Should I Trust My 2017 Forester's Transmission?
I own a 2017 Subaru Forester with a 2.5i CVT which I drive with a left foot accelerator; this is a driver's assist device bolted to the floor board; it operates the
car's accelerator via a rod/roller assembly. This car has @12,000 miles. At @7000 miles (Sept 2019) the car started shuttering and jerking; the tachometer would rev spontaneously without my pressing the accelerator (transmission slipping?). The dealership replaced the accelerator which seemed to fix the issue. I was concerned whether or not my left foot accelerator had caused this issue, but I didn't see how, neither did the installer or the dealership. Then at @11,000 miles (April 2020) the car did the same thing. The dealership had my car for 3 weeks and ultimately replaced the Transmission Control Module. Both of these repairs were covered by warranty. I recently drove a 400 mile roundtrip; I am not totally convinced the transmission is 100% fixed. Sometimes it seems the car does not smoothly accelerates in the 20 to 40 mph range; I will notice a slight stutter. Also I have observed that the tachometer will spontaneously rev when I coast downhill. The dealership says this is "normal" for its CVT transmission. Is this true? This is my first CVT and my first Subaru, but now I do not trust this car. Should I trade it now before it leaves me stranded somewhere in Podunk, Florida.
