Ioniq5 Mileage Not Reaching 303 on Full Charge

I have been driving my Ioniq5 for about 3 weeks. When I first got it, it was charged up to close to 300 miles. Ever since the first week, the max I will get when the battery is at 100% is roughly 266 and now it seems to have dropped again to around 250 after receiving a full charge, I have used Level 1, 2, and 3 chargers since I got the car. Is anyone else experiencing this? The dealer said it was because it is an adaptive system but I don't know if that applies here???

I have the same issue. How can I plan for a long drive if the ioniq 5 does not fully charge to 303 miles?

The car will charge fully if you so choose. Whether you get 303 miles range, or not, is entirely down to how you drive. Wind resistance losses go up with the square of your speed, and these losses dominate energy use once above 40-50 mph, so they really matter. Secret is to drive gently to begin with, and see whether your "reserve" is steady (ok), or decreasing (bad news). If decreasing too quickly, you're not going to make your destination, so either slow down, or plan to stop en-route.

As it's a fast-charging car, why not stop after a couple of hundred miles, take on a quick topup and have a leg-stretch at the same time. Then you'll have plenty of reserve, there might be some motorway-blockage at the last moment causing you a big diversion, so it's not a great idea to push the limits too hard.

The car is fully charged when the dashboard shows the battery at 100%. How much range the car's software thinks you will get depends on the state of charge and its estimate of how much power you will use, based on your driving history. It does not mean that you can necessarily drive the estimated distance. You will not get as far if you drive with a lead foot, if its very cold, if your destination is significantly higher than your deparure point or if you're carrying a heavy load or towing a caravan. Conversely, if you see a low estimate because of one of the above reasons in your previous driving, you may actually be able to drive further than the estimate if you are driving more slowly/downhill/with less load etc.
I would suggest you plan your drive to the next charger to be no more than 80% of the estimate, that way you will have a buffer and be less worried. You'll also have an option if the charger you're aiming for is not working.

My RWD SEL 2023 is less than 2 months old. But driving at 70 mph means that it'll only go 265 miles with a full charge. For long trips (I have a 1,200-mile road trip coming up), you'll need to find a DC charger twice during the day and hope to be fully charged overnight to go 600+ miles. So get all the EV routing apps downloaded and start planning.
