Hey guys, my first post here! I'd really appreciate any help you could offer me. I have a 2016 S60 with two issues.

1. For the last six months or so the brake pedal will get stuck after I press it fully; this happens about 10% of the time. After I remove my foot from the brake pedal the car will be stopped for about 1-1.5 seconds then slowly advance. The engine doesn't restart as the start stop system isn't activated when this happens.

No problems with actual braking but this issue concerns me. The Volvo dealership tried to replicate the issue with a few techs and couldn't find a problem. They said they ruled out any "issues which could put my safety in danger."

What could this be?

I was going to bring it to another dealership; any recommendations?

2. The plastic cover of my trunk latch broke and the dealership took it off and said that the piece if plastic is just cosmetic. Is this true?

I have a few months of original factory warranty left.

Thanks in advance for any advice you can offer me! I couldn't find the answers online; sorry if it's been answered before.

Welcome to the forum.
This is very strange with the brakes. Does it happen when you floor the brakes?
You wouldn't be doing that in the normal course of driving would you?
Could it be the actual pedal and the the rest of the braking system?
Could it be getting stuck in the carpet?

As for the trunk latch plastic cover it's just cosmetic. Happened to me a long time ago and was covered by warranty.
If I recall correctly it happened to others too.
I'd have the replace it under warranty.

I don't really floor the brakes. It happens if I apply constant, strong pressure to the brakes and it just gets "stuck" in the down position for 1-1.5 seconds. The car will finally move.

If the second dealership says it nothing, what would you recommend? I could bring it to the independent shop also i guess.

Thanks for the plastic cover trunk latch response also! They actually didn't replace it; they just removed it.

Does it only happen when you are stopped on hills? It might be the hill hold feature kicking in, but I think the engine starts up upon release of the brake pedal while continuing to hold the brakes briefly.

When you say the brake pedal is getting 'stuck' in the down position, do you mean if you lift your foot off the pedal it doesn't return at all or do you mean that if you lift your foot of the pedal the brakes don't release?

If its the former, there's likely something wrong with your brakes and I'd get it checked out immediately...
If its the latter (pedal returns but brakes don't release for a second or so) its most likely the brake hold feature.

I've noticed it taking over the brakes for me in situations where the road is almost flat, I'll be stopped at a light and as I take my foot off the brake I'd normally expect the car to creep forward but it doesn't for a second or so and then the brakes release and it creeps.
If that sounds familiar I'd bet its the hill hold feature that's responsible, it seems to be very sensitive to incline, I'm not sure what sensors its using to determine a 'hill' but maybe there's a sensor calibration issue in your case?

Is that Hill Hold feature something that started on the Drive-E cars?

Put simply, I don't know... The feature is officially called Hill Start Assist or HSA and has been around for a while (I found a reference on a UK V40 forum in 2012), they may have only introduced it in the US with the Drive-E cars, but you'd have to check the historical manuals to see if it references HSA to be sure.

No. We have it on our '16 V60 non-Drive-E.

I believe the latter. I'll check next time I drive it tomorrow. Suddenly I'm not remembering if the pedal stays down or not after releasing brake pressure.

It's odd that it'd be the hill start assist as this is only happening on flat ground.

At least it's a good sign the first dealership couldn't find the cause, right? They said there were no safety issues with my problem

I have an appt in a few days with a second dealership. Thanks for the response!

If you "can't remember" if your brake pedal is staying on the floor, it is not staying on the floor. That is something that you would remember and hopefully wouldn't drive the car anymore with that issue. Based on your last post, I'm 90% sure you are talking about Hill Start Assist which is a feature in our cars. You do NOT have to be on a hill for it to be engaged.

Just to clarify. When you take your foot off the brake pedal at a red light and your car doesn't immediately start moving, does it start moving when you press the accelerator?

This sounds like a very annoying "feature" and not really needed with an automatic. With a manual and DSG I can see being beneficial but I've not once needed Hill Start Assist in any automatic that I've driven. Then again, I don't live in Pittsburgh or San Fransisco.

Unfortunately I looked down in my parking spot last night and the pedal was stuck in the down position. It went up slightly and the car proceeded to go forward.

I'll try pressing the accelerator today when the presumptive brake hold assist is working. I usually just let the car start moving slowly and then press the accelerator. The issue doesn't happen all the time, like 10% of the time

It's confusing to me as the dealership already looked into it and said there wasn't any safety issue. I have an appt with another dealership in a few days.

I don't understand how the dealership could say there is no safety issue with a brake pedal that stays on the floor. Either you aren't describing your problem correctly, or you need to take your car to another shop for a second opinion. Like right away. A brake pedal should ALWAYS return after taking your foot off of it. If it doesn't, there is a very good chance that sometime soon, you will press the brakes and it will go straight to the floor and nothing will happen.

The brake pedal is NOT stuck to the floor but it does occasionally spend 1-2 seconds going from the slightly depressed position to neutral, not pressed position.

OK, this is definitely the Hill Start Assist, I have the same response when mine kicks in. Its a small movement but the HSA does hold the pedal in the brakes applied position before it releases.

This really happend to your car too? After releasing brake pressure, the brake pedal stays depressed about an inch then slowly goes up to the original, neutral position?

My car is at the second dealership right now. On another website somebody was saying it could be the master cylinder.

I had the brake fluid flushed 4 months ago at a highly rated Volvo independent shop. I don't know if this is a big deal.


This really happend

I'm going to have to check again but what I recall is that when I've had the Hill Start Assist feature activate on a hill, I can release the brake pedal and the pedal will stays depressed a small amount (presumably this is the HSA feature maintaining the brake pressure) and then as the Hill Start Assist is released (on application of gas or after a couple of seconds), the pedal rises the small amount back to the neutral position and the brakes release and the car moves. The movement on the pedal is subtle, I'm not talking about pedal dropping to the floor and staying there.

I'll give it another try when I have a chance and report back.

**EDIT** Can confirm the pedal holds about an inch from neutral while HSA is active.
