Well last week my 2021 60 day old van tripped a nOx Upstream Sensor, in normal times this would have been a trip to the dealer for a simple warranty fix. NOT now... Sensors are on Backorder Worldwide with NO eta for when they will be able to fix the Van. So my brand new van now sits at the dealer awaiting a part along with a bunch of others.... I hope this gets resolved soon. MBUSA will need to address soon!
