Yesterday, I picked up my Chevrolet Trax ls from the agency and, on my way home, I noticed that the engine made a lot of noise when accelerating. But that was not all. When stopping at a stop sign, the van started vibrating, and the vibration was felt from the steering wheel to the rear seats and even the doors. I noticed that, when braking, the vibration got even higher. I really do not know which the failure might be, but I am absolutely disappointed because it is a new car. Today, I am taking it to the agency, but this kind of failures should not appear in vehicles that have been just taken out of the agency.
