The 3.6 liter engine in my 2018 Buick Lacrosse Avenir only has 53,939 when we experienced a thermostat failure. The engine temperature was dead cold, and the dual electric fans were running non-stop. When I scanned the trouble code, I found PO128 which points to a faulty thermostat. Because the thermostat is buried under the intake manifold, we had the local Buick dealership replace it at a cost of over $800.00. I don't feel that a car with so few miles should be experiencing a thermostat f

I have brought my 2018 Buick Lacrosse to two different Buick dealerships who say that even though a special instruction letter was recognized and a recall was observed, because my check light went out and the codes on the car where cleared, they will not fix either recall. On three different occasions, the car slowed down to a crawl speed, the check engine light went on and the brakes applied themselves. Also across the dash was displayed 'service transmission'.
