NHTSA complaint #10980310, filed 2017-04, 48,000 miles“Went for inspection, shell cardinal forest, springfield, va. Inspection rejected due to faulty/worn out/dangerous motor mounts. Mechanic said design flaw. Lindsay Cadillac service manager admitted different design than other cadillacs. My wife and I, ages 55 and 70, have owned numerous vehicles, including 3 cadillacs, and have driven cars well over 100k miles, including far less expensive cars. Have never heard of motor mounts falling apart or even wearing out, especially not at 79k miles. Cheaper cars we've owned have never developed such a serious problem at that mileage. …”
