2015 5.0 Reliability To 200K

[PETER.RHOADS.bills@GMAIL.]

Hello All, Just curious if anyone has any real world experience of a 2015 Genesis (esp 5.0) lasting to 200k. I am coming from driving Toyota Avalons for the past 20 years and have never had to change an engine, transmission, AC unit, or hardly anything else, all of them lasted well past 200k miles (I heard my old 95 Avalon went past 300k miles by the person who purchased it from me), and I got oil changes well past recommended timing, (10-15k). I don't want to set the bar too high, and the 2015 is a thing of beauty with lots of great features, but I hear people on here talking about transmission changes on these models like it is a normal thing and it shocked me a bit. The other thing I noticed reading these forums is nobody seems to know how these cars actually perform past like 150k miles, all of the comments seem to be from people with less than 100k miles. Based on my typical usage (based on the Avalon) I would like this car to last to 200k miles, if I have to do regular oil changes every 5k miles, no problem, but I don't know that we even know it that is enough since nobody is sharing that experience of the car lasting that long. Is this car basically expected to die at 150k miles? Every time I got rid of my avalon, it was because of some cosmetic reason, I was just getting tired of it, never because it just quit working.

Well, I change my oil every 4k miles and my 2015 5.0 engine looks almost new on the inside with hardly any wear at 90k miles. So I would say yes to a 2015 5.0 engine easily going 200k miles without any major internal engine repair under normal conditions with 4k miles oil change intervals.

I cannot speculate on how well a 5.0 engine with longer oil change intervals will last since some engines are very sensitive to longer oil change intervals which can shorten the lifespan of the internal parts like the timing chain guides and tensioners. I do not know how well Hyundai engines will hold up with longer oil intervals that exceed 4k miles.

My engine internals at 90k miles with 4k miles oil changes. Almost new.

I just hit 120k like two days ago

With all due respect, I don't think you can know the 200k reliability unless you have actually seen it last 200k. Engine reliability is actually not the main problem I see with these cars, it is more transmission reliability, which could be a repair cost in excess of $10k, and massive electrical failures which could be pricey and could have knock on effects if the electrical goes out while driving. Without these two failure modes, I think I could live with the other minor issues. Like I said, most people on here are less than 100k, including yourself. Many people are buying these cars with 100 - 120k miles used because of they are relatively inexpensive yet offer great features, but that calculation turns upside down if you have to spend 30k on repairs over the ownership period. Forums are a great resource to try to connect with real live people who have first hand experience with the exact scenario you are facing, the fact that I can not find anyone on this forum with miles in excess of 150k is a bad sign in itself.

This gotta be a bot.

I am only giving my opinion based on the condition of the engine at 90k miles; which is speculative at best I agree since anything can happen by 200k miles. My point is that the 5.0 TAU engine is well made and is not showing any type of failure point near 100k miles of use with 4k mile oil changes.

My 2015 Genesis only had two real problems in 90k miles not related to an mistake I made. The alternator and a bad taillight wiring harness. Both were fairly inexpensive and simple repairs.

The only reason why my engine were torn down was because I ended up damaging my front lower timing cover during an oil sensor change; not from any mechanical break down. Heck the oil sensor was still working, but I decided to change it when I was swapping my alternator.

Time will tell if the 2015 Genesis will run pass the 200k mile mark without any costly major repairs. My guess is that it has the potential based on other cars I have owned and worked on including Lexus( I own a 2015 Lexus RX350 AWD with 180k miles).

Note: Used 2015+ Hyundai Genesis/G80 transmissions are fairly cheap at about $1000 which means that the demand is not that high for them; so the transmissions are not failing as frequently as you claim. The main issue with the Hyundai 8 speed transmission is usually related to shift solenoids in the valve body(easy fix), not any major internal transmission failure.

 

[PETER.RHOADS.bills@GMAIL.]

Appreciate the detailed reply. Do you know if the solenoid issue in the transmission will cause the transmission to fail if not changed? Looking at a 2015 5.0 right now with 110k miles and carfax shows the transmission was just replaced, not sure if it was because of the solenoids or something else, and also not sure if the replaced transmission is now free of the solenoid issue. Any way to check for that?

To be honest; I do not know what will happen if a rough shifting transmission due to a bad solenoid is not addressed. It could wear out the internal clutches I suppose.

The only way that I would know if the transmission is good or not is if the transmission shifts smooth or not as with any used car I would buy. A bad solenoid usually cause rough and harsh shifts. If the transmission shifts smooth without any noticeable performance issue than it should be fine.

 

[PETER.RHOADS.bills@GMAIL.]

Do the rough shifts occur during downshift mainly?

I do not know.

My 2015 Genesis do not have any rough shifting so no experience with that problem. You will just have to test drive the car you may buy and pay attention to how it shifts overall and decide if the car is for you or not.

