Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners of the 2011 Ford F-350 diesel report multiple engine failures, with the EGT (exhaust gas temperature) sensor dominating the complaint pattern. The sensor defect triggers a dash warning ("pull over immediately" or "stop safely now"), then shuts down the engine within seconds, killing power steering and all auxiliaries—a terrifying scenario on a busy highway. Owners replaced the sensor at costs of $100–$600, but Ford denied warranty coverage on non-ambulance F350s despite issuing recall 13V535000 for identical failures on ambulance-chassis trucks built during the same period. Ford later issued recall 14E03 in January 2015, but owners report Ford still refused reimbursement.
Beyond the EGT sensor, owners describe stalling events—engine shutting down mid-drive with no warning, sometimes restarting instantly, sometimes requiring 2–20 minutes of waiting. Dealers could not diagnose or fix these recurring shutdowns. One owner had the entire fuel pump and fuel system replaced, only to experience catastrophic internal engine damage with metal shavings found throughout the block; his warranty claim has been pending unapproved for eight weeks. Another owner had glow plugs fracture inside the engine at 170,000 miles, requiring complete engine replacement. A check-engine light that stayed on continuously generated different fault codes on each scan, and the manufacturer offered only promises of future software fixes, leaving the truck unrepaired. Owners report reading numerous internet posts describing 2011 diesel engines "exploding," suggesting this is a pattern Ford has not adequately addressed.

Failure modes owners describe
EGT Exhaust Gas Temperature Sensor Failure
Faulty EGT sensor triggers limp-mode shutdown with dash warning 'shutting down,' complete engine shutdown within seconds, loss of power steering and auxiliary systems. Sensor failures cascade from a manufacturing defect affecting sensors built during a specific timeframe. Ford issued recall 13V535000 for ambulance-chassis F350/450/550 models with identical symptoms but refused to acknowledge the same defect in non-ambulance F350s.
When: 2013 model year; incidents reported at 4,000–62,363 miles; first incident reported 08/29/2013
Symptoms owners cite: Dashboard warning message 'pulling over immediately' or 'stop safely now'; Engine shutdown within 10–30 seconds of warning; Complete loss of power steering; Complete loss of auxiliary power systems; Difficulty restarting; requires waiting 45 minutes to 2–20 minutes before restart
Codes mentioned: EGT sensor fault codes (unspecified), Check engine light (various codes per narrative 6)
Repairs/costs cited: EGT sensor replacement; costs reported $100–$600 depending on dealer. Ford denied warranty coverage on non-ambulance models, citing sensor as non-powertrain component.
Recalls/TSBs owners mention: Recall 13V535000 issued November 2013 limited to ambulance-chassis F350/450/550 models. Recall 14E03 issued January 2015 (also involving EGT sensor). Ford refused reimbursement and warranty coverage for private-use F350s built during same production run.
Diesel Exhaust Fluid Pump Failure
DEF pump failure causes sudden loss of engine power and check engine light illumination while driving at highway speed. Dealer diagnosed the pump as defective but repair not completed per narrative.
When: ~62,363 miles
Symptoms owners cite: Sudden loss of engine power while driving 60 mph; Check engine warning light illumination
Codes mentioned: DEF pump fault (unspecified code)
Repairs/costs cited: Diesel Exhaust Fluid pump replacement required; cost not stated. Vehicle not repaired per narrative.
Recalls/TSBs owners mention: Manufacturer notified; no response documented.
Engine Stall – Undiagnosed Root Cause
Engine shuts down without warning during highway driving, sometimes restarts immediately, sometimes requires extended wait time. Multiple dealer visits and diagnostic attempts failed to identify root cause or implement repair. Owner suspects EGR system involvement. No fault codes displayed on vehicle computer screen in one case.
When: 59,800 miles; recurring over one-month period (4 incidents); other incident at unspecified mileage
Symptoms owners cite: Engine shut-down without warning while driving; Intermittent no-start condition; Vehicle restart after 2–20 minute wait or spontaneous restart; No diagnostic codes visible to owner
Codes mentioned: None retrieved or displayed
Repairs/costs cited: Dealer unable to diagnose or repair; repair not completed.
Recalls/TSBs owners mention: Not notified per narrative 8; narrative 9 references common internet complaints suggesting widespread issue.
Glow Plug Fracture
Glow plugs fractured internally within the engine block, forcing engine replacement. Failure occurred at high mileage (170,000 miles) without prior warning.
When: ~170,000 miles
Symptoms owners cite: Engine shut-off while driving at 60 mph
Codes mentioned: None specified
Repairs/costs cited: Complete engine replacement performed by independent mechanic.
Recalls/TSBs owners mention: Manufacturer notified; no response documented.
Fuel Pump and Internal Engine Damage – Metal Shavings
Fuel pump failure requiring replacement of entire fuel system. Subsequently, internal engine damage occurred with metal shavings distributed throughout engine block ('something internally blown up'). Extended warranty claim pending for 8 weeks without approval.
When: 65,000 miles on first failure; internal engine damage failure mileage unstated
Symptoms owners cite: Engine malfunction leaving driver stranded; Recurrence of major engine malfunction within short timeframe; Evidence of internal metal debris
Codes mentioned: None specified
Repairs/costs cited: Fuel pump and fuel system replacement completed; internal engine damage repair pending; previous repair took 2+ months. Owner reports reading multiple online posts describing 2011 diesel engines 'exploding.'
Recalls/TSBs owners mention: Ford extended warranty claim pending 8 weeks without approval; owner reports Ford refusing coverage in similar cases.
Check Engine Light – Intermittent Multiple Fault Codes
Check engine light illuminated continuously; multiple diagnostic scans returned different fault codes each time. Dealer attributed issue to pending software calibration updates; no repairs made. Manufacturer claimed to be working on new calibrations but vehicle remained unrepaired.
When: 4,000–8,500 miles
Symptoms owners cite: Continuously illuminated check engine light; Different fault codes on repeated diagnostic scans
Codes mentioned: Multiple codes reported; specific codes not documented
Repairs/costs cited: No repair completed; vehicle left in unresolved state.

I was passing a transport truck and just as I got even with the door of the truck my Ford f350 super duty motor quit, just shut down. A bus was coming in my lane as I was passing, the truck slowed down to let me by but I had no power, no power brakes or power steering. The bus slowed down and I braked enough to get in back of the truck and over to the side of the road. The bus went on by and the…
