I noticed a clicking noise when pressing and releasing the brake pedal that had not been there before. I started hearing that sound 3-5 days ago. After driving to pick up food I noticed smoke coming from the engine area then the car burst into flames. The fire depress called a they put out the fire.
The headlights and rear break lights keep going out, we have changed the bulbs multiple times and they keep burning out and not within months it happens within weeks the bulbs completely burn out which has caused us to be stopped by police and given warnings. The headlights look very dim when on which as well have been changed but still give a dim look. The engine has given out, the last time driving the vehicle was a 60 mile road which it lost velocity momentum and the engine light turned on then it completely shut off almost crashing into a light post.
I started financing my 2012 Hyundai in 2019. Feb of 2021 the vehicle stopped without any warning. I paid to get the vehicle towed to Brandon Hyundai in which the did replace the engine and the starter free of charge. I was able to continue to drive my vehicle everything seemingly fine. Fast forward to late 2023 the engine light is back on, I-??ve taken my vehicle to Hyundai dealership several times relating to the engine light being on each time having nothing resolved in regards to this matter with Hyundai stating theres no one there who-??re able to inspect the engine. My oil light has remained on for a number of months in 2023 I-??ve had to get an oil change several times this year and Hyundai isn-??t able to explain as to why the vehicle isn-??t retaining oil.12/15/23 around 11 pm the vehicle began to make an unfamiliar noise, stall, jerk and not accelerate. I am now unable to drive my vehicle and have to loss hope in my vehicles reliability and most importantly my safety.
Alarm started and Hybrid brake check warning instructed to pull over and do not drive. This happened while driving down the road. The car lost power and would not accelerate. The brakes were gone and were making a grinding noise.
Illumination of the malfunction indicator lamp and/or ABS (Anti-lock brake system) light. My 2012 Sonata Hybrid has been towed twice to Key Hyundai dealer in Jacksonville, FL. They charged me several thousand dollars and the vehicle ABS lamp remains illuminated. The dealership did not offer me alternative transportation and I feel unsafe driving the vehicle. On Friday November 12th they blamed the brake lamp illumination on the Hybrid main battery and gave me an estimate of $12,900 to replace the battery. The first time I took the vehicle in for this problem my vehicle was still under 10 year/100,000 mile warranty. My car has approximately only 35,000 miles driven. They did not honor the warranty. This is a brake issue not a battery issue.

While driving on the freeway, the Hybrid system warning, safely stop and do not drive will alternately flash with check brake and continuously the alarm sound with the park brake red light. The car would loose acceleration, and the brake pedal goes to the floor when applied. Once stopped, I restarted the car and the same things happen. The car can accelerate on and off for about 5mph.

Due to the recall of my car's engine (VIN 5NPEC4AC5CH467757), on July 11, 2023, I dropped off my 2012 Hyundai Sonata to get my faulty and failing engine inspected at my local Hyundai dealership. After being approved for an engine replacement, I submitted the necessary paperwork proving ownership and routine maintenance of my vehicle. Two months of ineffective and infrequent communication went by thus leaving me without my vehicle. Unfortunately, Hyundai Motor America/corporate headquarters made it increasingly difficult to meet all their prerequisites to have my recalled engine replaced, which, ironically, is due to their faulty engineering. To replace the engine myself would cost nearly $5000. After finally being given confirmation that all necessary documents were submitted, Hyundai Motor America (HMA) denied my engine replacement stating completely false and confusing reasons. The reasons (attached) genuinely proved the company's disinterest in helping me; I have never requested an engine replacement before nor have ever owned a Hyundai before this one--which will be my last. When questioned, an HMA representative referred me to the Better Business Bureau, confidently believing the BBB would overturn HMA's decision. Unfortunately, the BBB was unable to assist due to the age of the car. Any class action suits against Hyundai only cover vehicles manufactured between 2013 and present-day. That said, my car is still unsafe and inoperable, which, with a pregnant wife (who is also in the National Guard), is absolutely unacceptable. I feel compelled to escalate this situation until it is resolved. With the above stated, I would like Hyundai Motor America to replace the current engine within my 2012 Hyundai Sonata and also provide proof of my previous -??requests-?? for an engine replacement---which do not exist.
Car completely shut down suddenly and spontaneously without ANY warning while my husband and I were driving on a very busy major highway at night. We were unable to do ANYTHING to control the car and could have died, been seriously injured, or caused death or injury to other drivers. We were then towed off of the highway after calling for help. We don-??t know firsthand exactly what failed. We were aware of our engine burning oil and had been to Huffines Hyundai multiple times previously for an oil consumption test at their recommendation. Upon completion of this test process no solutions for repair were offered, and we were never warned of any danger in driving it. We have found out via our own research that our car has a defective engine. This specific engine has been the subject of at least one class action lawsuit and Hyundai is well aware of its dangers. We have been denied an engine replacement by Hyundai as they are claiming negligence on our part as the reason for failure after we presented a substantial stack of oil change receipts. Not 100% complete, so they make this claim. These cars are death traps and people are dying because this company won-??t honor their warranty. Please do something.
The contact owns a 2012 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the vehicle made an abnormal sound. Additionally, the hybrid warning light illuminated. The contact pulled the vehicle over, self-inspected the vehicle, and noticed there was oil spread all over the engine. The vehicle was towed to the contact's residence. An independent mechanic inspected the vehicle and informed the contact that the crankshaft pulley bolt was loose. The contact stated that the vehicle had the engine replaced approximately 15 months ago. The vehicle was towed to the dealer, who informed the contact that the crankshaft pulley bolt was loose; however, they stated it became loose over time and that it was not the mechanic who replaced the engine fault. The vehicle was not repaired. The manufacturer was made aware of the failure and got in contact with the dealer to have the repairs performed free of charge. The failure mileage was approximately 135,000.
While driving, the engine abruptly seized up and stopped without any warning. This was a replacement engine from a previous recall. The transmission warning light had illuminated the previous day, after which the car began to hesitate when shifting from 2nd to 3rd gear but otherwise drove normally. When the engine seized up, every warning light illuminated on the dashboard. The car still had full battery power but the engine would not turn over or make any response when the key was turned. After placing the car in neutral and pushing it several blocks, the engine began to smoke. The smoke progressively and quickly worsened until fire was visible under the hood in the engine compartment. The engine compartment was then engulfed in fire which spread to the front of the passenger compartment. The car had to be extinguished by the local volunteer fire department.

