BMW i8 (I12) Problems by Year
The BMW i8 is a futuristic plug-in hybrid sports car that still looks like a concept vehicle on the road today. Positioned as a technology showcase, it utilizes a lightweight carbon-fibre reinforced plastic (CFRP) tub, a small 3-cylinder turbo engine, and an electric motor to deliver sports car performance with eco-car emissions. In the UK, it has a dedicated enthusiast following, but requires specialist BMW 'i' technicians for any repairs, particularly regarding the high-voltage battery or complex hybrid drivetrain. It suits early-adopters and style-conscious buyers wanting a striking, unique daily-drivable sports car.

- ✓Check the high-voltage battery health using the iDrive hidden menu to see the 'Max Kappa' reading, indicating degradation.
- ✓Inspect the spectacular dihedral 'butterfly' doors; ensure the gas struts hold them up securely, as they weaken over time.
- ✓Test the air conditioning to ensure it blows ice cold; the A/C compressor also cools the high-voltage battery, and a failure can be catastrophic.
- ✓Look for any cracks or damage to the CFRP (carbon fibre) body shell or sills, as repairs require highly specialized, expensive composite work.
- ✓Verify the petrol engine starts seamlessly when the battery is depleted or when switching to 'Sport' mode.
- ✓Check the condition of the incredibly narrow, bespoke 'eco' tyres; they offer little kerb protection for the large alloy wheels.
