2016 LAND ROVER DISCOVERY Unknown Or Other Problems

1.) WATER PUMP FAILED AT 21,000 MILES CAUSING COOLANT TO LEAK INTO THE ENGINE AND THE ENGINE TO OVERHEAT. 1 YEAR LATER CYLINDER #1 LOST COMPRESSION IN THE ENGINE MAKING THE CAR INOPERABLE AT 58,000 MILES. DEALER INDICATES THAT THE ONLY POSSIBLE REPAIR OPTION IS A NEW ENGINE AT THE COST OF $21K EVEN THOUGH THEY HAVE NO IDEA WHAT IS ACTUALLY BROKEN IN THE CYLINDER. THREE INDEPENDENT MECHANICS HAVE ALL INDICATED THAT THE WATER PUMP IS THE MOST LIKELY CAUSE OF THE FAULT IN THE CYLINDER AS IT MORE THAN LIKELY CRACKED A CYLINDER HEAD WHEN THE COOLANT WAS LEAKING. MY CAR FAILED WITH NO WARNING WHILE MAKING A LEFT HAND TURN ONTO A BUSY STREET, MAKING THIS A VERY DANGEROUS SITUATION. 2.) THE INTERNAL COMPUTER SYSTEM FAILED ON THE CAR, WHICH WOULD NOTIFY THE DRIVER REGARDING SERVICE, ENGINE TEMPERATURES ALONG WITH ANY FAILURES IN THE CAR'S SYSTEMS. DEALERSHIP...
