Customer Question

Hi George, I have a 2007 Buick Lucerne CSX, V8 North star engine. The engine alert came on a couple weeks ago that said: stop engine, A/C off. Happened twice. I stopped and sat a while, then slowly drove home. I now notice the needle moves toward the hot zone, but has never crossed over to the red. Took it to a Buick dealer, they said something about a cylinder bolt could be loose causing the gasket to overheat. Recommended I junk it or trade it in. I love this car. Have you ever experienced this problem?
