Syzygy05 Posted April 17, 2018 Share Posted April 17, 2018 Every morning or anytime I turn on the car after it's sitting cold, the car jerks as I shift into reverse or drive. It's around 30-40 degrees here in NJ. The car is a 2017 Legacy with only 9500 miles on it. The car doesn't jerk if I let it sit for about 1-2 minutes, just long enough for the RPMs to drop close to 1000. Is this damaging my transmission?

Pilot1226 Posted April 17, 2018 Share Posted April 17, 2018 Car is stationary when you are changing gears right, not continuing backwards when you throw it into drive? Link to comment Share on other sites More sharing options...
crudzinskas Posted April 17, 2018 Share Posted April 17, 2018 So your car jerks it when you give it the D. Interesting But in all seriousness, I wouldn't worry about it hurting your transmission. As you mentioned it's probably a result of the higher RPMs the car runs at when cold and not warmed up yet. If you are still worried you can always go to/call the dealer. You still have a lot of warranty left at only 9500 miles. Im not sure when you bought the car, but also consider if the jerk has gotten wore over time or if it was like it from the factory.

magnetman Posted April 17, 2018 Share Posted April 17, 2018 My 2016 Legacy premium also does this. I have thought it as normal now, but it is very annoying nonetheless. If you get the problem resolved, let me know so I can get mine fixed as well. Link to comment Share on other sites More sharing options...
SubieN8 Posted April 17, 2018 Share Posted April 17, 2018 My 15 2.5 didn't do this, nor does my 18 2.5, even when cold. I assume the dealer will tell you "it's normal". But it's worth having it doc'd by the dealer, so that if it gets worse or breaks down the road, they're more willing to give you a break on cost if outside of warranty.

Tr00b Posted April 17, 2018 Share Posted April 17, 2018 Supposedly there is a transmission and engine programming reflash for the ECU available for the 2016's at the dealership. My next oil change will be at the dealer and I'm hoping to get this flash. Mine also does this and its pretty annoying. Link to comment Share on other sites More sharing options...
Badbee Posted April 18, 2018 Share Posted April 18, 2018 I was thinking of starting a thread like this. I find my 2018 3.6r is a pain to manage at low parking lot speeds when cold. Note we are talking Seattle cold (50F) not east coast cold. It takes really careful brake release to avoid lurching forward or back and hard to keep under 15 mph. My old cars (non-Subaru) weren’t like this, at least not to this degree. Do folks just adapt to it? Link to comment Share on other sites More sharing options...
Pleiades 3.6R Posted April 18, 2018 Share Posted April 18, 2018 I guess people don't warm up their cars anymore? Link to comment Share on other sites More sharing options...
Syzygy05 Posted April 18, 2018 Author Share Posted April 18, 2018 I'm definitely going to get it looked at by the dealer and see what they have to say. Generally it only happens with cold weather. I haven't really noticed it in the summer months. I bought the car August 2017. I'll keep you guys updated though since a few folks are experiencing the same situation.

Tr00b Posted April 19, 2018 Share Posted April 19, 2018 I guess people don't warm up their cars anymore? If I pull out of the heated garage, yeah. or am trying to evade capture by Russian operatives. But mostly pulling out of a heated garage. I'm such a lush. Link to comment Share on other sites More sharing options...
magnetman Posted April 21, 2018 Share Posted April 21, 2018 So I had my 24K oil change today and had them look at some issues. They said the petal jerk was ‘within normal limits’ and that I needed to fully warm the car after every start between 2-10 minutes before shifting into gear. They said no ECU reflash was available for the transmission or engine as well. So I guess I will continue to live with it until a fix happens or I sell the car.

Pleiades 3.6R Posted April 21, 2018 Share Posted April 21, 2018 I'm completely at a loss as to why people think this is a problem. If someone woke you up and a few seconds later wanted you to take off running laps you probably wouldn't perform great either. Engines/mechanical devices need a minute to warm up and get fluids moving, just like you. Take a minute or two and let it warm-up or buy a remote start. Not rocket science but it is science.

Craig01b Posted April 23, 2018 Share Posted April 23, 2018 Yup, my 2018 3.6 jerks a little when rpms at idle are a little high.....not like my old Chevy when you had to give it a blip to make the automatic choke come off, but it goes away when warmed up.. not a problem, but the nature of the beast I think.
