Throttle body is giving me trouble. When I am at a light or stopped my car accelerates by itself. Is a safety issue as sometimes I am at a pedestrian crosswalk or just at a light. Very concerned about this issue. *kb

What stands out
Owners have filed 150 engine 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 engine complaint has been filed on this vehicle in over 14 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2005 Ford Freestyle has a well-documented throttle body defect that causes unintended surging and power loss, particularly in hot weather with AC running; the part fails repeatedly even after replacement, and Ford has never issued a full recall despite years of complaints. If you are considering a used Freestyle, get a pre-purchase inspection focusing on throttle response and demand a warranty covering throttle body repairs for at least 12 months.
The 2005 Ford Freestyle engine develops a throttle body problem that causes dangerous surging and loss of power. Owners report the vehicle lunges forward or backward at stops, during gear shifts, and in parking lots—even when the brake is pressed hard. Most incidents happen in hot weather with the air conditioner running. The surge often peaks at 2000+ RPM, making the brake alone insufficient to hold the car in place.
The problem starts mildly but worsens over time. One owner had surging occur 6–7 times per 25 miles. Power loss is worse: the engine suddenly quits responding to the pedal, the wrench light comes on, and "Engine Failsafe Mode" appears on the dash. The vehicle limps along at 20–30 mph until restarted. Owners on forums (myfordfreestyle.com) identified the throttle body as the culprit years ago, yet Ford did not issue a recall.
Replacement costs $520–$900 depending on the shop. Parts were on national back order for months in 2009–2011, leaving owners without transportation. Even worse, the replacement throttle body fails again after a few years, forcing owners to pay the full bill a second time. Ford issued a Technical Service Bulletin in December 2005 acknowledging the problem but offered only a "customer satisfaction" cleaning, which does not fix the defect. One owner's sister received a recall for the identical issue in a Lincoln LS, while the Freestyle owner was denied coverage.

