  1. The air conditioning compressor is driven by a 230v motor which is powered from the main hybrid battery. So I don't think the ICE needs to start to run the AC. By contrast, in conventional cars the compressor is driven by a belt from the engine; so the engine needs to be running to have air conditioning. If the engine starts when the car is stationary in warm weather it's because the battery is getting low and needs to be charged. After running for a minute or two it will stop but the air conditioning continues to work, powered by the battery. On cold days, however, the engine will run to provide heat in the cabin. If you turn off the heating the engine will stop sooner after startup, If you turn the heating back on, the engine will start immediately if the coolant temperature isn't yet high enough.
  2. Here's a page that might be useful. It's about the 2010-2014 Prius and code 3004. I wonder if the 2012 CT200h is mostly the same mechanically and electrically. The page says: P3004 TOYOTA - Power Cable Malfunction Possible causes Faulty Inverter With Converter Assembly Inverter With Converter Assembly harness is open or shorted Inverter With Converter Assembly circuit poor electrical connection Tech notes Toyota recently released a warranty enhancement for 2010-2014 Prius, extending the coverage of the inverter/converter Intelligent Powertrain Module. Toyota Bulletin Information: Toyota has received some reports where the Intelligent Power Module (IPM) located inside the inverter assembly of the hybrid system may fail. This condition is indicated by hybrid system diagnostic trouble codes (DTCs): P0A94, P324E, P3004, and/or P0A1A. If one or more of these DTCs are detected, various warning lamps on the instrument panel will also illuminate and the vehicle will enter fail safe mode. Although the Hybrid Inverter assembly is covered by Toyota’s New Vehicle Limited Warranty for 8 years or 100,000 miles (whichever occurs first), we at Toyota care about the customers’ ownership experience. Toyota is now extending the warranty coverage for repairs related to failure of the Intelligent Power Module (IPM).

  3. Small children sitting in cars or planes like to kick the seat in front of them. Can anyone recommend a product that will protect the car seat backs from muddy wellington boots? In particular, to fit an IS300h.
  4. I haven't been able to find any terms and conditions for the hybrid health check warranty in the UK. But I did find this page for the general warranty in the US. This says battery and inverter are guaranteed for eight years in the US. They're listed together as though they're regarded as a functional single unit. Also found this old discussion about inverter failure which says Lexus UK paid for a failed inverter as a goodwill gesture. But obviously, you need first to establish that it really is the inverter rather than something more minor.
  5. In any case, if you've been having the hybrid health check done with the annual service, the resulting one year warranty may well cover the inverter as part of the hybrid system.
  6. Here's a Prius chat page that also suggests cable malfunction and relay malfunction for this fault code. The car in question seems to have been under warranty so the easy option for the dealer may have been to replace the inverter and charge it to Toyota. But maybe that wasn't actually the problem. Looks as though it may be worth investigating less expensive issues.
  7. My guess is also that it's to do with the e-CVT. This page shows how the e-CVT works. If you scroll to the bottom of the page there's a simulation where you can adjust the speed of the electric motors and the internal combustion engine (ICE). Although this simulation is for an early Prius, the principle is the same. When you adjust the speed of the car on this simulation to 20 mph, you can see that the maximum speed for the engine is around 2600 rpm. This is because at these speeds the MG1 motor is already hitting its maximum of 6500 rpm. Any faster would cause damage to the electric motor. When you increase the car's speed to 30 mph, the computer now allows the engine to speed up to around 3000 rpm. But at these speeds, MG1 is still spinning at its maximum 6500 rpm, so the computer doesn't allow the engine to go any faster. So my guess is that this is why it takes a while on the IS300h to get the engine up to 6000 rpm - MG1 is prevented from spinning faster so that it isn't damaged. And that in turn forces the engine to build up revs gradually in line with the road speed.
  8. I don't know. My guess from the wording from the manual is that if she uses her phone she would be able to make separate recordings of names of the contacts on her phone. But I'd be surprised if it worked if she tried to make a call on your phone - unless she could do a good imitation of your voice!
