Drive Control Malfunction after car wash

[Bandroid]

I have a 2019 Platinum. I took the car for a pressure wash today (twice in the past), just after it was done I notice several error messages.
-Drive Control Malfunction Service requiered
-Hill descent control fault
-Hill start assist not available
-Pre-collision assist not available
-Service advance track
-Park Aid Fault
-Lane keep assist not available

Someone can tell me what happened?
The car is still under warranty

Did you spray under the hood? If so, I suspect you got the battery and/or fuse panel wet. That many errors likely means it's an issue with the battery and or battery connections. Check your connections and the state of charge of the battery and put a trickle charger on if needed.

No under the hood. Undercarriage. I read somewhere that could be fuse 15 or 16 or something like that going bad. I will check it anyway

Hope you get it figured out without too much hassle. If not an obvious battery or fuse related issue, may be worth a trip to the dealer since it's under warranty.

If I were you, and I can't believe I'm saying this, but I wouldn't tell the dealer you had just washed it. Others have said on here you shouldn't pressure wash these for various reasons. But you might be giving them something to argue about, when in reality that should hold no water and wouldn't if you faught it.

I have never in my life been told not to pressure was a car, now of course, I've been told not to pressure wash an engine bay directly, but I have with every previous car as long as I protected certain things from direct spray. It's a freaking $70k+ car, that is supposed to be in inclement weather and be okay. No matter how much cardboard you put under a vehicle, or how much rubber you put in the wheel wells, water is going to get in the engine compartment, and it should be okay.

maybe it is a dead battery, and it's an easy fix. Hope for the best for you.

It's absurd that these vehicles have such touchy electronics. My 1st gen is misfiring again. We had just a little bit of rain and it was parked for days. .

Yeah, don't volunteer that you washed the undercarriage. It failed in warranty that's it. Next they will say you must avoid puddles.

I had this happen when I was driving in a huge snow storm just before Christmas. About 100 miles into the trip. 4A snow mode 40 MPH tops, all those warnings came up and it went into limp mode. Luckily I was 10-15 miles away from my gas stop. Pulled over and got gas, cleaned all the cameras and sensors off, looked under the hood and car. I couldn’t see anything out of the ordinary. Started it back up and all wrench light was gone and I had full power with all the drive modes restored. Drove out of the storm and it hasn’t done it since. All the codes showed up on the Ford Pass app. I was going to have them check it out at the dealership next oil change. Totally suck if it’s moisture related.

I will take it to the dealer on Friday. I will let you know what they say.

I had mine throw a fit like that once when I started it up at the grocery store. Shut it off and started it up again and all the various errors were gone. Ford app captured all the errors as well.

guess they all have one “freak out” session?

Its most likely a wiring connection at the front strut.

If that happened to me it would be the last straw.
Sorry to say it, but if snow makes my car go into limp home mode, it would be limp to any other dealership to get rid of it.
IDK about you, but I get the feeling Ford has been relaxing a bit in their standards of QC...

Rant off----

get used to it, with all the complicated electronic BS on todays vehicles, reliability is going to tank....

All the modern cars are going to have moments where they need a reset. Just be glad they aren’t running Microsoft software

Yep it was a inside joke

I partially agree with this statement. Think how many electrical issues mercedes had for years as they pushed the envelope with many technologies, but there are actually very few things this vehicle does that my Jeep didn't do. It had adaptive cruise, adaptive air suspension, auto wipers, you name it. Was the hemi as complicated as this DI turbo v6, no, but with mds, 16 spark plugs, etc, it too was pretty techy.

But if you skimp on connectors on struts that don't properly seal and prevent water intrusion, that's a self inflicted QC issue. I literally drove through a river in my wk2 with water starting to trickle into the cabin through the door seals and never had an issue because of it (luckily my breather tubes were all extended with traps to prevent issues) but still, I think we're all seeing that the more advanced things get, the more likely they are to fail, but poor quality on top of that almost guarantees failure. Like these rear defraot connections, wtf? Shocks/struts failing at 20k... Nuts to me.

Sorry, rant. Wish I didn't love driving this so much, and wish I wouldn't lose so much cash now if I got rid of it. if driving through snow, or going through a car wash is going to cause this many things to fail, then there definitely is a quality control/engineering issue.

Its a Auto industry issue with parts venders switching quality/ materials mid supply run. Its impacting every brand. You’ll get 5000 good connectors and wiring harnesses then the vender cheaps out on wire or connectors and bingo you get a batch of cars with serious failures or worse. If anything the Auto makers all know that incoming parts need constant quality checking or it costs them big later with repair costs even lawsuits etc.

Toyota still has some "old school" SUVs I have had my eye-on to include their venerable V-6s/V-8s. Something with a real shifter and real parking brake, and not 2 turbos, 2 fuel systems, etc. The only tech I get excited about is for the safety stuff, and that is pretty low-tech IMHO. I know people who will change cars to match their phone software.
YMMV

So when I do jump, I probably won't have to get "used to it" but I will see an increase in reliability vs and extra 3-6 highway mpg. I currently have a half page of minor things to be fixed by dealer on my 2020 Ex, ranging from cosmetic, to electronic, to mechanical. I am not even including the startup wastegate-lobster boat sound effects.

In fact, in almost 35 years of new, old, and used vehicles this has been the least reliable in 10 months of ownership. To include boats.

I'm in the same boat. I bought this thing because of what i thought I was getting out of the engine/fuel economy (well and despite others, I actually like the ride and styling as well). This was my first Ford, given my experience with the vehicle and ford customer care, not sure it will happen again. I also really wanted to support an American brand. Sad part is, I researched the heck out of these, and it really seemed like reviews on Ford in general between 2016 and 2018 were doing so much better.

P.S. I Love your description of the wastegate sounds. Neither me or my dealer have heard back from Ford, even after escalating 3 times on this issue.
