There are two issues with my 2018 Toyota Camry with 10,250 miles and under warranty. (1) one is a knocking sound that a Toyota dealer I took it to said is an engine problem and they have pulled the engine but they have not figured out what the problem is yet. This problem was missed when I took it to another Toyota dealer for the 10,000 oil change on July 30th, and expressed concern about a noise I thought could be a muffler noise. . This engine could have failed and only lucky for me it didn't while I was driving. This vehicle should be on the recall list for this engine problem and for the (2) transmission powertrain problem. When I pull out into major streets from a side street, I have to do it very gradually and cannot accelerate quickly because it will miss gears. This also could be dangerous when trying to pass other traffic on busy highways of one lane in each direction.
