Unfortunately, you are unlucky Alex. The software of the Macan is not its strongest point. I still find it strange that some cars have many software problems and others no problems at all. I have had my Macan for almost 3 months now and to date I have not had a single error message or malfunction. Fingers crossed 🤞

Agreed, same here.
Its very unfortunate for those who get completely stuck like that.
@Alex74 your best option is calling Porsche Emergency services.

I'm continuing to have the "seat belt unfastened" warning when I drive (and yes, my seat belt is fastened). Sometimes it doesn't come on at all. My last drive it was on the whole time. It's extremely annoying.

Just an update to this. I had two drives a couple of days ago where the "seat belt unfastened" warning was on the entire journey despite my seat belt being fastened. I bought a can of WD-40 contact cleaner from my local DIY store, and sprayed a generous amount into the female seatbelt buckle, and then fastened and unfastened the seat belt a few times. It immediately solved the problem and it hasn't come on since.

Hi all,

I was having this issue before the big software update a few months ago and it had been gone until yesterday. The right-sided speakers don't output music but work for system alert sounds and phone calls. Also getting all the assistance system errors like egress warning, parking assist, etc saying not functioning, visit dealership. I can compile a complete list of the assistance system failures in a follow-up post.

Also strange new finding is that charging at home overnight only charged at 3.9 kW when usually since taking delivery it's been around 9kW.

PCM reboot did nothing. Hoped leaving it off and locked throughout the day yesterday would randomly fix the issue but it's still there.

It seems the reboot with the volume button only reboots PCM but not the vehicle systems. Meaning, the center screen resets but the instrument cluster isn't affected at all and the alerts are there while the entertainment/nav systems are rebooting. Anyone know how to perform a soft reboot of the vehicle software other than just walking away and locking the car?

Thanks in advance.

I have only one small gremlin. When the car is started I get a yellow error light for the ACC on the dash. The first time I use the ACC the error light disappears and does not return during the trip when the ACC is toggled on and off depending on traffic conditions. The ACC seems to work fine but it kind of bothers me that something might be wrong with the ACC. Hope Porsche can resolve these issues.

In all fairness to Porsche I drove a Model S for 5 years and many updates were followed up with patches for newly created gremlins. The worst was when the error messages for the suspension kept chiming every few seconds because the system thought we were at a location where the suspension height was supposed to change. It got so bad one time that the car shut down the AC and controls! However, voice activation of the AC worked and then all the screen controls worked again. We are driving very complex machines.
