AVH failure resulting in locked brakes

Thanks for going into detail about your experience.

You made the right decision to get rid of that car. Your lucky that nothing worse happened

 

Likely electrical failure caused damage to other ecus which took time to fail further.

Too bad.

That car is still being sold on Cars.com right now. Zero of this is on its carfax. How scary is that...

 

So I started my car up this morning and was parked in a lot on a flat surface and the AVH light came on but it was just informing me that AVH was active I thought. Anyway it didn't clear when I drove off and I drove all the way home, about 15 miles and the light was on the whole time but no evidence the brakes were on. I parked it and restarted it and the AVH indicator was gone. Not sure what this was about.

I have never seen the AVH indication before but I always saw it at a particular stoplight with my 991tts. I sit at the same light in the 488 and the indication never shows up. I normally just keep my foot on the brake at that light but with the Porsche, you would see the indication if you released the regular brakes.

 

Thanks for the update.

What do you think of the F8 Tributo? Or is it too much of a reminder of your 488?

 

Thanks for the update.

What do you think of the F8 Tributo? Or is it

I think the cognoscienti agree with you. The F8 will be the last of the old platform, which as you point out, is looking dated in spite
of the attempt to refresh the design.

The two new performance models will be something to anticipate. Hopefully
both new cars will exceed expectations.

 

I’m referring to the new mid rear engine layout models which will replace the 458/488/F8 platform.

One model is supposed to be a smaller displacement V6 turbo. The other has been referred to as “big brother”, a V8 turbo hybrid (I suspect with electric drive to front wheels) which will sit at the top of the sports model line up

 

What debacle? Please elaborate.

I received the AVH and Electrical Failure/Contact Your Dealer codes a few days ago as I started the car to go for a drive. Still in the car, I called my dealer and they asked me to restart. The screens replicated. Tried again, and the error codes did not display. Away, I drove.

One thing that I did that day - and this happened with my 488 at least once before - was push the reverse and auto bridge buttons while the car was early in its diagnostic mode immediately after start. Maybe this is just my experience, but I think that someone else mentioned this before on F chat, and that is that the car sometimes seems to get confused or overloaded when receiving inputs in the startup diagnostic mode. Maybe the Ferrari is just not good at multitasking upon startup.

 

As a 488 owner, I can assure that I have. And while I can certainly empathize with those that have encountered the problem, I do not believe that in a global sense, it rises to the level of it being a "debacle".

 

Correct, no brake lockup. I did not try to drive away while codes were on the screen.

From within my car, I immediately called my dealer service department and they advised on a restart to clear “false codes.” They were adamant that nothing was wrong with the car and intimated that they had seen this many times and that it was battery induced.

While on the phone with them, I searched the code issues and found that what I had just experienced had happened before with others. I mentioned the brake lockup issue you experienced to the dealer and they reassured me that once the codes were gone I wouldn’t have to worry about brake lockup. In the end, they strongly advised that I tend the battery any time the car was not in use.

 

Yep happened to me on the week end.

Got petrol , restarted the car and it was like a Christmas tree. Ever error was scrolling thru. Moved the car a few feet . Turned the engine off then restarted and no errors.

Contacted Ferrari and they said make sure that's its always on tender , which it is. I drive her once a week and even that they said it wasn't enough.

My bad was when it happened I should have looked at the voltage which I didn't.

Im of the opinion that due to the lengthy time it takes for the car to come over that the battery isn't 100% to start with. Im going to monitor the voltage and see what happens

 

Curious do you have electric seats ? Was advised to start car before using any electrical power , eg electric seat memory and windows. Going to check out really how much voltage the alternator gives. Don't know on the Ferrari but standard cars are generally 14.4 volts and then might come down to about 13.5 volts

 

Not any bit less enthused for my incoming 488 but this thread is an eye opener. Sorry to hear OP about your troubles but good for you to stand up for what you think is right and thanks very much for taking the time to share

Might just add my own experience here too. I'm based in Australia and have a 2018 488 spider.

Ive had the AVH failure appear intermittantly throughout the majority of my ownership over the last yeah, and am noticing it even moreso recently. The car is always on a trickle charger when not driven and is usually driven atleast once a week (ive done 11k km in 12 months).

Ive had the Ferrari service guys at 2 different local service centres check it out but so far unable to replicate or find the issue (which is annoying). Last service was last week and it's appeared twice since then. I've started taking photos each time it happens so I can have a running log of how often its occuring, just to help the service guys by giving as much info as possible.

Recently, when I start the car for the first drive its fine, but after I stop at my first destination (recently after about 45mins of driving) and fire it up again, I commonly get the fault. For me I have never had a break lock up yet whilst moving (luckily!). Usually I have to turn the car off, wait some time (usually 5-15 mins), fire it up and hope for the best. Sometimes few starts/stops finally gets it to release.

Quite annoying and is making me drive the car less, especially with others as I dont wanna be stranded somewhere. Im waiting on tyres to come in next week for the dealer, I'm going to bring the issue up again and see what we can do. I'll update here accordingly.

 

Parking brake stuck on, unable to release it to go anywhere. After I cycle the car, sometimes I can get the brake to release and the AVH warning light stays on. Sometimes it just works perfectly after a few attempts (or more commonly after leaving it for 5 mins or so).

Suuuper annoying when you pull into a fuel station, fill up, then get stuck at the pump turning your car on/off for 15 mins lol.
