The BMW X5 has been in manufacturing because the early 2000s. It’s the primary SUV the model delivered to market, and wasn’t instantly a vital success. That tune has modified by the truck’s quarter-century run, because the model bought higher acquainted with constructing SUVs and buyer expectations. In truth, the BMW X5 is constantly one of many model’s prime performers. In 2024, the X5 and its sportier twin the X6 offered 275,318 models mixed. That’s greater than 10 % of the model’s complete world gross sales. Because the X5 ages and depreciates, it turns into an much more thrilling prospect for buyers attempting to ostensibly get probably the most for his or her cash. Let’s simply say some generations are a safer guess than others.
First Technology BMW X5 (E53)
The primary technology of the BMW X5, the E53, was in manufacturing between 2000 and 2006. All E53 X5s are all-wheel drive. The US market solely noticed naturally aspirated fuel engines in inline-six and V8 configuration, and the M54 inline-six is the one you need for long-term sturdiness. The M54 is a staple of the BMW lineup. Whilst you can count on some “outdated BMW” issues (recurrently changing the coolant system, DISA valve, oil filter housing gasket leaks), the M54-powered X5 is definitely probably the most dependable of the primary technology X5.
Should you completely should have a V8 in your first-gen X5, the early M62 V8 (2000-2003 mannequin yr) is the safer guess. After 2003, BMW caught the N62 below the hood of the 4.4i and 4.8is fashions. The worst of the bunch is the N62, usually affected by valve steam seal failure, leaking valve cowl, timing cowl, and alternator bracket gaskets, coolant leaks, and SAIS (secondary air injection system) failure. The simpler M62 additionally has issues, like VANOS points and failing timing chain guides, however they’re typically simpler to plan for through preventative upkeep. We wouldn’t suggest rolling the cube on a V8 E53 until it’s an M62.
There are a selection of different persistent points that maintain the E53 again from being thought of one of many extra dependable methods to pilot an X5. Since they’re all all-wheel drive, there’s inherently a little bit bit extra complexity than a two-wheel drive model. All V8 fashions (and lots of inline-six powered fashions) have some type of early air suspension/self-leveling suspension (SLS), which is usually a troubleshooting nightmare. Choose up an M54-powered E53 with a stick shift for added novelty and probably the most dependable expertise doable (typically).
Second Technology BMW X5 (E70)
The second technology of the BMW X5, the E70, was produced from 2007 till 2013. Like its predecessor, E70s can be found solely in all-wheel drive, however the US market lastly will get to get pleasure from a diesel engine. The diesel we bought is dubbed the M57, and it’s a reasonably stout mill — so long as you’re keen to shell out hundreds of {dollars} to maintain the emissions management techniques operating easily. There are methods across the system, after all, however you’ll want to search out these discussions elsewhere.
Should you’re sticking with fuel energy, there’s excellent news. The E70 bought a ton of nice engines all through its life cycle, together with the superb N52 inline-six, the final naturally aspirated six from BMW. These 3.0-liter mills are successors to the M54-powered X5s, and so they largely keep on the custom of resilience. One other glorious inline-six accessible to E70 buyers is the N55. Basically, you possibly can commerce peace of thoughts for a substantial energy bump. The N55 within the E70 makes simply over 300 horsepower and 295 pound-feet of torque. But it surely’s not with out flaws: cost pipe failure is a close to assure, and over an extended sufficient timeline you’ll seemingly have to confront points surrounding the high-pressure gasoline pump (HPFP), oil filter housing gasket, and cooling system (significantly the water pump).
Three totally different V8 engines present up below the hood of the second-gen X5: earlier 4.8i/xDrive48i fashions bought an N62, whereas later E70 vans bought an up to date N63 energy plant. Then there’s the first-ever X5 M, which utilized an S63. We’ll once more suggest you avoid N62-powered fashions. The N63 and S63 introduce turbocharging, which is a portion of why we will’t probably suggest the N63-powered X5 as a dependable decide.
Failing turbos, excessive oil consumption, and (but once more) failing valve steam seals make the N63 simply as a lot of a headache because the N62. The S63, then again, at the very least removes the turbocharger points, and is mostly considered as extra dependable. With regards to the second gen X5, we’re extremists: follow a fundamental N52-powered automobile or full ship on the S63-powered X5 M; there are higher choices elsewhere within the X5 lineage for middle-grounders.
