I was driving yesterday in dynamic mode. I accelerated while making a turn, and the car failed to upshift. Instead, it stayed in gear and revved really high. I thought that I may have accidentally put it into manual shift mode, but I checked, and this was not the case. I let the RPMs settle down, and tried again, but it did the same thing. Fortunately, there wasn't any traffic around, so I pulled over and brought the car to a stop. I put it in park and then back into drive again, and then it was fine. Thank god this didn't happen to my wife. She would have really freaked out. Has anyone else experienced something like this?

Okay - if it doesn't shift it seems like software issue.
Cant be a "design feature" - even when doing track racing you do not want to get stuck on the rev limiter no matter if you are in a turn.
Should be possible to fix. Have you asked if there are any new SW release for the TCM or ECM?

For you guys who are having the issue - are your vehicles up-to-date software wise?
Mine is not up to date. I have an appointment on the 19th to finally have them do the big November update. While the car is in the shop, I assume they will also address any additional big fixes, TSB's, etc ...

Good luck, gweempose. I personally would ask the Service Dept. to review the bulletins and journals for applicability and resolution.
FWIW, in the aviation world, it is trust and verify (that it was checked and logged even if not applicable). AD's (airworthiness directives) must be checked off during scheduled service and noted in the maintenance records even when not applicable based on model or serial number (akin to VIN). Service bulletins are the responsibility of the aircraft owner (and tend to be optional until they rise to the level of an AD). I tend to be a bit anal when it comes to service on most anything that has wheels, propellers or turbines.
It could be a "design" feature. Again not saying 100% but i know that certain CUVs like the acura mdx have something called Shift Hold Control "which is intended to avoid disrupting the chassis or power delivery. delays up-shifting when the driver accelerates through a curve."
Since some people are posting that this is in dynamic mode, it seems the two are linked and possibly in there by design. Now if the car is accelerating without driver input thats something totally different. But if the car is not upshifting but your are in control of the throttle something to consider.
Ok. But it seems that gear is holding even after turning which is not a desired functionality.
I would make a claim noting the safety issue not being able to build speed after turning out on a highway from e.g. a gas station etc.
Good luck! Im sure this willbe fixed.

Holding a lower gear such that the driver cannot accelerate beyond a certain speed is clearly a dangerous fault and a matter for the dealer's immediate attention.

I believe it's meant to hold the gear until redline and then shift. If it doesn't hit red line, it won't shift. I don't like it, so between this and the poorer fuel economy, I'll stick to comfort mode. I occasionally use dynamic from a stop but then switch to individual (comfort) after accelerating past whoever I wanted to pass. Volvo may change this, but I'm pretty sure it's programmed to do exactly what it's doing.

In my T8 I've tried AWD, Power and Hybrid modes and can't repro this.

Been lurking around here for a few months. I've had my Momentum since late September and when I saw this thread I had to register. Let me preface by saying I LOVE this car!
This did happen to me on two occasions though. I thought it was a fluke. Both times was from a full stop at a light. I'm not completely certain what direction I turned in, but I know one was a left turn. The other one may have been a right, memory is fuzzy.
I switch to dynamic when the conditions necessitate a little more "getup" so it's a little concerning that this is happening, whether it's a buggy feature trying to hold gears through a turn or otherwise a bug. One of the times this happened I was in an intersection that turned yellow with me in it as I was making a left on a fairly busy business route. Relative to the speed of the traffic I basically "stalled out" coming out of the turn and I was nearly rear ended by the car behind me. To be fair, the other driver probably sped through and ran a red, but had I kept accelerating with the rest of the traffic, as I was trying to do, there would have been no issue at all.
The car has spent about two weeks in the shop for minor fixes. I wonder if there's any way to force Volvo's hand to look into this generally without me losing my car for an indeterminate period of time?

I've had my T6 Inscription since 12/15. I had read this thread before but never experienced the behavior personally -- until yesterday. It was just as has been described by others here. I put it in Dynamic mode sitting at a stop sign, and then turned 90 degrees (once left and another time right). The engine revved and simply never shifted. It was a behavior just like you were in manual shift mode but never shifted. Except, I wasn't in manual shift mode. I was in auto and Dynamic mode.
I rarely drive in Dynamic mode, which I'm sure is why it took me 45 days to experience this glitch. I say glitch because after experiencing it first hand, I cannot fathom this is intended/by design behavior. It was very concerning and yes, dangerous (with other vehicles behind).
I guess I'll have to take her into the dealer and see if they can help diagnose the issue. I'm not optimistic, though, as my local dealer has already admitted they are "learning" how to service this vehicle.

Holding gear while turning is how not to upset the balance of the car.
However the more i read this thread the more i feel this is a glitch. To make sure, do you guys stuck in the same gear after release the gas paddle or bounce the rev limit in a straight line when this happened?

Not sure I totally follow your question. For me, the only way to get the vehicle to shift was to totally let off the gas, and that triggered a correction.

While this behavior seems to be triggered in Dynamic mode and turning from a stop (in either direction), it continues well beyond the completion of the turn.

Yeah sorry to all the people who want this to be the proper behavior by design but I call bs. Its only happened to me a few times so I don't think its a crisis either, but since its only happened a few times, and not every single time I drive in dynamic, its clearly not how it is "supposed" to act. The normal behavior in dynamic is holding gears to a degree but it absolutely does not "hold them until redline" by design. Sorry it just doesn't!

This happened in my V60 Polestar, under the same conditions; from either a standstill or starting off on a very low gear (1st or 2nd) while in Sport mode and making a sharp turn under almost full acceleration. It happened to me once and I was not expecting it. Mindful of this thread, I tried it 3 other times and the same thing happened 2x.
Once, I lifted off the throttle and it shifted. The other time, it did not and had to push the lever back to D and then back to S; it shifted properly.

FWIW, when this happened to me 2x yesterday, it was a normal (not sharp) 90 degree turn (once right and once left). And, it was no where close to full acceleration. It was a normal turn with average acceleration. I just happened to be in Dynamic mode, and the transmission never shifted.
I'm not hitting the panic button (mainly because I use 95% Comfort mode), but this is most certainly not normal or by design. If it is, then it's horrible and dangerous design.
