- The first years of production were failures of the electric supercharger cooling pump;
- Engine speed may fluctuate due to throttle fouling or ignition coil failure;
- The unit is completely aluminum and overheating is strictly contraindicated for it;
- The remaining problems here are related to oil leaks and especially at the junction of engine sections.
