Recall history
3 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
18V719000 · Seats
Reported: 2018-10-12 (October 12, 2018) · Model years: 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018
Transportation Collaborative, Inc. (Transportation Collaborative) is recalling certain 2011-2018 Transtech Bus SST, SST Flat Floor and ST Aero school buses, equipped with CE White/HSM SB11-26" and SB11-30" series, standard, unbelted, school bus seats, or SB11-30" series school bus seats with lap belts only. The foam in the knee impact area of the lower seat back may not absorb enough impact in the event of a crash. As such, 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: If the seat foam does not absorb enough impact energy, it can increase the risk of injury in the event of a crash.
Remedy: Transportation Collaborative will notify owners, and dealers will install a styrene strip for additional padding, free of charge. The recall began November 16, 2018. Owners may contact Transportation Collaborative customer service at 1-845-988-0419. Transportation Collaborative's number for this recall is 18E-056.
NHTSA campaign record ↗17V399000 · Equipment:Appliance:Air Conditioner
Reported: 2017-06-26 (June 26, 2017) · Model years: 2012, 2013, 2014, 2015, 2016, 2017
Transportation Collaborative, Inc. (Transportation Collaborative) is recalling certain 2012-2017 Transtech Bus ST Aero, SST, CST, Horizon, and RoadStar transit buses equipped with Bus-Air air conditioning systems. These air conditioning systems use a 30AMP in-line fuse that may short against the screw that secures the fuse holder.
Consequence: If the fuse short circuits, the holder may overheat and melt, increasing the risk of a fire.
Remedy: Transportation Collaborative will notify owners, and dealers will install an in-line mini fuse holder, free of charge. The recall began on August 21, 2017. Owners may contact Transportation Collaborative customer service at 1-845-988-0419.
NHTSA campaign record ↗20V196000 · Electrical System: Instrument Cluster/Panel | Seat Belts:Front:Warning Light/Devices
Reported: 2020-04-03 (April 3, 2020) · Model years: 2020
Trans Tech Bus (Trans Tech) is recalling certain 2020 Roadstar, ST Aero and SST buses built on 2019 Chevrolet Express cutaway chassis. The specific models are AC139SSSA409,AC139SSSP500, CC139DMSA409, CC139DMSA500, CC139DMSP500, CC159DMSA509, CC159DMSA600,EC139DBSP400, SC139DSFP500, SC139DSSA409, SC139DSSA500, SC139DSSP500, SC159DSFP600, SC159DSSA509, SC159DSSA600, SC159DSSA603, SC159DSSP600, and SC177DSSA603. The seatbelt-unfastened warning light will not illuminate for approximately five seconds after the ignition is moved to the "on" or "start" position. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Consequence: Without the seatbelt warning reminder, the driver may forget to fasten the seatbelt, increasing the risk of injury in the event of a crash.
Remedy: Trans Tech will notify owners, and GM dealers will reprogram the instrument panel cluster, free of charge. The recall began May 6, 2020. Owners may contact Trans Tech customer service 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.
2018: 0 complaints · 2020: 0 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |
|---|---|---|---|
| 2018 | 0 | 0 | 0 |

Date coverage across each selected cohort
| Year | Incident dates used | Filing date fallbacks | Excluded dates |

Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
