“During takeoff with moderate acceleration around 1500-2000 RPM there is an exhaust droning/buzzing sound forward of the front passenger area. Vehicle has been to dealer twice, the first time they replaced the entire exhaust system, but after 6 months the same sound returned. The second time they tried to loosen and retighten the exhaust but the sound returned immediately afterward. The droning sound is more likely to occur after exhaust is warmed up.”

We would like this to be covered or reimbursed.”
