Audi Q8 (4M8) Problems by Year
The Audi Q8 is the stylish, coupe-SUV sibling to the Q7, offering a wider, more aggressive stance and a slightly sportier driving experience. Positioned at the very top of Audi's SUV range, it competes with the BMW X6 and Porsche Cayenne Coupe, bringing massive road presence, huge running costs, and premium insurance premiums. It is vast and complex, sharing the same 48V mild-hybrid architecture and dual-screen infotainment as the A6 and A7, making warranty coverage highly recommended for used buyers. It suits affluent buyers who want the practicality of a large SUV but prioritize striking, aggressive design over absolute cargo volume.

- ✓Look out for 48V electrical system faults, specifically the Belt Starter Generator (BSG) failure, which will drain the battery and leave the car stranded; verify if it has been replaced under warranty.
- ✓Test the dual-touchscreen MMI system thoroughly for responsiveness and ensure the haptic feedback works evenly across both screens.
- ✓Check the frameless doors for excessive wind noise at motorway speeds, which may indicate worn weather seals or poorly aligned window regulators.
- ✓Inspect the enormous alloy wheels (up to 23 inches) for kerbing and check tyre tread depth; replacing a set of premium tyres is exceptionally expensive.
- ✓Ensure the adaptive air suspension adjusts smoothly between modes without sagging or throwing dash warnings, as replacing the complex struts is a huge expense.
- ✓Verify that the automatic gearbox downshifts cleanly when slowing to a stop; some owners report clunky or hesitant downshifts that require transmission software recalibration.