Third Technology BMW X5 (F15 and F85)
The third technology of the BMW X5 was produced from 2013 till simply 2018. Regardless of the brief run, there are a dizzying variety of choices to select from. Together with fuel inline-six and V8 choices (each turbocharged), BMW continued to supply a diesel and even launched a plug-in hybrid 40e variant. The F85 chassis code identifies the second-ever X5 M which was based mostly closely on the usual F15 chassis. The diesel is upgraded to the N57 unit and is just like the M57 within the sense that reliability is contingent upon sustaining or discarding the emissions management system. We don’t suggest it until you will have both of these choices at your disposal.
The hybrid X5 xDrive40e is engaging, because the PHEV depreciation curve is steep, and you possibly can save a little bit bit on fuel. Nonetheless, there are some pitfalls. Whereas the N20 engine is pretty dependable on this utility, elements for {the electrical} parts are nonetheless costly and labor-intensive. It isn’t a very straightforward mannequin to analysis, both. On the very least, a very good guarantee is suggested. The N55 is essentially a carryover engine from the earlier technology. Nonetheless, the N63 V8 noticed a considerably up to date N63 (“N63TU”) that drove up efficiency figures and considerably modified how the engine performs. A litany of recent elements make it really worthy of consideration right here; though failing turbos and valve stem seals persist. The X5 M (dubbed F85 right here) makes use of an additional up to date S63, too, the S63B44T2. Although, virtually, little modifications — it’s nonetheless a very good decide general.
Total, the third technology BMW X5 has quite a bit going for it by way of reliability. Whenever you additional think about an accessible rear-wheel drive configuration (N55-powered vehicles solely), additional decreasing the variety of issues you possibly can break, it seems like a compelling alternative. And, in actual fact, we expect it’s: buying a third-gen X5 is about as protected of a guess as you will get, significantly when you don’t have the cash for a brand new one. Notably, it’s additionally the primary technology not utterly affected by the dreaded Takata airbag recall (affected mannequin years minimize off at 2014).
Fourth Technology BMW X5 (G05 and F95)
The most present X5 technology can also be probably the most dependable. The star of the present is the B58 inline-six, accessible I the X5 xDrive40/sDrive40 fashions. Not solely is the B58 proving to be extra dependable general than its N55 predecessors, the inline-six has additionally confirmed up in actually tens of millions of BMW autos, making elements plentiful and analysis straightforward. A rear-driven B58 G05 X5 will take you very far, and we now have no reservations about recommending it as probably the most dependable X5 you should purchase. The N63 returns with much more substantial modifications that make it, too, probably the most dependable iteration but; after all, as some could already know, late V8 fashions (X5 M60i) ditch the N63 solely in favor of an S68 lifted straight out of the M fashions. Sadly the S68 is a little bit bit too new to have concrete information factors; we think about will probably be fairly stout, however the built-in gentle hybrid parts may make repairs costly.
Because the PHEV fashions on this technology depend on a B58 as a substitute of the outdated four-cylinder, they proceed to be a lovely prospect. Whereas early studies are likely to skew dependable, we’d tread fastidiously: battery parts are costly to exchange and discovering somebody apart from the seller keen to work on it is perhaps difficult relying on the place you reside. The F95 X5 M makes use of both the S63 (2020-2023) or S68 (2024+) engine, each of which we’ve coated elsewhere at this level.
Which BMW X5 Technology is the Most Dependable?
Typically, the most recent X5 you possibly can afford is probably the most dependable. We expect the second-generation X5 is on common the least protected guess, though it’s very shut between the primary and second technology. The good factor about X5 reliability, general, is that points are largely confined to what’s below the hood. Inside high quality and even iDrive parts appear to have a low failure fee throughout the board, though older fashions will seemingly nonetheless profit from a window regulator checkup earlier than shopping for. Finally, any BMW X5 is usually a reliable automobile with correct upkeep and a radical inspection earlier than buy, particularly when choosing one with a robust service historical past. Maintain out for a very good one and also you received’t be dissatisfied.
