Disadvantages of the GM LSY engine
In order to replace a faulty temperature sensor, motors from the initial years of production were recalled;
Like all direct injection engines, it has carbon deposits on the intake valves; its timing chain resource has increased compared to its predecessor and it can travel up to 200,000 kilometers; the remaining complaints are about oil leaks and noisy operation in certain modes.
