2012 Lexus LS 460 - Odd metallic noise

Metallic noise coming from under car after being driven for about 10 to 15 minutes, and after going over bumps.

A mechanic can help better, but if it was my car, I’d get under it and inspect the ten-year-old exhaust from stem to stern. Looking for a rubbing part, broken weld, or a hanger that gave up the ghost. Mechanics put the car on the lift and then grab and shake the pipes. Be sure you do it cold or be very cautious. Hot exhaust plumbing can burn you.


Good post above. Very likely to be a problem with the exhaust system or the engine mounts. The exhaust system is attached to the engine, and if broken mounts allow the engine more movement, good chance something in the exhaust system will bang into something it shouldn’t. If this occurs more when accelerating or slowing, broken engine mounts definitely need to be considered.

Long sleeved shirt and gloves are your friends under there. Eye protection, too.


Heat shields too.
