The dealer (Cincinnati Columbia Accura) has confirmed the fuel pump safety recall but has done nothing to fix it.

This car has repeatedly had issues with delaying to take off when I touch the gas pedal. Once the pedal is depressed there is a long delay before the car actually moves. Two days ago as I was driving at around 35mph all warning lights came on and the car started jerking as it was trying to slow down or stall. I was able to get back to my home luckily I was only up the street and was able to drive under 30mph and had to pull off the road several times because it kept jerking almost as if someone was repeatedly slamming on the brakes. I had a mechanic hook a reader up and was able to determine it was the high pressure fuel pump. Acura claims my car has no open recalls but I believe although it may not be currently it obviously should be part of the recall involving the same exact issue. The warranty expired 3k miles ago ironically, but given this issue has happened to other cars of the same make and model and given the recall for this same part on other cars like mine just with a different vin I believe it should be covered as it is a major safety concern. The car jerked very hard and luckily I did not have my kids with me and luckily no one was too close to me when my car starting stopping in such an forceful way. If I was on a Highway I would have probably been involved in an accident as the car was attempting to go into limp mode due to the failure of the fuel pump and was aggressively shifting down when I was only going 35mph I can only imagine what could happened if i was traveling double that speed.
