2014 Hyundai Sonata fuel system problems

Filed Oct 15, 2026 · Engine, Fuel system · NY

Summary of Event: This vehicle was brought to an authorized Hyundai dealership for a mandatory safety recall engine replacement under the Theta II Engine Recall Campaign. The dealership successfully installed a replacement engine provided by the manufacturer. However, the dealership and Hyundai Motor America are now refusing to return the vehicle to me in a functional, safe condition. Safety Hazard & Defect: The dealership states that the replacement engine shipped by Hyundai is mechanically and physically incompatible with the vehicle's original, factory-installed high-pressure fuel pump (HPFP). In an official written correspondence from a Hyundai Motor America Corporate Case Manager, Hyundai explicitly documented that: "dealership stated that it is not safe to drive the vehicle with old fuel pump." Despite acknowledging that the vehicle is now in an "unsafe to drive" condition due to the mismatched replacement parts provided by the manufacturer, Hyundai Corporate and the dealership are refusing to complete the safety recall remedy unless I pay $1,500 out-of-pocket for a new, compatible fuel pump.

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 the federal safety agency 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 the federal safety agency 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.
