Attempted to pull out of our neighborhood and car check engine light as well as every other light came on on the dashboard. Car completely loss power and stalled in the middle of the road. Multiple attempts to re-start the car but would not start. Had mechanic check vehicle, originally pulled a code for fuel pump but when tested a few days later and at the fuel pump that code was gone. Checked everything could not find a reason it would not start. Called the Hyundai dealership and they said yeah your engine lost compression and probably has to be replaced but we can't tell you for sure until you bring it in and it will be $350 to tell you if that is the problem. I am having it taken in to see. The car VIN does not show as part of the 21v 301 recall on this site but is experiencing the exact issues listed in the recall. We will see. . .

I stood my 17 month old nephew up in the front passengers side floorboard of the 2012 hyundia voloster manual transmission with push start . I stepped out of the car on the passage side of the car the car was parked in first gear no one was on the driver's side . I bent over to get my shoes on and baby reached over and pushed the start button on the car the car should not have started since the clutch was not pressed in but unfortunately the car started and lunged forward being on a incline it was as if someone smashed on the gas pedal I ran with the car as far as I could but it was going so fast I could not get into the car to stop it I was drug trying to stop the car the car flew thru a fence , into the woods, down a steep hill then crossed a one lane road traveled up a hill thru another patch of woods before going up hill and hitting a tree all the while our nephew was not in a car seat the car was bouncing side to side when it went off road to cross a creek so I know the baby was thrown around in the car he had to of been that car was going so fast I was screaming in fear that he would not be alive when I made it to the car now the key was in my purse located in the passenger side floorboard where I stood the baby up at so when I reached the car the doors had automatically locked the car was still running and the baby was screaming I could not leave the baby to go get help so I tried to tell him to open the door but like I said he is 17 months old he didn't know what I was telling him to do and since the car went thru the fence it knocked the wiper blades off and the metal was going back and forth on the glass and it was so loud screeching back and forth and baby is screaming and I could not get to him and I know the screeching is scaring him even more so I reached up the pull the wipers away from the windshield and when I did baby leans on the door to see what I was doing and he hits the windows button and the windows came down just far enough to get it unlock.

After an update for a recall for brake issues, the dealership updated the knock sensor update without my consent. After the knock sensor software was installed, my 2012 Hyundai Veloster will not operate without going into protection mode. Hyundai states that they can not reverse the software update to make my vehicle operable again. This has already come up as a safety concern as my wife was on the interstate when the vehicle shut down in 70+ mph traffic.

My 2013 Hyundai Veloster (VIN: [xxx] ) has the known p1326 fault related to the theta ii engine defect. Despite a rod bearing test that passed, the engine now requires replacement, confirmed by the dealer, who quoted me $8,494. Hyundai refuses to assist, even though I am under the 150,000-mile extended warranty. This is a safety risk and fits the class-action defect criteria. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Abs, eps, check engine light appeared on dashboard then car’s steering wheel stiffed and car lost power. Vehicle’s hood smells burnt and has fumes come out after driving for 10-20minutes. My safety and my family’s was endangered as this happened while driving on the road. Not at a stop sign or a red traffic light but while driving. The dealer has refused to inspect/address the issue without having me paid close to $2,500. 00 for other repairs.

Vehicle info: 2013 Hyundai Veloster VIN: [xxx] odometer: 75,000 miles problem description: my check engine light began flashing and the vehicle entered limp mode. Diagnostic codes showed p1326 and u1103, which are linked to a known theta ii engine defect involving rod bearing failure. Hyundai issued a 15-year / 150,000-mile warranty extension and settled a class-action lawsuit to cover these failures. However, my request for coverage was denied due to “time in service” despite being well below the mileage limit (only 75k miles). This is a serious safety concern that may result in sudden engine failure. I am requesting that NHTSA investigate Hyundai's denial and handling of such cases information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2016 Hyundai Veloster. The contact stated that while driving 65 mph, the vehicle hesitated to respond while depressing the accelerator pedal, failed to exceed 45 mph and made an abnormal knocking sound. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic who referred the contact to the dealer. The vehicle was taken to a dealer where a bct (bearing clearance test) was performed, and the knock sensors were replaced; however, the failure recurred immediately while leaving dealer's parking lot. The vehicle was taken to two other independent mechanics, where the contact was informed that the engine needed to be replaced due to damage to the engine rod bearings. The vehicle was not repaired. The contact related the failure to NHTSA campaign number: 20v746000(engine); however, the VIN was not included in the recall. The manufacturer was notified of the failure and the contact was referred to the dealer for assistance. The failure mileage was approximately 79,700.

