Cracked valve cover first occurrence was August of 2017. This was replaced under warranty. Second occurrence happened January 6,2019. This occurrence caused multiple failures and cost me $727 to have repaired. Symptoms were noticeable off shift points due to lack of power and too much air to turbo. Also a surviving of the engine when going up steep hills. This is a known issue as both times the dealer knew what the problem was and had parts on hand to fix. I took video of both times for my records.

The Buick Encore has 15,000 miles on it, the last 2,000 miles or so the engine hesitates any speeds. It does not stall but it keeps hesitating. The car has been taken to the dealership twice, the problem has not been fixed
