My first, a 91 Dynasty with 3.3L engine, caused me no problems at all for the three year I had it except that the belt would squeak. Hit a deer with 210,000 miles and totaled it. Second one, a 93 Dynasty, however has had a few problems. Like mentioned before, in cold weather the doors don't want to close. I had to remove the stiff grease from inside the door mechanisms and replace it with a graphite lubricate to fix. It also has the 3.3L engine and the belt squeaks on it too. Have tried 3 different belts. Fuel economy not what it should be. The 91 got about 25mpg, the 93 about 16mpg. Same engine .. still trying to figure it out.
