Essential maintenance

Critical for safety and preventing major damage

Engine Oil Service (CBS)

Every 10,000 mi

Replace BMW Longlife-04 (LL-04) full-synthetic oil and filter every 10,000 miles or annually — whichever the CBS system signals first. M-series engines may require shorter intervals; check the vehicle-specific iDrive screen.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Brake Fluid Service (CBS)

Every 24,000 mi

Replace DOT 4 LV brake fluid every 2 years regardless of mileage. CBS triggers based on time, not miles, due to moisture absorption.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Vehicle Check / Inspection (CBS)

Every 30,000 mi

Multi-point inspection covering brakes, suspension, steering, exhaust, fluids, lighting, and underbody. CBS signals every 30,000 miles or 2 years.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free with any paid service. A flashlight and 10 minutes covers the basics yourself.

Engine Air Filter

Every 40,000 mi

Replace engine air filter every 40,000 miles. Higher-performance N55, B58, and S58 engines should be inspected at every oil service.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Spark Plugs

Every 60,000 mi

B48 (2.0L turbo) and B58 (3.0L turbo) require new spark plugs every 60,000 miles. N20/N55 engines often spec 45,000 miles. M-series typically 30,000 miles.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Automatic Transmission Fluid (ZF 8HP)

Every 60,000 mi

BMW labels the ZF 8HP automatic as 'lifetime fill,' but independent transmission specialists strongly recommend replacement every 60,000 miles. Use BMW-spec ZF Lifeguard 8 — no substitutes.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Rear Differential Fluid

Every 60,000 mi

RWD and xDrive AWD: replace rear diff fluid every 60,000 miles, sooner with M-Sport or active differential. M-cars require BMW SAF-XO synthetic.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.

xDrive Transfer Case Fluid

Every 60,000 mi

BMW xDrive AWD: replace transfer case fluid every 60,000 miles. Skipping this causes the most common xDrive failure — actuator stuck in 100/0 split.

Estimated cost — typical U.S. ranges

Dealer

~$105–$140

Shop

~$75–$100

DIY

~$15–$40

AWD/4WD vehicles only. Easy drain-and-fill on most platforms.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Microfilter (Cabin Air Filter)

Every 30,000 mi

Replace the activated-carbon microfilter every 30,000 miles. Most BMWs have a single combined cabin/charcoal filter behind the engine bay firewall.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

Engine Coolant (G48 / HT-12)

On condition / lifetime

BMW labels coolant as lifetime fill on most modern vehicles. Independent BMW specialists recommend replacement every 4-5 years to prevent water-pump and thermostat housing degradation.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Fatal crash history & reported problems

Occupant deaths in fatal crashes (FARS)

How the 159 occupant deaths break down

106

driver deaths

52

passenger deaths

1

not recorded by seat

159

occupant deaths

Crash years covered: 1990–2024 This model year first appears in 1999 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number

FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.

Why we show driver deaths too

Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.

Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.

IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.

Owner-reported problem signals

Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
