2019 Hyundai Sonata problems

“The contact owns a 2019 Hyundai Sonata. The contact stated that while driving 55 MPH, the check engine warning light illuminated, and the vehicle went into LIMP Mode. The contact stated that the vehicle failed to accelerate above 58 MPH. The contact retrieved DTC: P1326 (Knock Sensor Detection System) at O'Reilly Auto Parts and stated that the knock sensor had previously been replaced. The failure mileage was approximately 90,000.”

“The vehicle consumes a gallon of oil weekly. The spark plugs are having to be replaced every three months. The Low beams have been replaced and are working but the headlights are completely out and flashes on the dash board. I have Hi beam’s only. There is an electrical issue with the vehicle and is very dangerous to drive with the oil leaks that are continuously happening.”

“The low-pressure fuel pump module assembly, located directly beneath the rear passenger seat cushion, experienced a plastic housing failure. A stress fracture on the upper plastic fuel outlet nipple caused raw liquid gasoline to actively weep and pool on top of the module inside the passenger cabin. This component is retained and available for inspection upon request. RISK TO SAFETY: Raw liquid gasoline pooling inside the interior passenger compartment creates an severe, immediate fire and explosion hazard. Additionally, vehicle occupants were exposed to toxic fuel vapors while driving. INSPECTION & DEALER CONFIRMATION: An authorized Hyundai dealership inspected the vehicle and confirmed raw fuel leaking at the top of the fuel pump module assembly. This exact module had previously been removed and disassembled during a 2024 manufacturer recall service to replace the internal fuel filter and tank seal. Stress applied to the plastic fittings during that recall service appears to have caused the plastic top-hat to fracture over time under line pressure. Hyundai Corporate was notified of the safety hazard and prior recall history, but refused assistance. WARNING…”

“I wanted to report the failure of my rear camera and/or the electrical circuit that is tied to it. It's my understanding that Hyundai has issued multiple recalls across different years/vehicles for issues in this area. My 2019 Sonata is NOT included in those current recalls. I was without my vehicle for a week and was charged over $1600 to repair. The issue was diagnosed and repaired by an independent mechanic. When they system failed numerous error lights/warning went off and continued to cycle thru (plus beeping). I wanted to report this in hopes of continued pressure on Hyundai to add this model/year to their recalls.”

“The air bag light suddenly illuminated when turning on my car. My car has around 60k miles. It was previously repaired a few times for a power steering faliure while driving making it hard to stear. I believe that this latest failure is due to a failure of the stearing wheel clock spring or another SRS module. failure.”

“The contact owns a 2019 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the vehicle experienced severe overheating and excessive oil consumption. The contact also stated that there was a misfire in the engine even though the spark plugs and ignition coils were replaced. Due to the failure, the vehicle could not be driven with the air conditioning activated. Additionally, the engine was knocking and shaking abnormally, causing an oil leak and a smoke odor due to the oil burning. The vehicle was taken to a dealer, where an engine replacement was recommended. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 140,000.”
