Engine has gone out twice within 54k miles. Service tech said this is a know issue with the 2015 Buick Regal engine. I just had it replaced the 2nd time in Feb of 2020. First time it went out there was only 12k miles on it. Now its Nov. Of 2020 and the car is having the same exact issues as it was when both engines went out. I cannot believe this is happening a third time. This is not fair as a consumer to purchase a new car with barely any mileage and the engine keeps going on. I was on the freeway the last time. Worst possible timing ever. This is like a never ending really expensive issue.
