G70 2.0T 6MT Owner - Has anyone else with this noticed?

[canucklehead604]

They must have seen something other than regular clutch wear. Mfr new car warranty covering clutch replacement is very rare. Other than this, I cannot recall any other report like it... with any brand.

^ agreed, after 2.5 years and 22k miles very rare but good for alledaisy. i had the CSC replaced under warranty years ago on a previous G37S but the CSC was a known issue and i was within powertrain warranty coverage. at the time i paid an extra 1/2hr labour for them to install a newer OEM clutch & cover assembly i provided to them. i figured i'd take advantage of the free warranty labour to future-proof my ride since i bought it 2nd hand and didn't know how much meat was left on the factory clutch disc.

That was smart. Most of the cost for clutch change is labor, so might as well.

I'm guessing that the 6MT in our G70 is the same as in the Genesis Coupe 3.8, so 2.0T's more modest torque output should mean longer service life.

Has anyone ever experienced this? Is this normal? I let the car cool down while running for 5-10 mins after getting home.

Genesis sent one of their technicians to Hyundai to look at my car. They ended up replacing all 4 fuel injectors.

Is that your exhaust manifold?

 

[6SPEEDG70]

That is the turbo :/

 

[Volfy]

That is the turbo :/

I was under the impression you were asking about the part that is glowing red hot... which would be the exhaust manifold. Of course that does feed the turbo (circled in yellow) directly.


Neither should be glowing red hot in normal driving.

I doubt the guy was doing 'normal driving'. Ha ha.

 

[canucklehead604]

^ +1. can we get a bit more info on what led to this photo? was this a track day and you snapped the picture as the car started idling down at your 'home base' after a session? unless there's something not functioning properly, i can't see that red hot manifold being a condition under normal street driving, especially after idling for 5-10 minutes.

i've opened my hood plenty of times and never seen anything remotely like that. maybe on a dyno pull at the factory, but not on the street.

Here’s an update - engine light came on. Code P0303 - cylinder 3 misfire. I’ve attached two photos of the spark plug. The insulator seems to be “burnt”. But I checked all the other plugs and they seem to be the same …

I have a 2020 G70 and had rough running, CEL came on...in the 2 weeks until the dealer could fit me in it started flashing, so I stopped immediately and had it towed. Turned out to be the 3rd cylinder misfire...whole cylinder was scored and wouldn't hold any compression. Ended up replacing the entire engine (at 15K miles)

^ wow, that's the first instance i've heard. pretty extreme, but glad you were taken care of under warranty. wonder what happened...

 

[Volfy]

As part of the due diligence to load up on JB4 info, I do remember coming across mentions of cylinder 3 misfiring and the need to pay attention on spark timing on all 4 cylinders, particularly #3. Maybe there is something particular about that cylinder position, possibly running hotter and, therefore, more prone to knock/pinging?

I tried to go back and look for the references, but so far only found:

Cylinder misfire and blown spark plug with LAP3 tune

Wanted to put this out for public consumption. About a week into running the chip, I experienced a cylinder misfire and blew a plug (at a minimum). I am on stock plugs. It may have been bad gas or maybe bad plugs from the start. I had the chip set to 91. Not blaming the chip as the problem could...

Were you running a tune? Spark gap setting?

Did you have any mods on the car (running more boost - via JB4 or ECU tune)?

My car started with the lag you’re describing… then I took it on the highway and it completely died… cars now at the mechanic 400kms from home and they just notified me it would be $3300 to get fixed…..

My car has 17,000kms on it. I’m pretty sure I know how to drive stick so I don’t get it… I’m sure their first assumption is the problem is between the steering wheel and the seat but cmon… no one opened anything up to make sure before blaming the client…

^ not much info there to work with. clearly this seems to be a warranty issue, so contact Genesis and have them sort out a service, including a tow if needed. you have roadside protection which is probably the first call to make. review your coverage to find out what you are entitled to.

obviously do not pay out of pocket for this without going through the motions with Genesis. the only way you would pay is if the failure was to do with a modification you've made. but lacking any background i'll assume that is not the case. whatever issue your car suffered seems to be an isolated thing. i've not heard many stories of G70's 'dying on the highway'.

Sorry about that, zero modifications on the car and everything was running what seemed like perfect the whole way from Montreal to Toronto. Once I got off the highway and stopped, restarted and that’s when the lag started to happen.

Made it to my destination, didn’t move the car for another day until I had to go back.
Took off and the same issue was happening but I made it on the highway, cruising at 125 with a pack, then someone came from behind and when I hit the gas the speed started going down but the engine was revving, all of a sudden the clutch just hit the floor by itself, no more throttle response at all.
Pulled over and had roadside tow me to the nearest Genesis and waited the weekend until someone called today to tell me the damage and that it was “probably” a worn clutch -> but if it isn’t it would “maybe” be under warranty but they can’t know unless I authorize the work to start on the “probable” $3300…

Not gonna lie, I’m salty over this… love this car and it’s a huge disappointment on its first drive more then 200kms

And the fact that since the issue no one wants to help at all, except the service guy but he’ll only help for $3300

You bought the car used, right? If yes, that's the big risk when buying a manual used car. Previous owner probably didn't know how to drive one properly, inadvertently riding the clutch, for instance. That wears it out in a hurry, along with the throw-out bearing. Unfortunately for you, Genesis is correct to assume it's a worn out clutch, so you need to authorize the repair, in case it is. If dealer say it is, demand seeing the clutch first, with somebody who knows, to confirm the diagnosis. Fortunately, it's easy to tell if it's a defect or not most of the times. Good luck, and keep us posted.

First and only owner I hear you though… it’s a fine line

based on Dabg's report, a clutch pedal hitting the floor on its own would not be due to a worn friction disc. so he should have reasonable confidence that the dealer will find a defective part - clearly something broke. a worn disc would show gradual signs of slippage over time - not a sudden failure where the pedal drops to the floor on its own. luckily there are only a few parts involved, which is the beauty of a manual gearbox, so diagnosis once pulled apart should be straight forward. being the original owner and only 17k kms, my guess is that anything other than a worn disc would be at least partially covered,

no idea how they came up with $3300 to replace the disc. that must include all related parts (and labour) like a new flywheel, but the flywheel likely does not need to be changed if Dabg is a skilled manual driver which makes hot spots on the flywheel surface unlikely.

looking forward to a positive outcome for Dabg - the $3300 is certainly a worst case scenario.

Thank you for the input! Makes me a little more comfortable
