I am reporting a safety-related engine defect involving sudden internal engine failure, excessive oil consumption, persistent bearing knock, and overheating of the catalytic converter. The vehicle repeatedly triggered Bank 1&2O2 sensor fault codes due to oil blow-by and thermal overload. A certified mechanic documented the engine is failing internally and that the cat. converter has been damaged as a direct result of engine defect. The failure pattern is consistent with known Hyundai engine defect investigations involving bearing wear, oil consumption, stalling, and fire risk. The overheating cat. converter presents a significant safety hazard, including potential engine seizure. I purchased the vehicle used in March 2025. I am the third owner. Despite maintaining the vehicle responsibly (Regular oil changes), the engine failure progressed rapidly. Hyundai Motor America has denied a goodwill repair solely on the basis of mileage, even though the defect clearly originated long before my ownership and aligns with previously identified safety-related engine issues. Additionally, Hyundai's records show that this vehicle had an engine-related recall active during prior ownership period; the recall was never performed by the Hyundai dealership that sold the vehicle to the previous owner. This raises concerns about improper recall handling and whether the defect should have been corrected before the vehicle was resold. Given the safety implications, the documented defect pattern, and the unresolved recall history, I am requesting the federal safety agency's review of this matter. The engine failure poses a serious safety risk; Hyundai's refusal to address a known defect, the vehicle is unsafe to operate. Timeline: 2014 Hatchett Hyundai West, KS 17,665 mi.; 2017-H.

What owners say
Excessive engine oil consumption causing fouled spark plugs engine stalling. Engine was replace due to defective rod bearings at 98 000 mile under warranty and recall. Engine now ha 130,000 miles piston rings have failed. Stalled on busy freeway almost causing mutual crash.I have an appointment at the Hyundai delership October 28th 2015. Hyundai replaced one defective engine with another.
Motor started knocking yesterday 4/8/25 which was immediately followed by multiple dash sensors for oil and battery. As I pulled over to get assistance at a Jiffy Lube, the car stalled and wasn’t drivable but they also confirmed that the car should not be driven for risk of blowing the engine. Will be taking my vehicle in for an evaluation as soon as I am able to get it towed for further inspection and diagnostics.
Spun rod bearings. Noticed that was the issue with play in piston doing a screwdriver test and noticing thru under the oil pan before tear down. Had to pry the bearing off with pliers and hit with a screwdriver to remove. I have plenty of photos and videos
Spontaneous rod knocking, hindered performance which in tern poor acceleration, which could become a safety risk especially when commuting on a freeway. High risk of motor vehicle accidents or could lead to a fatal incident if left stranded on major roadways and railroad crossings.
my car 2015 Hyundia Veloster has been under recall since 2021 for connecting rod failure in engine and oil leaking around spark plugs that could cause a fire plus what the other recall is. Hyundai Corp refuses to repair my car, it has ksds, oil consumption, refuse to do engine inspection, wanting to charge me for items related to a recall. my car as stated with you before eating oil, poor compression stalls knock loses power i recently had to pay 3200.00 for catalytic converters so i would have a car only to find out it could happen again due to recall number198. i need someone to help me get this resolve. why should have to replace my engine when it under recall and you can't sell your car due to that? i have been fighting Hyundai Corp for two years i had oil around my spark plugs in 2023, black spark plugs 2024
The contact owns a 2015 Hyundai Veloster. The contact stated that while driving at an undisclosed speed, there was an abnormal knocking sound and smoke coming from the engine compartment. The vehicle then lost motive power. The contact was able to pull over to the shoulder of the roadway, where the vehicle was able to be restarted. An unknown warning light was flashing before the vehicle had lost power; however, there were no warning lights illuminated once the vehicle was restarted. The vehicle was taken to the dealer, who was unable to duplicate the failure and had not provided the contact with a specific diagnostic report. The vehicle was not repaired. After investigating the failure, the contact related the failure to the federal safety agency Campaign Number: 20V746000 (Engine), but the VIN was not included. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 44,000.

The contact owns a 2015 Hyundai Veloster. The contact stated while driving at undisclosed speeds, the vehicle started to decelerate independently, and there was a ticking sound coming from the engine. The contact discovered the federal safety agency Campaign Number: 20V746000 (Engine). The vehicle was towed to the dealer; however, the failure could not be duplicated. The recall repair was not performed. The manufacturer was not made aware of the issue. The failure mileage was approximately 135,000.
HVAC system has failed twice, upon inspecting, connections are melted. This is a fire RISK. Fuses constantly blow. Check engine light constantly comes on and after having auto zone diagnose, issues include Power Train System (P2261), anti-lock brake system - Wheel Speed Sensor (all 4) show invalid/No Signal. Constant knocking noise under the engine which related to the Rod bearing recall. This car is a FIRE and SAFETY HAZARD waiting to happen. My outlets barely produce power, my lights flicker constantly, my battery has been replaced multiple times, as well as the HVAC once.
The car I bought in February in a used car lot was, per the salesperson, in excellent condition, had recently done oil changes, and had allegedly no failures. After less than 3k miles, I got stalled on the freeway with a knocking noise; Frank Hyundai mechanics diagnosed it with a CVV oil sensor red flag. I then paid for the repairs after getting denied from both my Hyundai warranty and my extended warranty. This was neglect when I drove that car for just a few months, like a weekend car, less than 3k miles. The car was still stalling on the freeway, shooting smoke, and the check engine light came on. I miraculously made it in one piece to work; however, the car had to be towed back to Frank Hyundai, where, to this day, they still have not been able to repair or precisely diagnose my vehicle, so I have been without my vehicle for almost a month and a half. I'm pretty sure I'm not the only one with this problem; I think it's unfair to pay for the past owner's negligence.
