The 2017 X6 (F16 chassis) is plagued by catastrophic engine failures on the N63TU V8, while the B58 inline-six is vastly more reliable. The V8's rod bearing and timing chain issues can destroy engines between 60k-100k miles, making pre-purchase inspection critical.
N63TU V8 Rod Bearing Failure (Spun Bearings)
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: metallic knocking from engine bay at idle, sudden loss of oil pressure, complete engine seizure if driven after noise starts, metal shavings in oil during changes
Fix: Requires complete engine-out teardown to replace all rod bearings, main bearings, and associated hardware. 30-40 labor hours depending on collateral damage. Many shops recommend short-block replacement instead due to hidden damage. Preventive bearing replacement at 60k extends life but doesn't eliminate risk.
Symptoms: rattling on cold starts that fades after 10-15 seconds, check engine light with timing correlation codes (P0016/P0017), rough idle and misfires, catastrophic valve damage if chain jumps or breaks
Fix: Engine-out job on the hot-V turbo setup—requires removing turbos, exhaust manifolds, and valley components to access chains. Guides, tensioners, and both chains must be replaced. 25-35 labor hours. Often discovered too late after internal damage occurs.
Estimated cost: $7,000-12,000
N63TU Piston Ring Failure and Oil Consumption
Common · high severity
Typical onset: 50,000-90,000 mi
Symptoms: burning one quart of oil every 800-1500 miles, blue smoke on startup or acceleration, carbon buildup on intake valves causing rough running, fouled spark plugs
Fix: Rings fail due to heat and inadequate oiling in the hot-V design. Repair requires full engine disassembly—pistons out, ring replacement, cylinder honing. Often combined with rod bearing replacement since engine is already apart. 35-45 labor hours. Many opt for remanufactured engine instead.
Estimated cost: $12,000-20,000
ZF 8HP Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 50,000-80,000 mi
Symptoms: transmission fluid spots under vehicle, low fluid warning on iDrive, harsh shifting when fluid level drops, transmission overheating in severe cases
Fix: Plastic quick-connect fittings and cooler lines crack from heat cycling. Lines run through crossmember area requiring subframe drop or creative access. Replace all cooler lines and fittings as assembly. 4-6 labor hours depending on access method.
Estimated cost: $800-1,500
Transfer Case Actuator Motor Failure (xDrive)
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: drivetrain malfunction warning on iDrive, vehicle stuck in front-wheel drive, grinding or whining from center of vehicle, 4WD system unavailable message
Fix: Actuator motor seizes or gear teeth strip inside the transfer case servo unit. Replacement requires exhaust removal and transfer case lowering for access. 3-5 labor hours. Entire actuator assembly must be replaced; internal gears cannot be serviced separately.
Estimated cost: $1,200-2,200
High-Pressure Fuel Pump Failure (N63TU)
Occasional · medium severity
Typical onset: 70,000-120,000 mi
Symptoms: long crank before starting, limp mode with reduced power, fuel pressure codes (P0087 low pressure), rough idle and hesitation under load
Fix: Pump located in the valley between cylinder banks on the hot-V engine. Requires intake manifold removal and valley pan access. Replace pump, filter, and check injectors for contamination. 6-8 labor hours. Contaminated fuel accelerates failure.
Estimated cost: $1,800-3,000
Owner tips
If buying a V8 model, get a pre-purchase inspection with borescope cylinder check and oil analysis—walk away from ANY metal in the oil
The B58 3.0L inline-six is dramatically more reliable; strongly consider that engine over the N63TU V8
Change transmission fluid every 40k miles despite BMW claiming 'lifetime'—prevents valve body and mechatronic failures
Monitor oil consumption religiously on V8 models—more than 1qt per 2000mi indicates ring problems that will only worsen
Extended warranty is near-mandatory on V8 models given $10k-20k engine failure risk
Buy the B58 inline-six model only—the N63TU V8 is a financial time bomb that destroys engines with alarming regularity, even with meticulous maintenance.

BMW of North America, LLC. (BMW) is recalling certain 2015-2019 X6 sDrive35i, X6 xDrive35i, X6 xDrive50i, and X6M vehicles equipped with rear seat lower anchor bars used in securing child restraint seats. The lower anchor bars may become damaged over time when used with an ISOFIX-type, rigid-style connector, child restraint system.
Consequence: Damaged lower anchor bars may increase the child's risk of injury in the event of a crash.
Remedy: BMW will notify owners, and dealers will weld a reinforcing bracket to the lower anchor bars and the vehicle body, free of charge. Owner notification began January 17, 2020. Owners may contact BMW customer service at 1-800-525-7417.

BMW North America, LLC (BMW) is recalling certain 2017 BMW X5 M and BMW X6 M vehicles. The vehicles are equipped with 21-inch tires, however the Tire Information Label states that the vehicles are equipped with 20-inch tires. As such, these vehicles fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) number 110, "Tire Selection and Rims."
Consequence: The incorrect tire size on the label does not comply with FMVSS number 110.
Remedy: BMW has notified the affected owners and is providing them with a corrected tire information placard, free of charge. The recall began June 15, 2017. Owners may contact BMW customer service at 1-800-525-7417.
