2018 Land Rover Range Rover problems

The dealer's Service Manager also confirmed in writing that drained oil is not examined for metal contamination as part of their standard oil change procedure. A…”

“The contact owns a 2018 Land Rover Range Rover. The contact stated that while driving at an undisclosed speed, the message flashing forward alert not available, brake assist not available, transmission fault, AEB not available, HDC not available were displayed.

The vehicle was taken to the local dealer and was diagnosed with engine failure. The engine was replaced, but after retrieving the vehicle, the failures immediately reoccurred. The vehicle was taken back to the dealer. The cause of the failures was not yet determined. The failure mileage was 67,000”
