Summary: Tiffin is recalling 329 my 2008-2009 allegro buses. The rear axle ABS modulating valve have the potential to be wired incorrectly. The right and left modulator valve harness pin could possibly be reversed at the ABS electronic control unit (ECU) connector.
Consequence: Under slippery road conditions, when in the ABS mode, this wiring problem has the potential to cause one side of the rear wheels to lock while causing little or no braking effort on the opposite side. This may result in a loss of control and a vehicle crash.
Remedy: Dealers will remove the reversed pins from the ECU connector and insert them back into their correct position free of charge. The recall is expected to begin during April 2009. Owners may contact tiffin at 256-356-8661.

Has your Tiffin been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Tiffin dealer can also check your VIN. Recall repairs are free.
