Century LT 3.4L

  • Automatic transmission
  • 83,513 miles

This was the second GM vehicle I had with this issue. This time GM would not cover the cost of repair. Why I'd be dumb enough to ever purchase another GM product with DEXCOOL again is a good question, but I guess that is the definition of insanity; doing the same thing over again expecting a different result.

Century Custom 3.1L V6

  • Automatic transmission
  • 115,000 miles

I just purchased a 99 Buick Century Custom about a week ago. Went for an oil change yesterday and there is what appears to be oil mixed in with the coolant. I'll be taking it to be inspected today to see what the problem is.

Other problems it has - drivers side window doesn't go down sometimes. Passenger wiper stopped working. (Not the blade, it doesn't move at all)

Tires Plus claims it needs two outer tie rods.

The blower motor also sounds like it's totally shot.
