My car broke down on a busy highway during a lunch rush due to an engine rod knocking in the engine. It was a terrifying experience and even sitting still on the side of the road I was scared my car would be hit by any of the 70-80mph cars exiting the ramp behind me. I tried joining the class action suit but for some reason, even though it's the same engine with the same problem, hybrids aren't a part of the suit.

My car stalls, lags and shuts off while driving and has a strong scent of exhaust and uses an awful amount of oil but there are no visible oil leaks. There are no check engine lights on. I have taken it to the muffler shop who states no exhaust leaks are found. My local gateway and mike morgan hyuandi says it throws no codes when put on the diagnostic machine so I cant find out the issue. From research I see this is a common issue with this model cars and I feel this should be looked into because it is a hazard especially when it kills in the midst of traffic

For an unknown reason my 2012 Sonata loses power at random causing us to have to pull over or it powers back up and it will continue. This is extremely dangerous and we have taken it to the dealer and it keeps happening. Life threatening.

I was driving down the street at approximately 25 mph when the car said "hybrid system failure." I pulled over as I noticed the car wouldn't switch to the gas engine as I went up the hill. I pulled over and noticed the hybrid battery level was going down and not switching to the gas engine. I called for a tow and had the car towed to the Hyundai dealership. They informed us that the engine was shot and had to be replaced for $6,500 and that engine would have no warranty on it. I asked if it was the same issue as the 2013 Sonata that we own that did the same behavior. The answer was yes it is similar, but the hybrid is not covered by the recall. I find it weird that both cars have the same engine with the same issue, but the hybrids were not recalled.

While driving on a busy interstate at speed (approx 65mph) on 9/26/20, the engine abruptly shut down. There was no warning, the vehicle was traveling straight. The vehicle was taken to the only Hyundai dealership in the area and inspected/ diagnosed 9/29/20. The dealer stated that the engine had seized and must be replaced. The estimated cost to replace (with a used engine with 40% more miles) was 25% higher than the replacement value for the vehicle. The dealer representative said the vehicle was not covered by safety recall 15V-568 relating to 2012 Hyundai Sonata's with the 2.4L engine. The recall does not reference any specific model and only discusses the failure of the engine which is common across hybrid and non-hybrid models. The vehicle has only 78,000 miles at the time of the engine failure. Engines should not fail this early, unless there is a manufacturing defect. Which it seems there is a very well known defect to this very engine that results in this very outcome. Except for some unknown reason the known failure with the same engine in a hybrid model is not covered by the recall.

I had a recall done on my Hyundai Sonata 2012 for the fuel pipe. I took it in to the Hyundai dealership in richland hills about a year ago, before covid19 I believe because I don't recall wearing a mask. They were extremely rude to me at the Hyundai dealership so I left there without knowing if there was a problem or not with my car. Now a few months ago I received another recall for the same issue an they said my fuel pipe needs to be replaced but aren't honoring the recall and are saying I must pay for the fuel pipe myself.

Hybrid system warning, shut off don't drive!!! light came on car shut down while in reverse, it was fine in drive! took it to the Hyundai in mesquite tx where I've had numerous issues in the past but had to go somewhere close! they couldn't find a diagnosis went through all the codes, said it wasn't shutting down for them and it was an oil pump and oil assembly $1,904.49 minus the $150 diagnostic to not even tell me why it shuts down in reverse giving a whole other issue with the car that isn't a part of the reason I took it in! never again will I buy a Hyundai!

