- Failure of the clutch to open completely or the transmission to shift into neutral could make the vehicle difficulty to bring to a complete stop or cause the vehicle to roll forward while stopped increasing the risk of a crash.
- Remedy
- Dealers will replace the central release bearing and update the clutch actuation electronic control unit (ECU) software free of charge. The recall began on August 24, 2006. Owners may contact freightliner at 1-800-547-0712.

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