MILEAGE AROUND 82,000 MILES | ALWAYS HAD ROUTINE, ON TIME, MAINTENANCE | NO ENGINE LIGHT ON (OR ANY OTHERS) | ON A TRIP DRIVING DOWN THE HIGHWAY GOING AROUND 65MPH WITH CRUISE CONTROL SET (2 ADULTS AND 1 CHILD IN THE CAR, NOT TOWING ANYTHING), OUR SUV STARTED MAKING A STRANGE NOISE WHEN ACCELERATING, THEN PROGRESSED TO A CONSISTENT NOISE WHETHER ACCELERATING OR NOT.
