BMW 8 Series (G14/G15/G16) Problems by Year
The modern 8 Series resurrects a legendary badge, replacing the 6 Series as BMW's premier heavy, luxurious grand tourer available in coupe, convertible, and Gran Coupe body styles. Positioned to rival the Porsche Panamera and Mercedes S-Class Coupe, it is based heavily on the 5/7 Series platform, offering blistering performance and a sumptuously trimmed cabin. In the UK, it is an exclusive, expensive vehicle to buy and run, particularly the M850i V8, but it delivers immense continent-crushing capability. It suits wealthy buyers seeking a dramatic, fast, and highly refined GT car with massive road presence.

- ✓Check the huge alloy wheels for kerb damage and cracks; the low-profile tyres provide very little protection for the rims.
- ✓Test the xDrive all-wheel-drive system (where fitted) for smooth operation; any binding or juddering at low speeds indicates transfer case issues.
- ✓On the M850i, check for any signs of coolant leaks in the V-valley of the engine, a known weak point on modern BMW V8s.
- ✓Ensure the digital instrument cluster and iDrive 7 system do not lag or freeze, as they control almost all of the car's functions.
- ✓Verify the condition of the frameless window seals; wind noise at motorway speeds is a common complaint if the windows don't align perfectly.
- ✓If buying the convertible (G14), inspect the fabric roof for wear marks and ensure the folding mechanism is completely silent and smooth.
