2021 delayed response/bucking

Continuing the discussion from 2010 Subaru Forester - bucking for no reason:

my 2021 forester has a delayed response when i drive it after it sits for extended periods of time (like overnight),at low speed the rpm will jump past 2 then go down then the vehicle will accelerate.it is worse when the outside temperature is below 60.the dealer drove it,had the same experience and did a TCM update,said it was good,but 2 days later same issue.2023-06-15T05:00:00Z

I’d post this on Forester forums, see if others are having this problem. You’ll need to keep after the dealer, it’s still under warranty, right?

If the dealership is unable or unwilling to repair this problem on a 2 year old vehicle that is covered by multiple warranties, it is time to “kick it up a notch” by contacting Subaru of America at the corporate level. Contact info can be found in your Owner’s Manual. Just be sure to keep it civil with the corporate folks.

Might want to have them check the idle air control.

extended warranty gold package

i have been in contact with them and dealer. dealer seems to want to pass the buck to subaru,subaru wants to pass to dealer

ok and thanks.

How many miles are in the Subaru? The dealer is the factory representative. If you are still in warranty and this dealer won’t help you, try another dealer. Also get a printed receipt for every visit. Also communicate by email if possible to have a written record.

Is this most noticeable in slow speed neighborhood driving? If so, suggest to try a can of Techron fuel injector cleaner in the gas tank. Unlikely to hurt, could help. If it helps, but not enough, try another can. (Ask dealership before trying, about warranty implications.)

TR580/TR690 transmission? Ask dealership if they have this bulletin. You might be able to see it just by Googling the number below.

16-132-20R

That might in fact be good news, seems to indicate both parties believe something indeed is wrong.

Is car really 2021? And dealer can confirm issue? And dealer blames Subaru? I’d trade it in for known issue that can’t be fixed. If true, then it seems there is a design issue.

39000 miles

I googled the code you stated, that is 99% what I’m experiencing! I don’t understand why this is such a dilemma! Thank you thank you, you’ve given me some ammo and info to share with the service people

I expect the problem is that there exist some owners who don’t like the way their CVT “feels” so complain to dealership something is broken, when in fact that’s just the way that particular CVT model works. So it is hard for dealership/manufacturer to distinguish when something is actually broken vs just doesn’t feel like owner wants it to feel.

For each symptom similar to chain slip described in that service bulletin, the remedy is to update the TCM software and that has been completed.

Communicating the condition seems to be a problem, “delayed response” could be anything and might be the result of normal engine performance.

I agree, One of the top dealers in Nashville lost there GM license (bailout mess) and changed everything over to Hyundai/Subaru of Nashville, the employees hated it and it went down hill fast, Never seen anything that bad, seemed like any employees that stayed just stopped caring and the parts and service department went to crap… I worked with a Master tech that had just bought a WRX STI from them and the cel came on with a few thousand miles, he checked it out and then took it to the dealer for warranty and they gave him a loaner car but kept his STI for over 4 months given one excuse after another… It was a cam sensor or something he could have done in a few hours… Parts were on the shelf… We worked within walking distance from them so he did drive buys all the time not seeing it worked on… He finally, after being nice cause we bought a lot of parts from them for years and years, called Subaru America and went off, his car was repaired in 2 days after that… Funny how that happened…
I also know of many customer complaints about there service department since then…

But the Old DW Subaru south of Nashville took care of there customers like they should have and took a lot of customers from Nashville because of it…

My point is, it is the people working there most of the time, not the company that makes the difference… 3
Try a different dealer if one is close enough to take it to…

My uncle had some sort of problem with his 1960 New Yorker convertible, and the dealer assured him–twice–that they had fixed it, but they had not done so. Then, he remembered that when he went to retrieve his car, it was always parked in the same place that he had left it when he dropped it off.

So, on his 3rd visit, he placed a large pebble on top of one of the tires. Sure enough–when he went back to retrieve it, the pebble was still there. He sarcastically congratulated them on providing excellent curb service, since they never bothered to move his car from the curb where he had parked it, and–of course–he never went back.

He found another dealership that resolved the issue on the first try, and because of their superior service, he bought a new Imperial LeBaron from them 2 years later, and a few years after that, he bought another Imperial from them.

The original “curb service” dealership went out of business a few years later
