Vehicle has a cp4 fuel pump. This pump has a high failure rate. Upon failure the vehicle shuts down and cannot be restarted. This can happen at any time and anywhere. Can happen while on a highway or freeway. This vehicle is used to haul heave loads. This failure can ending up to $10,000 or more to repair. This failure has not happened on this vehicle yet. Am very concerned about me safety and the safety of others because of the high failure rate.

While driving white smoke bellowing out front right tire wheel well. Upon inspection, smoke coming from exhaust pipe clamp near turbo. Smell so bad have to drive with window open. It appears engine on fire from the amount of smoke emitting from under the hood. At idle it get worse. It appears smoke is exhaust fumes leaking from the pipe joint. No engine light to indicate a problem.
