Gear linkage? Control unit? I'm not really a car guy, so I'm not sure what that means. Is it something I can check myself, or should I take it to a mechanic?

Probably best to take it to a workshop. My issue turned out to be a defective control unit in the automatic transmission. It caused all sorts of weird problems, like the engine not starting and the transmission acting up. Better get it checked before it gets worse.

Thanks for the info! Sounds like that's probably the problem. I'll take it to a shop and have them check the transmission control unit. Hopefully, it's not too expensive to fix. The mechanic confirmed it was the control unit, and the repair cost me about 1000€. Appreciate the help!

Sounds familiar. I've got a Pathfinder too, and I had similar problems last year. The gearbox was acting up, and sometimes it wouldn't even start. Have you checked the gear linkage? It might be a control unit issue.
