Updated/New style (plastic) crossover pipe success/failures
That is in the timespan to be replaced if they haven’t been already. As noted in a post above someone had theirs start to leak at 89k. Also keep in mind the OEM aluminum pipes have only been available recently so an 80k mile vehicle may have had it replaced already with another plastic pipe. I’m at 55k without issue but do plan on replacing within the next 5k miles or so

My 2017 had about 74K miles on it when I replaced my cooling system parts proactively. I had never lost a drop of coolant. While the parts were removed one of them broke apart. It was ready to go.
I can't say whether it was the age (7 years at that time) or the mileage. But the fact that a failure can result in catastrophic engine damage is what prompted my preventative service. Note that the temperature sensor that would warn you of an overheating condition is located on a section of the cooling system that will not have coolant in it if you have a major leak. This means you could leak all your coolant and overheat the engine before your sensor warns you of a problem.
