Reliability, common problems and owner reviews for the Bmw X5 xDrive48i (N62 V8). Check this before you buy used.
The N62 4.8 V8 makes the X5 rapid and sounds wonderful — but it's a famously expensive engine to keep right. The signature faults are valve-stem seals (telltale blue smoke on start-up/over-run), timing-chain guide wear, the alternator-bracket/coolant-transfer-pipe leaks buried under the intake, and very heavy fuel use. None are quick or cheap jobs. A pampered, fully-documented example can be reliable, but go in with eyes open and a big maintenance fund — for most buyers the diesel six makes far more sense.