Failure modes owners describe
Electronic Throttle Body Malfunction - Surging & Lurching
The throttle body fails to control idle correctly, causing the engine to rev uncontrollably when shifting into gear or coming to a stop. Owners report sudden surges of 1–5 feet or more, even with the brake pedal firmly applied, particularly in hot weather with AC running. The surge happens at low speeds, during parking, reversing, or at traffic lights. In many cases, brake pressure alone cannot prevent vehicle movement. The problem occurs intermittently but with increasing frequency, and often worsens over time.
When: Variable; symptoms reported as early as 2008 and ongoing through 2016. Most incidents occur in hot weather (80–100°F) with air conditioning on. Surging typically happens during low-speed maneuvering (parking, reversing, drive-thru lines, school pickup zones), but also reported while stopped at red lights or in traffic.
Symptoms owners cite: Engine revs to 2000+ RPM without driver input; Vehicle lurches or surges forward or backward at stops or during gear shifts; Brake pedal pressure insufficient to prevent movement during surges; Increased severity in hot weather when AC is on; RPM overshooting corrects itself with hard brake application or stalling; Surging typically occurs when AC and power steering draw max power from idling engine; Frequency increases over time from occasional to multiple times per trip
Codes mentioned: P061B, P2106, U0141, Check Engine / Wrench Light activation, Engine Failsafe Mode message on dash
Repairs/costs cited: Throttle body replacement costs owners $520–$900 depending on labor and dealer. Owners report parts frequently on back order (months, even until Nov 2009 in some cases). Ford dealers initially unwilling to perform repair under warranty once out of coverage. Some owners attempted cleaning throttle body themselves with temporary results. Newer design throttle bodies installed by Ford post-repair reportedly have corrected gas re-routing design (per dealership service rep in narrative #3).
Recalls/TSBs owners mention: Ford issued Technical Service Bulletin in Dec 2005 for this exact issue. Owner forums (myfordfreestyle.com) and internet searches reveal TSBs referencing the problem. Ford offered a 'customer satisfaction recall' involving cleaning and resetting the computer, but owners report this does not fix the underlying defect. A related investigation PE11-018 was opened May 11, 2011, for surging. Lincoln LS (sister vehicle) was recalled for throttle body linkage replacement; identical symptoms in Freestyle were not recalled. Several owners report Ford representatives acknowledging the design flaw but denying recall coverage.
Loss of Engine Power & Failsafe Mode
The vehicle suddenly loses engine power while driving, forcing the car into failsafe mode with reduced performance (max ~20–30 mph). The wrench light and 'Engine Failsafe Mode' message appear on the dash. Power loss occurs both on the highway (dangerous) and at low speeds. Restarting the vehicle temporarily restores function, but the problem recurs. Owners describe it as the engine not responding to the accelerator pedal.
When: Reported from 2010 onwards, occurring sporadically at first but increasing in frequency. One owner reports 6–7 incidents per 25 miles. Events happen both in city traffic and on highways.
Symptoms owners cite: Complete loss of engine response to accelerator pedal; Wrench light comes on; 'Engine Failsafe Mode' message on dash; Engine dies or enters limp mode limiting speed to 20–30 mph; Vehicle becomes immobilized or severely undriveable; After restart, vehicle temporarily returns to normal; Problem recurs within days or weeks
Codes mentioned: Wrench light / Engine warning codes, Engine Failsafe Mode flag, P061B (reported in some cases)
Repairs/costs cited: Diagnosed as throttle body malfunction. Throttle body replacement corrects the issue. One owner reported four codes pointing to electronic throttle body. Dealer diagnostics confirmed throttle stuck open in at least one case; cleaning provided temporary relief but problem returned.
Recalls/TSBs owners mention: Investigation PE11-018 opened May 2011 for sudden power loss and failsafe mode events. Ford TSBs issued but no full recall implemented as of complaint dates. Owners report dealers telling them the part was on national back order for extended periods.
Throttle Hesitation & Stalling on Acceleration
The vehicle hesitates when the driver presses the accelerator, then either lurches suddenly or fails to accelerate smoothly. Engine stalls intermittently, particularly after initial hesitation. A strange noise is reported. Wrench light comes on. The car exhibits delayed response and poor acceleration quality.
When: Reported starting as early as 2010 and continuing through subsequent years. One owner first noticed hesitation in early 2010 at 61,540 miles.
Symptoms owners cite: Hesitation when accelerating from stop; Strange noise heard during acceleration problems; Stalling after hesitation; Delayed engine response to pedal input; Wrench light activation; Poor acceleration performance; engine revs but car does not move forward quickly
Codes mentioned: Wrench light / Check Engine codes, U0141
Repairs/costs cited: Throttle body replacement resolves hesitation. One owner had throttle body replaced twice—first at cost of $638.97 at 61,540 miles, then again under warranty at 65,207 miles when problem recurred within months. Owners report recurring failures requiring repeated replacements.
Recalls/TSBs owners mention: Throttle body failures covered under warranty initially, but owners report the defective part fails again after warranty expires. One owner notes being told 'the part is not covered under extended powertrain warranty' after first replacement.
Engine Control Module / Electrical Corrosion Issue
One owner with documented service history reported that lurching and unintended acceleration stopped permanently after a non-Ford mechanic cleaned and sealed the ECM (Engine Control Module) pins with corrosion inhibitor and terminal sealer. The mechanic diagnosed ECM moisture/corrosion as the root cause. The problem recurred 4 years later, suggesting the issue may be environmental moisture ingress to the ECM.
When: First episode occurred after rain, 2008. Recurred 4 years later in 2012, again after wet weather conditions.
Symptoms owners cite: Lurching forward or backward involuntarily; Tendency to happen after rainfall or wet conditions; Problem stops when ECM pins cleaned and sealed; Recurrence suggests ongoing moisture/corrosion vulnerability
Repairs/costs cited: Non-Ford mechanic cleaned and tightened ECM pins, sealed with terminal sealer/corrosion inhibitor. Cost not specified. Resolved problem for 4 years before recurrence.
Throttle Body Part Shortage & Supply Chain Failure
Owners consistently report that Ford dealerships could not locate throttle body replacement parts, with parts on national back order for months (some until November 2009). One certified mechanic owner reported the dealer had the car for 2 months searching for a replacement throttle body, eventually discovering Ford Motor Company itself had zero stock and had to locate a vendor capable of manufacturing the part (die-cast with machining and sensor/vacuum integration). Vehicles sat in service departments for extended periods, leaving owners without transportation.
When: 2009–2011 timeframe reported most frequently for part shortage issues.
Symptoms owners cite: Throttle body replacement delayed indefinitely; Vehicles unable to be repaired for weeks or months; Owners told to drive unsafe vehicles while waiting for parts; Dealers gave loaner cars only for short-term warranty repairs, not extended back-orders
Repairs/costs cited: Throttle body is a die-cast part requiring machining, sensor fitting, wire port fabrication, and vacuum socket integration. One owner reported dealer told him Ford was searching for vendors to manufacture the part due to production plant shutdowns. Owners without extended warranty faced significant financial and logistical hardship.
Recalls/TSBs owners mention: Ford Motor Company acknowledged zero inventory and inability to expedite parts manufacturing. Dealership told one owner with terminal illness (requiring wheelchair-accessible vehicle) that they had exhausted all options to locate the part and could only wait for manufacturing. No loaner or compensation offered for extended outages.

Purchased used Ford freestyle december 2010. Ran fine until warm weather and use of air conditioner. With a/c on, the electronic throttle control seems to often greatly overshoot the correct setting when shifting from neutral to drive or reverse, which causes a significant engine RPM increase and a momentary "lunge" if the brake is not applied very firmly. Many vehicles do this to a minor…
2005 Ford freestyle-the ac compressor and drier was replaced at about 93,000 miles through the extended warranty. It only cost me 75.00 . No big deal right. The total bill was nearly 1600.00 for the warranty company. Now at 125,000 miles, it has gone out again. No warranty. I've to pay. It is going to cost about 1600.00. Now they can't find a compressor and are back ordered until april of…
