NHTSA Complaint #11481682 — 2015 INFINITI QX60

Random loss of acceleration. Car wont move faster that 2mi/hr. When It occurs, I depress the gas pedal, the engine is silent Put car into neutral or Park and depress the gas pedal and the engine rev's as normal. This has happened several times and a few times while driving on busy highway and almost being hit from behind because vehicle eventually stops and won’t start back up. Brakes would also go to the floor which causes seat belt to snatch you back. My vehicle is unsafe and Infiniti consumer affairs won’t do anything about it. They only fixed the brake issue after a year and 1/2 of complaining about it a technician was pulling it in for ac repair and couldn’t stop. So they replaced all brakes and master cylinder and it still happens but less after brake job. Car will just stop accelerating on highway and so I pulled a carfax and discovered at 4900 miles cars computer had to be reprogrammed and transmission had to be serviced . It was sent to auction from the manufacturer not the dealership why? Car is dangerous for my family and I and will eventually kill all of us that are in it when one of these issues happen at the wrong place and time. Please please help us. Vehicle only has around 62000 miles and I purchased vehicle when it only had around 24000 miles in 2019
