2012 HYUNDAI SONATA Complaints

When driving. Slow down to turn or to use round about car goes into EV. When i go to accelerate the gas motor will not re engage and the hybrid alarm system will go off. I lose all power to go any where. I have to pull over shut my car off give it a min then restart so the motor will come back on so i can drive again. I have to do this mulitple time in a 20 mile drive.

Engine suddenly shut off middle of the road while driving and will not restart. No warning lights came on prior to the engine failure. My family safety was put at risk since engine shut off middle of the road and I had to push it to the corner lane. Just imagine if I was on the middle lane on a highway when this happened. Alternator, battery was checked by a mechanic...no issue.

We received a recall letter for 198 and 251. We called and made the appointment for September 9, 2024. We took the car at Five Star Hyundai of Macon. 3010 Riverside DR. Macon, GA 31210. Phone: (478) 309-8308. We called in October to check on our vehicle status, so they are still working on it. We called back again because they didn't communicate well with customers and told us the car was ready. We went to the dealership to pick the car and when we got in the car to leave, without doing anything, the brake light came on and didn't move. We were never able to go because of this. The mechanic came and took the car and said let me check. He took the car for a short ride and said we need it to keep it. Then, they called tell us that the car needed a brake module and that would cost us 6700 dollars. I said that is unacceptable because the car worked fine when we took it to you for a free recall. They reduced the price to 3000 dollars and our car is still with them. We want our car fixed and running but this is not the way it should have to be. Our car is still in Macon at 5- star Hyundai. Few more days and we will 5 months without car. They never provide another vehicle. This has put us on a hardship because my husband goes to work early, then comeback and pick me up and take me to work then, he has to picked me up too. We have called the corporate office and have received a case number. The only communication that exists is between the corporate offices of Hyundai and us. The dealer will not return calls or texts. We haven't got any updates recently. They only thing we got told on Christmas time it was we must bring a check or a card to be able to pay. We have been paying insurance on that vehicle for what? If we haven't be able to drive. We are frustrated. We live about 95 miles away from the dealership and we can't check on our vehicle that easy. You don't know how much we regret this and how we really going to know if they are doing a good job or not.

I’ve been having issues with my Gas Gauge not recognizing how much gas I have in my car. I can fill my tank up, and the gas light constantly stays on. I’ve been looking online and came across other Hyundai owners having the same problem. I also have been having what seems to be an electrical issue where my passenger door, does not open and it’s intermittent which also seems to be connected to why my car ceiling light won’t turn on all the time. Lastly, I have to constantly change the head light bulbs and the break light bulb. I’ve owned my car for 3 1/2 years now, and I shouldn’t have to keep having to put money into it when it seems to be a known issue.

Car went complete stall after a warning light came off “Hybrid System Warning - Check Brakes” I am completely braked, but when I slowly releasing the brake pedal, there’s was a loud grinding noice and the wheels wouldn’t go forward at all, so I have to step on the brake again . I got stuck IN THE MIDDLE of the road and couldn’t park on the right curb since the car randomly got stalled completely. It took almost 40mins for the warning issue to go away and the car went back to normal. However, IT’S COMPLETELY A SAFETY ISSUE for the car to randomly stall in the middle of driving! I could be driving to fast traffic on a freeway or wide street where accidents can occur since I couldn’t even drive it a bit to park on the curb. On top of this - I occasionally get “hybrid system warning” whenever I am in the middle of driving and I always have to pull over and wait at least half an hour for it to go away, it’s been happening for few years now, and tonight was the most dangerous one so far!!! Please make Hyundai do a recall on the hybrid battery diagnose or replacement

I took the car to the dealer because the codes was reading engine assembly issues. I took it to the dealer and they stated it was the knock sensor and they got it approved to replace it now they saying it's the engine and it was denied. I just got the engine from the dealership in 2020

In October of 2023, I was driving my 2012 Hyundai Sonata Hybrid to the laundry mat about a quarter of a mile from my home. I stopped at a stop light and all of a sudden, a warning sound burst from my dasher board. The message stated, "Hybrid Warning-DO NOT DRIVE: CHECK BRAKES". The brakes completely stopped working, the pedal was to the floor and the accelerator was stalling. After managing to get the vehicle back to my home, naturally I went to the Dealership (Langdale Hyundai of Valdosta) and informed them of the issue. They informed me there was no issue, charged me for a diagnostic and sent me on my way. Once I provided proof of my car stopping mid-drive, they began to check wiring and such. What they told me the issue was is a Hydraulic Power Unit. I had it replaced, still the same issue "CHECK BRAKES". I only have 116k miles on this car, bought it with 72K in 2021, so I haven't driven it much. It spent 8 months in Hyundai Dealership in Holiday, FL for a brand-new Hybrid Battery in 2022. I have been looking online for anyone that knows more about this issue so I can get it resolved. It turns out there are thousands of people who are just like me. I believe this is indeed a recall issue. I believe this is an issue is an emergency issue, brakes giving out while driving is an issue that needs to be addressed. This has been happening for years, and Hyundai has not done one thing on it. It's happening with newer vehicles as well as older. Langdale Hyundai of Valdosta was not much of a help at all, to be honest, I don't trust their workers at all. I believe they do nothing and charge customers for the max that they can.

The contact owned a 2012 Hyundai Sonata. The contact stated that various functions on the steering wheel including the horn, cruise control, and other electrical functions; all failed to operate as needed. The vehicle was taken to an independent mechanic where the contact was informed that a warranty had been placed on the vehicle for the clock spring which they linked to the failure. The steering wheel also began to stick soon after the diagnosis. The dealer was notified of the failure; however, the dealer could not provide an appointment until months out. The contact then stated that while driving at 65 MPH, the vehicle began to hesitate upon the depression of the accelerator pedal. The contact began to pull over as the EPS(Electrical Power Steering) and several other warning lights appeared on the instrument panel. As the contact opened the door, a fellow motorist had also pulled over to alert the contact that the vehicle was on fire. Soon after exiting the vehicle, the entire vehicle quickly became engulfed in flames. The fire department quickly arrived on the scene and extinguished the fire. The contact was not injured, no other occupants were inside the vehicle, and the contact was unsure if a fire or police report was filed. Some of the grass and trees in the area had caught fire as a result of the failure. The remains of the vehicle was towed to an independent tow yard. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle was completely destroyed. The failure mileage was approximately 125,000.

ACTIVE HYDRAULIC BOOSTER failed while driving. 2012 with 114,000 miles on it. Brand new engine and transmission installed from prior recalls. Hyundai dealership said it was covered under anything and would cost $5K to get fixed.

The passenger rear door will not open from the inside OR the outside. The door lock on the inside of the car will not open. Door is in locked position. Problems like this are all over the internet regarding Hyundai cars. This is a safety issue because someone in the back seat can NOT open the door and are potentially locked inside the car with no way out. This could be life and death if there was a fire, accident, etc. Independent repair center has inspected and confirms. No warning lights. Just happened in September 2024.
