Why Some Bmw M5 Years Are Risky
Not every M5 is built equally. Some years stand out for engineering mistakes, unreliable parts, or poor quality control. When it comes to high-performance cars like the M5, even small problems can lead to huge repair bills. BMW has made big changes in engine technology, electronics, and design from one generation to the next.
Sometimes, these changes bring new issues.
Most of the “bad” M5 years are not about style or speed—they’re about reliability. Owners report engine failures, transmission problems, and expensive electronics that break too soon. In a car like the M5, repairs are never cheap. Understanding which years are trouble-prone can save you thousands of dollars and countless headaches.
5 Bmw M5 Years To Avoid
Let’s look at the five BMW M5 years you should be very careful about. For each year, you’ll see:
- Why it’s considered risky
- The main problems owners face
- Real-world repair costs
- How it compares to better years
1. 2000 Bmw M5 (e39)
The 2000 BMW M5 marked the early years of the E39 generation, often celebrated for its handling and classic looks. However, the first production year came with several teething problems.
Common Issues:
- VANOS failures: The variable valve timing system called VANOS is famous for failing early. Replacement is expensive.
- Rod bearing wear: Early E39 M5s had rod bearing issues that could lead to catastrophic engine failure if not fixed.
- Cooling system weaknesses: Radiators, water pumps, and expansion tanks failed more often than expected.
Owners often report that repairs can easily exceed $5,000 for major engine work. Even routine items like clutch replacement are pricier due to labor-intensive designs.
What makes 2000 worse than later E39s? BMW made small but important changes in later years. The 2001–2003 models had improved engine internals and more reliable VANOS components. A 2000 M5 usually needs more preventive maintenance or expensive retrofits to reach the same level.
Non-obvious insight: Many buyers skip pre-purchase inspections because the E39 looks simple. But the 2000’s unique issues mean an expert check is absolutely essential.
2. 2006 Bmw M5 (e60)
The 2006 M5 is a car that divides opinions. It introduced the wild V10 engine and SMG III transmission, promising Formula 1 thrills on the street. Unfortunately, it delivered just as many headaches.
Main Problems:
- SMG III transmission failure: The single-clutch automated manual is jerky, unreliable, and extremely costly to replace.
- Rod bearing failures: Like the E39, the E60’s V10 suffers from rod bearing problems—sometimes as early as 60,000 miles.
- Throttle actuator failures: These small electronic motors control the engine’s throttle and are known to fail regularly.
- Excessive oil consumption: Many owners report burning a quart of oil every 1,000 miles or less.
Typical repair costs: A failed SMG pump can cost over $4,000 to replace. Rod bearing jobs can cost $6,000 or more. Throttle actuators run $1,200–$2,000 each, and there are two.
The 2006 M5 stands out as the worst year for SMG transmission problems. Later E60 M5s had incremental improvements, but 2006 models seem to have the highest rate of failures.
Non-obvious insight: Many buyers think low-mileage 2006 M5s are safe. In reality, the issues are age-related, not just mileage-related. Even garage queens can develop expensive problems.
3. 2007 Bmw M5 (e60)
The 2007 M5 carried over many of the same issues as the 2006 model. While BMW fixed some minor bugs, the big problems remained.
Key Issues:
- SMG transmission glitches: Still the number one complaint—delays, errors, or total failure.
- Electronics gremlins: The iDrive system and other electronics are more complex and less reliable than earlier generations.
- Rod bearings and throttle actuators: Continuing to cause expensive breakdowns.
Why avoid 2007 if it’s so similar to 2006? In 2007, BMW increased the number of electronic features. This made the car more advanced, but also increased the risk of electrical problems. Owners often experience random warning lights, failed sensors, and mysterious “limp mode” incidents.
Repair costs: Expect to pay $2,000–$6,000 per major repair. Some owners report annual repair bills that match the cost of a used car.
Non-obvious insight: Extended warranties rarely cover all the electronic failures. Even dealers sometimes struggle to diagnose the root cause, which means long repair times.
4. 2013 Bmw M5 (f10)
The 2013 M5 introduced a brand-new turbocharged V8 engine and a dual-clutch automatic transmission. While it was faster and more fuel-efficient, reliability took a hit in the first year.
Main Complaints:
- Turbocharger issues: Early F10s often suffered from turbo failures, wastegate rattle, and oil leaks.
- Fuel system problems: High-pressure fuel pumps and injectors are common points of failure.
- DCT (dual-clutch transmission) faults: Jerky shifting, warning lights, and outright transmission failure are not rare.
2013 stands out as the “risky” year because BMW was still working out early bugs with the new engine and gearbox. Later years saw many of these problems reduced.
Repair costs: Turbo replacement can cost $5,000–$7,000. High-pressure fuel pump failure is around $1,500. DCT repairs can run up to $8,000 if out of warranty.
Non-obvious insight: Many 2013 M5s are sold “cheap” because sellers want to offload problem cars before the next big repair hits.
5. 2018 Bmw M5 (f90)
The F90 M5 brought all-wheel drive and massive power, but the first model year (2018) had its share of trouble.
Frequent Issues:
- Early software bugs: The new all-wheel-drive system and electronics had glitches that affected drivability and reliability.
- Oil leaks: Some engines developed leaks at the oil pan gasket and turbo lines.
- Cooling system issues: Water pumps and radiators had higher failure rates in 2018 than later years.
2018 was a “learning year” for BMW with the F90 platform. Many owners faced repeated trips to the dealer for software updates and hardware replacements. Later years have proven more reliable after BMW fixed the bugs.
Repair costs: Oil leak repairs can cost $2,000–$3,000. Software or sensor issues may require repeated dealer visits, which add up in cost and frustration.
Non-obvious insight: Many 2018 M5s have been updated with the latest software, but not all. A car without the newest updates is much more likely to have electronic issues.

