I have a 2021 Titan Pro-4x. I put a 1.5 inch Bilstein leveling kit on it and it looks great and I chose it because it would not negate my warranty. I have been getting the I-FCW caution light regularly since I had the leveling kit put on. I have brought it back to Nissan multiple times and they claim there is nothing they can do because the sensor is only made for the stock truck. I am pretty sure this is BS but I wanted to see if anyone else is having this issue. I have searched through the posts and I do not see anything.

Nah - this is BS from the dealership. I think @dubyam or @thebassn8tr are resident lift experts. The only thing you should have to recalibrate is the speedo, only if you put larger tires on it. The adaptive cruise, blind spot warning, automatic wipers, hi/low beams, all of that should remain unchanged.
I only offer advice off of personal experience and I have personally lifted a few 2021 Titans more than 1.5" and there were no issues with any sensors whatsoever.
Maybe you have a loose connection and they just never looked and blamed it in the kit.
See if the okygs are loose to the sensors or if there is dirt on the sensors

You should try a different dealer with a different story. Instead of saying it started after you installed the spacers, go with the story of, “a few weeks ago I noticed it coming on a lot more.” Let them figure it out. Electronics in any modern vehicle glitch.
I would think they'd have to prove it caused the issue. The writing is vague (intentionally), but they can't just say that. Too many lifts have been added for that to be the issue.
That dealer is crappy. Go somewhere else, but I'd tuck that lift story in my back pocket until it's fixed.

Just my experience with my 21 Titan. I’ve had my 1.5 leveling kit on for approximately a year. I had I-FCW light come on a couple of times, but would turn off. I believe the manual states that some environmental situations ie fog, excessive dust, dusk conditions could trip the sensors. But my truck has been good to go. My dealership also sells lifted Titans and service department is knowledgeable concerning lifting a Titan. Hope this helps.
When you mention certain things to a dealer you’re kind of feeding them something and they latch on to it. Logically what you did is insignificant to how the system should view the truck. I have zero alterations to my 2020 truck suspension wise and neither did my 2018 and both on occasion went/go stupid with that dash light. It stops just like it starts and nobody has a clue why. My truck has a squeal on start ups after it rains, it’s either the idler pulley or the belt tensioner but they make up a story as to why and fix nothing. I asked service if it’s an official Nissan position or did he just pull it out of his as$. Remember the service writer knows nothing about a car or he’d be working in the service bays.

Are you all talking about that red and white hazard warning light that flashes on the Info screen? If so, my 2020 PR does it randomly. It happens so fast and then goes away just as fast that I can't take a picture of if to show Nissan.
Re-calibrate the ADAS sensor. From the factory, your sensor may have been calibrated on the far end of acceptable range. The lift may have pushed the sensor range just outside of acceptable. The dealer [or a body shop] will use a diagnostic tablet and targets to perform the calibration.
