Yelp, it happened to me.

Today we went for a nice drive just to see the leaves changing colors. After stoping for lunch, when we got back in the car the infotainment was extremely slow to boot (3-4x the normal time). Thinking it just did some kind of AAOS update or something, we went on with the drive.

About 45 minutes later all the screens starting going black. First the passenger display, then the center console, then the dashboard, and once the dashboard was showing the speed again the HUD went down too. When they came back online, the infotainment would not respond to touch inputs at all. The physical controls on the wheel and the center console worked, but no control via touchscreen on the center or the passenger display. At this point I'm pretty nervous, but we try rebooting the infotainment by holding the power button for 20s. When it comes back up the touchscreen works, but if very sluggish.

About 5-10 minutes later, I get the Christmas tree on the dashboard. Every warning imaginable starts cycling through, including "chassis failure: safely pull over and shutdown the car", "assistance systems limited", "tire pressure monitoring failed", and a bunch of others, as well as every warning / error symbol in the cluster. We pull into a parking lot and park away from everything else (in case a tow truck has to load the car), and before I even put it in park the dashboard goes blank again. The infotainment (both screens) is still frozen. Soon after the HUD goes dark. At this point I put it in park (which thankfully works), we shutdown the car, get out, lock it, and leave it for 20m.

When we go back to the car, it starts up fine (slower than normal, but faster than after lunch). We set the route back to the Porsche dealer, and when it says the directions the voice is actually a bit raspy. Thankfully it's a pretty straight shot to get to Porsche, and nothing happens on the way.

Even though I showed up without an appointment, when I explained what happened they took the car immediately and had Uber take us home. I figure I'll hear from them late Monday or Tuesday with the initial diagnosis.

Including all the things that happened to my car, this ha as well happened. It was while my wife was driving to the store, started it up and went into Reverse, the whole car stop working with red chassi warning and about 10-15 other errors that happened at the same time. In our case, miste of the errors that came up had been happening in single incidents before.

They found over 100-200 error codes, didn’t find a solution but had a car in for a few weeks, went downhill from there. That being said, they might want to hand the car over by stating that ”we can’t find the errors anymore and test drove the car”, because they don’t know actually why it happened. Don’t listen to them, ask for detailed explanations to why it occurred and what they did to solve the issues.

They sent me back many times, and the issues kept adding up. Long story short, car has been at the dealer for 10 months waiting for a so-called ”big update” that ”might solve” the solution they don’t even know how to fix.

THIS IS NOT TO DISCOURAGE YOU AT ALL. I just want to give you a worst case scenario so you don’t listen blindly to the dealer, this isn’t something normal.

Sorry to hear, a mum from hockey had similar problems a few times (she didn’t mention Xmas tree though). Dealer brushed it off and when I asked mine, same group but main hub for electric Porsche service, they never heard about this. I posted a technical note from Porsche a few days ago, they are very well aware of all sorts of problems.

If dashboard goes dark while driving, that’s a serious problem. Here in the UK that would have been an offence if you would have continued to drive. Hockey mum was on a school run! Responsibility is with you as a driver. I agree, detailed technical information of what has caused the fault and how this has been addressed is a must IMHO but chances are, problem will never reoccur.

I am currently in Cumbria with 1h drive to first signs of civilisation. Extremely poor to no mobile reception. Will post my experience once I am back home. Experience depends on a) your own car and b) reliable charging infrastructure. 2 charging stations along the way were faulty, one due to blackout in the morning. Gas station was back to normal but no one cared to reboot electric chargers. My loaner works perfectly as does Porsche app recommending charging points. If not, I may have stranded.

Update: Got the car back this morning. As expected, no fault codes found and they couldn't replicate the problem. They did do the 3 open recalls on it (none of them software related). So looks like I just have to hope it doesn't happen again.

Fingers crossed. If it happens again, make pictures.

I actually wanted to, but couldn't get my phone out and ready fast enough after pulling into the parking lot. The cluster display shutdown so quickly after that that I couldn't get it.

Fair enough. I would write letter/email with summary of events to dealer so that you have evidence in case the error reoccurs. Much easier to point to something in writing.
