We love our new ST but just after 2500 miles we brought it back with transmission issues. Transmission will jolt hard mainly upon deceleration. seems to get worse as it warms up. Our ST is still in the shop (one week now) and we have heard nothing from our dealer yet. I hope this is not a presentation of things to come. Before the issue we thought it was the best vehicle we have had in a long time. Anyone else having issues??
