PARKING GEAR AND EMERGENCY BRAKING SYSTEM FAILED IN CHEVY MOTOR HOME, CAUSING CAMPER TO ROLL AND CRASH ON 2 DIFFERENT OCCASIONS. 1ST CRASH OCCURRED ON 7/1/06 CAUSING PROPERTY DAMAGE TO ANOTHER PASSENGER CAR. REPORT WAS FILED WITH NHTSA FOR THIS ACCIDENT. IMMEDIATELY AFTER ACCIDENT I CHECKED THE PARKING GEAR AND NO PARKING GEAR, AND NO EMERGENCY PARK, AS IN THIS MODEL BOTH ARE TIED TOGETHER. MANUALLY PLACING FOOT ON BRAKE PEDAL IS THE ONLY WAY TO KEEP VEHICLE FROM ROLLING. CAMPER WAS SERVICED BY GM AUTHORIZED SERVICE DEALER IN 8/06. SECOND ACCIDENT OCCURRED IN 7/08 WHEN EXACT SAME PARKING GEAR/EMERGENCY BRAKE SYSTEM FAILED WITH CAMPER ROLLING INTO A GARAGE CAUSING DAMAGE TO CAMPER AND GARAGE. POLICE REPORT TAKEN AND INSURANCE CLAIM MADE. AGAIN NO PERSONAL INJURIES OCCURRED. IT SHOULD BE NOTED THAT THIS SECOND ACCIDENT OCCURRED AFTER COMPLETE SERVICING OF PARKING GEAR AND EMERGENCY BRAKE BY A GM DEALERSHIP. SECOND ACCIDENT OCCURRED AFTER SPENDING 1,978.94 AT A GM AUTHORIZED DEALER. THIS IS THE SECOND COMPLAINT FOR SAME PROBLEM AFTER REPAIR. 1ST COMPLAINT ALSO FILED WITH GM THROUGH ESIS - GM'S 3RD PARTY ADMINISTRATOR. GM/ESIS DID NOT COVER ANY COSTS OF 1ST ACCIDENT. NATIONWIDE INSURANCE PAID FOR OTHER VICTIMS DAMAGED CAR. GM DID NOT COVER CAMPER REPAIRS TO BRAKING SYSTEM STATING THAT THE BRAKING SYSTEM WAS NOT PROPERLY MAINTAINED. I DO NOT UNDERSTAND WHAT THE PARKING GEAR FAILING HAS TO DO WITH THE BRAKING SYSTEM OTHER THEN THE EMERGENCY BRAKE IS TIED TO THE
