1994 Ford F-350 Problems

What owners report

Owners of this model year most often describe brake problems: a pedal that sinks or goes to the floor, rear-wheel lockup, and braking that feels weak, often while towing or on hills. Transmission and clutch complaints are the next most common theme, including repeated clutch slave cylinder failures and transmission work, followed by engine-compartment fires traced to the cruise control deactivation switch and by fuel and cooling-system leaks reported at higher mileages.

1. 1
   Brakes

   Brake pedal sinks or brakes fail to stop the truck

   • 22 complaints (23%)
   • median 212,000 mi at 10.6 yrs old (2 state mileage, few)
   • filed 1995–2005

   Complaints describe a pedal that drops toward the floor, sometimes randomly and sometimes when towing a trailer or camper, with the truck continuing to roll or failing to slow. Several report rear wheels locking and the vehicle sliding or losing control. Owners say master cylinders, rear drums and lines were replaced, sometimes more than once, without fully resolving the problem; one complaint notes a hole in the rear brake line where it was clamped to the frame. Reports span a wide mileage range, from vehicles with no mileage given to one at about 299,000 miles; several involve towing or downhill driving.

   Recall 94V169001

   What to check: Test the pedal for a slow sink while holding firm pressure at a stop, and have the brake lines, rear drums and parking brake inspected. Ask for service records showing whether the master cylinder or rear brake components have been replaced.

   “While pulling a trailer loaded with fire wood, the brakes failed at an intersection. The brake pedal went nearly to the floor. The brakes would not slow me down. The emergency brake was not stong enough to stop me while loaded. Had to down shift to stop. The brake line going to the rear axle had a hole in it. The hole was located at one on clamps to the frame.”

   NHTSA complaint #10061915, filed 2004-03, 125,000 miles

   “Brake fade. When at a complete stop, pedal will sink slowly but not enough to active a warning light. If pedal is not pressed harder vehicle will roll. Dealership says this is not the first vehicle to do this and has contacted the manufacturer. Vehicle still does it to this day. Master cylinder has been replaced twice, still not fixed.”

   Transmission and drivetrain

   Clutch and transmission failures, including slave cylinder

   • 15 complaints (16%)
   • median 145,900 mi at 14.0 yrs old (1 states mileage, few)
   • filed 1995–2007

   Owners describe clutch slave cylinders cracking and leaking fluid repeatedly, in some cases several times over a few years, and a clutch pedal that falls to the floor with no power to the wheels. Others report automatic transmission failures, transmission fluid boiling out of the dipstick tube onto the exhaust, and torque converter or sensor replacements. Some say the dealer treated the repeated failures as normal wear. Mostly reported on trucks with no mileage stated or past 100,000 miles; one transmission failure was reported at about 145,900 miles.

   What to check: Check for fluid weeping around the clutch slave cylinder and the area where the engine meets the transmission, and ask whether the slave cylinder has been replaced. On automatics, check fluid condition and smell and ask about prior transmission repairs.

   2 excerpts from owner complaints in NHTSA records

   “Clutch slave cylinder keeps failing cracking leaking fluid at least once if not twice per year Ford motor company has told me tough luck on the repairs the last time they had made a new style slave cylinder to cure the problem but it failed again today driving in city traffic. It is extremly hard to stop without a clutch”

   NHTSA complaint #701528, filed 1998-12

   “Purchase this vehicle new in dec. Of 1993 and have had 7 transmission failures. Some of these failures have created situations of transmsission fluid boiling out of dipstick tube and dropping down on exhaust. Very good potential for oil fire when transmission fluid boiled out and vehicle was smoking from fluid dropping on exhaust. Have checked with atra {automatic transmission rebuilders association} and they have concluded that this particular transmission{e4od} has been very troublesome with high failure rate. …”

   Vehicle speed control

   Underhood fires traced to the cruise control switch

   • 5 complaints (5%)
   • median 189,500 mi at 13.2 yrs old (2 state mileage, few)
   • 4 mention a crash, fire or injury
   • filed 2005–2023

   Complaints describe smoke or fire in the engine compartment on the driver's side, sometimes while the truck was parked for days, with the cruise control deactivation switch identified as the origin. In one case the owner disconnected the cruise control wiring and the smoke stopped. Recall notices were received for related vehicles but not this one in some reports, and one owner notes the recall repair part was unavailable. Reported across a wide mileage range, from about 150,000 miles to over 229,000 miles, and in one case after the truck had sat unused for several days.

