“I was traveling on an interstate going home from work. My speed was approximately 65mph. I noticed traffic slowing up ahead. I began to drop my speed (cost down), as I was approaching the traffic the car in front of me was applying their brakes; I had already began to apply mine. I was applying more pressure to my brakes to slow down more as the person in front of me began to slow more quickly. The person in front of me then had to slam their brakes on and I was not able to stop in time to avoid collision with the car in front of me. That driver did not come in contact with any other vehicle. The impact was at approximately 50mph. I was then very quickly hit from behind by the car behind me. The vehicle behind me hit of center and more on the right back corner of my car. My vehicle sustained significant front-end damage; the hood was folded, the grill was gone, the radiator was pushed back. As I looked up after the impact and saw my hood folded I then noticed that my air bag had not gone off. How could the air bag have not gone off in an impact such as that. My safety was compromised by the possibility of hitting the steering wheel or worse such as impacting…”

“The water pump on my 2016 Toyota Highlander XLE disintegrated while I was driving in heavy traffic. The pulley came loose from the water pump shaft. I have the water pump. Our safety was at risk because this happen in heavy traffic and it could have effected my control of the vehicle if it had came off completely. The pulley was wedge between the wheel well and fame. I sent a claim to Toyota and it was rejected due to the vehicle be out of warranty. I'm saying this is a manufacturing defect. No warning before it happen.”

Tires

7 reports
“**Nature of Safety Defect Within 13,000 miles of normal mixed highway and light off-road use on a Toyota Highland, one tire developed a sidewall bubble and all four tires exhibited extreme and uneven tread wear—far below the advertised 50,000-mile treadwear warranty. The remaining tread depth on all four tires is already under 2/32" in multiple locations, with severe cupping and feathering that makes the vehicle vibrate violently above 50 mph and causes unpredictable handling, especially in wet & snowconditions. These conditions render the tires objectively dangerous and unfit for continued highway or street use. Manufacturer Response Pirelli warranty claim #2194927 was summarily denied as “impact damage” with no physical inspection. Pirelli has refused any prorated adjustment, replacement, or refund, and has kept possession of the failed tire. On November 17, 2025, Pirelli Consumer Affairs closed the case stating: “Pirelli considers this claim to be closed and will not take any further action regarding the claim or the subject tires.” Request to NHTSA I am asking the National Highway Traffic Safety Administration to open a formal defect investigation into the…”
