Warnings problems of the 2015 Infiniti QX60

The brakes will go to the floor on its own and won’t stop and almost rear ended vehicles or ran lights due to not being able to stop. The brake issue has been reproduced and noted on service records. I am a 100% disabled veteran that requires a mobility scooter for mobility and appointments. The other issue is the vehicle will loose power anywhere and anytime and has to be towed in by aaa to the Infiniti dealership every time and they say the issue cannot be reproduced and I have gone thru their complaint system and they are in the process of sending technicians to finally look at the vehicle. I am afraid if this car because the last time it happened it almost killed me because it just lost power and brakes on an oklahoma interstate at around 70mph and had to coast to the right side service area to wait for aaa was almost rear ended twice in the process of getting to a safe area. My family and I are in danger anytime we drive this vehicle and have an extended Infiniti elite warranty thru manufacture. The vehicle in question is a 2015 Infiniti Qx60 and was purchased in 10/16/2019 with 24555 miles on it and have had problems with car since day one. Please please help we do not want to die. We have all recorded messages where Infiniti makes excuse after excuse after excuse to do anything about our safety.

The vehicle on at least 4 occasions has stopped accelerating when driving the vehicle (first time I believe was fall 2021, this last time was spring 2022). Most of the times that the issue was noticed, the car was was moving at slower speeds (35 or less). The engine remained running but pressing on the gas pedal didn't make the vehicle increase it's speed. The first time it did this we took it to the dealership to inspect. They could not replicate the issue and they said that no error codes showed up. We left with no repairs or answers. It happened 2 more times after that. Each of those times we were able to stop the vehicle and get it to go again or it would start to respond to pushing on the gas pedal and would accelerate. The 4th time this happened I was in the middle of an intersection turning and it wouldn't accelerate. I was able to slowly roll into a gas station. I tried stopping and turning the vehicle off and on again to see if the problem would go away, however each time the car only slowly inched forward. I parked and then the vehicle started acting weird. The ac shut off and the steering wheel locked. There were three error lights that came on. The first said "fcw malfunction see owner's manual" and second was "iba off" and then the "! inside a triangle" appeared. These appeared only after stopping the vehicle for the last time right before it wouldn't start again. The vehicle was towed to the dealership. The error reading they got was c1601 and they believe the alternator needs to be replaced. This doesn't seem to line up with the issues we have been having nor the error warning lights that appeared. The last time this happened my child was in the car with me. Had we pulled out to turn and the car wouldn't go we could have very easily been hit by oncoming traffic. It is very troubling that the dealership doesn't seem to really know what is wrong with the car.

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.
