2011 Hyundai Sonata gls automatic transmission. Problem with ignition key. The key will not go past acc to the lock position to allow the key to be removed. Followed directions in manual to push the key in at acc position, but the lock mechanism does not move. Happens every other day. Have restart the car and move it and try the process again to get key to move into its proper position (lock) to remove key. Impossible security situation as cannot leave key in vehicle. Also stability control light comes on every morning., and car stalls every time I make a turn while driving. This is dangerous. Took my vehicle in to the dealership who claimed that all recall and campaign situations had been resolved with my vehicle.

In November 2018, we had a rattling noise during low speeds, which turned out to be a problem with the engine (engine seized up during warm up inspection by mechanic). The engine was replaced for free due to an extended warranty that was part of a recall and settlement agreement with Hyundai. In February 2019, the check engine light came on, which was for a damaged catalytic converter and cost over $2000 to replace. Last month, we received a recall notice from Hyundai stating " Hyundai is conducting a safety recall in the United States to confirm the high pressure fuel pipe was properly connected by Hyundai dealers to the high-pressure fuel pump outlet when the engine was replaced under recalls 132 and 162. " we have an appointment scheduled for this service. There is a new recall for other Kia and Hyundai models that include the catalytic converter, but it has not been included for our model year.

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!

I was driving about 55 mph on a highway and my car just shut down in the middle of traffic and wouldn't start, I was blessed not to get from behind. I had to have it towed home. Now I'm afraid to drive it. Also my steering wheel has been making this rattling/knocking sound anytime I try to steer it at all times. I have call in every recall notice I've gotten and I'm always told my car wasn't in the recall.
