Hi All
I purchased a used 2016 highlander last weekend and over the week and a half I noticed that during idle and acceleration the v6 motor is producing very high levels of loud bass muffler sputter.. the dull loud kind with a "brrr". There isnt a metallic sound so it isn't the exhaust heat covers or anything.
I had my indie mechanic take a look with hoist and he couldnt tell anything on it running on idle...ie anything on the muffler. But I feel its distractingly and annoyingly loud inside the cabin with windows closed. There is no way that's normal. There are no lights on, and the car has a clean history on its 45k miles. Runs fine. Mileage is about 26mpg (9L/100).
Electric motor is whining a bit as well all the time which is also a significant but secondary concern I want to get to after the v6 engine and exhaust loudness.
Hoping someone can direct me to diagnosing both issues please.
Thx.
