The 1999 E-150 with 4.6L or 5.4L Triton V8s is a workhorse van hampered by catastrophic spark plug ejection issues on the 5.4L, transmission cooler failures, and cruise control deactivation switches that can cause fires. Budget for major engine work if buying high-mileage.
Spark Plug Ejection (5.4L 2-valve Triton)
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Sudden loud pop from engine bay followed by rough idle or misfire, Loss of compression in one cylinder, Metal debris in cylinder from stripped threads, Check engine light with cylinder misfire codes
Fix: The 5.4L 2-valve has notorious weak spark plug threads in aluminum heads. Plugs literally blow out under combustion pressure. Requires HeliCoil or TimeSert thread repair if caught early (2-3 hours), or head removal and machine work if damage is severe (8-12 hours). Some techs preventively install inserts during plug changes. The 4.6L is far less prone but not immune.
Estimated cost: $500-2,500
Transmission Oil Cooler Line Failure
Common · high severity
Typical onset: 90,000-140,000 mi
Symptoms: Transmission fluid leaking near radiator or pooling under front of vehicle, Pink or red fluid mixing with coolant in overflow tank, Transmission slipping or delayed engagement after cooler leak develops, Milky transmission fluid indicating coolant contamination
Fix: Steel cooler lines rust through where they pass along frame rails and connection points fail at crimps. When the internal radiator cooler fails, coolant cross-contaminates transmission fluid destroying the 4R70W/4R100 transmission. Requires cooler line replacement (2 hours) or full radiator if internal cooler compromised. If contamination occurred, transmission flush is mandatory and often a rebuild follows within 10,000 miles (12-16 hours). This is a known fleet-killer.
Estimated cost: $400-4,000
Speed Control Deactivation Switch Fire Risk
Occasional · high severity
Symptoms: Burning smell from brake pedal area, Cruise control inoperative, Smoke from under dash near brake pedal bracket, Brake fluid leaking onto switch (precursor to failure)
Fix: The cruise control deactivation switch on the brake pedal can overheat and catch fire even with vehicle off due to internal short circuit. Ford recalled millions of vehicles for this across multiple years. Switch replacement takes 0.5 hours. Check if recall 05S26 or 06S37 was performed—if not, do it immediately regardless of cruise function. This has burned vehicles to the ground.
Estimated cost: $0-150
Intake Manifold Gasket Failure (4.6L/5.4L)
Common · medium severity
Typical onset: 100,000-160,000 mi
Symptoms: Coolant seeping from front or rear of intake manifold, Slow coolant loss with no visible external leaks, Rough idle or misfire from coolant entering cylinders, White smoke from exhaust on cold start
Fix: Composite intake manifold gaskets deteriorate from heat cycling. Coolant leaks externally down block or internally into cylinders. Requires intake removal, gasket replacement, and often new intake bolts (6-8 hours). The 5.4L is slightly worse due to higher under-hood temps. Aftermarket Fel-Pro gaskets hold up better than OE.
Estimated cost: $800-1,400
Rear Door Latch Failure
Occasional · medium severity
Symptoms: Rear doors will not latch or randomly pop open while driving, Door ajar warning stays illuminated, Excessive force required to close rear doors, Latch mechanism feels loose or rattles
Fix: Door latch pawl springs weaken or break, preventing doors from staying closed. This affects both cargo and passenger vans. Ford recalled some model years (recall 03S17) but not all were covered. Latch assembly replacement per door takes 1.5 hours. Critical safety issue if rear doors open in transit with passengers or cargo.
Estimated cost: $200-350
Fuel Tank Strap Corrosion
Occasional · medium severity
Symptoms: Clunking sound from under vehicle over bumps, Visible surface rust or scaling on metal straps holding tank, Fuel tank hanging lower than normal, Fuel smell from tank shifting against heatshield
Fix: Steel tank straps rust through in salt-belt states, allowing tank to sag or shift. Requires tank lowering and strap replacement (2-3 hours). Inspect during any undercarriage work. Ford issued recall 06S43 for some E-series but coverage was limited. A dropped tank on the highway is catastrophic.
