I have a 2023 XC40 dark B3P.
I have had a similar problem since day 1.
I would describe the noise as a "whooping" noise when I brake during regenerative braking.
I have recorded the noise and visited 2 main dealers who have not heard of a similar problem. They sent the recording to Volvo technical who said it was caused by the gearbox actuator which is a "characteristic" of the B3P.
I wouldn't except this as the dealer says its only my car that does it so Volvo won't authorise a repair.
Its embarrassing when passengers hear the noise and want to know what's wrong with it.
Customer services have been useless saying it is a feature of my car. (I don't remember ticking the extras box for a noisy brakes gearbox).
I can only see it getting worse before the car breaks.
This is my 2nd xc40 and 3rd Volvo.
I won't ever buy again.
Thanks for this gaughey.
I escalated this to a formal complaint to Volvo, I also sent a recording. After 11 weeks they responded saying that it a characteristic of the regenerative braking system on this model as you were told and they were not prepared to do any more. To be honest I have decided to accept it for now but like you have a niggling feeling that it could be leading to something else. At least knowing others have the same noise actually substantiates their assumption that it is a characteristic rather than a problem....hopefully!!
They also said they are working on a fix that may appear as a software update . How true this is I don't know.
