I got a 2014 Hyundai Sonata in May of 2023. In the beginning of September 2024, I was driving down the road on a highway and a knocking sound began as well as grinding. The car then immediately lost all power which could-??ve resulted in a serious accident like death or injury to me or others. I found out about the engine recall right after for the class action lawsuit for Hyundai. They told me I was good under the extended warranty. I was told that I needed to get the odometer branding fixed on the title before they would honor the recall. I did that and received the clean title in the beginning of November. The car was at a garage where they agreed that the car had premature worn engine bearings and had failed. The car went to a dealership in the beginning of November. Then I was told I needed more information like the clean title, bill of sale, and a statement. I provided all 3. After that I was told I needed to send receipts of my maintenance to the car. I also did that. I send every several documents. The dealership had told me my claim was denied due to -??maintenance neglect-?? and -??not enough maintenance documentation.-?? I then had the dealership reopen the claim and sent all of the prior maintenance records on the vehicle from the owner before me. I am told it is declined still for the same reason which makes no sense. I sent 35 documents to them. I was told today that they will not fix it and I was wished the best of luck. I did not have the car at the time of the recall and only had it for a year and a couple months. The car has been sitting for 4 months while I am paying insurance on it at the dealership to get the engine recall repaired.

To Whom It May Concern, I am writing to express my concern regarding my 2014 Hyundai Sonata, Vehicle Identification Number (VIN): [XXX], which is currently experiencing excessive oil consumption. I have recently become aware of Recall Campaign 162, which addresses a manufacturing defect that can lead to premature engine wear and related issues. Despite regular maintenance and proper care, my vehicle consumes an abnormal amount of oil, causing me to frequently top off the oil between oil changes. This not only increases my maintenance costs but also raises serious concerns about the safety and reliability of my vehicle. * trusted service provider has confirmed that the oil consumption in my vehicle is abnormal and is likely related to the defects outlined in Recall Campaign 162.** As stated in the recall, the machining errors during the engine manufacturing process can restrict oil flow to the bearings, leading to premature bearing wear. Although my vehicle does not currently exhibit any visible oil leaks, the oil consumption issue suggests underlying damage that could potentially lead to engine failure. Considering the potential risks and the known issues with the Theta II engine, I kindly request that my vehicle be inspected and, if necessary, repaired under the terms of Recall Campaign 162. I urge you to address this matter promptly to ensure the safety and reliability of my vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle suddenly spiked in RPMs, and suffered from a rattling noise. The following day after taking it to a known skilled service location, they advised to contact the dealership due to two open recalls. They found zero oil in the vehicle as well as issues with the valve seals. They then put the blame on the customer and did not acknowledge the engine recall that states clear problems with oil and engine valves resulting in a loss of oil and a failure in monitoring systems. At no time did the oil light show on the dash and there was no oil in the driveway where the vehicle has been parked. They advised us to contact the company for assistance. After doing so, the dealership, and Hyundai themselves have refused to acknowledge the engine issues or repair the car under the two known open recalls. We have spoke with reps from both the dealership and the company an have received no assistance in reclaiming confidence in the vehicle or Hyundai as a whole. This happened in September 2024 and there is no resolution in sight here in December. How a customer can be expected to repair at their own cost during a known recall with a class action lawsuit is ludicrous.

The contact owns a 2014 Hyundai Sonata. The contact stated that while driving approximately 70 MPH, the vehicle suddenly lost power and the contact was able to coast to the side of the road. The instrument panel was illuminated with several unknown warning lights. The contact restarted the vehicle and continued driving. Three months later, on November 11th, 2024, while driving approximately 40 - 45 MPH, the check engine warning light illuminated with a message indicating a failure with the Variable Valve Timing Solenoid. An independent mechanic confirmed that the Variable Valve Timing Solenoid was the cause of the failure, and the contact replaced the part himself. The following day after being idle at a stop light, the contact attempted to accelerate, and the vehicle failed to accelerate. The vehicle was restarted; however, there was a knocking sound coming from the engine compartment. The contact had the vehicle towed to the residence. The contact used an OBD machine to diagnose the vehicle and retrieved fault codes for an oil pressure failure which caused the engine failure. The vehicle had not been taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 120,326.

I was driving at a higher rate of speed 50 MPH in the center of 3 laned road no warning or indicator lights were on in my vehicle when the engine without warning blew and stopped working. Again no check engine lights were on no warnings were given. It shut down and would no longer accelerate or drive. We almost caused several accidents as this was a very busy roadway.

Stopped at a stop light, started going again, got up to about 20 mph and engine stalled on the side of the road. Had to wait HOURS for a tow, triple A couldn-??t help, had to pay $70 out of pocket. Now they are denying me for an engine replacement, each time I submit the documentation they request, they find some reason to turn it down, and when I ask what they specifically needed me to do, they just gave me a phone number to call for Hyundai customer affairs, even though I have already gone through all of this with them, and they directed me back to the dealership as far as communication goes. I-??m getting the run around, and it has been going on since May.

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)
