The BMW X5 has been in production since the early 2000s. It is the first SUV to launch the brand and was not immediately a critical success. This melody has changed over the quarter of the century of the truck, since the brand was better familiar with the construction of SUVs and customer expectations. In fact, the BMW X5 is one of the brand’s top performers. In 2024, the X5 and its sportier twin sold the X6 275,318 units together. That is more than 10 percent of the brand’s global sales. With increasing age and the value of X5, it becomes an even more exciting view for buyers who are supposed to get the best for their money. Let’s just say that a few generations are a safer bet than others.
BMW X5 of the first generation (E53)
The first generation of the BMW X5, the E53, was in production between 2000 and 2006. All E53 X5S are all -wheel drive. On the US market, only naturally sucked gas engines were in the inline-six and V8 configuration, and the M54-inline-Six is the one you want for long-term durability. The M54 is a staple food of the BMW series. While you can expect some “old BMW” problems (regularly the coolant system, the disa valve, the oil filter housing sealing leak), the M54 provider X5 is certainly the most reliable of the first generation X5.
If you absolutely have to have a V8 in your first generation X5, the early M62 V8 (model year 2000-2003) is the safer bet. After 2003, BMW put the N62 under the motor hood of the models of 4.4i and 4.8is. The worst bundle is the N62, which often suffers from valve steam sealing failure, and astrent valve cover, time cover and alternating machine holder seals, coolant lids and SAI (secondary air injection system). The less complicated M62 also has problems such as Vanos problems and failed timing chain guides, but they are generally easier to plan to ensure through preventive maintenance. We would not recommend rolling the cube onto a V8 E53 unless it is an M62.
There are a number of other persistent problems that prevent the E53 from being considered one of the more reliable possibilities to control an X5. Since they are all all -wheel drive, there is a little more complexity than a two -wheeler version. All V8 models (and many inline-six models) have a form of an early air frame/self-level suspension (SLS), which can be a nightmare for troubleshooting. Take an M54-punch E53 with a shareholder for additional novelty and the most reliable experience (in general).
BMW X5 of the second generation (E70)
The second generation of the BMW X5, the E70, was produced from 2007 to 2013. Like its predecessor, E70 are only available in all-wheel drive, but the US market can finally enjoy a diesel engine. The diesel we have received is referred to as the M57, and it is a fairly thick mill – as long as you are ready to shake out thousands of dollars to keep the emission control systems smoothly. Of course there are opportunities in the system, but you have to find these discussions elsewhere.
If you stay in gas power, there is good news. The E70 got a lot of large engines throughout the life cycle, including the excellent N52-inline-Six, the last of BMW, which sucked the six of the sucking ends from BMW. These 3.0-liter mills are successors of the M54-X5 and largely continue the tradition of resilience. Another excellent inline-six for E70 buyers is the N55. Essentially, you can exchange peace for a considerable body of power. The N55 in the E70 makes a little more than 300 hp and 295 pound foot torque. However, it is not without defects: charge pipe failure is an almost guaranteed guarantee. Via a long schedule, you will probably have to deal with problems with the high-pressure fuel pump (HPFP), the oil filter housing and the cooling system (especially the water pump).
Three different V8 engines appear under the X5 of the second generation: formerly 4.8i/xDrive48i models received an N62, while later E70 trucks received an updated N63 power plant. Then there is the first X5 m to use an S63. We recommend that you keep staying away from models with N62. The N63 and S63 introduce turbo charging. This is part of why we may not be able to recommend the N63 X5 as a reliable selection.
Falling turbos, high oil consumption and (again) missing valve steam steam steam dilution dilution make the N63 as much a headache as the N62. The S63, on the other hand, is at least eliminated the turbocharger problems and is generally considered more reliable. When it comes to the second gene X5, we are extremists: stick to a basic N52 car or a complete sending of the S63-powered X5 m; There are better options in the X5 line for mid-range.
BMW X5 of the third generation (F15 and F85)
The third generation of the BMW X5 was produced from 2013 to only 2018. Despite a short run, there is a dizzying number of options to choose from. Together with the options “Inline-Six and V8” from Gas (both turboch), BMW continued to offer a diesel and even introduced a plug-in hybrid 40e variant. The F85 chassis code identifies the second X5 m, which is strongly based on the standard F15 chassis. The diesel is upgraded to the N57 unit and resembles the M57 in the sense that the reliability depends on maintaining or rejecting the emission control system. We do not recommend it unless you have one of these options.
The Hybrid X5 XDRIVE40E is tempting because the PHEV depreciation curve is steep and you can save a little on gas. However, there are some pitfalls. While the N20 engine is quite reliable in this application, parts are still expensive and labor-intensive for the electrical components. It is also not a terribly simple model to research. At least a good guarantee is recommended. The N55 is largely a transmission engine of the previous generation. However, the N63 V8 recorded a significantly updated N63 (“N63TU”), which increased the performance figures and significantly changed the power of the engine. A litany of new parts actually makes it worth considering here; Although failed turbos and valve trunk seals remain. The X5 m (here called F85) also uses another updated S63, the S63B44T2. Practically only a few changes – it’s still a good choice.
Overall, the third generation BMW X5 has a lot to offer in terms of reliability. If you continue to consider the available configuration in the rear wheel drive (only N55 vehicles), which further reduce the number of things you can break, this looks like a convincing selection. And in fact we think it is: The purchase of a third generation X5 is roughly as safe as possible, especially if you don’t have the money for a new one. Remarkably, it is also the first generation that is not fully affected by the dreaded Takata -Airbag recall (affected model years that were cut off in 2014).
BMW X5 of the fourth generation (G05 and F95)
The latest X5 generation is also the most reliable. The star of the show is the B58-Inline-Six, which is available I the X5 XDRIVE40/SDRIVE40 models. The B58 not only proves to be more reliable than the N55 predecessors, but also in the literally millions of BMW vehicles that make parts of plenty and research easier. A B58 G05 X5, driven after it, leads you very far and we have no reservations to recommend it as the most reliable X5 that you can buy. The N63 returns with still significant changes, which also make it the most reliable iteration. As some may already know, the N63 models (X5 M60i) naturally fully triggered to get an S68 directly out of the M models. Unfortunately, the S68 is a little too new to have concrete data points. We imagine it will be quite strong, but the integrated mild hybrid components can make repairs expensive.
Since the PHEV models in this generation rely on a B58 instead of the old four-cylinder, they are still an attractive view. While early reports tend to be reliable, we would be careful: battery components are expensive to replace and find that find a person other than the dealer who is ready to work on it, depending on where they live. The F95 X5 M uses either the S63 (2020-2023) or the S68 (2024+) engine, which we have covered elsewhere.
Which BMW X5 generation is the most reliable?
In general, the latest X5 that you can afford is most reliable. We believe that the second generation X5 is the least safe bet on average, although it is very close between the first and second generation. The nice thing about X5 reliability is that problems are mainly limited to what is under the bonnet. Interior quality and even iDrive components seem to have a low failure rate on the entire card, although older models will probably still benefit from a shop window regulator before buying. Ultimately, each BMW X5 can be a reliable vehicle with proper maintenance and a thorough inspection before buying, especially if you choose you with strong service tests. Consider a good one and you will not be disappointed.