Asking questions about the car will not tell you if the particular Genesis you want to buy is good or not. Just like any used car you will have to drive it and pay attention to how the transmission feels as you drive it. If it feels off then walk away from the car and do not buy it.

Love the colors, but I am looking at the one in the link below, got them down to 12k, which seems like a steal to me, but when you look at the maintenance history in the carfax, they had some oil change gaps, no transmission oil change, and they just replaced the transmission. Also, when I test drove, the car shut down when I put it in reverse the first time. I restarted the engine and all of these warning lights came on, something about different systems not working, etc, a bunch of them, but no check engine light. I test drove it in this condition, and I was getting poor acceleration (bear in mind, this is a V8 5.0L), and it seemed like a no-go.

But when I got back to the dealership, I tried to restart the car, and all of the problems suddenly disappeared, all normal. So we took it back out for a 2nd test drive, and everything seemed normal, very powerful acceleration, no warnings, everything good. I had read somewhere that this car can "glitch" on you and a restart will fix it, but this seemed more troubling. Not sure if this kind of glitch is well known, or if it happens frequently or while driving. Any input would be welcome, thanks!

I would not buy that Genesis. Random shutdowns on any car is a big warning flag.

My 2015 Genesis never had any random shutdowns; not a normal issue with a Genesis.

It seems like it would be best for you to stick with used Toyota models or maybe even Lexus since you do not really seem to want a Genesis. Your posts are mainly criticizing the Genesis as inherently flawed.

I actually love the car, I havent test driven a car that wowed me like that, and it is plenty roomy for a 6'5" guy. Just trying to make sure I dont buy the wrong car, thanks for the feedback.

I hear you, but it will be hard to find a used car that will be less problematic as your old Toyota Avalon with any other car brand including Genesis. Toyota are boring cars(pre-2023 models), but very reliable overall due to their simplicity compared to the competition.

Genesis models will not be problem free pass 100k miles or even before. In my opinion, Genesis problems are more of a nuisance than any real problems that will affect how the car drives. But, the 2015 Genesis does have some flaws that can be a deal breaker for some; especially coming from a Lexus or Toyota.

Heck, even used Toyotas can be the "wrong"cars if you get a used one that was not taken care of. Used Toyota/Lexus models with the 3.5 engines can have leaking oil lines, leaking front timing covers, leaking lower oil pan seals,etc; so again any used car can be a "wrong car" regardless of brand.

 

[skipgen]

Yeah. I've got ~112k on my 5.0 Ultimate... The problems I have fall into the "nuisance" category, rather than outright mechanical failure. It's been way too hot here in Texas to bother with most of them.

- Driver's side mirror has stopped folding. Garbage plastic gear inside mechanism. Metal ones can be found online. PITA to disassemble. Been too lazy. I'd probably finish breaking it anyway.
- Faulty driver's side front parking sensor. Not hard but 2 person job - no volunteers @ 103 degrees...
- Trunk open button rubber has disintegrated. Laziness & Heat Wave strike again.
- Occasional weird trans shifting. The transmission programming on these cars is pretty dimwitted at best. I was getting some thunks & flare here & there. Nothing serious. Although, most of it was alleviated by changing fluid & filter - it will never be confused with a ZF box.
- Gasket around 3rd brake light starting to perish. Glare at night getting pretty irritating. May have to deal with it soon.

+1 for the 3.5L oil leaks. I bought a used RX350 with great service record and about 2 weeks later it was literally pissing oil all over the ground. Luckily I caught it before going too far and was able to limp it back home. Dealer picked it up and replaced the oil cooler line for free, but had I gotten on the highway this could've been a completely different story.

Anyway, to the OP - your best bet is to do your due diligence. If it doesn't feel right, don't buy it. Any car can last 200k with the right maintenance and attention - even a german car. But buying one with a history of the exact problem you're trying to avoid is not a good place to start.
My $0.02

I am glad you caught the problem before it destroyed your engine.

My 2015 Lexus RX350 has an slow lower oil pan leak(no drips, but seeps). I will swap out the pan when I finish repairing the Genesis. Toyota/Lexus engines are good engines, but they do have similar problems(oil leaks, defects,etc) like any other engine. The 3.5 V6 main issue is the rubber oil cooler and VVT line used in the older 3.5 engines until about 2012 when Toyota upgraded the lines to metal. Those rubber line leak problems can destroy an engine fast under speed.

I would also have the dealer check your VVT line as well since it is rubber like your oil cooler line; unless it was already changed out for the metal line. However, if your oil cooler line was still rubber then the VVT line was probably not changed out either.

Good to know, I'll have them check it out. I doubt it was done since the oil cooler was a free service

You listed nearly all the "common " problems the Genesis will have by 100k miles. The good news is that you did not have fix any engine problems that would have left you stranded on the road. The 2015+ Genesis/G80 5.0 sedan is good reliable car to own.
