2010 Ford Focus Problems

What owners report

Owners of the 2010 Ford Focus most often describe the car briefly losing throttle response or stalling, with the wrench or check engine light, and recovering after a restart; many trace it to the throttle body. Door locks and latches that fail to unlock or open are the second recurring theme. Most reports in the sample fall between roughly 30,000 and 90,000 miles, with a few very early and very high-mileage cases.

1. 1
   Vehicle speed control

   Throttle body failure: loss of acceleration, wrench light

   • 126 complaints (44%)
   • median 51,000 mi at 4.4 yrs old (118 state mileage)
   • 9 mention a crash, fire or injury
   • owner-quoted repair $700 (median of 12 quotes)
   • filed 2010–2024

   Owners describe the vehicle suddenly refusing to accelerate, often at speed or when pulling away, with the wrench icon and sometimes the check engine light coming on; some say the engine revs high or shakes at idle instead. Restarting the car typically restores normal operation, sometimes only briefly before it recurs. Several complaints state a dealer or independent shop diagnosed the throttle body (or its sensor) and replaced it, while others report no stored codes and no diagnosis. Reported from as little as a few hundred miles to over 140,000 miles, with many cases between about 30,000 and 90,000 miles; described as intermittent.

   What to check: Ask whether the throttle body has been replaced and whether any TSB-recommended diagnostics were done; on a test drive, note any hesitation, sudden loss of power, or wrench light and any high or surging idle at a stop.

   2 excerpts from owner complaints in NHTSA records

   “When the car comes to a stop and is idling the engine starts to shake, the wrench light comes on and when I try to accelerate, the car has no power. If I turn off the car and turn it back on, the problem is solved until I come to another stop. The dealership cannot figure out what is happening and they say the diagnostic tool reports no codes.”

   NHTSA complaint #10703213, filed 2015-04, 45,000 miles

   “My yellow wench check engine light came on,I was stopped at a 4 way city intersection and when I stepped on the gas pedal the car would not pick up any speed. I was stuck with traffic behind me. I had to go through the intersection at idle speed pull off the road, turn the car off and wait a few seconds then restart it. …”

   Latches, locks and linkages

   Doors will not unlock or open (lock actuator/latch)

   • 66 complaints (23%)
   • median 54,377 mi at 4.5 yrs old (55 state mileage)
   • filed 2010–2021

   Complaints describe doors that stay locked or cannot be opened from inside or outside, sometimes all but the driver's door, and sometimes intermittently so the fault disappears at the shop. Owners report the key fob and manual key failing to unlock, and passengers unable to exit through a rear door. Several say a dealer replaced the actuator, latch or linkage, and some report the problem returning afterward. Appears across the range from a few hundred miles up to about 100,000 miles, often intermittent and noticed when parking or when passengers try to get out.

   What to check: Before buying, lock and unlock every door repeatedly with the fob, the interior switch and the key, and check that each door opens from both inside and outside handles.

   “I bought this car in 2010. A few months later my children said they couldn't get out of the car even though I had opened my door. I tried to manualy unlock this door and was unable. I made an appointment to get it fixed but on arrival at Ford service it had started working again. When it happened again I made the same appointment this time they saw the problem for themselves. …”

   NHTSA complaint #10513833, filed 2013-05, 1,500 miles

   “I went to use my keyless entry and it wouldn't work I assumed it was the battery so I changed it still doesn't work.so I was having to unlock it by the key.

   Engine

   Engine stalling at stops or while driving

   • 72 complaints (25%)
   • median 47,335 mi at 4.7 yrs old (68 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2010–2021

   Owners report the engine quitting at red lights, stop signs, when slowing for a turn, or while driving, sometimes with a high idle beforehand and sometimes with the check engine light. Restarting usually gets the car going again, but the problem repeats. Complaints mention dealer and independent diagnostics that found no fault codes, and some owners suspect the purge valve or idle control rather than the throttle body. Spread from under 30,000 miles to beyond 150,000 miles, often described as happening at low speed or at a standstill and at random.

   1 related service bulletin

   What to check: Ask about any history of stalling or rough or high idle and whether the purge valve or idle-related parts were replaced; watch the idle quality during a test drive with the engine warm.

