What's wrong?
The electric water heater in 2021 Kzrv Sporttrek and Stratus trailers uses a dedicated circuit to carry power to the appliance. The circuit breaker is supposed to protect that wiring by opening the circuit when electrical load exceeds what the wire is built to handle.
On these trailers, circuits using 14/2 wire were connected to a 20 amp circuit breaker. That breaker is too large for the wire protection described in the recall, so it can fail to trip when the wire needs protection. The issue traces to a production error after a wire supply change, not to normal owner use or maintenance.
There is no warning sign before failure. An owner should not expect the water heater, breaker panel, or trailer controls to give a clear advance symptom before the circuit is overloaded.
Who's affected?
Covers Sporttrek and Stratus trailers from the same model year, both tied to the electric water heater circuit breaker.

A matching 2021 Kzrv Sporttrek or Stratus does not guarantee inclusion. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
Inadequate wiring protection raises the risk of a fire. There is no warning sign before the problem becomes dangerous, so treat VIN inclusion as the reason to arrange service. If your VIN is included, schedule the recall repair soon and ask the dealer about safe use before the appointment. Repair is free at any franchised Kzrv dealer.
What should I do?
- Check your VIN to confirm your 2021 Kzrv Sporttrek or Stratus is included in this recall.
- Contact your nearest franchised Kzrv dealer to schedule the free 20 amp to 15 amp circuit-breaker replacement that restores water-heater wiring protection.
- Bring the recall notice if you have it. Reference recall number 21V397 when you call.
- Avoid using the electric water heater until the dealer completes the breaker replacement.
What happens at the repair
At the dealer, a Kzrv technician replaces the water heater circuit breaker from the incorrect 20 amp breaker to the specified 15 amp breaker. That lower-rated breaker is the part that protects the wiring by tripping when the circuit is overloaded. The recall repair is available now, and parts and labor are covered. Before the trailer is returned, ask the service desk to confirm that the water heater circuit breaker was replaced and that the repair was recorded under this recall.