What Makes A “bad” M5 Year?
Some people wonder why only certain years are high-risk. The truth is, each “bad” M5 year shares three things:
- Major design changes. BMW often introduces new engines, transmissions, or electronics in these years.
- First-year bugs. Early production runs have more factory defects.
- Expensive parts. When things break, the cost to fix them is much higher than on other cars.
These factors make some M5s much riskier to own unless you have a deep wallet and lots of patience.
Common Problems And Their Impact
Let’s look at the biggest issues behind these “bad” years, so you know why they matter.
Engine Problems
BMW M engines are advanced and powerful, but they have weak spots in certain years.
- Rod bearing failure: This can destroy the engine. It’s most common in the 2000, 2006, and 2007 M5.
- VANOS/valve timing failures: Found in older models, especially 2000.
- Turbocharger problems: Especially on 2013 M5, leading to loss of power and expensive repairs.
- Oil consumption: V10 engines (2006–2007) often burn excessive oil, needing frequent top-ups.
Transmission Issues
The M5’s advanced transmissions often become liabilities.
- SMG transmission failure: 2006 and 2007 models are famous for this. Repairs are expensive and parts are hard to find.
- DCT glitches: Found on the 2013 M5. Not as costly as SMG, but still a headache.
Electronics And Software
Modern M5s have complex electronics. Early versions of new systems often break.
- IDrive and sensor failures: Especially in 2007 and 2018. Can cause the car to go into “limp mode.”
- Software bugs: 2018 models often needed updates to work correctly.
Cooling And Oil Leaks
BMW’s cooling systems are a known weak spot, and oil leaks are common in certain years.
- Water pump and radiator failures: Seen in both old (2000) and new (2018) M5s.
- Oil leaks: Expensive to diagnose and fix, especially on turbocharged engines.
How To Avoid Buying A Problem M5
If you’re still interested in one of these years, it’s possible to get a good car, but you need to be careful.
- Demand service records. Only buy an M5 with full history showing all major maintenance, especially for known problem areas.
- Get a pre-purchase inspection. Choose a BMW specialist who knows the M5’s unique issues.
- Check for updated parts. Ask if the car has had rod bearings, VANOS, SMG pump, or turbochargers replaced or upgraded.
- Avoid “cheap” cars. A low price often means the seller is passing on a big repair bill.
- Look for cars with extended warranties. These can save you from major out-of-pocket costs.

Cost Of Ownership Compared
Many people buy a used M5 thinking it will be “just like a 5 Series. ” The reality is very different. Here’s a side-by-side look at annual ownership costs for “bad” M5 years versus regular 5 Series and “good” M5 years.
| Car Model/Year | Average Annual Maintenance | Chance of Major Repair (%) |
|---|---|---|
| 2006 M5 (E60) | $3,000 | 40% |
| 2013 M5 (F10) | $2,800 | 35% |
| 2018 M5 (F90) | $2,200 | 20% |
| 2014 535i (Regular 5 Series) | $1,000 | 10% |
| 2015 M5 (F10, safer year) | $1,500 | 15% |
The difference is clear: “bad” M5 years are much riskier and more expensive to maintain, even compared to other BMWs.
What To Do If You Already Own A “bad Year” M5
Not everyone reading this is shopping—some already own one of these years. If that’s you, here’s how to reduce your risk:
- Stay on top of maintenance. Delaying an oil change or ignoring a warning light can make things much worse.
- Replace known weak parts early. For example, change rod bearings at 60,000 miles rather than waiting for failure.
- Find a good independent BMW shop. Dealer repairs are more expensive, and not all shops know the M5’s quirks.
- Join BMW forums and owner groups. Many repairs have “DIY” guides that can save you money and point out early warning signs.

Real Owner Stories: The Hidden Costs
Many M5 owners go in expecting a few repairs, but the stories from “bad” years are cautionary tales.
- One 2006 M5 owner reported spending $16,000 in three years on SMG and engine repairs—almost as much as the car’s value.
- A 2013 M5 driver had both turbos fail under 70,000 miles, costing over $8,000 out of pocket because the car was just outside warranty.
- Multiple 2018 M5 buyers complained about repeated dealer visits for “check engine” lights and software updates, with some issues taking months to resolve.
Non-obvious insight: Many owners sell their M5 after a major repair. This means the “good” cars are usually more expensive, while the cheap ones may be ticking time bombs.
How Bmw Has Responded Over The Years
BMW does listen to feedback and often fixes the most serious problems in later model years. Updates can include:
- Stronger engine parts (rod bearings, pistons)
- Redesigned transmissions (switch from SMG to DCT)
- Improved cooling and software updates
That’s why buying a later-year M5 from each generation is usually safer.
Should You Ever Buy A “bad” M5 Year?
There’s no such thing as a perfect car, and some enthusiasts still seek out these risky years for their unique engines or driving experience. Here’s when it might make sense:
- You’re a skilled DIY mechanic. If you can do your own repairs, the cost drops dramatically.
- You want a project car. Some people enjoy restoring and upgrading their M5.
- You find one with all major repairs done. Occasionally, an owner spends the money to fix every weak point.
For most buyers, though, the safer years are a better bet.
