Hello

I recently picked up my XC40 T3 Auto R Design with all bells and whistles. I am very happy with the car and feels very premium and solid to drive. There is though one two small issues which ruin my 100% perfect feeling.

When i am driving in the city and brake towards a full stop, like in traffic lights, once the car is fully stopped i can feel a slight vibration as if the Auto Start/Stop function is enabled and the car is switched off. Although i have this function disables i can still feel that. I also notified that if the road is slightly downhill it doesn’t do that. It is a little hard to explain and enlgish are not my native language. It feels like a short tremble and then it stops. Maybe 1-2 seconds it lasts.

Does anyone else experiences something similar?
I want to go back to my dealer and drive the demo car because i think it didn’t do that

Other issues:

1. iPhone. I can’t display text messages. Options are all grey
2. Having my iPhone Bluetooth connect every like 5 seconds i hear like a notification sound. Didn’t happen with my old iphone

What is the Auto/Stop function that you refer too? Is is the stop start emissions function that turns off the engine or is it the function that activates the brake?

Just trying to get to the bottom of the issue. If you disable the auto start/stop each time you get in the car then the engine won't switch off. So how do you determine if there is a slight vibration if you have the engine on.

Could it be the Auto brake?

Also, none of my business I know, why do you disable the Auto Stop/Start each time you start a journey? Why not use the functionality, reduce your engine emmisions and help the environment?

I disable it because in heavy traffic switching on/off 5 times every minute i am not sure if that helps the environment but to my belief it definitely doesn’t help my car in longterm.

I also need to point out that i fee the same tremble once i release break pedel and car starts moving.
I don’t know if this has to do anything with the gearbox.

The autohold i have it also disabled. Can’t get used to that. When i am using it i find myself also pressing the break pedal

Mmmm...sorry it's not something I've experienced, perhaps someone else can join in.

I have autohold switched on as I find it useful not to have to keep my foot on the brake. I switch it off, using the centre console green light button at the end of a journey if I have to maneovre carefully.

I have the start/stop system activated as in slow traffic it deactivates itself and will only stop a few times, perhaps 3 in row, consecutively. It says this in the manual and is certainly my experience.

The auto hold groans slightly but this is only the pads against the disc, and isn't your tremble as you have this autohold switched off.

Sorry can't assist, hope you get it sorted.

I activate the autohold in traffic where it is really useful. When turned on, brake to a halt and when the green icon lights up in the display take your foot off the brake. With the green icon lit up you know it is holding.

The stop/start, as I've done with previous cars, I turn off as soon as I start the car.

That's indeed what I've done as I feel lot more safe and comfort.
