Hyundai Motors fails to sympathize with their customers. I bought a Hyundai Sonata 2014 which caught a fire on October 9th 2019. Hyundai finally conversated me for the car in how much it was worth $4,150.60 on March 20th 2024 and not for punitive damages. I feel they are very unfair and I need my punitive damages I lost a lot not only a car but my job as well. My livelihood and transportation on top of that. And I need help to recover my punitive damages.

On Feb 15th 2023 my daughter was driving my 2014 Hyundai Sonata at the posted speed limit of 55 MPH on a 2 lane blacktop when the car suddenly and without any warning at all, lost all power and became unresponsive while traveling with other vehicles behind her, in front of her and in the opposing lane of travel. Without enough of an improved shoulder to pull to the right and a steep embankment on that side of the roadway as well, she was forced to veer to the left with other cars approaching. She had minimal braking, steering and no response to depressing the accelerator pedal at all. She was able to direct the car onto a paved portion of a feeder road and finally got the car stopped. The cabin filled with smoke and there was smoke all around the car but no fire was ever found. These vehicles are dangerous to the public and have a known engine defect that because of this the manufacturer has implemented a software patch known as KSDS and with this recall in place should have allowed my daughter to reach a safer place than being stranding on the side of a busy hi-way. My car had this patch installed and I was assured that this recall would allow the car to be driven a safe distance and it would be obvious when this patch was active and the engine would be put in "Limp mode" This did not happen, the engine locked

This is the 3rd time in 2 years my car shuts down while driving. The dash panel started flashing "WARNING CHECK CHARGING SYSTEM. DO NOT DRIVE" and an alert starts beeping and the car shuts off. THERE WAS NO OTHER PRIOR WARNING LEADING UP TO THIS. Why isn't there any warning BEFORE it gets to this" This is an accident waiting to happen. Do you know how many accidents would happen if every car just shut off like that because of some faulty charging system. Any other car would have warned you before hand. It's by the grace of God I was not slammed into while crossing a busy street and this damn car shut off leaving me right in harms way with cross traffic. AND another time it shut off on a busy highway. COMPLETELY DEAD. No functioning hazards. It's not right. This last time, The dealership told me there is a recall on the car for the safety plug and that was replaced. I was also told I needed a new battery and new power relay assembly. Those parts are related to the safety plug and the operation of the charging system. Why are those parts not also part of the recall" The dealership charges a diagnostic fee when they already know what the issue is. Must be nice. Everyone involved is building their own karma. I'm very displeased with this Brand. I will never buy another one and I will tell everyone I know hyundai does not stand by their product in making sure it's safe and operational. And they leave the consumer stuck with a bill that was their fault. FYI I had a prior complaint case with consumer affairs. (The mileage I stated was when it first happened. Now it's at 90k)

I am filing a complaint due to the lack of timely fix of this recall. It has been more than four months since the recall was issued (NHTSA Recall Number 23V651000) with no repair available.

- Eugene, OR, USA

I have a 2014 Hyundai Sonata that had its engine replaced as part of the recall. The car was taken to Hyundai of Central FL in January 2022 and repairs were completed in May 2022. Since that time the car has had several repairs that I feel are a cause of the faulty engine and or engine related to the replacement. These repairs include oxygen sensors both front and rear replaced, additional sensors, catalytic converter, transmission flush. Just in this month the car has been taken to Greenway Hyundai in Orlando weekly for a check engine light. The car was taken last week after the check engine light came on again and oxygen sensors needed to be replaced again. After the car was picked up last Wed, the check engine light on again and is currently sitting at Greenway Hyundai in Orlando for additional diagnostics. I may have to pay for diagnostic fee again and additional repairs again. So far, the repair costs exceed $3,000. The car displays show that it is one notch from overheating, runs a little sluggish, knocking noise at times and are experiencing similar issues when prior to when the engine was replaced initially back in May 2022. I am afraid of the car seizing up while I'm driving potentially causing an accident or fire as several consumers have noted the same. I have corresponded with Hyundai Corporate on several occasions asking for assistance as I quite frankly do not feel safe Hyundai or Kia vehicles. I had also asked for some type of assistance with my repair costs again that I feel are engine related otherwise why else would the check ENGINE light be displayed. In all instances Hyundai Corporate has simply skirted the greater issue and provided me with a staged response. Now I-??m being told that possibly the injectors need to be replaced on a car whose engine was replaced less than 2 years ago. I-??ve asked Hyundai several times to replace the car in like kind and quality because they are allowing a car to be unsafe to be operating.

