Sliding door on driver's side jammed.....at an angle. You could see daylight at the bottom. Door could NOT be budged! Totally locked in place. Much looking on-line did not show me what to do. Several sights showed how to unlock a door by taking the small panel off at the inside handle, but this was not the problem. I finally solved the issue by taking off the entire door panel, at least partially, due to the door being stuck. I then could see the latching mechanism located midway, on top. I could get a long, large screw driver on it and gave it a good push.....unlocking the rear locking mechanism. Once the tension was released, I could open the door and take the entire door panel off. The one bolt on the very bottom could now be reached. Solution? total lubrication/cleaning of the entire mechanism, including guide rails, pivot bearings, latches, etc. Works fine. Learning from this situation, I naturally did the same lube/cleaning of the passenger door too. I'm skeptical of using the electric powered mechanism after reading of do many user problems, so we just manually open the doors. Hope this helps someone!

Toyota Sienna in New Jersey, United States Jan 2009 - Sep 2013
Jan 2011 33000 mi US $90	Tire pressure warning light has NEVER worked properly. Almost impossible to get the dealer to take it seriously. They reset it and send you on your way and 10 minutes later the light comes on again. There is even a TSB on it. Car makes a grinding noise after a cold start. Getting worse, but we were told they couldn't duplicate. Weatherstrip from driver's rear quarter window coming loose. Not covered under warranty. Over $100 to replace. Going to try to fix it myself with 3m adhesive. Both passenger door weather strips falling down. Dealer reattached. 2nd row seatbelt slow to retract. Twisted and appears to be fraying at attachment point. Was told "could not duplicate" which is just ridiculous.
May 2012 48700 mi US $70	Check engine light on. Failed O2 Sensor.
Sep 2012 52000 mi US $2500	Trainsmission failed after vehicle was driven through puddle. Replaced transmission.  Replaced failed o2 sensor at this time.

Toyota Sienna in South Carolina, United States Aug 2007 - Jan 2011
Jul 2010 32000 mi	The rear blower of the air system at times comes on by itself even when I have not turned the rear air on. The rear blower of the air system at times comes on by itself even when I have not turned the rear air on After I had two tires replaced, the TPMS light began to glow.

Toyota Sienna in Utah, United States Jan 2021 - Sep 2024
Jan 2021 195000 mi US $500	Water pump was squeaking. Replaced water pump with OEM Toyota pump, as well as OEM Toyota thermostat. Old water pump gasket came apart and took hours to remove old material from engine block. Previous owner had a mechanic install a non OEM Toyota water pump which uses a felt gasket. Bad choice. Replaced bearings on serpentine belt pulleys and tensioner. (A total pain but much cheaper than new idlers and tensioner from Toyota.) Also replaced serpentine belt.  Also added Lucas PSF stop leak to power steering fluid since it was leaking down all the way to the transfer case and transmission and was mistaken by a mechanic as a leak at the transmission or transfer case.
Mar 2021 196000 mi US $400	Front brake calipers were rusty and corroded. Front rotors were in need of replacement as well. Used next generation Sienna brake calipers instead and rebuilt them with a rebuild kit. Bought Toyota OEM brake rotors and pads (for next gen Sienna/Highlander) to match calipers. Much improved stopping performance. This car needed stronger calipers and bigger rotors from the beginning.
Apr 2021 196000 mi US $120	Door check device had failed. This device holds the door open when on a slight decline. The door was not being held open and was dangerous since it can close on you while getting out. New door catch was very expensive for what it is. Honda Odyssey door catch is much cheaper for example. Removed door panel, removed old door catch, and installed new one. Also replaced window switches since the old one had lost all writing and looked very bad.
May 2021 198000 mi US $35	Vaccum lines running to airbox were split and worn. Replaced vacuum hoses as well as installed new OEM Toyota engine air filter and Denso cabin air filter. I recommend only Toyota OEM engine oil filter as other filters don't fit well and aren't much cheaper.
Jan 2022 203000 mi US $300	Rear calipers, rotors, pads, and parking brake shoes replaced. Calipers were not braking correctly and created uneven pressure on rotors. Attempted to replaced brake hoses near calipers as well, but they were too rusted even after using penetrating oil for a couple of days. Will need to replace them probably, when it's warmer. Braking performance is MUCH better. Parking brake adjusted after installation of rotors, calipers, pads, and shoes. Also took this opportunity to install Timbren rear suspension system to decrease rear sag when loaded. What a pain.
