I am writing to report serious safety concerns regarding my 2017 Infiniti QX80. The vehicle has exhibited two primary issues: 1. Unintended Braking: The vehicle has a tendency to suddenly and unexpectedly brake, particularly when driving over specific road surfaces, such as brick-paved intersections. This behavior is extremely dangerous as it can lead to accidents, especially in high-traffic areas. Such abrupt braking can cause the vehicle to lurch forward, potentially leading to rear-end collisions. 2. Frequent Battery Drain and Failure: The vehicle's battery drains rapidly, requiring frequent replacement. Despite multiple visits to the dealership and attempts at repair, the issue persists. This problem significantly compromises the vehicle's reliability and can leave the driver stranded, particularly in emergency situations. I have taken the vehicle to an authorized Infiniti dealership multiple times to address these issues. While the dealership has attempted repairs, the problems have persisted. The frequency and severity of these issues pose a significant safety risk to myself and other drivers. I urge the NHTSA to investigate these issues and take appropriate action to ensure the safety of all 2017 Infiniti QX80 owners.
