These are reports made to NHTSA, not verified diagnoses. More reports can reflect more vehicles, more time on the road, or greater reporting activity.
The reporting timeline
When reports arrived.
Reports by year filed, not by the year a problem occurred. Showing the latest 15 years with reports.
68,000 miles is the median among 50 reports with usable mileage. The middle half spans 41,400–100,000 miles.
This describes the submitted reports. It does not predict when a vehicle will fail.
02 / Official safety campaigns
4 recall campaigns on file.
A campaign can cover only certain production dates or configurations. The count does not tell you whether an individual car has an open recall.

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

Official inquiries.
An investigation is an inquiry into a potential concern. Its presence does not establish a defect, and a closed case does not certify a car’s condition.
HUMMER H2 STEERING KNUCKLE FAILURESEA05017
ODI UPGRADED THIS INVESTIGATION AT THE CONCLUSION OF PE04-080.THE ALLEGED DEFECT INVOLVES THE FAILURE OF THE STEERING KNUCKLE AT THE LOWER BALL JOINT BOSS, RESULTING IN A SEPARATION OF THE LOWER BALL JOINT FROM THE KNUCKLE.A LOWER BALL JOINT SEPARATION COULD RESULT IN A LOSS OF STEERING AND/OR A DISABLED VEHICLE. IT APPEARS THAT THE FRACTURES OF H2 STEERING KNUCKLES CAN BE ATTRIBUTED TO WHEEL/TIRE COLLISION FORCES BEING TRANSFERRED DIRECTLY TO THE STEERING KNUCKLE.THE ORIGINAL KNUCKLE DESIGN APPEARS TO BE SUFFICIENT FOR THE H2 APPLICATION.EVIDENCE FROM INSPECTED VEHICLES, PHOTOGRAPHS, POLICE REPORTS AND EDR DATA INDICATES COLLISION IMPACT EVENTS PLACED STRESS ON THE STEERING KNUCKLE CAUSING IT TO FRACTURE.FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS WITH REGARD TO THE SUBJECT COMPONENT.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION ON THIS ISSUE IF WARRANTED.
