Disadvantages of the A12XER engine
- The main problem of the engine is the low resource of the timing chain, sometimes less than 100,000 km;
- Twinport dampers last a long time, but if they break, they are very expensive to repair;
- The ignition coils here are combined into a single unit, the reliability of which is low;
- A car may not start well in winter due to a failure of the antifreeze temperature sensor;
- Oil constantly creeps out from under the valve cover and the front crankshaft oil seal.
