      Hello,
      I also have a 2010. She has 235,000 on her. I am hoping for another 100K. I can't help but wonder what a newer Prius might be like in the way of features, handling, reliability and reduction in road noise. If you were to consider a new Prius, what would you choose when viewed through the lens of quality of build, lack of factory issues, etc.? I was thinking somewhere around the 2019?

        The base 2019 Prius still has a spare, that’s the only one I’d consider. 4th Gen had coolant leaks in the exhaust heat exchanger, which if neglected to the point of coolant starvation can cause engine failure. That “may” have been fixed by 2019, not sure.

      Thank YOU for comments ! The whoop-whistle was caused by air in the high pressure line. It's GONE, but I am still not happy with my brakes. The fluid level rises 1/2 inch over night and the brake pedal seems soft. I can press it all the way down to where it "hits metal". Car drives fine and Toyota dealer says it is OK. Have U heard all this before [and solved it?]?

        "The fluid level rises 1/2 inch over night"

        ^ That's normal. If you open the front passenger door, reach across and pop the hood, and then go around to driver's side and open that door, the brake pump will (typically) activate, and if you're quick you can see the level dropping down. About 1/2".

        The spongy brake could be due to air in the system. That said, the gen 3 brakes booster is failure prone.

        Thanks for your comment, Mendel! I figured that out myself during the night as often happens. I'll test drive another Toyota asap and compare the brake pedal stiffness with mine.

      Thanks for all your assistance in wheel-bearing replacement advice. I couldn't "crimp/indent" the axle-nut. mark was directly downward and I couldn't get enough force to create an indentation. I was going to drive it to move it. Is the viable or does it always point downwards now? How to crimp it as well? I used a small hammer and screwdriver to no avail. Thank You.

        I am going to try again. I think I was just too apprehensive about hitting the axle for fear of breaking something.

      I have a 2010 prius w 130,000m,and a booster pump running every 10 sec. I plan to change the brake booster/actuator.
      1. Would you advise me to steer clear of BAM Auto.
      2. Can I use techstream and complete bleeding procedures without a scanner?
      3. If I go forward w the Techstream plan what dongle and cord would you recommend I buy?
      4. At some point I would like to buy a scanner. Do you have a recommendation

      Mr. Mendel I installed a new master cylinder because changing the booster pump and accumulator did not prevent the pump from running every 14 seconds. Now the new master cylinder emits a chirp [sort of a whoop sound] most of the time when I touch the brake pedal. Have you run into this problem before ? I think the Toyota dealer should exchange it for me.

        Yes, I did all the work myself; brakes and head gasket. I can feel the vibration in the red brake line. I will try damping it. THANK you for your help. Our retirement village has been built and maintained mainly by Canadian SnowBirds !

        Replacement booster pump failed so I put the good original back in. In this process, air escaped from the pressure line and the "chirp-whoop-whistle" sound is GONE ! Hallelujah !

        Now the fluid level rises 9/16th inch over night. That indicates there is air in the m/cyl. & Toyota Dealership bleed failure. Do U agree ? What should I do ? Car drives FINE 2700 miles.

      Mendel you have helped me in the past with my Prius. I need your help again.
      I have 2013 Prius Plug-In with 20k miles on it. after thw replacing thermostat it started gi=ving warning :check hybrid system stop vehicle safe pace" It seems like something happened during the repair caused it. i t was working
      1. Mendel Leisk
        Mendel Leisk
        20k miles?? That's the thermostat right next to the water pump (engine coolant pump)? Did you do a coolant change as well? Not sure: check all connections, and that doesn't work turn anything up get the codes read?

      Mendel, I've been on here for years and have benefited tremendously from your sage input and generous sharing. Thank you so much for all of your outstanding contributions over these years. Because of you (and others....but I have learned to certainly trust you) I've become quite a decent DYI'er on my 2013 Lexus CT200h.

      Wondering if it would help to take the ring off from around the coolant cap, so it doesn't seal? I've read where they say it takes the pressure off the coolant system and gives you more time to avoid damage. You think that's worthwhile?
      1. Mendel Leisk
        Mendel Leisk
        Not sure. I’d post in your thread

        removing the O-ring off coolant cap greatly reduces the ability of the system to cool the engine because the increased pressure with the seal raises the boiling point of the fluid which is a very good thing. Some remove the ring or just dont tighten the cap in early stages of head gasket failure to prevent the cylinder from filling with fluid after a drive.

      Hey! I know it's been asked before but there are a million opinions. My 12v battery just died in my 2008 Prius. Do you have any recommendations for a battery or at a minimum can direct me to a specific battery that would work?
      Does Walmarts brand Everstart work and are they reliable?

      Thank you so much!

        I used a $30.00 lawn mower battery in my '05 Prius for at least 3 years. I would have done the same in this 2013 Prius but a friend gave me his used HONDA CRV battery, and when that failed my son shamed me into buying a similar replacement = size 51R or R 51.

      I appreciate reading your posts in expectation of inspection and cleaning of the EGR and intact tract. Just to make sure, you are of the opinion that one can remove the two horizontal studs and not replace them after the job is done? Or just the rear one that is so difficult to get at? Thanks.
      1. Mendel Leisk
        Mendel Leisk
        I would only remove the lower cooler stud permanently, since access is so difficult. You also do need to remove both the nut and stud at the EGR valve, temporarily, ditto for the bolt through top bracket of cooler, and the two nuts at rear, connecting to exhaust manifold. Since those two side studs are removed you don’t need to remove the studs at exhaust manifold.

      Mendel you can probably identify this issue! I have a 2011 Prius and on January 20th of this year, this loud hum noise started http://link.www.ridesharedriver.blog/Prius_hum_noise. That is from a mic on the "Shotgun seat" While I am driving on Interstate 275 in Tampa, FL. The noise is very loud in the car. When I get over to the left or make a left turn the noise goes away. What do you think?



      Thanks,

      Sean

        Does it change pitch with speed? What’s the miles? Original wheel bearings?

        Maybe start a thread, include above info.

        The pitch does change a little. I think it is the catalytic converter. There are 543,000 miles on the car. The wheel bearings have been replaced twice, There is a detailed maintenance log at my website.

      Look, I'll wait a bit. My left shoulder is "fubar" or " comminuted, compacted, 4 part, fracture of the proximal humerus " to be accurate. It will take about 3 months to heal.

        I hope your shoulder is healing well and you're slowly gaining full use with no significant pain. I'm an emergency physician and know one of the best shoulder surgeons in the country if you should need one. Often you do not. Aspen Colorado Steadman Clinic, Dr. Jerod Lee. Just in case.

      Hi Mendel....this is Bill from Seattle. Do you ever drive south down to my area? I am close to Everett. Would be nice to meet for lunch! I love to talk Prius....you seem pretty knowledgeable. Many years ago I went to a racetrack for a sports car race....I think the track was near Coquitlam or Mission....is that right?

        Sorry, no. This is a Toyota accessory, a side moulding held on by adhesive? You’ve tried googling?

      Mr Mendel,

      What voltage should my 12v be in? I was checking for codes with OBD the other day and my app said my 12v had 11.8v while it was on the on position checking for codes (pressed on twice) not running/started. Let me know if that's too low.
      1. Mendel Leisk
        Mendel Leisk
        At least 12 volt. I’d be concerned if I saw anything lower than 12.5

      Would you mind looing at my "What to buy" post in Gen II?
      BC is da best. Spent time in Squamish this winter. Best compliment I got was that I was the most Canadian American the people in the car had met. I blushed, I love that country. Originally from VT. Daughter in on V Island for a while this summer.
