The first time I went out to start my vehicle and it wouldn't start while in my driveway. I called Hyundai freehold and they said there 'may be' a problem with the engine but they wouldn't know until they brought it in. (really, even with the massive recalls across the nation? okay.) they would not pay for the tow. They would reimburse me after the fact. I played dumb and had it towed to them but reported it to Hyundai corporate. Then Hyundai of freehold admitted there was a recall on my vehicle and they would give me a new engine. The second time I was coming out of the college from a night class and it wouldn't start. I called them the next morning and they said the same thing (we won't pay for the tow we will reimburse you). They knew by the second time around that I had purchased a third party warranty so either way they wouldn't be stuck with the bill. I had it towed by the third party and paid the difference as the first time. This time they said it was the starter. (hmmm, okay). Now here I am a few months later. And I go out to my car and the car isn't starting (again). Should I bother to call them and ask them if they will pay for the tow this time" what's the difference right as long as I'm not paying anything but he difference after third party payment you ask? it's the principle! also, what happened when my third party agreement runs out and these knuckleheads are still saying (we have to see if it's something we did!?! or worse yet, something happens while I'm out with my two year old?! they are clearly doing this to other people I checked their yelp page I'm not the only victim. Please help"! I can't afford to wait until my third party warranty is up for them to fix the problem or give me a vehicle of the same value mins the problems. It's literally been one thing after another since I bought the car. And forget about asking for a loaner!

I believe my car has been affected by the NHTSA campaign number: 15V759000 brake pedal stopper pad deterioration I have noticed that when the brake pedal is not being pressed, the brake lights do come on and stay illuminated preventing accurate communication to rearward following vehicles that the vehicle is slowing or stopping. Additionally, I have been able to shift the the transmission out of park without depressing the brake pedal. Lastly, when this all occurs while driving my vehicle loses power as off I am pressing the break. This has occurred while driving on the street, highway and while turning.

While on the freeway, the car was making hard shifts when accelerating and decelerating. Then it slowed and gas pedal when pressed was like being in neutral, then it would catch and stop again...then had no power at all. Extremely dangerous. Was able to pull over after nearly causing an accident and was towed to the dealer

The contact owns a 2012 Hyundai Sonata. The contact stated that the rear tail lights had an internal electrical short and contained rust and corrosion. Also, the sockets melted on both sides of the rear tail lights. The rear passenger side light had to be removed to prevent the middle rear brake light from remaining illuminated. The rear driver's side tail light was operable, but eventually shorted out as well. The contact ordered replacement tail lights three times, but the failure recurred each time. In addition, the contact heard a loud noise concerning the fuel system. When turning the steering wheel in either direction, the contact heard an abnormal noise intermittently. The vehicle was included in NHTSA campaign numbers: 18V137000 (seat belts and air bags) and 18V934000 (engine, fuel system, gasoline); however, the contact did not receive any notifications. Mcgrath city Hyundai (6750 w grand ave, Chicago, il 60707, (773) 889-9090) was contacted, but had not diagnosed or repaired the vehicle. The manufacturer was notified of the failures. The approximate failure mileage was 90,000.

Well I bought the car a few years back. I learned about a few recalls on the car and took the vehicle in. They fixed one issue, while they said the engine was fine. 2 years pass and I was driving on the freeway. Note there where no signs of the engine having trouble. Just passed smog. Had the oil changed, the air filters and intake filters changed. The car makes this noise like a rattle noise. I turn off my music and was listening to the noise. The car seemed like it was losing power while I was driving and accelerating was declining. All of a sudden che K engine light comes on. Not even a moment later the engine turns off. I was scared. On the freeway and my steering locked up couldn't use the brake and wheel was useless. I was able to get the car restarted for a moment to get to the side of the freeway and down to a safe area but then the car stopped again and wouldn't restart. Has it towed home. Not only was this highly unsafe, it put my life my kids life and other drivers at risk in getting into a severe accident. I was lucky. But the experience was something else. Also the seat belts dont always lock in after the first try. U have to buckle 3 times before it stays

Engine seized on express way. Had to be towed. Engine replaced. Now we have a recall. Stating "during engine replacements under recall campaign 132 and 162, the high pressure fuel P ipe may have been damaged, misaligned, or improperly torqued during the engine replacement procedure, allowing fuel to leak. A fuel leak in the pressence of an ignition source can increase the risk of fire. We believe we cannot safely drive our vehicle.

My car started making a loud ticking noise in the engine, I took it in and they told me it's normal but when I bought the car it was not making that noise at all. It no longer fills to 410 miles when I put gas and the gas does not last as long as it used to. When parked and the car is on it will start shaking

Sonata had a noticeable decline in acceleration minutes before the engine had a small fire. The car was chugging slightly when stopped at a red light and after completing the turn, all of the dash lights illuminated and I quickly pulled over. After shutting the car off and trying to restart it, the engine began smoking. During this drive on local streets, I never went above 45 mph and wasn't driving the car hard.

While I was driving on the freeway last night my car stalled. There was no warning lights, sounds or smells coming from the car. As my car began to slow down I was able to maneuver myself to the shoulder avoiding an accident. I put the car in park and turned the car off and attempted to restart with no success. I had the car towed to my home and tried starting it this morning, nothing. It would click, the dash lights would come on but still will not start. I contacted blue link and they told me all system we're green on their end and could not see anything wrong with my car and could not do an on demand diagnostic for my car, I would have to get it to a dealership for them to perform the diagnostic tests. I had no problems with my car, I activated the blue link product 2 days ago and now this happens. I see there has been 8 recalls on this vehicle by visiting this website. I've had this car a little over a month. How can I find out if any of the recalls have been repaired and if any of the remaining recalls could stall the engine. I was told about 2 recalls: #174 airbag control unit and #953 software update to engine control module.

Sonata

  • 124,000 miles
While driving in traffic car began to jerk and lose speed though the engine was running. The car stopped in the middle of moving traffic. Transmission fluid spilled out profusely. Transmission was replaced but started to slip again the same day I picked it up after new (remanufactured) transmission was installed by the Hyundai dealer. Prior to this transmission issue, the alternator in my car failed while driving in the middle of moving traffic. This complete transmission failure occurred shortly after a new engine was installed because the original engine seized and failed prior. Alternator was replaced. The newly installed alternator failed again. A new alternator was once again installed. I am now having similar electrical problems yet again and there is a current concern that the vehicle may possibly stop suddenly and hazardously again while in motion.

Sonata

  • 150,000 miles
I pulled into a parking spot and noticed nothing out of the ordinary with my vehicle. When I was stepping away from my car and pushed the lock button there was no clicking sound. I continued into the building and returned to my car a few minutes later and it would not start. All of the lights would come on, but the brake locked up and the car would not start. I attempted to charge the battery which did not work. I unhooked the battery cables for a period of time to reset the lock system and possibly unlock the starting system, which did not work either. It has only been two weeks since I took this vehicle into the dealership to have the computer system updated due to engine failure issues in other vehicles. I purchased this vehicle less than a year ago and it does not show from what I can tell a recall. However I was instructed by the dealership to have the car towed into them so they can check to see if it is engine failure or a number of recall issues that I have not been aware of.

Vehicle was drove for approximately 3 weeks with a used motor, fully inspected and replaced per Hyundai protocol at a registered repair shop after Hyundai denied my motor replacement. Vehicle died due to bearing failure, when brought to Hyundai was immediately denied without entering repair facility due to "vehicle history". video can be provided, cannot attach. Fire was due to starter motor catching fire at failure. Extinguished myself.
