2004 Ford F-350: sudden loss of power

Filed Apr 28, 2022 · Engine · HI

While driving at 40-50 MPH the vehicle will lose power and then then stalls while moving leading to loss of power. The loss power of affects the power steering posing a direct threat for an auto collision due to the difficult in steering the moving vehicle into an emergency lane. Avoided several accidents with this truck. Once it is stalled it can take numerous times to restart the vehicle. This issue seems to occur more on slopes going up hill. This does not seem to occur as often going downhill or on areas with no incline. Currently vehicle has 126,931.8 miles on it. Regularly serviced and otherwise running fine.

Engine began bucking, sudden power loss and power steering and power brake loss. Mechanic conclusion was that the lining of the fuel tank had dislodged and caused the engine to foul, causing a sudden power loss. Dealer said they had never heard of the problem but we later learned they were very familiar with it, had done dozens of repairs (replacement of tank with poly tank) and that a "secret" repair bulletin had been issued ty ford to all dealers. This issue is now the subject of a class action lawsuit in new jersey. Google "ford fuel tank lining" for more info on the suit, but by not issuing a recall this issue is a potential safety concern. Had we been in heavier traffic and unable to get the vehicle to the side of the road there may have been a serious accident.

My 2004 ford f-350 6.0 diesel. Hesitate or surges while driving, and/or the engine may stall while driving at all speeds including highway speed, will lose power steering and brakes and when at a stop it will lunge forward. The engine may or may not restart after stall. I feel that this is a great safety concern I have almost lost control of my vehicle on a few occasions while towing my boat and going around corners. I have heard of other people having the same problems with their 2004 6.0 diesels. Please help!

On 01-06-2008 I started to have significant problems with my 2004 ford f-350. It has just over 41,000 miles on it. It was smoking and had significant loss of power problems while at low road speed. Problem would clear once truck was >40 MPH in speed. Took it to local ford dealer on 01-07-2008. Their investigation showed that the egr valve was sticking. The valve assembly had to be replaced. The service person stated that this problem is common enough that they are keeping a couple of extra egr valve assemblies in their stock room. I asked if there was any indication of a product recall in the works. He said that he did not know of one but that one might happen in the near future and that I should keep my invoice just in case. My question/concern(s) is this: how often or frequent should an egr valve stick and/or fail? If their failure rate is high (1 failure per vehicle every 50,000 or less) then shouldn't there be a redesign and recall to improve the performance and safety?

Dt*: the contact stated upon starting the vehicle the oil pressure dropped and the engine died. The vehicle was towed to an independent repair shop where it was determined the oil pump and the lower intake manifold gaskets failed. The oil pump is made of aluminum which influenced the integrity of the pump, and caused the pump to wear out prematurely. The dealer was alerted of the problem, prior to the independent repair shop making the repair. Updated 5/10/2006 - the vehicle leaked coolant which caused the vehicle to overheat but the temp gauge did not indicate that the vehicle was overheating. The coolant also flowed through the egr valve which caused lose of power.

When truck originally purchased bubble on tire, and dealer said they all come that way, tire went flat while parked about a month later, no holes, we were told tire was no good, had to be replaced. Truck kept stalling, loss of brakes and steering while navigating downhill, solenoid assembly replaced. 2 days later kept stalling. Dealer had truck 21 days to rebuild transmission, again solenoid assembly replaced after that replaced wiring harness. Since then, caliper broke and brakes went, turbo has been replaced. Vehicle has repeatedly stalled, noises from rear end with no dx. Now engine smoking, loss of power, rpms jump while idling. Truck has also repeatedly changed gears automatically, ie while at red light truck would jump to 3rd and then truck would stall.
