BMW X5: A data-led used car review

The BMW X5 is a large, premium SUV that blends performance, practicality and executive-level comfort. As one of the original luxury SUVs, it has long appealed to drivers who want strong road presence, refined long-distance capability and advanced technology [1].

In the used market, the X5 offers impressive performance and high specification for considerably less than its original list price [2]. However, as a heavy, technology-rich vehicle with powerful engine options, it takes 7th place on our Lower Reliability list for 2026, compiled using data from our Reliability index.

This does not mean problems are inevitable. Many BMW X5’s provide smooth, refined ownership when well maintained. However, the data suggests buyers should plan carefully for potential repair exposure, particularly as vehicles move beyond early ownership, alongside an extended warranty.  

With a full-service history, sensible ownership and planning for long-term running costs, many drivers continue to enjoy the BMW X5 with confidence. 

BMW X5 – Reliability Index data.

Metric	Typical figure*	What this means
Average age at repair	7.1 years	Issues tend to appear later in model’s lifespan
Average mileage at repair	74,646 miles	Average mileage for repairs in relation to wider Reliability Index.
Average repair cost	£1,847.70	Lowest average repair cost in our Higher Risk category. Higher than average overall. Reasonable for a premium SUV
Most regular repair area	Suspension	Special attention to be paid to this area if considering used purchase. BMW X7 also reports suspension as most regular repair area.
Highest recorded repair	£30,675.02	Extremely uncommon, highlights worst-case scenarios for major issues.
Reliability score	23.6/100	Indicates higher ownership risk

What our data suggests about used BMW X5 reliability:

Based on our historic repair data, the BMW X5 takes 7th place on our Lower Reliability list for 2026. A little sensible budgeting and forward-planning is recommended for people considering purchasing this car. It’s a premium vehicle, which often means luxury and class, but can also mean higher than average repair costs.

The X5 reports average repair costs of £1,847.70, however, this is understandable as it is a larger car with various more complex and expensive systems that could require repairs. It’s also worth noting the BMW X5 reported the lowest average repair cost on our Lower Reliability list, meaning whilst repair costs can be high, on average they are lower than other premium vehicles on the list.

Suspension-related repair requests appear most regularly (as they do with the BMW X7 and BMW 7-Series), which is consistent with a large luxury SUV designed around ride comfort [3]. Adaptive suspension systems, air suspension components and complex chassis technology can all contribute to higher repair costs as the vehicle ages. 

Large executive SUVs like the X5 combine multiple advanced systems, including:

Adaptive or air suspension (on certain variants)
Complex automatic gearboxes
High-output petrol and diesel engines
Advanced infotainment and driver-assistance systems

As a result:

Suspension and electrical-related repair requests can sometimes appear more regularly
Average repair costs are higher due to specialist labour and premium components

An Overall Reliability Score of 23.6/100 reflects the X5’s performance capability and engineering sophistication rather flaws in design or lack of durability. Larger vehicles with more moving parts and complex systems naturally carry greater financial exposure as they age.

A full-service history and evidence of proactive maintenance are particularly important when buying used.

Why reliability can vary between BMW X5 models:

While the BMW X5 can be associated with higher risk ownership, reliability is never guaranteed.

Factors that can influence repair likelihood include:

Servicing and maintenance history: Having your car serviced and maintained at the manufacturer’s specified intervals can reduce repair likelihood.

Mileage and driving style: Accelerate gently, avoid harsh braking and try to maintain steady speeds.

Urban use versus longer motorway journeys: Frequent, short trips (where the car’s engine never reaches full operating temperature) can increase stress on starter motors, reduce battery life and cause increased wear on various engine components [4].

Previous owners and care standards: Insist on a full-service history and try to investigate previous owners’ care for the car.

Hybrid vs petrol powertrains: Hybrid X5 models, for example, introduce additional electrical components [5] that may alter long-term repair patterns, while higher-mileage examples may naturally face wear-related repairs sooner.

Our reliability data is best used as a guideline, not a guarantee. Two identical BMW X5 models can perform very differently depending on how they’ve been looked after.

What people love about the BMW X5:

People love the BMW X5 for its sporty performance, premium comfort and versatile practicality. With powerful engines, sharp handling and a high-quality interior, it delivers smooth everyday driving and long-distance comfort. Tech-rich, spacious and capable, the X5 blends luxury SUV refinement with dynamic driving appeal.

Owners are typically drawn to the X5 for its balance of performance and practicality.

Commonly praised strengths include:

Strong engine performance and towing capability
Confident, composed motorway driving
High-quality interior materials and finish
Practical cabin space for families

For many drivers, the X5 delivers executive comfort alongside everyday usability. It delivers practicality and prestige that few vehicles match.

BMW X5 safety:

The BMW X5 received a five-star Euro NCAP safety rating (2018) with standard equipment [6]. This rating has since expired but still provides useful context for structural safety performance at the time of assessment.

Higher-specification models often include adaptive cruise control, lane assistance and advanced braking technologies, supporting long-distance confidence.

How much does a used BMW X5 cost?

Used prices vary significantly depending on generation, engine and specification, but typical UK examples include:

Vehicle age	Typical mileage	Price range
3–5 years old	Under 50k miles	£45,000 – £70,000
5–7 years old	Under 70k miles	£28,000 – £45,000
7-9 years old	Under 90k miles	£18,000 – £30,000

Prices will vary depending on age, mileage, spec and general condition. Price ranges from Autotrader, March 2026. Prices subject to change.

Although older examples may appear attractively priced compared with their original list cost, buyers should consider the potential cost of maintaining a large premium SUV.

Many UK drivers experience unexpected repair costs each year. In 2025, the RAC reported that two-thirds (65%) of drivers have had to fork out for unexpected car repair costs in the last year [7] – up from 59% last year.

With the average X5 repair cost coming in at £1,848, it’s important to be confident your budget can accommodate potential repair work over a longer time.

Is the BMW X5 a sensible used buy?

The BMW X5 may suit you if:

You prioritise performance, comfort and interior quality
You understand the running costs associated with large luxury SUVs
You choose carefully with full service history and inspection
You budget realistically for maintenance and potential repairs

Things you may wish to consider:

Repair costs can be significantly higher than mainstream SUVs
Complex suspension and drivetrain systems increase long-term exposure

No vehicle is inherently good or bad – ownership experience depends on maintenance, mileage, usage patterns and previous care.

Warranty considerations:

Given the BMW X5’s complexity and repair cost profile, some owners consider a car warranty to help manage the financial impact of unexpected repairs once manufacturer warranty has expired.

Warrantywise plans start from just £40 per month for the X5, helping drivers spread the cost and budget for unexpected repair bills. (Prices may vary depending on your specific warranty plan.)

If explored, it is sensible to:

Read the warranty plan carefully to understand what is and isn’t included
Treat it as a budgeting tool rather than a guarantee
Weigh the cost against your mileage, usage and risk tolerance

If you’re considering a used BMW X5, you may wish to consider a warranty for your car as part of your ownership planning.
