Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2006 Ford Fusion owners, lightly cleaned up (personal details are redacted by NHTSA).
Airbags did not deploy during car accident. Airbags recalled by Takata are far more dangerous, basically dead airbags. The vehicle was in motion, another recall with the carpets being recalled as well, resulting in excessive speed from the carpet pressing on the gas peddle, causing the accident.
2006 Ford Fusion: when driving after the car gets warm up it is starts slipping and shifting someone harshly like it just got kicked. I was on the freeway and couldn't speed up almost got rear ended. I see others have the same issue after doing a search I found different answer as what could be wrong. Found out what the issue is with the aisin transmissions slipping which were used in the 2006 Fusion. It is due to valve bore wear in the main control. If the trans fluid isnt burnt (meaning there is internal trans clutch damage) then you are looking at $800-$1000 to replace the main control. If the clutches are burnt the whole trans will have to be replaced cost??? Something like $4000-$5000. The problem is that when Ford bought the aisin trans, Ford did not buy the service rights. So there are no service parts available or training avail on how to service this trans. …
I started having issues with my car in 2008. My car then would not go any faster than 50 MPH would not accelerate on the freeway on ramp , and could not go up hills. So I repaired it or so I though. Now bring me to last year 2014 I still experience all that pull when traveling but now my speedometer was going crazy and would just go up to 100 MPH as I was sitting at a stop light/sign. Fast forward to August 2014 when I had the speed sensor changed...and now I'm in March 2015 and again my car pulls, me speedometer goes crazy. Well as I was driving with my two children in the car ages 5 years, and 7 month old. I was rear ended while pulling up to a stop sign!!! Luckily it was just enough to scare my daughter and I was just a bit sore the whole day but things could have been worse! After reading up on the sure my issue I am having I just about had enough! …
After slowing down just before the stop sign, my car started to sputter and when I tries to accelerate after the intersection it stops accelerating. I had to limp along to get home. Luckily, I was just about 1.5 miles from home. I have done for this car all scheduled maintenance and never missed the recommended periodical oil changes. I drive less than 5000 miles a year with this car an it has less 59,000 miles on it. This must be due to a defective part from the factory and I should not pay for it. I have left it parked on my driveway until I hear from you and by way of your good offices hopefully from Ford. Thank you for kind assistance. [redacted]

Fusion has issues accelerating while in motion. The issue has happened on the highway and city streets. When the gas pedal is pushed, the car will not accelerate and the RPM will jump. This causes safety concerns because while driving, car will suddenly not accelerate in traffic and I have to pull to the side of the road while the traffic around is going at a higher speed and has potential to cause an accident. The car appears to have trouble switching between gears and car jerks in the shift.
Thermostat sticks open (cold) while driving. Sudden jumps to normal temperature range followed by drop to cold again. Vehicle has hard time starting when temperature gauge is on cold mark after running for any period of time. Thermostat has been replaced with no improvement. Throttle sticks on acceleration causing engine to bog down and almost choke out followed by sudden burst of acceleration that could lead to accident.
-steering-the steering wheel shakes eveytime I slow down the vehicle. -speed control-the vehicle skids/swerves as I'm driving. -brakes-the brakes are faulty as well. -electrical system- the charging system needs to be checked. (shown on indicator) -**vehicle is making a loud humming noise when accelerating/driving (front of vehicle) *there is already a recall for the airbags as well. -didnt pass safety inspection
My car slips out fo gear, slows down on the highway, revvs at high RPM's, and won't accelerate again unless I slam the gas pedal down. It only does this sometimes. Also, I have been experiencing intermittent brake failure. I apply my foot onto the break, and it goes straight to the floor. Delays stop time substantially.
