I am looking at buying a Trax (2015). I believe it has a 1.4L turbo engine. Is this a reliable engine..and does the turbo require special maintenance (I have never had turbo before)

There seems to be a reputation of engine issues along with some other issues. Some say that if you take care of it and change oil often then you might not have engine issues. I've also seen many references to value dropping "like a brick" (quotes from three unrelated posts out there.

Personally, I'd stay away from it. It'* a bottom-rung car from GM Korea built with just enough quality to get it out of warranty.
