12V007000 · Seats
Reported: 2012-01-10 (January 10, 2012) · Model years: 2011
TRANS TECH IS RECALLING CERTAIN MODEL YEAR 2009 THROUGH 2011 SCHOOL BUSES MANUFACTURED FROM MAY 2010 THROUGH JULY 2011EQUIPPED WITH A C. E. WHITE SEAT CUSHION. THE SELF-LATCHING MECHANISM USED TO RETAIN THE SEAT CUSHION TO THE FRAME MAY NOT ACTIVATE. ACCORDINGLY, THESE SEATS FAIL TO CONFORM TO THE WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NUMBER 222, "SCHOOL BUS PASSENGER SEATING AND CRASH PROTECTION."
Consequence: IF THE SEAT CUSHION IS NOT FULLY LATCHED TO THE SEAT STRUCTURE, IT COULD FLIP UP OUT OF POSITION IN THE EVENT OF A CRASH. THIS COULD INCREASE THE RISK OF INJURY TO THE VEHICLE OCCUPANTS.
Remedy: TRANS TECH WILL NOTIFY OWNERS, AND DEALERS WILL REPAIR THE SEATS FREE OF CHARGE. THE SAFETY RECALL BEGAN ON MARCH 7, 2012. OWNERS MAY CONTACT TRANS TECH AT 1-845-988-0419.
NHTSA campaign record ↗14V180000 · Seats | Seat Belts
Reported: 2014-04-08 (April 8, 2014) · Model years: 2011
Transportation Collaborative, Inc. (TCI) is recalling certain model year 2011-2014 Trans Tech Bus school buses manufactured January 10, 2011, through March 10, 2014, and equipped with 39" seats with or without 3-point seat belts. For the full list of the affected models, click on "Associated Documents" and then please click on "Associated Documents" and then "Noncompliance Notice(Part 573)." The affected buses have seats that may not remain properly anchored to the floor. As such, these vehicles do not conform to Federal Motor Vehicle Safety Standards (FMVSS) number 207, "Seating Systems," and number 210, "Seat Belt Assembly Anchorages."
Consequence: In the event of a crash, if the seat does not remain anchored to the floor, the seat occupant has an increased risk of injury.
Remedy: TCI will notify owners and dealers will install additional mounts to secure the seats to the floor, free of charge. The recall began on April 23, 2014. Owners may contact TCI at 1-845-988-2333.

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.
