While driving at 45 mph in heavy traffic, your truck suddenly lost engine power and slowed down abruptly, forcing other vehicles to brake and swerve to avoid you. OnStar diagnostics confirmed a problem with the engine control module or transmission control system, but your GM dealer hasn't yet pinpointed the exact issue. The fix will likely involve diagnosing and repairing or replacing the faulty engine control module, transmission control module, or transmission range sensor.