   “Would lose RPM's at idle and almost stall. Went to dealership (no help), could find nothing wrong because no codes, even though engine was still idling ruff for them. Dealership was not happy that I brought the car in before 50,000 miles, stating I shouldn't need tune-up til this mileage. Went to a local mechanic (certified) who couldn't find anything, again no codes. The problem continues to date. Going to mechanic for idle sensor replacement, hoping this will help.”

   NHTSA complaint #10543972, filed 2013-09, 49,000 miles

   “Car stalls when no fuel is given, ie: at red light, stop sign, even just slowing down while making a turn. Occurs on city street and highway during stop and go traffic. Brought car into mechanic - did diagnostic, etc. Could find nothing to cause engine to die suddenly. Have happened multiple times. Was instructed to contact Ford dealer.”

   Body and structure

   Premature tire wear and rear alignment noise

   • 50 complaints (17%)
   • median 32,000 mi at 3.1 yrs old (38 state mileage)
   • 6 mention a crash, fire or injury
   • filed 2010–2025

   Owners report tires cupping or wearing out on the inner edge well before expected, along with alignment charges and in some cases a rear adjustment kit being recommended. Several describe a thumping or grinding noise over bumps, wheel bearing replacement, or noise attributed to suspension parts, plus poor handling in wind or wet weather. Complaints note that dealers sometimes attributed the wear to missed rotations and sometimes declined assistance. Mostly reported between about 17,000 and 90,000 miles, often on the second or third set of tires.

   What to check: Inspect all four tires for uneven or inner-edge wear and check tire age; ask whether a rear alignment kit was installed and listen for thumps or grinding over bumps on a test drive.

   “I have owned the car since it was new now has 88k miles I have put literally 4 set of tires on this and have had a rear alignment kit done to it .this car sways really bad at speeds of over 65 MPH and when there is hardly any wind at all . Very dangerous to drive in the snow or rain . The car caused me to have a accident that cost my insurance company over 2000 to repair due to the swaying of speeds over 65 MPH . …”

   NHTSA complaint #10817570, filed 2016-01, 87,500 miles

   “Both tires on back cupped and I was told by dealer that it was because I did not rotate them. I had to buy tires and also pay for alignment. Now at 56251 miles it did it again. Took it to dealer again and now they day it needs a rear adjustment kit that cost $240.00 dollars and I have to pay for it. The service consultant said it was a factory defect but Ford says it isn't and they will not pay for it. Also I took it in because it makes a loud thump when I hit a bump. …”

   Electrical system

   Ignition switch will not crank the engine

   • 24 complaints (8%)
   • median 72,626 mi at 5.5 yrs old (24 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2010–2021

   Owners describe turning the key with accessories working (radio, lights, windows) but nothing happening when trying to start, sometimes with the key not turning fully or the switch feeling bound up. Some report needing to force or wiggle the key or the steering wheel to get it to start. Complaints mention locksmith or dealer involvement, and some describe a related keyless entry problem. Typically reported on higher-mileage cars, from around 50,000 miles up to nearly 200,000 miles.

   1 related service bulletin

   What to check: Try starting the car several times cold and warm, confirm the key turns smoothly to start, and ask whether the ignition switch or lock cylinder has been replaced.

   2 excerpts from owner complaints in NHTSA records

   “The ignition switch doesn't work. You can turn the key on, but it will not make the connection to turn the engine over. We have pushed the key in and turned it on, but still nothing. When the key is in the on position everything works (radio, lights, air, windows, etc.) everything but the engine! When searching this on the internet, I have noticed that a lot of people have had the same problem.”

   NHTSA complaint #11120078, filed 2018-08, 195,000 miles

   “This car was just purchased. Parked car in driveway and the next morning my wife could not start the car. I called seller and he said to 'wiggle steering wheel and car would start.wife could not accomplish this feat. I tried and with much force got the wheel to move and then car started. Problem seems to be in steering wheel. This seems to be a real poor design. I am taking the car to : locksmith and then Ford dealer to see what the fix actually is. Have seen many complaints on this site and others.”

Buying note. A 2010 Focus with a documented throttle body replacement and smoothly working door locks is the more comfortable used-car pick; verify those two items directly, since they account for the most owner complaints. Check tire wear and start-up behavior as well, and ask for service records for any of these repairs.
