  1. Hi All, I have a late-2013 Yaris Hybrid which makes an odd noise when I go over road humps, but only under specific conditions. There is one particular section of road that I travel regularly which involves stopping for a junction, turning right into a 20mph zone, a short acceleration up a hill before reaching the first road hump, the sort with a flat top about the length of the car. As the front wheels rise onto the hump there is a clonk sort of noise followed by another one when the front wheels go down the other side. Continue up the hill and the same happens again at the next hump, but there is no noise from later humps as the road reaches the brow of the hill and goes down the other side. The noise is consistent and reproducible at this spot but hardly ever occurs anywhere else. Does this story sound familiar to anyone? Graham.
  2. An update on the story...... After I took the voltage readings early in September (see above), son informed the dealer and arranged for the car to go in for the fourth time. He also took his record of over twenty failures since his previous visit but again the garage tested the battery and said it was OK. This time though they did agree to change the battery anyway and there have been no failures since. Problem solved.
  3. Update. I had the opportunity to check my son's battery today and found it very low. After a short run followed by 20 min rest the standing voltage with all load turned off was 9.8v and it dropped to 9.0v for an instant when the start button was pressed. This time it did start without a problem and the voltage rose to 14.3v. Armed with these figures he is going to go back to the dealer to get them to replace the battery. Michael - it's a 2011 Gen 3
  4. Thanks for the suggestions. The video is pretty much what I remember from watching my son trying to start it at the weekend, and I see at the end of the thread the problem goes away after a new battery. The only battery test we had time for was to try lowering the windows when the car wasn't showing Ready and they seemed to work as normal. I'll send him a link to this thread and see if we can have a closer look at things next weekend. Thanks again.
  5. Hi, My son is running a leased 2011 Prius with about 35,000 on the clock which has developed a strange problem that I hope will ring bells with someone. Starting with a cold engine is fine but if the car is stopped it won't restart when warm, even if it's only had a short run. When the Ready button is pressed with the brake pedal down it goes through flashing all the lights on the dash but then shows the amber light on the Ready button and doesn't show Ready on the dash. If he repeats the operation it does eventually start but yesterday it took 28 presses to get it going after a run of about 2 miles follwed by 20 minutes rest. It's been in to Mr T several times and they have checked the 12v battery and replaced the brake pedal switch. They now seem to have run out of ideas and have asked him to record when it happens in the hope that they can see a pattern. Any ideas?
  6. My Prius on 17" is lumpy and rattly.
  7. Hi Guys, Sorry for not responding sooner - we're on holiday for a few days in God's Own County and haven't been able to get on the internet. Thanks Kingo for confirming that mine should have been done in May - I'l get on to the dealer when I get back home. As for location, we spend about half the year in UK and half in France but for everything official we are still UK resident. I'm on other forums that do allow you to add your own words for location so on those I put Berks UK & Gard FR - much more helpful.
  8. Can someone please tell me when the HHC was included in the service. My Prius was serviced in May and the service sheet lists the HHC but it wasn't ticked and I didn't get any sort certificate for it. Thanks.

    New To The Prius

    Hi Simon and welcome to the forum. I don't think anyone has mentioned the Power and Eco buttons. The main effect is to alter the response of the accelerator pedal. Eco will make the car feel very slow until you get used to it, and Power will have you taking off like a rocket. My technique is to run in Eco mode all the time except where rapid acceleration is needed such as joining fast-moving traffic. There is also a Normal mode which, as you may expect, is halfway between Power and Eco. There's no Normal button as such but you get there by pressing the Eco button again if you are in Eco (or the Power button if it's in Power). I only use EV to stop the ICE (i.e. the petrol engine) starting if I'm moving the car a few feet on the drive. It only saves a drop or too of petrol but as someone said you get obsessive about mpg with these cars. Happy motoring.
  10. I once went to a conference on software quality where one speaker said that the worst code they had analysed was from a nuclear power station - scary.
  11. That Jeep is so ugly nobody would want to steal it.
  12. Another vote for Firefox. Haven't used IE for years.
  13. The ethanol fuel started to appear in France about 10 years ago and is safe to use in your Prius. However I generally avoid it personally because I find there is a reduction in power and increased consumption which more than offsets the slightly lower price. Most branded petrol stations have gone over entirely to SP95-E10 but supermarkets still stock SP95 which is my usual choice. The majority of supermarkets are closed on Sunday but have automatic pumps. I've heard that some credit cards don't work in France but I believe these are Amercan-issued cards and I've never had problems myself with Mastercards or Visa. You can find fuel availability and prices at each petrol station on this French government website http://www.prix-carburants.gouv.fr/
  14. An article I bookmarked some time ago (http://techno-fandom.org/~hobbit/cars/sweet/refl.html) comes to the conclusion that "One of the core efficiency techniques is to use the gasoline engine as productively as possible, or not at all. That's the essence of the "pulse and glide" routine, and plays on the simple fact that the typical internal-combustion engine is *not* very efficient when driving light loads. If you want the best output for your fuel dollar, you have to make it *work* against a load but not against itself, which means high output shaft torque but at fairly low RPM. As non-intuitive as it sounds, trying to baby an engine generally does not return its best fuel economy -- for the moment discounting special cases like lean-burn designs" The author then goes on to explain how he arrived at this conclusion with a few thousand words and numbers. If you have the stamina it makes interesting reading. Unfortunately the source isn't identified so it's difficult to judge if the info is reliable.
  15. You're kidding? When we were in France the other year we just programmed the SatNav to avoid tolls and we only paid 1 toll in the entire trip and that was because I wasn't paying attention. You drive along, about a mile before the toll signs the SatNav says turn off, you turn off the motorway along with all the French cars, drive along the old route with the motorway still in your view, a few miles later you pull back on and away you go. Simple. Was fun to watch all the Brits whizzing along without noticing, presumably around the corner they'd see the Peage sign and grumble. The turn offs everyone else pulled off were usually weakly signed and certainly didn't give a hint you could avoid the tolls. Sometimes you had to drive through a nice small town, but they were never gridlocked like here. The side roads were also like UK side roads used to be 30 years ago, wide enough for 2 cars but no white lines and no curbs. I think it's been a long time since you've driven down such roads in the UK as now they are as rough as a cobbled street. Literally pot holes ever few yards, worn out ruts, holes, sunken old roadworks, drain covers sitting proud. Nightmare, Dare I say you had your rose tinted specs on with your comment? My main reason for using the French motorways is that it's so much faster. There are very few parallel roads on my route that have a speed limit above 90kph and it drops to 50kph as you pass through each village. On the motorway I can maintain a fairly consistent 130kph (admittedly with the dramatic drop in MPG mentioned in the original post). You pay your money and take your choice. I'm not sure which comment you're referring to in the last paragraph. Local roads in both countries are maintained by local authorities who each have there own priorities. Maybe we're the exception, but I don't find the roads where we are in the UK anywhere near as bad as you are describing. The lack of white lines, cat's eyes and edge markings on country roads seems to be common across France and can be a real menace at night when there are oncoming headlights. Another good reason for sticking to the motorways.
