First Dealer Warranty Visit -- Issues & Outcomes

[MidLifeManifustang]

For those who are experiencing some of the same annoyances with their S650 as I have, here's the list of issues I took to my dealership today and the outcomes:

• Audio via CarPlay is intermittently silent (detailed post: CarPlay audio intermittently silent)
  • May be fixed soon - quoting my repair order: "FORD IS AWARE OF THIS CONCERN AND ARE DEVELOPING SOFTWARE TO CORRECT PLEASE CHECK AT YOUR NEXT SERVICE". The dealership told me it can affect Android as well as iOS devices, and may be an OTA fix.
• Back window on passenger side must be raised and manually tilted forward before front window or it doesn’t seal properly (detailed post: Back window not always sealing right)
  • Fixed: The RO just said "ALIGN BOTH RIGHT SIDE GLASS" and mentioned removal of the passenger door trim, which suggests they may have adjusted the track on the door window as well as tweaking the rear window glass
  • I'm going to try lubricating the track to prevent recurrence, as other users have suggested.
• Locking and unlocking by touching the door handle is intermittent / often unreliable (detailed post in this thread: Delay lock touch button)
  • Not fixed - probable design flaw. The service advisor let me speak directly to the shop foreman / tech and he said the antennas on the Mustang aren't as large as those on my '21 Explorer (my point of comparison for proper operation) and the behaviour is typical and he can't do anything about it.
• Lane centering assist feature is unusable because it keeps warning to keep hands on wheel while hands are on wheel (detailed post: S650 Mustang -Keep hands on steering wheel message)
  • Not fixed - probable design flaw. The tech told me the system relies on rotational input (not pressure or weight on the wheel) to assess whether or not you're holding the steering wheel. I asked it if was possible to change the sensitivity on it, i.e. require less rotation, or require it less often and this is not possible at the dealer level.
  • So if you're using this feature on a straight and flat road that requires no steering input, the system will keep warning you to keep your hands on the wheel unless you're providing artificial steering input just to let it know you're there.
• At highway passing speeds and full throttle, the engine hits rev limiter before the automatic transmission shifts and the engine cuts out for a second (detailed post: Rev limiter or fuel cutoff before A10 shifts)
  • Not fixed - Since the issues is happening only at pretty high speed, they obviously didn't attempt to replicate the issue. At first the tech was telling me I had hit the governor limit (no, I said, my speedo is indicating well short of 250km/h [155 mph] and it keeps accelerating hard after the delayed shift) and then he suggested it was the timing being retarded for a fraction of a second to soften the shift (no, power is being cut off entirely for a full second). He finally seemed to get there was a problem but shrugged and said it's unlikely we'll be able to do anything about it because:
    • Dealers don't have access to tweak the shift points
    • Resetting the transmission would just make the car drive weird for a while and probably not fix the problem
    • If I provide a data log so they can see the issue happening, the best he could do would be to send it to Ford but then Ford would be unlikely to fix it because, he said, changes to the tune require government emissions re-certification, which costs "millions".
  • It seems my best hope on this one is for someone to unlock tuning capability at some point.

Hope this is helpful.

... Back window on passenger side must be raised and manually tilted forward before front window or it doesn’t seal properly (detailed post: Back window not always sealing right)...

this has been an issue with convertible Mustangs since at least 2015. these quarter windows move in a complicated motion, and i honestly cant see ford making an effort to fix this since the issue is going on at least year 10 now

...Lane centering assist feature is unusable because it keeps warning to keep hands on wheel while hands are on wheel (detailed post: S650 Mustang -Keep hands on steering wheel message)...

this is fully intentional, and its for safety reasons, the same reason why BlueCruise is only usable on select vehicles and select highways. ACC with lane centering is similar but not the same as BlueCruise, and frankly, using like it is BlueCruise is exactly why ford added that message

