With apologies to The Platters....
So, last week the PCS2 on my 2024 Foundation Series AWD Cybertruck (June 2024 build, 19K VIN) was replaced. I received the new T2-G version, along with the round ferrite cable. No issues. The truck drove fine when I picked it up; and was back to its normal 32-amp L2 charging when I got it home.
A couple days and a couple hundred miles later, while traversing one of the remote, 60-mile rural loops that I enjoy several times a week... I suddenly hear a loud crack - probably about the volume of a .22 rimfire - from the right side of the cabin. Immediately followed by a billow of dense, acrid smoke coming from beneath the front passenger seat. The smoke had a clear electrical odor and was dense enough that for several seconds I thought there might be a fire.
Fortunately that wasn't the case. After rolling down the window, the smoke rapidly cleared.
The truck continued to drive normally. No alerts. No nothing.
Thinking that there's not really anything electrical under the front passenger seat except for the DC power supply that I keep up in the rear, under that seat supplying 12v DC for the cabin, I surmised that I had blown a capacitor in that DC supply. Either that, or maybe the VHF/UHF ham radio that sits right next to it.
So I was surprised when I pulled over at the first opportunity, about five minutes later, and walked around to find that everything with that equipment seemed fine. I sent a quick squawk to the local 2m repeater - the transceiver was transmitting and receiving exactly as expected; as was the refrigerator in the back being powered by that same 12v DC supply.
The 30-minute drive home was uneventful. As soon as I parked I went into Service Mode. This event happened on 7/5/26 at approximately 12:25pm. There was a VCLEFT_a096_HVBATTCON_MIA error, but its timestamp was roughly 35 minutes before the event. And its related icon suggested an airbag issue, if there was any issue at all (most Service Mode alerts are transient/spurious). So I concluded that whatever had happened was probably related to the restraint system in that front passenger seat, notwithstanding that that single _a096 error had occurred prior to the bang/smoke (if anything, that error may have presaged whatever ultimately caused the bang/smoke event).
Plugging in, the truck again received its L2 charge exactly as expected.
Service Mode ~35 Minutes After Event
A day and a half later, on 7/7/26, not having driven the vehicle since the event, I again went into Service Mode. There were a bunch more _a096 faults.
Service Mode Two Days After Event
This time, though, I peered under the front of the front passenger seat (looking for scorch marks or other evidence) and found that there are, indeed, a number of electrical components under that seat.
Beneath Front Passenger Seat
I submitted a service ticket. But it's three weeks away.
I'm still inclined to think this is a passive restraint system issue. But we'll see. I'm going to take the truck out today for the first time since the event, and we'll see if anything blows up.
Fun times!
