Engine oil leak detected in 2021 @33,195 miles caused by broken aluminum bolts in upper part of timing cover. Repaired by dealer on a “good will” basis for what I was told would have cost me approximately $9-10,000. Oil leak reappeared in 2023 @44,657 miles (less than 12,000 since first leak) caused again by broken aluminum bolts in the lower, upper oil pan, and timing cover. Repair done this time by independent shop at a cost of $6,865.70.
