One problem related to loud engine noise has been reported for the 2005 Ford Escape Hybrid. The most recently reported issues are listed below.
I was about 115 miles into a 130 mile trip, doing 70 mph on the interstate, when out of no where my vehicle jerked very hard and then started making loud sounds like parts falling out. All of the cars behide me had to slam on breaks and avoid hitting me. No lights or warnings had come on until after this happened. I steered the car off of the interstate and down the ramp into a store parking lot. The car was not running hot. Looked under car and oil was coming out all over the ground. A man looked and said it looked like the coolant system messed up and it through a rod in the motor block. I got the car one month ago and it was doing great. By looking up on type car there is others having problems like this and recalls on the coolant system. But no one on my VIN. Recall 14v526000.
