What's wrong?
The inverter in the 2020-2021 Keystone Cougar with the Off the Grid solar package takes stored battery power and supplies household 120VAC power inside the trailer. Its wiring is supposed to keep that inverter power on the intended Off the Grid inverter outlets and away from the shore power connection. That separation matters because shore power hardware is meant to receive power from an outside source, not become energized from the trailer's inverter.
On affected Cougars, the inverter input wiring from the power center and the output wiring to the Off the Grid inverter circuit were reversed. When the inverter is turned on, that backward wiring sends power to the wrong circuits. It can energize the shore power connection while the system is in use, even though the rest of the electrical system works correctly when the inverter is off.
The warning sign is specific: with the inverter on, outlets or circuits other than those labeled "Off The Grid Inverter Outlet" have power. If that happens, turn the inverter off until a Keystone service center inspects the trailer.
Who's affected?
The inverter is the listed component for both 2020 and 2021 Cougar trailers.
| 2020 Keystone Cougar | Inverter |
|---|---|
| 2021 Keystone Cougar | Inverter |
| Units affected | 1,278 |
| Field incidents | NHTSA has logged 3 field incidents to date. |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
When the inverter is on, it can energize the shore power connection and increase the risk of injury. If outlets or circuits beyond the outlets labeled "Off The Grid Inverter Outlet" have power, turn the inverter off and leave it off until service. Repair is free at any franchised Keystone dealer.
What should I do?
- Check your VIN to confirm your 2020-2021 Keystone Cougar is included in this recall.
- Contact a franchised Keystone dealer to schedule the free inverter wiring test and rewire that stops the inverter from energizing the shore power connection.
- Avoid using the inverter until the dealer confirms the shore power connection is wired correctly.
- Bring the recall notice if Keystone mailed one. If not, reference recall number 20V670 when you call.
What happens at the repair
At the dealer, a Keystone technician tests the inverter function and checks whether incorrect wiring energizes the shore power connection during use. The technician rewires the inverter as needed. Parts and labor are free under the recall. If you already paid for inverter or shore power wiring work tied to this recall, keep the repair paperwork and contact Keystone customer service about the manufacturer's reimbursement plan. New vehicles are also covered under warranty.

Frequently asked questions
What is recall 20V670?
Recall 20V670 covers 1,278 2020-2021 Keystone Cougar trailers equipped with the Off the Grid Solar package. The inverter was incorrectly wired on affected trailers, which can energize the shore power connection when the inverter is on and increase injury risk.
What should I do if my 2020-2021 Keystone Cougar is on this recall?
Check your VIN to confirm your specific trailer is included in recall 20V670. If it is, contact a franchised Keystone dealer to schedule inverter testing and rewiring as needed. Reference recall number 20V670 or Keystone recall 20-389 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. Keystone dealers will test the inverter function and rewire it as needed free of charge for trailers included in recall 20V670.
What is the safety risk?
The safety risk is electrical injury. If the inverter is turned on and the shore power connection becomes energized, someone handling that connection faces a higher risk of injury. The dealer repair addresses the wiring problem for free.
What if I bought my Keystone Cougar used?
