Rear AC turns off randomly.

Toyota Sienna 2011 Van 200000 miles
While driving the rear A/C will turn off. The green power light will go out and the fan will stop. The front A/C is unaffected and blows cold. After this happens I can turn it right back on without any issues.

Gas Spew from tank

Toyota Sienna 2019  45000 miles
I drove several hours on a 100° day, air conditioner blasting. Gas tank was 3/4 full. Went to open cap to top it off, and roughly a gallon of gas spewed out of it all over me and the ground. Started driving again, 2 hours later i stopped and waited in shade for 20 minutes, turned the gas cap again, and it hissed at me like a cat, no gas came out. No engine light, no messages.

Cruise Control not turning on/working

Toyota Sienna 2012 Toyota Sienna XLE 120000 miles
It's as if I don't have cruise control at all. It doesn't turn on, flip on any light on the dash, nothing.
My question before I go buy a new #32 fuse is, if the cruise control fuse is also responsible for power doors/power steering/wipers etc but all of those things work just fine, does that mean it's not the fuse that's the issue? My brake lights work fine too, so I don't think it's the brake sensor...I'm kinda at a loss, trying to figure out if this is something I can do myself before I spend money I don't have at a mechanic. Thanks so much for any advice.

Best answer (according to Vulcan Rider)
Vulcan Rider from United States 4 months ago
I had to take it into a repair shop - it was out of freon - they rechecked for a leak - filled it - ran for 2 hrs - called to say it was done - THEN called back to say it was still leaking and the rear lines to the back of the cab under the frame had rusted out -!! :( so $600.00 of OEM steel lines + labor + 2nd recharge of freon and all is well. Just upset they missed the leak at the then "1st die color test " - :( But they have done a good job on other items that I could not fix at home -So I may return as needed. As long as it works for the next 10 years I will be happy ! so IF ANY ON HAS AC LEAKS - make sure you or the shop checks under the frame back to the rear AC vents. !

Clunk on front drivers side suspension

Toyota Sienna 2015 SE 132000 miles
We had the lower control arms replaced and now there is a significant "clunk" or Pop when braking or taking turns. Anyone experience this before??

May be the front strut! the bushing at the top plate where it mounts ware out - and can "clunk" as the strut is doing its thing - pushing UP on the mounting plate. If around the 100,000-mile range or even a bit lower they need replacement for a better ride. Did mine at the 100,000 miles ! no noise but much better in turns / ride. Rear should be changed at the same time. ! :) have a shop check this out ! :)
Yota Healer from United States 5 months ago
This is a great idea, as I didn't see any play in any linkages or joints (brief physical inspection while on stands), but i didnt check the shock mounts up top and I know Im due for them! Many thanks🤙🏽
Vulcan Rider from United States 5 months ago
@Yota HealerNot cheap to replace them but needed sometimes. :) rear shocks are a 5 min job per side... ! when you lowered the Assy - if they were about wore out - a little extra stretch may have done them in ? :(

Overheating

Toyota Sienna 2012 Xle  112000 miles
Did the alternator and had to takeoff one of the radiator hoes to get to the alternator. Cooler came out, topped it back off with coolant and try to bleed the system, but I noticed the bleed screw is a little bit loose. Not sure if that’s my problem.

Get a fuse panel diagram and see where the fuse panel is at (most likely under the dash by the steering wheel) and the diagram will show which fuse is for the UBS port and see if it is "blowen - bad " if so it a ez fix. ( You can get the diagram on here - very detailed ! :)) good luck ! :)

Driver side mirror has a visually jarring wiggle when changing speeds

Toyota Sienna 2016  50000 miles
My side mirror has a bit of play in it - when I change speed quickly it shifts forwards or backwards just a bit, enough to shift the field of view but not enough to be dangerous.
My shop said the play is in the mechanism the opens/closes the mirror but the only fix is to replace the entire driver side mirror.
Any thoughts?
Thanks!
