SF90 will not start in eDrive

According to my dealer, Ferrari is still sorting out all sorts of little bugs on the SF90, so my guess is that the car has a problem that probably needs a firmware update.

I think I saw it mentioned in a video (I know, not exactly the very best source) the regular manettino has to be in wet mode to engage this mode? Maybe thats worth a try?

 

A software glitch in a new Ferrari?

SHOCKING!

 

That’s it! I’m out! I’m cancelling my SF90 spider order as the “sneak away” option described in the brochure turns out to be all BS! That configuration option is $9875…jeez

 

Some times it does. Don’t know why. Most of times it works.

Iphone disconnects too often. Carplay has so many bugs.

Car is fantastic at least

Dealer called.
Ferrari is checking batteries of SF90s in the service now.
Check up will take 30 mins.
It is good thing that Ferrari is looking into any problems.

same here. This is the best car I've ever had and I had quite a few
@aventadorguy

 

Given that if the car sits for a while(like 4-5days) engine starts no matter which mode, it is the 12v battery that dictates if the engine should be fired up or not at the beginning I assume.

Car needs certain voltage from 12v to start and move properly like any other ICE only car I guess. Since stater generater does not run to keep 12v battery optimally when on ev mode after it is parked long, it needs engine to be run. This is my theory.

That sounds right to me.. however if it’s anything like the Lithium Battery in the Pista, connect the trickle charger everyday, no if’s or buts, even after a spirited drive. Just gone through a nightmare situation.. I would even go as far to say if you can’t connect to a trickle charger every day, wouldn’t buy a Pista…

 

I can confirm 100% that the car i test drove was indeed able to start in E mode

SF90 only starts in electric if the engine is warm. It will never move away in electric if the ICE is cold. Also it has taken a 15 minute drive before the ICE could be turned off.
This is with a US car. Europeans often get better results.

 

I think it is battery temperature that dictates. If it’s too cold the car uses the ICE to heat it.

 

That’s very weird, I can reverse my car and drive away in electric only without even starting the ICE.

 

That is incorrect. I can start in elec even the car is not running for 2 weeks. As already said it depends on battery temperature.

 

maybe I misunderstand the op but these are not my experiences.
(1) I put my foot on the brake and press the 'engine start' selector *twice*. the car starts up in hybrid mode by default. select reverse, lift foot from brake and roll out of the garage no problem.
(2) I put my foot on the brake and press the 'engine start' selector *once*. then use the eminihand to select any drive mode (qual/perf/hybrid/ed -- ed in this case), select reverse, lift foot from brake and roll out of the garage no problem.

in both cases above, when selecting a forward gear, the ice stays off and I continue to run on just battery. this works when the ice is either cold or hot.

I can start mine fine in E Drive, I press the start / ignition button once, then I press "Ed", then press the start / ignition button , I hear the Wizz noise of the electric starting and can immedistely drive away in E Drive mode. I do not need to start it in Hybrid or any other mode first.
Hope this helps
