Thanks. so simple and so important. I have a gen 3 Prius and went to Toyota and bought a filter for the battery fan vent. It is NOT stock with the cars. There is a vent grill but NO filter. When I ordered it (they didn’t have any ). But I made them look it up and “oh yes, there is one and it’s $14.95 (if I remember correctly). And after 10 second installation job, I am now protecting my 2011 Prius fan system. So simple, so cheap. And the dealers don’t even know about them. THANKS.

If I lived in hot and sometimes dusty Las Vegus or Phoenix I would set my iPhone calinder to remind me to vacuum both Sienna battery filters at three month intervals and replace them yearly.. particulary if I hauled a dog/s around in the car, . I'd go to the Parts Department at a Toyota Dealer and buy 20 of those critical air filters. I would also buy four or five extra cabin filters to be vacuumed and swapped out yearly as the hybrid battery cooling is dependent on the cars air conditioning efficiency. Might as well get some extra engine air filters and swap it out at every other oil change. Why? Probably get 250 to 300,000 miles out that very nice Toyota. Alternative: Take it to the Dealer

Realized over the years that the most relisble vehicles and most affordable are japanese makes. I may decide to buy new . The 2021 toyota sienna hybrid.

[@DSPNWtoCali]

You are like Scotty Kilmer but your own version of everything Toyota. I am big Toyota fan for reliability and DIY stuff. You save me many money and headache when most things can be wrench by myself. Appreciate this. We are looking at a newer Toyota Sienna but after seeing the monthly payments even with a good down payment, we have to skip for now until maybe next year. We can buy it but not with the crazy monthly payments even with 8k down. Hmm. The leasing seem like a buy for us and take over the car after the lease is over with the lease buyout. Tempting because we are sitting on a 2009 Sienna with the fuel cost, crazy in this van. 17/25 for fuel is enough to take the dive in leasing the van and go with the buyout once the lease is over. What you guys think? Paying 700-800 monthly or lease with 400-500. We can afford both but the monthly of $700-$800 will burden us and have us live frugally. Lol.

[@TheCarCareNut]

Hi! I am not an expert on money advise but this is the advise I hear. If your ultimate plan is to keep the car long, buying it is wise. If you plan to turn in the lease and get a new car every 3 years so you won’t have to deal with any repairs ever and budget everything around a 400-500 monthly payment then lease. You can lease then buy the lease to lower your payments but in the end when all is said and done you actually paid more for the car and you’ll have payments for up to 9 years ( 3 years lease + up to 6 year financed)

[@DSPNWtoCali]

@@TheCarCareNut wow, I been looking and looking with alot of research. No one mentioned another 6 years to finance the vehicle if lease buyout. Hmm.

Hi I just got a new 2021 LE AWD Sienna about two weeks ago, I had a little accident when I put 5 jugs of water( from a well)on the back of the car(with third row seats down) then I hit the brake hard on the way home, and one of the jugs of water(5 gallon jug) came tumbling down, hit the wall of the car, the cap broke and water spilled on the back seat, I quickly made a stop to an apartment complex, lo and behold, half of the water already spilled( good thing I had a tarp to cover the floor) but water made its way to the carpet. The carpet is soaking wet from the back to the middle seat. I took it right away to toyota dealership, I parked it on a hill in the back of the dealership(I work there as a lube tech). Technician told me as long as there's no warning lights on the dash, then it should be fine and recommended that I should get the water extracted and dried up. An hour later, the detail guys showed up and I asked them to extract the water from my carpet in my sienna. So we walked over to the sienna and saw water dripping from the front of the car because it was parked nose down on a hill. Front driver seat carpet was wet.. I hope water didn't get to the hybrid battery in the front seats. Anyway the detail guys sucked the water out, and let the heater on in the Sienna..and it's now dry..I drove it home and no warning lights. My question is, should I still get the hybrid battery checked?

Honestly if you work at a dealership I would double check the battery. Remove the front seats and the center console and lift the carpet and be on the safe side

​@TheCarCareNut are the Sienna battery fans independent on both sides?

Visually, on the outside, it looked okay. He popped it open and it was pretty dusty inside, the vent inside looked more brown.
