I very much doubt it’s your car but if it is and it’s the wrong spec, don’t accept it. Hyundai is about the only manufacturer to have built up a supply of semiconductors (all the others relying on ‘just in time’ supply chains, which have now caught them out) so you shouldn’t have to wait too long for the proper car. Hyundai don’t allow a wide choice of optional extras and, as a result, are one of the few manufacturers to build cars speculatively, whereas many other manufacturers are almost all bespoke factory orders. So, in summary, there’s no need to accept the wrong car but I strongly suspect you will get the correct one!
