Tires 2022-03-31 · campaign 22V209000 · 513 vehicles
Defect: Keystone RV Company (Keystone) is recalling certain 2019-2022 Cougar 29FKD travel trailers. Improper clearance may allow the tires to contact the outrigger, causing damage to the tires.
Risk: Damaged tires can fail, causing a loss of vehicle control and increasing the risk of a crash.
Fix: Dealers will notch the existing outrigger and install an additional outrigger between the two tires to provide proper clearance, free of charge. Owner notification letters were mailed May 12, 2022. Owners may contact Keystone customer service at 1-866-425-4369. Keystone's number for this recall is 22-430.
Equipment:recreational Vehicle/Trailer:lpg Systems 2021-09-13 · campaign 21V708000 · 95,885 vehicles

Defect: Keystone RV Company (Keystone) is recalling certain 2017-2021 Keystone Cougar 368MBI trailers. The frame rails do not have enough cross support, which could cause them to buckle under certain side-load stress conditions.
Risk: A buckled frame rail can increase the risk of a crash.
Fix: Dealers will add cross braces between each spring hanger and an outrigger between the tires on the off-door side of the vehicle, free of charge. Owner notification letters were mailed July 15, 2021. Owners may contact Keystone customer service at 1-866-425-4369. Keystone's number for this recall is 21-411.

The inverter may have been incorrectly wired, causing power to energize the shore power connection, when in use.
Risk: An energized shore power connection can cause an electrical shock, increasing the risk of injury.

The Solar Prep wiring to the 12VDC breakers located by the battery may not be connected to the protected side of the breaker.
Risk: Since it is not connected properly to the breaker, if the Solar Prep wiring experiences an electrical short, it will increase the risk of a fire.
Fix: Keystone will notify owners, and dealers will inspect the installation of the Solar Prep wiring at the circuit breaker mounted close to the battery and remount the wiring if needed, free of charge. The recall began January 11, 2021. Owners may contact Keystone customer service at 1-866-425-4369. Keystone's number for this recall is 21-392.

Defect: Keystone RV Company (Keystone) is recalling certain 2020-2021 Cougar trailers equipped with the Off the Grid (OTG) Solar package. The inverter may have been incorrectly wired, causing power to energize the shore power connection, when in use.
Risk: If the inverter is turned on, and energizes the shore power connection, it can increase the risk of injury.
Fix: Keystone will notify owners, and dealers will test the function of the inverter and rewire it as needed, free of charge. The recall began November, 18, 2020. Owners may contact Keystone customer service at 1-866-425-4369. Keystone's number for this recall is 20-389.

Defect: Keystone RV Company (Keystone) is recalling certain 2020-2021 Cougar travel trailers, model 24RDS, equipped with a Furrion range cook top. The interior range cooktop is installed in a cabinet that may not be entirely sealed from the furnace cavity.
