Byers Subaru

Bought a used 2010 Audi A4 from them two weeks ago with 50k miles. Oil level low and oil pressure low light came on during the two hour trip home. Changed the oil the next day and it was black and gritty, as if it hadn't ever been changed. Car was burning oil very badly. Changed oil again after just 800 more miles because the car was still complaining about low oil and low oil pressure. Oil still came out black. After just 800 miles! Cleaned oil level sensor but car still kept throwing oil codes, as well as a new check engine light. Car was also placing itself in Engine Protection mode and would not rev beyond 4K RPMs. Car would also randomly shut off and need to be restarted. Waited another 1000 miles this time and changed oil for the third and final time hoping it would solve the problem. Nope. Oil still came out black and car was still throwing codes and breaking down. But now, a rod was knocking and the engine is ready to blow. Reported my problem to sales manager who asked "What do you expect me to do about it?" Yes, the car was sold "as is," but it should've never been sold this way. Shame on Byers for selling such a piece of junk and leaving it up to the buyer to mend the damages. They could at least offer a small 30 day 1k miles warranty like most dealerships do. Finally, I traded the car for much less than it was worth after traveling to several different dealerships because nobody wanted it because of the very loud and disturbing rod knock. Never buy anything from Byers without a warranty tagged onto your car. No wonder they bother you so much about getting an extended warranty.
