Sean121580 Report post Posted August 17, 2021 (edited) Hi all, I was wondering if anyone has ran into the issue of the 2017 Ford Fusion Hybrid displaying multiple issues on start up. and power steering stops working. 1. steering assis fault service required 2. lane keeping sys malfunction service required 3. adaptive cruise control not available 4. hill start assist not available 5. pre-collision assist not available Once we start driving the car for 2 minutes, everything clears and power steering returns and all is well. this is reproducible every time we turn the car off and back on. The only thing I have tried so far is taking battery post off for 10 minutes and putting back. TIA, Sean IMG_8008.mov Edited August 17, 2021 by Sean121580 Quote Share this post Link to post Share on other sites
ElectricFan69 Report post Posted August 22, 2021 The root cause could be one of any number of things - ranging from something as silly as a loose connector, to damaged wire, to sensor or rack failure. The diagnostic steps in the service manual would be a good place to start - although that will reference the factory scan tool that is too pricey for most DIY folks. With the current crop of computer-networks-on-wheels, a scan tool is a first step to having the car 'tell you where it hurts.' A visit to the dealer or a qualified specialty repair shop would be in order if you haven't the scan tool resources. Quote Share this post Link to post Share on other sites
