LANE DEPARTURE: LANE KEEP: STEERING ASSIST

Campaign #18V374000 · Jun 6, 2018

Issue: BMW of North America, LLC (BMW) is recalling certain 2018-2019 BMW X3 xDrive30i, X3 sDrive30i, and X3 M40i vehicles equipped with the "Active Lane Keeping Assistant" option. The steering wheel may be incompatible with the lane keeping assistant function and may not detect if the driver's hands are off the wheel.

Risk: If the sensors do not properly detect the driver's hands are off the wheel, the driver may not be alerted by one or more warning signals, increasing the risk of a crash.

Fix: BMW will notify owners, and dealers will inspect the steering wheel, replacing it if necessary, free of charge. The recall began on July 19, 2018. Owners may contact BMW customer service at 1-800-525-7417.

Risk: In the event of a crash necessitating air bag deployment, the air bag could damage the instrument panel and cause small pieces of the panel to strike the driver or other occupants, increasing the risk of injury.

Fix: BMW will notify owners, and dealers will replace the instrument panel casing, free of charge. The recall began May 15, 2020. Owners may contact BMW customer service at 1-800-525-7417.

Fix: BMW will notify owners, and dealers will replace the front seats, free of charge. The recall began September 27, 2019. Owners may contact BMW customer service 1-800-525-7417.

Issue: BMW of North America, LLC (BMW) is recalling certain 2018 BMW X3 xDrive30i and X3 M40i vehicles. The rear turn signals on the outboard side panel will illuminate red, while the inboard turn signals simultaneously illuminate amber. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: Turn signals that flash multiple colors may confuse other drivers, increasing the risk of a crash.

Fix: BMW will notify owners, and dealers will inspect the rear turn signal lights, and replace if necessary, free of charge. The recall began August 20, 2018. Owners may contact BMW customer service at 1-800-525-7417.

The back-up camera and display settings can be adjusted such that the rear view image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rearview Mirrors."

Risk: The lack of an image in the back-up camera display increases the risk of a crash.

Fix: BMW will notify owners, and dealers will update the back-up camera software, free of charge. The recall began November 8, 2019. Owners may contact BMW customer service at 1-800-525-7417 or Rolls-Royce at 1-877-877-3735. Toyota owners may contact Toyota customer service at 1-888-270-9371.

The front passenger seat occupant classification system may have been improperly assembled, which could result in the misclassification of the seat as unoccupied, and deactivate the front air bag.

Risk: A deactivated front air bag will not deploy in the event of a crash, increasing the risk of injury.

These vehicles may have an error in the software for the instrument panel, causing the display to not properly illuminate. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 101, "Control and Displays."

Risk: If the display does not illuminate during start up or does not illuminate various control and warning symbols while driving, it can increase the risk of a crash.

Recall data refreshed Jul 19, 2026.

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.
