Aussie MY22 GT with zero turbo boost

[Maxmad]

We have had our GT for about 2 months. It has 2500km on it. It has no mods at all.

Last night we set off on a 90 minute / 120km drive. Early in the drive I noticed that acceleration seemed sluggish - but didn't pay too much attention at first as I was experimenting with drive modes and figured that I had caused it with ECO or Smart (first time ever using Smart). A little futher on I had the opportunity to do a 0-100km/hr run. I put it in Sport, disabled traction, floored it. The noise and revs and gear changes all sounded normal ... but the car was SO slow. I checked - and it did 0-100km/hr in just under 11 seconds (not quite the sub 5sec times we had become used to!).

Next thing I did was bring up the little triple gauge set (the ones with Torque in the centre and boost on the right). I floored it - and torque registered, but there was zero boost. Not wanting to tempt fate (pulling over at the side of the road and restarting) - I drove home, turned everything off, unpacked the car, then restarted it to see if the problem was permanent or temporary. Fortunately - it seems that it might have been temporary - as my boost was back and the wheel spinning acceleration was as good as it had ever been.

I've heard of a few folks mentioning a similar thing on occasion - so I guess my question is this. Has anyone had this happen - and then magically resolve itself on a restart - but then had it come back to haunt them again later? If so - what ended up being the cause? Alternately, in your experience, was it just a one off that you never found a reason for (and that I should just chalk up to some strange confluence of events - or the Stinger teaching me a lesson for daring to use Eco and Smart modes)?

Thanks a lot.

Another 2022 losing boost. I wonder if Kia acknowledges this problem…

Some say it's traction/esc. Some say it's build up in the blow off valves. All I know is that my car gets it and it's not a my22. It does go away after a restart. I can very much make it happen on demand. All I have to do is make a sharp turn in comfort mode with all the nannies on over some rough pavement. 99% guarantee that I wont have any boost for the remainder of the drive lol.

 

[Maxmad]

Interesting that you have found what causes yours. Other than using SMART and ECO for a short time, I did nothing different to any other time that I have driven ours - so unless there is a MAJOR bug in smart / eco, I am yet to find our cause.

Note that ours DEFINITELY experiences big time intervention from the traction control if you leave TC active and try to accelerate fast from a standing start (slightest bit of wheelspin and the car intervenes big time - robbing me of my beloved acceleration) ... but that is not what was occurring last night. Last night was no boost - anywhere in the range. I tried from start - no wheelspin - no boost. I tried at 100km/hr - flooring it to see whether I would get any boost - and there was no boost and very poor acceleration - so it seems that in my case there is no connection to traction control.

My word. This is becoming a weekly instalment. Some experience it with an aftermarket exhaust, producing too much boost, bam, limp mode until you do a restart. But the "no mods whatsoever" club is increasing in numbers, as I say, seems almost one a week anyway. And no, nobody has come up with any singular cause to complain to Kia about, and "fix this". This is a developing thing. It's good that you can avoid it mostly by turning off TSC. So, if you want "beloved acceleration" (my sentiments precisely), go straight to Sport mode and turn off TSC. Report back if you lose boost again doing only that.

That's the thing. It could have triggered before you did your launch attempts. Once it triggers you don't get any boost the remainder of the drive. Even going over a small dip in the road can sometimes leave me with no boost if I try and power through the nannies kicking in.

Thanks Merlin. I think I may have muddied the waters a bit here. Apologies for that.
I have two completely separate "issues" (occurrences?):

1. TSC cuts in way too early and way too aggressively when accelerating briskly. It can happen on uneven / corrugated surfaces, slick surfaces etc. It can happen from a standing start OR from low speed when it kicks back a gear and breaks traction. This seems to be something that everyone experiences when they accelerate hard off the line. It is something I gather we all learn to live with. In some ways it is almost a good problem - as it is only happening due to the crazy amounts of acceleration on tap once the turbos kick in. The best part is that it is easily resolved by turning off TSC.

2. Yesterday - in a single isolated event (so far anyway), for some completely unknown reason, I lost all turbo boost for the duration of a lengthy drive. It has never happened before - and I can't see any link between this and item 1 (TSC) above. This is more of a worry - as it came from nowhere - I can't think of any event that could have triggered it, and it required a restart to make it go away. If it is a one off glitch - then I'm good with that. Stuff happens. I just worry that if it can happen once, it can happen again.

For anyone else who has had problem 2 - complete (temporary) loss of turbo boost - can you think of any factors which preceded this? Like General_Vodka and going over a dip? Or in my case - fooling around with SMART mode (surely not the cause - but interesting that my first time using SMART mode coincided with my first time losing all boost). If it is happening to someone somewhere every week, then perhaps we can start to gather info on the situations that preceded it, and look for overlaps.

Also - I will definitely report back if Sport Mode and no TSC causes a loss of Turbo boost.

2022 3.3 GT2 AWD CEL Today - No Mods...

My 2022 3.3, bone-stock, threw a check-engine light today, with a message about the ECS. I also lost all boost. I turned-off the car, restarted, boost returned, but CEL is still on. It happened after moderate acceleration, maybe half-throttle. Is there a way to find any codes thrown? Any...

stingerforum.org

I've lost boost 4 times now, and each time it was when the engine wasn't fully warmed up.

@ScorpionStinger goes a little further and states that when his oil-temp is 150+, he no longer loses boost, so I'm going to be careful and make sure my oil temp is fully warmed and see what happens. Hopefully this simple 'trick' will work for me too.

Was your engine fully warmed-up when you lost boost?

Yeah I don't think engine temp plays a part in my case. Doesn't really matter if the engine is cold or hot, it happens regardless.

 

[Maxmad]

Agreed. My temp was definitely fully warmed up when I first accelerated hard and noticed the issue (I had probably been driving for 15-20 minutes). The only completely abnormal thing about my occurrence was that it was on a trip where I drove about 1 minute, then saw some friends and chatted with them while I left the engine idling for a good 5 minutes. I normally would not do that - but I thought it would be a 30 second chat and it just went way longer than expected.

So - mine is not temperature related, but occurred after a 5 minute idling session, and after playing with SMART / ECO.

Also - no CEL for me. I even scanned for codes later (in case I somehow missed one) and the car has not thrown a code or CEL since new.

I also have a 22 Stinger with boost problems. It happens in all situations. Been to the dealer about 10 times with it. When it has happpened
I have taken it straight to the dealership they test drove it and they are clueless on how to fix it. This has been going on for 6 months.

So regardless of mode / driving conditions etc - you always have zero boost? That is terrible! How many km did you have on it when this first started? How many km now? Did it start as an occasional thing - before becoming an issue 100% of the time? Do you have any mods?

You are a very patient person. It has only happened to me once and I was pretty disappointed, but going on for 6 months is ludicrous - and makes me wonder whether it is time to assert your legal rights. refer here for a few thoughts - https://legalvision.com.au/the-acl-and-lemon-laws/
I don't think that anyone could argue that no turbo boost in a new twin turbo car is anything other than a major failure - and you have certainly not got what you paid for. I know from my own limited experience that my 0-100 times increased from sub 5sec to almost 11sec when I had zero boost (that's like buying a Stinger and getting a Picanto)! The law says that you are entitled to a repair or a replacement or a refund ... and since 10 attempts at repairing have failed, it is well past time to proceed to the replacement or refund stage.

Give the forum members a few more details. Maybe there is someone out there that can help you resolve this peacefully and quickly.

Wow 10 times? I’d get rid of the car.
