The 2002 BMW M5 is a beast on the road, but when it comes to reliability, it’s a mixed bag. As a car owner, you need to be aware of what you’re getting into with this high-performance sedan. The M5 is powered by a 5.0-liter V8 engine that delivers exhilarating performance, but with great power comes great responsibility—especially in terms of maintenance.
Engine Performance and Reliability
The heart of the M5 is its S62 engine, which is known for its robust power output and thrilling driving experience. However, it’s not without its quirks.
Common Issues
- Vanos system failures: The variable valve timing can be problematic, leading to rough idling and decreased performance.
- Oil leaks: The engine can develop leaks over time, particularly around the valve cover gaskets and oil filter housing.
- Cooling system: The cooling system is critical; watch for signs of overheating, as the plastic components can become brittle with age.
Transmission Durability
The M5 comes with a 6-speed manual or a 5-speed automatic transmission, both of which are generally reliable but require proper care.
Transmission Concerns
- Clutch wear: If you opt for the manual, be prepared for potential clutch replacement, especially if you’re not gentle with it.
- Automatic transmission issues: The automatic can experience hard shifting or slipping if not regularly serviced.
Suspension and Handling
The M5’s suspension is designed for performance, but that doesn’t mean it’s immune to wear and tear.
Suspension Components
- Shock absorbers: These can wear out, affecting ride quality and handling.
- Control arms and bushings: Over time, these components can deteriorate, leading to alignment issues and uneven tire wear.
Other Key Components
Don’t overlook the smaller parts that can impact your driving experience.
Electrical System
- Battery and alternator: Keep an eye on these; they can fail unexpectedly.
- Sensor failures: Various sensors, including those for the engine and transmission, can go haywire, leading to poor performance.
Braking System
The braking system is generally reliable, but it’s essential to keep an eye on the brake pads and rotors.
- Wear and tear: Regular inspections are crucial to avoid any surprises.
- Brake fluid: Change it regularly to maintain braking performance.
In summary, the 2002 BMW M5 is a thrilling ride, but it demands attention and care. Understanding the reliability of its key components will help you keep this performance machine running smoothly.

However, potential buyers and current owners need to be aware of its reliability aspects to ensure they are prepared for the ownership experience.
Build Quality and Materials
When it comes to build quality, the M5 is a mixed bag. On one hand, BMW is known for its attention to detail and high-quality materials. On the other hand, some components may not hold up as well over time.
- Interior: The leather and trim materials are generally high-quality, but wear can occur, especially on the driver’s seat and steering wheel.

Electronics
The electronics in the M5 can be a double-edged sword. While they offer advanced features, they can also be a source of frustration.
- Dashboard Warnings: Many owners report false warning lights, particularly related to the ABS and traction control systems.
- Navigation and Audio: The infotainment system can be outdated, and repairs can be costly.
- Sensor Failures: Common issues include failing oxygen sensors and crankshaft position sensors, which can affect performance.
Maintenance and Repair Costs
Owning a 2002 M5 isn’t just about the purchase price; maintenance and repair costs can add up quickly.
- Routine Maintenance: Expect to pay a premium for oil changes, brake pads, and other routine services.
- Parts Availability: While some parts are readily available, others can be hard to find and expensive.
- Labor Costs: Repairs at a BMW dealership can be significantly higher than at an independent shop, so choose wisely.
