I got my TCH 08 in Oct. and have been generally happy with the ride except for: 1. The best I got in the beginning was 34 and now 23!!!- I was explained by the service tech that is very normal ! 2. The thermostat in winter time (with snow on the ground) when set at 69, registered 89.7 through the vents when verified by service dept- I was explained it is due to climate control jacking up cabin temp (for over 40 minutes ) but is very normal ! 3. The voice command occasionally works and after a long time does input a no. in the phonebook - again very "normal" since it works- "even if not to your" expectations: I was made to believe it!! I am truly confused - Should I give up the headaches and be happy with whatever left of new TCH??? I need some serious inputs!!! Thanks

Replying to: mra605 (Dec 20, 2008 5:18 pm) To all 3 questions the answer is yes it is normal, but let me add some explanations... 1) When it gets cold outside you will have a noticable drop in MPG. Several reasons are true for non hybrids as well. a) Winter gas, has less BTU per gallon than summer gas and this is due to air quality requirements made of the refineries. b) a small change happens because the gas pumps are 'normalized' to give you the equivalent volume as if the fuel was at ~70 F (check the pump next time and you should see it in very fine print) c) all vehicles are programmed to reduce emissions first, improve mileage second. This really hits us as not only does the gas engine (ICE) need to be at operating temp, but so does the catalytic converter. By needing to get and stay at a certain temperature, the ECU will run the engine far longer before it hits mode 4 (the mode where the TCH will run in EV mode) and then it will run again if the ECU senses that the engine or catalytic converter have cooled off. 2) the temperature that you select on the controls is a target for the ambient temperature in the cabin. So when you want to warm up the cabin from an unheated 30F to 69F, the car will push out as much heat as it can to try and get the cabin air to 69F. 3) This could be a fault with the system, or a piece of insulation in front of the microphone or it could be that your voice or enounciation is not within the programmed parameters of the voice command system. This is one where if the system is working correctly, you will have to learn to say what the system wants to hear.

Replying to: cdn_tch (Dec 20, 2008 6:44 pm) I am now wondering how come since 06, no TCH owner encountered such a drop in mpg and always managed to get higher BTU fuel during winter time! Also, the Voice command is a real joke! I have had the manager fumble a few times "Hitlering" the command center and finally succeeding in one isolated telephone number entry! He definitely knows the right enounciation and knows exactly what to say and how to say it - the way the system wants to hear! He indeed took his time convincing me how mine was better than that of other couples' system where he just had spent couple hours trying to make it work!

" to make you feel a bit better that you are not alone... With the voice command... I can't say that I am a fan of it either but it does work for me, but it is particular in how you 'talk' to it. A slower monotone helps the recognition. |

I'm new here but does the computer take into account gas savings when the eng. is shut off at red lights,stop signs etc.

Replying to: larsb (Feb 02, 2009 6:15 am)  i love camry and toyota in general - except i'm having same problem as mra605 dec 20, 2008, real world LOW MPG with my 7 month old TCH. i'm also being told by dealer and toyota customer service that vehicle is "running as it should". my MID displays 26-28 MPG ave. i've read a lot on this forum and others and honestly; who in their right mind would pay the extra cost of a TCH if they didn't expect to get EPA estimates or very close to it? to say to mra605 or any one else getting 5-10 MPG less than EPA estimate for TCH that it is "normal" is insulting. i am beginning to think these forums are biased/edited (to include only the most glowing reviews). OR toyota is ignoring a very real issue which is a high concern for certain TCH owners. this post is not targeted at larsb; simply a reply to last post relating to most recent LOW MPG post (mra605). i'm convinced i am driving TCH optimally. QUESTION REMAINS: does this forum contain ANY posts where people have had low TCH MPG and the issue was resolved by toyota? there was one case where a honda hybrid owner sued over less than EPA - anyone know the outcome? thanks |
