The 2017 X5 xDrive50i with the N63TU2 engine is a powerful luxury SUV plagued by the N63's notorious internal engine problems, particularly timing chain and bearing failures. When maintained obsessively it can be reliable, but most examples will need major engine work between 80,000-120,000 miles.
N63 Timing Chain Guide and Tensioner Failure
Common · high severity
Typical onset: 80,000-120,000 mi
Symptoms: Cold-start rattle for 2-5 seconds that disappears when warm, Check engine light with timing correlation codes (P0016, P0017, P0018, P0019), Rough idle or misfires, Metallic rattling from rear of engine
Fix: Requires engine-out service to replace all timing chains, guides, tensioners, and usually the oil pump chain while you're in there. 25-35 labor hours depending on shop efficiency. Many techs recommend doing valve stem seals simultaneously since engine is out.
Estimated cost: $8,000-12,000
Rod Bearing and Main Bearing Wear
Occasional · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Low-frequency knocking on cold start that may persist, Metallic ticking that increases with RPM, Metal shavings in oil during analysis, Sudden catastrophic failure with no warning in worst cases
Fix: Requires complete engine disassembly. Rod bearings alone are 30-40 hours, but most techs find additional damage requiring short block replacement or full rebuild. Oil starvation from hot-V turbo design is the root cause. This is a 'you're all-in' situation.
Estimated cost: $12,000-18,000
Valve Stem Seal Deterioration and Oil Consumption
Common · medium severity
Typical onset: 60,000-90,000 mi
Symptoms: Blue smoke on cold start that clears after 30 seconds, Needing to add 1-2 quarts between oil changes, Fouled spark plugs on one or more cylinders, Smell of burning oil from exhaust
Fix: Can be done with cylinder heads on the car using specialized tools (12-16 hours) or heads-off for thorough job (20-25 hours). Smart money does this when timing chains are due since both require similar access. Replace all 32 seals, not just the leakers.
Estimated cost: $3,500-6,000
Turbocharger Oil Feed Line Leaks and Turbo Failure
Occasional · high severity
Typical onset: 70,000-100,000 mi
Symptoms: Oil pooling on top of engine or dripping onto exhaust, Burning oil smell in cabin with heat on, Loss of boost pressure, High-pitched whine or grinding from turbo area, Blue smoke under acceleration
Fix: Hot-V configuration makes turbos incredibly difficult to access—engine must be lifted or partially removed. Oil feed lines crack from heat cycling. If turbos are damaged from oil starvation, you're replacing both turbos plus all lines and gaskets. 18-28 hours depending on turbo damage.
Estimated cost: $6,000-11,000
Transmission Oil Cooler Line Leaks (ZF 8HP)
Common · medium severity
Typical onset: 50,000-80,000 mi
Symptoms: Transmission fluid pooling under vehicle, Pink or red fluid on driveway, Transmission slipping or delayed engagement when fluid is low, Burnt transmission fluid smell
Fix: Cooler lines run along subframe and corrode or crack at connections. Lines themselves are inexpensive but access requires dropping the transmission crossmember. 3-5 hours for lines alone. If cooler itself is leaking, add another 2-3 hours. Always refill with ZF Lifeguard 8 fluid only.
Estimated cost: $800-1,800
High-Pressure Fuel Pump (HPFP) Failure
Occasional · high severity
Typical onset: 60,000-90,000 mi
Symptoms: Long crank time before starting, especially when hot, Limp mode with reduced power, Check engine light with fuel pressure codes (P0087, P0088), Rough running under load, No-start condition in severe cases
Fix: HPFP sits in the valley between cylinder banks—horrible access. Requires removing intake manifold and various cooling components. Pump itself is $400-700, but labor is 6-9 hours due to tight working space. Check low-pressure pump in tank first as it's easier to diagnose.
Estimated cost: $2,000-3,500
Transfer Case Actuator Motor and Chain Wear
Occasional · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: Grinding or clunking when engaging drive modes, 4WD system warning light on dash, Drivetrain vibration at highway speeds, Inability to engage AWD system
Fix: Actuator motor fails commonly (3-4 hours labor), but if chain inside transfer case is worn, you're replacing or rebuilding the entire unit (8-12 hours). Diagnosis requires removing skid plate and inspection. Fluid changes every 50k can prevent internal damage.
