Summary: On certain motor homes equipped with caterpillar 3126E hydraulically controlled electronically actuated unit injected diesel engines with high efficiency pumps (HEP8). The pump components may experience a high pressure seal failure which can result in a short period of rough running and subsequent engine stall due to a loss of injection actuation pressure.
Consequence: Once engine stall occurs, the engine cannot be restarted, increasing the risk of a crash.
Remedy: Caterpillar is conducting the owner notification and remedy for this campaign. Dealers will inspect the pump serial numbers and replace the pump if necessary. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact caterpillar at 1-800-447-4986 or winnebago at 1-641-585-6966.
Notes: Also, customers can contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).

Has your Itasca 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 Itasca dealer can also check your VIN. Recall repairs are free.
