BMW SIB 11 03 17 identifies F26 X4 xDrive28i N20 vehicles produced from March 2014 through February 2015. A lower-engine whine that increases with engine speed can be associated with timing-chain or oil-pump-drive-chain wear; the bulletin does not declare every X4 or every N20 defective.

This issue also affects: BMW 1 Series, BMW 2 Series, BMW 3 Series

Common Symptoms

  • Whining from the lower engine area
  • Noise frequency increases with engine speed

How to Fix

Confirm the exact xDrive28i variant, N20 engine, production date and VIN eligibility, then have a BMW-qualified technician reproduce the noise and follow current BMW diagnosis before replacing anything. The historical seven-year/70,000-mile coverage was a limited warranty extension, not a recall, and is not a current coverage promise.

The N20 2.0L turbocharged engine in 2015-2016 X4 xDrive28i models suffers from premature timing chain stretch and guide failure, typically between 40,000-80,000 miles. The single-row timing chain design is inadequate for the engine's power output. Chain stretch causes timing to jump, leading to rough running, poor performance, and potential catastrophic engine damage if the chain breaks. BMW issued a class action settlement covering 8 years/100,000 miles. This is identical to the N20 issue affecting all N20-powered BMW models including X3, 3/4 Series, and X1.

This issue also affects: BMW 1 Series, BMW 2 Series, BMW 4 Series

Common Symptoms

  • Rattling noise from engine on cold start (first 5 seconds)
  • Check engine light with timing correlation codes (P0016, P0017, P0018, P0019)
  • Rough idle or misfires
  • Loss of power or hesitation on acceleration
  • Engine won't start after chain failure

How to Fix

Complete timing chain kit replacement including chain, guides, tensioner, and sprockets. Must be performed by experienced BMW technician. Preventive replacement recommended at 60,000-80,000 miles. BMW extended warranty to 8 years/100,000 miles under class action settlement. Upgraded reinforced chain kit available from aftermarket. Labor is 10-14 hours for X4 due to AWD and tight engine bay.

BMW SIB 01 14 23 describes a crankcase pressure control valve (PCV) diaphragm that can rupture or split over time on VIN-eligible vehicles, including MY2019 G02 X4 M40i (B58M) produced January 3, 2018 to July 15, 2019. Blue/white smoke after a cold start, a high-frequency whistle at idle, cylinder 6 misfire faults or limp mode may occur, but those symptoms alone do not select a repair. BMW extended the PCV limited warranty to 15 years/150,000 miles for eligible vehicles.

This issue also affects: BMW Z4, BMW 2 Series, BMW 4 Series

Common Symptoms

  • Blue/white exhaust smoke after a cold start, sometimes while driving
  • High-frequency whistling from under the engine acoustic cover at idle
  • Check engine light with cylinder 6 misfire faults
  • Engine shudder or reduced power (limp mode)

How to Fix

Maintain the correct oil level and specification using the exact vehicle's instructions; do not run low, overfill, or withhold needed oil merely because smoke appears. Seek diagnosis for unexplained loss. For the eligible MY2019 M40i, verify the VIN-specific notice and applicable market/coverage, then perform the specified crankcase-pressure diagnosis: normal or low vacuum does not qualify for this service solution; excessive vacuum directs the PCV repair-kit branch. Do not automatically replace the cover or turbo, or extend that branch to S58. This is a conditional limited-warranty bulletin, not a recall or blanket free repair.

BMW X4 models with N20, N55, B46, B48, and B58 engines commonly develop oil leaks from valve cover gaskets and oil filter housing gaskets. The plastic valve cover warps from heat cycles, causing gasket failure. The oil filter housing (integrated into engine block) also develops leaks. These are wear items that typically fail between 60,000-100,000 miles. Oil leaks onto hot exhaust components, causing burning oil smell but rarely major issues if addressed promptly.

This issue also affects: BMW 6 Series, BMW M6, BMW X3 M

Common Symptoms

  • Burning oil smell, especially after driving
  • Visible oil on valve cover or around oil filter housing
  • Low oil level warning (slow leak)
  • Oil residue on engine bay components
  • Smoke from engine bay when hot

How to Fix

Replace valve cover gasket and/or oil filter housing gasket. Valve cover replacement is 3-4 hours labor on X4. Oil filter housing gasket is 1-2 hours. Both are routine maintenance items on BMW turbo engines. Use OEM gaskets for best longevity. Clean oil residue from engine bay after repair. Monitor oil level regularly to catch leaks early.

Recall 20V355 includes certain 2020 X4 M vehicles. BMW SIB 32 01 20 lists the F98 production window as March 11 to April 10, 2019; the broader October 2018–July 2019 dates cover other models in the campaign. Affected steering-gear tie rods can become damaged and break, increasing crash risk. Confirm the individual VIN; standard X4 xDrive30i and M40i are not the X4 population listed in this campaign.

