Which heat shield? There are several.
Driving without a heat shield may damage the car. It can damage the car by melting any gaskets (rubber hoses), and electrical wires close to it.
There are several most found near exhaust manifolds & around muffler pipes & parts like the catalytic converter has heat shield above it
usually a loose heat shield or a muffler rusting out, exhaust parts rust from inside out. My money is on a loose heat shield
Heat shields are used on cars to protect components and bodywork from heat damage coming from the engine and exhaust system.
Loose heat shield... Not a big deal at the beginning untill it gets really unoying later... Best way to fix it by removing the heat shield or replace it with a new one
Possibly a loose heat shield or other component.
