- Summary

In normal operation, the surge brake hitch coupler activates the trailer brakes as the towing vehicle decelerates. A transverse pin, located in the rear part of the brake actuator, may pull out of the fixed ears at its extreme ends. This would allow trailer separation, except for the safety chains.
- Remedy
- Dealer will inspect vehicle and replace defective components without charge.
- Notes

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