[RESOLVED] Dreaded hybrid system failure

I guess I am an officially member of this elite club!! I have an early build 296 and 2 weeks ago while driving I got the pop up with the hybrid failure. Parked the car for 30 minutes and came back and everything was fine and all warning lights were gone. Car drove fine for the next 2 weeks.

Fast forward to yesterday, I decided to drive the car to the office, for a change. Got in the car and it wouldn’t start. Had power but immediately the below warnings popped up. It would make a very strange sound when I tried to hit start/stop for the second time (first click, everything powers up and cycles. second click to fire up the engine did nothing and all warnings triggered).

Called the dealer and they said they have not had a 296 with that problem yet. They said the earliest they can pick it up is late next week but if I can drive it to them that would be best. Left for work and came home later that day and tried again. Got the engine to fire up but immediately had the hybrid warning lights and the engine failure warnings.

I pulled the car out thinking I would attempt to drive to the dealer. Got a mile from my house and the warning lights were going crazy. Had 5 or 6 different warnings and various symbols pop up. (PEV failure, hybrid failure and lots of others), A/C went out and car wouldn’t shift. I immediately got it home and called the dealer. It will hopefully be picked up next week.

The hybrid battery is always full when I park and it is driven every weekend. I’m up to 850 miles on the car and typically drive it sat/sun for short drives. I left it on the charger overnight but it wouldn’t even charge (only 1 blue light would flash)

for those that have had this issue, what was the ultimate fix or problem?? Thanks for the help.

Ferrari recommends it be plugged in to extend the life of the battery. (From the manual) It is NOT a requirement. If not driven for more than 2-3 days than yes, I do plug it in. Ev battery is always full when parked, regardless. I asked another dealer about this and they said it has nothing to do with the issue. There are others that have had this issue when the car has always been on the charger when it’s not driven.

Chet, Have you had this issue, or any issues with yours?

 

Thank you and very helpful. Do you need to disconnect anything when charging the battery in the footwell? What type of heavy duty charger? I have a smaller one that is more like a trickle charger but will go pick up a different one today.

 

My car did not come so try the feature to connect to the app. Only thing that shows up is the car, warranty info. I think that feature was added later on

 

Guess I have the AGM battery. Also just tested and I’m at 12.85 V

No. Only tried performance mode. Will try quali mode and see. I have a feeling it is going to spend some quality time at the dealer while they try and sort it out.

 

I’ve Had it 6 months without a single issue/problem before this occurred. Hopefully it’s not too complex for them to fix. (I’ve tried to keep the new car separated so no one gets jealous )

 

I did! Just added the carbon sill kick plates earlier in the week. Didn’t even get to take the car out with them installed. Oh well.

 

So, an update and interesting news. I figured maybe I’d try and start up the car today and see what happens. All warnings gone except for “engine control system failure” pictured below.

Took the car to fill up with gas and everything appears to be operating fine. A/C works, it’s shifting gears, acceleration is normal. I filled up, came home and drove in pure EV for 2 miles and it was fine. The CEL never went away and interestingly as soon as I went from EV to qualifying mode the engine control warning flashed again but it still drove fine.

Very odd and not sure how safe it is to drive it a little longer. This trip was about 6 miles. I could use my OBD II scanner and clear the CEL but would rather the dealer check it out.

No power surge or power interruption at all.

 

Well, today’s update is not so good. Started the car and all warning lights off. I figured, great, maybe it was having a bad day and it fixed itself. So I took it out and got 4 miles away from the house and it lit up like a Christmas tree. No AC, wouldn’t shift, no blinkers, etc. luckily, I was able to drive very slow and made it home.

NOT trying that again and will wait for Ferrari to come pick it up next week or so. I will update once they have it and start diagnosing it.

 

What was the ultimate problem and fix?
