NHTSA Complaint #11578419 — 2016 LAND ROVER LR4

I took my 2016 LR4 (55k miles) in to the dealer in San Antonio a few days ago. As part of the review of my vehicle, they suggested that I should replace the cylinder block coolant outlet pipe, even though there is no current issue with or damage to it, for a cost of $2,042.13. They said that this part is "known for catastrophic failure around this mileage." That statement (about being known for catastrophic failure) is made not only in the repair estimate option selector portal but also somewhat emphatically by the technician in the walk-around video of my vehicle, and it was reiterated by the service representative ("We try to give people the option to replace the parts with the updated design since we see them fail so often."). If there is a part in the LR4 that, at 55k miles - on a well maintained vehicle with no apparent issue associated the part - is expected by the dealer to break and cause "catastrophic damage," that seems pretty clearly a safety defect that Land Rover should address, not me. I did not have the work done because, as stated, there is nothing presently wrong with the part other than that the dealer believes based on what they have seen that it is likely to break and cause catastrophic damage. But I am nonetheless very concerned that this part is going to break in the near future, presumably rupturing and releasing all of the engine's coolant, and cause some sort of serious incident and/or accident. I am attaching the estimate - let me know if you would also like the walk around video by the technician (it is very helpful but I am having a hard time getting it off my iphone, because of the size, even after editing the clip).
