The contact owns a 2014 Hyundai Santa Fe. The contact stated that while his daughter was driving at an undisclosed speed, she smelled a strong gasoline odor. There was no warning light illuminated. The contact's daughter veered to the side of the road and noticed that gasoline was leaking from the fuel pump location. The vehicle was towed to the dealer, where it was diagnosed that the fuel pump hose was leaking, and the fuel pump and hose needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The manufacturer informed the contact that the VIN was not included in NHTSA Campaign Number: 18V934000 (Engine, Fuel System, Gasoline). The failure mileage was approximately 110,000. The VIN was unavailable.
The dealer has confirmed that my 2014 Hyundai Santa Fe has an oil consumption issue. This results in the car randomly losing power from the accelerator while driving. You can push the accelerator all the way down to the floor and there is no power in the engine. The car then slows down drastically which results in potential car crashes from behind since there is no warning to the driver or to drivers of other cars. My car started having this issue in July 2021 when it had about 129,000 miles on it. It took Hyundai until late 2022 to determine the issue and deny responsibility for it. The attached documents do not include the multiple times that I had to bring the car in every 1000 miles to check the oil (they didn't document that). They said it would cost me $21,575 to fix the engine which is almost as much as a new car would cost! …
I Recently, experienced a sudden and alarming incident with my car. Out of nowhere, the car began leaking gas, which resulted in a fire. Prior to this incident, the car was in perfect working condition, and there were no signs of any issues or malfunctions. It was a completely unexpected and unfortunate event that posed a significant danger. The vehicle was towed to Hyundai Dealership of Myrtle Beach, SC in August. The service agent explained that the vehicle technician would diagnosed the issue that she would call me back with plans and pricing. She shortly called back and stated that the diagnosis was a fuel line and that it needed to be replaced, that the part was approx. $200.00 for the part and after labor totaling approx. $1025. This was agreed and plans were made for me to pick my vehicle up by 3:00pm. …
My 2014 Hyundai Sonata is subject to the recall campaign for the 2.0L and 2.4L Gasoline Direct Injection (GDI) engines. Since June 24, 2024, the vehicle has exhibited multiple issues: 1. Check Engine Light: The check engine light is continuously on and blinking, signaling that the vehicle is unsafe to drive. Diagnostic codes retrieved include P0140 (O2 Circuit), P0172 (System Too Rich), and P0126 (Knock Sensor Circuit). While the P0126 code pertains to the knock sensor, there has been no definitive diagnosis to determine if the issue is isolated to the sensor or indicative of a deeper engine problem. 2. Engine Power Issue: The car experiences jolts and kicks back during acceleration, along with intermittent lack of power. Furthermore, an independent mechanic performed some tests on the engine, determining that it runs too rich. …
While driving normally, suddenly the vehicle will jolt and the RPMs go down to zero despite the vehicle still moving. Even with the gas pedal pushed down to the floor, and being able to hear the engine 'vrooming', the vehicle will not increase speed. It is extremely dangerous to not be able to speed up when on a highway or interstate. The check engine light does not come on, the diagnostic at the dealership does not throw any codes and the issue is intermittent so no one knows how to fix it since they can't duplicate the problem on demand. Usually turning the car off and on will 'fix' the problem until it happens again out of nowhere. The vehicle is extremely unsafe; this has been happening on and off for months. We do have videos of this occurring; no one at the dealership or any friends who are mechanics have any idea of what is wrong.
There was a recall on my vehicle for the Knock Sensor. In 04/2019 this was fixed at the Stockton, Ca. Dealership. My car only has 69,654 miles on it. On 01/14/2023 my check engine light came on and my car started sputtering and cutting out. I took it back to the dealership first thing today, 01/16/2023. They said the Knock Sensor is out and will cost me $995.00 to fix. They said the part that was replaced 4/2019 only has a one year guarantee. I believe this is a poor quality part or vehicle defect.
Car not shifting correctly. No power. Could not gain speed to merge into traffic. Was intermittent for months finally the engine light came on. My mechanics diagnostic showed it was the turbo charger. There is a service bulletin 22-22-EM-004H
The engine has been running rough for awhile and emissions light came on. My car was having problems accelerating, 2 years ago the light came on but didn't stay on so the dealer couldn't diagnose problem.
