Just got the car back from the dealer today. The windows were not working because there was a cut wire and so it blew the fuse. So he fixed the wire and replaced the fuse. As for the sluggish acceleration, I get the standard "no issues found" response. On my way out of the dealer it did it again but there is no consistency with the sluggish acceleration. I will keep driving it until I figure it out. At least I have my baby back!!!
