    I am considering upgrading my Prius. I have a 2008 with 307,000 miles, I have issues with my engine not yet fully diagnosed and rear brake problems not yet fully diagnosed. I am not sure if I want to put the time and effort into this, so I'm starting to think of getting a new prius. I'd love to jump into a Gen 4 prius but it might be cost prohibitive. I have heard conflicting views on the Gen 3 Prius model. I would like to ask current Gen 3 owners to let me know what they think and offer any advice or warnings. Thank you very much for reading my long drawn out post; I look forward to hearing lots of feedback. Thank you very much.

    2010 Gen 3 -105,000 miles no issues, love this car. Get one with solar roof so you can cool interior on hot summertime days! Make sure oil changes have been done, trans fluid done, and if you buy a car with over 100k have the EGR cleaned.

    No no no, very succinct.

    If you look 3rd gen the prospects over carefully, get one with not too high of miles, you'll be good. Our 2010 looks and rolls just the same as the day we bought it. Only 50K miles though, so knock-on-wood. No oil consumption.

    Did the EGR circuit clean-out, cleaned the intake manifold and installed an oil catch can on the PCV circuit. Apart from the Oil Catch Can, more-or-less zero expense for that. Frustrating, but not that hard.

    Changed the transaxle fluid 3 times, which was at least one time too many. Wax spring and fall, oil change the same interval, all DIY.

    The suspension components are very rust vulnerable, found boiled linseed oil application helps with that.

    2010 118,000 miles. No issues at all. Not even brake pads yet! Like Mendel, I did the EGR circuit clean-out, cleaned the intake manifold and installed an oil catch can on the PCV circuit. Due to time and mileage, I did the spark plugs, and coolant changes. I did the trans fluid once and should do it again soon. Brake fluid is due next.

    Sound great so far, could someone go in depth as to what an EGR circuit is and what is its purpose, and same with the PCV circuit and the reason for the oil catch can. I will try to do some of my own research on these items as well. Please keep all the information coming you can. Thanks

    Our 2010 just clicked over 197 k miles and is running strong:).

    It consumes a quart of oil every 5-6 k miles, which ain’t so bad at the mileage we are at;).

    The egr circuit recycled gases from the exhaust back into the combustion process. Through this, there is particulate that clogs the bits along the way. Occasionally this needs to be cleaned to ensure gases are flowing freely back through the intake manifold.

    An oil catch can ensures any oily exhaust vapors are condensed out prior to re-entry into the intake manifold where liquids do not compress well:cool:.

    There’s plenty to read in the Gen3 maintenance section, but that’s the Cliffs notes version (y).

    Now I am stuck between looking cool or being smart, There is a red 2010, with 86,206, that I'm looking at that is about 1500 less that a white 2011 with 52,591. Should be a no brainer and white is better than the tan, driftwood pearl as Toyota calls it color. Any input is greatly appreciated.

    The Exhaust Gas Recirculation (EGR) circuit cools and returns exhaust gas to the combustion chamber, and is instrumental in keeping combustion chamber temperatures down. It slowly carbon-clogs over time, which is bad.

    The Positive Crankcase Ventilation (PCV) circuit vents the crankcase, allowing air (and oil/gas/water mist) back into the intake manifold, just below the throttle body. Over time the mist condenses/collects in the intake manifold and/or gets sucked into the combustion chamber. The Manifold Absolute Pressure (MAP) sensor is down near the bottom of the intake manifold, tends to be swimming in gunk after a while.

    An Oil Catch Can (OCC) is spliced into the line between PCV and intake manifold, runs the pass-through gasses through some sort of labyrinth, with the object of condensiing and retaining as much of the airborne droplets as possible. It requires periodic dumping.

    Tools: Beside the usual assortment of ratchets, sockets, extensions, pliers (straight and bent tip), in particular for the EGR:

    Torx socket set, E8 for sure (for the EGR studs), and E6 if you want to remove the throttle body studs from the intake manifold

    1/4" drive inch/pound torque wrench (in addition to more common 3/8" and 1/2" torque wrenches)

    Ratchetting 12 mm box wrench (for rear bolts on EGR cooler, not mandatory, but helpful)

    As a rule I would say to buy the newest lowest mileage car you can afford, all else being equal meaning condition of the car.

    Thank you so much for the information. I will be looking at the 2011 tomorrow morning. All the technical information is great. I welcome any more.

    Go for it man. I have a 2010 with 135k miles on it. I cant tell any difference at all when it only had 60k miles. Maybe very little bit, but un-noticeable. Its like since the hybrid system turns off the engine when parked or stopped, or when its running on battery only, I feel like thats why the engine doesnt really perform like its high mileage because its taken care of by the hybrid system. This is just my guess, dont quote me on this lol.

    But overall, high or low mileage is only a very slight difference in performance. Cant even notice it really..

    Caveat my post by saying, this is not the most 'legal' upgrade for a Prius, but it was my first time owning one and I was shocked how much glass there is on the car. I have a 2010 w/ the solar roof and love how the front windshield tint @ 50% VLT seems to blend with the glass roof. Side glass is at 20% VLT, and the lower/back glass is at 5% (also shocked how many truck lights go straight through that lower/back glass, so was happy with the much darker rear glass).

    All of these comments are very helpful. I will be picking up my Blizzard Pearl, (white) 2011 Prius Saturday. I do not have a back up camera like in my 08. I've grown to like it. I would like to know if anyone has done any aftermarket installation of a back up camera or is there any other way to include it on my 2011. Also there is no stock fog lights, when I look at a prius with stock fogs they look like LEDs. When I look on Amazon to buy aftermarkets they say it uses a H11 bulb. I'm thinking of finding a bumper used and harvesting the lights out of that if it's more cost effective than the after market kits. Thanks again.

    I have the stock fog lights on 2010 (Canadian Touring); they're not LED. They're very ineffective too; pretty much ornamental only. I guess there are aftermarket replacements that are better?

    I want able to tell what they were, just wasnt able to see one bulb it the housing looked like a few little ones. The aftermarkets I was looking at use a H11 bulb. From the struggles I had doing aftermarket ones with my 08 and the fitment nightmare I had I was thinking OEM ones would be better. Do you have pictures? Thank you.

    Here is a picture of the type of lights that are on my coworkers car the top is the turn signal and I'm not sure if the bottom is daytime running lights or not. Than I saw some more OEMs on Ebay that might actually be fog lights. I've included some pictures. 20190223_134205.jpg 20190223_134559.jpg

    There's a series of alpha/numeric codes embossed on the glass on ours (OEM Toyota, 2010). Try as I might I could not get a legible pictures, due to lighting, mis-focus. Just reading, I'm seeing, on driver's side:

    Vae0 0D2
    CCC A044633
    SAE F03 02B E2 04709

    Did you get a chance to look at my pics it looks like there is either LEDs or H11 lights both can be OEM, I will do some research
