For LEDs, there WILL be bulb outage errors, but it is not that bad.
I have tried with three different LEDs, hikari, opt7, and oxbeam. All of them show error. There is no way out of those errors except HID.
I've had these amazing OPT7 ones for couple of months now on my 2018 elantra SEL.
These are as bright as my HID on a mazda, but whiter, although both are 6000K. HID link below for comparison.
Although there are bulb out warning in the dash with LEDs, I've managed to ignore them. Initially it was irritating, but withing a week, I started not noticing it any more. With just a click on the ok button on the steering (as soon as I switch on the car), the warning goes away and my default speedometer comes back on.
I supposed you could use HIDs, but that would require drilling through the dust cap, and I don't want to scratch any OEM item.
I'd strongly suggest you to try the LED for a week and see if you can be habituated with the warnings.
