2023 plug in hybrid XC90. These alerts have been coming up for a month every time in reverse. I’ve cleaned the sensors/rear camera a couple of times, had it professionally car washed, there are no cracks/dents/imperfections I can see on sensors/camera but still the warnings persist and reduced functionality in reverse - no warning beeps/coloured bars on 360 camera. It’s having its annual service at Volvo in a couple months but before it costs me loads to take bumper off and fix anyone had this issue before? Thanks