   Recall 06V286000Recall 94V101000

   What to check: Ask whether the speed control deactivation switch has been replaced under recall, and have the switch and its connector inspected for heat damage or fluid contamination.

   “Our 1994 Ford F-350 was destroyed by fire originating at the master cylinder today. There was a small brake fluid leak noticed in this area the other day; but I was unaware of the cruise control shutoff switch danger until after the fire. I have received no notice of a recall for this vehicle.”

   NHTSA complaint #10128245, filed 2005-07

   “F350 Ford supercrew 4x4 7.3 turbo diesel had been sitting for 4 days. Wife comes out of house finds truck on fire in engine compartment on driver's side. The cruise deactivation switch was disconnected.”

   Fuel system

   Fuel and oil leaks from the tank, filter housing and engine

   • 5 complaints (5%)
   • median 118,500 mi at 10.5 yrs old (2 state mileage, few)
   • filed 1999–2004

   Owners report cracks in the fuel tank and pinholes in the fuel filter housing that leak fuel onto the engine, with the dealer recommending replacement. One describes fuel transferring between tanks on a dual-tank truck and overflowing at the filler cap. Another describes an engine failure following an oil capacity change to the dipstick that the owner was not told about. Reported between roughly 14,000 and 137,000 miles, with no clear seasonal pattern in the sample.

   What to check: Look for fuel smell or staining around the filter housing, tank seams and filler neck, and confirm the correct dipstick and oil capacity for the engine.

   “The fuel injector pump for my 1994 Ford f350 pickup truck has failed for the ofurth time in four years. The engine is a navistar 7.3 liter turbo diesel. I have researched the issue on the internet and found that this engine has a problem with the tolerances for the cam, whch damages the pump.”

   NHTSA complaint #10031174, filed 2003-08, 100,000 miles

   “Cracks have accumulated on the fuel tank, causing fuel to leak. Dealership was notified, but did not resolve the problem. . Sime vehicles can experience a cross tank fuel condition due to adamaged valve in the fuel pump/sender assembly. Fuel may besupplied from one tank and some or all of the unused fuel may be returned to the other tank. Should this occur, the capacity of the receiving tank may overflow the filler cap.”

   Engine cooling

   Accessory belt and pulley failures leading to loss of assist

   • 9 complaints (9%)
   • typically at 3.1 yrs old
   • filed 1995–2000

   Complaints describe the tensioner pulley bracket failing and throwing the accessory belt, which leaves the truck without power steering and other belt-driven assist. Owners report the same repair multiple times within months, and say the manufacturer acknowledged a bracket and belt-length change but did not cover all the costs. Reported after roughly 15,000 miles per failure, with repeat failures within about six months.

   What to check: Inspect the belt, tensioner and bracket for wear or misalignment, and ask whether the updated bracket and longer belt have been fitted.

   2 excerpts from owner complaints in NHTSA records

   “Third time problem accurred/repaired in last 11 months. Ford acknowledges problem with bracket assembly to which tensioner pulley is attached; also notes belt length has been changed to a longer version. Inspite of acknowledgement, Ford will not cover all costs associated with recurring repair, either current or past. Net cost of previous repairs: approx. $600; both failed at under approx 6 months, both with approx 15k miles. Current repair cost: $approx $850. …”

   NHTSA complaint #714708, filed 1999-11

   “Exhaust manifold bolt broke, causing the exhaust to leak, which may cause a fire. Dealer was not willing to help, wont cover repairs under their warranty. Please provide further information.”

   NHTSA complaint #858291, filed 2000-03

Buying note. These are high-mileage trucks, so a careful inspection of the brake system, clutch hydraulics and transmission matters more than service records alone. Ask specifically whether the speed-control switch recall was performed and whether any brake or clutch repairs have been repeated.
