I just got a 2016 F150 Platinum, it has less then 400 miles on it now. I noticed a slight pull to the left, took it to the dealer and they said they made a slight adjustment. The truck still pulls to the left and I'm tempted to go back to the dealership. Checked the tire pressure and all 4 are showing 39psi. Anyone else have this issue?

 

cross the ft tires (discount tire will do it for free) and see what happens

 

I didn't know if I was crazy or just overly sensitive, but I swear I've felt mine was a little off. I noticed the other day I was having to keep the wheel slightly to the right to keep it straight on the road. Had my truck 4 weeks now with about 1500 miles, not sure if the dealer will do anything for me. And sometimes it seems fine so I dont know if its just in my head or what

 

If you do a search, you may find others that have had the same issue. I seem to remember reading several complaints others had. Dealers switched tires, aligned, changed steering components, etc., etc, on some, others their dealers said it was normal. Seems some trucks are affected more than others, or some just notice the issue more. Seems like it's just in the EPAS and how the software is configured.

Good luck, hope the tire swap helps.

 

Has the song irreplaceable by beyonce played in your truck? It may have something to do with it

 

My 2015 was pulling to the left, worse at highway speeds (400 or so miles). Took it back to the dealer and they aligned it. Toe was out. No more problems

 

EPAS PDC Overview Ford Motor Company January 2016
Version 1.0 1
Understanding EPAS Pull Drift Compensation (PDC)
NORMAL OPERATION
EPAS equipped vehicles have a Pull Drift Compensation (PDC) feature to assist drivers in compensating for
variations in road and driving conditions, such as a crown in the road. PDC is automatically enabled at vehicle
speeds above 40 km/h (25 mph) when yaw sensors indicate the vehicle is traveling straight. The system will not
compensate if driver input torque, steering wheel angle or vehicle yaw rate is too large. The feature works by
adjusting power assist offset which reduces the steering effort (input torque) required to keep the vehicle
traveling straight. PDC ramps in steering assist offset gradually over approximately 45 seconds of time, to
neutralize or reduce steering efforts. The feature updates automatically and continuously, but not instantly. PDC
only works with hands on the steering wheel and does not steer for you. Some situations may feel different than
driving a vehicle without PDC. Just after moving to the opposite side of a crowned road, drivers may feel the
input torque required to compensate for the crown increase, but this will fade out in approximately 10 seconds.
Turning or taking a gradual curve in the road can reset PDC, resulting in steering effort returning to pre-PDC
levels until continued straight driving above 40 km/h (25 mph) resumes. These conditions are all normal system
operation refer to the Workshop Manual (WSM)
for diagnosis.

Purchased a 2018 5L uses with 28k miles.
Noticed this tendency to favor the left.
I decided to take a different approach.
Noticed an improvement in steering with a load of passengers and a load in the box.
Decided dealer would not be any improvement.
Used a local alignment shop with the latest rack and explained what I see in steering and asked for more caster to be adjusted into the front .
Put on rack printed a readout before making any changes.
Found the right rear a small bit out!. Indicating the Axle tube may have been out of alignment when assembled in their fixture.
Not to correct this but go ahead with adding front caster.
Print out after changes to show where and how much of change, and still be within specs.
Result was a elimination left tendency pull and better feel in steering and tracking.
Long straight flat roads will track a long distance before steering correction need to be done.
I am satisfied with the out come. Now the same as any other vehicle I have owned.
Opinion only: Ford needs to review their correction algorithm.
I think all that was accomplished with different alignment was counter it. So it may be fine with different alignment.
