Hi,

I'm new to Volvo and new to this forum. We just purchased a new 2019 XC90 T6 Inscription and I have noticed while at a stop a slight bump almost like someone slightly hits you in the rear. The bump does not happen all the time, but it is annoying.

 

given your car is under warranty, did you ask the dealer to check it out? Does your car have the engine shut off feature while stopped at a light? If that is it, you should be able to have the dealer reprogram the feature settings.
