Hi Sir,

Not entirely sure if this area is the right one regarding my concern. I have a Chevrolet Captiva 2015 A/T Diesel and since January this year I started to notice that my engine is under-powered, and is struggling to accelerate even when my foot is halfway down on the accelerator. Also with that, the car is also emitting thick black smoke mostly when I accelerate and at certain times even if the car is in idle. I approached Chevrolet Batangas CASA but their service fees are quite pricey and not entirely sure if their fix would be effective. I brought in my car to Rapide and they flushed the ATF. The acceleration of the car is a bit better now but still lagging in power. The car is going on 76000km now and is almost 5 years of use. I need your help or input on this please. Thank you.
