Acceleration intermittently stops while depressing gas pedal

Asked by Greg Jul 28, 2023 at 09:34 AM about the 2016 Subaru Forester 2.5i Limited

Question type: Maintenance & Repair

My 2016 Forrester with ~114k miles has started having an
issue with the acceleration where I'll be driving fine and all
of a sudden while pressing the gas pedal I just start losing
acceleration. If I keep the pedal pressed it doesn't start
moving, but if I take my foot off the gas for even a second
and press again it starts moving again like there is no
issue. There are no sounds other than normal engine
revving when this happens and no lights on the dash come
up.

I brought it in to the dealer, and after about a week they
couldn't reproduce or diagnose the issue but after less than
50 miles when I got it back it started happening again.

Anyone else have this issue? Anyone know what it could be
or how to fix it? I did see a similar issue on here when I
searched it but that was a 2013 sonata so I'm not sure if it
could be the same problems since it's a different make and
model.

I’m having the same issue with my 2014 BMWX3. Just stops acceleration- exactly like you said. It won’t move for a lil while- I’m a sitting duck. No forewarning, no engine light come on either. I run the checks & every things checks out fine. It’s happening on the freeway too, so it’s pretty scary.

It sounds like the engine has to be overheating to produce the condition. You'll have to take the car to a mechanic when this is actually happening, before the engine cools off. Could be a throttle problem, leaking injectors, etc.
