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.
90,000 miles is the median among 383 reports with usable mileage. The middle half spans 57,154–120,200 miles.
This describes the submitted reports. It does not predict when a vehicle will fail.

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.
