Hyundai Veloster loss of power problems

Filed Jun 8, 2026 · Engine · TN

2016 Hyundai Veloster with 1.6L Gamma engine experienced repeat catastrophic engine failure consistent with the federal safety agency Recall 20V746000 / Hyundai Recall 198 for connecting rod bearing failure. Failure #1: At 124,036 miles, engine developed loud knocking noise increasing with RPM, check engine light, and DTCs P0300 (random misfire) + P0303 (cylinder 3 misfire). Dealer repair order documented "broken intake valve on cylinder 3." Engine was replaced at my expense because Hyundai stated VIN was not covered under Recall 198, despite failure mode matching the recall. Failure #2: Hyundai replacement engine failed at 164,410 miles (40,374 miles on replacement engine). Identical symptoms returned: loud metallic knock that increases with RPM, same DTCs P0300/P0303, misfire cylinder 3. Vehicle is currently inoperable. Safety Concern: the federal safety agency Recall 20V746 states connecting rod bearings "may wear prematurely, which over time can result in engine damage" and "can increase the risk of a fire." Both of my engines suffered catastrophic internal damage at ∼40k-50k mile intervals with identical codes and cylinder 3 failure. A broken intake valve is engine damage directly caused by bearing wear allowing piston-to-valve contact. This is a pattern defect. My VIN was excluded from the recall, yet suffered the exact failure twice. The replacement engine supplied by Hyundai had the same defect. This presents a safety risk of sudden engine stall, loss of power, or fire while driving. Requested Action: Investigation into why VINs experiencing the exact failure mode are excluded from Recall 20V746, and assistance obtaining remedy from Hyundai.

I was driving down the highway when I lost all power to my engine and had to coast off and exit. Prior to the incident there was no indication of a problem. White smoke began coming out of my exhaust. I brought the car to a dealership and they told me that I would need a timing job and a new turbo. They said that my car was starved for oil, regular maintenance had been kept up with on the vehicle.

I was driving on the highway when suddenly the car lost power and the engine light started flashing. I was able to coast into a gas station. The car would no longer start and I was stranded. The next day, we drove back to where the car was stranded and attempted to get it started again, but we were unsuccessful. We had the car towed to a mechanic shop where we were told that the entire engine was blown and needed to be replaced. We had the car towed to the local Hyundai service center so they could inspect the engine. We discovered that the make, model, and year of our Veloster had been subject to an engine recall and these cars were given an extended warranty to 15 years/150,000 miles. Hyundai inspected the engine and refused to provide assistance under the extended warranty/recall. Replacement of the engine is going to cost close to $10,000.

Incident Description: I purchased a 2016 Hyundai Veloster (VIN: KMHTC6ADXGU255844) in May 2025. Shortly after purchase, the vehicle began exhibiting serious mechanical issues, including engine knocking, excessive oil consumption, stalling, misfiring, and loss of power. Despite these ongoing issues, the vehicle is listed as having Recall 198 completed. However, the symptoms associated with that recall continued and progressively worsened. The vehicle ultimately stalled in traffic while I was making a turn, resulting in an accident. In a separate incident, after exiting the vehicle and believing it to be in PARK, the vehicle moved unexpectedly and ran over me, causing serious physical injuries including fractures. Prior to these incidents, the vehicle had ongoing mechanical issues that were not properly resolved. The vehicle also required repeated jump-starts and became unreliable to operate. Additionally, there are discrepancies in the service records. The vehicle was towed to a dealership on or about June 8, 2025 and remained there until approximately July 15, 2025. However, the documentation provided reflects only a limited number of service days and consolidates multiple visits into a single summary. Due to these inconsistencies and the continued presence of failure symptoms, I am unable to verify that recall-related repairs were properly performed. These incidents raise serious concerns about engine failure and possible unintended vehicle movement, both of which present significant safety risks.

The engine failed due to suspected rod bearing failure related to Hyundai’s known rod bearing recall issue. The vehicle exhibited a flashing check engine light with diagnostic trouble code P1326, knocking noises, metal debris found in the oil control solenoid, and subsequent secondary damage to the catalytic converter. The engine has not been opened by the Hyundai dealership despite these indicators. The vehicle and affected components are available for inspection upon request. The engine condition poses a serious safety risk. An independent mechanic advised that the rod bearing issue presents a fire hazard and stated the vehicle should not be driven due to the risk of engine failure, fire, loss of life, loss of power while driving. A sudden engine failure or fire could endanger the driver, passengers, and other motorists. Yes. The Hyundai dealership documented secondary engine damage but failed to perform the required open-engine rod bearing clearance test despite recall-related symptoms. An independent mechanic confirmed the issue is consistent with rod bearing failure and advised that the vehicle is unsafe to drive. The vehicle was inspected by an authorized Hyundai dealership and reviewed by Hyundai corporate. Hyundai corporate relied solely on the dealership’s incomplete inspection and denied further investigation or goodwill repair. The vehicle has also been inspected by an independent mechanic who identified the rod bearing issue as a safety hazard. Yes. Prior to the failure, the vehicle experienced a flashing check engine light and stored diagnostic code P1326. The engine produced knocking noises and showed signs of internal metal debris and secondary damages. The absence of early warning indicators prevented earlier detection. However, the extent of internal metal debris and secondary component damage demonstrates a progressive engine failure consistent with known rod bearing defects, rather than a sudden event after the warranty threshold.

