What is your question?

It's had a tuneup recently . We were told that was it. Still rattles when you accelerate especially goong up hill

What makes this problem better or worse?

Guess worse once you driving it. It can be a small incline and it rattles

How long has your 2018 Jeep Grand Cherokee had this problem?

Several months
