New 2022 Volvo S60 began shutting off while driving on highways and Interstates and in once within feet of railroad crossing. Also occurrences of car being unable to turn off even after several attempts. Problem arose 2/2022. In all instances traffic, including 18 wheelers, was approaching behind at highway and interstate speeds up to 70mph. Sometimes a warning lamp would appear saying vehicle is shut off/ powering down, or place vehicle in park vehicle shutting off. Other warning lamps would come on like parking assist currently not available or park/brake needs service. Volvo Dealer that initiated repairs determined the mid voltage battery module was faulty and they replaced the MVBM and dead battery. And was causing the error messages that they too were able to reproduce. Car-€™s new battery completely drain in May but had not been driven for at least two weeks was towed to Volvo dealership which replaced battery. Days after car was returned the vehicle began stopping in the middle of interstates/highways and near railroad crossings again with same messages and was towed back to dealer, who this time said something was spilled on the center console (which is right next to the cup holder) so they say it is an external problem and they aren-€™t responsible for the failure and state that they can fix but can-€™t guarantee problem won-€™t mysteriously arise again. There was never a spill in vehicle. Additionally the pilot assist for the adaptive cruise control shuts off with no visual or auditory warning when sensors can-€™t read road markings. The vehicle has almost veered completely off the road and in two instances the beginning of bridges. No word from Volvo on problem when mentioned along with other safety incidents. I was traveling at 35mph during city instances and the interstate and highway speed limits during those occurrences and the same when adaptive cruise control pilot assist malfunctioned.
