Is the 2021 BMW X5 reliable?

Owners rate it 4.67/5, a strong signal of long-term satisfaction.

User feedback points to a vehicle that feels dependable in daily use, with owners highlighting its smooth ride, safety features, and high-quality interior. The expert evaluation also notes that the X5’s cabin is quiet and its suspension soaks up bumps well, which supports the impression of a refined, trouble-free ownership experience. BMW’s plug-in hybrid version also adds the benefit of emissions-free driving for short trips, and the model’s charging setup is described as easy to use.

For used buyers, the main long-term ownership risk is cost: packages, extras, and higher-spec versions can make upkeep and running expenses climb quickly.

What should I look for when buying a used 2021 BMW X5?

Key things to evaluate:

• Trim level: Standard xLine models use matte aluminium grilles, satin-aluminium exterior accents, and full adaptive LED headlights, while M Sport styling adds body-colour trim, matte aluminium kidney grille bars, and a more aggressive cabin with an M sports steering wheel, M-specific pedals, a driver’s footrest, seat piping, and model-exclusive interior trim strips.
• Powertrain: You get a 3.0-litre inline six-cylinder with 335 horsepower and 330 pound-feet of torque in the xDrive40i, a twin-turbo 4.4-litre V8 with 523 hp and 553 lb-ft in the M50i, a 600 hp twin-turbo V8 in the X5 M, and a plug-in hybrid xDrive45e with 389 hp, 443 lb-ft, a 24-kWh battery, and up to 50 km of electric range.
• Safety package: Every X5 includes blind-spot monitoring, forward collision warning, automatic emergency braking, pedestrian detection, adaptive cruise control, front and rear parking sensors, lane departure warning, automatic high-beam headlights, and a rearview camera. The available Driving Assistance Professional Package adds adaptive cruise control with stop-and-go functionality, but the system’s lane-keeping and traffic response behaviour can be inconsistent.
• Infotainment: The standard setup centres on a 12.3-inch infotainment touchscreen, a 12.3-inch digital gauge cluster, wireless Apple CarPlay, wireless Android Auto, navigation, HD Radio, satellite radio, Bluetooth, five USB ports, voice recognition, a panoramic sunroof, proximity key, and remote start. Available upgrades include a head-up display, quad-zone automatic climate control, a wireless smartphone charger, ventilated and massaging seats, a Wi-Fi hot spot, and upgraded audio systems.
• Fuel efficiency: The xDrive model is rated at 10.4 L/100 km combined, the xDrive45e at 11.5 L/100 km combined on gasoline and 4.7 Le/100 km when using electricity and gas, the M50i at 12.7 L/100 km combined, and the X5 M at 15.7 L/100 km combined.

Which 2021 BMW X5 trim should I buy?

The 2021 BMW X5 is offered in 4 trim levels: xDrive40i, xDrive45e, M50i, and X5 M.

Here's the short version:

• xDrive40i: This is the entry point and the best-value choice for most shoppers because it gives you the core X5 experience with the standard six-cylinder engine, AWD, and the full base equipment list without pushing ownership costs into the higher-performance range.
• xDrive45e: Choose this if you want the plug-in hybrid version with electric driving capability, strong combined output, and the added flexibility of short emissions-free trips.
• M50i: This trim is for you if you want a much stronger V8 and a more performance-focused feel without jumping all the way to the full X5 M.
• X5 M: Pick this only if outright performance is your priority, since it brings the most power and the highest running costs.

Safety equipment is standard across the lineup, but the available Driving Assistance Professional Package has some real-world limitations you should test carefully.

Is now a good time to buy a used 2021 BMW X5?

This looks like a moderate, selective buyer’s market, so you can shop patiently and still find worthwhile listings.

• Deal availability: 31.1% of listings are priced as good or great deals.
• Inventory: There are 164 listings available.
• Price trend: Prices have softened 13.11% compared with last year.

If you find a listing below $44,663 CAD, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 BMW X5's resale value?

The current average of $44,663 CAD sits slightly below last year's $51,404 CAD.

That decline suggests the market has become more favourable for buyers, but it also means a future seller may need to price more competitively to stand out. If you buy well now, you may have less depreciation pressure than someone who purchased when prices were higher. The X5’s strong reputation for comfort, technology, and interior quality should help support demand, especially among shoppers looking for a premium family SUV.

Vehicles with strong owner satisfaction ratings, like this model year's 4.67/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 BMW X5 safe?

The 2021 BMW X5 has been given nearly all Good ratings by the Insurance Institute for Highway Safety (IIHS), and it has a four-star overall safety rating from NHTSA.

It earns a 6/10 safety score from our experts.

BMW equips every X5 with blind-spot monitoring, forward collision warning, automatic emergency braking, pedestrian detection, adaptive cruise control, front and rear parking sensors, lane departure warning, automatic high-beam headlights, and a rearview camera. The available Driving Assistance Professional Package adds adaptive cruise control with stop-and-go functionality, but testing showed that it could struggle to react smoothly to stopped traffic and that lane-keeping performance could be disrupted by sunlight and rain.

Should I buy a 2021 BMW X5 or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 31.1% of listings are priced as good or great deals.
• Price trend: Prices have softened 13.11% compared with last year.
• Owners rate it 4.67/5 — a strong satisfaction signal.
• For 2021, the SUV’s second-generation plug-in hybrid variant joins the family, adding more choice to an already broad lineup.

The bottom line: If you want the most up-to-date version of this generation with the plug-in hybrid added to the lineup, the 2021 is the one to target. If your priority is simply getting the best value, you can also compare nearby years and focus on whichever one gives you the right trim, condition, and price.
