2005 Ford 500 Problems

What owners report

Owners of the 2005 Ford Five Hundred most often describe throttle-body problems: intermittent idle surging, loss of accelerator response, and the vehicle dropping into "failsafe engine mode" or stalling, which several report happening in traffic or at highway speed. Transmission complaints are nearly as common, typically harsh or delayed shifting, sudden neutral, or loss of drive, and a smaller but recurring group involves instrument-cluster and gauge failures. Most of these reports come in at well over 100,000 miles, so a used example's service history and current drivability matter more than the model year alone.

1. 1
   Vehicle speed control

   Throttle body surging, no throttle response, failsafe mode

   • 50 complaints (51%)
   • median 127,000 mi at 9.7 yrs old (45 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2012–2019

   Complaints describe idle RPM surging that feels like the car is trying to take off, especially at low speed, while parking, or when pulling away from a stop. Other reports describe the accelerator going dead, a sudden lurch or jerk, the wrench or check-engine light coming on, and the message board reading "failsafe engine mode" — sometimes with the engine stalling in traffic or on the highway. Several owners say a dealer cleaned or replaced the throttle body, and some say a throttle-body cleaning or reprogramming did not end the symptoms; a few report dealers unable to reproduce the fault. Reported across a wide mileage range, from roughly 50,000 to over 200,000 miles, with many at 100,000 or more; often intermittent and at low speed or under light throttle.

   1 related service bulletin

   What to check: On a test drive, note any idle surge at stops, hesitation off idle, or a wrench/failsafe message; have a shop pull stored codes related to the throttle body. Ask whether the throttle body was cleaned or replaced and whether the idle-surge service bulletin work was done.

   2 excerpts from owner complaints in NHTSA records

   “I was driving in my 2005 Ford 500 with 84,000 miles on it, down a busy highway in the left lane on sept. 30, 2012, and all of a sudden my car would no longer accelerate. The speed continued to decrease and I had a car directly behind me and a car directly to the right of me, so I could not immediately pull over to the shoulder of the highway. …”

   NHTSA complaint #10478532, filed 2012-10, 84,000 miles

   “I am yet again having throttle body problems with my vehicle. In december 2012, Ford issues a statement to customers tellin us to go have the throttle body cleaned, but that did not fix the problem. It put a temporary bandaide on the real problem that Ford does not want to take ownership for. Even after I had my vehicle serviced and reprogrammed, it still idles high and jerks. …”

   Transmission and drivetrain

   Harsh or delayed shifting, sudden neutral, loss of drive

   • 18 complaints (18%)
   • median 136,500 mi at 9.9 yrs old (16 state mileage)
   • filed 2013–2017

   Owners describe hard or delayed shifts, lurching when moving between drive and reverse, and the transmission dropping out of gear or into neutral while cruising. Some report the car refusing to shift out of first or second, revving high, or losing power at 35-40 mph with the wrench or transmission light on. In several complaints a dealer's diagnosis was that the transmission needed replacement, and some vehicles were not repaired. Mostly reported from about 65,000 miles upward, with many at 100,000 to 200,000; often at highway cruise or when accelerating to pass.

   What to check: Drive the car through full stops, low-speed creep, and a highway merge, and feel for clunks, flares, or delayed engagement; check the transmission fluid level and condition and ask for any service records, including PCM/TCM reprogramming.

   “Vehicle downshifts very hard when braking or when trying to pass someone and you give it gas and it downshifts to accelerate it's like the vehicle goes into neutral. I was doing 70mph with someone on my rear end on I-77n and when I tried to speed up to get out of his way car shifted really hard to where I thought something broke and started to slow down quickly. Since I had the cruise control on the car shot up to 7000 RPM. …”

   NHTSA complaint #11043409, filed 2017-11, 125,507 miles

   “The car has lost the ability to accelerate on the freeway while I was driving it. Had to limp off to the side to try to reset vehicle. After getting to the shoulder of the freeway, I could only drive the car no faster to 35 MPH because there was no throttle response and it would not shift out of first gear. This problem also effects shifting into reverse. When it is occurring you will notice a hard shift into reverse that tears up the gears. This seems to happen every couple months with no notice.”

   Body and structure

   Door latches and handles stick or fail, worse in cold

   • 9 complaints (9%)
   • median 95,000 mi at 9.4 yrs old (7 state mileage, few)
   • filed 2013–2017

   Owners report that in cold weather the door latches freeze, doors will not open or will not stay shut after opening, and interior handles fail to latch. Some say a latch or handle was replaced or sprayed with lubricant and the problem returned, and a few report that prior latch recall work was done but the problem persisted. Reported mostly between about 50,000 and 150,000 miles, and repeatedly tied to freezing or near-freezing temperatures.

   What to check: Open and close every door several times, check that each latches firmly and the interior handles return, and ask whether latch recall or repair work was completed on the car.

   “Past recall on door latches. Work was done by previous owner. Problem still persists - have to drive car holding door shut with hand. Ford said nothing more they can or will do. Local Ford dealership wont do anything either. Problem has been going on for the past 3 winters when it gets really cold.”

   NHTSA complaint #10819876, filed 2016-01, 112,000 miles

   “Vehicle door handles freeze in temperatures below approximately 25 degrees fahrenheit. At which point after you open the door it will no longer close. If you slam the door hard enough it will close but potentially will cause damage to striker in door.”

   Electrical system

   Instrument cluster and gauges go dead

   • 10 complaints (10%)
   • median 117,500 mi at 9.5 yrs old (8 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2014–2018

   Complaints describe the instrument panel going dark intermittently, with speedometer, tachometer and fuel gauge stopping, warning lights all lighting at once, and reverse or brake lights behaving oddly. Some note the cluster resets by itself while driving, and others say a dealer diagnosed the cluster as needing replacement. One owner also reports the fuel gauge reading incorrectly, leading to running out of fuel. Reported from roughly 50,000 to 150,000 miles; described as intermittent at first and then nearly constant in some cases.

   What to check: Start the car and watch the gauges sweep and settle, check that all warning lights behave normally, and ask whether the cluster has ever been replaced or repaired.

   “Ford told me in 2012-2013 there was a recall on the instrument cluster, the previous car owner had brought to dealership and fix. Well the same issue is occurring now ( 138kmiles) I started the car 4/1 and the reverse lights stay on, dash board gauges are off ( no speed, RPM, fuel gauge working) the vents wont work. I continued to drive car for about 1-2 miles ( at felt like 35-45mph) and as I am driving the computer reset ( car did not turn off, this is still when the car is in motion) and all the gauges started to work. …”

   NHTSA complaint #11082480, filed 2018-04, 138,450 miles

   “Instrument cluster stops working at random, no fuel, speed or RPM information. All the warnings lights come on and brake lights illuminate even when brake pedal is not used. This problem has gone from intermittent to almost always happening. Most recently the car has lost the ability to accelerate on the freeway while I was driving it. Had to limp off to the side to try to reset vehicle. …”

Buying note. These cars are old enough that condition and records outweigh the badge: a thorough test drive that exercises the throttle, transmission and gauges, plus a pre-purchase inspection that reads stored codes and checks for rust underneath, will tell you more than the mileage. Ask specifically about throttle-body service, transmission repairs and prior latch or cluster work.
