I have less than 500 miles on my 2022 Sienna XLE Woodland. I am loving the vehicle but I've had 3 concerns, one of them big (having to go to service):

1) the most concerning: yesterday when trying to run the A/C, no cold air came out. I will have to take it in for service. Yes, the Eco mode was off (it can override some A/C controls to save gas). It was in normal-hybrid (not Eco or sport) although when parked it always starts as EV (but then again, I should still be able to force the A/C on while parked). Anyway: I tried all modes, temperature settings and combinations. Air kept on blowing out warm as if I had a refrig leak. It was just slightly cooler in the back vents (all 4 zones in Lo) but not what you would call cold. The temp outside was 75F (and later 65F at night). I checked all A/C related fuses and they were all ok. A note here: the vehicle manual does not have a list of fuses (!). Luckily I have a repair CD which has the description but I'm disappointed there is more on bluetooth and infotainment in the manual than on the actual fuses, which is basic for car troubleshooting. has anyone else run into this A/C issue ??

2) To add to this: the vehicle came straight out of the sales lot with the right dash vent not shutting closed. Luckily the trim panel to the far right was easy to find and remove and I pinpointed the issue: the ball-joint arm that connects the wheel to the vent flapper was loose/untethered (really? on a new, $50k vehicle? with 4 miles out of the lot?).

3) and this might just be my inexperience with hybrids but when checking the 12V battery in the back, at one point the battery was off-gassing badly (like I could hear it with a clicking sound and could actually see a little flume of smoke or vapors in the sunlight--didn't seem normal). There is also a clear liquid around the battery which seems like some condensation, or a sealant or something (I tested pH and at least it was neutral--not acid). Seemed weird too. Like slightly oily, as if it were silicone or something. The manual does specify it can off-vent hydrogen gas but this seemed a little more noisy than I expected. And I'm still not sure if the clear liquid on the rim of the battery lid is normal * Any clues on if this is normal? *

Some of this is not living up to the japanese quality standards I had come to expect from my previous 2011 Sienna which I sold earlier this year with almost zero issues in its 125K miles.

1: when people tell you take it out of eco we are not talking about the switch by the shifter. If you go to menu on your radio, info or Settings. Eco. Climate control the eco mode is on there.

2: things happen on delivery my Nabor has a g65 amg that has issues. Brand new $250k suv

3: I would get check out

Correct, just note that IF the overall van setting by the shifter is set to Eco, THEN the van will reset the Climate Eco setting back to ON and override previous Climate Eco settings every time you restart the vehicle.

Thanks for clarifying. I think I didn’t articulate that well enough but yes: I made sure the Eco driving mode and the AC eco mode were off.

Anyway: fast forward to today. Car is at the Toyota service and I was notified there is a leak in the rear coil, above the 12V battery. In a 500mi vehicle. (!).

Clearly I got the lemon.

The leak in the rear radiator explains why the A/C was not working, as well as the clicking/hissing noise and fumes in the battery compartment, and the greasy residue building around the battery (all prt of the refrigerant leak). Will have to remain in service for about a week.

Very disappointed with Toyota on this one. But glad the issue was identified. Of course, all us under warranty so that’s another positive.

Cheers!

Video of the noise of the rear A/C coil leak (I was focusing on the battery at the time because I thought it was the battery offgassing, but the coil is located right above it)

Funny, I actually traded in my 2020 GLE 450 for a Sienna XSE and let me just tell you the build quality on the GLE was horrible. Missing paint spot on the inner door wheel well, mis-matched tire from factory, AC temp sensor blew out a month after delivery, engine was noisy (not in a good way esp for what you would expect from an inline 6), electronic grounding issue left me stranded and the car had to be towed to dealer, interior rattling was bad (chattering noise), body panel near trunk is really loose, I could go on. You guys can bitch all you want about this Sienna but when you spend $70+K on a Mercedes, you think you would expect better quality. That is not the case. The Sienna isn't a luxury car and that's the expectation I had going into it. But what I am getting is fuel efficency / significantly lower operating costs, more practicality for the family, and I'm hedging my bets that the toyota will hold up longer and will be less painful on the wallet compared to the MB. Plus that mild-hybrid system on the MB concerns me long term. Not trying to make this a blanket statement against MB. I still love their S and E classes, but I suspect the quality on those models are better since they are also manufactured in Germany. The S is also their halo car so they can't F that up. Cars are pretty complicated these days (cliche) and I think what I like about Toyota is they aren't the most innovative but stick to tech that is tried and proven. Fine with me for what I'm looking for.

Sorry to hear about your issues, hopefully once the dealer repairs the faulty parts, the van will be good to go.

I also have a Woodland and have had for a little over a week. No major issues yet but did notice that the window washing fluid warning came on just a few days after driving it. I added half almost 1/3 gallon to get it to full. I also checked other fluids in case they did not top it off properly at the factory. The coolant was halfway between full and low. It's odd that a brand new vehicle would not be topped off. It only had 4 miles when I bought it. Now has 200 miles.

Well, the G65 AMG is a Merdecedes after all, so the expectations shouldn't be too high to begin with.

Besides, those people, who drop $0.25M on a rare car clearly prioritize the unique ownership experience over the "mundane" things like the TCO or the initial build quality :)

The dealer is supposed to do things like the windshield washer. Mine came almost empty although there was no light. It took a full gallon to fill.
Coolant expands when it is hot. A level between low and full is normal. As long as it is above the low level when cold, you should be good.
