Toyota Corolla Rattling Noise Repair Symptoms. A 'clunk' or 'knock' when turning, or when going over bumps, can indicate a problem with a ball joint. The sensation is often felt in the floorboard of a vehicle when driving. Worn front struts result in diminished ride quality that might feel “soft,” as the vehicle leans excessively during turns.

I have a 2015 Corolla LE with a 1.8L 4cyl engine and CVT trans. It is an order of magnitude louder than my 2003 Corolla when accelerating. The 2003 is relatively silent, like a luxury car. I admit I drive with a lead foot, and maybe most people wouldn't notice the 2015 acceleration noise that much. But it really bothers me. It sounds cheap and annoying. I'm pretty sure there is nothing 'wrong' with the car, that this is how the car was designed. But I'm pretty sure it is fake, and there is no way in buyer's remorse Hell that the engine should be this loud. Unfortunately I didn't notice when I was test driving, because I was too polite to floor it when the salesman was sitting in the car. How can I find out where the noise comes from exactly, and what can I do about it? Also, this car has a CVT, but it is acting like it has a very finite number of gears. That defeats the purpose of having a CVT, does it not? Is there anything I can do about these two issues?

OP, let's employ some logic. 1. Engine starts, no noise. 2. Engine revs, no noise. Ergo, it is not relevant to engine operation 3. Vehicle starts moving, noise is present. 4. For vehicle to move, trnsmission is engaged. Ergo, it is relevant to 2 new conditions, that were not present with vehicle NOT moving: - transmission operating - wheels spinning. As Corollas by far are not that mechanically complicated on power train, I am assuming several things: - transmission is producing vibration that is transferred into body, and metal is a great resonator - entire power train is vibrating, see above - exhaust system is see above - wheels or one wheel is see above. Try doing few things: 1. jackstanding front and spinning wheels, or even engaging D and let engine spin them 2. when coasting, place transmission into N and see what happens. I'd say, possibly one or several mounts are shot, allowing power train components touch the body and transfer vibration into it, hence you do not hear it from the outside, as it goes 'under' and 'into'. |