Estimated cost: $300-600
Transmission Mount Collapse
Common · low severity
Typical onset: 80,000-120,000 mi
Symptoms: Clunk when shifting from park to drive or reverse, Excessive vibration at idle in gear, Visible transmission sag when inspected on lift, Harsh engagement into gear
Fix: Rubber transmission mount deteriorates from heat and weight of the 4R70W/4R100. Allows tailhousing to drop and causes driveline angle issues. Replacement takes 1.5 hours with transmission support. Cheap insurance against transmission damage from misalignment. Replace whenever you see tears or fluid saturation in the rubber.
Estimated cost: $200-350
Owner tips
Change spark plugs on 5.4L engines at 60,000 mi MAX using Motorcraft plugs and anti-seize—never let them go to 100k
Inspect transmission cooler lines and radiator for cross-contamination every oil change—this single issue destroys more E-series transmissions than anything else
Verify cruise control deactivation switch recall was completed—check under brake pedal for switch part number or wetness from brake fluid
Use Motorcraft Mercon V fluid only in 4R70W/4R100 transmissions and change at 50,000 mi intervals in van service
Budget $1,500-2,000 reserve for eventual spark plug thread repair on 5.4L—it's not if, but when
Buy a 4.6L example with documented recalls completed and low mileage under $120k; avoid high-mileage 5.4L vans unless engine work is already done or priced in—these are cheap for a reason.

Every control module on the 1997-2003 Ford E-150 — where it lives, replacement time, and what it takes to program a replacement. Modules marked dealer / factory tool won't work after a part swap alone — budget for programming.
⚠️ Not a separate module; requires PCM, cluster, and key programming; minimum 2 programmed keys required to add additional keys; dealer tool required for single-key scenarios

VEHICLE SPEED CONTROL · 07V336000
2007-08-03 · EA05005
ON CERTAIN PICKUP TRUCKS, PASSENGER VEHICLES, SPORT UTILITY VEHICLES, AND MOTOR HOMES CHASSIS, THE SPEED CONTROL DEACTIVATION SWITCH MAY, UNDER CERTAIN CONDITIONS, LEAK INTERNALLY AND THEN OVERHEAT, SMOKE, OR BURN.
Consequence: THIS COULD RESULT IN AN UNDERHOOD FIRE.
Remedy: DEALERS WILL INSTALL A FUSED WIRING HARNESS. OWNERS OF THE PASSENGER CARS INCLUDED IN THIS CAMPAIGN WILL BE INSTRUCTED TO RETURN THEIR VEHICLES TO THEIR DEALERS TO HAVE THE SPEED CONTROL DEACTIVATION SWITCH DISCONNECTED AS AN INTERIM REPAIR. AS SOON AS REPAIR PARTS ARE AVAILABLE (EXPECTED OCTOBER 2007), OWNERS WILL BE INSTRUCTED TO RETURN TO THE DEALERS FOR INSTALLATION OF A FUSED WIRING HARNESS. THE RECALL BEGAN ON AUGUST 13, 2007, AND MAILING COMPLETED BY SEPTEMBER 19, 2007. OWNERS MAY CONTACT FORD AT 1-888-222-2751.
VEHICLE DESCRIPTION: ON CERTAIN VANS WITH AMBULANCE PREP PACKAGES OR OTHER SEVERE-DUTY APPLICATIONS INVOLVING OPERATION AT OR NEAR THE GROSS VEHICLE WEIGHT WITH FREQUENT TWISTING OF THE VEHICLE BODY, SUCH AS OFF-ROAD, ROUGH ROAD OR SPEED BUMP EVENTS, THE 35 GALLON MID-SHIP FUEL TANK COULD DEVELOP A CRACK WHERE IT CONTACTS THE FRAME CROSS MEMBER. IF THE FUEL TANK CRACKS, FUEL LEAKAGE COULD OCCUR.
Consequence: FUEL LEAKAGE IN THE PRESENCE OF AN IGNITION SOURCE COULD RESULT IN A FIRE.
Remedy: DEALERS WILL INSPECT THE FUEL TANK AND, IF CRACKED, WILL REPLACE THE TANK. INSULATOR PADS WILL BE INSTALLED ON ALL VEHICLES TO REDUCE THE STRESS LEVELS IN THE FUEL TANK. OWNER NOTIFICATION BEGAN APRIL 19, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT FORD AT 1-800-392-3673.
