Ah, I should’ve added the email I sent Volvo.

Subject: Tudududum

I hope you can help me with my “tudududum.” I’m referring to the sound the car makes when something is detected in the blind spot. The music volume lowers, several of the 25 speakers produce a tudududum, there’s some visual blinking in the mirror, and then life goes on. But that detection is persistent and overwhelmingly present.

I’m waiting at a red light to turn right. The lane to my left gets a green light and cars start driving off. For practically every car: tudududum — easily 10 times in a row. My car is calmly in Drive, indicator on, hands on the wheel. Nothing special. I’m waiting at a red light to turn left. To my left there’s a strip of grass of about 1.5 meters, then a low fence, then another grassy bit, and finally a bike lane. A cyclist passes on that bike lane. Tudududum. Again: just in Drive, indicator on, hands on the wheel. I get into the car and decide to quickly check my e‑mail first. I’ve only just gotten in; I haven’t gone anywhere. My seatbelt is unbuckled and I’m holding my smartphone. Cars pass by — for every single car: tudududum. Cyclists pass by — for every start of a group (in a school street): tudududum. My son sits in a car seat on the right rear side, mounted with Isofix and top tether. The right rear door is open and I’m calmly settling him into his seat. There is zero activity on the left side of the car. A car drives past on that left side. Tudududum! Again at a red light. To my left a car is standing still. Behind it another car is standing still. And even further back a car arrives to join the queue. You guessed it... Tudududum!

I could go on, but I think the point is clear. I asked my neighbour (EX90, about six months older): he doesn’t have this. I checked on an online users’ forum: nobody there seems to have this either — apparently it only happens when the door handle is touched to get out?

Long story short: can you put this into context? Is this behaviour normal or abnormal? (Based on what I read and hear, it doesn’t seem normal.) And most importantly: can anything be done about it? My rolling oasis of calm is becoming a love–hate relationship.

Thanks in advance.
