Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.

Tire size: 225/4R18 88W Code 2119 indicates manufacture on 21st week of 2019. Factory original equipment on a 2020 Hyundai Elantra GT (N-Line). At the dealer for an unrelated service at approximately 37,000 miles. Tech noticed cracking on sidewall of all original tires. Suspects it is dry rot. There is a previous recall for these tires in a different size from 2015, but it appears the issue has not been resolved. I've attached a photo as an one example of the cracking. All original tires have multiple cracks like this along the sidewall.
My 2020 Hyundai Elantra stalled on me in the middle of driving it. Only check engine light was on. Had an oil change three months prior to it stalling and not wanting to accelerate. Made an appointment with dealership, they stated it would be fine to drive for another month and a half when they were able to get my vehicle in to look at it. Spoke with guy on phone said there was no recalls, which was a lie. Because last year it had a campaign opened on it that i knew absolutely nothing about, on top of the three recalls on it. My car did not make it in time for the appointment. The engine blew up even though it had another oil change a week before. Dealership wants to blame me. Hyundai National also refuses to accept that it is something malfunctioned bad in the engine that is a safety hazard. I believe the piston rings were bad. Theyd rather blame me because i went over my miles for an oil change the first year i bought the car brand new. Also it had a recall when i bought the car. T
Had an oil change in March. By June the car stalled in the middle of the street. Restarted it and was difficult to accelerate. Made appt with dealership, couldnt get me in until two months later. Continued having problems car needed more oil and did oil change in July. Continued to drive and it blew a hole in engine. Which is crazy because it had new oil in it. March and july had oil changes. Hyandai is refusing to use any of my warranties and refuses to pay for it. Its a 2020 Elantra. I bought it September of 2020. First oil change was October of 2021, Second March of 2022. Dealership wants to blame me for car malfunction. THE CONSUMER REQUESTED INFORMATION ABOUT RECALL REPAIRS.
