TL;DR

The BMW 5 Series is a popular choice, but reliability varies by model year. Models from 2010 to 2016 are generally more reliable, while those from 2005 to 2010 often face issues like electrical faults and cooling system problems. Average MOT pass rates are around 63%.

MOT Pass Rates

MOT pass rates for the BMW 5 Series reveal a mixed picture. The average pass rate is around 63%, which is below the national average for cars in the UK. Some years, particularly from 2005 to 2010, have shown lower pass rates due to various mechanical issues.

Common Failure Modes

The most frequent issues reported include electrical faults, oil leaks, and problems with the cooling system. Electrical issues often arise in models from 2005 to 2010, where wiring harness failures are common. Oil leaks are prevalent in models with the N47 engine, particularly from 2007 to 2011.

Model Years to Favour

Models produced between 2010 and 2016 generally show better reliability. These years have fewer reported issues and higher owner satisfaction ratings. The F10 generation, specifically, is often praised for its driving experience and overall build quality.

Model Years to Avoid

Be cautious with models from 2005 to 2010. These years have higher rates of MOT failures and common faults. The E60 generation is particularly noted for its electrical problems and cooling system failures, leading to expensive repairs.

Cost of Repairs

Repair costs for common issues can be significant. Fixing electrical faults typically ranges from £200 to £600, while cooling system repairs can average around £300. Regular maintenance can mitigate some of these costs, but potential buyers should be prepared for these expenses.

What people are asking

What is the most common problem with the BMW 5 Series?

The most common problem reported is electrical faults, particularly in older models. Owners have noted issues such as malfunctioning sensors and problems with the infotainment system, which can lead to costly repairs if not addressed promptly.

Is the BMW 5 Series reliable?

Yes, the BMW 5 Series is generally considered reliable, but this can vary by model year. Models from 2010 to 2016 tend to have better reliability ratings compared to earlier years, which have been associated with more frequent issues.

Which BMW 5 Series to stay away from?

Models from 2005 to 2010 are often recommended to avoid due to their higher rates of common faults, especially electrical and cooling system issues. Buyers should do thorough research on specific model years to ensure they are making a sound investment.

Is the BMW 5 Series high maintenance?

While maintenance costs can be higher than average, regular servicing can help manage these expenses. Owners have reported that keeping up with maintenance can prevent more severe issues down the line, making it more manageable in the long run.

What owners say

A common theme is that while the cars are generally reliable, the experience can heavily depend on the engine type and model year. For instance, owners of the 2018 models often report fewer problems compared to those with older versions. Many owners have shared their experiences regarding the reliability of the BMW 5 Series.

However, they also caution that neglecting regular servicing can lead to significant issues, particularly with electrical systems. In discussions, users have praised the diesel variants for their impressive torque and fuel efficiency, noting that they are typically very reliable if maintained properly.

Another point raised by owners is the perception of the BMW 5 Series as a daily driver. Some users have mentioned that while the car is comfortable and performs well, they have noticed a decline in popularity, possibly due to the increasing number of alternatives in the market.

Finally, buyers have expressed concerns about the affordability of used models. They recommend thoroughly inspecting any used vehicle and considering the full cost of ownership before making a decision. Many have pointed out that while the initial purchase price may be attractive, the potential repair costs for older models can make them less appealing.

BMW 5 Series recall record

65 recalls have been issued for the BMW 5 Series, between 1999 and 2026.

  1. Checking and re-securing the air-conditioning wiring harness

    R/2026/092

    Issued 17 March 2026

    The Safety Recall relates to the air-conditioning wiring harness located behind the dashboard. On the affected vehicles the wiring harness was fixed very close to a screw connection on the interior microfilter housing cover. The microfilter of the air conditioning system will be regularly replaced as part of the oil service. It cannot be ruled out that cables may be damaged when replacing the microfilter during a workshop visit. The filter cover has to be removed from the lower part of the instrument panel. After replacing the filter the cover has to be refitted at which point the wires may become damaged or trapped. If the wiring harness is damaged this could lead to malfunctions of the air conditioning system as well as to a short circuit. In case of a short circuit a sensor may overheat while the vehicle is in operation. As a result smoke may develop from the instrument panel and subsequently a fire cannot be ruled out.

    Remedy:On the affected vehicles the air-conditioning wiring harness will be checked repaired if necessary and re-secured in a modified fixing.

    Affects cars built Jun 2023 to Apr 2025

  2. Replace the Engine Starter Motor

    R/2026/054

    Issued 2 March 2026

    The Safety Recall relates to the engine starter motor. The fault relates to the RSW22 starter RWT (reinforced water tightness). It was found that with RWT starters an increased abrasion of the magnetic contact can cause the growth of deposits at the lowest point of the relay interior. This in turn may increase the relay contact resistance resulting in false starts or even causing short circuits and possibly a thermal reaction. In case of a short circuit the possibility of a thermal event cannot be excluded. This may happen while attempting to start the vehicle or while driving due to vibrations causing a short circuit due to moving deposits.

    Remedy:On the affected vehicles the starter motor will be replaced with a variant by another supplier with a different design. Until the repair has been completed it is recommended to not leave the vehicle running unattended after starting the engine.

    Affects cars built Oct 2020 to Apr 2022

  3. Takata Driver and/or Passenger Airbag Recall (Global VINs)

    R/2025/349

    Issued 18 December 2025

    Affected vehicles are already included in Safety Recalls within the markets they have previously resided in. The vehicles may be fitted with a driver and/or passenger airbag/s which if deployed may do so with excessive force causing sharp metal fragments to be released this may cause serious injury which could prove fatal to people in the vicinity.

    Remedy:Vehicles will have the affected airbags checked and if necessary replaced.

    Affects cars built Sept 2000 to Sept 2003

  4. Program control units (CoC documents)

    R/2026/075

    Issued 28 November 2025

    A quality check has revealed that the affected G61 vehicles software does not reflect the associated CoC documentation.

    Remedy:To ensure your vehicle is in perfect working order we would like to program the control units to adapt the vehicle's software level to the CoC documents. as soon as possible. Naturally this work will be free of charge.

    Affects cars built Nov 2024 to Jun 2025
