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.
