  1. The discs are necessarily rusted. The Mot mechanic has to click on a fault code. The words "Front Brake disc worn, pitted or scored " is the catch all phrase for anything wrong with the disc. All I'm saying is that I had a Gen 2 and now a Gen 3. Both have been run in virtually identical conditions. Both about 12,000 miles a year, garaged in the same area. Both molly coddled by me. The Gen 2 had the same discs & pads after 70+k miles. The Gen 3 has "Front Brake disc worn..." after 21k miles. Can this be a true reflection of the difference in quality?
  2. Thanks for your replies. I agree with everything you've said! Perhaps I'd better explain my curiosity. I have a 2010 Prius, 67000 miles, bought second hand from a Toyota Main Agent about 2 years ago. Full Toyota Main Agent service history. According to the 'customer portal' on the toyota.co.uk website - where I can see my car's service record - the front disc rotors were replaced 21,000 miles ago. I had my car MoT'd last week and an 'Advisory' said "Front Brake disc worn, pitted or scored, but not seriously weakened" I think I'm gentle on cars - I regularly get 62 to 65 mpg and I sold my Gen 2 Prius (2 years ago) with 72,000 miles on it - and with the original rotors and pads. My thought are: 1) Gen 3 rotors could be much, much softer than those fitted to the Gen 2. 2) The Toyota main agent who changed the rotors fitted non Toyota parts. 3) The Toyota main agent did NOT replace the rotors at all. As the previous owner was UK Power Networks, I'm guessing the driver didn't pay the service bill, nor did he care what was done to it. So, No 3) is my favourite option! I guess what I'm asking is: Is it as outrageous as I think it is (or even totally impossible) - to have the rotors wear out in 21,000 miles?
  3. I'm trying to find out what is 'normal' wear for the front disc rotors on the Gen 3 Prius. Have any of you had your front disc rotors replaced due to normal wear - and if so, what was the mileage covered by the car at the time?
  4. If you've had your catalyst stolen and the car is out of warranty, there are alternatives to buying a genuine Toyota part - and waiting months. I've no experience of them, but this business came came up when I was searching for something else: https://www.bmcatalysts.co.uk/
  5. Are you still following this thread? I think I've found the reason for the resonant 'thud' on my 2010 Gen 4 Prius. I mentioned before that the doors seemed to give off the same 'thud' noise when I bump them with the soft part of my hand. I've already stuck on heavy anti resonant pads to the inside of the door skins. They removed the cheap 'ting' noise when they were tapped with a knuckle but not much else. I came across the service manual for the 2014 Prius and it shows a 'cushion' pushed up against the door skin - it being bolted to the side impact bar: My doors do not have this pad. Further, I can't retro fit it, as the side impact bar runs in a different direction and doesn't have any holes for the bolts: I suspect Toyota modified the door and changed the angle of the side impact bar to incorporate the cushion. And (I'm guessing) they added the cushion to stop the door skin resonating and annoying their (more pedantic!) customers. So, I know the solution but I'm unable to do anything about it.
  6. Thanks for your comments on tyres guys. A slight change of direction..... Toyota's might be noisier than other cars, as their money is spent on (probably) the best drive train in any car, and not on the best suspension etc. So, I was wondering, is a Lexus CT200 a much quieter car? Same drive train as the Prius / Auris / Corolla but a more expensive car that is more 'up-market'. Is the cabin more refined?
  7. I always thought the 'door draft' was Toyota's way of keeping the door skins dry - helping to prevent rust forming. But, good point, if the draft can get in the cabin, so can noise. I found this the other day, I wonder if anyone has any experience of it. "50% less noise" is a substantial claim! Goodyear Tyre
  8. I understand what you say but 75dB for 6 hours on a motorway gives me a headache for a few hours - and tinnitus for days afterwards. It's not amusing! Cars might be silent when not moving, but dragging tyres over (say) a ribbed concrete surface at 60mph certainly swamps any noise of passengers breathing. I'm not remotely wishing for silence, just a cabin noise level that doesn't approach the (80dB) lower limit where (if I was at work) my employer would need to supply ear defenders.
