Idle issue?

[Mcdj18]

I got my car back today from the dealer. It seems that's they are aware of the issue however they told me there isn't much they can do right now because Toyota themselves have not isolated the issue/issued a fix. The car is safe to drive which is the most important thing, but the chirping is very annoying. We'll just have to wait and see how this play's out. The best thing to do if you have the chirp is to bring it to Toyota, Scion, or Subaru and express your concerns. If enough people complain, it will leave headquarters no choice but to respond with a fix or recall.

This question was hammered early on. It's definitely not the gas. Guys are experiencing this after several fill ups.

I don't know if this is a related issue but my brz had a hard start up today. The engine just kept turning over for what felt like forever and my car finally started. Usually it fires up right away. I used the push starter so I know it wasn't user error!

A subaru guy driving up for toyota?!? Is this one of the signs of the apocalypse?

Kidding aside I said this exact same thing a few pages ago. The idle issue is most likely not a DI issue. A famous man once wrote "don't panic". I was one of the first who were posting about this, and I even had a few clear missfires. I stopped by the dealer and reported it, but continued about my day.

Until a CEL is thrown there isn't much to do.

my 240 liked to dip in the idle..its a MAF thing. i prefer map sensors but there also harder to tune from.. could be minor leaks after the maf sensor. id check the coupling to the throttle body

First post, to chime in...My FR-S is about three weeks old, about 500 miles on it. Second tank of known gas (filled by me, not the port of entry, or the free Dealer fill-up).

It's had the rough idle issue. Happened twice. The second time, it dipped to about 300-400 RPM, then leveled out. This was at a stop light after 10-15 minutes of city driving. It's always a bit rough when cold.

It also chirps. But, after freeway driving in high heat (where I live, it's been upper 80's during the day).

No CEL's

Decided to take it in, mainly for documentation purposes. The Dealer only had two mechanics trained on the new engine, so they consulted with the "Lead" Scion techs. They said the chirping was the Direct Injection bleeding off pressure. As for the idle, they noted it in the Case File, but nothing was found.

I've driven it pretty hard, and no other issues have creeped up with the engine. My first to second gear synchro, though, can be a bit rough.

Food for thought: The last first model year car I bought was an '07 Mazdaspeed3. The big scare story for that car was the failure of motor mounts, which could cause the engine to, literally, fall out. Mazda eventually issued a TSB for it, but there was only a few reported incidents. Also, that car had a bit of a rough idle, which was more of a perceived problem inside the car, so some aftermarket tranny and engine mounts became popular to curb the cabin roughness. Seems the internet always fuels some fires, I guess.

Maybe. But that's a hell of a way to run a country.

Keep us posted on this.

That's the most interesting explanation I've heard yet.

It's one that had actually been stated before when the chirp had first shown up, and who says I'm running a country, I bought a car.

My theory is that my issue is reported and there are more severe cases out there that are being looked at. I'm proactive about following the issue and logging instances, but until I throw a CEL there is nothing they will learn from my car they can't get from whiteout's or the other 2 vehicles that have thrown CELs. I would just be wasting everyones time...including my own.

If this is normal for DI, then the many other cars with DI must chirp as well. Audi, Honda, VW, etc.: Do they chirp?

I understand that you cannot do anything without the appearance of a CEL. However, a system in which a trained factory mechanic cannot do anything without a CEL is a system that, perhaps, needs to be rethought.

With respect to the way you are pursuing the issue with your car, I'm sure you're doing the right thing. On the other hand, maybe a different tech at a different dealership would get farther than the ones who worked on whiteout's and the 2 vehicles that have thrown CELs. Maybe not, but maybe.

In sum, this kind of problem is typical First Model Year stuff. If and how well they resolve it will determine the success of this new, well-advertised "driver's car."

As I sated in the other thread about this issue (which is honestly where this discussion should be taking place. This thread is about idle dip and CEL's and is completely unrelated to the chirping sound. Which there are like, 10 threads about because nobody knows how to use search :sadface: EDIT: No offense meant to anyone in this thread, I definitely understand the concern!), I have an 08 Mazdaspeed 3 with DI and my car made the same exact chirping noise (not quite as loud, but it was definitely there). It went away when I got an upgraded HPFP (which was NOT due to any failures on the stock pump. The stock pump was fine, and ran the car for 50k miles before I replaced it for tuning purposes.).

I don't make any claims to be a skilled mechanic, but I've poked around the engine bay with a stethoscope and the sound does indeed appear to be coming from the HPFP. At the least, that's where it's the loudest. Grain of salt, though.

The Subaru corporate rep will be at my dealership today so I'll be asking him about it. Gives me an excuse to drive the hell out of the car on the way so it's making the noise when I get there

Many have commented about the synchros. Gears 1-3 are triple-cone so a bit of resistance early on appears normal. Most said that by 2,000 miles or so the tranny smooths out quite a bit.

Do we have this documented? If so, I'd like to see it.

Gonna post this in all the idle chirp threads I can. Just got back from the dealership where a Subaru corporate rep was taking a look at my car due to front bumper fitment issues, and I asked him about the chirping noise.

He says they've been holding classes for techs on the new motors, and their demo cars are all doing it. As of right now, it's a known "issue" and it's been logged that people are complaining about it. This is what he had to say about it.

"The issue has been classified as a normal noise to the Direct Injection high-pressure release valves when operating under normal conditions. It's intermittent in that the DI/PI systems work in tandem, and it will only generate noise when operating under specific circumstances which are most likely at engine idle. Every single car (Scion, Toyota, and Subaru) will emit this noise at some point in it's life. There is no current plan to investigate a fix unless enough people whine about it."

More or less a direct quote. Yes, he said whine.

They logged a report on the issue saying that I found the noise detrimental. Cars are noisy and I'm not gonna get my panties in a bunch over it, but FOR YOU GUYS I told him that I "didn't mind either way, but I guess I would prefer if it didn't make the noise."
