The E39 M5 with its S62 V8 is an incredible performance sedan, but it demands serious preventive maintenance and deep pockets. The engine and manual transmission are robust when properly maintained, but VANOS, rod bearings, and wear items add up fast.
Rod Bearing Failure (S62 Engine)
Occasional · high severity
Typical onset: 80,000-120,000 mi
Symptoms: Metallic knocking on cold start that fades as engine warms, Metal shavings in oil during oil change, Low oil pressure warning at idle, Catastrophic engine failure if ignored
Fix: Engine-out job requiring complete disassembly. Replace all rod bearings, main bearings recommended while you're in there. 30-40 labor hours at a specialist shop. Many owners do this preventively around 80k-100k miles.
Estimated cost: $6,000-9,000
VANOS System Degradation
Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Rough/lumpy idle especially when cold, Rattling noise on startup for 2-3 seconds, Loss of power in mid-range RPMs, Check engine light with cam position codes
Fix: Replace VANOS solenoids, seals, and often the VANOS units themselves. Lines and filters should be cleaned or replaced. DIY-friendly if mechanically inclined, 8-12 hours for a shop. Use OEM or quality rebuilt units only.
Estimated cost: $2,500-4,500
Timing Chain Guides and Tensioners
Common · high severity
Typical onset: 100,000-150,000 mi
Symptoms: Rattling from front of engine on cold start, Plastic bits in oil pan during changes, Chain slap noise under acceleration, Catastrophic valve-to-piston contact if chain jumps
Fix: Engine-out recommended for proper access. Replace all guides, tensioners, rails, and chain. Often bundled with rod bearing job to save labor. 25-35 hours labor depending on shop efficiency.
Estimated cost: $5,000-8,000
Transmission Output Shaft Bearing (Manual)
Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Grinding or whirring noise in neutral with clutch out, Noise disappears when clutch pedal is pressed, Gets louder with engine RPM, No shifting difficulty initially
Fix: Transmission must be removed. Replace output shaft bearing and inspect input shaft bearing while trans is out. Resurface flywheel and replace clutch if near end of life. 12-16 hours labor.
Estimated cost: $2,000-3,500
Cooling System Failures
Common · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Coolant loss with no visible leaks, Overheating in traffic or spirited driving, Coolant smell from vents, White smoke from exhaust (head gasket)
Fix: Radiator, expansion tank, water pump, and all hoses should be replaced as a system around 80k miles. Thermostat and auxiliary water pump also common culprits. Head gaskets less common but catastrophic. Budget 6-10 hours for complete refresh.
Estimated cost: $1,800-3,000
Subframe and Differential Mount Cracking
Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Clunking from rear during hard acceleration or deceleration, Wheel hop under heavy throttle, Visible cracks in subframe mounting points, Misalignment that won't stay fixed
Fix: Rear subframe reinforcement plates should be installed preventively. If already cracked, requires welding repair or subframe replacement. Differential mounts separate issue but often done together. 8-14 hours depending on damage.
Estimated cost: $1,500-3,500
Owner tips
Change oil every 5,000 miles with quality full synthetic — this engine is unforgiving of neglect
Do rod bearings preventively at 80k-100k miles if no service history exists; it's cheaper than a new engine
Replace cooling system as a complete package around 80k miles — individual repairs waste labor
Find a specialist who knows S62 engines; general BMW shops often misdiagnose VANOS and bearing issues
Budget $3,000-5,000/year in maintenance and repairs if you plan to drive it hard
Buy only with full service records and a pre-purchase inspection by an M5 specialist, then budget heavily for maintenance — this is a $15k car with $60k car running costs.

VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH 18-INCH TIRES. (18-INCH TIRES ARE STANDARD EQUIPMENT ON THE M5 AND OPTIONAL EQUIPMENT ON THE 7-SERIES MODELS). THE MACHINE USED TO MOUNT AND INFLATE THE TIRES ON THE WHEELS AT THE ASSEMBLY PLANT MAY HAVE DAMAGED THE SIDEWALL OF ONE OR MORE TIRES. THE DAMAGED AREA COULD WEAKEN TO THE POINT WHERE A SUDDEN LOSS OF AIR FROM THE TIRE COULD OCCUR.
Consequence: HANDLING AND CONTROL WOULD BE DRASTICALLY AFFECTED INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE TIRES AND IF DAMAGE FROM THE MOUNTING MACHINE IS FOUND, THE TIRE WILL BE REPLACED. OWNER NOTIFICATION BEGAN MARCH 10, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT BMW AT 1-800-831-1117.
EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH · 00V048000

VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE BRAKE LAMPS IN THESE VEHICLES ARE CONTROLLED BY A SWITCH ACTIVATED BY THE MOVEMENT OF THE BRAKE PEDAL. THIS SWITCH COULD FAIL INTERNALLY, CAUSING IT TO REMAIN EITHER IN THE "BRAKE LAMPS OFF" POSITION OR IN THE "BRAKE LAMPS ON" POSITION.
Consequence: IF THIS HAPPENS, THE BRAKE LAMPS EITHER WILL NOT OPERATE OR WILL BE CONTINUOUSLY ILLUMINATED, REGARDLESS OF BRAKE PEDAL POSITION.
Remedy: DEALERS WILL INSPECT AND, IF NECESSARY, REPLACE THE EXISTING BRAKE LAMP SWITCH WITH AN IMPROVED SWITCH.
