How reliable is the BMW 3 Series? What the evidence shows

We don't give the 3 Series a reliability score — no public source measures breakdowns, warranty claims or repair costs across every model, so a single number would be invented. This is what we can source for cars built from 2012.

By generation

Newer generations have had less time on the road for problems to show, so a short list is not a clean bill of health.

Where these come from: our research is built from manufacturer statements and motoring publications, most of them British. A warranty extension or goodwill scheme described here may have been offered in another country only — ask a dealer here whether it applies to your car.

3 Series (Mk7, G20/G21) (2018 on)

Acknowledged by the manufacturer

Problems the maker has admitted — through an extended warranty, a compensation scheme, a service action or a statement.

None that we hold for this model.

Reported by owners and the motoring press

Problems at least two independent publishers report on this model, that the maker has not acknowledged. They describe the model, not this car — many cars never have them.

3 Series Gran Turismo (F34) (2012–2019)

Acknowledged by the manufacturer

Problems the maker has admitted — through an extended warranty, a compensation scheme, a service action or a statement.

None that we hold for this model.

Reported by owners and the motoring press

Problems at least two independent publishers report on this model, that the maker has not acknowledged. They describe the model, not this car — many cars never have them.

3 Series (Mk6, F30/F31) (2011–2019)

Acknowledged by the manufacturer

Problems the maker has admitted — through an extended warranty, a compensation scheme, a service action or a statement.

None that we hold for this model.

Reported by owners and the motoring press

Problems at least two independent publishers report on this model, that the maker has not acknowledged. They describe the model, not this car — many cars never have them.

These describe the model, not one car. Plenty of cars never have the problems their model is known for. Every problem links to its sources; a reported problem needs two independent publishers before we list it.

Recalls aren't listed here. A franchised dealer can tell you from the VIN whether a recall is open on a particular car.

Common questions

Is the BMW 3 Series reliable?

We don't score reliability: no public source records breakdowns, warranty claims or repair costs across every model, so a single rating would be guesswork. What we hold for BMW 3 Series cars built from 2012: 0 problems BMW has acknowledged, through a warranty extension, goodwill scheme or service action, and 12 reported by at least two independent publishers — listed above by generation, each with its sources. Which matter depends on the generation and engine, and on whether the work has been done, which a service history check shows.

What are the most common BMW 3 Series problems?

For cars built from 2012, the problems at least two independent publishers report include: Diesel particulate filter can block on short-trip use; Rocker cover gasket oil leaks; Infotainment, phone and software-update glitches; Sunroof can rattle or creak; 3.0 turbo petrol (N55): oil filter housing and rocker cover leaks. Which apply depends on the generation and engine — they are listed generation by generation above, each with its sources.

Has BMW acknowledged problems with the 3 Series?

We haven't found a warranty extension, goodwill scheme or service action in which BMW acknowledged a problem on this model. The reported problems above come from the motoring press.

Does every 3 Series have these problems?

No. These describe the model; many cars never have them, and a well-maintained car is less likely to. Whether a known problem was fixed is what a service history shows: our check returns the manufacturer's dealer records by VIN, and there's no charge if we find nothing.

Has this car had the work done?

A known problem matters far less on a car whose dealer records show it was fixed. A service history check returns the manufacturer's own dealership records for a specific car, found by its VIN — what was done, when and at what mileage — and there's no charge if we find nothing.
