Buenas a todos,
Ayer iba circulando tan tranquilo i perdí toda la potencia del coche, el acelerador no respondía i el coche seguía teniendo luz y todo no era nada de la batería cambie varias veces de marcha y nada, cuando lo apague ya no volvió a arrancar, hacia el intento y nada, parecía que no había inyección de gasolina, he leído que suele pasar a los que fueron fabricados en 2021 y 2022 pero el mío es de 2024, no se si alguien tiene alguna idea o le ha pasado algo similar, pero me tiene algo preocupado aunque este en garantía.
 
Hello everyone,
Yesterday I was driving along peacefully when I suddenly lost all power to my car. The accelerator wasn't responding, and the car's lights were still on. It wasn't the battery; I shifted gears several times, but nothing. When I turned it off, it wouldn't start again. It tried to start, but nothing. It seemed like there was no fuel injection. I've read that this often happens to cars manufactured in 2021 and 2022, but mine is from 2024. I don't know if anyone has any ideas or has experienced something similar, but it's worrying me, even though it's under warranty.
can you confirm if you owned this since new and there is no aftermarket pedalbox?

there was a common problem with fuel pumps dieing. there was a recall and most i20N with the issue either failed already, or had their pumps replaced under warranty recall. 2024 cars would not be affected by this pump issue. is your vehicle build in 2024 or 2023? i'm not sure what date the pumps started being different out of the factory, but i think* mid-2023? (my 2024 built MY25 is fine).

if car doesn't start and idle then its likely still a fuel issue. pedalbox issue (if you have one) wouldn't stop engine from starting and idling. injectors normally foul or cause roughness before complete lack of power. despite supposedly not being in the scope of the known fuel pump issue, you could still have a dead fuel pump.
