2015 Hyundai Veloster: engine stalls while driving

Filed Apr 29, 2026 · Engine · IN

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.

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.

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.