While driving under normal conditions at approximately 65 mph, the engine emitted a sudden “bang” and severe knock. Over the following week, the vehicle stalled several times. Inspection revealed one piston crown was chipped, which then scored the cylinder wall and caused an oil leak. No other pistons or bearings showed wear. This failure pattern is consistent with low?speed pre-ignition events documented in numerous online owner reports—many describing identical piston or rod breakage in 2013–2015 Veloster turbos under recall 19v204000, which addresses exactly this defect. The vehicle was partially disassembled for inspection, and Hyundai dealers have refused to perform the federally mandated recall 19v204000 remedy. Instead, they deceptively insist on treating this as a warranty work request—despite me having told them more than five times (on multiple recorded calls), in two portal updates, and via certified letters, that this is a safety recall issue, not a warranty claim. Their refusal has forced me to incur several thousand dollars worth of expenses and spend dozens of hours pursuing a remedy. Hyundai representatives have repeatedly argued that this engine malfunction may stem from previous accident damage. However, the vehicle’s only collisions occurred in June 2014, when it sustained moderate to severe front-end damage at approximately 1,000 miles and was subsequently repaired at a certified dealer, and in 2019, when it incurred rear-end damage under 30,000 miles. The piston-crown failure I experienced in 2024—at 90,000–95,000 miles—cannot be attributed to either of those incidents. Its nature and timing are fully consistent with low-speed pre-ignition, the exact defect addressed by recall 19v204000. An 11-page carfax report and full call?recordings are available upon request.

While driving home one late night, the engine completely locked up while driving causing the vehicle to come to a halt and left me stranded in the road. Got it off the road and eventually towed home where it was later inspected and found the engine bone dry of oil. There were no signs or indications there were any issues with oil leaking, etc. After much research, it's a commonly known issue with other Hyundai makes and models and even some of the same as mine in other years. This engine only has 100,000 miles on it. It just barely broke that mark before completely leaving me stranded. It's still an unresolved issue as no one wants to repair my car.

I am the second owner of a 2016 Hyundai Veloster base, purchased used at approximately 19,976 miles. Since then, the vehicle has experienced multiple major powertrain-related failures. At 49,196 miles, the first catalytic converter failed and was replaced. Later, both the engine and second catalytic converter were replaced by kearny mesa Hyundai, a certified Hyundai dealership in san diego, CA. When I brought the vehicle to kearny mesa Hyundai, there were no warning lights or active diagnostic trouble codes. However, the dealership’s service documentation stated that a p0420 code (catalyst system efficiency below threshold) was present — a code that was not active when I dropped off the vehicle, raising concerns about diagnostic accuracy or documentation. Now, at 61,982 miles, I brought the vehicle to Hyundai ontario due to delayed shifting and hesitation when accelerating. The dealership diagnosed internal transmission failure and quoted approximately $5,000 for repairs. There were no warning lights or codes detected, meaning this diagnosis is based solely on driving symptoms. The failure of two catalytic converters, the engine, and now the transmission — all within approximately 42,000 miles of ownership — raises serious concerns about the long-term reliability of this vehicle and possible manufacturing defects. The transmission symptoms pose a serious safety risk, especially when merging or accelerating into traffic. I am requesting that this vehicle be investigated for potential systemic issues affecting its powertrain components.

This car was recalled for a bad engine and because their computer would not throw off a code they refused to replace the bad engine. It has 60000 miles on it and has been well maintained. The rocker arms have gone bad and there are countless others who have the same issue that Hyundai refuses to address because now computer code was thrown off. They hide behind this to avoid replacing their bad engines.

On or about may 1, 2025, I was operating my 2013 Hyundai Veloster when flames were observed emanating from under the hood. I immediately pulled into the median and, upon opening the hood, observed an active fire beneath the plastic engine cover. I contacted 911. Before the fire department arrived, a passerby extinguished the flames with a fire extinguisher. Firefighters from a nearby station arrived shortly thereafter and fully doused the engine compartment. The vehicle was subsequently towed to a Hyundai dealership. At that time, I was aware of an active recall related to potential brake line issues that could result in an engine compartment fire. After the vehicle remained at the dealership for an extended period, I was informed that Hyundai motor America (“hma”) would send an inspector. Approximately 30 days later, I was contacted by hma’s corporate office and asked to provide documentation, including a copy of the title and insurance information. During this call, I was advised that while repair or replacement of the vehicle was unlikely, hma would “make me whole. ” shortly thereafter, I received written correspondence from hma stating that, following its review of the inspection results, documents, and other information, no product defect was identified as the cause of the incident. The letter concluded that hma would not accept responsibility and denied my request for assistance or compensation.