  9. It's actually quite useful to be able to say someone's name to call them. I didn't bother with this for a year or more as people on forums said the voice recognition is hopeless or non-existent. But I eventually decided to investigate it and when it's set up it's an easy way to phone people without having to look at the screen. It isn't very sophisticated, in that it doesn't do voice recognition like in dictation software or Google/Amazon internet based voice recognition. Instead, you have to record yourself saying the names of the contacts you want to use. It doesn't help that the process for doing this is difficult to find without studying the manual and you also have to know that the Lexus terminology is "Voice Tags" that you record for each person. But when it's set up you just have to press the button on the steering wheel, say the name, and then press dial. It's actually quite handy, when set up. On balance, I've found it worth setting up, even though it has limited use eg. you can't use it to select music tracks, only to phone people in your contact list. You only have to set it up once. This is how the manual describes the set-up process. (They really mean, "say the contact name" I think.) Then the manual decribes how to make a call using a Voice Tag.
  10. It's interesting to see that the Which? magazine in its latest annual car review gives the IS300h the top score in its class. But they continue to say it had high carbon monoxide emissions based on the test they did in June 2013. I'm still inclined to think this result from six years ago must be suspect - their mpg figures for urban and motorway use are clearly nonsense, You would think that after so many years they would publish how they achieved the figures in 2013 or at least retest in order to compare with the very different EQUA Index figure.
  11. The belt in the youtube video looks as though it's from a conventional cvt (like the Mercedes B class?). The speaker points to the two pulleys that are linked by the belt. The Toyota/Lexus e-cvt doesn't have any belts like this, just cog-wheels that are permanently engaged. Having said that, I can't find which version of the transmission is fitted to the ES. The IS 300h and GS 300h have the L210 transmission. (Here's a list of transmissions on Lexus cars.) The L210 is a modified version of a Prius transmission, from memory possibly the P410. The difference between them is that the P410 is for front-wheel drive and the L210 is modified for rear-wheel drive. But they have no belts, rubber, steel or otherwise. The ES has a front-wheel drive version of the transmission - (is it the P610? I can't find any reference to it). I think, again from memory, that it uses faster spinning electric motors that remove the need for any extra reduction gear, making the unit smaller, and thus able to fit in to the front wheel drive configuration. But the absence of the reduction gear brings the lower top speed - 112 mph instead of 125 mph with the L210. The electric motors would be damaged if they spun any faster. But I'd be surprised if the ES transmission has any belts, rubber or steel. Maybe someone who has an ES300h could look on the car's VIN plate. The transmission version number will be on there, probably beginning with the letter L or P.
  12. Glad to hear it's all been sorted out. I hope Halfords paid the full cost. But if untrained store staff use the recommendation on the Halfords website, they'll still end up selling and perhaps topping up air con gas with the wrong and dangerous product. I've tried putting the model details of a couple of Lexus hybrid cars into the recommendation page and it still comes back with the wrong product. Although the detailed information pages and the products themselves are marked that this product must not be used on hybrid cars, some people may not read that far. They've already had the recommendation from Halfords. Why read further? The staff member you dealt with didn't read what it said on the canister. In fact, they may not have even known what a hybrid car is.
  13. I'd recommend this too. I had various digital gauges before but I found them much more of a hassle to use. Turning them on, resetting to zero, a bit small and fiddly. By contrast, this is robust, well-made and seems to be pretty accurate. While you're at it, I'd also recommend this tyre tread gauge. It's much more accurate and easy to read than those pencil type gauges that have barely any movement for each millimetre of wear. Also available at Amazon.
  14. Don't worry. The DAB radio is just very badly designed. A pity on a car where most other things are very nicely designed. Have a look at this discussion from earlier this year It's possible that the 19 plate model is different from the earlier ones. But if not, you should be able to find the answer after reading through the discussion. If you're still stuck, I'm sure someone will be able to help.
  15. As it probably comes under the heading of consumer affairs, the "Which? Legal" service might be helpful. I have no idea what they're like and have never used them. But they ought to know about the issues that arise when buying products that cause problems and what your rights are. You can also talk to them on the phone, whereas the Citizens Advice Bureau seems to involve going to an office and waiting around for a long time. For example, they have a template letter on the website that can be used when a car is damaged while being worked on. This seems to be the case here.
