Engine and Powertrain Issues

The BMW i8 is known to have some engine and powertrain-related problems.

One such issue is a fuel leak, which can be indicated by excessive fuel smells in the car, moisture spots beneath the vehicle, and unusual fuel gauge drops.

Additionally, some i8 owners have noted issues with the interior finish, stating that it doesn’t quite live up to the standards expected from a high-end sports car.
