NHTSA Service Bulletin 10155162: 2019 Tiffin Bus
Official manufacturer communication context for 2019 Tiffin Bus, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
On certain 2019 Buses, there is a possibility that the spoiler on the rear cap may not be securely fastened. If the spoiler is not secured it may come off. We orginally had 96 in this service bulletin. Tiffin made production start gluing these in our production line at the time of the service bulletin, but through a communicatio error, only 15 were glued and then they quit. Therefore, we have went back to the last unit of the 96 prior and expanded the recall to where we started gluing again. We have added 178 more units to this service bulletin.
What this bulletin may mean before buying
Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
