“My Buick purchased november 2019 has the misfortune of having the 2.0 ltg 4cyl turbo. Through research I have learned that catastrophic failure with the pistons is a common occurrence across the GM platform with same engines. This is likely caused by a misfire or preignition in the cylinder which which feeds on itself as it gets worse. Also the pcv system designed for a naturally aspirated engine not a turbo engine. This system functions only when there is no boost from the turbo. This cause gunk to build up eventually back flowing into #1. …”

“Off and on over the past 6 months, there was a loss of brakes directly after startup. After 30 seconds or so, the brakes would function normally. This car is normally garage kept. Walking to the car at night to leave, I noticed oil on the garage floor coming from under the car. After opening the hood, I noticed oil in the engine compartment coming from the top of the engine. After removing the plastic engine cover, I saw that the oil was coming from what I learned is the vaccum pump. There was a visible break in the pump housing. …”
