2003 Ford Ranger Problems

What owners report

Owners of the 2003 Ford Ranger most often write about two very different things: rear-frame and underbody rust that appears well before the truck's age would suggest, and unexpected engine revving or surging that comes on while braking at low speed. Brake complaints (pulsation, fading, rear lock-up in wet weather) and an airbag warning light that stays on are also common, and many of these reports come in at moderate mileage on otherwise well-kept trucks.

1. 1
   Body and structure

   Rear frame and underbody rust-through

   • 58 complaints (24%)
   • median 81,500 mi at 12.4 yrs old (45 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2003–2023

   Complaints describe rear frame rails, spring mounts, the spare-tire carrier and fuel-tank hanger rusting through while the body still looks presentable. Owners report crunching or rattling noises, spring brackets breaking loose, and in several cases the spare tire dropping onto the road. Some were told by shops or dealers that the frame was too far gone to repair or would not pass inspection. Usually reported between roughly 48,000 and 150,000 miles, frequently on trucks used in winter-salt areas.

   What to check: Put the truck on a lift or crawl underneath and probe the rear frame rails, spring shackles, spare-tire carrier and fuel-tank straps with a screwdriver; a solid-looking body can hide a rotted frame. Ask whether any frame or bracket repair has already been done.

   Vehicle speed control

   Engine revs or surges while braking at low speed

   • 88 complaints (36%)
   • median 51,000 mi at 6.0 yrs old (67 state mileage)
   • 17 mention a crash, fire or injury
   • filed 2003–2023

   Owners describe the engine climbing to 2,000-4,000 rpm on its own when they press the brake to stop, sometimes with the tires chirping or the truck creeping forward. Several say the condition stops after shifting to neutral or restarting the engine. According to the complaints, dealers often could not duplicate it; a few replaced the throttle body or reprogrammed the computer without a lasting result. Reported from very low mileage (under 1,000 miles) up to about 140,000 miles, usually at stops, in traffic, or when shifting into reverse.

   Recall 09V399000

   What to check: Drive the truck through several stop-and-go cycles and note whether idle speed jumps when you brake; also ask whether the speed-control deactivation switch recall work (09V399000) was completed, since that recall covers a different speed-control part.

   “As I slowly pulled my 2003 Ford Ranger into a parking space at work this morning with my foot on the brake the truck suddenly accelerated. I applied the brake harder and the truck stopped. I verified that I did not have my foot on both the brake and accelerator, only on the brake.”

   NHTSA complaint #10359971, filed 2010-10, 96,500 miles

   “I have a 2003 Ford Ranger, when I apply the brakes the vehicle surges. Forward; I put the truck in park & shut off the ignition. When I restart. It returns to normal. This happens on once in a while.”

   Air bags

   Airbag warning light stays on

   • 25 complaints (10%)
   • median 46,800 mi at 5.0 yrs old (17 state mileage)
   • 11 mention a crash, fire or injury
   • filed 2003–2023

   Owners report the airbag light coming on and staying lit while driving, sometimes after only a few thousand miles. Complaints mention repeat dealer visits, a chafed wire or rivet rubbing the airbag wiring under the carpet, and a faulty front sensor in one case. A few owners also describe bags that did not deploy in a collision, or deployed without an impact. Reported from roughly 4,000 to 80,000 miles, often noticed shortly after purchase or during routine driving.

   What to check: Turn the key to the run position and confirm the airbag light goes out after the bulb check; ask whether any airbag recall or wiring repair has been completed and request documentation.

   “Tacata recall airbag light is flashing the stays on .not sure what is causing it but it could be serious if the bags do not work when needed . It came on about 1 month ago.

   Brakes

   Front brake pulsation, fade and rear lock-up

   • 24 complaints (10%)
   • median 55,000 mi at 4.1 yrs old (19 state mileage)
   • 5 mention a crash, fire or injury
   • filed 2003–2013

   Complaints describe vibration through the steering wheel when braking, attributed to warped front rotors, with some owners on their second or third set. Others report the pedal sinking toward the floor at low speed, and a few describe the rear brakes locking in wet weather and causing a skid. Dealers reportedly turned or replaced rotors and rear brake parts, and one owner was told the wet-weather lock-up was moisture-related. Mostly reported between about 20,000 and 100,000 miles, with the wet-weather lock-up noted after rain.

   1 related service bulletin

   What to check: Brake firmly from highway speed on a test drive and feel for pulsation or a pedal that sinks; ask for brake service records, and check whether the rear drum brake service bulletin (10011169) work was performed.

   “This problem has appeared all of a sudden without warning. Brakes fade at low speeds. The pedal sinks to the floorboard. This condition occurs randomly. I have topped off the brake fluid reservoir. This has not changed the situation. I've reviewed the internet for potential remedies and have discovered many others with the same or similar problem.”

   NHTSA complaint #10392991, filed 2011-03, 98,000 miles

   “Brake pedal and accelerator pedal toooo close together! Distance of 2 & 1/4 causes contact with accelerator when brake is being applied numerous incidents since purchased vehicle in 03.. I wear a size 9 &1/2 to a 10 & 1/2 size shoe. Even though I am aware of the problem, I find that it keeps happening repeatedly; but I only bumped a curb once with my tires.”

   Fuel system

   Fuel pump cutoff switch tripped by passengers

   • 10 complaints (4%)
   • median 45,891 mi at 3.6 yrs old (9 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 2004–2013

   Complaints describe the inertia fuel cutoff switch on the passenger-side kick panel being knocked or disconnected by a passenger's foot, which cuts the engine and leaves the truck unable to restart until the switch is reset. Owners report this happening repeatedly, sometimes in traffic, and say dealers offered little beyond explaining the switch's location. Typically reported at low to moderate mileage, often on trucks with frequent passenger use.

   What to check: Locate the cutoff switch on the passenger-side kick panel, check that its connector is fully seated, and ask whether it has ever tripped unexpectedly; know how to reset it before you need to.

   “I have a 2003 Ford Ranger regular cab 2 wheel drive truck. On 5 occasions the emergency fuel shutoff switch located inside the cab on the passenger side fire wall has been dislodge by the passenger getting there foot on the connector and disconnecting the power plug from the switch this causes the truck to stall immediately. I have only owned this truck for approx 90 days. If this happens at the wrong time this could get someone hurt or killed.”

   NHTSA complaint #10130122, filed 2005-07, 58,000 miles

   “While driving north on I-17 headed to flagstaff, az, at 60+ MPH, the engine on my 2003 Ford Ranger suddenly cut out without any warning. This caused me to have to navigate my vehicle from the left lane over to the right shoulder of the highway without the benefit of power steering or any engine power. Fortunately, I was able to get onto the shoulder without incident or injury. If the highway had been more crowed this could have LED to an accident. …”

Buying note. Inspect the frame and underbody carefully before buying, since rust-through is the most frequently reported problem and can end a truck's useful life early. On the test drive, watch idle speed during stops and check brake feel and the airbag light, then ask for service records covering recalls and the brake service bulletin.
