Well this is brilliant
Just Phoned Mitsubishi after being told they would phone me back(still waiting)
It is a sensor in the exhaust and is on backorder
Can't tell me when I will get it BACK
Then offer a small car as a replacement
As indicated in post above , getting parts and even some cars is very hard at the moment due to Covid . In similar circumstances , when I had similar problem in different dealerships with a relatively small part like this on backorder , I have taken one of another new car in stock to get the customer back on the road again . Especially with such a new vehicle ( recently purchased) and low mileage . Good business to retain customer and keep happy .
