Has anyone notice lane centering not centered?

[inmanlanier]

We're on our third trip of 725 miles both ways, and I have again noticed a bias in the car's centering behavior when on cruise control with the lane centering feature enabled. I noticed it during the first two trips - then the windshield got replaced which prompts a recalibration of the system. On this first leg out of state this 3rd trip - the same occurred. Today I tried a test (1 data point - need to validate with more) - I gently drove over to the right white line, and I noted that right when my mind concluded the tires were at or near the line the steering wheel chattered and the car torqued steering to the left. When slowly going toward the two center lines, however I noted that until I thought I was definitely further over to the left (i.e. onto the left most line) than the prior test, then the steering wheel chattered. On the interstate coming up, I noted that a couple of times it drifted gently to the left part of the lane on gentle right turns to where the tires were riding on the lane dividing reflectors before the system started to act.

So... I believe mine has a bias too far to the left.

Has anyone noticed a bias in your 'centering'? If so, what have you done about it? Does anyone know of or heard of a way to 'calibrate' the device or bias it either way?

I can't imagine trying to explain this to a service advisor so it can be accurately communicated to a tech. They'll likely hook up a test device and say 'it all checks out OK!'

Yes, mine does the same...just too lazy to do anything about it...

Mine is very close to dead center with maybe a very minor left bias. I have driven quite a few vehicles with lane centering and my Aviator is the best so far. I leave it on all the time. There is a VERY complex alignment process with special equipment to calibrate the feature. I am sure I posted this topic before, but please see:

as one of many examples.

The shop that replaced my windshield is who does my dealer's replacements. They used an OEM windshield and obviously have the equipment.

Do you know if there is a way to 'adjust' or alter the bias?

The only thing I have seen done is the complete calibration. There may be a simpler way to adjust the bias but I am not knowledgeable enough to make that call. You might want to ask a technician who performs the calibration if there is a subset of the adjustments that might work for your specific issue.

 

[inmanlanier]

I'll call the shop that did my replacement and ask.

Me and my husband say the say thing. The lane center on cruise only. The regular lane assist is fine. But on cruise it can be jerky and not centered at all. I know your hands should stay on the wheel but I have tested this with hands just off the wheel and the lane centering is not to be trusted in my mind. i notice this only on cruise.

I don't use the centering or keeping feature as I don't have faith in either. Using the lane keeping is liable to end up with me getting pulled over for DUI.

A lot depends on the type of road markings, light conditions, shadows . . . . . Mine works nicely but road marking standards will have to be put in place for current ADAS technology to be more reliable. That said, I am happy with mine and use it 100% of the time..

The outfit that replaced the windshield said they don't calibrate. This will likely be fun when we get back home (sarcasm).

Surprising! It seems like they should have told you that before they replaced the windshield so you could have taken it somewhere else. I would request a refund.

I distinctly recall a discussion where that was part of the service. Like everything in today's world, I should have gotten it in writing, witnessed, notarized and video recorded. They were, of course in denial as to my recollection.

In Florida for 'comprehensive' claims we the insured pay nothing. If the standard process is for the windshield to be replaced first and then calibrated later, so be it. The calibration part will be done by Lincoln and if there're a charge outside warranty my comprehensive insurance will pay it.

I'm just concerned that before I replaced the windshield there was a bias. After they replaced the windshield there is a bias. I'm assuming there's some 20 year-old tech at the dealership that really doesn't have much understanding of what is being done to calibrate - he'll simply 'plug and play' and my outcome may the the same.

My challenge will be to very clearly and very objectively explain to them the car behavior that is not correct so that at least I recorded it. When complete with their work, if needed, I go back with the same objective documentation. Unfortunately I've been there before, and with the discounted labor rates Ford/Lincoln reimburses the dealerships for warranty coverage, usually it's not the smartest tacks in the tool tray that get the assignments.

It is a shame you have to go through that. I just had my oil changed. I went to top off my washer fluid and found that they threw in a freebee.

Luckily it wasn't a large tool!

Interesting they didn't at least attempt to schedule for a Ford/Lincoln shop to calibrate. They had to know that changing the windshield would mess up the calibration. Even the smallest degree off makes a difference.

If it were me, I wouldn't even mess with the glass replacement shop unless you just want to gripe. I'd call the insurance company and express my displeasure. Then I would take my vehicle to Ford/Lincoln dealer for calibration. This too should be covered by insurance.

 

[inmanlanier]

Perhaps you missed my syatement this is who Lincoln told me to go to!

 

[inmanlanier]

And yes, Lincoln will do the cal.

I did miss that statement. Sorry about that. This is interesting. Obviously a disconnect somewhere. Wonder if you are the only one who didn't get a calibration at this place? Or better yet, the only one who has noticed the difference from a calibrated vehicle, to one which isn't!

 

[inmanlanier]

The other thing FYI that was interesting is that before going to them there was some bias (i.e. as it came from the factory). I was going to deal with it later, then the windshield event happened.

We're headed home next Friday. I'll do some tests and see if I can record video as well (likely hard to discern, may not help).

The shop told me they do not have the calibration equipment, they only replace glass and and would have made that clear to me. I had a different recollection, but in the end hopefully it will not matter. I'm over 60, but don't think my memory has declined that much for stuff like this!

I didn't think we had lane centering - just lane keep assist. Two different features if I'm not mistaken. Are both offered as separate options?

They are separate. There is a Lane Departure Warning which is separate from keeping the vehicle centered in its lane. I am not sure if either is optional.
