F12 Wont Start (2015)

Looking to see if any one has had this issue:

Background: Car was in storage for 5 months with the trickle charger on it. Started right up no issue at all. Drove the car numerous times after that.

Had to go out of town for a week, put on the trickle charger. Got back, put the key in etc car did its usual diagnostic all lights on etc, hit the start key and NOTHING. No sound nothing.

Will call the dealer on Monday to toe the car in but wanted to know if anyone had this issue?

 

I've had similar. Take the charger off. Let it sit for an hour or so. Then put the charger back on for 20 minutes. Took the charger off and it started.... What I did was not scientific but worked none the less. good luck.

 

are u sure you took the charger off? what u described it is exactly what happens when u try to start the car with the trickle charger still plugged in

 

Rmitchell, I did try that but no luck.

Ttforcefed, do you really think that I would leave the trickle charger plugged in? Not my first rodeo or Ferrari. But thanks for the suggestion.

 

well having little kids has made me do that multiple times.

it's possible the break pedal sensor is going - try standing on the brake pedal with all ur weight and see if that does the trick - happens on the 430s all the time

 

Question - is it giving you signs of low voltage? (dimmed lights, relays clicking away like mad, etc?).

Assuming you've done all the things you've learned in the "ferrari rodeo", the battery (I.e. voltage and current) are always prime suspects.

Another "it worked for us" item is to do several lock/unlock cycles....lock it, wait a minute for system/immobilizer to arm, then unlock.

Also I would try the reconnection of the tender and disconnect, for some reason it might be sensing it's still connected (residual/static?)

 

If you can get to the battery I'd try a disconnect / re connect next.

 

I said it last night in a 458 thread - these cars are getting to the point where they need a control alt delete button reboot

 

well, the batteries do have quick-disconnects on them, it might be a hint....though in the last 4 years across multiple Ferrari's, I've only had to resort to that once (brand new F12, driving out of the showroom, TFT's went dead). Our first 458 had a faulty battery, so even a reboot did squat.

Assuming everything else is good, only reason I can think of for the start button to be dead is a lockout (tender detected, security system) or simply not enough juice to get the starter engaged. Looking to learn what the cause is

 

yeh only other thing ive encountered is the break pedal sensor I mentioned - when those start to go you literally have to stand on the break pedal with all ur weight - that was a neat trick I learned from Henkel at miller

 

I tried the hard force on the break pedal and yes it started.

I will try it again without as much break pressure and see what happens.

Thanks for the idea.

There was no low voltage indication.

 

oh good to hear - just get the sensor replaced - don't mess around with that

 

Brake, not break, gentlemen.

again I blame my kids....50/50 isn't bad

 

In this case, perhaps break fits the bill...

 

Interesting about the brake sensor

 

My F12 "infotainment" system reboots itself every 10 minutes or so while driving -- no button needed!

 

Very interesting info...often my 458 doesnt want to start...I panic...try everything I can think of and it starts.

I have an old BMW I can leave unplugged in for 8 months and it always starts right up. Frustrating.

 

then drive the Beemer ... not as bad as a Prius but still a Beemer And today I am working on getting a Fiat 500L battery replaced, my daughter's car, we will see what the local service center does but so far it is bad as they have not returned my call for over an hour.

 

I do love that BMW...it's awesome.

 

Same, unless it randomly freezes, or mutes the guidance speech but still mutes the then playing audio source. This is after the latest NIT software update campaign - if anything that makes it worse.

 

Our F12 had a factory software update for the INT, it was made available about 2 months after we got the car and cleaned up some of the "bugs"....

Might be worth confirming that your cars have the update. I'm going to speculate and assume that the updates were market-specific (eg. in US, you have SiriusXM SatRadio, other markets have different setups).

Might have nothing to do with your issue(s), but we had similar issues before....and they were cured after.

 

had the same problem with my 458, tried and tried and tried and was so pissed off I really pushed the brake pedal down and bobby bingo she fired in a heartbeat.

 

you're welcome!

 

Update: mechanic checked the brake sensor and found no issues. He said at times you need to put greater pressure on the brake.

As FYI, he said when you start the car, the mechanical system first makes sure it's the right key and then the brake is depressed.

Thanks everyone for your input. Very helpful.
