mine were streaky from the beginning and given how often it rains here in the NW I had Lucid change it to a brand new pair only for the issue to remain the same! It was a bit of a challenge driving at night as the wipers left a streak for a brief moment (<1 sec) but in constant/heavy rain at night, that causes significant glare! However, all is not lost as I have found that you can replace just the wiper inserts (i.e. the rubber part) very easily with nothing more than a small flat head screwdriver and scissors (for cutting the blade insert to size). This is assuming that there is actually nothing else wrong with your wiper (e.g. nozzle jets still work as does heating). The end cap of the wiper come off easily after pressing a tab marked by an arrow. Then the rubber blade can be slide off and replaced. I bought my wiper inserts from Amazon (note: you need 5mm base for the inserts) for about $10-15 for a set of 10 inserts, or so. The tricky part is doing this without removing the wiper blades themselves as that is a very challenging thing to put back on as you'll need to rejoin the fluid nozzle and electrical for the heater. For me, I climbed into the frunk and accessed the driver blade this way. The passenger is much trickier to do as it doesn't fully extend with the frunk lid opened or closed so you have to replace with it only be partially retracted. Overall, once you know what you're doing, I'd say it is a 5-10min job.
