Buy a Toyota or a Nissan! Seriously though, you describe a rattle while stopped with engine under strain. Some places to look: catalytic converter shield. Thin sheet metal that's over converter as a heat shield. Notorious for rusting and rattling. ALSO- check other parts of the exhuast...clamps, hangers... If you decide to stick your head under the car to find out, make sure each wheel has a chock, front and back, and the emergency brake is on! Good Luck! <<<ADR>>>

A loud rattling noise when the air conditioner is on in a 2001 Acura MDX could be caused by several issues. Possible culprits include a loose or damaged compressor, foreign objects caught in the fan, or worn-out or failing components like the blower motor or pulley. Additionally, issues with the AC system’s mounting brackets or ductwork could also lead to rattling sounds. It's advisable to have a professional inspect the system to diagnose and address the problem.
To eliminate the rattling noise in the rear hatch of a 2001 Pathfinder, first, check for loose or damaged components, such as the hatch struts, hinges, and bolts. Tighten any loose screws or bolts and inspect the weather stripping for wear; replacing it can help dampen noise. Additionally, try adding foam tape or rubber washers to areas where metal contacts metal, as this can reduce vibrations. If the issue persists, consider consulting a mechanic for further inspection.
