THE AUTO PARK BRAKE ON OUR 1992 SAFARI MOTORHOME ON A CHEVY P30 CHASSIS LOCKS UP WHEN PUT INTO PARK AND WILL NOT RELEASE. MORE SIGNIFICANTLY THE AUTO PARK BRAKE ATTEMPS TO LOCK WHILE IN MOTION. AFTER REVIEWING THE WWW, I HAVE LEARNED THIS IS A COMMON PROBLEM THAT MANY RVERS FACE. THE GMC WORKHORSE DEALER THAT IS RESPONSIBLE FOR THIS CHASSIS CANNOT REPAIR THE PROBLEM. GM DOES NOT APPEAR TO PROVIDE A SOLUTION. MANY RVERS ARE REPORTING THAT THEIR "SOLUTION" IS TO DISABLE THE PARKING BRAKE. THIS IS OBVIOUSLY UNDESIRED.*AK

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.
