NHTSA Complaint #11577059 — 2018 LAND ROVER RANGE ROVER SPORT

My family and I were driving home in my 2018 Range Rover Sport, which I purchased in 2019 from Land Rover of Sudbury (Massachusetts). A brief “coolant level low” warning flashed on the dashboard for less than a minute, then promptly went away and never flashed or displayed again. Minutes later, the car started shaking, forcing us to pull over onto the side of the Massachusetts Turnpike. The engine then immediately began smoking. The temperature gauge never went above the midpoint level, so we were quite confused about what the problem was. We had the car towed directly to Land Rover of Sudbury. They informed me that the engine needed to be replaced. I find it unacceptable, and most importantly, unsafe, that the car would go from a “Coolant Level Low” warning that lasted mere seconds before disappearing, to ZERO coolant and a catastrophic engine failure minutes later while driving on [XXX] This all happened only a few months after the vehicle had ostensibly been deemed to be in suitable repair by Land Rover of Sudbury upon my re-taking possession of it following 6+ months in their service shop. I still have not received any answer whatsoever from the dealership as to what went wrong with my vehicle. I have serious concerns that this could be evidence of a more pervasive issue that could potentially affect other vehicles that are currently on the road. I also question whether the service performed to the vehicle at Land Rover of Sudbury in 2023 was the cause of the issue. I question the sensors in the vehicle, as well as the communication to the dashboard, and I would like this fully investigated. Why would the coolant level low warning have gone off so quickly after it came on if there was NO coolant? Why would the temperature gauge on the dashboard not have elevated if the car was overheating? All of these questions lead me to the belief that something was wrong with the vehicle beyond what has been conveyed to me so far.
