2014 Hyundai Santa Fe fuel/propulsion system problems

“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.”

“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. After the second white smoke through exhaust incident, the vehicle struggles, and often does not reach, 60 MPH; aligning with "Reduced power and/or hesitation" (case #2) in the recall campaign. 3. Exhaust Smoke: On two separate occasions, within a month, white smoke has been observed exiting the exhaust. Engine oil has been below 3/5…”

“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. She later called back and stated that the fuel pump was replaced but that the car was still leaking gas and would result in more diagnosis and repair fees up to $6,000 or more. I questioned the original diagnosis and she explained She would have to hand the matter over to Management. I spoke with Mgt. several times on the repair and mis diagnosis who…”

“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.”
