Hi everyone. I'm hoping someone may be able to explain something for me and if I have an issue or not. I recently purchased a 2015 forester 2.5i premium with 57k on it. I've only had the vehicle about a month and a half and while driving at times when accelerating the car sounds like its racing and like the engine is struggling but the rpms are not what the sound makes it seem like it should be at. In other words when the rpms are at 4k it sounds like their at 6k like the car is at redline. The strange thing is it doesnt do it all the time. It seems more prevalent if I dont let the car quite warmup so the blue oil temp light on the dash turns off. It operates normally when I dont sometimes also. So it's kind of hit or miss. I'm trying to find out if I have an issue or not because of the car having a 1 year warranty on it from the dealer I bought it from but I need to know what the issue could be so I know what to hold them responsible for. If a video would be helpful I can record one possibly when I drive it next. I appreciate any help anyone can provide.
