Vehicle Veers violently to the left. HELP!

[nklomsue]

Hopefully someone can give me some input what this issue can be. I have been having this issue for about 4mos now. The vehicle veers to the left during a quick acceleration out of a turn and more noticeable during normal driving where upon letting of the acceleration during 2nd gear the vehicle will quickly sway to the left. I have had a wheel alignment, struts and shocks checked, wheels speed sensors checked, wheels balanced and tires inflated to proper psi. Odd thing is it only happened when the vehicle is in second and I letbof the gas pedal. The veering is quite strong and very noticeable. Any input would be greatly appreciated and TIA.

First off, if it's under warranty, take it to the dealer. 4 months is a long time to put up with the driveability problem you are experiencing.
Secondly, who checked out your Sport?
Did they acknowledge or witness the problems you discribe?
I can understand the vehicle veering during hard acceleration (torque steer) combined with a subpar road surface the Sport will wander and dart.
For deceleration if you are mechanically inclined I would start with jacking up the front left to get the Wheel off the ground and check/feel for excessive drag (resistance) while moving the wheel, high resistance can mean the brake caliper is not fully releasing or possibly a wheel bearing issue which could be causing the pproblem. Obviously It's very difficult to diagnose a problem on an internet forum, hopefully the problem gets resolved soon.

These might be your other posts same topic ?

I think you have a 2022 Big Bend?

Did you buy the vehicle new?

Any chance a lift has been installed or do you know that?

When did the issue first occur?

How many miles on the vehicle now?

Have the drive axles checked and any bushing attached

Yes, it was new but had a lift kit installed. Had the lift about two years now and the problem just occurred. Thought it was alignment but have that done. Small note sometimes the traction control light comes on and the vehicles brakes engage.

Oh it has 41k miles

Unless you are good with maintenance on that lift and with front end repairs it seems like you’ll want to find a good mechanic you trust

Or are you pretty capable with all that?

Looks like a lift issue

Since you had the struts, alignment and tire pressure checked another possibility is that the Sport has ESP, the electric power steering and traction control work together, You noticed warning lights associated with those systems. You can turn off the traction control and lane centering to see if that's causing the problem. I have read about the lane centering system overreacting, and steering the vehicle where you don't want to go.
You would have to go to a decent shop or Ford dealer to check for codes or system errors.

That's not a small note; that's something that needs to be addressed immediately. If the brakes engage uncommanded you do not have full control of your vehicle.

Doesn’t the EPAS and ABS systems use vehicle dynamics (pitch, yaw , roll, CG, weight, tire size, etc.) and if you install an aftermarket lift kit and larger tires, it will affect the stability and handling of the vehicle?

An by doing so, you violate the warranty, adversely affect the safety of the vehicle and its occupants, and loss of insurance claims if the alterations were found to be a contributor in an accident?

Probably all true but you see lots of lift kits added and not much reporting if a lift kit was found to be the issue in an accident or with warranty .. at least I haven’t read stories on that but also haven’t looked for them

pitch, yaw, roll, CG, mass… sounds like you’re referring to satellites … just add inertia to the mix ?

Back to the lift kits, owners with lift kits do love them … life is all about compromises
