I recently took my 2006 Infiniti QX56 in for an oil change at a local service center. The appointment went smoothly, and I expected to leave with my vehicle in top shape. However, shortly after driving away, I noticed a loud, unsettling noise coming from the muffler.
Concerned, I returned to the shop and informed them about the issue. The technicians examined the vehicle but claimed they couldn't determine what had caused the noise. This left me feeling frustrated and confused, as I hadn't experienced any problems with the muffler prior to the service. What should I do?
