Federal defect investigations
NHTSA’s Office of Defects Investigation opens these when complaints point to a possible safety defect. Many end in a recall.
- Exhaust Bellows Pipe Fracture Recall
By letter dated April 15, 2013, Motor Coach Industries (MCI) notified the Office of Defects Investigation (ODI) of a safety defect that may exist in certain model year (MY) 2012 and 2013 MCI D-model coaches built from December 22, 2011 to May 19, 2012 equipped with the Cummins 2010 EPA ISX 12 Liter engine. These vehicles may have had an incorrect installation of the exhaust pipe. If installed incorrectly, the elbow pipe may prematurely fail and if a Diesel Particulate Filter regeneration event occ
- MCI Drive Shaft Safety Loop Failures
In the fall of 2011, network contacts made ODI aware of four (4) incidents of drive shaft failure on the subject buses involving a loss of vehicle control. Two of the incidents were relatively low speed non-crash events; and two resulted in motor coach rollovers. All four events showed signs of a common failure mode. The incidents and crashes studied during this investigation all resulted from a series of complex events that began with the the yoke journal ears on the drive shafts fracturing. Once t
- MCI Driveshaft Safety Loop Failures
ODI has identified certain MCI coaches with powertrain configurations that may allow a driveshaft separated at the rearward universal joint to escape the guardian structure of the steerable tag axle and damage steering and braking components. The damaged components may increase the risk of a loss of vehicle control. The subject coaches include 806 model year 1992 through 2012 MCI D and E series motor coaches with steerable tag axles. This Preliminary Evaluation is being upgraded to an Engineering

Questions
What are the most common Mci D4000 problems?
0 owner complaints are on record with NHTSA.
Is a complaint or a TSB the same as a recall?
No. A complaint is an unverified report from an owner. A technical service bulletin (TSB) is the manufacturer telling dealers how to fix a known issue; it is not a safety recall and is usually covered only under warranty. A recall is a formal safety action, and its repair is free.
How do I report a problem with my Mci D4000?
File a vehicle safety complaint at NHTSA.gov. NHTSA reads every report, and patterns of complaints are what open defect investigations and, eventually, recalls.
