The car was in motion at approximately 40mph when the oil light on the dash illuminated. The engine then shut off, causing a loss of power and absence of braking assist, which made the car very difficult to stop. The car did start again, but made a loud banging/clunking noise. I drove it the next day and it did the same thing again, and the clunking became louder. It appears to have spun a bearing judging from the loss of oil pressure and the noise (oil level checks out fine). This could have caused a serious accident if it had happened on busy roadway like the one that I travel to and from work. This occurred with approximately 115,300 miles on the odometer. I had the recall 132 inspection done on this car at 110,485 miles, and it passed at that time. Please note that this dangerous failure is still happening after the recall inspection is performed. The inspection procedure may not be sufficient to diagnose this issue.

I was driving on the highway and as soon as I got off I heard a knocking noise coming from the engine so I looked it up on the internet and it said their is a recall on the engine for that very problem

- St.Peters, MO, USA

2011 Hyundai Sonata limited 2.4L. Vehicle has been eating through 2 quarts of synthetic valvoline 5W20 oil every couple weeks. The dipstick always has black tar like oil on the tip. There's no leaks underneath as I keep a piece of card board under it while parked. I began noticing this at around 82,000 miles because when getting it changed around every 2500 miles, the mechanic always stating, "your really low on oil." So, now I check my oil every other day.. the engine has been making a loud knocking sound for over a year now. And, the check engine light came on at around 112,000 miles. I just had the engine recall test done at the dealership in terre haute, in. They stated it passed the inspection test and still couldn't tell me why it goes through so much oil or why it's knocking so loud. Also, the check engine light is still on.. and, now I'm at 140,000 miles. Also, I've had to replace the starter selonoid lever 4 times now! it's a cheap 8 dollar plastic part that keeps breaking inside the starter. And, will pass the starter test if U take it in. Left me stranded each time. Dealer wanted $800 to fix plus tow fee.. I did the job myself instead.

I was on the highway about 25 miles into my drive home from work started hearing a faint noise kind of like an exhaust leak. Within 2 miles it was getting louder so I started thinking my exhaust was disconnected or something. I get out of the car and see just a little smoke from the hood. Within a minute I noticed there was more smoke so I looked at the front grill and saw small flames. Called 911 but took them over 10 minutes to get there so car was completely destroyed. Car had 98500 miles and showed no signs on any issues. I had all the recalls done and Hyundai passed the car for a recall that caused engine issues and fires. Hyundai has an open investation and I am working with them. From what I can tell they have a major issue and most of these cars have the issue right around the 100K mark. I feel this just might keep happening and Hyundai really should do something more to fix this issue.

A catastrophic engine failure occurred on the freeway while driving at 70-80 mph. The first warning was sudden engine noise, a loud ticking or knocking sound. This was shortly followed by the oil light illuminating, then the engine light, and then engine seizure (RPM dropped to 0). As I was pulling to the side, smoke began billowing through the vents. Upon exiting the vehicle I realized the engine was on fire. The vehicle was well maintained with no prior warning. The fire was put out with gatorade from an observer who pulled over.

My car use too much oil, every week I have to add a quart in a half of oil, that is becoming extremely pricey for me and getting oil changes is worthless to me because it like I'm wasting money by getting them. It would also help to have a low oil warning light show up because before I noticed this problem with my car I was very low on oil getting off the highway that god I was only blocks away from a auto part store to by some motor oil...this really do suck

This vehicle is burning a qt of oil every 500 miles! I have had the engine recall done with no issues but oil is still disappearing. There are no puddles nor any on the outside of the engine. There are numerous complaints about this same issue and after all the recalls and repairs I've dumped into this car, I wish I hadn't bought it.

- New Richmond, OH, USA

I experienced a total engine loss in 2015 while travelling on an interstate highway in my 2011 Hyundai Sonata. My mechanic diagnosed it as an engine debris problem. This was prior to Hyundai disclosing that it had a known engine debris flaw with the engine. Rather than scrapping a four-year old vehicle, I had the engine replaced because the rest of the vehicle was in good shape. At the time of replacement new 2011 Sonata theta II engines were impossible to obtain (because of the high failure rate) so a low mileage (53K) used theta II engine from a different 2011 Sonata was obtained by my mechanic and installed in my vehicle. Obviously, this occurred before it became public knowledge that the Alabama manufactured theta II engine had inherent and dangerous flaws. Tragically but predictably the new engine is now exhibiting the same symptoms as the old one. Upon inspection the engine was diagnosed by my Hyundai dealership as having failed the campaign 132 diagnostic test. Hyundai has however repeatedly refused to provide any remedy to this second engine problem, saying that they don't want to provide remedy because the engine was sourced from a different 2011 Sonata (and that the engine is not the original one). It is unconscionable to deny compensation because I had the unfortunate experience of being the recipient of not one, but two engines that failed due to the same faulty design flaw. Hyundai should stand behind its faulty product and provide a remedy to the problem of their making.

The manufacturer was contacted and provided case number: 10640136. The failure mileage was approximately 112,943.

My engine is knocking and consuming oil. It worsens with increased RPM. Something sounds wrong in the engine and it has a high oil consumption rate yet there is no evidence of oil leak under vehicle. The dealer does all service, its under warranty and yet they have not taken care of the problem though they have been notified of this issue several times and inspected the vehicle. I am afraid I will have a total engine failure and put my safety at risk either from a crash or being stranded in a deserted area.....also Hyundai charged me last year to replace a coupling in the steering which was causing the issue and yet there has been a recall on this coupling. Bentley Hyundai of huntsville, al. They keep charging me money for repairs or inspections that should be covered under warranty.....please help!

- Huntsville, AL, USA

Vehicle is making a loud clicking sound in the steering column and while turning either left or right its a double clicking loud sound. While the vehicle is at a still position when you turn the wheel you can hear a clicking noise both right or left. If you hit a bump you can hear a loud annoying sound like something is loose. It gets louder and louder. You can hear it over the radio. This happens either on streets and the interstate aka highway

- Dunbar, WV, USA

After starting the car on the street I pulled the car into the driveway to wash it. After about an hour, I tried to start the car to move it out of the driveway. It would no longer start. Turns out the starter had burned out. Took the car to the shop. They stated that the even after replacing the starter, the starter continues to try to start the car while the car is running. This will cause the starter to burn out. I have had to replace the starter with 69K miles on the car and now have been warned that there is an electrical problem that will burnout the new starter unless I get it fixed.
