What's wrong?
The exhaust pipe on the 2010-2012 Tiffin Phaeton carries hot engine gases away from the engine and out through the tailpipe. It runs under the coach floor, where the system needs enough clearance so exhaust heat stays away from the floor structure and interior materials.
On included Phaeton motorhomes with QBH, QKH, and QTH floor plans built on Powerglide chassis, the exhaust pipe sits too close to the underside of the floor. Tiffin first tried adding a heat shield to the floor and wrapping the exhaust with insulation. That repair did not move enough heat away from the floor, so Tiffin changed the remedy to reroute the exhaust farther from the floor instead of relying on wrap.
There is no warning sign before failure. An owner should not expect a light, sound, or drivability change before heat damage starts.
Who's affected?
Spans the 2010, 2011, and 2012 Phaeton model years, with the same exhaust-system component listed for each year.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific motorhome is included.
What's the safety risk?
Insufficient clearance between the exhaust pipe and the floor can melt insulation and increase the risk of a fire. Schedule the recall repair soon, even if the vehicle was repaired under an earlier campaign for this condition, because this recall uses a revised remedy. Repair is free at any franchised Tiffin dealer.
What should I do?
- Check your VIN to confirm your 2010-2012 Tiffin Phaeton is included in this recall.
- Contact your nearest franchised Tiffin dealer to schedule the free exhaust reconfiguration that adds clearance between the exhaust pipe and floor insulation.
- Bring the recall notice if Tiffin mailed one. Reference recall number 15V612 when you call.
- Tell the dealer if the motorhome was repaired under recall 11V416 before; this recall requires the revised exhaust-clearance remedy.
- Limit driving until the repair is complete, and stop safely if you smell burning insulation or see smoke.
What happens at the repair
At the dealer, a Tiffin technician changes the exhaust configuration to create extra clearance between the exhaust pipe and the underside of the floor. Parts and labor are covered under the recall. If this motorhome was already repaired for the same condition under recall 11V-416, it still needs the revised remedy for recall 15V612. Tiffin has a general reimbursement plan on file for owners who already paid for related exhaust clearance repairs. Keep repair paperwork and ask Tiffin customer service how to submit the claim.

Frequently asked questions
What is recall 15V612?
Recall 15V612 covers 140 2010-2012 Tiffin Phaeton motorhomes built on Powerglide chassis with QBH, QKH, and QTH floor plans. The exhaust pipe sits too close to the underside of the floor, which can melt insulation and increase fire risk.
What should I do if my 2010-2012 Tiffin Phaeton is on this recall?
Check your VIN to confirm your specific motorhome is included in recall 15V612. If it is, contact a franchised Tiffin dealer to schedule the exhaust reconfiguration. Reference recall number 15V612 when you call. The repair is free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Tiffin dealers will change the exhaust configuration free of charge to add clearance between the exhaust pipe and the floor.
What is the safety risk?
The safety risk is fire. The exhaust pipe is mounted too close to the underside of the floor, so heat from the exhaust can melt insulation and increase the risk of a fire. Check your VIN, then arrange the free dealer repair if your motorhome is included.
What if my Phaeton was already repaired under recall 11V-416?
Your motorhome still needs this recall checked. Tiffin says vehicles previously repaired for this condition under recall 11V-416 need the revised remedy for recall 15V612. Check your VIN and ask the dealer to confirm whether the updated exhaust configuration is complete.
