I have an 06 gtp, and have some slipping like a shutter, upon left turns mostly but some when I turn right. I originally thought it was the transmission. Had it pressure tested and it has no codes in the history. So I started looking at drive axle shaft slipping due to gear shearing in the transaxle. Nothing found. I noticed an electrical plug on the rack... electronic power steering! Check the fuse box and the 80 amp eps fuse is not there at all. What am I missingdash and I have ever yet to locate a steering assist box anywhere on the steering shaft.
