Grand Design RV Recall LP Regulator – 55K Units Affected

Grand Design RV Recall LP Regulator problem. Excessive gas pressure and a larger than intended appliance flame can increase the risk of a fire.

Grand Design RV, LLC (Grand Design) is recalling certain 2016-2021 Imagine, Transcend, and Momentum travel trailers. The LP regulator that controls the LP gas pressure may fail, allowing excessive gas pressure that causes the appliance flame to increase.

NHTSA Campaign Number: 21V393000
Manufacturer Grand Design RV, LLC
Components EQUIPMENT

Potential Number of Units Affected 55,508

Grand Design began receiving reports of thermal events at LP gas appliances beginning in September 2020. Investigations revealed a potential defect in the Winntec LP regulator. Independent 3rd party lab testing eventually confirmed that the regulator was failing, resulting in high pressure LP gas being pushed to the appliances, creating the potential for a thermal event or fire.

The LP regulator controls the LP gas pressure to the appliances. Appliance manufacturer’s installation instructions require 10-14 inches of water column, with 11 inches as optimal.

LP regulators are pre-set at 11 inches of water column from the manufacturer. Multiple tests are performed in the vehicle manufacturing process to confirm proper setting. It was discovered that the
Winntec regulators were failing in the field after a period of time, pushing as much as five (5) times the allowable pressure to the appliances.

As a result, the flame at the appliances grows significantly, creating the potential for a fire.

The Grand Design RV Recall LP Regulator affects 55,508 Grand Design Imagine, Transcend & Momentum travel trailer vehicles in model years 2016 through 2021.

Recall population includes all vehicles that were built with a Winntec LP regulator. Other products use LP regulators from other manufacturers/suppliers and are not affected by this recall.


Dealers will replace the LP regulator, free of charge. Owner notification letters are expected to be mailed June 28, 2021. Owners may contact Grand Design customer service at 1-574-825-9679. Grand Design’s number for this recall is 910023.

  1. Our furnace on our 2019 Imagine wasn’t working. All the other LP appliances were working fine. We had the regulator replaced due to the recall. The furnace is working fine now.
