2015 Hyundai Veloster Engine Problems

2015 Hyundai Veloster Turbo (original owner). The vehicle has three severe safety defects: TRUNK/HATCH LATCH FAILURE: The hatchback lift support/latch fails, refusing to stay open. It unexpectedly fell, which has caused repeated, severe impacts to my head and neck, resulting in an injury requiring surgery. I must manually prop it open with a mini ball to load cargo. ENGINE & TURBO FAILURE / OIL CONSUMPTION: History of engine acceleration issues and turbo failures since 4,000 miles. At 44,000 miles, the turbo completely failed, the car started to whine, then rattle, and completely turned off. Dealer (Hyundai Escondido) forced a $2,200 out-of-pocket replacement despite being under warranty, citing a lack of at-home oil change receipts. The vehicle now has a documented, rapid oil leak and excessive consumption issue that the dealer refuses to repair, despite being reported prior to warranty expiration. SEAT BELTS: The front and rear seat belt latches are malfunctioning, intermittently releasing on their own, failing to release properly, or failing to latch securely, compromising the safety of a [XXX] passenger.

Incident

Dec 10, 2024

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 NHTSA'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.

I took my car to Gilroy Hyundai November 11, 2025 at 10:30 a.m. because my engine was not running normal, it shook lightly while driving at an incline and the engine light would not shut off. they charged me $284.99 to tell me what needed to be fixed, engine was not looked per Ernesto Garcia. Ernest told me they go by mileage, not actually checking the engine. He also stated that the mechanic drove it and it was fine. December 28, I was driving from Chico, CA back home to Morgan Hill, CA and the car shook and just died and left me on the side of Highway 505 Winters/San Francisco. I had it towed to Moorehead Automotive in Fairfield, CA and they said this car needs a new engine. I still owe 7,000.00 on this car and have had trouble with both Hyundai and Power (the additional insurance I purchased when i bought this car.)

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.

I noticed the engine was losing oil constantly and the exhaust was emitting black smoke often, I had to refill the oil about once a month, eventually the car broke down and took it to a Hyundai dealership. They said they needed to perform a leakdown/compression test on the car, and $585 to perform a diagnostic. Then they said the leak down/compression test showed the exhaust valves had broken and they would need to do a long block replacement. Also mentioned they needed to have Hyundai allow them to release that long block as it is part of a recall on other vehicles. Later was told Hyundai did not approve it under the warranty.

This has happened on 4 different occasions. I'm on the highway and my speedometer slams to zero and everything involving the brakes lights up in my dash. The car continues to drive but it's pretty worrisome as I drive 70mph around alot of traffic. I have been able to pull over every time but it's still beyond unacceptable. I've had my Veloster a little under a year and I don't know if the other recall involving the motor being replaced was taken care of. It was a recall associated with my VIN. I have a video of it happening but for some reason I try to upload it on the app and it won't allow me to. It is the proper format.

I was on the highway and looked at my speedometer and the mph was at 0. The abs and the brake light warnings came on and I couldn't accelerate and hardly brake. I pulled to the shoulder immediately. Took a couple hundred feet to finally stop. It was a very scary moment thinking my brakes have gone. I put it in park waited a moment turned it off... waited about 5 mins and it turned over just wanted to get it home
