The E39 M5 with its S62 V8 is a legendary sedan, but it demands respect and deep pockets. VANOS system failures and transmission issues are nearly inevitable on higher-mileage examples, turning what should be routine maintenance into major repair events.
VANOS System Failure (Variable Valve Timing)
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: rough cold starts with excessive valve clatter, poor idle quality and hunting RPMs, loss of low-end torque, Check Engine Light with cam correlation codes
Fix: Both intake and exhaust VANOS units tend to fail due to worn seals and solenoids. Requires engine timing cover removal, VANOS unit R&R, often with updated piston seals and solenoids. 8-12 hours labor depending on shop experience with S62.
Estimated cost: $2,800-4,500
Rod Bearings Wear (Catastrophic Failure Risk)
Occasional · high severity
Typical onset: 80,000-120,000 mi
Symptoms: metallic knocking at idle that increases with RPM, metal flakes in oil during changes, sudden loss of oil pressure, some fail with no warning at all
Fix: S62 rod bearings use marginal clearances and can spin without warning. Preventive replacement requires engine-out service or in-chassis with subframe drop. 20-30 hours labor. Many owners do this preemptively at 80k-100k. Failure means complete engine rebuild or replacement.
Estimated cost: $5,000-8,000
Automatic Transmission Failure (GM 5L40-E)
Common · high severity
Typical onset: 90,000-130,000 mi
Symptoms: harsh or delayed shifts, especially 2-3 and 3-4, slipping under acceleration, transmission fault codes and limp mode, whining or grinding noises from bellhousing area
Fix: The 5-speed auto was never robust enough for S62 torque. Output shaft bearing failure is common, leading to metal contamination throughout the trans. Requires full rebuild with updated bearings, clutches, and torque converter. 12-16 hours labor plus R&R time.
Estimated cost: $4,500-7,000
Timing Chain Guide Wear
Occasional · high severity
Typical onset: 100,000-150,000 mi
Symptoms: rattling noise from front of engine on cold start, plastic fragments in oil pan during changes, Check Engine Light with cam/crank correlation codes, catastrophic failure results in valve-piston contact
Fix: S62 uses plastic-backed guides that deteriorate over time. Inspection requires removing valve covers and timing covers. Full replacement includes chains, guides, tensioners, and VANOS seals while you're in there. 18-24 hours labor. This is often combined with rod bearing service.
Estimated cost: $5,500-8,500
Cooling System Component Failures
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: overheating in traffic or under load, coolant loss with no visible leaks, white smoke from exhaust on startup, expansion tank cracks, water pump bearing noise
Fix: Expansion tank, water pump, thermostat, and auxiliary electric pump all fail predictably. The S62 runs hot and plastic components don't last. Replace expansion tank every 60k regardless of appearance. Water pump is 4-5 hours labor. Do them all at once with hoses.
Estimated cost: $1,500-2,500
Rear Subframe Mounting Point Cracks
Occasional · medium severity
Typical onset: Not mileage-driven, age and use dependent
Symptoms: clunking from rear over bumps, misalignment that won't correct, visible cracks in trunk floor sheetmetal around subframe mounts, differential vibration at highway speeds
Fix: E39 chassis, especially M5 with stiffer suspension and more torque, can crack the sheetmetal where rear subframe bolts. Requires reinforcement plates welded in, subframe removal and reinstallation. 8-12 hours labor plus alignment. Catch it early or the repair gets exponentially more complex.
Estimated cost: $2,000-4,000
Throttle Body Actuator Failure
Occasional · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: intermittent limp mode with reduced power, throttle response lag or surging, Check Engine Light with throttle actuator codes, inability to rev past 3,000 RPM in some cases
Fix: Drive-by-wire throttle actuators fail internally. Replacement throttle bodies require adaptation with BMW scan tool. 2-3 hours labor. Some owners report issues after battery disconnection requiring re-adaptation.
Estimated cost: $800-1,400
Owner tips
Change oil every 5,000 miles with quality 10W-60 and send samples to Blackstone Labs to monitor bearing wear
Budget $3,000-5,000 annually for maintenance and repairs after 100k miles — this is not a normal 5-series
Find a specialist shop with S62 experience before you need one; dealer pricing is punishing
If buying used, demand proof of rod bearing replacement or budget for it immediately
Consider the 6-speed manual if possible — the automatic is the weakest link in the drivetrain
Buy one only if you have a dedicated specialist, a healthy emergency fund, and accept that it's a $15k-20k car with $50k maintenance needs — but the driving experience is worth it if you're prepared.

AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE · 17V047000
2017-01-20 · EA15001
BMW of North America, LLC (BMW) is recalling certain 2000-2002 BMW 320i, 323i, 325i, 325xi, 330i, 330xi, 323Ci, 325Ci, 330Ci, M3, 323iT, 325iT and 325xiT vehicles, 2001-2002 525i, 530i, 540i, M5, 525iT and 540iT vehicles, and 2001-2003 X5 3.0i, X5 4.4i, and X5 4.6is vehicles. These vehicles may have had a driver-side air bag module installed as replacement equipment such as after a vehicle crash necessitating replacement of the original air bag, or as a remedy part for a prior recall. These replacement modules contain an air bag inflator that may rupture due to propellant degradation occurring after long-term exposure to lower absolute humidity, temperature and temperature cycling.
Consequence: In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could rupture with metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Owners are advised not to drive their vehicles until the vehicle has been remedied. BMW will notify owners, and dealers will inspect the driver side air bag module, replacing it as necessary, free of charge. The recall began March 15, 2017. Owners may contact BMW customer service at 1-800-525-7417.
AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE · 15V318000
2015-05-28 · EA15001
BMW of North America, LLC (BMW) is recalling certain model year 2002-2005 325i, 325xi, 330i, and 330xi Sedans, and 325xi and 325i Sportswagons, 2002-2006 330Ci, 325Ci, and M3 Convertibles and 325i, 330i, and M3 Coupes, 2002-2003 M5, 540i, 525i Sedan, and 530i Sedans, and 540i and 525i Sportswagons, and 2003 X5 3.0i and 4.4i Sports Activity Vehicles. Please note that the 5-series and X5 vehicles are only included if they are equipped with the optional sports steering wheel. The affected vehicles are equipped with a dual-stage driver frontal air bag that may be susceptible to moisture intrusion which, over time, could cause the inflator to rupture.
Consequence: In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could rupture with metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Owners are advised not to drive their vehicles until the vehicle has been remedied. BMW will notify owners, and dealers will replace the front driver air bag module, free of charge. The recall began Aug 2016. Owners may contact BMW customer service at 1-800-525-7417. Note: This recall supersedes recall 14V-348 in its entirety. Additionally, vehicles that have had their driver side frontal air bag replaced previously as part of a recall remedy need to have their air bag replaced under this recall as well. Note: On December 17, 2015 BMW removed the model year 2004 X5 3.0i and 4.4i Sports Activity vehicle from this recall. Those vehicles were mistakenly identified as including the air bags that are subject to this recall.
