any of you manual guys have any oil residue on the rear side of your oil pan? above the drain bolt?

Never noted it. I don't suppose you have a picture? Suspect #1 is a mess left from a sloppy oil change.

it would be quite noticable. well maybe not in stock form. I have a skid plate that needs to be removed when an oil change is done. so I can see the whole pan once it's taken off. the residue is above the drain bolt; what appears to be where the oil pan meets the block and maybe beyond... what triggered me to look was the residue on the skid plate, first time I've seen it in 24k [emoji29]

Not that I know of but will check. Do you think this may be a clue to what's going on or is this an unrelated issue you are experiencing?

it could be. a mechanic I know says there's a flaw on a cam plate on the passenger side firewall; however this is for the 86 twins with the fa20. excessive revving causes the plate to leak bc of a design flaw/factory oversight. I'm going to check that out first. I have an appointment at the dealer for radio firmware upgrade. gonna see how that goes [emoji52]

FWIW I had a 2015 XV that had similar behavior; it was flat until maybe 2.5-3k rpm then it would finally wake up (mine was a 5MT). My solution was to keep revs above 2.5-3k when trying to do anything, basically. I got rid of my XV a couple years ago and find myself swinging back to one again, so it's interesting to see that it wasn't just me noticing the lack of power/torque below 2.5/3k rpm..

Thanks Evil_ed. My problem goes a little beyond low power. It bucks and surges during acceleration. I've been monitoring with an OBDII scanner and when it acts up the timing advance goes negative very quickly. Also under acceleration the MAF sensor fluctuates back and forth from 65 g/s to the twenties. No check engine codes or lights. I've changed MAF out and symptoms did not change. Changed fuel to top tier 93 and no change. I'm starting to think I have a knock sensor issue or electronic throttle issue. Hopefully someone on these forums has encountered and solved a similar issue. Fingers crossed.

 

[Evil_Ed]

Ahh, yes that is different; I didn't have any surging/bucking issues with mine. The only change I made to mine was I swapped out the engine air filter for an AEM reusable one (non-oiled), though my understanding was that the factory air filter wasn't horrible either. I didn't mess with any intakes or exhausts because I've read that Subarus are unusually sensitive to air in/air out changes. It might be an ECU issue, maybe? A factory screwup?

Am having similar engine 'hesitation" problems. It started a few days ago, very infrequent but more or less on every gear of my 2018 6MT Premium 21,000 miles. Had service appointment today for HU and on my way there the car was running smooth, nothing whatsoever. Surprise, surprise. I asked for a check up, but they just took the car for a ride and came back with the same result as mine today: no problem.

Hopefully they didn't cause any damages to clutch/engine etc, I've forgotten to turn my dashcam off so now I know that they rode my car like they would in the NASCAR trials. Saved the dashcam recording to PC just in case.

So I'm puzzled about the engine stutter, that day when I first noticed it was very, very hot. Will see.

I have a 2019 CrossTrek, base model with the 6MT. I get this same issue and it's making me crazy. I drive 100 miles per day and it's so intermittent I haven't been able to nail down the conditions that cause it. Where can I get a scanner to monitor this because, when it happens, there's no "check engine" light that comes on so it's not "throwing codes" such that it would show up.

Has anyone pushed this issue with a corporate level above their dealership?

I'm about to......writing to SOA tonight. I'll keep all posted on response. Wouldn't hurt for us all to do it I suppose.

I wrote to them, waiting for a response. I will update this thread when I hear back.

I use the Torque Pro app with a cheap Amazon bluetooth OBDII device. Whole setup ran about 20 bucks. I think it works great, lots of capability.

Wanted to close the loop on my experiences. I believe my bogging issues were caused by overfilling of the oil when the dealer was doing service. The outgoing 2.0 had a larger oil capacity than the 2018 which I believe was a contributor. Since I started changing my own the problem has not come back. Hope this helps someone in the future.

Have you taken the car in for this new pcv replacement recall? If I understand the recall this pcv valve is broken and allowing oil into the combustion chamber from time to time and that could cause the missfire feeling we're experiencing. I'm going to try and take mine in for the inspection next week.

There haven't been any reports here yet of a PCV valve actually being broken. It seems like it's more of a precautionary recall. Also, if the valve did break off it wouldn't let oil in - quite the opposite...

Hi,. I did take it in for the recalls. However the hesitation had been gone for 5000 miles prior to this when I corrected my oil level.

2018 6MT. I've experienced all of the symptoms mentioned in this thread. Right now, however, it's running great. Why? Because it's winter.
I've tracked this long enough to expect it to happen when it's hot outside. From October through April I have no problems, but when the weather heats up, the symptoms return. Having the A/C on will make it worse, but that may just be because the A/C draws a few HP away. Overall, if it's hot, the symptoms are there, whether the A/C is on or not.
Please don't confuse this problem with a lack of power. The engine is always weak, and that's something you know you have to deal with in this model. The bottom line is: the engine performs very differently on hot days than on cool days.

This echoes my sentiments and experiences exactly.

I have a 2018 manual premium. I drive in upstate NY and have the exact same issues to the T. I suspected it was humidity and that it was fuel mixture related, not mechanical. I contacted the dealership and was told that they had never heard of any issues. Of coarse... I have 15k miles on it now and it is getting no better or worse. If anyone has a definitive answer please let me know!

Is yours seasonal?

It seems to be. Last year was a dry winter so not that noticeable. This year we’ve had 40 degree days with rain for that last 2 months and it has been noticeable. Definitely summer prominent though. If enough of us scream they’ll probably come out with a new reprogram.
