A 60-amp solar charge controller with a 24-volt output mode is the part at the center of this recall. Grand Design RV told NHTSA that the controller’s firmware can select that mode by itself on a trailer built for 12 volts, and that the 7-way bulkhead power center behind it was not built to take the extra voltage.
The recall, filed September 24, 2026, covers 16,128 Reflection fifth-wheel trailers from model years 2024 through 2027.
An auto-detect mode that picks the wrong voltage
The defect report Grand Design filed describes a 12V/24V auto-detect solar controller, listed as an MPPT 60A wall-mount unit with Bluetooth app, part number 2023006263. The component maker is shown as Lippert Components, and the firmware fix comes from Furrion. When the controller selects 24 volts on a trailer whose electrical system is designed for 12, the output can exceed the voltage rating of the power center’s protection circuit.
The 7-way bulkhead power center is the junction between the tow vehicle and the trailer. It distributes 12-volt current to the trailer’s brake and exterior lighting circuits. The NHTSA campaign record states the consequence in two parts: damage to the power center raises the risk of a fire, and damage to the electrical system may cause the trailer brakes or exterior lights to fail, and a trailer that loses its brakes or its lights becomes a hazard to everything behind it. The filing also warns that thermal degradation of the power center can occur with little or no warning.
Three field reports before the investigation
The chronology in the report is unusually specific. Grand Design received its first report of thermal degradation at the 7-way power center on a Reflection on August 13, 2025, and a second on October 15, 2025, at which point it began monitoring for more. A third report on March 12, 2026 opened a product safety investigation.
The supplier was engaged on April 8, when design and build configurations were also reviewed across other product lines that use the same power center, and laboratory testing ran from April 13 through August 17. On August 7, testing showed that the controller could select a 24-volt output beyond the power center’s protection rating. Discussions with Furrion’s engineers began a week later, on August 14. The power center itself had been returned for evaluation on July 28, so the voltage finding came from a part that had already been pulled from the field and tested on the bench.
The company’s Brand Action Committee referred the matter to its Product Safety Committee on September 11, and that committee determined on September 17 that a safety-related defect existed and directed a recall. The report cites only the three field reports described and gives no injury or crash figures, so the case for a 100 percent defect estimate rests on the laboratory result and not on a failure count in the field.
Which Reflections are in the 16,128
Grand Design estimates that 100 percent of the covered trailers carry the defect. The population is every 2024 to 2027 Reflection built with both the auto-detect controller and the 7-way bulkhead power center, with build dates from August 8, 2023 through September 16, 2026. Trailers without the auto-detect controller, and those whose controller lacks a 24-volt mode, are excluded, and units on hand were updated before the production clean point of September 16.
An RV Travel account of the filing adds one useful detail for owners: if the brakes or exterior lighting fail, the driver may receive a fault notification through the integrated tow module. The record does not say how often that warning would fire relative to the thermal damage the filing describes.
A firmware update installed through an app
NHTSA’s record describes the remedy as an over-the-air software update, with lighting inspected and repaired as needed at no charge. The longer report fills in the mechanism. Furrion’s firmware removes the auto-detect 24-volt mode and leaves the controller in 12-volt operation only. Owners install it through the controller maker’s app, then send Grand Design a screenshot showing the firmware version and the trailer’s VIN.
Before any towing, the report tells owners to confirm that the exterior lights and brakes work, and not to tow the trailer if either fails. A “Do Not Drive Park Outside” advisory is attached to the campaign. Dealer notification is planned for October 19 to 23, with owner letters scheduled for November 16 to 20, and the schedule is phased. Owners can look up a VIN through NHTSA’s recall search or call Grand Design customer service at 1-574-825-9679, recall number 910068. The filing also appears in NHTSA’s open recall data as “Solar Controller May Select Incorrect Voltage Output.”
The report leaves one practical matter unanswered: it gives no date by which the firmware itself will be available in the controller app, only the dealer and owner notification windows that follow it.
