Was accelerating in my vehicle when the car hesitated and then just shut off in the middle of the road showing only an orange wrench light on the dash. Thankfully I was driving in town and actually to the dealership to get my airbag recall fixed when this happened and nobody other than my boyfriend was behind me. I turned the key into the off position and turned it back on and the dash (wrench) light indicator went off. I could have seriously injured myself or another vehicle due to what seems to be be a system failure! I refused to take my car home from the dealership until they checked into it. They acted as if it was no big deal because the (wrench) light on the dash went off but I'm very concerned it's a safety issue and bad accidents can be a result of this.

My throttle body is giving me issues. It will hesitate and react as if it will stall on occasion when I am on the highway, it will jerk badly. No engine lights appear on my dash, however I was notified by ford there is a replacement extended warranty, yet that extension does not cover the initial charge from the dealer to check the throttle body out, which is dead wrong of ford. I believe they should cover any and all charges regarding this the throttle body. In addition my vehicles rack and pinion or pwer steering sueels alot while in driving, ive check fluid levels and they are normal, yet it will make alot of noise.

While merging onto a busy highway it became necessary to slow down to approximately 25 MPH and then to speed up to achieve the 55 MPH traveling speed of traffic that I was merging with, the car hesitated for several seconds and then "clunked" into gear and sped up with overdrive engaged. The traffic behind and next to me was continuing at the speeds they were traveling at causing a potential collision. This continues even though I have had my dealer check out the transmission several times. It appears to be a problem when my car has to downshift and then immediately upshift to attain speed quickly as when the car in front of me slows prior to merging with oncoming traffic. I have narrowly avoided a collision three times as a result of this hesitation.

I have had numerous problems with stalling, loss of acceleration, dying with my fusion. It hesitates when driving and stalls when driving and stopped. The wrench and engine light are on again. I am very concerned for my safety due to these issues as there is never any warning of when it's going to occur. I have previously had my throttle body repaired/replaced but the same problems continue.

Car hesitates on acceleration. Happens intermittently but seems to be more prevalent in the morning when first taking off. Even after the car is warmed up and I stop for a light and then try to take off, it will at times hesitate to the point where I feel like I may get rear-ended.
