DI Failure Issue

its very hot out as well.

For those with an issue can you hear any engine whine or noise before the meltdown?

Mine makes a loud rattle above 5k under load 3rd gear, like firecrackers. I wouldn't call it whining its sharp and fast coming from the cowling area.

To me this is serious stuff, the community would greatly appreciate your planned video how-to I'm sure others are resorting to DIY just to avoid a disaster.

Even though I've worked on cars all my life a gas DI system concerns me a little as far as leaving the slightest leak causing a fire, the fuel is under a lot of pressure.

+1 Exactly how I would describe how mine sounded before the intense popping started in the engine bay. Mine will make the micro-explosions above 5k rpms in pretty much any gear 1st through 4th.

This was what caused me to trade in my FRS after 11 months. I started getting a machine-gun "popping" noise over 5k RPMs under acceleration pretty regularly, and I couldn't help but think it was "some new shit breaking". It wasn't incredibly loud from within the cabin, but it was loud enough to get noticed by passengers.

After reading the DI issue I got paranoid and just traded it in before I had Scion fight me again on yet-another-thing that broke on my new car.

We buy a Toyota sports car for one reason: Long Term Reliability. I don't mean the silly stuff like crickets, low on power, condensation in the tail lights, hard shifting into 2nd, that's fly shit . But detonation, blowing DI-orings and ultimately the losing the shortblock is serious stuff and word gets out.

You are the perfect example of how a new platform dies a quick death in the auto industry, resale will start to drop like a rock and new sales will follow.

So far the number or reported failures is minute in terms of number of cars sold. My rough math is showing about .0007% if you use this forum and North American sales only.

Folks, this is not an epidemic and there could be so many other factors contributing to this. Nobody honestly knows. If you are this concerned about it and cannot wait for a fix (IF there is ever a fix, and there may not be based on rate of failure) sell the car and move on to something that is more reliable. If that even exists.

Except, according to regal, you bought another car that will have an exploding engine.. Subaru engines are the problem.... I would sell the STi and get a Prius ASAP.

I didn't know we had an actuarian on the forum. Good to know I'm in the 99.9993% percentile I feel special.

"Special" is one word for it I guess...

Looks like I will basically be driving it like a Prius until they get this sorted out. No more WOT, no upgrades that could be used to void warranty by dealer, just a bone stock car driven like only an old man would. Will make my wife very happy, but it makes me sad

Then you haven't understood the nature of the problem and are reacting to doom-mongers fear posts on this forum. There is no problem with driving at WOT.

Either get the latest 01x calibration from your dealer, alternatively the workaround is to stop snatching gears at light-speed near the redline.

Wouldn't it just be "actuary" ?

There are guys on this forum who have 10-30K+ miles of driving spirited (and some of that includes lots of track time) that have not had DI issues. Does that mean you won't? No. But the likelihood of having them is much less than not having them.

IMHO, drive the car spirited. If the engine explodes, well, you have a warranty.

Just under 30K twins have been sold in North America. This is based on the sales numbers provided to the public. If you can provide me the number of DI failures in North America, I would be happy to do the math for you. There have been something like 22 posted on this forum (which is accessible outside NA). Even if we say the number is 100 people, the precentage is still .003%. I find it hard to believe that more than 1% of all cars have had to get their DI's replaced by now. The Internet would be blowing up.

Can it happen? Yes, we know it can. Is it likely? No. Should every FR-S and BRZ owner be worried everytime they drive their car that the engine will blow up? No.

I understand you are obsessed with this issue. I applaud those that are working to get this issue researched and fixed. I truly feel for those that have had DI failures and can only imagine how frustrating it is. But let's please try to use commonsense and stop the doom-mongering. It is not helping anyone.
