Description of the problem	My hyundai sonata began increasingly consuming oil rapidly for a couple months until it got to me putting in 1 quart every 200 miles!!! That destroyed the catalytic converter, although the tech at the dealer tried to tell me it was due to fuel. Experts at both the exhaust shop and ford dealership (where i bought it used), refuted that and told me it was definitely due primarily from the engine consuming way too much oil. Hyundai required me to do 5 oil consumption tests at their delaership before they can verify and document the engine is having problems! But in the meantime my engine could likely blow up/seize up, as the 2011 hyundai sonata is notorious for that and they recalled 470,000+ already!! I only have 3 oil consumption tests, and it shows 200 miles per quart!! My cat converter is now clogged and my car lost power. So now in a catch 22 (maybe on purpose?). I can't get 5 tests without replacing my catalytic converter, but since engine is losing 1 quart per 200 miles that oil will soon destroy any new converter i put on within 1 or 2 months, if not less!! So this is ruining the car, and i have started a case number with corporate hyundai in california. They haven't called me back in several days all the while i don't have a car to use. Engine burning 1 quart per 200 miles or less is terrible.... Engine is ruined! And it's not safe!! As i have read so many 2011 sonata owners telling about their car engines seizing up, locking up while driving 65 mph on the highway in the middle lane!! I hope hyundai takes responsibility as i still owe $9,000 on this car!

What is Recall?
A recall is when a product is removed from the market or a correction is made to the product because it is either defective or potentially harmful.
What is Failure?
Failure is the state or condition of not meeting a desirable or intended objective, and may be viewed as the opposite of success. Product failure ranges from failure to sell the product to fracture of the product, in the worst cases leading to personal injury, the province of forensic engineering.