Engine started making a weird knocking noise & was smoking from oil lid. Was driving & the noise got louder & then started to making a squealing noise. Started heading towards the dealership & it slowly started loosing power. Got to the turning lane to turn into the dealership parking lot, car immediately died in middle of road causing me to almost be hit by another vehicle. It started up long enough for me to make it into the parking lot. Car is now currently sitting at dealership waiting till Monday for Hyundai Service center to look at it. I originally had an appt scheduled for Tuesday to get it looked at but it didn-??t last that long. speed limit was 35, I couldn-??t even drive over 20 mph & had my emergency hazards on.

In May 2022 the engine was replaced as part of the Theta engine recall. Since that time the vehicle has been taken back to the authorized Hyundai dealership for oxygen sensors and a catalytic converter to be replaced. The check engine light is still on and out of pocket expenses are in excess of $3000 and growing. Hyundai corporate is refusing to cover any of these expenses stating that it is not engine related. In the meantime the car check engine is still on and by not taking responsibility for this has caused a safety issues as it is a known fact that their cars have a history of catching fire and I-??m fearful that this may occur unless Hyundai takes responsibility and reimburses for these repairs and/or replace the car with one in like, kind and quality. It is my firm belief that Hyundai is well aware that when the engine was recalled it created issues with other parts such as oxygen sensors, catalytic converter, etc to fail and by not taking fiscal responsibility has created a safety issue for millions of Americans. I am begging the NHTSA at demanding Hyundai replace the vehicle and /or reimburse for additional expenses mentioned above as I am not the only American having to deal with Hyundai-??s negligence. Simply saying it is not part of the warranty is not an inclusive defensive when millions of American lives are at stake.

As I was driving on the interstate, 25 or so miles away from, my car started to shake and the service lights appeared on the dashboard. I pulled to the shoulder of the road, and shut it off, i turned it back on and it ran for maybe about 10 more miles until it happened again. This time, I turn it back on to get it to run and it doesn-??t even begin to shift into drive. It started making a grinding/knocking noise from the engine & shaking, so I shut it off. I had to get it towed home and it has just been sitting in the drive way for a couple weeks now because it-??s undrivable. I had no knowledge prior to this incident of an engine recall issued on the car, the dealer I bought it from didn-??t inform me and neither did my lien holder. I contacted Hyundai of Slidell and they said since these open safety recalls have not been addressed that they will just reject them. There are about 2 from before I even bought the car that were issued in 2017 I believe that have not been completed. I bought the car in October of 2021 and was not informed of these safety recalls. Prior to this incident, no warning service lights had appeared and I was never told that I need to get my engine inspected as it ran fine.

My engine is burning through oil and also smoking while driving and has a burn smell coming through air vent. I scheduled to have it repaired and have a screenshot of the recall but when I took it to get repaired they stated there are no recalls on my vehicle and I would have to pay. I then called Hyundai customer service and was told they see the recall in one system but not the other and that they will give me a call back. I then never received a call back so I called again and was told that they cannot fix the engine recall and that I would need to get a diagnostic and pay for it myself.

UNKNOWN: my wife took the car to go to the store by our apartment. She was going through a roundabout at 10 maybe 7 mph when the car just shut off. We took it to AAA. AAA told us that it was an engine failure, and that there was an engine recall on our vehicle. We still thought it was the Ater. We took it to a shop called Gulich. They saw the engine factory recall and informed Chapman Hyundai in Scottsdale to repair the vehicle. Spoke with a Nick who told us that he would give us a free loaner as they fix our vehicle, and that it was under the recall. Got a call two days later from Nick stating that there was sludge in the car and it was from the previous owner, that is why they-??re not fixing it. The previous owner only had the car for two years as we receive the car in 2016 with 36,000 miles on it. Every oil change, tuneup, air conditioning, etc., we were told that the car was a queen puff, and that there should be nothing wrong with it. This is just an unfortunate misunderstanding, I would like to have my car fixed they are pressing me to return the loaner and my wife is in the hospital. Trying to leave me stranded. Please help.
