NHTSA Complaint #11574558 — 2019 JEEP GRAND CHEROKEE

While at the dealer to have a lightbulb changed, I was told that I needed to have my oil adapter changed. My jeep only has 33,750 miles on it and has only been serviced by the jeep dealer. While I was there there were 2 other jeeps in with the same problem. Also, my brother-in-law's brother (who lives in another state) also had to have his oil adapter replaced on his jeep grand cherokee. Does jeep have a defective part installed in the grand cherokees? If not, I find it odd that so many people (that I do not know personally) have had to have the same part replaced on their jeep grand cherokees.
