So I checked the box to have the heated seat come on whenever the car starts. When I 1st did it, everything was fine. Then suddenly the heated seat will only be on when I start the car maybe 1 out of 5 starts.
Didn’t realize you could check a box to have the heated seats come on automatically. I was wondering why it felt like the seat was warmer than normal a couple days last month when I hadn’t turned the seat on. Thought it was just my imagination, lol.
My passenger seat heater turns from high to low to off in about 5-10 minutes every time I try to use it, no matter what the outside temperature is. The driver seat heater stays on high for as long as I want, no problem. Does anybody else have this problem with their 2018 Ghibli S?
Unless I am missing something, I didn't think there was a hi-lo setting for the seats. I believe mine are on and off. I thought this was strange, maybe I am missing something? I do wish there was a hard button for the seats vs. drilling into MTC.
EDIT: I see it in the manual. Maybe I just didn't see the high low. In terms of the auto on feature, I like it, but I wish it would shut off earlier or switch to low.
the seats operate off of amperage draw measurements to determine seat temp. max operating time is 4-6min boost, up to 60min high, up to 45 min low. it steps it self down automatically until off.
there is a broad range of conditions contributing to the system, including the biometrics and metabolism of the occupant. its overly fancy and dumb at the same time. also, the module controlling it is under the driver seat, shortest wiring on driver seat as such. the longer wiring to other seats contributes some resistance to the circuit and as such, disables/steps down the further seats quicker.
the only things that can cause the seats to operate differently is influence of resistance in the circuit, either through resistance in the wiring/connectors along the way to the heater element or the resistance of the bottom and back elements being incorrect and causing incorrect logic from the ECU responsible.
Thank you so much for your answer! I will bring up your comments to Maserati Corporate, if and when they contact me back. So far the two dealerships and Corporate have just blown me off, saying there's nothing they can do, unbelievable!
My problem is with the passenger seat heater, stays on for only 5 minutes, then shuts off on its own. 2 dealerships have looked at my car and couldn't fix it. Car was in the shop for weeks, Maserati Corporate says there's nothing wrong with my car. It's been over 3 months now and I'm back to square one, not sure what to do next. I hope you have better luck at a dealership and get them to fix your seat heater.
I have not encountered such a problem. But I rarely generally use heated seats
