Recall 22V785 affects 540 2021-2023 Spartan K2 RV chassis for an undersized air brake reservoir. Repair is free at any franchised Spartan dealer.
Spartan is recalling 540 2021-2023 K2 RV chassis because the air brake supply reservoir is too small for the service brake chambers. During repeated braking, the reservoir can leave too little air to operate the brakes properly, reducing braking performance and increasing crash risk; Spartan dealers will complete the repair free of charge.

What's wrong?
The air supply reservoir on the 2021-2023 Spartan K2 chassis is the storage tank for compressed air used by the service brakes. When the driver presses the brake pedal, air pressure moves from that tank to the brake chambers, and those chambers use the pressure to apply the brakes at the wheels.
On affected chassis, the wet tank has 500 cubic inches of air capacity. That tank is too small for the combined volume of the installed brake chambers, including the T24, T30, and T16 chambers listed for this chassis. The reservoir is less than 12 times that combined chamber volume, so the brake system does not meet the required air reserve. Spartan says a 1000 cubic inch wet tank is installed in its place.
Before the air supply drops too low, the driver can see a low air pressure warning light and hear an audible alarm. Treat those warnings as a brake-system problem and stop in a safe place.
Who's affected?
Covers the K2 across the 2021, 2022, and 2023 model years, all tied to the same air brake reservoir.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
An undersized air brake supply reservoir can leave the brake system without enough air during repeated braking. That reduces braking performance and increases the risk of a crash. If the low air pressure telltale lights or the audible alarm sounds, pull over safely and contact the dealer before continuing. Repair is free at any franchised Spartan dealer.
What should I do?
- Check your VIN to confirm your 2021-2023 Spartan K2 is included in this recall.
- Contact your nearest franchised Spartan dealer to schedule the free air supply reservoir replacement that restores the brake air supply needed during repeated braking.
- Bring the recall notice if Spartan mailed one. If not, reference recall number 22V785 when you call.
- Avoid repeated hard braking and leave extra following distance until the repair is complete.
What happens at the repair
At the dealer, a Spartan technician replaces the air supply reservoir covered by recall 22V785. The repair is available now, and the replacement reservoir, parts, and labor are free under the recall. The service desk can confirm the chassis by VIN, open the repair order, and complete the reservoir replacement through the recall process. Spartan mailed owner letters on November 23, 2022, so bring the letter if you have it, but the VIN is what decides coverage.