This issue also affects: BMW X3 M, BMW X4 M, BMW M3

Common Symptoms

  • Often no warning: the owner may not be able to tell the tie rod is affected
  • Tie rod may break, affecting vehicle handling and control

How to Fix

Check the VIN for recall 20V355. BMW replaces both steering-gear tie rods and checks/adjusts alignment on affected vehicles at no charge. Do not use the absence of noise, tyre wear or detectable play to conclude that an open recall can be ignored. Steering instability or abnormal play requires prompt professional assessment and recovery if unsafe to drive.

Recall 23V770 includes certain 2024 X4 vehicles. BMW SIB 32 04 23 describes an internal steering-gear component that may not have been properly tightened during assembly, potentially causing excessive noise, especially when parking or making tight turns; NHTSA notes a loose steering gear can cause loss of vehicle control. A VIN check is needed; noise alone cannot confirm this defect.

Common Symptoms

  • Unusual noise from the steering gear, especially when parking or in tight turns

How to Fix

Check the VIN for recall 23V770. For affected vehicles, BMW replaces the complete steering gear and initializes the electromechanical steering using the prescribed diagnostic procedure. Do not attempt to cure the recalled assembly by retightening accessible bolts. Have abnormal steering noise, vibration or control problems professionally assessed; arrange recovery if the vehicle is unsafe to drive.

BMW recalled more than 720,000 vehicles in August 2024 because small drops of liquid from the positive crankcase ventilation system can drip onto and penetrate the electrical plug connector of the electric coolant pump. Over time this can lead to a short circuit and, in rare cases, a thermal event. The 2015-2018 X4 xDrive28i (F26) is named in the campaign. This is distinct from an ordinary worn-out pump: BMW states the electric coolant pump itself is not recalled, and the remedy centres on the connector and a retrofitted protective splash cap. BMW reported roughly 18 customer complaints and no crashes or injuries at the time of the recall.

This issue also affects: BMW 1 Series, BMW 2 Series, BMW 3 Series

How to Fix

Check the VIN for recall 24V608 / BMW SIB 11 07 24. For an affected vehicle, the dealer inspects both sides of the coolant-pump electrical connection, repairs or replaces components as the recall procedure requires, and retrofits the protective splash cap. Standalone worn or leaking pumps are not the recall defect. Burning, smoke or overheating requires stopping safely and arranging professional assistance; a clean-looking connector or failed pump command is not enough to identify the fault.

On the European-market X4 20d, 30d and 35d, coolant (glycol) can leak from the exhaust gas recirculation cooler. Combined with soot deposits and the high temperatures inside the EGR system, the leaking glycol can produce burning soot deposits that can melt the intake manifold and in the worst case start a fire. BMW's UK recall named X4 (20d, 30d, 35d) vehicles manufactured between December 2013 and June 2017. US X4s were never sold with these diesels, so this is a European and UK issue.

Common Symptoms

  • Unexplained coolant loss
  • Burning smell from the engine bay
  • Engine warning light

How to Fix

Free manufacturer recall remedy: owners of affected cars are invited to book in at a BMW retailer for the recall work, carried out free of charge. Owners of UK cars can check status through the DVSA recall check or a BMW dealer using the VIN. Have repeated unexplained coolant loss on a diesel X4 diagnosed and the recall status confirmed.

Recall 19V678 covers 368 US-market X3 and X4 vehicles, including certain 2020 X4 xDrive30i and M40i vehicles. A manufacturing heat-treatment problem can weaken a front swivel bearing and allow it to break, potentially causing loss of control. BMW instructed potentially affected owners not to drive their vehicles. The reviewed recall material does not establish clunking, steering pull or tire wear as reliable advance indicators.

Common Symptoms

  • Potential loss of vehicle control if a swivel bearing fails; do not wait for symptoms to arrange recall service

How to Fix

Do not drive a potentially affected vehicle before the recall remedy is completed. Contact BMW to verify the VIN and arrange transport and the required swivel-bearing replacement at no charge. The reviewed bulletin reproduction contains inconsistent left-versus-both-side instructions; the dealer must use the applicable current VIN-specific BMW campaign procedure. Do not select the replacement side from generic symptoms or assume lack of noise means the vehicle is safe.

The transmission supplier discovered that at least one mechatronics unit left the line without all of the bolts required to assemble it. The missing fasteners can cause an internal leak inside the transmission, and in rare cases this could result in a rollaway condition. NHTSA campaign 22V-070 is tiny - four vehicles in total - but it names the 2022 X4 xDrive30i specifically (one vehicle built December 14, 2021) alongside the 330i, 530i and X3 xDrive30i. Owner notification was planned for April 2022.

