Steering Assist was once again disabled within a week after the last incident with Steering Assist Caution advisory. This time it almost caused an accident. Steering malfunction happened right at the moment while making a left turn at the inside lane of an intersection. While the steering wheel was turned left to negotiate the turn, the steering became stiff and made the vehicle encroached on the outside lane. Applied brake immediately and forced steered vehicle back to inside lane.

The steering gets stiff after steady driving of 80 to 150 miles. I had it checked at a Ford dealer and was told there was not a recall on this year model for the particular problem. The dealer offered no other explanation or solution to the problem. This happens all the time and only stops after the vehicle rests for several hours. The dates are from Sept. 2018 until now. I bought the vehicle used from enterprise leasing.

After the auto start/stop feature engages the power steering does not immediately return. So when I am stopped at a traffic light, stop sign or left turn and the auto start/stop restarts the engine when I release the brake it can take up to 3 seconds for the power steering to reengage. I have had this to the dealer and was advised that this is functioning as designed. The vehicle did not behave this way when I first purchased. This could be very dangerous in an emergency situation require a rapid restart and turn.

2017 F-150 raptor steering subsystem failure. The steering wheel was forcefully turning itself left and right erratically; up to 90 degree turns very quickly. Very dangerous. I was on high elevation logging roads when this occurred. Overcoming the erratic behavior felt was similar to steering a wheel without power steering. Making turns was near impossible. Failure lights that came up: * low battery features temporarily turned off * steering assist fault service required * terrain management system fault * lane keeping sys. Malfunction service required

Truck wanders all over the road and requires constant correction no matter the road conditions. Once the vehicle speed reaches over 40-45 mph the steering becomes very difficult. Almost as if the power steering assist is not functioning.

When on a complete stop in a traffic intersection, the autostart feature is engaged shutting the engine off. When the left turn light turns green, I take my foot off the brakes and initiate a turn. During this turn, the steering becomes difficult. Here is a link of current complaints: Https://www.F150forum.com/F118/auto-stop-power-steering-problem-399937/

This vehicle has the automatic stop/start feature and for a few seconds after the vehicle starts back up after being stopped- there is no steering control

- Tyler, TX, USA

At highway speeds, on I-15 in Utah at approximately 70 mph, traveling over an overpass bridge to the transition to the highway and hitting the bump the front wheels and related suspension including the steering wheel started to shake violently, ..a condition historically known as "death wobble". this did not cease until reducing speed to below 50 mph. Mileage on the vehicle was 10,141. Vehicle is completely stock with no modifications. After a tire rotation and inspection finding no visable issues the vehicle still continues to unexpectedly/randomly exhibit this problem. This occurs only at higher highway speeds and only after traveling over a transition or rough pavement typically assiciated with an overpass bridge.

The electronic power steering does not work properly when the engine is stopped due to the auto-start-stop feature. I was sitting in an intersection waiting to turn left across traffic with the engine auto-stopped. I released the brake and immediately tried to turn the wheel and the steering would not allow me to move the wheel. It continued to struggle working intermittently for several seconds. This condition is very repeatable. If there is any pre-load on the steering wheel when the auto-start restarts the engine, it takes the steering several seconds to become active. This is a very dangerous situation because I'm giving the truck gas to go into on-coming traffic and the steering is effectively disabled for several seconds. I've reported this problem to my local Ford dealer who said they would escalate the problem. I've had the truck back in for maintenance since that complaint and no corrective measure has been identified or offered. With this defect, I'm left to manually deactivate the auto-start-stop feature every time I'm in a situation where I think I'll need steering input immediately after I release the brake to move forward. I feel like this is a design defect in the truck that creates a potentially dangerous situation where the steering is not available during forward motion of the vehicle.

Ford Motor Company documentation (2017 rv & trailer towing guide) states this model of truck, with the Ford 3.5L ecoboost engine, can safely tow 11,500lbs (maximum loaded trailer weight). Based on personal experience and consulting multiple trailer towing experts, this is a misrepresentation of the material facts and capabilities of this truck. Additionally, it puts unsuspecting drivers in an unsafe and dangerous driving situation.