  9. "The rear is 33 PSI, so you are only 1 PSI short". Sorry - you are NOT correct. My 65 section tyres are spec'd at 35psi front, 36 psi back. (See photo.) The user manual and the door jam info confirm this. It's the 45 section tyres that should have a32psi. Yes, the rear hatch and the rear tyre-well received the same attention as the rest of the car. Several heavy weight vibration pads, followed by 10mm of closed cell foam (CCF) and Mass Loaded Vinyl (MLV) over the whole lot. In addition, I've installed a MLV / CCF / MLV sandwich mat which covers the (flat floor) whole boot area. The only thing things in the under-floor area are light weight and on no concern. A space blanket, plastic mac', a high Viz jacket etc. TonyHSD: The Porsche video was (as you suggested) fascinating. However, the Porsche is (probably) worth 10+ times what my 2010 Prius is worth.... It would be (equally) fascinating to see a comparable Toyota video! I totally accept the springs, shock absorbers and bushing will have a major effect on the perceived ride quality. However, there is little I can do about these. I wish there was! (Suggestions very welcome!) It never occurred to me that the tyre manufactures would spoil the cabin noise to reduce the 'drive by' noise level! If anyone has a suggestion for the quietest "in cabin" tyres I'd be grateful to hear from you! Many, many thanks for your contributions. I'll always be grateful for any ideas, but I've a feeling I'm going to have to accept the 'bass drum' noise as a cost of Toyota 's reliability and low cost maintenance. Hey-ho!
  10. A point of view that hadn't occurred to me! I have already fitted heavy weight pads to all the door skins when I gave the whole car the sounddeadenershowdown treatment. (See pic) They stop the door panels from sounding like a tin can when tapped, but they don't seem to effect the deep 'thump' noise. I've added more heavy pads and then removed them - all to no effect. I guess I'm just going to have to live with the deep 'thumps' and accept it as part of the car's characteristics!
  11. Hello all Many, many thanks for your numerous comments and feedback. I'm slightly overwhelmed by the number of replies. Thank you. There have been many ideas and I'll try to address them all: I have 15" rims and 65 section tyres. It was a deliberate decision to buy a car with this equipment as I believed it to be the quietest option. I'm still convinced by the idea that the larger the tyre profile, the quieter the ride. However, I had Michelin Cross Climate tyres fitted when I was mainly concerned about "tyre roar". I accept that the EU noise level is a "drive by" level but I assumed the quieter the "drive by" noise, the quieter it would be for the cabin occupants. What else is there to go on? Since then (having insulated my car from tyre roar) I'm more concerned with the 'softness' of the side walls. I have no idea if the Michelin Cross Climate are good in this respect. When the tyres need replacing I'll consider another make / model and I would welcome suggestions! An interesting side note: Thin sidewall tyres were originally made for performance cars that needed massive brakes. Massive discs needed larger wheels to accommodate them. Larger wheels needed smaller side wall tyres to fit the car. But - now - skinny side walls seem to be a style statement. Whenever I see these skinny tyres on a car I think: "Pimp my Ride!" The comment about the VW Polo having a more refined ride was fascinating. It gave me a lot to think about. I had a (recent) ride as a passenger in a (made in Germany) 2016 Ford Focus. The lack of tyre roar and "road thump" was staggering - compared to my Prius. More later.... The under trays / bumpers are not the problem nor are exhaust shields etc. There simply isn't enough mass in them to produce the deep 'thump' that I hear. They would rattle as opposed to 'thump' . However, it was a great idea! Thank you! I have put some more air in my tyres. However, not to the recommended level. Looking at other similar cars (BMW, Vauxhall, Ford, Hyundai and other Toyotas) show the rear tyre pressures are set at 30psi to 32psi. I think that