SERVICE BRAKES
On November 4, 2024 while coming to a stop in traffic, the brake pedal went to the floor without any warning. Just prior to using the brakes, there was no feeling of softness in the pedal, and no indication a low pedal situation, and there was no indicator of pending brake failure. The brake light indicator only lit when the brake pedal went to the floor. I was fortunate that I did not rear end the vehicle ahead, or more seriously had there been a jay walker, because i quickly pumped the brake pedal with what little braking I had while shifting the automatic transmission to second gear. I was able to slowly drive ten miles home in second gear while using the hand brakes. eom

ENGINE, SEAT BELTS
The drivers seat belt does not engage. The engine has been burning oil, misfiring, and even after thousands in repairs was returned to me by the dealership with continued misfiring. When returning the car back to the dealer service center days later after Hurricane Helene, the car continued to misfire and became so overheated the engine light was flashing. Upon calling for a tow, I attempted to raise the hood for the driver to locate the car, but the hood was so hot it burned my hand. The engine was so hot, I believe it was about to catch fire and would have had I not been able to pull over so quickly. Had I been driving on the Interstate, I have no doubt this car would have been on fire within minutes.

POWER TRAIN, UNKNOWN OR OTHER, ELECTRICAL SYSTEM
I believe the transmission malfunctioned as I reached 60 MPH / 4000 RPMs on the highway when it suddenly did not want to accelerate past that. The more I stepped on the gas pedal, the more it slowed down. I attempted to use the paddle shifters to shift up or down, but I was unable to shift up and shifting down did not allow me to accelerate past 4000 RPMs. The flow of traffic was faster than I could keep up with, and not being able to accelerate made it unsafe to be on the highway. I had to pull over, and get off of the highway. I found that others have reported this same issue online with the same make/model/trim, but I have not had time to take it in to be looked at. No warning lamps, messages, or other symptoms prior to failure. I only noticed when I got on the highway and needed to reach speeds greater than 60 MPH. Turning the car off, waiting a bit, then starting it again seems to have resolved the issue, but I am still uneasy with this having happened so suddenly. I fear the issue may return in the future based on what I have read online. The car is available for inspection upon request.

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.

The car has been experiencing oil consumption issues for the past 15k miles and it's getting worse hyundai says .y vin isn't under recall and they can't help me. My mechanic says my oil consumption is high and is concerned about potential engine failure. I have to add oil every 500 miles. The 2.4l engine has had major issues but Hyundai will not expand the recall. My mechanic has seen issues like this but Hyundai won't do anything. I have friends with engine failures in similar Hyundai models. This has been going on for about a year when I had mileages in the 77k range. I now have 99k and the oil consumption is getting worse. I am very easy on this car and always do full synthetic changes at the Hyundai recommended intervals for the severe driving schedule. I've never had a car costume anything close to the amount of oil I am using including two other Hyundai I have owned.

SERVICE BRAKES, ENGINE
My engine block or engine has a hole in it. All of my oil came out and my vehicle shut off. My brakes as well is not hard when pressed on, so I would have to pump it till it hardened. My safety and others safety was at risk while I was driving because my vehicle was not coming to a complete stop which could have resulted in a serious or fatal accident. As well as my engine block blowing making all the oil in my vehicle leak all on the road while driving on a busy road. Yes the problem has been confirmed BUT I was told that my car does not fall under the cars listed with the SAME issue on the recall list. No it has not been inspected by the manufacturer or police or insurance rep because I am being told I have to pay out of pocket and I am not able to afford the prices being told to me for an issue that I have not caused. There were no warning lamps or anything prior to this incident. I have went to many different mechanics for a diagnostic for my vehicle but they all say my vehicle is fine or they do not know what I am talking about.

STRUCTURE:BODY
The interior and exterior driver side door and driver side rear door handles are no longer functional on this vehicle. This is a well known problem with these vehicles that poses a grave safety hazard. In the event of a fire or accident, it would be impossible to exit or gain access to my vehicle without breaking the side glass. I have spoken to my Hyundai dealer and they agreed that it is a known, dangerous problem, however no TSB or recall has been issued. My only recourse is to pay to have this defect repaired. This is the first vehicle I have ever owned that has had this type of issue.

Engine burns too much oil and needs oil replenishment every 2 weeks while driving only 100-200 miles. This is extremely hazardous cause on highway the car can stall anytime which has happened in the past. The engine has been fixed for leaks before but still is burning oil and no mechanic will touch it saying it is a common issue of hyundai. Why is this model no part of the class action lawsuit?

Chest Clip, Buckle, Harness
I have the Chicco Fit360 and the magnetic chest clip is no longer magnetic it was coming apart with little to no movement. I would buckle the chest clip and then move it to put it in position and it would come apart. I know this is a common problem with this particular car seat and something needs to be done before a child dies or gets seriously injured because the chest clip comes apart while driving!
