Hi guys,

I bought 2 weeks ago, taking advantage of the last days of the 2.9% offer, a brand new Corolla Ascent Auto. It seems like an awesome little car, but I noticed a few "issues" that only you "experts" can tell me if they are normal or not. I would be really grateful if you could give me an answer to the following:

1.

On a city cycle (not always busy, also going around in the night or short parts of freeway) the average fuel consumption is 12L/100Km... that's what the computer tells me and the same results from my calculations... it seems WAY too much? Is it normal? What can it be?

2.

When 2nd gear enters the engine simply doesn't give power.... 1st gear is pretty fun to drive, but on the 2nd gear at low rpms the car doesn't accelerate promptly even at full throttle! What can it be?

3.

The automatic-folding rearviewmirrors are not so automatic. Basically as soon as I remove the key the button doesn't operate anymore... it's very silly because if I fold them before being ready to leave the car, I'm not able anymore if there are cars coming from behind... I would have expected to be able to fold them with the car off or, even better, automatically as soon as I close the central locking with the key or the remote...

Thanks in advance for answering to some of my questions!

... and pleased to be part of the club!

12L/100km doesnt sound right. That'd be all out hitting redline through your gears all day everyday. How many km's are you getting from your tank? 500-550km is about normal in mixed conditions. Think i average 6.5L/100km. The average fuel consumption reading isnt always accurate, but if you want, reset it (hold the button in for a few seconds) before you drive for the day (resets it back to 0L/100km) and see what it is when the day is through.

I have manual transmission so i cant comment on the changing of 1st to 2nd gear in auto.

And i dont have auto-fold mirrors so can comment on that either. sorry mate.

If you bought it two weeks ago should be with warranty.. Take it to Toyota see what they say?

But yeah thats way too much fuel consumption, my Rav4 V6 doesn't even use 12L/100km..

Your fuel consumption sounds very wrong a friends of mine has the same car and he was getting 7.5L/100km city driving...

That's what I would expect, as well. I tried to reset the thingy 3/4 times and the average on 50-70kms always comes out around 11.5-12L/100km and the calculation made on the litres/money spent gives me the same answer, so it's not just a matter of "tuning" the computer. It just drinks a lot!

How does that computer calculate the average consumption? On the basis of what kind of parameters?

I have to take it to the dealer for the 1st month free service in 2 weeks. I will raise that problem for sure...

Any idea about the lame 2nd gear???

i would definately be telling them at your first service how many km have you done i know that once its run in it shoul drink that much but 11.5/12L to 100km is a bit too much for my liking for the 2nd gear issue when you change from 1st to 2nd what do you mean that i just doesnt want to go it sounds unusual for it to be slugish in 2nd reslly shouldnt be like that...

yup, its auto gear, but it kicks in very well when I start at the light for example, but it dies when it puts in 2nd gear... that's wat I mean. As soon as it goes up with rmpms again it goes better, but 2nd gear at low rpms is very slugish...

Like Johnnie, I drive mine quite hard, and the most ive ever hit was 9.8L/100... 12L i cant see happening unless you at redline every gear change and going 150+ everywhere..

This is abit different but about the gear change. Whenever i drive the Yaris and change to second (its manual) it doesnt really go either, even when its flat on the floor. Though its a smaller engine, Im guessing theres just no torque down in low rpm?

i would like to add as well my car does around 450kms on a full tank and the avg fuel consumption is around 9.4 more or less depending on how i drive. also wondering if that's how the car really is, i kinda expected better result but seeing the newer 2010-11 models the specs says 9.7 city urban driving, so does that mean i'm doing ok? :blink:

my avg is around 10.9 city but thats because i drive like its stolen... high way i get 6.9

mums got the new ascent her avg is around 10.2 and she doesnt thrash it at all i dotn think she ever shifts past 3k rpm so i rkn its got something to do with the tranny i guess if your foots always lightly on the pedal your constantly using fuel how ever if you step sligtly harder and roll alot more you will end up using less.. thats what ive noticed. you can try it out just look at the active fuel consumption metre when driving.

side note my fried has a auto conquest and he manages to get 7.8-8.3 city.

Think max i squeezed out was 620km with super grandma-spec driving. *was trying to save petrol and max out my km's* lol

350-400 seems quite low for a new car. Being 1.8ltr as well, should be quite economical. Try doing a days worth of highway/freeway driving and see what your average is, and how many kms you squeeze out.

My old 93' Celica got 350km a tank, because i had a lead foot. And 400-450km when i baby'd it.

This morning I called my dealer to ask about the fuel consumption issue and he told me that it takes a couple of full tanks in order for the engine to settle.

I will bring it in in 2 weeks for the complimentary service (1st month) and will see. Anyhow today I filled up the tank and will make new calculations, but dealer's explanation didn't really convince me... 12l/100km just sounds WRONG to me... even if it goes down to 11 it would anyway be way to much for the way I drive the car.

I have the Ascent Auto. You are right. First gear is fine then at 2nd gear low RPM's is sucks balls. I floor it and doesn't go anywhere until it comes past 3000RPM then it kicks in.

Make a list of all the issues your having so that way when you book your car in for the free 1000 Km "Service/Inspection" you can tell them all the problems your having...

That does sound a bit high. Like others have said above, check it out with Toyota when you do your first service or even as soon as you can (if you want).

Another option is to reset the ECU? Just a suggestion!

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.
