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.

When slowing almost to a stop, and then need to accelerate, such as slowing for a yield sign, then trying to merge, vehicle is non responsive to throttle input for at least a second, or more. This has put me and others at risk because I assume I'm going to be able to accelerate when pull into traffic and am not able to. The dealer has had the vehicle but was unable to reproduce. It does not always do it, there's some combination of engine, drivetrain or fuel management it's in that does this. I have disabled start/stop mode. There are no system messages or OBD errors. The dealer has said that others have experienced this and the manufacturer has told them it's "normal". It's a safety problem and I'm seeking help in getting the manufacturer to fix it. Note, I sent the attached letter to manufacturer and did not receive a reply. I called their customer support line around Sept 20th and they did not offer any escalation or other action to address other than writing to their email address. I did this, and received no response.
