I have a 2012 Hyundai Sonata Hybrid that has a problem with its ABS Module. It is overheating and causes my car to stop its brake and motor functions while driving. I contacted the dealership to get a rental or replacement in the meantime and they told me there is nothing they can do and to drive with caution. I called the manufacturer to get a rental for the meantime and they told me the same thing. I have looked on the recall documents and it says they should give me a vehicle in the meantime if it is unsafe to drive. Please, I don't even want the car at this point because of all the problems with it and with my dissatisfaction with customer service from any Hyundai business. But if I could just get a car that is safe to drive while I wait for the recall to have a remedy, I would take that.

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. Brake pedal still goes to the floor. After restarting the car for 30-minutes- 1 hour, there are no warning lights or alarm. The car can be driven again. I brought to independent mechanic and found the code C1604 and there-??s a recall 251 on ABS brake system- recommended to bring to dealer. Brought to dealer, they say that recall 251 had no fix yet. They diagnosed that the safety plug relay needs to be replaced. Dealer replaced it and said that the car is fixed. Pick up the car from the dealer. After 20 miles of driving the same problem occurred- 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. Had the car towed back to the dealer. After 2 days, the dealer says it-??s possibly a transmission issue. I asked how come it wasn-??t diagnosed the first time around? No clear response.issue occurred 4 times already.

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.

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.

Then on another day the brake light in the back window, got stuck and the turn signal wasn't lighting up(no brake, nor turn signal lights but it showed in the car like it was working.when hitting the blinkers. I have taken it to several car shops even the dealership to have it checked out. I was told that it wasn't nothing wrong, but got stopped by police on numerous occasions cs the car didn't have Bck lights. The last shop i took it to said that it was the cars electrical system. I've checked to see if there was recalls.Doesn'tshow anything. It should be recalls on this, cause that's a safety hazard. Knowing you just changed out the lights and then boom u have no lights to show your turning or just on the road period at night. This is dangerous, I've almost got rear ended by a semi n other vehicles that was behind me and i had my granddaughter in the vehicle. Please check into this for the safety of ppl like me.

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.

Approximately a month ago I notice that my passenger side low beam head light was not working on my 2012 Hyundai Sonata so I purchased a replacement H7 halogen bulb thinking it was simply a burned out bulb. I replace the bulb with the new bulb only to find the low beam was still not working. I tried the new bulb in the drivers side to rule out a bad new bulb. The bulb worked fine in the drivers side. I also inspected the connector found no obvious problem. So far I have not been able to get the passenger side working so I did some on line research and found that this is not an uncommon problem on Hyundai vehicles and particularly with the Sonata. It appears that this is a wiring or computer issue not easily resolved. I believe this is a significant safety issue that Hyundai should repair at no cost.

Came Home Saw that the break lights were on in my Sonata. Tapped the brake pedal, they went off. Came home the next day same thing. I found a re call (google) for stuck brake lights. 2011 - 2012 Sonatas. I purchased the car used, and was informed that everything is working and in order. I'm just curios if there were any other reports concerning this matter?

I recently purchased a Hyundai Sonata hybrid with 132K miles on it and it has been driving fine for at least two weeks until a few days back the car has been displaying a recurring alarm on the dashboard telling " hybrid system warming! Safely Stop and Do Not Drive " now as soon as I turn on the vehicle the alarm comes on immediately. It's been a week since the car is technically inoperable because if I attempt to drive the car it makes this horrible grinding sound which is terrifying considering if I drive like this it would probably cause more damage to the car, and I have look for information on this issue and have found many of these cases over the years that I can relate to but unfortunately there's no a recall of this problem. I'm taking the car to the dealership soon but I don't have any hopes that they will find a permanent fix for this since nobody has apparently. I'm just trying find some help with this issue. So far I just have lots of regrets about this purchase and just hoping I can find some help with this matter.

The lighting system on the front and back lights, tail lights and brake lights are shortaged and melts the housings thst the bulbs go in. I have had two of these cars with the same identical problems and my son has had two sonatas and I have more people that-??s having the issue as well. It-??s very dangerous because the tail lights work whenever and me as the driver can-??t see behind me nor the person driving behind me will know that I-??m stopping. I can-??t drive my vehicles at all at this present time and has made s appointment with the company, Hyundai and filed a complaint as well. Something has to be done quickly to put this on the recall list because it-??s very dangerous for myself and others on the national highways

There is a recall of our 2012 Hyundai Sonata but Hyundai never informed us of the recall. https://autoservice.hyundaiusa.com/Campaign132/sitecontents/English/CustomerLetters/site_97_page_1530_customerLetter1.pdf#pdfjs.action=download Our car qualifies for the recall but Hyundai does not want to do anything about it. Our car experienced engine knocking and we took it to an independent repair shop. The repair shop informed us about the recall but Hyundai never did. The recall is because there is a defect in the engine in which friction caused by metal bits burned up the oil. The low level of oil causes the knocking. The repair shop filled our car engine with oil. We took the car to a Hyundai dealership but they refuse to do the repairs unless the engine is knocking even though the recall letter admits there is a potential safety issue if the engine is not replaced.
