Service brakes

2 reports1 crash
“On [XXX] I was driving on [XXX] and was approaching my exit ramp and applied my brakes to slow down for the exit. My car began shaking and the brakes were vibrating very badly and not slowing down. I was either going to slam into the truck in front of me, or swerve and hit the highway retaining wall, which I ended up avoiding the truck and hitting the wall at 24 mph and my airbag didn't deploy. The vehicle was towed to a collision center and I submitted a case against Toyota that is still under review. No warning lamps, lights or sensors went off and the road was dry and no hazards on the road involved. Simply put, I applied my brakes and they failed which put me in severe risk of a big car crash and if I hadn't swerved and hit the wall it would of caused a larger accident. Toyota Case # [XXX] Toyota Customer Service Phone Number: 1-800-331-4331 Date of Incident: [XXX] Date of Toyota Inspection: 4/10/2025”

Tether, lower anchor (on car seat or vehicle)

1 report
“I purchased two of these car seats at Walmart. The worked fine until the girls grew enough to sit forward facing. The method of snaking the latch strap around these makes it impossible to properly tighten. The seats remain loose and cannot be safely used.
