Recall 12V155 covers 1 2012 Midsoda ST-22 trailer for an E/H brake actuator pump defect. A Dexter Axle dealer replaces the actuator for free.
Midsoda is recalling one 2012 ST-22 trailer because the Dexter electric/hydraulic brake actuator pump has a heat-treatment defect that can wear critical parts early and leave the actuator inoperable. If your VIN is included, the trailer can lose braking effort and raise crash risk; the Midsoda dealer repair will be free once available.

What's wrong?
The electric/hydraulic brake actuator pump on the 2012 Midsoda ST-22 trailer is the bridge between the tow vehicle's brake signal and the trailer's hydraulic brakes. When the driver brakes, the actuator uses an electric command to pressurize brake fluid for the trailer brakes. That pressure lets the trailer slow with the tow vehicle instead of pushing against it.
On this trailer, the Dexter Axle actuator pump was not properly heat treated. Heat treatment hardens internal metal parts so they resist wear while the pump builds pressure. Without the correct treatment, critical parts inside the pump wear too soon. As wear builds, the pump can stop working and the actuator can become inoperable.
There is no warning sign before failure. An owner should not count on noise, a light, or a gradual change in brake feel to appear before the actuator stops working.

Not every 2012 Midsoda ST-22 trailer is on the list. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
The E/H brake actuator supplies braking power to the trailer brakes. If it fails, the trailer can lose braking effort, which increases the risk of a crash. Keep extra stopping distance and schedule the recall repair soon. Repair will be free at any franchised Midsoda dealer once available.
What should I do?
- Check your VIN to confirm your 2012 Midsoda ST-22 is included in this recall.
- Wait for Midsoda's owner notice, then confirm the free repair is open before scheduling service.
- Contact a Midsoda dealer and ask about the Dexter Axle electric/hydraulic brake-actuator replacement that restores trailer braking power.
- Reference recall number 12V155 when you call or bring the owner notice if you received one.
- Drive cautiously until the repair is complete. Allow extra stopping distance because trailer braking effort can be reduced if the actuator fails.
What happens at the repair
At the dealer, a Midsoda technician replaces the Dexter Axle electric over hydraulic brake actuator pump. The repair path is a full actuator replacement, not an adjustment to the pump. The dealer repair will be free once available, with parts and labor covered under the recall. The filing does not list a separate reimbursement plan, so keep the service paperwork for your own records after the trailer leaves the shop.

Frequently asked questions
What is recall 12V155?
Recall 12V155 covers 1 2012 Midsoda ST-22 trailer equipped with a Dexter Axle electric/hydraulic brake actuator pump that was not properly heat treated. Premature wear inside the pump can make the actuator inoperable and reduce trailer braking power. A Dexter Axle dealer will replace the actuator for free.
What should I do if my 2012 Midsoda ST-22 is on this recall?
Check your VIN to confirm your specific trailer is included in recall 12V155. If it is, contact a Dexter Axle dealer to schedule the actuator replacement. Reference recall number 12V155 when you call. The repair is free.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost, and the remedy for recall 12V155 is a free replacement of the electric/hydraulic brake actuator by a Dexter Axle dealer.
What is the safety risk?
The safety risk is loss of trailer braking effort. The electric/hydraulic actuator supplies braking power to the trailer brakes, and actuator failure increases crash risk. If your VIN is included, arrange the free actuator replacement before using the trailer again.
What if I bought this trailer used?
The free recall repair still applies. Recall coverage follows the trailer, not the first owner. Check your VIN to confirm whether your 2012 Midsoda ST-22 is included, then reference recall number 12V155 when you contact a Dexter Axle dealer.
