SERVICE BRAKES, HYDRAULIC:CRITICAL FASTENERS

Campaign #21V089000 · Feb 18, 2021

Issue: BMW of North America, LLC (BMW) is recalling certain 2021 X5 sDrive40i and X5 xDrive40i vehicles. The right front brake disc may have been assembled with incorrect fasteners, which over time, could result in the front brake disc becoming loose.

Risk: A loose brake disc could affect vehicle handling and control, and increase the risk of a crash.

Fix: BMW will notify owners, and dealers will inspect the right front brake disc and replace it if necessary, along with the unaffected left side brake disc, free of charge. There are no owner vehicles affected; therefore, owner notification is not necessary and, as such, a planned owner notification date is not entered into the recall schedule. Owners may contact BMW's customer service at 1-800-525-7417.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY

When shifting into Reverse, a small portion of the rearview image may be obscured, or the screen may not illuminate. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."

Risk: If the driver relies on only the rearview camera image, the missing or reduced rearview image view can increase the risk of a crash or injury.

We display NHTSA's record with attribution; we don't editorialize on what these complaints mean for any specific vehicle.

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.

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)