the rear tyre pressures on the Prius (35 psi) are to aid a lower fuel consumption figure. Mine are set to 32psi but I'll increase them to 35psi when "sustained high speed driving" is anticipated. Thanks for your concern. Don't ask me why, but I 'bumped' the middle of the doors on my Prius with the flat of my hand. I heard a deep "thump" and immediately thought "that's it!" . It (seemed to be) the same deep 'thump' I hear when driving. I applied the same 'bump' test to the doors on my friend's Ford Focus. Absolutely nothing. No 'thump' what-so-ever! I wondered if the Prius had super thin (weight saving, fuel saving) doors compared to other cars - Ford Focus, VW Polo etc. I removed the interior trim panels on my Prius but could see no way of giving them any extra support - as the window glass (obviously) slides down into the middle of the door. There is a thin, folded piece of steel that runs across the outer door skin and is attached to the door skin by thin rubber 'splodges'. I'm guessing that it is there to give some sort of rigidly to the door. However, it is so thin and light weight (you could probably bend it in your hands) it seems to do (to me) almost nothing. When I "thumped" the middle of the doors on my Prius I was surprised how much the sheet steel actually moved. I'm guessing , but I wonder, if the 'thump' I hear is the door resonating with the road irregularities and moving the air inside the Prius cabin. If this is what I'm hearing, there is nothing I can do. The doors are thin and they resonate. End of story. Do any of your doors move in the same way - and give such a deep 'thump'?
  12. Yes, I have the 15" wheels. (65 section tyres.) I use Michelin CrossClimate tyres, as they are (supposed to be?) one of the quietest tyres available at 69dB I'm sure the 65 section tyres help soften the 'thump' as there is more tyre wall to flex and absorb the impact. But still, too much 'thump' is entering the cabin and I was seeking way to reduce it. Any ideas will be gratefully received!
  13. Hello all - I've a 2010 Prius T Spirit - with sunroof - and 195/65 tyres. 60k miles and a full Toyota dealer service history. I've been 'blessed' with exceptional hearing. (Or perhaps it should be 'cursed'!) I'm a piano tuner by trade. My Prius is everything I want from a car and fairly quiet, but I wanted it even quieter. I followed all the advice that was given by: https://www.sounddeadenershowdown.com/vehicles/toyota-prius-4-door-hatchback-2010 It was brilliant information and reduced the tyre noise / road roar to sublime levels. (65dB on a fast A road.) I've also reduce the rear tyre pressures to 28psi - which has also helped. However... Although the tyre noise is reduced to almost zero, I've uncovered some sort of resonate 'boom'. Probably because the tyre noise has been reduced so much, I'm (very much) aware of a 'thump' or 'boom' every time I drive over a road bump. Any road bump produces a 'thump' from the back suspension. It's as if someone is thumping the underside of the car with a rubber hammer. It ruins an - otherwise - supremely quiet ride. I took the car to a Toyota dealer who "tested" the suspension. (I suspect they looked the rear suspension and gave everything a good shake - and nothing more.) Am I resigned to this inherent noise from the suspension? Any suggestions anyone? Kind regards - Andrew
  14. Surely it's just coincidence? How would anyone at Toyota GB know who you are? All the information (about you) that's on this forum is: First Name David Gender* Male Toyota Model Prius T Spirit Toyota Year 2014 Location Gloucestershire
  15. David - good idea but.... The steering shaft was replaced a few months ago and I never received a questionnaire. (I've received them in the past.) I looked up my service history on https://www.toyota.co.uk/tme#/my-toyota/vehicle On the date I had the lower steering shaft replaced, it says "REPLACE LOWER STEERING SHAFT". On the date I took it for the upper shaft to be replaced, it says is "Please investigate clunking noise ***** " Looks like my upper shaft replacement was 'off-the-books'. Or am I just seeing a conspiracy when there isn't one?
