A vehicle has one or more accelerometers for detecting acceleration of a chassis component. One or more separate sensors are also provided in the vehicle. A controller is programmed to receive a signal indicating acceleration from the one or more accelerometers, wherein the acceleration is between a lower threshold that indicates normal vehicle operation and an upper threshold which would otherwise set off restraint devices, such as airbags for example. When the acceleration is between the thresholds, a potential-chassis-damage signal can be locally created or sent. The controller then validates the potential-chassis-damage signal based on the signals received from the separate sensors. Upon validation, the controller outputs a message to a display, such as a display screen inside the vehicle or an OBD diagnostic tool, warning a user of potential-chassis damage.
