- Westport, CT, USA

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

The contact owns a 2011 Hyundai Sonata. While the contact's daughter was driving 20 mph, the vehicle sputtered, made a knocking noise, and lost power. There were no warning indicators illuminated. The contact stated that the vehicle was towed to southern states Subaru of raleigh (2511 wake forest rd, raleigh, nc 27608 (888) 439-5154) where it was diagnosed with a faulty engine that needed replacement.

The manufacturer was made aware of the failure and reffered the contact to Hyundai awards to repair the vehicle. The contact stated that the manufacturer inquired of an estimate of the repairs. Without an estimate, the contact quoated $500. The vehicle was then taken to johnson Hyundai of cary (5000 old raleigh rd, cary, nc 27511(919) 439-2059) where it was diagnosed with a steering coupler and axle failure.

- Coats, NC, USA

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.

- Houston, TX, USA

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.

- Margate, FL, USA

Took car to dealership for engine recall check in 2016, was told my car was fine only to have the engine seize 12 months later while driving. Engine was replaced by northtowne Hyundai in kc, mo and car was returned after 7 weeks. Within a few days of driving with the new engine I heard a distinct whining at about 2500 RPM and noticed a steady leak due to spots on my driveway. I returned the car to the dealership who said that the leak was from the transmission and that they have no liability since the engine replacement did not cause them to have to actually touch the transmission since the two systems are completely independent of one another. Corporate Hyundai says that the powertrain (I.e. transmission) is not covered under their extended 120,000 mile warranty and the cost of the repair is going to be an out of pocket expense to me.

- East Lansing, MI, USA

I was driving my car about 45 miles per hour. All of a sudden my engine just cut out. I began to pump the gas and there was no acceleration and no sound from the engine. It was completely dead. The lights were on and all other functions were working properly. The yellow engine light came on. I had to pull over and was hoping and praying that my brakes were still working. They did. There was no warming. No oil lights or coolant lights came on. It was about 75 degrees and a clear night with no rain. I have taken my engine in 2 other times due to weird sounds and odd issues for the recall. All time it has passed the "pressure test". my car was towed into the dealer. They are admitting there is definite noise in the engine, but it is still passing this random test. I have had all my oil changes and am at the dealer enough that they know who I am. This could have killed me if I was on the freeway here in southern California. My dealer has been amazing. The corporation is giving me the run around. (please let me know if you need my dealer print out to show that it is in for service)

- Long Beach, CA, USA

Engine failure while driving in middle of road without any warning. When attempting to restart vehicle smoked and smelled of electrical burning. Hyundai service center originally said this vehicle was not part of the 2011 Hyundai Sonata theta II engine recall, but when advising I found online (specifically at autoservice.hyundaiusa.com) that it indeed was, they agreed to check vehicle and contact Hyundai to have added to the recall. This vehicle exhibits all the problems mentioned in the recall/lawsuit. They occurred suddenly and without notice. We were at risk of crashing or being hit by a vehicle due to manner in which it broke down. Vehicle was at risk of fire, as it smelled of burning and smoked.vehicle was left at service center and am awaiting response.

I never received the notice on my car recall number 123. I have taken my car in for all recalls I have received and I was never told that the engine could fail because of metallic debris wasn't removed from the crankshaft. My car is in the shop because the motor is locked. It just stopped and then would not move. Southern states Hyundai in raleigh is where I have taken my car for all recalls for four years. They knew about this defect in 1915, but have never informed me or done the work required by the recall. My car was made in Alabama and the Hyundai web site confirms that my car should have been covered under this recall. Southern states is saying they have no recall for my car but one small thing that needs to be done. They don't want to fix my car even though it is there fault that the recall work has never been done.
