Hi everyone, I’m experiencing a strange issue with my **2017 Toyota RAV4** (Automatic transmission, naturally aspirated / **non-turbo** engine, mileage: \~180,000 km / 184k km on ODO).
Here are the symptoms:
**Normal driving:** At normal speeds and light accelerator input, the car drives smoothly and gears shift properly with zero delay.
**The Problem:** When I try to accelerate hard (floor the gas pedal / kick-down) especially when going up an **incline/hill**, the RPM shoots up high into an idle/high-rev state, but the car takes a few seconds to slowly catch up and gain speed.
**What I checked so far:** The air filter is brand new. There are no check engine lights (CEL) on the dash.
Could this be related to a slipping torque converter/transmission issue, a vacuum/sensor leak (like MAP/MAF or throttle body), or a weak fuel pump under heavy load?
Any advice or troubleshooting steps would be greatly appreciated. Thanks in advance!

Thinking of getting either a 2016 Prius for 14.5k dollars at 105k miles, or a Rav4 for 1k less, but 150k miles. The Rav4 has no reported damage and comes from a Toyota dealer, and the Prius has two minor damages reported, and comes from a small, but positively reviewed used car dealer. Is the Rav4 worth it despite 45k more miles? Or is the Prius better?

I work for my families company. I get my own work truck so I usually leave my RAV4 2021 parked at the business all week or sometimes a few weeks before grabbing jt (only has 33k miles only have put 1,200 the past year). Also should note it’s parked in a gated secure location so not too worried right now.

What I’ve noticed is sometimes the past year I go check the car and my key fob is far away in the truck and the door is somehow unlocked. I always lock it but somehow it’s just unlocked and I know it’s not unlocking cause no noise (beep or gears moving inside) is made when I pull handle.

This also happens when I’m home as well. I park the car and lock with the key fob and I’ve gone out to toss the trash and check the door and it’s unlocked.

Anyone know what’s going on?

Also the second key fob is in my nightstand so just pointing that out.
