2021 ram 1500, 5.7 ETORQUE, 45k miles. In the last 5 months I’ve noticed a metallic tapping or ticking noise from driver side. Louder on cold starts, can still hear it at operating temp. Very noticeable in MDS mode and sometimes under load. I have also had some bucking and what feels like a loss of power around 60mph. No check engine light. I had both manifolds replaced at 30k miles. This video is at operating temp. Dealer says it’s just a rattling heat shield. Take very good care of the truck, oil and filter change every 4k miles. https://youtube.com/shorts/qVEDoY2zbHk?si=H4TuDbvY21SjCu3d
