Body styles: Coupe, Convertible, Gran Coupe
Drivetrains: Rear-wheel drive (RWD), xDrive (All-wheel drive)
This assessment for the 2025 model year is based on the reliability trends and common issues observed across the G15 generation since its introduction. As 2025 is a current model year, long-term reliability data for specific model year changes is not yet available.
Trust score and verdict
Trust score: 70 / 100
Verdict: RECOMMENDED
Recommended and avoid configurations
RECOMMENDED CONFIGURATIONS (THE 'BUY' LIST)
840i (B58 I6 engine) with ZF 8-speed automatic
- Excellent balance of performance and efficiency
- Highly reliable B58 inline-six engine
- Robust and smooth ZF 8-speed automatic transmission
- Lower running costs compared to V8 models
CONFIGURATIONS TO AVOID (THE 'LEMON' LIST)
M850i or M8 (N63/S63 V8 engine)
- Higher potential for oil leaks (valve cover gaskets, oil pan gaskets) as the vehicle ages
- More complex cooling system with higher failure rates for components like coolant lines and pumps
- Increased risk of turbocharger-related issues due to higher heat and stress
- Significantly higher maintenance and repair costs due to engine complexity and specialized parts
Used car buyer guide (Australia)
Common problems & platform risks
For the Bmw 8 Series model year 2025 (2018-Present), recurring issues often cluster around specific engines, transmissions, and shared chassis electronics. The trust score reflects how often serious powertrain or drivetrain problems show up in real-world reports versus routine maintenance. Always verify with a pre-purchase inspection and service history.
What to inspect before you buy
Use the platform-wide inspection list above for leaks, rust, suspension wear, and electronics. On a test drive, listen for drivetrain noises, check transmission behaviour when hot, and scan for warning lights. In Australia, heat and urban short trips can accelerate wear—factor in climate-appropriate servicing.
Best engine or trim to target
A typical starting point is configurations similar to: 840i (B58 I6 engine) with ZF 8-speed automatic. Cross-check against the recommended list and your budget; the "sweet spot" often balances fewer reported failures with parts availability.
Configurations to be cautious about
Sources frequently flag higher risk around: M850i or M8 (N63/S63 V8 engine). That does not mean every car fails—use it as a prioritisation list for inspection and price negotiation.
Ownership cost signals
Higher reported failure rates usually mean more workshop time and parts cost. Before buying, get quotes for common jobs on this generation (timing, fluids, suspension, transmission service) from an independent specialist familiar with the brand.
PLATFORM-WIDE QUIRKS & INSPECTION POINTS (ALL MODELS)
- Electronic glitches and infotainment system issues (iDrive)
- Sensor failures (e.g., parking sensors, ABS sensors)
- Premature wear of suspension bushings and control arms, especially on models with larger wheels and performance tuning
- High cost of replacement parts and specialized labor for repairs
- Potential for issues with advanced driver-assistance systems (ADAS) sensors and modules