I have a 2020 Hyundai Veloster 2. 0l and their is a knocking noise coming for the engine for the piston haven’t been properly heated right and when I search the VIN up on here it come up as a different car in the picture.

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 is sluggish and loses power when it is taking off. It is like it is in slow mode. The other issue is that it uses lots of oil. I even had the dealership to repair the valve cover gasket. It should not use oil at the rate.

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.

The car stall when I'm driving.

The reason I am submitting this form is because my 2016 Veloster turbo has an open recall out for premature wear in the bottom end (bearings and rods) and my car has been experiencing the same problems. I have had the highest rated shop in my area to look at the wear directly and it is clear this is the problem with the engine. Despite this all attempts to contact dealers and the manufacture have resulted in those parties claiming my unit was not affected during the recall and therefore there is nothing they can do to help me. It is clear my engine is experiencing the exact problems detailed in the recall and I have treated this engine as well I can as I had knowledge of these problems, even still my engine is only a couple hundred miles away from blowing up completely and not running. When this car was bought I added a catch can to specifically help with the premature wear on the engine as well as never revving the engine to over 5,0000 rpms. As well to both of the previously mentioned conditions I have consistently changed the oil every 3,000 miles or before with the best oil and oil filter money can buy. Despite all of this and treating the car as well as I possibly could I still experienced significant terminal damage to my engine and I haven't even hit 99,000 miles yet. This whole experience has been awful and near impossible even for me someone who is very well equipped to handle car problems and I can't imagine how a regular family with basic car knowledge could ever navigate and handle this situation accordingly. All I am looking for is some type of help in any way to move forward my car is still running and driving but if I continue to drive it, it will most definitely blow up leaving me stranded. Thank you for your time.

I have a recall on the Hyundai 2015 Veloster for four years since the lawsuit that you told Hyundai corp to put lifetime warranty on defective cars thgey have done nothing to resolve the problem. My car again is broke down to oil around sparkplugs I went through the same problem in oct 2023 which they put a gasket on it and charge me 505. 00 dollars. Now they are making it hard to find a engine to replaced the manufactured defect engine in it. Debris in crankshaft and then sold which cause the connecting rod problem premature. I need my car and can't afford another please help me get this resolve.

The contact owns a 2017 Hyundai Veloster. The contact stated that on three separate occasions while driving at undisclosed speeds, the vehicle went into limp mode with the check engine warning light flashing on the instrument panel. The vehicle had been towed and driven to the dealer and an independent mechanic to be repaired. The contact was informed by the dealer and an independent mechanic that a knock sensor failure had caused the failure. The contact stated that the combustion chamber had been cleaned and the catalytic converter was replaced; however, the failure persisted. The contact also stated that the vehicle was consuming an excessive amount of engine oil. The manufacturer was not notified of the failure. The vehicle was not repaired and remained with the dealer. The failure mileage was approximately 100,000.

The contact owns a 2014 Hyundai Veloster. The contact stated while driving at an undisclosed speed, the contact noticed a extremely loud knocking sound that increased louder as the vehicle was being driven. The contact drove the vehicle to the shoulder of the road. The vehicle was towed to an independent mechanic, however the vehicle was not diagnosed or repaired. The vehicle was taken to another independent mechanic where it was diagnosed with a failed engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA hotline and report the failure. The failure mileage was approximately 98,000.

The component that failed is acceleration. He came from work at the frywed when he reduced the speed from 65 to 30 and no longer accelerated . . If an independent service had no warning or failure at that time they were detected.

The engine has a known issue with the port holes being too small to allow adequate oil flow, this has been addressed in the non turbo engines. Our Veloster had the same malfunction engine failure in which Hyundai is not covering and the dealership is doing a goodwill coverage of only 70% expense of engine only. When the engine throws a rod due to the malfunction it damages the turbo most times and they are requiring a full payment for that issue. Main focus is the engine when replaced has larger holes/ports and the engine can perform adequately. So as a consumer and owner we want to advise on this unbalance of coverage of the extended warranty. Especially since the turbo engine is identical just adding the turbo which it's performing at a higher rate.

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 engine is blown. The extended warranty offered by Hyundai does not cover the time period or mileage I've had deeming it useless. This is a serious problem and it should be addressed properly. I cannot drive this vehicle. I still owe on my loan. The warranty is not sufficient for the damages accrued regardless if I had signed up in time. This is dangerous, criminal and I'd like reimbursement.
