2012 Hyundai Sonata on May 8,2020 Hyundai replaced my engine due to a recall.on August 18,2020 I had complained about the smell of gas that I smelled in my car. They inspected my vehicle and said it was fine. But every so often I kept smelling gas inside my car but no engine light or any light turned on and plus I thought it was fine since Hyundai inspected my car but February 4, 2021 I was parked with my vehicle running and the fuel smell started getting worse, entering my vehicle through the air vent. My vehicle would smell like gas even when it was turned off. So I turned my car off and I heard loud boiling bubble noises inside my car which is strange. I waited a few minutes turned my car on and then my thermostat maxed out all the way to hot so I shut my car off. I callled Hyundai & took my car to the palm springs dealership and they inspected it and told me that it's the high pressure fuel pipe. My vehicle is still at the dealership because I can't afford $1000 to pay for something that's a recall. Especially since I complained about the gas smell on August 2020. Also my right tail light is completely out. I replaced the bulbs multiple times but it ended up burning out. The wires are burnt and melted. This is car is nothing but problems.

As I was pulling out into traffic, the throttle went unresponsive. I pumped the accelerator three or four times and the vehicle lurched forward then begin driving normally. There was no "check engine " or other warning. I took the car into the dealer and they hooked it to a obd and drove it, to no avail. Has therein a any report of this problem by other oweners"?"

I had a very scary incident Friday night, 12/18/20 about 8:30pm. I was about to merge onto the 5 fwy North to go home, and as I am coming out of the turn, and accelerating to anticipate the flow of traffic, I see a big rig in my rear view mirror in the distance. Naturally, I step on the gas to punch it, to give myself and the rig plenty of distance as to not collide. My car revved up and decelerates to about 2mph. I panicked and managed to coast the car to the shoulder as far right as I could and the rig barrels down past me. I was afraid to completely stop on the shoulder of the fwy, and the car lasted long enough to coast to the next exit. I am able to continue steering my car close to the shoulder at a crawling pace, and turned on my hazard lights. I had people mad behind me, but I could not speed up. I managed to coast to the nearest exit, come down the ramp, and stop briefly with just enough momentum to steer left onto telegraph in commerce, and my car completely dies in the first lane. This is the second time my car just dies on me while I am driving! first time was three years ago in December 2017. The car had initially died while making a left turn. However, after turning the car off and waiting a few minutes, I was able to turn the car on and drive no more than 30 mph to the same downey Hyundai. The issue was under full warranty and repaired, but now a second time? worse yet, this happened while excelerating onto the freeway. I don't want to drive around in a car that has repeated recalls for various issues. I also don't want to worry of my car dying on me a third time. My Sonata is currently at downey Hyundai and they have started diagnostics and will have a better reading as to what happened. I have lost all confidence in this vehicle and worried for my safety and that of any passengers I may have with me.

My engine threw a rod at approx. 85000 miles (10/2019). Hyundai replaced the short block but since then I continue to have issues with my car. After they replaced the short block and I picked my car up, the car seemed to be running like it is not getting consistent fuel like it is supposed to. I have had it in the shop 4 times because the check engine light has come on. While I am driving, the car seems to lurch at random times and this issue has gotten so bad that this (what I call lurching) makes the cruise control shut off. One time I was using the cruise control to accelerate onto the freeway and the warning bells and whistles went off, the car stalled, then restarted itself with no check engine light on. The most recent time (10/26/20 - 11/10/20), they had my car for 6 weeks, they did not fix it. They put 337 miles on my car while they had it and I experienced the same issues I have been complaining about to them since the beginning, after I drove it 38 miles. They cannot seem to find what is wrong with my car or fix it. 10/2019 threw rod - replaced short block see attached 1/3/2020 replaced hsg belt - did not fix issue see attached date unknown - check engine light went off before they could run codes.unable to find issues - did nothing no paperwork 7/3/2020 - unable to duplicate concerns, provided software updates. 8/20/2020 I called san tan Hyundai and told them I continued to have the same issues. I told them I needed a loaner car as I have no other means of transportation. I was advised they did not have one available but would call me when they did. They never called. The check engine light came on again on 10/25 while I was out of town so I took it to them 10/26. I have paid for 2 rental cars now while trying to get this issue resolved. 10/26/20 trans reset recycle cleared codes - did not fix issue see attached

