2013 Hyundai Veloster: misfire or rough idle

Filed Apr 29, 2025 · Engine · WI

I was driving my vehicle and it began severely misfiring and stalled on me. I took it to the dealer and found there was damage to cylinder number 2 engine balance. After research I found there are many claims and complaints due to this type of issue. The likely cause is preignition caused by what Hyundai calls bad software. I recently purchase the vehicle and they say it was updated in July of 2024 and will not repair my vehicle as they say because of its age and mileage. That being said I’m at 120k mileage and work in the auto industry…. They is nothing that could cause valve burn outside of the known ignition issue with these cars. I have no problem paying for repairs due to my cause issues or normal wear and tear but a melted valve is caused by the know issues on these cars. I am looking for help working with Hyundai to get this issue fixed.

A connecting rod bearing failed in the engine leading to catastrophic engine failure with the connecting rod breaking through the wall of the engine block causing a hole and undriveable vehicle. According to my research, this issue has been recalled in adjacent model years (2015-2016) but not in my model year (2013) that has the same engine. This issue has already been confirmed in these engines, but Hyundai states my car is not included in the recall. This was a safety risk because the engine failure breached the engine wall which could have ignited engine oil and caused a fire. The engine may have also failed at a critical driving moment when acceleration was needed and stranded the car in an unsafe position. Yes, the problem was reproduced at the dealer's service center because the failure occurred while they were test driving my vehicle. Since the service center tech was the one driving the car when the incident occured, I do not know if there was a fire or not and the speed they were traveling, etc. The vehicle has been inspected by the dealer service center and confirmed that this is the issue that caused the problem. The dealer even suspected this was going to happen as they had foreknowledge of the issue occurring on other vehicles that had already been recalled for this issue. The only prior warning of this issue is that I had some misfires on the engine a few days before which is what prompted me to bring it in for service. The misfires temporarily illuminated the "check engine" light but then the light went back out again. I had no idea this minor issue would result in such a severe, catastrophic failure.

Vehicle is burning through oil without having oil light engaged. Vehicle is going through two quart + of oil every 3 weeks. Just added 2 quarts of oil 3 weeks ago when the car would not accelerate past 5mph and rough idled (this turned out to be caused by a different issue still being diagnosed), I added the oil as dip stick showed no oil on the stick. Light did not come on. Took to independent mechanic this week who stated I had no oil in the vehicle. Can not go 3 month/3000 miles for an oil change or the engine would be damaged. Have taken the vehicle several times to Valvoline who indicate no oil with no oil pressure light on, each time. This has been constant for 2 years. Each mechanic shop states the GDI engines are burning through oil. No oil leaks have been detected. This issue could result in serious engine damage.

Unknown. I was driving my car home after work and basically the engine blew a piston out of the side of the engine while going 20mph, was just driving normally them a loud boom sounded like I hit a pothole or something but their where no objects in the road. And in my review I seen a trail of oil and one the car stopped all the oil was dripping from the underneath the car. The car had been sending a check engine light/coil misfire. And from what I know the recall is for some type of misfire code. I got no help from the dealer as to why my engine blew up other than it was my fault I lost the car in a accident and don’t have it anymore but I put in 7,000-10,000 on a turbo system and refurbished engine. And I strongly believe it has something to do with the recall at hand But I had no choice at the time and the recall didn’t come to me till after I lost the car.

Unknown. Yesterday May, 19th we were driving when the check engine light started flashing, the car started runing rough, misfiring, and there was a burning smell. On top of that our car has been burning too much oil and gass. As of right now we have an appt to have it towed to, and have it serviced at our local Hyundai dealership in Racine, Wi for our 2013 Veloster turbo. Our issue is that there is a recall on later models for engine failures, for the very same symptoms, but not ours for some reason.

Hello, I believe there is an underlying issue with the veloster 2013 that hyundai has not addressed properly with their service campaign. I had received the service around 06/01/19 (I am not sure exactly when) and a year later have had the same exact problems this service was supposed to address. I have had engine stalls in the middle of the street near usc on a busy intersection and had to move the car by foot in fear of getting hit by another car. I've also had engine power issues that seem to have persisted. When this happened I took it into a mechanic to address the issue, their diagnosis was a bad coil pack for which they did a tune up (spark plugs, coil packs, oil filter). Shortly after the tune-up I had problems of the same misfiring issue where there would be no power to the engine and a slight knocking noise. I then took my car to hundai keyes mission hills to diagnose the problem this time and they said the same thing, bad coil pack. There have been known engine failures due to the ecu, and have read many anecdotal evidence that there is an issue with the ecu. I also believe this issue has caused my catalytic converter to fail prematurely as the misfires would send unburned fuel into the catalytic converter. I initially got in contact with a service manager at hyundai consumer affairs on feb 15th and he has finally called me today 03/15/19 after weeks of trying to get updates. The supervisor has deemed that this was out of warranty and that I would have to pay for it even after expressing my concerns that there might be an underlying issue that has not been resolved by the service campaign. This is a dangerous problem for other veloster owners. And I fear that my engine will fail in the future. Here is the service campaign. Report receipt date: mar 14, 2019 the federal safety agency campaign: 19v204000

I bought a 2013hyundai veloster in april of 2019 with in the first 2 days of having car it stopping accelerating an left me on the side of road. I had to car towed back to the dealer where the car was bought . After them looking in to the problem they ended up replacing the catalytic converter. The car ran fine for about another 5 to 6 months. Then one day bad rough idel rpms dropping when under acceleration after putting on code reader it turned out to be a misfire I then replace coil pack and spark plugs. The veloster ran fine for about 3 to 4 months this time. Now we are back to the car having issues today 7/11/20 loss of power under acceleration,rough idel,knocking sound coming from engine. I have contacted hyundai in the past on the 2013 ecu recall they did not want to honor there recall saying in order to look in to the problem I'd need to get it diagnosed through the dealer when I can simply use my owe code reader. It has been nothing but issues with this vehicle I bought with only 63000 miles this is frustrating is there anything that can be done for hyundai to honor there recall thank you .

Engine cylinder misfires . Even after changing spark plugs and coil packs. Especially when eco mode is off(in montion, accelerating) .when traction control cuts power seems to also attribute to misfiring and which has lead to unsettling idle.

Lag upon acceleration. Multiple cylinder misfires. All replaced and continue to misfire. To much oil being expelled through exhaust, regular oil change records and drive efficiency. Potentially ruining turbo as well as motor. Depleting mpg.
