[2019 fusion 2.0]

This doesn't look like a serious problem. If you are about to fix it by yourself, try to start with searching "fusion p2450" on youtube. Sometimes you just need to check all the pipings, sometimes to clean or replace the valve itself. But overall, this issue is quite common among various cars - no worries.

Unfortunately I'm still waiting for my 2017 Fusion to be delivered, so cant check this now. BUT it seems like these bulbs can't be replaced like any other bulb. These LEDs are part of the whole dome light so you should have some soldering skills to replace them. Despite this light looks like halogen, these are LEDs.

Thanks for your detailed post and photos! ? I'd like to expand this topic with some theoretical thoughts:

- Some of the LED lamps already have these resistors and marked with "CANBUS"

- You can use different nominals for resistors between 150-1000 ohms starting from 0.25 watts. Less power (watts) - more heat on resistor, more resistance (ohms) - lower power consumption on a resistor. But there is a chance that resistors more than 500ohms may be useless.

- This tweak in fact disables your lamp health monitoring system and you will not be notified when this particular lamp would die.

In addition to previous response, here is a small report for the vin you have provided. There are no service records (which happens for this type of report), but it is better to see a carfax for sure. AND! This car could be a rental vehicle!