My car broke down on a busy highway during a lunch rush due to an engine rod knocking in the engine. It was a terrifying experience and even sitting still on the side of the road I was scared my car would be hit by any of the 70-80mph cars exiting the ramp behind me. I tried joining the class action suit but for some reason, even though it's the same engine with the same problem, hybrids aren't a part of the suit.

My car stalls, lags and shuts off while driving and has a strong scent of exhaust and uses an awful amount of oil but there are no visible oil leaks. There are no check engine lights on. I have taken it to the muffler shop who states no exhaust leaks are found. My local gateway and mike morgan hyuandi says it throws no codes when put on the diagnostic machine so I cant find out the issue. From research I see this is a common issue with this model cars and I feel this should be looked into because it is a hazard especially when it kills in the midst of traffic

Head lights and tail lights consistently burn out, rear tail lamps caused melting of the assembly on both sides near where the socket goes. Rectified rear lamp issue using lower wattage leds, not a solution for this but a band aid. Car automatic locks have ceased working, fan assembly cut on and off causing failure of radiator. Buttons on steering wheel activate wrong settings often when used. High pressure fuel pump stopped functioning, only low pressure system remains. All problems listed happen intermittently either moving or stationary.

I had a recall done on my Hyundai Sonata 2012 for the fuel pipe. I took it in to the Hyundai dealership in richland hills about a year ago, before covid19 I believe because I don't recall wearing a mask. They were extremely rude to me at the Hyundai dealership so I left there without knowing if there was a problem or not with my car. Now a few months ago I received another recall for the same issue an they said my fuel pipe needs to be replaced but aren't honoring the recall and are saying I must pay for the fuel pipe myself.

Having purchased the aforementioned VIN last month, the break lights stay on even tho the car is off, thus draining the battery. With a heightened fear of being rear-ended, or worse, for the now we disconnect the battery cable. Also, the car wants to stall when stepping on the gas pedal, the acceleration is delayed, this at any speed. Fearful of the engine catching afire, we appreciate post haste.

This week my vehicle experienced a fuel line crack where the low pressure fuel pump connects to the direct injection fuel pump. The smell of gas was evident within the cabin while both stationary and in motion, and I could see vapor rising from the proximal portion of the hood while sitting in the driver's seat. The gas leak could be visualized upon starting the car. Upon opening the hood, I noted the gas leak around the cracked plastic connection. The fuel line was the original genuine Hyundai part. The Hyundai dealership replaced it with a superior (non-plastic) fuel line. The lack of quality in the original fuel line is concerning because it placed my family directly at risk to experience a dangerous and possibly fatal fire. It appears that the Hyundai dealership was also aware of this problem with the original line which is why they replaced it with a different part. However, there is no current recall campaign for this unsafe scenario.

I had taken the vehicle to the dealership for a clock spring recall. I picked the vehicle up and the check engine light was on. I took the vehicle back to the dealership and they informed by the check engine light was caused by the high pressure fuel pump failure. This seems to be a know problem with this make/model/yr vehicle.

Was driving on major street with no warning the vehicle died in the middle of a major intersection. We tried to start the vehicle again with no luck. Gas hand showed we had gas in the vehicle, so don't understand why the car stalled and would not start again. Vehicle had to be towed home. Not sure if there has been a recall on the fuel system, however this was a very scary and dangerous situation. Stalled vehicle had traffic back up on very busy overpass intersection. Unknown to what happen nor why it happen

The fuel gauge has stopped working correctly, it jumps all around in mileage. Have no idea how much is in the gas tank. Have to fill after I go 300 or so miles just to be safe. The fuel mileage indicator will go from high 360 to 47 miles left and everywhere in between, the car can be sitting at a stop light or moving, makes no difference
