What owners report

Complaints on this model year center on the manual and automatic transmissions, especially the six-speed manual used with the V6 and 5.0L engines, where owners describe hard shifts, gear lockout and grinding. A second cluster involves the automatic transmission downshifting or losing power on its own, sometimes with the speedometer dropping out. Air bag inflator recalls and electronic throttle body symptoms also come up repeatedly in the sample.

  1. Transmission and drivetrain

    Manual transmission hard shifts, gear lockout and grinding

    • 152 complaints (32%)
    • median 6,000 mi at 0.7 yrs old (137 state mileage)
    • 9 mention a crash, fire or injury
    • filed 2011–2025

    Owners of cars with the six-speed manual report that shifts, particularly 1st to 2nd and 4th to 5th, take heavy effort, grind, or refuse to engage until the lever is released and retried. Some describe the clutch pedal sticking near the floor at high rpm, drivetrain whine under throttle, or a vibration and shaking while coasting or accelerating. Complaints say dealers often replaced the fluid or could not duplicate the problem, and several report parts back orders during repairs. Reported from very low mileage (under 5,000 miles on several cars) through the 40,000-90,000 mile range.

    3 related service bulletins

    What to check: Drive the car through all gears cold and warm, including a high-rpm 1st-to-2nd shift, and listen for whine or grinding. Ask whether the transmission fluid has been changed and whether any transmission work or rebuild has been done.

    2 excerpts from owner complaints in NHTSA records

    “I was completing a left turn when power was no long going to the back wheels while releasing the clutch. It happened again when I arrived home while pulling in to the driveway but this time I smelled the clutch overheating. I lost confidence that the vehicle will provide the necessary acceleration that is need while crossing traffic at an intersection.”

    NHTSA complaint #10471959, filed 2012-08, 10,428 miles

    “Same as everyone I know high rev lockout, can't shift past 7krpms clutch pedal sticks to the floor. Gears are rough to get into normal. Will hear loud clunking when changing gears sometimes. Car has 35k miles I bought it with 17k miles and the issue has always been there. This needs to be addressed this could cause transmission failure and accidents if it fails on highways.”

  2. Transmission and drivetrain

    Automatic transmission downshifts or loses power while

    • 174 complaints (37%)
    • median 6,012 mi at 0.8 yrs old (157 state mileage)
    • 12 mention a crash, fire or injury
    • filed 2011–2025

    Complaints describe the automatic-equipped car suddenly dropping into a low gear at highway speed, the engine revving, the speedometer reading zero or failing, and warning lights such as the wrench icon coming on. Some owners report the car jerking or stalling and later restarting normally, and several say a dealer diagnosed the molded leadframe or transmission range sensor. Others report no drive or reverse engagement after starting. Mostly reported between roughly 40,000 and 130,000 miles, often at highway speeds.

    Recall 16V248000Recall 12V1900003 related service bulletins

    What to check: Ask whether the molded leadframe extended-coverage program was applied and whether the transmission range sensor has been replaced. Check that the speedometer and warning lights behave normally during a highway test drive.

    2 excerpts from owner complaints in NHTSA records

    “My Mustang has been doing this more frequently now, where I'm driving highway speeds and the transmission suddenly downshift to low gear from high gear. This afternoon it almost caused me to crash on my way home from work on the freeway. This is completely unacceptable and life threatening. I went on google, to look up if others are having this same issues and I came across a lot of mustangs of this year have the same exact issue. Matter of fact, Ford is aware of this issue but why hasn't a recall been put out to fix this transmission problem. …”

    NHTSA complaint #11210234, filed 2019-05, 103,000 miles

    “While driving the car shifts down into first gear on its own while the dash goes blank and the speedometer stops working. It will also show a wrench light at times.”

    NHTSA complaint #11355418, filed 2020-09, 87,000 miles
  3. Vehicle speed control

    Stalling or no acceleration from electronic throttle body

    • 81 complaints (17%)
    • median 50,000 mi at 4.0 yrs old (75 state mileage)
    • 2 mention a crash, fire or injury
    • owner-quoted repair $713 (median of 8 quotes)
    • filed 2011–2025

    Complaints describe the engine cutting out or the car refusing to accelerate while driving, with the check engine and wrench lights appearing, then normal operation after a restart. Several owners say a dealer or independent shop diagnosed the electronic throttle body, and some note the repair was not covered under powertrain warranty. A few also describe unintended acceleration or a sudden loss of power during a turn. Spread from single-digit mileage up to about 87,000 miles, with several reports in the 12,000-68,000 mile range.

    2 related service bulletins

    What to check: Ask whether the throttle body has been replaced and whether any related codes are stored. On a test drive, watch for hesitation, a wrench light, or a drop in power.

    2 excerpts from owner complaints in NHTSA records

    “My car would die while driving. It was very dangerous in heavy traffic and would have to turn the car off and back on just to crawl into a parking lot, so I had it towed and the computerized engine diagnostics at the napa auto care center showed a malfunction of the throttle body.this repair cost me $726.32”

    NHTSA complaint #10786942, filed 2015-10, 2 miles

    “On february 16, 2013 on a clear sunny day, without warning (no check engine light or other visible/audible signal), my Mustang began to sputter and die while driving at 65 MPH on a local freeway in the fast lane. Efforts to downshift and rev the engine to keep it alive failed. I was forced to pull the vehicle hard over to the breakdown area in the center of the highway just as the engine completely died. Efforts to restart it failed - the engine cranked, but would not turn over. …”

Example complaints

Transmission and drivetrain: “Fyi I can not include the top/roof due to it wont allow me to input the check mark) I baught this Mustang in june 2012,used from Ford here in sioux falls sd, since that time I have asked about the top about the clunking and if they would notify me if any recalls. They only sent one for the passenger air bag , until this week when I received a second notice for the takata air bags from the day I took her off the lot. …”

NHTSA complaint #11221204, filed 2019-06, 35,000 miles

Air bags: “Takata my car has different manufacturing issues including the convertible roofing it does openly by itself, I got scared and chocked the first time it happened, also the transmission seemed to sent a lower speed to the motor. Airbag didn't explode in a crash. Driving is when it happens.”

NHTSA complaint #10949175, filed 2017-02, 49,000 miles

Vehicle speed control: “Lost power in my 2012 v6 Mustang. Wrench light came on indicating limp home mode. Was able to pull off to the side of road. Turned engine off and the it was fine for about two miles then cut off again. Restarted again and was able to make it home but the engine light is on. Going to try and get it to the shop tomorrow, but this is a severe safety problem in my mind. Was lucky I didn't get rear ended”

NHTSA complaint #11082382, filed 2018-04, 80,000 miles

Engine: “Air bag recall and iam having a code for electronic throttle body control issues that should be a recall from what I heard but my local Ford dealer said it wasnt.”
