Recall 11V412 affects 313 2011-2012 Spartan K2, K3, Mm, and Su chassis for inaccurate air-brake gauges. Repair is free at any franchised Spartan dealer.
Spartan is recalling 313 2011-2012 K2, K3, Mm, and Su recreational vehicle chassis because inaccurate air brake gauges can show the wrong pressure reading. In constant braking, the air system can deplete sooner than expected, applying the spring brake without warning and raising crash risk; Spartan dealers will complete the repair free once the remedy is available.

What's wrong?
The 2011-2012 Spartan K2, K3, Mm, and Su chassis use air pressure gauges for the air brake system. The gauge tells the driver how much air pressure is available and helps confirm that the compressor has built pressure before the coach moves. Air brakes depend on stored air pressure, so the gauge reading has to match the system closely.
On these chassis, the supplier used the wrong value when calculating the dial's sweep angle. The sweep angle is the arc the needle travels across the face of the gauge. Because that arc was calculated incorrectly, the needle can point to a reading that is off by as much as eleven percent from cutout pressure, instead of staying within the allowed +/- seven percent range.
There is no warning sign before failure. The issue is the gauge accuracy itself, so the driver sees a normal-looking dial even when the reading is not accurate enough.
Who's affected?
K2, K3, and Mm span both model years; Su appears only for 2011. All listed models are tied to the brake system.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
Under constant braking, the air systems can deplete sooner than expected. That can apply the spring brake without warning and result in a crash. If your VIN is included, avoid heavy braking conditions until the dealer completes the recall repair. Repair will be free at any franchised Spartan dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2012 Spartan K2, K3, Mm, or Su chassis is included in this recall.
- Call Spartan customer service at 1-800-543-4277 to confirm repair instructions for your chassis.
- Ask about the free air-gauge replacement that corrects the inaccurate brake-system pressure reading.
- Reference recall number 11V412 when you call or speak with a Spartan service contact.
- Avoid long downhill braking or repeated braking until Spartan confirms the recall repair is complete.
What happens at the repair
The remedy Spartan described for campaign 11V412 is replacement of the affected air gauges with compliant gauges. Because the current remedy status is not listed here, confirm scheduling with a Spartan service desk before taking the chassis in. Once the dealer repair is available for your VIN, a Spartan technician replaces the affected gauges, and parts and labor are covered by the recall. Ask the service desk to match the repair order to Spartan campaign 11018 so the correct gauge work is documented.

What is recall 11V412?
Recall 11V412 covers 313 2011-2012 Spartan K2, K3, Mm, and Su recreational vehicle chassis with air brake gauges that do not meet the required accuracy standard. In constant braking, the air system can deplete sooner than expected and apply the spring brake without warning.
What should I do if my 2011-2012 Spartan K2, K3, Mm, or Su is on this recall?
Check your VIN to confirm your specific chassis is included in recall 11V412. If it is, contact a franchised Spartan service location to schedule gauge replacement. Reference recall number 11V412000 when you call, and use Spartan's recall contact line at 1-800-543-4277 if scheduling is unclear.
Is the recall repair free?
Yes. Spartan's remedy for recall 11V412000 is replacement of the affected air gauges with compliant gauges free of charge. Federal recall law requires the manufacturer to repair the covered safety defect at no cost to the owner.
What is the safety risk?
The risk is unexpected spring brake application after the air system depletes sooner than expected during constant braking. Spartan's filing for recall 11V412000 says that condition increases crash risk. Confirm your VIN, then arrange the free gauge replacement if your chassis is included.
