What stands out
Owners have filed 34 cruise control complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA cruise control complaint has been filed on this vehicle in over 10 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering cruise control on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners describe a recurring electronic throttle body failure that causes sudden loss of engine power without warning. The vehicle either enters limp-home mode (running at idle only) or stalls completely while driving on highways and busy streets. The wrench warning light typically comes on, and the Check Engine light may appear. Restarting the engine temporarily restores normal operation, but the problem returns unpredictably—sometimes within minutes, sometimes after 20+ miles of driving.
Diagnostic code P2111 (Throttle Actuator Control System Stuck Open) is captured when owners use their own code readers, as the fault clears when the vehicle is restarted, making dealer diagnosis difficult. One owner reported the throttle body replacement by a dealer was followed by unintended acceleration; another said a $300 throttle body service left the problem unsolved.
Owners also report unintended acceleration in a handful of cases: one vehicle accelerated at a stop sign without pedal input, another continued accelerating despite brake application. One collision resulted when a stall forced a vehicle into traffic.
The failures occur between 21,000 and 70,000 miles and at any driving speed. Multiple owners note that Ford has issued recalls for the same throttle body defect in other models (Fusion, Escape, Mercury Mariner/Milan) but has excluded the 2011 Mustang from the extended warranty coverage, despite using identical hardware. Repair costs reported: $300–$800 at dealers, with no guarantee the failure will not recur.

Failure modes owners describe
Electronic Throttle Body Stuck Open / Loss of Throttle Response
Engine loses power and enters limp-home mode at unpredictable times, often while driving on highways or in traffic. The throttle does not respond to pedal input. Check Engine or Wrench warning light illuminates. Vehicle can be restarted to restore function temporarily.
When: Between 21,000 and 70,000 miles; can occur within minutes or up to 30 minutes into a drive; frequency varies from once per day to multiple times per trip
Symptoms owners cite: Sudden, complete loss of engine power and acceleration; Vehicle enters limp-home or idle-only mode; Wrench warning light or Check Engine light illuminates; Engine runs rough while in limp mode; No response to accelerator pedal input; Vehicle decelerates and cannot accelerate regardless of pedal pressure; Loss of power can occur at any speed (5–70 mph) without warning
Codes mentioned: P2111 (Throttle Actuator Control System Stuck Open)
Repairs/costs cited: Throttle body replacement typically recommended; one owner reported $800 cost; another reported $300 for throttle body service that did not resolve the issue. One owner paid for throttle body replacement at dealer, and the failure recurred.
Recalls/TSBs owners mention: Ford Customer Satisfaction Program 13N03 extends warranty to 10 years/150,000 miles on throttle body for certain models (Fusion, Escape, Mercury Mariner, Mercury Milan), but owners report Mustang is excluded from this coverage. Some owners mention Ford has issued recalls for the same throttle body in other models.
Unintended Acceleration / Stuck Accelerator
Vehicle accelerates without driver input or refuses to stop accelerating when foot is removed from pedal. Engine continues running at high speed despite brake application. Occurs while stopped or moving, sometimes immediately after throttle body service.
When: Reported at 21,000 miles and other unspecified mileages; can occur while stopped at traffic lights or during freeway acceleration
Symptoms owners cite: Vehicle accelerates without depressing accelerator pedal; Accelerator does not respond to release (pedal stuck condition); Continued acceleration despite brake application; Vehicle lurches forward unexpectedly; Can occur while vehicle is stopped with brake depressed
Repairs/costs cited: One owner reported throttle body replacement by dealer was followed by unintended acceleration; dealer could find nothing wrong on reinspection.
Engine Stall While Driving
Engine shuts off completely while vehicle is in motion at various speeds. Vehicle does not coast; must be restarted. Stalling can occur repeatedly in short driving periods.
When: Between 31,000 and 70,000 miles; can happen once per drive or multiple times within a single trip
Symptoms owners cite: Engine cuts off without warning; No coasting after stall; vehicle stops abruptly; Check Engine light may or may not illuminate; Engine restarts normally after shutdown; Stalling unpredictable in timing and location
Codes mentioned: P2111 (some cases), No code found (other cases)
Repairs/costs cited: Mechanic inspection may not reveal codes on first restart; one owner purchased personal code reader to capture P2111. One incident resulted in rear-end collision with preceding vehicle at low speed (36,264 miles).
Limp-Home Mode Activation with Rough Idle
Vehicle unexpectedly enters limp-home or reduced-power mode, forcing engine to idle roughly. Vehicle loses ability to accelerate and slows dramatically, often while on highways or in traffic requiring evasive maneuvers to reach safety.
When: At various mileages; often triggered by highway driving or while cruise control is engaged
Symptoms owners cite: Engine downshifts to idle and rough running; Dramatic deceleration without driver input; Wrench warning light illuminates; Vehicle becomes nearly immobile in traffic; Evasive driving maneuvers required to reach shoulder
Codes mentioned: P2111 (Throttle Actuator Control System Stuck Open)
Repairs/costs cited: One case reported electronic throttle body assembly (part 9F991) replaced by dealer; comparison drawn to NHTSA Investigation PE13-003.
Transmission Control or Traction Control Issues
Traction control system engages inappropriately during normal driving without hard acceleration.
When: While pulling out in traffic
Symptoms owners cite: Traction control light activates; System engages during light or normal acceleration

Common questions
How serious is the cruise control problem on the 2011 Ford Mustang?
It's a meaningful issue. 34 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $600.
At what mileage does the cruise control typically fail?
Across the 31 complaints that reported odometer mileage, most cruise control failures cluster between 35,000 and 56,200 miles, with the median around 50,000. A quarter of owners report trouble before 35,000; a quarter make it past 56,200. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $600 for cruise control repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to cruise control?
No active recalls currently cover cruise control issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
