How Long Do BMW Series 5 Last? (Explained)

The BMW 5 Series combines comfort, power, and high-tech features in a customizable sedan that boasts luxury and radiates success. The 5 Series carves corners during road tests and turns heads when it’s standing still.

However, this show of power comes at a hefty price. Since the BMW 5 Series costs more than many or its midsize luxury rivals, the BMW’s longevity will have to tip the scales in its favor.

So, how long does a BMW 5 Series last?

With proper care and maintenance, a BMW 5 Series should last 150,000 to 200,000 miles. If you were to drive the average of 13,500 miles a year, a new 5 Series should last between 10 to 15 years. While some owners report the BMW 5 Series models lasting much longer than this, the exact model and routine maintenance will determine how long the luxury car will last.

Continue reading to find out how reliable the BMW 5 Series is, if it’s expensive to maintain, and what years you should avoid buying used.

How Many Miles Does A BMW 5 Series Last?

A BMW 5 Series should be able to last between 150,000 to 200,000 miles if taken care of properly.

Reports show that many models can last up to 370k miles, but this kind of longevity can be reached only after several costly repairs and replacements keep the car on the road.

First, buy the right 5 Series, and the right one is not a 4-cylinder.

Even a defense of the smaller engine fails to overcome the slight price difference–often around $5,000–between the 4-cylinder and the inline-six that the BMW is better known for.

While the 4-cylinder has competitive luxury and comfort, it lacks the driving thrill that makes a BMW fun.

Furthermore, the smaller engine can’t be expected to last as long as the larger V8 or inline-six.

Other than following obvious maintenance routines, overhauling the cooling system after 100k miles is key to maintaining these cars.

The BMW engines and transmissions are famous for their strength and longevity, but the specialty German parts that make the car fun to drive can be terribly expensive to replace.

Are BMW 5 Series Reliable?

The BMW 5 Series is considered a reliable midsize luxury car.

According to Consumer Reports, the 2021 BMW 5 Series scores a 3/5 in predicted reliability based on the average reliability over the previous three years. How does that compare to other cars in its class?

ModelReliability Score
Lexus ES4/5
BMW 5 Series3/5
Mercedes-Benz E-Class3/5
Audi A63/5
Hyundai Genesis G802/5
Volvo S901/5
Maserati Ghibli1/5

BMWs are known for their reliable engines and transmissions, so a 5 Series built during a dependable model year can be a reliable luxury vehicle.

Most Reliable BMW 5 Series Years

Model year 2020 is the most reliable for the BMW 5 Series.

Consumer Reports ranked the 2020 5 Series #1 for reliability among sedans based on their Predicted Reliability score (5/5).

Let’s compare the reliability of the 5 Series in recent model years.

Model YearReliability Score (Out of 5)

The most recent seventh generation BMW 5 Series (2017-Present) earns much higher reliability rankings than the sixth generation (2011-2016).

The previous generation showed some improvement as BMW worked out some problem areas, so the 2015 and 2016 models should be considered relatively reliable used cars.

When looking at older 5 Series Models, Driving ranked the 1996-2003 model years (fourth generation) as the best, noting a stronger engine and improved handling.

BMW 5 Series Years to Avoid

Avoid the 2013, 2012, and 2011 BMW 5 Series model years, and look carefully at the 2018.

Generally, the sixth generation (2011-2016) is considered the least reliable for the BMW 5 Series.

While the generation’s appearance draws most of the criticism, the 2011-2013 models’ reliability scores only 1 out of 5 from Consumer Reports.

Although the 2018 received a low Predicted Reliability score from Consumer Reports, the model year is surrounded by relatively high reliability scores by the 2017 and 2019 models within the same generation.

Furthermore, US News ranked the 2018 #1 in luxury midsize cars, so this model year may deserve a second look.

Are BMW 5 Series Expensive To Maintain?

The BMW 5 Series is highly expensive to maintain.

RepairPal gives the BMW 535i a reliability score of 2.5 out of 5, placing it 18th out of 30 in cars of its class.

While this score is better than the BMW 550i (1.5 of 5, 29th of 30), even the 535i has “poor ownership costs.”

Let’s compare the maintenance cost of the BMW 5 Series to other cars of its class.

ModelOverall Reliability (Out of 5)Average Annual Repair CostsAverage Annual Repair Shop VisitsPercentage of Annual Urgent Repairs
Lexus ES3504$4680.616%
Volvo S804$7050.479%
Hyundai Genesis3.5$5650.5814%
Mercedes-Benz E3503.5$7880.6113%
Cadillac XTS3.5$8750.3513%
Audi A63.5$9130.2812%
BMW 531i2.5$9771.016%
Average Luxury Car2.5$9760.814%

Don’t overlook hidden repair costs.

Even if we compare the 531i to the Audi and Cadillac featured here, notice that the BMW is much more likely to have shop visits each year, and those visits are more likely to require severe repairs, meaning the car will not be available for transportation during that time.

These costs should definitely be taken into consideration when buying a used BMW 5 Series, especially one that has passed the warranty, consult a local specialized shop before handing over the money.

Unless you are a serious and specialized BMW DIYer, you’re going to have to meet the BMW mechanic eventually, so establish that relationship before you make the purchase.
