You definitely don't need to dismount the transmission to change the fluid. There is a drain plug right underneath it and a fill plug on the side. It takes about 15 mins to do a complete drain and fill

It's time for a trip to the dealer

Probably, but be careful as there are 2 different ways to test a battery. The quick way takes a couple mins and the long way takes a couple hours. Mine tested fine the quick way but all problems were solved upon replacing it

A new 12v battery fixed all my issues

have a 2013 FFH. Just bought it a month ago. Drove it for a couple thousand km and all seemed normal, fuel economy was decent etc.. then one day recently z seemingly out of nowhere, fuel economy got quite a lot worse as a result of EV mode disengaging with nearly any gas pedal input. Some research suggested this could be the result of a bad 12V battery. Fast forward to last night. After driving throughout the day, I parked the car and attempted to start it about 2 hours later. It wouldn't start, and I got a message to "Stop Safely". When trying to start the car again, it was as if the gas engine would half engage, but pedal and gear input did nothing and car wouldn't move and a short time later the gas engine would just shudder to a stall. I have a phone charger that has a voltage readout on it. It was getting low, reading as low as under 8V. I attempted to boost the car, and even with the voltage reading 12.6, the car wouldn't react, eventually getting a Wrench icon. Throughout all this, the hybrid Battery icon showed empty/no charge Fast forward to this morning, the car started fine, all warning messages gone and after a few mins the hybrid system appeared to be charged as expected. I drove it to a local shop to have the 12V battery tested. It drove fine, other than still having the issue where EV mode won't stay with any real amount of gas pedal input. The battery tested fine, and I'm now not sure where to go from here. Any help or insight, other than just suggesting I take it to the dealer, would be greatly appreciated

The CEL is for an evap leak at the fuel fill neck

My 2013 FFH, just yesterday out of nowhere, doesn't seem to be functioning properly. Mainly, the EV mode will only come on when coasting/braking for the most part. Basically any gas pedal input activates the ICE (internal combustion engine). Car has 170000km but was working fine in this regard up until yesterday. This has caused a fairly significant reduction in fuel economy. I read some stuff about a hybrid battery age counter needing reset but seems to only be for the 10-12 models. Also worth noting is the hybrid battery drained close to zero twice yesterday and that's also never happened. And when I turn the key off but leave accessory on, it now allows me to play music indefinitely whereas before it would typically only let me play it for a few mins and would then shut-off with a message on the touchscreen stating something about preserving the battery. And the "status" screen seems to be showing "charging" a lot more, even when in electric mode, when it's coasting it says charging as oppose to Electric drive. This may be normal and I just hadn't noticed before. Also at times, the idle when the gas engine kicks in can be quite rough, almost erratic like the RPM is going up and down, well, erratically. It also kind of shakes the car a bit at times too. Just generally not very smooth. Otherwise it seems to drive ok. Yesterday, it was really revving high then low very quickly, my wife was wondering what the heck was going on. I noticed there is an arrow either above or below the battery on the left dash screen. It appears to signify whether the battery is charging or discharging. In this case, the arrow seemed to bounce from top to bottom of the battery in sync with the revving.
