I had a car with push button start and a CVT. After putting the first 50 miles on the car, the brake light switch died. Nissan, in their ultimate wisdom, used the brake light switch to tell the computer if you are pressing the brake when starting the car. Well, no brake light switch, no starting the engine. Had to get it towed back to the dealership to get fixed.
I now have a real key and a manual transmission.
Jokes on you, some manual cars also require the brake to be pressed to start them.
You know I think your mistake here was buying a Nissan, not a car with push button start
Nissan had probably the most reliable motors through the 80s, 90s and early aughts, then the Renault thing happened . . . so yeah you’re right.
Modern Nissan is pretty hit-and-miss. Their CVT transmissions have a bad reputation too. I have a new Acura with push button start and a manual transmission and all the electronics work correctly with no issues.
I used to have a 92 Honda accord. The car was built on par with Toyota as far as reliability. With that said though, there was one time it wouldn’t start. Push started it, it worked, but when starting- the problem persisted. Went to a shop to diagnose it. Turns out manual cars normally use a clutch switch to tell if you have the clutch pressed to start the car. There is a little rubber standoff on it to dampen the clutch pedal coming back up and hitting it, making it last longer. The little rubber bit fell out and got lodged making the switch not disengage. It was a 10 cent part that cost me an hour of diagnostic time (the minimum). So yes, manual cars still have an equivalent problem to what you had.
