    It has never been fixed. Car wont accelerate when the weather is hot over 85 degrees . It has done this for last 3 years. Have had in and out of dealer and they can't get it to do the problem!!! this is an ongoing problem for the last 3 years every summer only on hot days. Last week drove about 22 miles nothing happened drove home after shopping for 1 hour left to come home and took over 1 1/2 hours to go 22 miles car wont accelerate. Stop let sit 15 to 20 minutes then can go again for few miles then it does it over and over again.
    Drove today 75 miles one way no problem. Let car cool 30 minutes headed home and went about 30 minutes car would not accelerate again died. Let car set for 30 minutes drove again in stop and go traffic and it went about 2o miles happened again and again at least 6 more times before making it home. Quite tired of this worth less car.

    I had the same issue happen yesterday that others reported. Pulled out of the driveway and car wouldnt accelerate any faster than 10-15mph/felt like it was going to cut off. I had the car towed to a shop and they stated that it was "short in throttle wiring" and therefore repaired the wiring and "cleaned gunk" from the throttle. My check engine light and airbag light had also been on MONTHS prior to the car dying yesterday.

    It seems to be working fine now that they've replaced the wiring, but I'm a little nervous after reading the other comments from owners having the same issues! Hope they've fixed whats truly wrong with it.

    I was coming back to my Mom's when the check engine light came on. Had it checked this morning and they said it was the idle vadidation switch/sensor and so it is costing me 276.47 for the part, 45.00 labor and 90.00 to tell me what was wrong.

    The sluggish acceleration in my Amanti 2006 has occurred since I own the car, which I purchased with 12k miles on it. At times, not predictably, the car fails to accelerate when pressing the gas pedal, then it suddenly takes off with jerk. Cannot reproduce at the dealership and they do not admit of ever hearing of such an issue.

    Slow to accelerate. Happens intermittently, but has done this quite a few times.

    I have not yet taken it into the dealer, because there are other problems with my Amanti. Such as Air Bag light is on (have not been in accident). Whistling noise/sound coming from (sound like) under the engine and louder on the passenger side.

    My car only has 53,700 miles on it and I am the original owner..... not sure what to do because when I take it into the dealer for regular oil changes they can't even fix the dang head lights! I have had it in for the headlights several times.

    When starting up from a light I pressed the pedal and nothing happened. Then, all of a sudden, it peeled out, squeeling the tires. Taking it to the dealer tomorrow.

    The dealer had the mechanic clean the switch contacts and it seems to have fixed the problem, for now.