This is a 2012 sonata hybrid. The vehicle popped under the hood when my wife was driving to visit her father. My son opened the hood and fire started shooting out from next to the exhaust manifold. The car was just into Gurnee Hyundai for service. They had the car for a month and a half. I still don't think that they did anything when they had it. Anyway, the car burnt completely to the ground in the front engine area. I already contacted Hyundai America, and, even Hyundai and South Korea. This happened on September 8th. I have pictures, I also have the warranty individual who inspected the car before the dealer worked on it, or I have the warranty information. They have the documentation.
Hybrid System Malfunction. The "Hybrid System Warning! Safely Stop and Do Not Drive" appeared on the vehicle dashboard. While traveling on the highway or in town the vehicle will want to slow down then stop. The dealership's (Wyatt Johnson Hyundai) Clarksville, TN, maintenance tech have troubleshot the vehicle. Since my daughter and I have owned the vehicle, it has been seen by the dealer a few times during this time a transmission replacement was completed for the Hybrid System Malfunction, which did not solve the problem and I had to pay out almost $6,000. Still, same issue arises and also, I was told by another tech that the transmission is sealed and should not have been opened. The only thing we heard from the dealer(Wyatt Johnson Hyundai) was to come and pick up the car. When my son-n-law went to pick up the vehicle, the engine was still torn apart. They said they would fix it and then let us know when it is ready to be picked up. We have not heard anything from the dealer (Wyatt Johnson Hyundai) at all, assuming they are still working on it. Until, we received a letter from Express Auto the the vehicle was towed and reported abandoned. So, I drove to Clarksville, TN and trailered the vehicle back to Las Vegas, NV to have the Hyundai techs here diagnose the vehicle.

The contact stated that the check engine warning light had remained illuminated. The contact stated while driving at 40 MPH, the vehicle shut off and failed to restart. The vehicle was towed to a dealer. The contact was informed that there were no recalls on the VN. The vehicle was then towed to an independent mechanic where the contact was informed that the timing chain had fractured and needed to be replaced. Additionally, the contact stated that the headlight and taillight bulbs would burn out and required frequent replacement. The vehicle was not repaired. The failure mileage was approximately 185,000.
The car completely shut off in the middle of the road. It coasted to a nearby gas station and would not crank back up. There was NO oil in the vehicle, but no leaks and is up to date on oil changes and servicing. After putting oil in the engine, the car was able to crank and we attempted to drive it home. It stalled in the middle of the road and completely shut off and would not drive. It had to pushed out of the middle of the road, stopping traffic and risking our safety. Two mechanics saw us and stopped by to take a look. Upon inspection of the oil/engine they noted metal shavings (gritty) oil and the engine sounded like a propellor when we tried cranking it. It is available for inspection, however it is currently sitting on the side of the road in someone's yard. This problem has been noted on a recall with Hyundai Sonata vehicles, (metal shavings inside the block, debris circulates through the block and ends up stuck in the oil galleries, which is exactly what appears to have happened) It has not been inspected yet, I'm trying to see where I can get it towed. There were no warning lamps whatsoever before it shut off. Now, the engine light is on. and the oil light came on after it shut down the first time, but went off upon putting oil in it.
