Forensic Reliability Consultant | Service Operations

Mr. Whitridge analyzes long-term vehicle reliability through the lens of tribology and structural fatigue. He investigates specific failure modes in high-mileage internal combustion and electric drivetrains, focusing on serviceability indices and predictive failure algorithms.

"A vehicle’s true quality isn’t found on the showroom floor, but in the microscopic metal shavings of a high-mileage gearbox. My work is to find where engineering intent meets physical reality, ensuring that reliability is designed in, not just marketed."
