I was driving on the highway and my engine violently started to shake and I pulled onto the shoulder and the engine shut off. I-??ve had oil leak and engine problems with this car for 2 and a half out of 3 years! I-??ve had to buy countless gallons of oil. Multiple spark plugs, coil packs, etc. You can-??t drive the car for one whole minute without it stalling in traffic and almost causing accidents. So I can-??t drive it!

No check engine light was on. Heat cold gage was normal. No lights indicated what so ever. Engine started knocking really loud turned off while driving 70 mph on the freeway when it turned back on wouldn-??t go past 20 mph. when accelerating knocking would increase. Wouldn-??t accelerate past 20 mph. Took my vehicle to my local Hyundai dealer to be assed and they told me about the 953 campaign recall. I knew nothing about. I am 4th owner to the car from a used local dealership. My local hyundai refused to replace engine as well as corporate due to 953 campaign not being installed prior to engine failure. I only had the car a year and half and engine always sounded abnormally loud. I did tell the dealership this when we purchased the car as well as a few times throughout the time we went to make payments in person and they said it was normal Hyundais have loud engines. ultimately engine turned off while driving 20 mph and failed to turn back on at all. Out of a car since July 3 2024. No rental car was provided to me and had to pay for the diagnostics fee of $195 that was suppose to be waved once claim was approved but due to the 953 campaign not being installed by any of the previous owners or dealership my claims were denied! Now Hyundai wants $9,000 to replace engine with new belts and labor together! I don-??t even have that kind of money at all!! RIDICULOUS!!

On June 30, 2024 I was driving a 2015 Hyundai Sonata and the car caught on fire. There were no warning lights/ dash indicators/ no check engine lights or other warnings present. I had just exited the highway and while sitting at a light, smoke began emanating from the hood and within seconds the smoke turned dark brown at the vents near the windshield. I immediately exited out of the vehicle. I did not have time to pull over out of traffic. The car was engulfed in flames within a very short period of time. I had only seconds to exit the car. I would have struggled to get any passengers out of the backseat safely (i.e. kids in car seats) had I not been the only one in the car at the time. We had notified Hyundai of engine concerns that began in 2023, and they had given us the runaround for many months requiring us to submit paperwork for oil changes for the lifetime of the car and to keep returning to the dealership for "testing" after driving a certain # of miles. They required us to bring the car in to have pictures of the engine taken to ensure there wasn't "neglect" to the car on our part. This excessive and lengthy process by Hyundai took several months after initial concerns were brought up with the dealer. After being required to submit voluminous amount of paperwork and several trips to the dealership for "testing", Hyundai finally agreed to replace the faulty engine. We were told we could continue to drive it until a new engine was ordered. The new engine was scheduled to be replaced on July 11, 2024 however, the car burst into flames on June 30, 2024. Had Hyundai taken appropriate action when the issue was first brought to their attention, this incident would have likely been avoided and had not endangered my life and others helping. Thank you for your attention to this incident.

In April 2023, I purchased a 2015 Hyundai Sonata Eco from Carvana with 56,000 miles. By May 2023, the mileage was around 72,000. While driving from South Houston to North Houston on [XXX], 2023, the car loudly popped as I exited the highway around 5:00 pm CST. I noticed smoke coming from the rear and parked in a construction zone near a convenience store. Upon inspection, the vehicle stopped working, and I saw a significant fluid leak underneath. A bystander alerted me to flames from the bottom and under the hood. I called 911, and the fire department arrived to extinguish the fire. Fortunately, there were no injuries or property damage. I later discovered that specific 2011-?"2015 Hyundai models had been recalled due to fire risk (NHTSA ID: 23V-651000), but this did not include the Hyundai Sonata Eco. The recall was due to the anti-lock brake system (ABS) module leaking brake fluid internally, potentially causing an electrical short and leading to a fire. I have photos and videos documenting the incident. Following the incident, I filed a claim with Travelers Insurance, and on May 28th, 2023, the vehicle was declared a total loss. While I appreciate their offer of ~$13,000, it is insufficient to cover the remaining loan balance of approximately $17,300. I am worried about the financial impact and potential danger I face due to this malfunction. The lack of information highlights the need for better consumer education. I am now looking into options to cover the remaining loan balance, acquire a new vehicle, and, most importantly, advocate for improved driver education regarding this defect.

My 2015 Hyundai Sonata Sport with 63k miles does not show any open recalls relating to fires however, my car was parked, went to turn it on, smelled an electrical smell and white smoke began billowing out of the engine. Within minutes the vehical engine compartment was engulfed in flames. I was able to remove my family from the vehicle and fire department came out to extinguish the vehicle. Thankfully everyone movedthere vehicles and no other vehicles were impacted but insurance has inspected the vehicle and determined it's a total loss as the whole engine compartment is melted. If not for me thinking and the action of others, many others cars could have been burned and my family burned and injured as they are still shook up about. Hyundai offered me a low settlement but there is know recall on the specific VIN for electrical or engine issues. The following weekend I met a guy who just purchased a pre-owned Hyundai and after leaving he stopped at a red light and the vehicle engine compartment went up in flames while parked. There is a larger issue at hand here and please help us investigate this so no one else has to go through this nightmare.

UNKNOWN, car was driving fine on the highway, then all RPMS were lost and the car couldn't accelerate past 40mph. At the same time a loud knocking started and when i was able to park and pop the hood, the engine was clearly vibrating and the source of the knocking is undetermined. there are recall's for improperly welded rods in the 2013/14 model sonatas and the 2016 so i find it hard to believe that Hyundai doesn't know that this year and make would have the same known issue and those models have all had recalls already except for mine...

I have had my car serviced twice by the Hyundai dealership for the same exact issue. I believe I was told it was a knock sensor. A refurbished engine ended up being put in. The car is still having the same issues as when I first got it serviced in 2021/2022. My car is sputtering, loses power when accelerating and stalling. My car has always had an oil consumption issue and is causing additional issues with spark plugs.
