What's wrong?
The adjustable brake pedal in affected 2007-2011 Tiffin Allegro, Phaeton, and Bus motorhomes lets the driver set the pedal position for reach and comfort. The pedal arm still has to stay locked on its shaft so force from your foot goes cleanly into the hydraulic brake linkage.
On these motorhomes, the Kongsberg Automotive adjustable brake pedal arm can loosen. When that happens, the arm can rotate around its shaft instead of staying in its normal position. The loose arm can swing in front of the accelerator pedal, which interferes with pedal travel and reduces braking function.
There is no warning sign before failure. A driver can first learn something is wrong when the brake pedal arm has already moved out of position or the pedals no longer feel normal underfoot.
Who's affected?
Covers three Tiffin motorhome lines from 2007-2011, all tied to the hydraulic brake system.

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?
A loose brake pedal makes braking less predictable and increases the risk of a crash. If the pedal feels loose or changes travel, pull over when safe and arrange service soon. Repair will be free at any franchised Tiffin dealer once available.
What should I do?
- Check your VIN to confirm your 2007-2011 Tiffin Allegro, Phaeton, or Bus is included in this recall.
- Review any Tiffin or DTNA owner notice before scheduling service.
- Contact a franchised Tiffin service center about the adjustable-brake-pedal repair that secures the loose pedal arm and protects braking function.
- Reference recall number 11V452 when you call, and ask whether DTNA warranty claims handles the repair paperwork.
- Drive cautiously until the repair is complete. Leave extra stopping distance and avoid using the motorhome if the brake pedal feels loose.
What happens at the repair
At the dealer, a Tiffin technician addresses the adjustable brake pedal assembly so the brake pedal arm no longer loosens, rotates around its shaft, or swings toward the accelerator pedal. The recall filing does not give a shop-time estimate or a step-by-step parts list. Because the remedy status is not listed as available, treat the final dealer repair as free once available. For repair status, contact DTNA warranty claims or Tiffin before arranging service.

Frequently asked questions
What is recall 11V452?
Recall 11V452 covers 1,960 2007-2011 Tiffin Allegro, Phaeton, and Bus motorhomes equipped with Kongsberg Automotive adjustable brake pedals. The brake pedal arm can loosen, rotate around its shaft, and swing in front of the accelerator pedal, reducing braking function.
What should I do if my 2007-2011 Tiffin Allegro, Phaeton, or Bus is on this recall?
Check your VIN to confirm your specific motorhome is included in recall 11V452. If it is, contact a Tiffin service location or DTNA Warranty Claims at 1-800-547-0712 and reference recall 11V452 when you ask about the brake pedal repair.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to perform the recall repair at no cost. For this recall, DTNA handled the repair program and owner notification, so ask the service desk to confirm the free brake pedal remedy under recall 11V452.
What is the safety risk?
The safety risk is reduced braking function. If the adjustable brake pedal arm loosens and swings in front of the accelerator pedal, the driver has less reliable brake control, which increases crash risk. Confirm the VIN, then arrange the recall repair before normal travel.
What if I bought this Tiffin motorhome used?
The free recall repair still applies. Recall coverage follows the vehicle, not the first owner. If you never received the 2009 or 2011 owner notices, check your VIN and reference recall 11V452 when you contact the service desk.
