Limp Mode?

[thisdude978]

My 2019 G70 with 23k miles seemed to go into limp mode today on the way home from work. At take off from a stop light it barely had any power and was shaking when i gave it gas. The transmission was revving very sporadically and did it over and over again. The car wouldn't allow me to go over 30mph an hour or so. When i got home I shut the car off and back on again and it SEEMS like it might be back to normal, but now I am nervous about taking it on the highway. No check engines lights of any kind. When I parked it was still shaking and hesitating until I shut it off.

Any advice would be appreciated.

Engines rev, transmissions shift or slip.
Shaking is usually an indicator of misfiring, which can do damage if you continue to drive.
I assume your 2019 is still under warranty, so I advise you to take it to your dealer ASAP. The more miles and drive cycles you put on it, the less likely the diagnostic information that they will need will still be there.

I just took it for a drive around the town and gave it a good run and it seemed perfectly fine. I think I will make an appointment tomorrow just to have them look at it. I appreciate the reply.

I found this when looking on the Genesis Owner's site. Should I be concerned?

Maybe an ignition coil? No code is odd..

 

[thisdude978]

I thought so too. Would you be worried if you saw all those codes in the history? I attached an image with code history. Thanks!

Hmm, I wonder if your battery is not strong enough. Newer cars these days go nuts when there isn't enough voltage.

My 2022 G80 still under the 1 yr warranty went into limp mode several times on I 95 while I was driving 75-80 mph. It just slowed down. I pumped the gas pedal and it resumed normal speed 3 separate times. The 4th time nothing helped. I had to get over to the right lane shoulder for safety to the consternation of 2 semi trucks in the middle and right lanes that blasted me for going so slow! Genesis in Savannah has my car for 2 weeks and I still do not have an update on my vehicle. I was on 95 from NC to Florida when the car broke down in Savannah. It took Genesis 18 hours to tow my vehicle to the Savannah dealership. I had no car for 1 week and have had a rental vehicle for the last week. I never received a call back from the Savannah Dealership after 4 calls. 2 the the GM and 2 to the service mgr. The Stuart Florida Dealership, where I purchased the vehicle, was not helpful at all. As a matter of fact they were rude. The customer service I expected from promises made when I purchased the G80 never happened. What a disappointment the Genesis corporation is. What is the sense of manufacturing an expensive beautiful car that is dangerous to drive, and breaks down in the first year? "I'm so sorry, let us provide you with a loaner car to make up for the problem" is the response I expected but never received.

Do you have the 2.5T or 3.5T? Just curious.

Jupiterose,

If you haven't already done so, I would urge you to file a complaint with the National Highway Traffic Safety Administration. Whether a vehicle should be recalled is going to be dependent on how often complaints are filed and whether the regulators (NHTSA) are aware of the problem. Something very similar happened to me with my entire family in the car, when my TWO WEEK OLD G80 lost all motive power while traveling on the highway in the left lane at more than 75mph. There was no "limp mode" for me -- rather, all that happened was that I lost all engine power (pressing on the gas pedal did nothing). You can see the complaints for the 2023 G80 (including the complaint that I filed) here: 2023 GENESIS G80 4 DR RWD | NHTSA or you can also go to this webpage to lodge a complaint about your own car: Report a Safety Problem | NHTSA

Just to update my original issue. I brought my 2019 G70 2.0 to another dealer back in January of this year (23) and they actually spent enough time with it to recreate the issue. It was an odd issue that didn't necessarily "throw a code" and so sporadic that it was hard to duplicate, so that was a bit of a relief. The Service Manager there said he was able to recreate the issue and eventually got it to do it with the head mechanic. They were able to see a code (somewhere?) that is was a fuel injector. Mind you before I bought the car a fuel injector was replaced and it still happened. So they had to order the part so I had to pick my car up and bring it back.

When I brought it back (and was given a loaner this time) it first turned out that the first injector didn't fix it, and neither did a second or third one. So they tore it down and found some scoring on the cylinder wall and that's why it was occasionally losing compression under load, and then would be fine once it was turned off and turned back on. It was determined I need a new engine and that was ordered I think the first week of March. Here we are first week of May and I still don't have my car back.

