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.

I bought the vehicle 14 days ago and everything was going well until black smoke started to come out of the exhaust and it started to smell burnt. I brought a mechanic to my house and he told me that the engine had already died

I took my vehicle in to get the initial KSDS recall campaign updated (knock sensor). The car failed on my way home from the dealership and they scheduled me the next day to fix the problem (the acknowledged the knock sensor update caused the failure and is the that beginning step in obtaining a new engine from Hyundai. They then gave me a loaner car while my car was going to be repaired. I then recieve a call from the Hyundai service center about how my salvage title status excludes me from further repairs. I am then forced to drive my car home again with a failed engine. The sneaky way this is being done is horrific and on a massive scale. I was duped into getting the recalls from the letters sent out by Hyundai and at no point was there transparency about what would and did happen with my vehicle (and many others). No acknowledgement on how most if not all cars who get the update fail about 10 miles after driving it again, and lose power (I was on the highway in the far left lane). I was robbed of my ability to make an informed decision about my vehicle, this whole process is shrouded in secrecy from the consumer and I'm left holding the bag and the dangerous un drivable vehicle. I'm not sure how I can be cohersed from the manufacturer to let them fix their initial errors and be left with a non working car and expected to pay for the bill. There was no transparency about what I was signing up for, the ramifications and the safety hazards with the cars being statistically most likely to fail on the way home. What they are doing to me and many other people is dangerous and extremely wrong on many levels. When the engine failed I was extremely close to being rear ended and causing a large accident as it was full and fast moving traffic on the highway. I was fast acting and maneuvered properly and safely. Some will probably not be that lucky. There was no real warning, just a heavy thud and lose of power in tandum with the check engine light flashing (never has before

Today the vehicle was hesitant to start but did. After two stops I turned car off, went into a business. When I came out the car would start but would not go forward or backwards but rev up. I nearly slammed into a curb in the process. I have a video of this.

I own a 2017 hyundai veloster with roughly 122,000 miles on it, recently I got in my car to go to work, started the vehicle and exited my apartment complex onto a local road drove roughly a half mile to the on ramp for the highway, the car was just about up to its usual operating temperature when I accelerated down the on ramp and merged into traffic, at this time there were no warning lights, the engine temperature was normal, the car reached roughly 55/60mph and immediately lost power, pressing the gas pedal harder caused the car to lose more power and buck. At this time there were still no warning lights on the dash, the car slowed down to roughly 30/35mph presenting a significant danger to myself and other traffic as this was on a major highway with heavy amounts of traffic. It was approximately 4 miles to the next exit and the only safe place that I could exit the highway/ flow of traffic. The car was turned off and sat for roughly 5 minutes at which time I restarted the vehicle and drove it home on a local side road, the vehicle had no power and would not accelerate or maintain a speed above 30mph, at this time there were still no check engine lights on. A tow truck was called to haul the car to a local repair shop as the dealer had no openings for service, at the time the tow truck showed up to load up my car the vehicle was started breifly and a check engine light was now on, the local repair shop diagnosed the issue as a failed catalytic converter and the engine code as indicating inefficient emissions control readings on an 02 sensor. The repair shop could not come up with a reasonable answer as to how the catalytic converter had failed other than saying it had completely melted the material in the converter. The engine had no misfires, fuel issues, excessive oil consumption at this time and no engine codes were active or stored indicating any of theses issues. The catalytic converter failure is a major saftey issue that is happening on hyundai engines.

Purchased the car as a used vehicle in October 2023, dealer claimed to have changed the oil , in May the car we no longer running, I took it to a Hyundai dealership where they told me that I need a new engine because of oil consumption… This is something that should be included in the current class action lawsuit, the car is dangerous to drive as it will not stay running stalls in traffic, not to mention I’m out thousands of dollars due to an issue

Occasionally when traveling at speeds under 30 mph and you depress the accelerator the engine will hesitate to respond for several seconds.
