The 2012 Buick Regal consumes a quart or more of oil in less than 2 weeks or 300 miles. I am putting a quart in it just to get it to read on the dip stick and more if needed. As it consumes oil, the engine gains a noticable ticking noise with a rough start. All of this is noticed while driving on a highway or rural road. The back right tire and or tire area makes a thumping noise at all speeds. The tire is not the issue. The stabilitrak warning light comes on often . I am the 3rd owner to the car with with 164,333 current miles. The car has had routine oil changes etc by all owners.
Since I purchased and drove off from the dealership, within the first few days the car shut down on me when I was in a drive thru, and it happened times again while pulling out a parking space and drove a few feet away the car would shut off and began smelling of gas as well overtime I drove it. The dealership was not very helpful but finally kept my car a few days and said it was only the hoses which were loose. Now 4/24 my car again is making weird noises since last week and actually will not start this evening after being out and parking in a lot.
Vehicle turns off when going in reverse. Vehicle also makes weird sputtering noise when started. This has been happening since I bought the car brand new in 2011 but dealers can never replicate the problems!.
