Open the full vehicle complaint log (all categories)Both Michelin 225/40 ZR 19 Pilot Sport 4S front tires had severe "chunking", or tread peeling, on them after only 8,000 miles. Atlantic Tire (Bayamon, Puerto Rico), the sole distributor and service center of Michelin in Puerto Rico, informed me that approximately 30 other Genesis G70's had recently made warranty claims regarding the front tires with severe "chunking". They informed me not to drive the vehicle until the tires are replaced.
On or about May 2022, and after on 8,000 miles driven, noticed severe "chunking", or tread peeling, on both front tires of my 2020 Genesis G70 purchased October 2020 from Genesis Puerto Rico, located at Plaza Las Americas, San Juan, Puerto Rico. The tread on both tires was coming apart to the point where you could see the metal underneath the treads. Driving this vehicle at high speeds without noticing the defect could have resulted in a blown tire and a potentially serious accident. By the time I noticed the issue, it was already at a relatively severe state, thus the onset of the symptoms is unknown, however likely sometime 2021. I took the car to the dealership. They referred me to a third party tire distributor (Atlantic Tires, Bayamon, Puerto Rico). This third party distributor indicated that approximately 30 different Genesis G70's had recently made warranty claims with the same severe chunking on both front tires. They believe all the tires in that lot purchased for the Genesis G70's have the same manufacturer's defect. The third party tire distributor confirmed this to be a defect of the tire advised me not to drive the vehicle anymore until replacing the tires. This is in San Juan, Puerto Rico, there is only one Genesis dealership on the whole island, thus all the G70's with the defect were sold from that one location. The dealership has also been aware of the defect and has neglected to inform the potentially affected customers and/or report this safety defect to the NHTSA. My girlfriend primarily drives the vehicle and she would never have noticed the tire damage. The tires in question are Michelin tires, however, Michelin does not have formal representation in Puerto Rico and Atlantic Tire serves as their distributor in Puerto Rico.
