Vehicle's engine is intermittently making noises again after exhaust manifold was fixed and also intermittently releasing carbon monoxide into the cabin of the vehicle. I have a video of the carbon monoxide reading, but the system will not allow me to upload.
July 2018 car began making noise when turning on and backing up. The noise went away when I began to drive. Took to dealership for oil change and they couldn't diagnosis the problem. Problem began getting worse, mentioned it at next oil change. Now mind you, I drive a lot!! car is 2 years old and has 83k. Between July and December 2018 the car received minimum of 4 oil changes all done at the same dealership who says it's normal even when I complained of smelling gas. After returning to va from mi, the lights on the dash all turned on while driving, speedometer jumped where ever it wanted if it wanted to move at all. Took to nearest dealership, diagnosis was bad vacuum pump. It was replaced and said all my driving issues and gas smell would stop. Nope. . . . Took back in, diagnosis is faulty exhaust manifold. Replaced. Two weeks later it starts to act up again like it did the first time.
