When the object proximity sensors in the front or rear bumpers detect an object, the vehicle completely or severely limits the throttle. For instance, the rear bumper sensors detect the bike rack attached to my van and therefore limit the throttle response, regardless of transmission direction (forward or reverse). This seems to happen intermittently. When I mute the bumper sensor’s warning by tapping a button, then the throttle responds as expected. This is a known problem on the 2019+ VS30 Mercedes Sprinters, which affects all vans; it is not isolated to my specific van. This presents a safety issue, when the driver expects the vehicle to move but it does not. For instance, when rolling into traffic yet the throttle does not respond.
