1997 Ford F-150 Problems

What owners report

Owners of this model year most often describe two things: fuel tank straps rusting through so the tank drops or leaks, and 4.2L V6 engines losing coolant internally and then failing. Many of the 4.2L reports land between roughly 50,000 and 120,000 miles, while the strap complaints cluster at higher mileage on trucks in rust-belt states. A separate, high-mileage theme is fire starting at the cruise control switch on parked trucks.

1. 1
   Engine cooling

   4.2L V6 coolant leak and engine failure

   • 343 complaints (12%)
   • median 97,807 mi at 8.9 yrs old (231 state mileage)
   • 7 mention a crash, fire or injury
   • owner-quoted repair $3,500 (median of 73 quotes)
   • filed 1997–2016

   Owners of 4.2L V6 trucks report gradual coolant loss with no obvious external leak, sometimes white smoke from the exhaust or water found in the oil pan, followed by loud knocking and a locked or thrown-rod engine. Several say the engine had to be replaced at their own expense, and that the dealer or manufacturer did not offer help once the truck was out of warranty. Some note the same failure happening again on a replacement engine. Reported from roughly 50,000 to 160,000 miles, with several failures noted near 70,000 to 100,000 miles.

   What to check: On a 4.2L truck, check the coolant level and look for white residue or staining at the intake manifold gasket area, and watch for white exhaust smoke on start-up. Ask whether the intake gaskets or engine have been replaced and keep receipts.

   “I have 1997 Ford f150 4.2l pick-up that has the famos anti freeze internal leak that has ruined my motor. I have 56,000mi on it, and feel Ford has sold millions of these lemons and are doing nothing about it! Is there any hope for us who got screwed?”

   NHTSA complaint #10121937, filed 2005-05, 56,000 miles

   “Ford F-150 complaint on 4.2l /v6 engine. Engine had total failure at 69k due to engine coolant leak into motor. I never received any recall notices for gasket problem noted in owner notification bulletins and technical service bulletins issued by Ford. This is a major problem due to poorly engineered faulty parts used by Ford in this motor. This is a major problem and all v6 F-150 owners should be compensated for damages by Ford. I need to pay four thousand dollars to replace the engine.”

   Fuel system

   Fuel tank straps rust out and tank drops

   • 205 complaints (7%)
   • median 140,000 mi at 14.6 yrs old (169 state mileage)
   • 4 mention a crash, fire or injury
   • owner-quoted repair $595 (median of 10 quotes)
   • filed 1998–2023

   Owners describe a loud clunk or scraping noise while driving, then finding the fuel tank hanging or dragging on the road, held by the fuel lines or nothing at all. Inspection usually shows one or both steel straps rusted through; in some cases the tank, filler neck or lines are damaged and fuel spills. Complaints describe the dealer declining work once the truck is old or heavily rusted, and some owners report the problem returning or a leak appearing shortly after recall work was done. Mostly reported between roughly 100,000 and 180,000 miles on trucks with visible underbody corrosion, often in states that use road salt.

   Recall 11V385000Recall 98V1610004 related service bulletins

   What to check: Look under the truck at both tank straps for heavy rust, scale or thin spots, and check the tank sits tight with no fuel smell or fresh drip. Ask whether recall 11S21 (tank strap replacement) was performed and get it in writing.

   “We were driving down the road at about 25 MPH after we decided not to take the freeway to get to our destination. We heard a huge clunk/drop noise and severe scraping sound so we pulled off immediately to find that the gas tank in our 1997 Ford F-150 had fallen and was dragging on the ground. The strap(s) had apparently rusted off. The truck was towed to a local Ford dealership where the work will be done on monday. …”

   NHTSA complaint #10407356, filed 2011-06, 178,000 miles

   “I have a 1997 Ford F-150 truck. The gas tank strap rusted through and needed to be replaced last september, 2010. I caught it in time. No accident occurred and the gas tank did not drop. However, if there is a recall, will I be reimbursed for the cost of this repair by Ford?”

   Vehicle speed control

   Parked-truck fires traced to cruise control switch

   • 227 complaints (8%)
   • median 120,000 mi at 8.5 yrs old (153 state mileage)
   • 200 mention a crash, fire or injury
   • owner-quoted repair $1,200 (median of 7 quotes)
   • filed 1997–2023

   Owners describe trucks catching fire while parked and unattended, sometimes hours after the last drive, with flames starting on the driver's side under the hood at the speed control deactivation switch. Several note the cruise control had stopped working or a fuse kept blowing beforehand, and some say the truck was a total loss. Complaints also mention cruise control that would not disengage or engines that idled high afterwards. Reported from about 60,000 to 160,000 miles, with fires occurring while the vehicle was parked rather than in use.

