Hello everyone. My first post here. I recently bought a 2011 V6 Limited with 84k miles that has a few problems I was hoping to be able to fix. One of them is that since I bought it I noticed the steering wheel was not returning to center at lower speeds and at higher speeds in the highway I would have to keep correcting the steering. It feels like the steering wheel STICKS and refuse to come back to center. I have done a lot of research, tried an aftermarket Intermediate steering shaft, taken the car to a Toyota Dealership where they changed the Intermediate steering shaft and the rack and pinion but the symptoms persist. Now they told me they are thinking it might be "some kind of electrical motor". Has anyone ever experienced this or can guide me towards the possible culprit. I can provide as many details as you want. Sorry for the lengthy post but now I am desperate. I have not been able to enjoy this wonderful car and I am concerned with its safety now. Please, any help is HIGHLY appreciated.