So many issues my cars had...1 owner and several issues sadly could only pick 3: seat belt won't click on driver side sometimes it gets stuck, had the steering buttons fixed due to getting stuck, front passenger wheel has been checked several times due to the wheel vibrating when you hit a bump, hybrid battery went bad before 50,000, reading all the engine issues around 160, I'm thinking I need to back away from Hyundai forever!!! most recent hybrid warning do not drive & after researching there's been several issues with this, I'm thinking we could start a small class action suit against Hyundai!!!! car shut down and wouldn't go anywhere

Bought this car from a private seller. 2 days later driving 80mph on a 4 lane freeway the car loses all power and stops. I limp car off busy freeway (mind you with an Arizona hwy patrol officer in the median didn't ask me if I needed help). Found out that my engine block had metal in that was left in it when the engines were made in Alabama. Hyundai knew about this issue and told the NHTSA that they didn't feel it was a safety issue" not a safety issue to lose power at 80mph??? [xxx]? take it to the dealership jim click Mazda/Hyundai tucson AZ and they have it back to me in 2 days? a new engine block with all the old parts put on it? [xxx]??? car is making a noise when I pick it up that it wasn't making before the engine went out. I call the dealership say hey car's making a funny noise when I accelerate kinda like it was before the motor went out. Which by the way was under safety recall.so today I am diving and lose all my ac no ac it's 110 degrees outside I call a friend to look at it he pops the hood and right away notices 2 bolts/brackets that hold the ac high pressure line to the car missing! wait bolts are missing??? yes when the dealership put the car back together they forgot to bolt the thing down?? I tell my service advisor at Hyundai about it and show him when I get the car there. Like ummm hello???? where are these bolts. He downplays it and acts like I am stupid. It's their fault. So then he calls me to tell me the issue is the cooloing fan and resisitor for the engine. The wires are melted!!! [xxx] again?? like are U serious" I feel like they did a [xxx] job to begin with putting the new engine block in and probably the same guy who didn't put the bolts in is most likely responsible for the issue with the cooling fan!!!! parts of this document have been redacted to protect personally identifiable information pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

My Hyundai Sonata 2012 recently experienced engine seizure on a 5 lane highway in NJ garden state parkway at 70 mph without any warning what so ever.car was checked for this recall year ago and supposedly software was installed to notify if engine was to fail. There was no warning! dealer confirmed the engine died and is covered under the recall. I also had mentioned concern about the noise under the car. They replaced the engine & serpentine belt and told me to come back in 3 days as it was too early to do the inspection. When I got the car back the noise was still under the car, the tire light came on, back door lock stopped working and ac stopped working I called back and they told me $1500 worth of work to pass inspection. 3 days earlier they said the car was good to pass. Including Continental tires that Hyundai horrible suspension ruined at 16K miles(tire warranty 70K miles) and both sway bars and sway bar link. Which means I could have rolled the car at any curve.axles were changed twice on this car as they told me " manufactory faulty" axles they put on and other suspension parts. Tires were rotated and aligned by them! if that's not good enough person working on my car damaged both of my front doors when letting the car off the lift.then the dealer tried to cover up the damage and sign me the car back! car has some serious electrical issues with interior/exterior. Lights melting, bulbs burning and now the car doors locks. Better yet new recall says if you had your engine replaced you are in a danger of the fire.how am I supposed to trust this "certified dealer" ? + the other 8 recalls and class actions about this car- Hyundai needs to be forced to buy back these all of these cars. Not only is that not safe for me its also not safe for other drivers! I've also been without my car for about a month at this point.

The airbag light ha been on in my car for about 3-4 weeks and stays on continuously, will not go out. I have tried to have it reset, but it does not help. I believe this is or should be a recall because I have been reading over the internet and several other owners of this make and year model of Hyundai are also having these same issues. Also, there appears to be oil leakage but we cannot see it. We have to add oil to the car every week, even after we have had an oil change the week prior. I took it to Hyundai of bowie with these same issues several months ago, but they said there was no recall and before they could check it out, there would be a bill. I did not have the money and believe there is something wrong with the engine and may be part of the recall.

Car has been experiencing clunking noise since 2018. Vehicle would stall all of a sudden. Dealership checked it out and they failed to find anything wrong. On 6/23 I was on the fast lane of the freeway and car stalled and engine light was continuously blinking on and off. Cyclic knocking noise, RPM would not elevate from 1 car just stalled while in motion I almost got hit by other vehicles. Was able to pull car to the side. While engine light continued blinking. Going up hill it lost power as well. I was driving vehicle with my grandkids in the back seat. I feared for all of our lives. Sending pictures and I have a video as well.
