- Buick Ownership
I have a 2014 Buick Encore with 50600 miles. Car has been really nice thus far. Yesterday serious bucking as we drive, plumes of smoke from the rear, engine oil very low. I've added 3+ quarts in the last day. Car is burning oil. Car will have episodes of no acceleration on the road and then runs ok for 10 minutes and then bucking, smoke from the rear and then ok. Very very dangerous condition. I believe this car is still under warranty so I am hopeful the dealer will take care of it. Any tips or similar experiences?
