Check engine light come on during a road trip. Took to a mecanic who couldn't find the exact problem, took it to Buick and they knew right away what it was. $2200 quote. FML! Carb build up on cylinder 6 and valves.

You have to have the engine chemically cleaned, run premium fuel and use a cleaning agent (sea foam) every time you fill up. If I had known all the extra expense I never would have bought this car. The engine light comes on all the time and when it flashes you are supposed to pull over and shut it down. If you don't raw fuel dumps into the catalytic converter and can melt it. I received all this info from a mechanic. It's not Buick but GM! AGAIN!!

If anyone knows what I'm talking about PLEASE e-mail me. I have 4 more years of payments on this car. It seems to me there should have been a recall on this series of engines GM knowingly put into distribution. Please , if anyone knows anything about this, let me know. I do not know what recourse I have but to deal with it. I am going to keep looking into it though.