   Recall 05V388000Recall 96V251000

   What to check: Ask whether the speed control deactivation switch recall (05V388000) was completed and whether the switch or its harness has been replaced; a seller report is not enough, so check for a repair receipt or have the switch inspected.

   “On march 7th at 3 am in the morning my 1997 Ford F-150 burst into flames while it was parked in my garage. The truck had not been driven in 12 hours. I was awoken by two loud booms at 3 am. I checked my house (brand new house 1.5 years old) and there were no problems noted. I opened the door leading from the house to the garage, the f150 was totally engulfed in flames. My house was totally destroyed by the ensuing fire.”

   NHTSA complaint #10117989, filed 2005-04, 91,000 miles

   “My 1997 F-150 caught fire while parked in my driveway. This vehicle was not driven in 18 hours. My twelve year old daughter and a neighbor put the fire out. In speaking with Ford motor company they have a recall on cruise control deactivation switches but until today it did not go back to my year model. Due to a television broadcast on friday, august 12, 2005 Ford has now included vehicles up to 1995 however when I spoke with them today they advised it only includes vehicles manufactured at particular plants which does not include my vehicle. …”

   Steering

   Steering shaft separates from the steering gear

   • 194 complaints (7%)
   • median 107,076 mi at 8.3 yrs old (55 state mileage)
   • 25 mention a crash, fire or injury
   • filed 1996–2023

   Owners report the steering wheel suddenly spinning free with no response at low speeds, often while reversing or turning out of a driveway, and mechanics finding the intermediate shaft separated from the steering gear or the mounting bolts broken. Several mention a loose or cracked steering column area beforehand, and some say the repair was welding or replacing the shaft or bolt. Mostly reported between roughly 90,000 and 200,000 miles, often at low-speed maneuvering.

   Recall 03V196000

   What to check: With the engine off, turn the wheel and watch and feel for play between the column shaft and the steering gear; check the coupling and its bolt for looseness, wear or rust. Ask whether recall 03V196000 applied to this VIN and was completed.

   “While shifting into reverse vehicle failed to move. Consumer got out of the vehicle to inspect it, and noticed that both front driver side and passenger side tires were turn inward. Consumer had the vehicle towed to a repair shop for inspection and the mechanic determined that both inner tire rods had popped and needed to be replaced.”

   NHTSA complaint #10083580, filed 2004-08, 88,930 miles

   “Broken bolts to the steering box. No incident involved. Steering control became loose. Diagnosis of problem was a loose steering box from bolt failure. Additional failures of remaining bolts would cause loss of steering control.”

   • median 88,500 mi at 8.6 yrs old (44 state mileage)
   • 37 mention a crash, fire or injury
   • filed 1996–2023

   Owners describe the brake pedal going to the floor with little warning, requiring them to shift to neutral and use the parking brake to stop, and shops finding corroded, ruptured brake lines. Other complaints mention skidding or loss of control on wet pavement and a master cylinder area fire in a parked truck. Reported from roughly 85,000 to 185,000 miles on older trucks, often in rust-prone areas.

   Recall 96V184000

   What to check: Inspect the steel brake lines along the frame for rust and seepage, check the master cylinder and fluid level, and ask when the lines, hoses and fluid were last serviced.

   “I was on my way to work the morning before thanksgiving. I shifted from 2nd to 3rd gear and the back tires hit a patch of water and I started fishtailing. I went off the road and hit a patch of oak trees. One head on. On impact, the seatbelt did not retract and I hit the steering wheel, the dash broke apart and the entire steering column moved with me and I hit the windshield. After hitting the windshield, then the airbag deployed. When the dash broke apart from the steering column moving, it cut my shin which required stitches. …”

   NHTSA complaint #11297409, filed 2020-01, 104,000 miles

   “The vehicle was parked for about a hour when it caught on fire. The consumer extinguished the fire with water hose. The fire started at the master cylinder which was replaced. A couple of weeks later the cruise control stop working.”

   NHTSA complaint #10119119, filed 2005-05, 112,000 miles

Buying note. Inspect the frame and fuel tank straps for rust before anything else, then confirm the tank strap and cruise control switch recalls were completed on this specific VIN. On a 4.2L V6, coolant level and exhaust smoke are worth checking closely, and a pre-purchase inspection by an independent shop is worthwhile on a truck of this age.
