  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Genesis G90 2018 transmission issues.

Vasy - here are your statements below in quotes. I can assure you I would NOT do any of these recommends. If I were driving a 20 year old jalopy, I would do this. I am driving a vehicle less than a year old, with 8,000 miles for which I paid $75,000. Genesis needs to step up and correct this on all V8's on the road. I will continue to be a road warrior on this issue, there is no room to allow this error on Genesis' part to continue.

"That is, carry a gallon or coolant (diluted and ready to use), funnel and a rag (to open a cooled-down but still warm radiator cap). More importantly, check coolant level regularly at your home. Occasionally you need to remove radiator cap (totally cold engine) and check level inside the radiator."
 
To Ann L -- I completely agree with you that Genesis should be more proactive about fixing this.

To Vasy -- As an engineer who spent 40% of his career designing control systems and the other 60% building safeguards for them based on failure analysis, I understand the concept of insurance - rational or not. Don't laugh. My coolant level is fine. But I just put a gallon of anti-freeze and a funnel in the trunk. ;-)

My letter to Genesis which I will deliver tomorrow follows --
Date of Document: 3/3/19
Genesis KMGH54JHXJU043942
Documents:
435831 San Tan Hyundai, Gilbert, Az 85297, 8/3/18
661021671679/1 Chapman, Scottsdale, Az, 85257, 1/16/19
451703 San Tan Hyundai, Gilbert, Az, 85297, 2/13/19

Issues:
See documents above.
Additional comments to issues:
Although the vehicle has been in for routine services on 8/3/18 and 1/16/19 the vehicle issues of TSB 18 at 017 1 and MCN 5NP C8X51-12 were not documented or performed by the dealerships. The owner on 2/13/19 experienced a system failure.
However, the vehicle was serviced twice for the same routine service within 1274 miles of the first service (see documents above).
Customer concerns and additional concerns this owner had not experienced were issues brought up by other owners on Genesis Forum and were voiced to Brian 714 594 1524 at Genesis Customer service in February 2019.
As a result of my discussion with Brian, on 3/4/19 the car will be inspected at Chapman due to owner’s concerns of residual damage due to driving the vehicle while overheating on 2/13/19, and a new concern over the vehicle not starting after 3 tries, and finally started on the 4th try which occurred last week.
Owner’s current comments:
What protocol does Genesis follow when the car is in for routine services? Are all issued TSB and MCNs reviewed and the auto checked for these issues? Is the coolant routinely checked? If not, why not?
Genesis had every opportunity to remedy the situations prior to the failure/performance I experienced, and yet they failed to do so. At this point my confidence that my vehicle will be serviced to prevent future issues with the vehicle is very low.
I purchased/leased this vehicle because it was a superior performing vehicle and still feel that way. However, the service of the vehicle is poor.
I am requesting a face to face discussion with Genesis highest level of management in the Phoenix area that will result in both buyer and seller mutually satisfied going forward.

Sounds like a reasonable request. Laid out plain and simple with facts.
 
Could someone post a link to the TSB; I'd like to have it in my records. I have an '18 G80 5.0
 
Looking to update and upgrade your Genesis luxury sport automobile? Look no further than right here in our own forum store - where orders are shipped immediately!
Good info here for my 15 5.0 but for now, I'm keeping my eye (or better yet - my nose) on the engine for this problem. Is it safe to say that if this o-ring were to fail that it would start leaking and not totally fail within a short period of time? If that's the case, one should be able to smell coolant from the top of a hot engine - right??

Your and Vasy's positions aren't mutually-exclusive. Genesis certainly should make your car whole again, whatever it takes, and should offer to inspect and possibly change the O-rings in all vehicles under the TSB. However, if I had a 5.0 and were driving much beyond my local area, I'd follow Vasy's advice as well. It doesn't help to be right when you're stranded hours from a dealer. I hope that everyone affected gets this taken care of.

Has anyone with the twin turbo engine experienced similar issues? I haven't, but that's no guarantee.
 
@ waveman-This O ring issue seems to only effect
5.0 litre cars whether G80,Hyundai Genesis & G90
according to the service bulletin .

I smelled coolant 10 months ago, and told the service dept. I was told it was a new car and some of the fluids odors will eventually disappear. The smell eventually disappeared after a few months. 5000 miles and 10 months later the fluid was totally gone and my vehicle overheated on a Phoenix freeway. Had I known this was a potential issue I would have insisted the service departments check it out on the two routine times the vehicle was in for routine service at 2 different Hyundai dealerships in Phoenix in these 10 months. Yes, Genesis needs to recall. My vehicle today is in for a check to make sure there is no residual damage and also my vehicle is having a paused start of about a few seconds after hitting the start button. This is a new symptom which is also being checked. I discussed a recall with the Phoenix Chapman Hyundai service department dealership and he said he has repaired two vehicles recently at his dealership with the o ring issue. He feels before they issue a recall they will make sure all the repaired parts (o rings) are in stock. My vehicle was at the dealership 8 days before parts arrived and it was repaired. I have documented all of this in a memo (see memo posted last week) to Genesis Customer Service urging a recall in the last few days. I will advise when I hear from Genesis Customer service.
 
Just picked the car up for the recheck and everything checked out fine. In driving the car home, I am getting the coolant smell again. Something is not right. Here we go again.

Maybe it is old stuff, they topped it off or all of this discussion has your nose remembering it. I would suggest putting all of this behind you and not thinking about it and just enjoy your car. Odds are everything will be fine.

It may just be residue from the work they did. Not uncommon. Keep an eye (or nose) on it but meantime, enjoy the ride. If it was properly fixed you should have a nice car for a very long time.
 
If you are carrying coolant and a funnel in a $73,000 car trunk, your crazy and not getting your money’s worth.

You should hope and want this to happen to your car, and then press the little button on the mirror for service. That is what that is for, and that is how you maintain piece of mind. This is the first time I have heard of a new car overheating in my whole life! You might as well plan to win the lottery if you are worried about this happening to your G90.

BTW, just got my G90 5.0 service at the Johnson Genesis Hyundai dealer. Not a separate dealership, but that place rivaled the Ridgefield BMW dealership in service, infrastructure and goodies in the waiting area. It was a top notch facility. If all the Hyundai dealerships were like this they wouldn’t need to be separate. They took excellent care of me.
 
I didn't win the lottery and my 2018 G90 overheated.

You won the lottery! The prize was a free trip to the mechanic. :)

I am not trying to minimize, deny or belittle your negative experience, I am just saying that in the time of lean manufacturing, and 6 sigma quality controls you indeed had something occur that is on par with odds of winning the lottery when you take into account the entire new automobile population.

You may never have an issue again the rest of your life. The odds are in your favor.

I think the flaw in your argument is that there is a known issue with the part used in the manufacturing of certain G80s and G90s. Given that, the odds are greatly increased that there will be a failure.

If you are saying that the affected G80s/G90s are a very small percentage of all of the vehicles manufactured so there is a tremendously small percentage chance of any car at random having the problem, that would be true but not relevant to the situation.
