Ford Fusion 2006 50000 miles
When braking my car, an engine sound appears, it starts vibrating and it seems as it were about to stall. When it is already warm and I am driving along an uphill road, it loses strength and it stalls. Even more, it is not braking properly. Brakes and brake pads have been checked and they are alright. Could you please tell me what it might be? Thanks.