Common Symptoms

  • Vehicle may roll away after being placed in Park (rare)

How to Fix

Free remedy under NHTSA campaign 22V-070: replacement of the transmission mechatronics unit at an authorized BMW dealer. Confirm by VIN with BMW whether the campaign applies and has been completed; when buying a used 2022 X4, ask BMW for the VIN-specific campaign completion record, since NHTSA's VIN search does not display completed recalls.

The G02 X4's cooling system uses plastic hoses, connectors and quick-disconnect fittings, and X4 reliability guides report slow coolant leaks at plastic parts such as the expansion tank and thermostat housing that can escalate if ignored. Separately, BMW service bulletin SIB 17 03 20 covers coolant leaks from quick-disconnect coolant lines whose O-rings do not seal at or below -15C / 5F, on the G01 X3, G02 X4, G05 X5 and G07 X7 built up to March 31, 2019. This is a platform-wide B46/B48/B58 cooling system, shared with the X3 and 3 Series.

This issue also affects: BMW 2 Series, BMW Z4, MINI Countryman

Common Symptoms

  • Low coolant warning that keeps returning
  • Sweet coolant smell after driving
  • Crusty residue at hose fittings with no visible drip
  • Temperature gauge climbing
  • Heater blowing cool at idle

How to Fix

Locate the coolant leak using the BMW procedure for the exact engine and cooling circuit. SI B17 03 20 covers listed vehicles built through March 31, 2019 with a confirmed leak when ambient temperature is at or below −15°C (5°F). For that condition, replace all hoses specified in the applicable vehicle/engine attachment if any listed quick disconnect shows coolant loss. Do not extend that grouped replacement rule to every adjacent connector or later X4 solely because it is plastic or aged. Confirm correct parts and coolant by VIN, and do not continue driving with overheating or significant coolant loss.

The rear differential mounting bushings on the X4 degrade over time, causing clunking and vibration from the rear of the vehicle. The rubber bushings crack and collapse, allowing excessive differential movement. Common in models driven aggressively or on rough roads.

Common Symptoms

  • Clunking noise from rear when accelerating or decelerating
  • Vibration felt through floor and seats
  • Driveline shudder during low-speed maneuvers
  • Thud when shifting from Drive to Reverse
  • Rear end feels loose or disconnected
  • Noise worsens over bumps

How to Fix

Replace rear differential mount bushings. Both front and rear differential bushings should be inspected and replaced as a set. Upgraded aftermarket bushings with stiffer rubber or polyurethane are available for longer service life.

BMW xDrive (AWD) X4 models use an electronically-controlled transfer case that commonly experiences actuator motor failures between 60,000-100,000 miles. The transfer case actuator motor and internal clutch pack wear out from normal use. Symptoms include grinding noises, AWD malfunction warnings, and the vehicle stuck in FWD mode. The actuator motor is a common failure point and can be replaced separately, but complete transfer case failure requires full replacement. This affects all X4 generations (F26 and G02) with xDrive.

Common Symptoms

  • Grinding or whining noise from under vehicle
  • AWD malfunction warning on dashboard
  • Transfer case failsafe program message
  • Vehicle stuck in front-wheel drive only
  • Vibration during acceleration
  • Fluid leak from transfer case area

How to Fix

Diagnose specific failure. Transfer case actuator motor replacement ($800-1,200) is most common. Complete transfer case replacement required for internal failures ($2,500-4,000). Regular transfer case fluid changes every 50,000 miles may extend life. Some owners install aftermarket upgraded actuator motors. Common wear item on high-mileage xDrive BMW models.

The lower anchor bars used to attach child restraint systems can be damaged over the life of the vehicle when rigid ISOFIX-style connectors are repeatedly used on them. A damaged anchor bar may not hold the child seat as designed in a crash. NHTSA campaign 16V-333 covers roughly 188,670 US vehicles; BMW's bulletin lists F26 X4 vehicles produced from April 2014 through April 15, 2016 (model years 2015-2016). BMW notes the rigid-style connector is mainly used in Europe and that the condition is unlikely with LATCH-type flexible connectors.

Common Symptoms

  • Child seat rigid connector does not latch securely
  • Visible deformation of the lower anchor bar
  • Child seat moves excessively when checked

How to Fix

For VINs covered by 16V333, BMW arranges a free reinforcing-bracket welding repair. The January 2017 bulletin identifies X4 production from April 2014 through April 15, 2016; confirm individual eligibility with BMW. If a lower anchor bar is suspected loose, secure the child restraint using the vehicle safety belt according to both manuals, not the suspect anchors. Arrange the recall repair promptly.
