The BMW X5 has been in manufacturing for the reason that early 2000s. It’s the primary SUV the model dropped at market, and wasn’t instantly a important success. That tune has modified via the truck’s quarter-century run, because the model obtained higher acquainted with constructing SUVs and buyer expectations. In actual fact, the BMW X5 is persistently one of many model’s high 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 whole world gross sales. Because the X5 ages and depreciates, it turns into an much more thrilling prospect for consumers making an attempt to ostensibly get probably the most for his or her cash. Let’s simply say some generations are a safer wager than others.
First Era BMW X5 (E53)
The primary era 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 gasoline 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 “previous BMW” issues (repeatedly changing the coolant system, DISA valve, oil filter housing gasket leaks), the M54-powered X5 is actually probably the most dependable of the primary era X5.
In the event you completely should have a V8 in your first-gen X5, the early M62 V8 (2000-2003 mannequin yr) is the safer wager. After 2003, BMW caught the N62 beneath 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 except it’s an M62.
There are a selection of different persistent points that maintain the E53 again from being thought-about one of many extra dependable methods to pilot an X5. Since they’re all all-wheel drive, there’s inherently a bit of 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 could be a troubleshooting nightmare. Choose up an M54-powered E53 with a stick shift for added novelty and probably the most dependable expertise potential (typically).
Second Era BMW X5 (E70)
The second era 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 obtained is dubbed the M57, and it’s a reasonably stout mill — so long as you’re prepared to shell out hundreds of {dollars} to maintain the emissions management programs operating easily. There are methods across the system, in fact, however you’ll want to search out these discussions elsewhere.
In the event you’re sticking with gasoline energy, there’s excellent news. The E70 obtained a ton of nice engines all through its life cycle, together with the wonderful 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 stick with it the custom of resilience. One other wonderful inline-six obtainable to E70 consumers is the N55. Primarily, you’ll be able to 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. However it’s not with out flaws: cost pipe failure is a close to assure, and over a protracted sufficient timeline you’ll probably have to confront points surrounding the high-pressure gasoline pump (HPFP), oil filter housing gasket, and cooling system (notably the water pump).
Three totally different V8 engines present up beneath the hood of the second-gen X5: earlier 4.8i/xDrive48i fashions obtained an N62, whereas later E70 vans obtained 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 keep away from N62-powered fashions. The N63 and S63 introduce turbocharging, which is a portion of why we are able to’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, not less than eliminates the turbocharger points, and is mostly considered as extra dependable. With regards to the second gen X5, we’re extremists: stick with a fundamental N52-powered automotive or full ship on the S63-powered X5 M; there are higher choices elsewhere within the X5 lineage for middle-grounders.
Third Era BMW X5 (F15 and F85)
The third era of the BMW X5 was produced from 2013 till simply 2018. Regardless of the quick run, there are a dizzying variety of choices to select from. Together with gasoline 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 primarily based 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 except you have got both of these choices at your disposal.
The hybrid X5 xDrive40e is attractive, because the PHEV depreciation curve is steep, and you possibly can save a bit of bit on gasoline. Nevertheless, 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 simple mannequin to analysis, both. On the very least, a superb guarantee is suggested. The N55 is essentially a carryover engine from the earlier era. Nevertheless, 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 latest 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 superb decide general.
Total, the third era BMW X5 has loads going for it when it comes to reliability. Whenever you additional think about an obtainable rear-wheel drive configuration (N55-powered automobiles solely), additional decreasing the variety of issues you’ll be able to break, it seems to be like a compelling alternative. And, in reality, we expect it’s: buying a third-gen X5 is about as protected of a wager as you may get, notably if you happen to don’t have the cash for a brand new one. Notably, it’s additionally the primary era not utterly affected by the dreaded Takata airbag recall (affected mannequin years minimize off at 2014).
Fourth Era BMW X5 (G05 and F95)
The most present X5 era can be probably the most dependable. The star of the present is the B58 inline-six, obtainable 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 thousands and thousands of BMW automobiles, making elements plentiful and analysis simple. A rear-driven B58 G05 X5 will take you very far, and now we have no reservations about recommending it as probably the most dependable X5 you should buy. The N63 returns with much more substantial modifications that make it, too, probably the most dependable iteration but; in fact, as some could already know, late V8 fashions (X5 M60i) ditch the N63 totally in favor of an S68 lifted straight out of the M fashions. Sadly the S68 is a bit of bit too new to have concrete information factors; we think about it will likely be fairly stout, however the built-in gentle hybrid parts may make repairs costly.
Because the PHEV fashions on this era depend on a B58 as an alternative of the previous 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 interchange and discovering somebody aside from the supplier prepared to work on it may be tough 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 Era is the Most Dependable?
Typically, the latest X5 you’ll be able to afford is probably the most dependable. We predict the second-generation X5 is on common the least protected wager, though it’s very shut between the primary and second era. The good factor about X5 reliability, general, is that points are principally confined to what’s beneath the hood. Inside high quality and even iDrive parts appear to have a low failure price throughout the board, though older fashions will probably nonetheless profit from a window regulator checkup earlier than shopping for. In the end, any BMW X5 could be a reliable automobile with correct upkeep and an intensive inspection earlier than buy, particularly when choosing one with a powerful service historical past. Maintain out for a superb one and also you gained’t be disenchanted.