...At highway passing speeds and full throttle, the engine hits rev limiter before the automatic transmission shifts and the engine cuts out for a second (detailed post: Rev limiter or fuel cutoff before A10 shifts)...

this is likely because the transmission learns and adapts to your driving, and even learns differently in different modes. from my experience (i've had this happen to me), it usually happens when you use M mode and dont shift before redline a few times. the transmission seems to learn during M mode usage. what might fix it is resetting the adaptive learning and getting better at timing the paddle upshifts since there is a delay

the other two issues with the lock on the door handle and Android Auto/Apple Carplay randomly going silent are things i've noticed too. the door handle thing is probably not going to be fixed, and ford at this time have made no mention about an update, OTA or otherwise, fixing the intermittent Android Auto/Apple Carplay silence issue

 

[samson]

Your dealer is right about the carplay issues also present in android auto. Mine does that occasionally. Also yesterday my GoogleMaps went blank on the center screen even though AA was connected and otherwise functioning fine.

I also get the "hands on wheel" warning on my car even when my hands are clearly on the wheel. And manual GTs don't even have lane centering. I get the message I guess from the lane keeping system.

Same deal here with the door lock working intermittently on the driver side. Works perfectly on the passenger side but the driver side works for me only maybe 60% of the time on the first tap of the handle. I've started just using the fob.

Total bullshit. Mine works perfectly fine and always has.

Hate to break it to you, but lane centering assist is not "hands-free". Your car does NOT have hands-free driving. BlueCruise is hands-free, and is only available on certain vehilces.

Your car is doing EXACTLY what it's supposed to do. I cannot believe the dealership or tech didn't tell you this.

I confirm both of these issues on my ’24 MDH.

Your hands being "on" the wheel isn't enough. There is no sensor in the steering wheel. It needs rotational input.

The second one is NOT an "issue". You don't have BlueCruise. See my response above to @samson

Right, but I don't think Ford intended to repeatedly warn drivers whose hands are on the wheel and paying attention to keep their hands on the wheel and pay attention. The way the system determines that my hands are on the wheel is what I consider to be a design flaw, not the warning itself.

this is likely because the transmission learns and adapts to your driving, and even learns differently in different modes. from my experience (i've had this happen to me), it usually happens when you use M mode and dont shift before redline a few times. the transmission seems to learn during M mode usage. what might fix it is resetting the adaptive learning and getting better at timing the paddle upshifts since there is a delay

The tech didn't think a reset would make a difference when I suggested it. I don't use the manual paddles that often and didn't establish any sort of over-revving pattern before I observed this. It would be nice it if could sort itself out by learning over time that I don't enjoy hitting the rev limiter when I actually want it to shift to the next gear.

If you're expecting there to be some magic sensors in the steering wheel to know if you are touching it or not, that isn't the way it works.

A self-healing vehicle. Invent that and you're a zillionaire

One more tidbit about the CarPlay thing I forgot to mention. The dealership included a reference to SSM 52574 on my repair order, which provides more detail about the issue.

The Sync/CarPlay/AA has (for many years) and will continue to be a clusterfook.

in fairness, there are at least a couple companies that have made capacitive sensors for the steering wheel, being IEE and Joyson Safety, but most manufacturers use a system to detect slight movement and resistance

While there may very well be some, I'm not personally aware of a single mass-produced vehicle that comes from the factory with capacitive sensors in the steering wheel to detect if you are touching it or not.

 

[samson]

Your hands being "on" the wheel isn't enough. There is no sensor in the steering wheel. It needs rotational input.

This happens when actively driving with both hands on the steering wheel. You should not have to jerk the car back and forth for the system to recognize you are on the steering wheel. My wife's Acura has the same system and has never given a false "hands on wheel" warning in the 5+ years we've had the car. That tells me either Ford's system is inadequate or a tweek needs to be made to the sensor that picks up the rotationof the wheel.

It doesn't know you're touching it just because your finger is touching it.
