Agree with Poor Richard and BroadHopper.
Find someone who can actually diagnose issue.
Not a new car dealer that wants to replace parts until they find issue.
Below is a Utube video of a mechanic/garage that actually does diagnosis.
This video is not about your specific case. This is a video about how a mechanic does diagnosis.
Also shows how some manufacturers use inferior OEM factory parts - that wear out early.
