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 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.

I was driving on 8 east freeway when all of a sudden my car lost complete power. Engine light flashing, and couldn't pick up any speed. The truck in back of me almost hit me cause my car wouldn't go. Prior to this incident, my car was and has been working perfectly. . My mom had it towed back home and got a mechanic to check the code and it gave a P1326 code which is exact code for a previous recall on these cars. I contacted Hyundai Corporate and the rep told me to take it into a Hyundai dealership to get repaired but to mention that campaign 966 was performed on the car already. Which was to prevent the p1326 recall from happening. And clearly it didn't.

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.

About 2 years ago, my Veloster suddenly started using oil and began knocking. No check engine light or other indicators came on. I had it inspected by a mechanic who confirmed that there was a problem in the lower half of the motor and it would have to be replaced. I was aware that other Veloster owners had been experiencing the same issue. I found recall spawned by a class-action which extended the engine's warranty to 15 years and 150,000 miles, but the website said my Veloster was not covered by the recall. I called Hyundai and they also said that my Veloster was not covered by the recall. I was very frustrated. People I know that sell Hyundai vehicles remained hopeful that Hyundai would come around and recall my car too, but I do not think that is going to happen since it has been nearly 2 years now. I have a 2016 Hyundai Veloster R-Spec (which is a turbo model) and it has the same engine as other turbo models that were recalled. I am very frustrated that this issue is widely known and Hyundai seems to have gotten away with creating a vehicle that's longevity is subpar from any I have ever owned. It recently dawned on me to ask AI for help and it recommended I contact and you, the federal safety agency, so at the very least it is documented and patterns can be seen where this problem continues to occur with vehicles that were not part of the recall. I was very particular and admit about the maintenance on my Veloster. There is no reason that this car should be scrapped after experiencing a detrimental engine failure less than 7 years and 125,000 miles from when it was purchased brand new. I still have the car, which has been sitting in my driveway since before I had it towed to the mechanic about the engine problems.
