Consumer Description
Engine exhaust makes vibrating noise similar to a leaf blower under acceleration. TSB issued due to common issue and GM refuses to recall or fix. Broken baffle/weld inside of front muffler/resonator on exhaust system under front passenger compartment. Issue getting worse. $2500 at local dealership to fix, with GM offering “assistance” to fix issue in the amount of $742 leaving the consumer with balance. At what point will the rest of the defective part deteriorate and cause clogging issues and more damage?
