2018 Nissan Armada Engine problems

My 2018 Nissan Armada has had SO MANY issues (probably 15-20) with not starting when cranked. Something is draining its battery. We have had to change the battery so many times (usually 2-3 times every year or two.) This happens without any notice! We have been stranded in other cities, stores, &/or at work. We have tried having it checked out by different repair shops, replacing batteries in key fob, replacing battery MANY TIMES, and checking the brake pedal switch. We are at our Witt's end with Nissans!

UNKNOWN - engine developed knock that could potentially lead to catastrophic engine failure during normal driving conditions, causing loss of control or inability to stop. NTB19-057a is a technical service bulletin issued by manufacturer - cylinder 7 scuffing with a short block or complete engine replacement as the fix. Manufacturer will not replace engine outside of vehicle warranty period, even with documented maintenance proving engine failure is not due to lack of being maintained.

No start, no codes. Have replaced brake switch several times and it fixes it for a bit and then happens again. I have read several forums and it seems to be a commen issue but no recalls for fault. 2018 nissan armada platinum. Shouldn't have to keep replacing switch.

Engine failure at 68,000 miles cylinder 7 scouring like previous years had this issue but my vehicle is affected as well.

It will stall out when we try to start the vehicle. The battery is still pretty new and there are no check engine lights on. It will stall 2 or 3 times but then start about 5 to 10 minutes later.

Randomly fails to start. New batteries installed and still fails to start at random times

This is a 2018 vehicle,but got a dead battery in early 2021. Got a battery change at that time, However having battery start issue again recently. Can start vehicle with a jump starter, however dealer said battery is still good.

Component or system unknown other than personal research. Suspect break sensor or possibly called stop lamp. Again, not positive. My Armada randomly will not start, leaving me stranded many times (with children). When I push the start button, sometimes the car shakes while making a horrible sound and trying to start but never starts. It has to be jumped off before it will start. Sometimes, it just clicks and does nothing. We took to our local Midas, who found no codes triggered, battery, alternator, starter etc all...

My Nissan Armada is 4 years old with 42,000 miles and has needed two brake switches replaced on it to date. This is RIDICULOUS! This car is completely unsafe. It has failed to start more times than I can count, and it most recently broke down on my on New Years Day. I had to have it towed. I have reported this issue to Nissan and they have done nothing to help make this right! I am now starting a FaceBook group (of other Nissan Armada owners that are experiencing the same issue) to file complaints against Nissan for this. This is a serious safety issue and needs to be resolved.

Vehicle tends to lose power when gas pedal is engaged. When foot is off the gas and brakes are applied while idled at traffic light vehicle tries to accelerate. I constantly have to be mindful to keep brakes firmly pressed.
