NHTSA Complaint #11559401 — 2024 MAZDA CX-90

First took the vehicle for unscheduled service around 2,000 miles relating to engine noises, primarily rattling while driving. It's sporadic, but it sounds as if something was rattling underneath the car, primarily when accelerating, most noticeable when ramping up from slower speeds/lower gears. Also, when switching from drive into park, the engine makes unusual rumbling/rattling noises before settling into the regular engine idle rhythm. Finally, at 2,532 miles, the check-engine light came on, along with the message "Engine Malfunction. Have the Vehicle Inspected".
