Sounds like a tooth has fallen off the single-speed reduction gearbox, or a main bearing has broken up somewhere, maybe in the motor itself & the rotor's now grinding away against the stator. Could just possibly be a CV joint broken up internally, or perhaps a wheel bearing or differential.
Not a lot else in there tbh!

That doesn’t sound good for a very low mileage car, hopefully they’ll sort it quickly for you.

Lots of Ioniq info in ioniqforum.com but I haven't seen this particular problem mentioned in there, on the 38 or 28. I think it's a very rare thing, and it wouldn't put me off in the slightest. I've had a driveshaft just fall off my pretty-new Golf GTi some years ago! Someone forgot to tighten up a critical nut or 2. Also had our Peugeot 107 stop with a bang at 30k miles, when the clutch release stuff just broke up. But that was a design fault, fixed by upgrading to clutch from Yaris instead of the original flimsier Daihatsu item. So any car can have this. Rolls Royce once had a driveshaft snap, and RR flew a new one + technician somewhere to fix it. "RR driveshafts don't break, sir!" or similar message from the techhy!

Remember EVs have less to go wrong on them, single reduction gear and all that jazz. But a single reduction gear is still components and can still have failures. Hopefully it can be resolved quickly for you and hopefully not stopping as soon as happened hasn't caused more damage. 🤞

Hi
just a further update got my car back today all fixed or seems ok at the moment garage said it was the eecu electronic control unit that sits at the top under the bonnet,controls everything,
so all good but the shocker was the final costing,the part alone was £15900 and total bill including new coolent was over £18000 i couldnt believe it its half the cost off the car,just lucky it was all covered under warrentry,
they said its the only one they have ever seen with that problem.

Wow, that would hurt if you had to fork it out. Appreciate you have been unfortunate and its probably a rare occurrence but still a sobbing thought (and I'm not knocking anyone) for anyone who thinks that there's not much to go wrong with an EV.

On the subject of warranty, does anyone know where the Hyundai document is that details how long each element of the car is covered for?
