What stands out
Cruise control accounts for 41% of every owner complaint on file for this vehicle — the dominant problem area across 5 categories tracked.
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.
The failure pattern owners describe
Owners describe the vehicle accelerating on its own to speeds of 50–85 mph without touching the gas pedal, with engine RPMs climbing to 3,000–4,000+ even in neutral or park. The event is intermittent but often recurs within hours or days. Braking slows the car but doesn't fully stop acceleration; drivers report feeling the engine pushing against the brakes, causing jolting and shuddering. Tapping the gas pedal, shifting into neutral, or shutting the engine off temporarily halts the problem, though it typically returns.
Cruise control failure commonly precedes or accompanies these events. One owner noted cruise control stopped working 30 days before unintended acceleration began. In some cases, toggling cruise control on and off temporarily alleviates high idle, but the function is then lost entirely.
The vehicle also idles at 2,000–3,000+ RPM at stops, requiring brake pressure to prevent forward lunging. One owner reported an accident at 5 mph when the accelerator stuck, resulting in totaling the vehicle.
Dealership repairs have included throttle body replacement ($376), cruise control cable replacement, gasket replacement, and accelerator cable lubrication. However, owners report the problem recurring after each repair, including cases where both cable and throttle body were replaced. No lasting fix has been confirmed across these narratives.
Failure modes owners describe
Unintended acceleration / throttle sticking
Engine revs and vehicle accelerates without driver pressing gas pedal. Occurs at various speeds (5–80 mph). Engine RPMs climb to 3,000–4,000+ in drive, neutral, or park. Braking does not reliably stop the vehicle; driver feels acceleration pushing against brakes. Issue intermittent or persistent. Tapping gas pedal, shifting to neutral, or turning engine off temporarily stops event; problem often recurs.
When: Occurs across vehicle lifespan; reported at mileages from 19,500 to 150,000+. No clear timing pattern.
Symptoms owners cite: Vehicle accelerates without foot on gas pedal; Engine revs to 3,000–4,000+ RPM in drive or neutral; Brakes struggle to overcome acceleration; Vehicle lurches forward or jumps to 50–85 mph; Problem intermittent or repeats within hours/days; Tapping gas pedal temporarily fixes issue; Engine continues revving even when in park
Repairs/costs cited: Dealership replacements cited: throttle body ($376 reported), cruise control cable, gasket. Independent mechanic throttle cleaning noted. Lubrication of accelerator cable and throttle body performed without lasting fix in one case. One owner reported both cable and throttle body replacement needed for safe operation.
Recalls/TSBs owners mention: NHTSA investigation ongoing; no recall issued despite investigation. Owner (#4) notes dealer replicated problem and replaced throttle body. One owner (#6) mentions Ford dealership identified broken cruise control cable as culprit and advised checking cables.
Cruise control malfunction / disabling
Cruise control fails to engage or maintain set speed, then ceases functioning entirely. In several cases, cruise control failure precedes or occurs alongside unintended acceleration events. Turning cruise control on/off sometimes temporarily resolves high idle, but permanent loss of cruise control function results.
When: Reported ~30 days before related acceleration issues in one narrative; occurs at various mileages.
Symptoms owners cite: Cruise control will not engage or maintain preset speed; Cruise control stops working completely; Clicking sound heard when toggling cruise control; Cruise control appears to engage but acceleration uncontrolled
Repairs/costs cited: One owner (#11) powered down engine after hearing click; cruise control did not work afterward. No repair documented in most narratives.
High idle on startup and at stops
Engine idles at 2,000–3,000+ RPM when vehicle is stopped at traffic lights or in park, instead of normal ~600–800 RPM. Brake pressure required to keep vehicle stationary.
When: Occurs from low mileage and across vehicle lifespan.
Symptoms owners cite: Engine idles at 2,000–3,000+ RPM in park; High RPM at traffic stops forces driver to use brakes to stay stopped; Vehicle lunges forward when brakes are released
Accelerator pedal vibration
Pedal vibrates during acceleration; vibration increases with speed. Dealer repositioned cable underneath pedal without resolving issue.
When: Reported from 19,564 mileage onwards; occurred every drive since vehicle purchase.
Symptoms owners cite: Accelerator pedal vibrates during acceleration; Vibration intensity increases with vehicle speed
Repairs/costs cited: Dealer repositioned cable beneath pedal; problem persisted.

My car has accelerated without application of the throttle. I did not have cruise control on or engaged and the car continued to function as if the gas pedal was depressed. This has happened on several occasions now. Once, while at a speed of about 30 MPH, I was able to safely pull over and put the car in neutral. The engine rpms continued to race upward as if the car was under load and under…
Tl* the contact owns a 2005 mercury sable. The contact stated that while driving 30 MPH, the vehicle suddenly accelerated to 60 MPH. The contact took the vehicle to an independent mechanic however, the vehicle was neither diagnosed or repaired. The manufacturer was contacted. The failure mileage was 80,000.
While driving I experience acceleration of vehicle. I pulled over on a side street and into a parking lot put it in neutral. It continued to rev high and subsequently I turned the vehicle off. When I turned back on it continued to rev and I turned it off. On second attempt of turning vehicle on it began to idle correctly. Has recurred 5 times since first malfunction on oct. 31st. *tr
Tl* the contact owns a 2005 mercury sable. The contact stated that while driving 55 MPH, the vehicle accelerated independently to 80 MPH, without warning. The contact mentioned that the brake pedal was depressed to slow the vehicle down. In addition, the vehicle then failed to accelerate. The vehicle was towed to the contact's residence. The contact contacted an independent mechanic and informed…
Tl* the contact owns a 2005 mercury sable. The contact stated that while at a stop sign the vehicle erroneously accelerated. The contact shifted into the neutral in order to stop the vehicle. The contact was able to shift back into drive where the vehicle resumed normal function. The vehicle was not taken to a mechanic. The vehicle was not repaired. The manufacturer was not contacted. The failure…
Driving the vehicle at about 30 MPH. The car accelerated to about 60 MPH at which time I was riding the brakes the entire time till I could pull over. The engine goes to 4000 RPM while in park. If restarted its the same thing. This was happening off and on. I took to garage and they cleaned and checked carburetor and fuel pump. It continued again and I finally took it in again. This time…
Car suddenly accelerated. I traveling under 30 MPH car began accelerating on it's own! I braked and RPM's continued rev-ving at 3000. Put car in neutral- did not stop rev ving. Placed in park- same thing. Turned it off- same thing when the light turned green I put the car in drive and it peeled away. At that time I tapped the gas and the problem corrected itself. This was the third…
Can not see out my front and back windows. I will clean the windows 3-4 times a day. Improper codes requesting repair and once repaired still the same thing. Starts no cranks. Very dangerous conditions, could not continue to work due to vision issues. Anti theft functions preventing me from operating my car.
My car is accelerating on its own like the gas pedal is stuck or something. The RPM goes all the way up to 4,000. It is very scary because you don't have control of the car speeding on its own which is very hard to come to a complete stop .when I finally manage to stop the car by putting the car in neutral and hitting my breaks, I then put the car in park. The car still continues to accelerates…
