Early this year my granddaughter bought a new 2020 Nissan Sentra SV. When I went to change her oil, I could not see the oil filter or the oil pan; they were hidden under two splash shields that covered most of the bottom of the car. After a lot of research I learned how to change the oil. I had to remove six bolts and approximately 25 push pins in order to lower the back splash shield enough to access the filter and oil pan. Anyone who has worked with push pins knows that getting them out is a bit annoying but getting them back in can be a real pain. So what should have been a simple job became tedious and time consuming.
I had called the Nissan dealer before I did the job and asked if it would void the warranty if I cut a hole in the splash shield for the oil filter and another hole for the oil pan drain plug in order to make future oil changes easier. The service adviser said it would void the warranty because there are several sensors that are protected by the splash shield. Is this legitimate? (And even if it is legit, Nissan should have installed removable access panels for the oil filter and pan.)
