2025 Nissan Sentra

I purchased an Orange Nissan Sentra SR brand new on [XXX] with 27 miles on the odometer. The Nissan dealership was located in California. On [XXX] I saw a bubble, approximately 2" inches in diameter on the outside facing sidewall of the right front tire. At the time I saw the bubble, the car had approximately 8,775 miles on the odometer. The vehicle WAS NOT involved in any accident or DID NOT strike any large pot holes or other object that would cause the bubble on the tire. The tire is a manufactured by Hankook and it is part of the Kinergy GT series. Tire size is 215/45R18 89V. Bubble can be seen directly over the tire size on the sidewall (see pictures). This is an extremely serious condition. It can result in catastrophic tire failure causing the driver to lose control of the vehicle and resulting in potential injury or death. I took the vehicle to the Nissan dealership where I bought it and they WOULD NOT cover it under my 36 month new car warranty. I had to pay $339.54 to replace the defective tire. This was one of two similar vehicles I bought on the same day. The other vehicle also had the same bubbling on the exact same spot on the tire (NHTSA complaint #[XXX]) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2025 Nissan purchased new May 2025 came with Firestone FT140 P 205 / 60 R 16 I started noticing a very slight vibration in rear tire at 42 mph around September 5600 miles On Sept 20, 2025 I took car on trip for several hundred miles at speeds over 70 mph. The car has developed a much more noticed vibration above 50 mph. On Sept. 22 I had tires checked for failure. Local tire store who sells Firestone told me both rear tires was out of round. This store could not warranty my tires, they said they only sold them. I would have to find a real dealer. I called Firestone # listed in my Nissan warranty book 1 800 847 3272 I gave them my Zip Code and problem, I was advised to find real dealer on compter my self. I found a real service dealer 55 miles away, I called them they had none in stock. They found dealer in Clarksville TN. 150 miles away for me suggested I should go there for fast service. I have spent 7 hours today on phone and driving to many dealers sell Firestone tires around Somerset, Ky I have defective tires and Firestone company could care less.

I bought a brand new 2025 Nissan Sentra SV Premium which included 17" wheels (only found on the SV Premium Package) with Michelin Primacy A/S size 215/50 R17 (original equipment). I began noticing some safety issues while driving straight out of the dealership. While driving on diamond ground concrete roads (rain grooved roads) on Interstate highways, the vehicle wobbles uncontrollable, to the point that I feel that I am about to lose control of the vehicle. I have to bring the vehicle to an unsafe low speed to control the vehicle. It seems like if the tread pattern from the tires locks into the grooves on the roads, and causes each tire to wobble the car wildly in different directions, which is absolutely terrifying at high speeds. I took the car back to the dealership with about 500 miles; they determined that the issue was rather from the tires and not from the vehicle.
