2015 Hyundai Veloster Engine Problems

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.)

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.

The contact owns a 2015 Hyundai Veloster. The contact stated that while driving at an undisclosed speed, the vehicle hesitated. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic who performed a tune-up on the vehicle. The contact stated that several days after the tune-up, the failure reoccurred. The contact stated that while the vehicle was stopped at a traffic light, the vehicle hesitated and sounded as if the vehicle was going to stall. The vehicle was taken back to the independent mechanic, who diagnosed that the engine was losing pressure and needed to be replaced. The vehicle was not repaired due to the cost. The contact stated that before the vehicle had the tune-up, the engine was consuming an excessive amount of engine oil. The contact had not noticed any oil stains on the ground. The check engine light was occasionally illuminated. The manufacturer was not made aware of the failure. The failure mileage was approximately 72,000.

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.

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.

The contact owns a 2015 Hyundai Veloster. The contact reported that oil was leaking out of the exhaust. The vehicle was sputtering and running rough while driving at various speeds, and hesitated while accelerating. The check engine warning light was illuminated. The vehicle was taken to the dealer, who was unable to diagnose the failure. The dealer informed the contact that metal shavings were found in the oil pan during the oil change. The contact stated that the Oxygen sensors and catalytic converter were replaced; however, the failure persisted. The vehicle was contacted and advised the contact to return the vehicle to the dealer. The manufacturer was not informed of the failure. The failure mileage was unknown.

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 NHTSA 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.

I HAVE BEEN TRYING FOR OVER A YEAR TO GET MY ENGINE REPLACED IT IS RECALL AND NO DEALER SHIP IN MACON GA OR MILLEDEGVILLE GA HAS DONE NOTHING BUT CHARGE ME UN NECESSARY MONEY.

MY CAR IS STILL STALLING, NO COMPRESSION,OIL CONSUMPTION NUMBER 198

my car is recall for connecting rod bearing failure hyundai gave us a extended warranty for this 15 years or 150,00 miles plus i have 20 year 200,00 mile warranty too my engine has oil consumption a quart every 2- 3 weeks been in the Hyundai shop October 2023 for oil around spark plugs jerking engine trying to stall i had my car tow they did a tune up charge me for towing and spark plugs said it was part of engine failure. next in 04/24 engine light came on compression has been getting worse over two years car tow was told catalytic converters were clogged which is not covered so there another bill on me which i think at 124 plus mileage was due to engine problems but Hyundai Corp denied this of course. They want me to drive the car until the engine light flashes in middle of nowhere all i want is my recall engine fixed so i will feel safe in my car there was a lawsuit on the connecting rod bearing failure RECENTLY nothing has been done i can't afford another car at my age

nothing has been done for the recall engine, Hyundai recall 198 which states damage engine can increase the risk of fire or engine stall increasing the risk of a crash. why is Hyundai selling cars that are recall for engines . as stated before oil consumption, jerks, no compression, going up hills is rough, cabin gets warmer than usual Hyundai Corp told me that the clogged catalytic converters were no cause by engine failure is this correct i have to pay for them. i have the recall for the brakes finally making a appt can you help me my engine is getting worse i'm afraid to drive it.

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.

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 NHTSA 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.

engine runs too lean had T/B and104898 MAss airflow and O2 sensors replaced less than a year ago still same problem also consuming too much oil,

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.

I bought this vehicle from a used car lot in February 2023, not 2022, and drove it under 3k miles; when I took it, it had 86k miles, and the check engine light came on. I took it to FRANK HYUNDAI, where, to this day, have not been able to help me; all this time, I, the consumer, had to chase down the repair guy assigned to my car and, only to be vaguely told it was sludge and metal shedding. It might be my misuse or neglect when I had driven the damn thing before even recommended servicing or an oil change was needed. I also called Hyundai Motors corporate, where a case manager suggested a goodwill repair, but nothing had been done. I would appreciate any help NHTSA could provide as there are campaigns on this model car with engine rod failures, and the damn extended warranty should apply to subsequent owners.

Engine had no oil, starting making a knocking noise.

99% sure the vehicle’s rod bearing is what is knocking

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

Rattling noise is occurring when accelerating and on cold start. This has been occurring for quite some time.

Rod bearing in the fourth piston is failing and there is an existing TSB for this problem on this year (2015) of Veloster however Hyundai is saying that it doesn't cover this engine model so we are going to be out $7,000 for a new engine. Seems like the engine is the same only difference is the turbo so seems like this model should be part of the TSB as well. The problem has been confirmed by a mechanic at his shop C&C automotive in Fayetteville AR