I am not livid only because the second loaner they gave me in the first week of April is a brand new 2023 3.3T with 120 miles and the plastic was still on it. So for now I am enjoying the extra ~115 HP or so while my car was being worked on. It was finally supposed to be finished last week..... so I am just waiting for a return phone call.

How many miles? I thought bad engines were not an issue in 2019, but at least hope my 2023 doesn't have that potential issue. An ex-'16 Optima SX-L with the same 2.0T was affected by the con-rod fiasco, but figured it'd be in the past by '23. We'll see.

What's been miserable for me is that my car failed at highway speeds of 75mph and kept failing over and over for the next half an hour, and then refused to start at all for three hours until I had to have it towed to a dealer. And yet, it showed NO ERROR OR FAULT CODES. That's bananas. First dealership couldn't replicate the problem so they just handed the car back to me and said, "Sorry." Of course it happened again, and guess what? No error or fault codes again.

I have sent Genesis a demand letter under my state's lemon law demanding that they take this car back and refund me everything that I have paid out so far (i.e. a complete refund).

It's frustrating that manufacturers keep adding crap to the vehicles, but don't update their diagnostic capabilities. Due to that, many issues, like the one described above, cannot be troubleshot easily. And with an unrelated issue, a ton of systems get disabled, which makes zero sense. But you seem to have a G80, not a 70, correct? Which they have totally different engines (and infotainment too) as the G70, so not really relevant here at all.

Agreed about the diagnostic capabilities. And yes, you're correct that I have a G80, but the G70 and G80 both have turbo-charged inline four cylinder engines, and although the G80 is a 2.5L versus 2.0 liter for the G70, I'm not sure that I would characterize them as being "totally different." More importantly, the fuel system and associated software components are almost certainly nearly identical, with similar pressure sensors, GDI (gasoline direct injection) pumps, fuel harnesses, etc. Moreover, it's very likely that Hyundai uses the same sort of ECM and TCM software in its cars, and there may well be more widespread problems than are already known (Hyundai recalled more than 57,000 vehicles for problems with its TCMs that resulted in complete loss of motive power barely eight months ago).

 

[joegr]

...I'm not sure that I would characterize them as being "totally different." ...

Please go and do some research on the 2.0T and 2.5T. I think that almost everyone who has would agree that they are very different engines. As such, it is likely that many/most/all the fuel system components are in fact different. Certainly, the software has to be.

Out of curiosity, would you characterize an engine in a car like the 2022 Santa Fe, which has a 2.5L turbocharged inline 4 cylinder, versus the engine in a 2022 Sonata, which a 1.6L turbocharged 4 cylinder as very different as well?

If you would (as I suspect you might), would you be surprised to learn that both those vehicles were subject to the same recall last fall for the same problem with the vehicles' Transmission Control Modules?

No one is arguing the engines in those two cars (or the G70 and G80) are identical, or that they aren't different in certain ways. And, I'm not claiming that everything in the software is identical for different engines. But the components of these vehicles are certainly subject to the same sorts of manufacturing processes and software systems. To think that manufacturers create entirely different software systems from scratch for every version of every model engine ignores the economic problems with such an approach.

So it's fine to think that similar problems with a G70 and G80 cannot result from a problem that affects *both* models, but I don't think it's the most logical conclusion, and it's inaccurate to claim similar problems between the two models are "not really relevant at all."

 

[joegr]

Clearly, you are not willing to research this. This has nothing to do with the slight difference in displacement. Do check it out...

Is there a reason why you're focusing on the question of whether the G70 and G80 engines are similar enough or different enough in your eyes, versus the more important -- and, as you put it -- relevant question about whether problems with the two engines can be caused by similar factors?

You conveniently ignored my question and point about the Santa Fe and Sonata engines -- why is that? Do you think those engines are similar or very different? If you think they are very different, just say so, but that would then just raise the more important question of, "If very different engines are subject to the same problems (for example, software problems) that justify a recall, then why can't that be relevant to the question posed in this post?"

You may be confusing me with another poster. I have only spoken to the fact that these are very different engines, nothing else.
I have not commented on the Sante Fe and Sonata engines because I have not researched those two, and unlike some, I don't like to make comments on things that I am presently ignorant about.
