Recall 12V429 affects 491 2008, 2009, 2010, 2012, 2013 Spartan K2 and Mm chassis for brake drag. Free repair at a franchised Spartan dealer.

Spartan is recalling 491 Mm and K2 motor home chassis from 2008, 2009, 2010, 2012, 2013 because the front brake chambers can contact the upper control arm of the Hendrickson independent front suspension. That contact can keep the brakes from fully releasing, make the brakes self-engage, and cause loss of vehicle control; the dealer repair will be free once available.

What's wrong?

On the 2008, 2009, 2010, 2012, 2013 Spartan Mm and K2 motor home chassis, the front brake chamber is part of the air drum brake system. It uses air pressure to apply and release the front brakes. The upper control arm is part of the independent front suspension, and it helps locate the front wheel as the suspension moves.

On affected chassis, the front brake chamber sits close enough to the upper control arm that the parts contact each other. Continued rubbing damages the brake chamber area and interferes with the brake chamber returning to its released position. When the brake does not fully release, it drags against the drum. That drag builds heat, and the heat can make the brake apply even harder.

There is no warning sign before failure. Because the problem involves brake release, treat any brake drag, hot brake smell, or brake that feels stuck as a reason to stop driving and contact a Spartan dealer.

Who's affected?

Covers the Mm and K2 across five listed model years. Each listed year includes brake system and front control arm components.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.

What's the safety risk?

Unexpected brake self-engagement can cause the driver to lose control and increase the risk of a crash. If the brakes apply without driver input, slow carefully, move out of traffic, and contact a Spartan dealer for recall guidance. Repair will be free at any franchised Spartan dealer once available.

What should I do?

  1. Check your VIN to confirm your 2008, 2009, 2010, 2012, 2013 Spartan Mm or K2 chassis is included in this recall.
  2. Contact Spartan customer service at 1-800-543-4277 to confirm repair timing for your VIN.
  3. Ask a franchised Spartan service center about the free brake-chamber clearance repair that stops brake drag from the front suspension contact.
  4. Bring the owner notice if you have it. If not, reference recall number 12V429 when you call.
  5. Avoid driving if the brakes drag, overheat, or fail to release fully. Ask Spartan about the safest way to move the motor home for service.

What happens at the repair

Spartan's remedy notice says the affected vehicles will be repaired free of charge, but the provided remedy text does not name the exact repair operation or confirm an available dealer procedure. Once the dealer repair is available, a Spartan technician will address the front brake chamber interference with the upper control arm so the brakes can release fully. Parts and labor are covered under the recall. Ask the service desk to confirm the open repair for campaign 12V429 before bringing the motor home in.

Frequently asked questions

What is recall 12V429?

Recall 12V429 covers 491 Spartan 2008, 2009, 2010, 2012, and 2013 Mm and K2 motor home chassis with Hendrickson independent front suspension. The front brake chambers can contact the upper control arm, damage the brake release path, and lead to brake self-engagement.

What should I do if my 2008, 2009, 2010, 2012, 2013 Spartan Mm or K2 is on this recall?

Check your VIN to confirm your specific chassis is included in recall 12V429. If it is, contact Spartan service or your motor home dealer to arrange the recall repair. Reference recall number 12V429 when you call, and use Spartan's recall line at 1-800-543-4277 Option 1.

Is the recall repair free?

Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Spartan's remedy says the affected vehicles will be repaired free of charge. Ask the service desk to confirm the work is being handled under recall 12V429 before the appointment.

What is the safety risk?

The safety risk is loss of vehicle control from brake self-engagement. If the brake chambers contact the front suspension control arm, the brakes can fail to fully release, generate heat, drag harder, and increase crash risk. If you notice brake drag, heat, or poor release, stop using the vehicle and call for service guidance.
