection of the seat heater is immediately located next to the seat bus bar. Should conductive material or debris, such as a washer, enter between the terminal connection and the seat bus bar, a short circuit could occur.
- Risk
- A short circuit between the seat bus bar and the adjacent terminal connection could overheat the wire, possibly resulting in a fire.
- Remedy
- Dealers will inspect buses for debris and will relocate the terminal connection away from the bus bar. This service will be performed free of charge. The recall is expected to begin during april 2009. Owners may contact daimler buses at 905‑403‑7807.

Engine and engine cooling: engine: diesel
- What is wrong
- Daimler buses is recalling 175 my 2004-2008 orion v and vii buses equipped with a cummins isl diesel engines. Due to various alternator cable routing configurations, it may be possible for the cable to rub on engine components.
- Risk
- When the cable rubbing is not detected during regular maintenance inspections, the insulation can rub to expose the electrified cable. Arcing can cause a fire to occur.
- Remedy
- Daimler buses will reroute the alternator cable to ensure that the cable does not contact engine components. The recall is expected to begin on or before january 2009. Owners may contact daimler buses at 1‑800‑716‑7466.

- Remedy
- Owners will be provided with instructions and parts to replace the 5 amp circuit breaker with a 2 amp fuse to mitigate the failure of the ucm from subsequently causing a fire. The recall began on january 25, 2008. Owners may contact dcbusna/orion bus at 905‑403‑7832.
Recall number 07V379000 · Recall details
Engine and engine cooling: exhaust system
- What is wrong
- On certain transit buses built with cummins isl engines, the exhaust elbow was incorrectly assembled and welded during production. The upper flange has a butt type weld instead of a fillet type weld.
- Risk
- An exhaust system that is not maintained to ensure that there are no leaking sections can cause heat damage to surrounding components increasing the risk of a fire.
- Remedy

Defect investigations
Falling bus windows
The purpose of this investigation was to determine whether the tip-in style transom windows supplied to daimler buses for use on buses it manufactured, and concerning which that company made a defect determination, were supplied to any other vehicle manufacturers or as replacement equipment and, if so, to prompt additional safety recalls if and where needed.rmd issued a request for information to the windows' manufacturer, hehr international, inc. (hehr) on september 2, 2009, inquiring about its distribution of the windows and soliciting its opinion as to whether a safety defect existed in those windows.hehr responded on october 28, 2009, that it had not supplied the windows to anyone other than daimler buses.it also opined that the windows did not contain a safety defect and that any screw loosening, and consequential window collapse, would be due to a failure to properly retighten a screw after maintenance, as opposed to a defect inherent to the design or manufacture of the screws or windows.in support of its opinion, it provided a summary of historical field data and its field inspection investigation, neither of which demonstrated aberrant performance.it also provided a summary of testing conducted by an independent testing facility demonstrating that the screws would not loosen as manufactured. In view of hehr's response and the information provided therein, this investigation is closed.
