Why my brake paddle is so hard?

[Vad13]

Everytime I go to start my telly, my brake paddle is so hard, I struggle to push it down so that I can start my engine.

Has someone noticed this or is it just me?

Here is another thread for the same issue. Doesn’t look like anybody has found a solution yet.

Won't start; brake pedal high and firm

Problem started 4 days ago. First thing after resting overnight; tried to start but brake pedal felt very high and hard. Car would not start. Not even a sound from the engine. Engine mobilizer light lit seeming to indicate that my key wasn't good. Used other key fob next day...same thing...

Maybe waiting a little while before trying again.

Also make sure once the engine is off, you are not releasing and stepping on the brake pedal once more. That could cause the pedal to become stiff.

Thanks, I think its my habit to keep pressing the break paddle after engine is off. I need to try releasing it as soon as engine turns off.

Or how about before? Put the car in park, release brake, turn off engine. 9 out of 10 dentists recommend that.

Even better idea put in park, apply parking brake, release brake pedal, then turn off.

The parking brake is going to automatically set when you turn the car off.

This is only true if you use Auto Hold at the time you park. Otherwise you need to manually engage the electronic parking brake.

My bad...learn something every day.

Update: issue is fixed by itself. Could be because of any of the following:

1- I heard on BMW forum that you should just turn on car, keep in neutral and apply brakes fully for 5-6 times in a row. I did this twice for couple of days. Apparently this helps rebuild the lost vacuum.

2- As other poster suggested: park, apply parking brake, release brake pedal, then turn off. Make habit out of this.

3- take your telly for 500m+ long road trip. Preferably to cold high elevation places. Like I did over last weekend.

I've had my '23 for 1w. In the morning on the first start the brake pedal is stiff. It becomes normal upon starting and works as expected on later starts. This looks like a loss of vacuum--perhaps due to a check valve. I have an service appt. scheduled for next Monday. I called Kia corporate--they'll reimburse me for a rental car.