Estimated cost: $1,200-4,500
Owner tips
Religious 5,000-mile full-synthetic oil changes with proper BMW LL-01FE spec are non-negotiable—this engine starves itself in the hot-V design
Get oil analysis done every other change starting at 50k miles to catch bearing wear early before catastrophic failure
Budget $2,000-3,000 annually for maintenance and repairs after 60k miles, more after 80k when timing chains come due
Inspect timing chain condition with borescope through oil fill cap around 70k miles if you hear any cold-start rattle
Extended warranty is almost mandatory on these—find one that covers internal engine components with no powertrain exclusions
Only buy if you have a $15k repair fund and detailed service records showing preventive maintenance, or you're prepared to walk away from the vehicle when the engine fails—this is not a 200k-mile platform for average owners.

Consequence: An electrical short increases the risk of a fire.
Remedy: Dealers will inspect and replace the water pump and plug connector as necessary, and install a protective shield, free of charge. Owner notification letters were mailed on March 28, 2025. Owners may contact BMW customer service at 1-800-525-7417.
FUEL SYSTEM, DIESEL · 21V907000
2021-11-19
BMW of North America, LLC (BMW) is recalling certain 2013-2018 328d, 328d xDrive, 2014-2018 328d Sports Wagon, 328d xDrive Sports Wagon, 2014-2016 535d, 535d xDrive, 2015 740Ld xDrive, 2015-2017 X3 xDrive28d SAV, and 2014-2017 X5 xDrive35d SAV diesel vehicles equipped with an Exhaust Gas Recirculation (EGR) module with an integrated cooler. The EGR cooler may leak internally, causing coolant to mix with diesel engine soot, which could result in smoldering particles and a melting intake manifold.
Consequence: A melting intake manifold increases the risk of a fire.
Remedy: Dealers will replace the EGR cooler and inspect the intake manifold, replacing it as necessary, free of charge. This recall includes all vehicles previously recalled under 18V-755. Vehicles previously recalled under 18V-755 will need to have the new remedy performed for this recall. An interim owner notification letter was mailed on January 18, 2022. The remedy is expected to be available in June 2022. Owner notification letters were mailed on July 6, 2022. Owners may contact BMW customer service at 1-800-525-7417.
BMW of North America, LLC (BMW) is recalling certain 2014-2018 328d, 328d xDrive, X5 xDrive35d, 2014-2016 535d, 535d xDrive, 2015 740Ld xDrive, and 2015-2017 X3 xDrive28d vehicles. The high-pressure fuel pump may fail.
Consequence: Fuel pump failure can cause an engine stall while driving, increasing the risk of a crash.
Remedy: Dealers will replace the high-pressure fuel pump, free of charge. Owner notification letters were mailed on January 14, 2022. Owners may contact BMW customer service at 1-800-525-7417.
BMW of North America, LLC (BMW) is recalling certain 2013-2018 BMW 328d and 328d xDrive, 2014-2018 328d Sports Wagon and 328d xDrive Sports Wagon, 2014-2016 535d and 535d xDrive, 2015 740Ld xDrive, 2015-2017 X3 xDrive28d SAV and 2014-2017 X5 xDrive35d SAV vehicles equipped with an Exhaust Gas Recirculation (EGR) module with an integrated cooler. If the EGR cooler leaks internally, the coolant can mix with diesel engine soot. The high EGR temperatures may result in these particles possibly smoldering and melting the intake manifold.
Consequence: The melting intake manifold can increase the risk of a fire.
Remedy: BMW will notify owners, and dealers will inspect and replace the EGR cooler as necessary. If a leak has already occurred, the engine intake manifold will also be replaced. These repairs will be made free of charge. The recall began May 13, 2019. Owners may contact BMW customer service at 1-800-525-7417.
EQUIPMENT:OTHER:LABELS · 17V327000
2017-05-18
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.
