2014 Hyundai Sonata Fuel system Problems

I am submitting this complaint regarding a serious safety issue involving my Hyundai Sonata. While driving under normal conditions, my vehicle suddenly entered a low-power ("limp") mode without warning. The vehicle would not accelerate beyond approximately 30–35 mph, creating a potentially hazardous situation in traffic. At the same time, the check engine light began blinking. The sudden loss of power significantly reduced my ability to maintain traffic speed and safely maneuver the vehicle. This condition could have increased the risk of a rear-end collision or other accident. I brought the vehicle to an authorized Hyundai dealership (Fred Beans Honda Of Abington PH# 215-392-9020) for diagnosis. The dealership confirmed that the vehicle stored Diagnostic Trouble Code (DTC) P1326, related to the Knock Sensor Detection System (KSDS). According to the dealership, the vehicle entered limp mode as a result of this fault. The abrupt reduction in vehicle power and speed occurred without sufficient warning and created a safety concern. I am reporting this incident so that NHTSA can investigate whether this condition represents a broader safety defect affecting Hyundai Sonata vehicles equipped with the KSDS system. Vehicle Information: Make: Hyundai Model: Sonata Model Year: 2014 I request that NHTSA review this issue and evaluate whether additional action is warranted regarding vehicles experiencing DTC P1326 and associated limp-mode operation.

After having work done to repair the head gasket and spark plug. I was on mile ~300 after repairs and was nearing to fill up at a gas station, I started losing power and notice the check engine light was on and Gas smell filled the cabin. When I stopped the hood started smoking and there was a fire under the engine cover. My Vin is not listed on the fuel line recalls and I believe this is an oversite as it lists, faulty High Pressure hose can rupture and cause engine fires and that is exactly what happen in my case. I believe this Vin was Overlooked and I need the repairs complete. I have not completed any repairs because I believe this should have been recalled.

Check engine light came on with a odb code of P0300. engine started to run rough and mileage dropped substantially. Upon arrival to my home due to safety issues I turned off car and and let it cool. My father read the odb with a code reader and said it smells like gas but we will look at in the daylight. Today upon removing the engine cover and checking the spark plugs we discover stains and residual stains on the ignition coil packs and directly under the low pressure fuel line where it connects to the high pressure fuel pump. it seems the plastic clip/connector is leaking at anout the rate of one substantial drop per 3-5 minute period. this could cause an out of control engine fire. Dealer was contacted and while there are two recalls regarding other 2014 hyndai sonatas for the same exact problem that this vin was not covered by the recall and the repair cost would be 300 for the fuel line plus labor.

My Gasoline Delivery Hose/line/pipe/fitting is leaking near the spark plugs as checked by a Tire Plus mechanic. The car is not safe to drive. Hyundai refused to fix my car under the Campaign 22V312000 that addresses this specific issue. They would not even open the car to see the pipe leaking. I would like to know if my car can be added to the campaign 22V312000.

There was the strong smell of gasoline so the vehicle was then parked outside of our garage. We had a scheduled appointment with our independent mechanic to have this looked at. Prior to the appointment, the Check Engine Light came on and was also flashing. The car was performing very poorly at this time. When the gas pedal was applied to accelerate the car sputtered and severely hesitated. We pulled off of the highway to a city street and then a parking lot to call for a tow to our mechanic. Upon inspection he found that a fuel line was leaking. He looked up to see if there were any Hyundai Technical Service Bulletins related to the issue. He found "Fuel Tube Replacement (Recall 227). Due to the recall we contacted the dealer Piazza Hyundai of Limerick (PA). The service representative (Jason) looked at the recall and stated our vehicle was not a part of the production line being recalled. All items in the recall were found on our car. We had our independent mechanic fix the fuel line. Prior to the repair the car was not in a drivable state.

While driving the vehicle the lights on the dash start to flash, stating that there is a Charging system warning. It says to pull over and not to drive. It becomes very difficult to brake, or steer, almost like the vehicle has lost power. It blew warm air and the check engine light also came on. This can be extremely dangerous if one was on the highway or at an intersection or any place where they needed to pull over to safety. My 12v battery was checked and found to be fine. I called multiple mechanics to come take a look at the vehicle and the codes that were read were P1B77, P1B96, P1B70, P0A0D. The 150 Amp fuse was said to be blown, and was replaced. Sometimes the car will start back up, and sometimes it won't. Currently, it's sitting in my yard. The engine and interior look pristine, but there is something going on with these vehicles that isn't being addressed. This car is dangerous and there are many, many, MANY people that I'm finding on Reddit, YouTube, and the Hyundai forums who are having the exact same issues. I unfortunately cannot afford to continue to keep hiring mechanics, nor to have it towed to the dealership, only for them to do what they are doing with countless other people. They do not seem to understand the issue either and are grasping at straws to replace expensive parts, only to have the issue reoccur. Something needs to be done about this before someone is killed.

My car has been at the dealer since 5/3 which i had an appointment for the TXXI engine failure and fuel pump 227 recalls. I was driving my lights all came on and the car decelerated and wouldn't speed up anymore the steering wheel also got tight.i just got oil change at the end of March and haven't been any long distances. I was told 2 days later that my car was being diagnosed it is now 5/10 and I'm still being told my car is being diagnosed with absolutely no update, they also refuse to give me a rental car or provide a out of house rental... They are making me pay out of pocket for rentals then can only post for reimbursement which isn't guaranteed after the work is done but cannot give me any type of word on even when the diagnostic will be done. I asked if they have any order to diagnosing like is it in order he said no i said so someone can bring their car in after mine and get completed before for same thing just depending on which the technician decides to do the advisor said yes candidly. I've been calling for updates and have not received anything other than the diagnosis is still not done after 7 days. I'm paying for a car that i don't have access to and it's not being expedited in order. When i dropped the car off they said it would take 4 days tops with are they starting my car then not finishing.

This fuel pump recall 227 was issued on May 2022 and I've yet to be able to make an appointment to get it fixed. The Hyundai of San Bruno I was finally able to reach said they'll call me back when the parts come in. That was almost a year ago and when you call their service department, you can't even leave a voicemail. On some occasions you can leave a voicemail, but it's never returned. This is a fuel pump hose, not a complicated part. They should have this part. This is unacceptable as this recall addresses a potential fire risk.

I was commuting home from work when suddenly there was smoke coming from under the hood and the vehicle completely stopped working in the middle of the road. It would not accelerate and I had to get help to move it into a parking lot. I had to get it towed to my home. The car will not start. If we turn the key to try to start it, the engine starts smoking.

Incident

Mar 12, 2023

After driving for about 45 minutes, car began to shake and make loud knocking noises, and the check engine and oil light both came on. After adding 3-4 quarts of oil in order to get to the destination, it seemed okay. After turning the car off, and back on, after about 15 minutes of driving the shaking, loud knocking noises and check engine light turned back on. At this point, the car was towed to a local mechanic. The mechanic noted that this was a problem with the engine and oil line and should be brought back to Hyundai because there is an active recall regarding this issue. Upon bringing the car to the Hyundai dealership, they agreed it was a recall issue and would fix it under the recall. Two days later we were informed from Hyundai that it would be $8,000 to replace the engine because the car is about 2,000 miles over the recall warranty and they will not make any exceptions. After calling Hyundai's corporate number, they agreed that it cannot be fixed under the recall warranty. They also confirmed that they never notified us regarding this recall. If we had known, we could have fixed this while it was under the mileage. The car is not drive-able and we are devastated by the lack of communication from Hyundai and refusal to fix this issue. There was no warning and while we are grateful nobody was hurt, this is extremely dangerous and we are now left without a car!!
