Hi all, just purchased a 2018 Lusso T. 12,000 miles and great fun. I’ve driven it 4 times so far and on 2 of those trips—about 15 min in: - TPMS gives alert (though rears are 36 psi and so in range?) - TPMS gives failure - AC turns to heat (or defrost). Like full hot on floor, though no one touched controls. - outside temp fails. Shows only - - (dash dash) both times, after perhaps 10 minutes, the TPMS failure clears itself. AC works again and outside temp displays. has already caused a trip cancellation (no one wants to head to Palm Springs in Aug without 100% confidence in their AC!). open to any ideas! Will bring back to dealer of course. But sometimes forums have more to offer than techs in my experience
Is there any chance of low battery at start-up ie minimal use in the days before outings with just enough charge to start but then first few minutes with all the toys on discharges battery ?
As a new owner, I’m open to anything. But my gut says no as the second time it happened the car had been on Ferrari charger about 48 hours. I can’t say how long it had been since car last driven. The dealer also wondered if it was from disuse but I sort of dismissed as optimistic thinking as the failures were so unrelated I thought software issue or sensors or something. (What do TPMS, AC/heat & outside temp have in common??) But I admit new owner! Maybe it’s battery related? But then how does that explain a tire pressure warning at 36 PSI, which was the first link in failure chain both times….
So the battery is 4 years old already? I'm calling bad battery. It doesn't matter that you keep it on the tender - you have no idea how badly the battery has been abused before you owned the car. The Lussos also eat batteries as Ferrari, in its wisdom, chose to site them in the most inhospitable place possible - the engine bay. The heat absolutely kills them and shortens their life massively. I live in Northern Europe and my AGM batteries go off after two years. So I treat them as a consumable and change them every two years like wiper blades...
Is this the latest & greatest for our cars? https://www.autozone.com/batteries-starting-and-charging/battery/p/odyssey-battery-65-pc1750t-group-size-65-950-cca/832143_0_0?cmpid=LIA:US:EN:AD:NL:1000000:BAT:17474778361&gbraid=0AAAAADkcoVs2dsmHRKNQkL8Ua9IwrQwya&gbraid=0AAAAADkcoVs2dsmHRKNQkL8Ua9IwrQwya&gclid=CjwKCAjw6fyXBhBgEiwAhhiZshxyoRFwbYrdW2H-g6sM_jbjKAj5IRRnSzgWGvDg6-v9Dh1A5cB3xhoCtKAQAvD_BwE&gclsrc=aw.ds
Thank you all for the help so far.. Interstate only offers one battery for 2018 Ferrari’s per their site… this will work? Image Unavailable, Please Login Shows this option FYI:
The size for the FF is MTX-49/H8. I would guess it is the same for the Lusso. Edit: I just realized you have the V8, probably not the right battery size.
TPMS thing happened to me this year with my 812 GTS. I simply reset/reprogrammed the sensors and that fixed it. Did you try resetting TPMS? Sent from my iPhone using Tapatalk
The TPMS sensors are VERY sensitive in the 812, so I can imagine it´s similar for the Lusso. Mine regularly go off (usually the front tires) giving a pressure warning eventhough the pressure displayed didn´t change one bit. After a few minutes, the warning goes away. It usually happens when the trip is started with a little cooler outside temp. Once the tires get up to temperature the TPMS thing disappears. The reset only fixes this "issue" for a while. Dealer said it´s a known thing that the tire pressure sensors are "over sensitive".
I agree about the battery. The tire pressures can be found in the owners manual. However, I find most modern Ferraris like to have pressure around 32 when the tires are up to temp. The way to do this is drive around with a tire gauge, once you have driven a bit pull over and set the tires to 32. The display might be a little different- it might read 33 or 31. Some Ferraris read higher than a calibrated gauge, some read a little lower. Reset computer. Let the car sit overnight and check the pressures again- these are the ideal pressures for your car on these tires given how you drive. They might be a little different side to side. Write them down. Then reset the tire computer again. For the GTC4 Lusso V12 Ferrari recommends 34.8/ 33.4 psi. I think this is for a car fully loaded with passengers and luggage. I find this too high for when I am alone or with one passenger. Given my usual drive is 45-60 minutes and Im often alone, and my driving style, I set them to 28/29 and while driving along they will get up to 32/33 and stay there. If your pressures keep rising as you are driving, especially if you are not really on it, then they are too high.
