Engine & Drivetrain Failures

Engine failures, transmission malfunctions, and drivetrain defects can cause a truck to lose power, stall on highways, or accelerate uncontrollably. Turbocharger failures, coolant leaks, broken driveshafts, and throttle malfunctions are among the most common mechanical causes of loss-of-control crashes. Many of these failures leave physical evidence that investigators can trace back to deferred maintenance or ignored warning signs.
