Consumer Description

Starting around 57,000 miles the engine started consuming excessive oil and occasionally experienced some knocking upon acceleration. I took it to the dealership and they put me on an oil consumption check every 1000 miles. After 3 rounds of checks they determined it was an issue with the GDI fuel system needing to be flushed which was performed by the dealership service department. The engine appeared to no longer consume excessive oil after I checked at about 1000 miles. After approximately 2000 miles, before my wife left for a long trip, I checked oil and it was down 1 quart. I topped off the oil and after about 750 miles, I checked the oil level and it was about 1 quart low again. The car is currently at the dealership and I'm told I will have to start the whole 1000 mile consumption check AGAIN! Based on other reports of engine seizing and fires I consider this a very possible hazard.
