I sat in a lush green area at a complete standstill today. The cricket chirping was perfect for making the car one with nature. Gave the plants a nice soundtrack to go along with the rustling of the leaves. This is the greenest car I've ever driven and plan to drive. All them Priuses are just posers. Good job, Toyobaru!

I put in a service request w/my dealer to investigate and complain about the many issues I'm experiencing with this car. I recommend everyone do the same as well.

Here is what I wrote to them:
Traffic on Nav Not working. Engine has a high frequency Squeal/Chirp. Car has rough idle (idle will fall to 400-500 rpms frequently and shake the car). Fix Rattle coming from trunk area. See if any codes were pulled from a slow start.

Oops, forgot about that. One of the few things Toyo did...

Don't feel isolated, those are the same issues nearly all of them are having so you are not alone and it should be well known to all the dealers by now.

As for the rattle, you must find it before you bring it in otherwise they'll do nothing or tear the car apart searching for it. It's always best to discover the exact source and location of rattles beforehand. Don't ask, tell instead.

As posted on another thread but this topic has spread so it's not getting through. This sounds the real deal below and if it is, a splash of 2 stroke oil, high quality, in the tank should prove the point. Say 100ml just before filling up for 1:500 in the 50L tank, so it's just a light dose of lubrication simlilar to what the Japanese fuel might have? Not 1:40 or anything like that. Hopefully that will almost instantly shut the dry washer up unless it's too stuffed?
If this is the problem they will have to modify the HP fuel pump to cope with the US quality fuel.
I'll leave you guys to work in out in the measures you use over there.
It's just to prove a point and hopefully shut it up until they bring out the fix.

FRS direct injection fule pump problems.

Just wanted to give you all a heads up. I had to replace this pump today due to the fact it was making a loud chriping noise almost like a wet drive belt. The toyota reps came out to my work and listened to it. It only happens once the temp gets to around 140f. They explained it to me as follows. The pump has a washer inside of it which if not lubercated properly it will make that noise. They said that Japan gas is way better and has more lub in it the USA gas. SO the usa gas casued the washer to not be lubed properly. There is no known fix or TSB for this. i got a new pump but keep your ears open so you can catch it and report it. Its not a preformance issue jsut an annoying sound thats all. Hope this helps.

from what you said, then we are all screwed. WE cannot just import jp fuel for the fr-s.

We are just gonna have to cover our ears, until, they figure out how to lub washer?

[Razz]

So you have to add pre-mix just like the Rotory engines.

Oh well...

That's just too bad, as no other manufacturer can make a fuel pump with out chirping.

Intriguing.... Mine's pretty loud. I'd love to do something to silence it but I don't know how even a little 2-stroke oil would effect other aspects of the fuel system/engine.

It may be harmless but without knowing I'm not comfortable.

[Indestruct]

This is ridiculous, so we're all screwed basically? How hard is it to get a fuel pump that actually works...

[rice_classic]

Is this just annoying or is a symptom of impending failure? I imagine something that needs better lubrication (like that from JDM fuel) and doesn't receive it the results would be eventual failure. That's my concern.

If there's a little "chirp" at idle but the pump can last for 300k, I wouldn't worry too much. However, if the "chirp" means my fuel pump could fail at 20k when I'm in between Seattle and Spokane then yeah.. I want that remedied asap!

[Marrk]

Does anybody know for a fact that there is any significant difference between JDM fuel standards and USD fuel standards?

This fuel type difference does not make sense. How can 20% of the people reported no issue? Did they use octane 94? How can we get ourselves into the 20%?

I have a GTS 86 on order but have been driving a Mitsubishi Triton single cab with a 2.5 common rail direct injection turbo diesel for the last 3 years. The low sulphur content diesel lacks the lubrication it used to and the pumps have had to be designed with that in mind.
To be safe I have added 2 stroke oil at 1:200 since it was new with the only side effects being a quieter engine, and slightly better fuel economy.
2T is designed to disperse in gasoline, provide lubrication and burn cleanly.
What is the lubrication in the Japanese fuel that 'some?' of yours lacks?
Personally I would give it a go as being the best choice until they fix the problem but I can understand others hesitating but then I have a technical background. Think of all the other additives that people throw in the tank without really having a clue what they are?

From reviewing post in this thread, this issue seems to be unique in usa. It could also be that there are a lot of frs in usa.

In general, there is no issue for people in canada using high grade fuel, ie 94 octane.

Can people confirm if this is true?
