What 2024 Infiniti QX80 owners say
Most recent owner complaints, unedited.
Back window shattered for no reason. Vehicle parked on property and was fine when we came home last night in another vehicle and parked behind it. Online found out this has been happening where the back window spontaneous combustion for no reason. Checked property surveillance cameras and confirmed no one was on property at all. Highly concerned as third-row seating is so close to back window a child could be seriously injured. Glass was found behind 2 ND row. Manufacturer not helpful as they want me to drive with broken glass to dealership on highway to determine if they might cover it.