As I was driving to work one day my 2016 Veloster suddenly lost power on the expressway at expressway speeds. Now that in itself is very dangerous seeing as how there were big rigs around me. Luckily I managed to make it off of the expressway traveling slower than I turtle.i was almost rear ended on various occasions. I parked right away and left to work. I came back later that day and cranked her over and it started,but now with the check engine light blinking. So I attempted to drive it a little and it worked but now I've come to find out that it is in protect mode.I took it to my local Hyundai dealership (Hyundai of pharr) in pharr Texas and was told that Hyundai would not honor their extended warranty because whatever is wrong with it is not covered according to them. So a while back there was a class action lawsuit in California against the Hyundai Corporation of which I was a part of. When it was time for settlement I had a choice of monetary gain or and overly extended warranty on my 2016 Veloster that covered engine and transmission for I believe was 10 more years. So I chose the warranty but Hyundai still won't cover it. I guess I have to wait for my car to catch on fire before they submit the warranty and even then they will blame something else. So here I am,telling my story.

On March 2024, I had my veloster towed to a certified Hyundai service dealer because it suddenly began losing power, the oil light came on, the engine light flickered, and it began making a whining noise, and then the engine died and wouldn’t crank again. It took them weeks to diagnose it, and they told me the turbo was out in it, and quoted me an absurd amount to replace it. I had the turbo replaced, as well as some gaskets, the coils and spark plugs. It ran fine after that until June 2025 when the oil and check engine light came on and the engine died again while we were coming home from a vacation, 2 hours south of where we live in a tiny town that had no dealership or rental company within 100 miles. We found a small mechanic who said it needed a lower fuel pump. He put one in it and we got back on the road, but it still wasn’t running as well as it should. It don’t have quite as much power, but no dash lights came on. When I got home I took it to another local certified Hyundai service dealer, who said it needed new coils and spark plugs again, so they replaced them. Again it ran fine for a while until the day after thanksgiving this year, 11/25, when the oil light came on again at the end of my road. I took it to another local certified auto parts store who read the codes and found no suggested fix. No certified dealers were open that day, so I took it to Pep Boys where the engine light came on when I pulled in, and who said they thought it needed new timing solenoids, and put them in it. When they finished, they drove it and told me they felt like the turbo was going out and advised I take it to the dealer again. I had it towed to a certified Hyundai service dealer on Monday 12/01/25. They diagnosed it as needing a new turbo (again), a lower oil pan, and an oil switch. Quoted $3550. Over a week later today they told me that after putting it all in and tiring it on that the oil light came back on. They have now diagnosed it as needing an oil pump.

The contact owns a 2016 Hyundai Veloster. While the contact’s wife was driving at an undisclosed speed, the vehicle suddenly lost power, with the check engine warning light illuminated. The contact stated that the vehicle then stalled at a stoplight. The vehicle was restarted and immediately driven to the local dealer, who diagnosed the vehicle and determined that the engine compression was abnormal and advised the contact that the engine needed to be replaced. The vehicle was not repaired. The contact stated that while at the dealer, the service and diagnostic guidelines were not followed regarding the federal safety agency Action Number: EA21003 (ENGINE), and the coverage was denied. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 125,367.

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...

The 2017 Hyundai Veloster- Value edition is a Lemon straight from the manufacturer. I purchased mine in July of 2024 with 27,000 miles. When I test drove it I questioned the clicking noises that could be heard while switching gears along with minor "shuddering" at acceleration. I was informed by gentleman at Dealer that it was a normal characteristic of owning a DCT vehicle. One year later 7/2025 I have been experiencing more intense issues with clutch/transmission. I have a great loss of power at acceleration, it will stay bogged at 1,000-1,500 RPM'S before it engages and revs with a jolt forward. It is unsafe to pull out or lane change on highway. It also is shuddering upon every acceleration from a dead stop. The clicking noises are now accompanied by clicking noises any time it shift gears. I get an intermittent smell of something burning. It is DEFINITELY UNSAFE to drive in any temperature above 75° due to the vehicle not being able to get out of its own way. All issues are intensified. I brought the vehicle to Hyundai service center and all that was recommended was a coolant flush and Dual Clutch Transmission service, which I paid to have done. I am not the original owner so any manufacturer warranty is out the window. Any research done by consumer will show pages and pages of complaints about the 2017 Veloster and DCT problems. Hyundai NEEDS TO MAKE GOOD on the unsafe garbage they sold us! Let me inform you that the vehicle I am currently making this complaint about has less than 48,000 miles today 7/9/2025
