What's wrong?
The 2009-2010 Stoughton Hopper is a class 8 semi-trailer built to carry bulk agricultural products, including grain. In the hopper assembly, the lower cargo area uses structural panels to contain the load and transfer weight through the trailer frame. Those panels need to sit in the correct position so their connections carry stress as designed.
On recalled trailers, one panel in the hopper assembly was placed incorrectly during original manufacture. That bad placement leaves the panel connection out of position, so repeated loaded trips put stress where the structure was not meant to take it. Over time, the connection can weaken and the lower cargo area can lose structural integrity.
There is no warning sign before failure. Do not rely on a visible crack, noise, or handling change to confirm the problem.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
An incorrectly positioned panel can separate and let cargo spill onto the roadway. The trailer also can suffer a major structural failure, and either problem increases crash risk. There is no warning sign before failure, so schedule the inspection soon and keep loads off the trailer until the hopper connections are checked. Repair is free at any franchised Stoughton dealer.
What should I do?
- Check your VIN to confirm your 2009-2010 Stoughton Hopper trailer is included in this recall.
- Contact a franchised Stoughton dealer to schedule the free hopper inspection and reinforcement of the hopper connections if needed.
- Bring the recall notice if Stoughton mailed one. If not, reference recall number 16V050 when you call.
- Avoid hauling cargo until the dealer inspects the hopper assembly and completes any needed reinforcement.
What happens at the repair
At the dealer, a Stoughton technician inspects the trailer hopper assembly and the lower cargo area connection points for the panel placement issue covered by recall 16V050. If reinforcement is needed, the dealer reinforces the hopper connections. The inspection and any required reinforcement are free under the recall. Stoughton began the recall on March 14, 2016, so the dealer repair is available now.

Frequently asked questions
What is recall 16V050?
Recall 16V050 covers 622 2009-2010 Stoughton Hopper trailers with an incorrectly positioned panel in the hopper assembly. The panel can separate, spill cargo onto the roadway, or contribute to major structural failure, increasing crash risk. Stoughton dealers will inspect and reinforce the hopper connections for free if needed.
What should I do if my 2009-2010 Stoughton Hopper is on this recall?
Check your VIN to confirm your specific trailer is included in recall 16V050. If it is, contact a Stoughton dealer to schedule the hopper inspection and reinforcement work. Reference recall 16V050 when you call, and ask whether the trailer needs hauling restrictions before the repair.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Stoughton says dealers will inspect the trailers and reinforce the hopper connections, if necessary, free of charge. The recall repair has been available since March 14, 2016.
What is the safety risk?
The safety risk is cargo spilling onto the roadway or a major structural failure of the trailer. Either failure increases crash risk for the driver and nearby traffic. If your VIN is included, arrange the free dealer inspection and reinforcement work before returning the trailer to regular hauling.
What if I bought the Stoughton Hopper used?
The free recall repair still applies. Federal recall law follows the trailer, not the first owner. Check your VIN to confirm whether your specific 2009-2010 Stoughton Hopper is included, then call a Stoughton dealer or Stoughton customer service at 1-608-873-2555 for repair scheduling.
