1623 miles on the car, a little over a month in, and I'm driving down the street at 30mph when there's a loud alert sound and the dash info screen flashes a warning, "Automatic transmission failure. Do not shift out of D or turn off the car." After a few seconds, it goes back to showing the normal info screen with the Automatic Transmission Failure warning symbol at the bottom. The funny part is, nothing changed about how the car actually drove: I could still slow to a stop (though I turned off the auto-stop), accelerate from standstill, pass, etc. without any bad behavior. Anyway, at 5:15 p.m. on a Saturday the service departments were all closed but fortunately my dealer's sales floor was still open, and I was able to drive straight there, leave the car in their lot and pick up a Stelvio loaner.

First question: anyone seen this? My guess is that it's just a computer glitch, but obviously I wouldn't want to risk it on a brand new car. Hopefully I'll find out on Monday.

Second question: again, I'm 1600 miles in. What the actual heck?

That is disappointing for sure. Too many similar stories being told here. Mine broke down at 1063 miles. Good luck with your issue. Hopefully your dealer is equipped to handle this.

Be sure to get a Giulia as a loaner.

Was your issue fixed?

@Astigmatism,
Please post reasons and results of this experience.
Also, please post year and model of your Giulia.
It is easy to create a "signature" with this information that will appear with all of your posts.:smile2:
Thanks,

@AlfaAndy, not sure what you mean by "reasons" beyond what I've posted; results will have to wait. My car is a 2018 Giulia Q4 Ti Lusso with the Ti Performance Package.

Just got a call from the dealer: according to them, the problem was the battery, which wasn't putting out the proper voltage and therefore was somehow to blame for the warning light. I have no idea whether this is true or not - on the one hand, it seems based on reading the forums that lots of people have had battery issues, but on the other, it also seems based on reading the forums that lots of people's problems haven't been solved based on an initial, simple battery-based diagnosis.

I'm planning to pick the car up tonight and keep my fingers crossed going forward.

I am not going to say I am any type of expert on this or say that what the dealer states is correct or not, however, based on my electronic background/degree and experience and all the varying issues that have been posted on this forum the battery is the week link and it is very possible the cause of a lot of issues with the car for a lot of people. Improper voltage and or unstable voltage will cause all sorts of issues. Loose connects and bad grounding can also cause the same issues and the combination of all is a nightmare to trouble shoot.

The battery is everything on the car and all modern calls for that matter. Gone are the days we could put a battery in a car, start it, pull the battery and drive around all day without an issue. I just had to replace a failing battery in my 2002 Silverado. It was slow to crank over due to the week battery and for what ever reason, probably due to the voltage level the Tow/Haul feature would turn it's self on once you got it started. A very odd thing to activate due to a low/failing battery.

Modern cars have lots of computer processors that require a minimum voltage to operate. Most processors require 3.3 volts and can only allow for +/- of about 5%.

@Woodstk88, I'll cross my fingers that this was it. I picked the car back up this evening and drove it home with no issues; according to the work order (the service department was closed by the time I got to the dealer), the battery failed the "GR8 test," they were advised by Alfa Romeo to replace the battery, they did so, and now it "holds a charge normally and there are no warning lights on." If that's the only problem and it works going forward, I'll consider myself extremely lucky.

Do these cars have AGM batteries? Is everyone disabling their engine auto stop/start?
Apparently it is valve regulated flooded cell, made by Varta (Germany?).

Lead acid batteries can be damaged by improper charging, out of range temperature and shock. Shock includes persistent vibration, dropping the battery and hitting and/or torquing the battery leads.

Freezing temp for a lead acid battery is about -40F when fully charged, but only +20F when the battery is discharged. Freeze damage is extremely destructive and cannot be fixed

The electronics in the car should not use battery voltage directly. Instead there should be voltage conversion HW known as a voltage regulator. A well designed voltage regulator should be able to cope with a wide range of conditions. However, the power amp inside the infotainment system may require proper battery voltage to work.

@Astigmatism,
Thanks for reporting on the diagnosis and repair.
I hope that the new battery is the proper fix!

Hi Astigmatism,
This is not what we hope to hear from our customers. It is important to us that you are enjoying our time as a Giulia owner. We would like to make sure we offer our assistance while you are working with your dealer. Please send us private message with additional information so that we can look into this further.

Had the exact same thing as the original post happen to me this morning. I dropped it off at the nearest dealer this morning. I really hope it's just a battery/glitch issue and not something serious. :(
