2022 XLT AWD Ecoboost low speed braking issue

[zachj95]

Hi all,

Really been scratching my head trying to fix this issue. I have a 2022 Ecoboost AWD at 37k miles.

When I'm braking at low speeds the front end will sort of buckle like it's downshifting and the revs are going too low. This is really annoying in stop and go traffic.

If I put the car into neutral and brake it doesn't have an issue, which leads me to believe it's an issue with the drivetrain (maybe transmission/cv axle?).

I took it into a shop and they did a brake inspection and found no issue with the brakes/suspension.

Has anyone run into this issue? I suspect it's my transmission, but at 37k miles I feel like this shouldn't be happening.

I'm trying to make sense of your description. What do you mean by "buckle"? If the transmission is downshifting, that would make the RPMs go higher, not lower.

Sorry, the brakes will basically progressively grab harder until it downshifts, then it does it again until it comes to a complete stop.

Let's say my foot is on the brakes at 50% pressure, the actual brakes will feel like they'll go from 30% -> 70% -> 30% -> 70% on each downshift.

Thanks, I think I understand your meaning now.

My Maverick downshifts more aggressively than other automatic transmission vehicles I've owned in the past, and I've found I have to modulate the brakes more due to this as I'm coming to a stop than I did with those vehicles. It took me a while to get used to this when I first bought my Maverick, but I became accustomed to it and now it's second nature. As it downshifts approaching a stop, it slows more than I expect it to for the amount of brake I'm applying, so I have to modulate, or ease up a bit, on the brakes to make a smooth stop.

Does this sound like what you're having to do?

You mention that you have a 2022 at 37K though, is this characteristic something new that you've just now noticed? Did you buy your truck new?

Yeah I've had the truck for 10k miles now and the issue hasn't started to pop up until recently.

OK, that's too bad. I was hoping that it wasn't a new issue, or that you were new to the truck and I was onto something.

Sounds like a software issue, Try different driving modes and see what you get.

What driving mode are you using?
Normal, eco, sport? I don't use sport but I know it changes shifting patterns.

I use them all but notice almost similar to you in sport. That's why I suggest trying different ones to see if it changes it. In which case it would almost be certain a software issue.

 

[zachj95]

Changing driving modes didn't seem to affect anything. I also noticed my CV boots were leaking at only 37k miles

My issues don't seem to be directly related to the CV axles, but who knows.

Took it into the shop as it's still under the 5-year 60k powertrain warranty. The service guy also told me that the front half shafts are under a 10-year 150k warranty.

Yep the 22-24 models got the balsa wood half shafts- My first one went at like 20k- and now on a 2nd full replacement set done about 2.5k miles ago with the upgraded units- My whole truck started to wobble at highway speeds- Nice and quiet now- The axels originally were only covered for the 5/Year- 60k power train but they bumped that up knowing how bad the first versions were.

I was going to suggest bringing it in and have the dealer document your concern.

If the transmission fails next year soon after warranty - you still may have a case for a warranty claim.

Yes a hassle. BTW, my EB in Sport Mode will downshift and accelerate a bit. Used to it now.

I would make sure they replace them using the standard powertrain warranty. The extended warranty language reads as a "one-time repair if needed to the front half shafts for 10 years of service or 150,000 miles..." So my interpretation of that is if they use that 25N09 Program for this repair, it's used up and no longer available since it is a one-time repair. It does not provide coverage for unlimited half shaft repairs for 10/150,000. So by using your standard powertrain warranty for this repair, then you will still have the 10/150,000 for a future half shaft repair within 10 years, 150,000 miles. I'm no lawyer, but that's how I understand the 25N09 extended warranty. I would suggest verifying that with your dealer. If they say differently, I would have them confirm that with ford and get it in writing. Just my 2 cents.

99 percent sure that's how this is being played out- Just got my 2nd set of the now upgraded units at 36K-

Yep, if you got covered with the 25N09 extended warranty as I did, keep that in reserve until the standard powertrain warranty runs out. Thankfully, so far at 38K I haven't had any issues.
