Model Year 25/26 Warning lights coming on then disappearing on dash

[Cupra Jon]

Bit of a weird one this - since Saturday I've been getting the yellow triangle appear on the dash along with front collision warning/SOS fault and lane assist lights appearing on the dash (the usual ones you get in winter when the windscreen camera or the radar in the bumper is obstructed with frost) only I'm not getting them ob start up, usually about 3-4 minutes into a trip and once I hit over 30mph...

Then the strange thing is they disappear a few minutes later... Windscreen and radar housing are both clean so this intermittent issue has me puzzled...

Take it to the dealer, let them check for faults

Yeah - done that now!

Had a total of 4 faults come up but managed to make a note of them before they disappeared...
SOS Emergency Assist
Travel assist is currently unavailable. Sensor impaired
Front assist is unavailable. Sensor impaired
ACC: Sensor impaired

Gonna also get them to do the update for the flickering ambient lighting issue that they should have done at the first service in March.

Did you face really hot wheather when this happened? We had similar orange triangle about DCC system.
We went to the dealer and DTC analysis just said 'overheating'... Since temps have cooled down a bit, it hasn't come up again...

Started about a week before the heatwave but interestingly there are about a dozen owners of Facelift Formentors reporting exactly the same issues over on the Formentor Owners Facebook page so I dunno. Interestingly I received an update from Cupra earlier this week and, once installed my errors all disappears so thats left me none the wiser.

That suggests the update fixed it?

I was out last week and my VZN did this with all sorts of pretty coloured lights so I stopped turned the ignition off for a few minutes turned it back on and it was clear and hasn`t done it again!
A case of modern technology electrical gremlins more trouble than its worth

Im booked in with my local dealer on 4th August to investigate the same list of issues ...I have been documenting times and distances travelled since 28th of June .... I have have the issues every day to varying degrees of time frame up to the 6TH July but have had no instances of this since 7th July , although this morning the Infotainment system failed to start when i went out . 3 ignition cycles of on/off with a 5 minute wait in between failed to clear it .

I had no option but to drive the car without the infotainment system active , and behold , it started 2 minutes into my journey ..
